Technical Field

The invention relates to a one-way valve, in particular to a novel diaphragm metering pump integrated one-way valve.

Background

When the one-way valve is used for conveying the regenerated catalyst, the problems of high material temperature, zirconia and other hard particles and high outlet pressure exist in the regenerated catalyst slurry, so that the conveying difficulty is high and the conveying state is poor.

The conventional check valve has the following four disadvantages in use:

firstly, adopt the feeding mode of height that advances that declines, because there is a large amount of solid stereoplasm granules in the fluid, lead to the position of import to take place to block up easily.

Secondly, a single-ball single-seat mode is adopted, and under a high-temperature and high-pressure environment, the valve seat and the valve ball are easily subjected to the impact of solid particles to cause a serious abrasion phenomenon, so that the service life of the check valve is short.

Thirdly, the adoption of more expensive hastelloy and large loss lead to higher production cost.

Fourthly, the seat returning is carried out only by the gravity of the valve ball, so that the seat returning time is long, and the transportation capacity is reduced.

Chinese patent No. CN205744411U discloses a check valve applied to a fluid medium containing solid particles, which includes a valve guide, a ceramic valve seat, a spring, and a ceramic valve ball, wherein the lower end of the valve guide is provided with an elliptical flow passage and a working flow passage, the working flow passage is provided with a working chamber and a valve ball moving chamber, the ceramic valve ball and the spring are respectively arranged in the working chamber and the valve ball moving chamber, the upper end of the spring is pressed against the ceramic valve ball, the lower end of the spring is pressed against the valve guide, the ceramic valve seat is provided with a working hole, the ceramic valve seat is fastened on the valve guide, the working hole on the ceramic valve seat is opposite to the valve ball moving chamber on the valve guide, the ceramic valve ball is pressed against the lower edge of the working hole, and the elliptical flow passage and the working flow passage are communicated through the valve ball moving chamber; through this technical scheme, overcome the defect that exists among the prior art, have sealed tight, life cycle is long, the precision is high, reaction rate is fast, transport medium ability reinforce, simple structure, convenient assembling.

However, although the conveying capacity of the check valve is ensured to be strong by the resilience force of the spring, in the actual use process, it is found that the gap of the spring is easily filled with solid particles, the resilience force of the spring is easily reduced or even disappears in the process of gradual use, and finally, the valve ball is fixed at the inlet position, so that the fluid medium cannot be conveyed continuously.

Disclosure of Invention

The invention aims to provide a novel diaphragm metering pump integrated one-way valve. The novel diaphragm metering pump integrated check valve can solve the problem that the resilience force of a spring is gradually reduced.

The invention aims to be realized by the following technical scheme: the utility model provides a novel diaphragm metering pump collection dress formula check valve, includes the disk seat, install a plurality of valve balls in the disk seat, a plurality of valve ball bottoms all are connected with spring one, spring one bottom is connected with the sliding block, the sliding block slides and is connected with spring two, spring two is connected with the mount pad.

After adopting above-mentioned technical scheme, when fluid medium impact valve ball, valve ball moves down for a spring accumulation resilience force. At this time, the fluid medium passes through the check valve through a gap between the valve ball and the valve seat. The spring then springs back, so that the valve ball closes the passage for the fluid medium. The process is circulated, and the valve ball bounces back and forth due to the existence of the first spring, so that the conveying efficiency is ensured. In the long-time use process, because solid particles can be attached to gaps among the first springs, in order to solve the problem, the sliding block is added, so that the resilience force of the first springs is released on the sliding block, and external force is applied to the second springs when the sliding block moves downwards, so that the second springs accumulate elastic force. In the process, the second spring is not directly contacted with the fluid particles, so that the problem of solid particle accumulation does not exist. Meanwhile, the range of the first spring is increased, the first spring is large in displacement and large in movement amplitude, and the possibility that solid particles are attached to gaps is reduced, so that the problem that the resilience of the first spring gradually disappears is solved.

The invention is further configured to: the utility model discloses a valve guide device, including slider, mount pad, sealing ball, sliding block, spring two, the mounting seat is provided with the wedge that corresponds with most advanced, and the mounting seat is provided with the wedge that corresponds with most advanced, wedge one end butt has the ball sealer, the mounting seat corresponds the ball sealer and is provided with the sealed chamber that can supply the card to go into the ball sealer, ball sealer one side is connected with spring three, spring three and valve guide fixed connection.

