Technical Field

The invention relates to the field of bathrooms, in particular to an overflow valve capable of improving overflow capacity.

Background

The existing drain valve consists of a valve body, a base and an overflow pipe. Wherein the valve base is communicated with the overflow pipe. Under the normal stagnant water state, the outside air passes through overflow pipe and drain valve base outlet intercommunication. When the overflow phenomenon occurs, water flows from the overflow pipe to the water discharge valve base water discharge port and enters the toilet bowl pipeline. When the drain valve is opened, water flows out through the drain outlet of the drain valve base, and when the drain valve is normally used, the drain outlet of the drain valve base is communicated with outside air through the overflow pipe channel, negative pressure can be generated in the drain channel during draining, and air can be mixed into the drain outlet of the drain valve base together under the action of outside atmospheric pressure, so that the drain channel is not in a pipe full water state, and the drainage speed is reduced.

Disclosure of Invention

In order to solve the problems, the invention provides an overflow valve which can improve the overflow capacity.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the overflow valve capable of improving the overflow capacity comprises a shell, wherein a cavity is formed in the shell, and a water inlet pipe and a water outlet pipe which are communicated with the cavity are respectively arranged at the top and the bottom of the shell. The bottom of the water inlet pipe extends into the cavity, a supporting piece is fixedly arranged on the top wall of the cavity at the side edge of the water inlet pipe, and a lever guide pillar is hinged to the lower portion of the supporting piece. One end of the lever guide post is fixedly provided with a sealing rubber mat which is used for being matched with the bottom of the water inlet pipe in a sealing way, and the other end of the lever guide post is provided with a balance structure body which is used for forming lever balance with the sealing rubber mat and driving the sealing rubber mat to reset upwards.

In one embodiment, the sealing end surface of the bottom of the water inlet pipe is a horizontal surface.

In another embodiment, the sealing end face of the bottom of the water inlet pipe is obliquely arranged, and an acute included angle formed between the sealing end face and the vertical face is 25-65 degrees.

In one structure of the balance structure body, the balance structure body is a balancing weight, and the balancing weight is fixedly connected with one end part of the lever guide pillar, which is far away from the sealing rubber pad, through threads or buckles.

In another structure of the balance structure body, the balance structure body is a spring, one end of the spring is fixed, and the other end of the spring is connected with the bottom of the lever guide post and is in a stretching state.

The top wall of the cavity is fixedly provided with a supporting rod at the side edge of the supporting piece, the lower part of the supporting rod is fixedly provided with a transverse plate at a position lower than the hinged fulcrum of the lever guide post, and the lower end of the spring is fixed on the transverse plate.

Further, the shell include the overflow upper cover and the overflow base of pegging graft each other, the inlet tube sets firmly cover on the overflow, the overflow cap that is used for preventing the vortex from producing is installed at the inlet tube top, the outlet pipe sets firmly on the overflow base.

Furthermore, a disc is fixedly arranged at one end of the sealing rubber pad of the lever guide column, and the sealing rubber pad is fixed to the top of the disc. The top center department of disc upwards extends and forms a reference column, the annular positioning groove has been seted up to the lower part of reference column, the center department of sealed cushion is seted up and is used for the card to go into the through-hole in the annular positioning groove.

Furthermore, two sides of the lever guide pillar extend outwards respectively to form two positioning rods, the supporting piece comprises two connecting plates which are parallel to each other and arranged at intervals, positioning holes are formed in the connecting plates, and the two positioning rods are hinged to the positioning holes in the two connecting plates respectively.

Preferably, in order to prevent the lever guide post from being opened at an excessively large angle, a limiting boss for interference-fitting with the disk and limiting the rotation angle of the disk is formed at the bottom of the connecting plate extending downward.

The invention has the following beneficial effects:

1. under normal conditions, the sealing rubber pad seals and closes the water inlet pipe under the action of the balance structure body, when the drain valve drains water, external air cannot enter the drain port of the drain valve from the water inlet pipe, and the siphon effect greatly improves the drainage speed; when the water pressure on the sealing rubber gasket is greater than the acting force of the balance structure body, the lever guide post drives the sealing rubber gasket to rotate and open the water inlet pipe, and the overflow valve achieves the overflow function.

2. The sealed terminal surface of inlet tube bottom can be the horizontal plane, also can be personally submit 25 ~ 65 inclined planes with vertical, and when sealed terminal surface was the inclined plane, the lever was opened fast, and the flow area is big, and the overflow ability is strong, and lever closing time is short, is convenient for keep apart the air.

3. The balance structure body can be a balancing weight or a spring, the balance effect is good, the structure is simple, and the installation and the disassembly are convenient.

4. Through at inlet tube top installation overflow cap, when taking place the overflow, the formation of the vortex above the inlet tube mouth of pipe has been prevented to the overflow cap, has effectively reduced the noise that the moisturizing sent, and the flow of water tends to stably to there is higher water velocity, thereby has improved the overflow capacity of overflow valve.

5. The limiting boss used for being in interference fit with the disc and limiting the rotation angle of the disc is arranged at the bottom of the connecting plate, so that the situation that the overflow valve fails due to the fact that the overflow valve cannot reset due to the fact that the opening angle of the lever guide pillar is too large can be effectively prevented, and the overflow valve can run more stably.

6. The overflow valve of the invention can be arranged in the overflow pipe of the drain valve to realize the functions of isolating air and overflowing, and can also be independently arranged at the bottom of the water tank to realize the functions of overflowing and water replenishing.