After adopting above-mentioned technical scheme, after long-time the use, solid particle piles up in the space between mount pad and valve guide, can comparatively serious influence the effect of sliding block. At this time, it needs to be cleaned. The installation seat provided by the invention can be separated from the valve guide, so that the installation seat can be used for multiple times. When solid particles in the fluid medium are accumulated in the gap, the sliding difficulty of the sliding block is gradually increased, the resilience force of the second spring is gradually reduced, and the valve ball is fully opened and loses the function of the one-way valve. At this moment, the sliding block can move down to the bottom, drives the depression bar and removes, and the pointed end of depression bar exerts pressure on the wedge for two wedges remove to both sides respectively, and the in-process that the wedge removed drives the ball sealer and outwards removes, thereby makes the ball sealer leave the seal chamber. At this point, the sealing ball no longer secures the mount and seals against the mount. When the staff can discover that there is the fluid leakage, after closing the check valve manually, can directly pull the pointed end and pull out the valve direction with whole mount pad, clear away the solid particle in the check valve and on the mount pad, later the mountable is got back and is continued to use.

The invention is further configured to: a guide surface is disposed within the valve guide.

After adopting above-mentioned technical scheme, through the setting of guide face for fluid medium can flow through the guide face after passing through the valve ball, the solid medium that has significantly reduced enters into the possibility in the space between valve guide and the mount pad, reduces the abluent frequency of maintenance. Meanwhile, the fluid medium can be conveyed more easily, and the conveying efficiency is improved.

The invention is further configured to: a gap is formed between the valve guide and the mounting seat, and a guide block fixedly connected with the mounting seat is arranged at the bottom of the gap.

After adopting above-mentioned technical scheme, when solid particle entered into the space, because the setting of guide block for solid particle can pile up on the guide block. When the quantity that solid particle piles up is great, can exert the yawing force to the sliding block on the guide block for the degree of difficulty that the sliding block kick-backed is more and more big, finally makes the pointed end of sliding block bottom promote the wedge, reminds the staff to carry out cleaning.

The invention is further configured to: the valve guide is connected with a valve seat, the valve balls are arranged at the bottom of the valve seat, and a base is arranged outside the valve seat.

After adopting above-mentioned technical scheme, through the setting of disk seat and base for the valve ball is in between disk seat and the valve guide, guarantees connection stability.

The invention is further configured to: and a sealing gasket is arranged among the base, the valve guide and the valve seat.

After adopting above-mentioned technical scheme, through the setting of seal gasket for in the course of the work, the problem that unexpected fluid leaked can not take place.

In summary, the present invention has the following advantageous objects:

1. the first inventive point of the invention is that: the problem that a single spring is used in the prior art is solved, the elastic part combination between the first spring and the second spring is used, the movement path of the first spring is improved, solid particles are prevented from being accumulated and attached between the gaps of the first spring in the use process, and the service life of the integral one-way valve is prolonged.

2. The second inventive point of the invention is that: use the setting of detachable mount pad for spring two is in the use, and the solid particle between the space is more and more, and when finally leading to the sliding block to be difficult to kick-back, the depression bar of bottom exerted pressure to the wedge, forces to make the ball sealer leave the mount pad, thereby appears artificial leakage problem, reminds the staff to handle.

3. The third inventive point of the invention is that: when the artificial leakage problem appears, the staff can be convenient pull the pointed end and all shift out the valve direction with the position of mount pad to valve ball to wash in mount pad and the valve direction, make things convenient for the reutilization.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

As shown in fig. 1 and 4, the novel diaphragm metering pump integrated one-way valve comprises a valve seat 1, a valve guide 2 and a base 3. The valve guide 2 is clamped with the valve seat 1, and a sealing gasket 4 is arranged among the valve seat 1, the valve guide 2 and the base 3. Meanwhile, a positioning pin 5 is arranged between the valve seat 1 and the valve guide 2, so that the valve seat 1 and the valve guide 2 are stably connected, and the installation can be realized without positioning.

As shown in fig. 2 and 3, the valve seat 1 is provided with three inlets 6, and a valve ball 7 is arranged inside each inlet 6. The bottom of the valve ball 7 is abutted with a first spring 8. The bottom of the first spring 8 is fixedly connected with a sliding block 9. The sliding block 9 is connected with a second spring 10 in a sliding manner. The second spring 10 is fixedly connected with a mounting seat 11. The bottom of the sliding block 9 is fixedly connected with a pressure lever 12, and a second spring 10 is wound outside the pressure lever 12. The bottom of the pressure rod 12 is provided with a tip 13. Wedge blocks 14 corresponding to the tip 13 are provided at both sides of the tip 13. One side of the wedge block 14 is abutted with a sealing ball 15. One end of the sealing ball 15 is fixedly connected with a spring III 16. Spring three 16 is fixedly connected with valve guide 2. Meanwhile, a mounting hole 17 for mounting the spring and the sealing ball 15 is formed in the valve guide 2. A sealing cavity is arranged on the mounting seat 11 corresponding to the position of the sealing ball 15. When the sealing ball 15 enters the sealing cavity, the mounting seat 11 is fixedly sealed.

Preferably, a guide surface 18 is provided in the valve guide 2. The provision of the guide surface 18 facilitates the outflow of the fluid medium along the guide surface 18, preventing fluid from being retained in the valve guide 2, while ensuring the delivery efficiency.

Preferably, a gap 19 is formed between the valve guide 2 and the mounting seat 11, and a guide block 20 fixedly connected with the mounting seat 11 is arranged at the bottom of the gap 19. Through the setting of guide block 20 for solid particle piles up can produce pressure to sliding block 9 when too much, thereby makes sliding block 9 can not kick-back, needs the staff to wash the maintenance this moment.

The whole working process and effect are as follows:

when the fluid medium impacts the valve ball 7, the valve ball 7 moves downwards, so that the spring 8 accumulates the resilience force. At this time, the fluid medium passes through the check valve through the gap between the valve ball 7 and the valve seat 1, and the fluid medium is efficiently conveyed by the guide of the guide surface 18. After that, the spring 8 springs back, so that the valve ball 7 closes the passage of the fluid medium. And the process is circulated, and the valve ball 7 bounces back and forth due to the existence of the first spring 8, so that the conveying efficiency is ensured. In the long-time use process, because solid particles can be attached to gaps between the first springs 8, in order to solve the problem, the sliding block 9 is added, so that the resilience force of the first springs 8 is released on the sliding block 9, and external force is applied to the second springs 10 when the sliding block 9 moves downwards, so that the second springs 10 accumulate elastic force. In the process, the second spring 10 is not directly contacted with the fluid particles, so that the problem of solid particle accumulation does not exist. Meanwhile, the range of the first spring 8 can be increased, the first spring 8 is large in displacement and large in movement amplitude, and the possibility that solid particles are attached to gaps is reduced, so that the problem that the resilience force of the first spring 8 disappears gradually is solved.

After long-time use, solid particles are accumulated in a gap 19 between the mounting seat 11 and the valve guide 2, and are obliquely accumulated in the gap 19 under the action of the guide block 20, so that the sliding effect of the sliding block 9 is seriously influenced, and the sliding block 9 cannot rebound. At this time, it needs to be cleaned. In the prior art, the mounting seat 11 can not be used and discarded, and can be separated from the valve guide 2, so that the mounting seat can be used for many times. When solid particles in the fluid medium are accumulated in the gap 19, the sliding difficulty of the sliding block 9 is gradually increased, the resilience force of the second spring 10 is gradually reduced, and the valve ball 7 is fully opened and loses the function of the one-way valve. At this moment, the sliding block 9 can move downwards to the bottom to drive the pressing rod 12 to move, the tip 13 of the pressing rod 12 applies pressure to the wedge-shaped blocks 14, so that the two wedge-shaped blocks 14 move towards two sides respectively, and the wedge-shaped blocks 14 drive the sealing ball 15 to move outwards in the moving process, so that the sealing ball 15 leaves the sealing cavity. At this time, the sealing ball 15 no longer fixes the mount 11 and seals the mount 11. When the staff can discover that there is the fluid leakage, after closing the check valve manually, can directly pull pointed end 13 and pull out valve direction 2 with whole mount pad 11, clear away the solid particle in the check valve and on the mount pad 11, can install back the back and continue to use afterwards.
