Background

In the existing pipeline system, a one-inlet two-outlet shunt valve is often required, for example, a three-way angle valve disclosed in patent application No. 201922113941.7, which includes a valve body, wherein the valve body is provided with a water inlet, a first water outlet and a second water outlet, the water inlet is located between the first water outlet and the second water outlet, a ceramic valve core switch for controlling the water outlet of the first water outlet is arranged at one end of the valve body close to the first water outlet, the aperture of the second water outlet is larger than that of the first water outlet, a ball valve switch for controlling the water outlet of the second water outlet is arranged between the water inlet and the second water outlet, and a sealing cover is installed at one end of the valve body close to the second water outlet. It mainly is that cooperation intelligent closestool and spray gun use, because all have the water switch on intelligent closestool and the spray gun respectively, therefore tee bend angle valve all is generally in normally open state, just closes when intelligent closestool needs maintenance or change, and wherein the spray gun is connected to the second delivery port, and intelligent closestool is connected to first delivery port, and the water in the water pipe flows into in the valve body and flows into first delivery port and second delivery port simultaneously from the water inlet.

In the three-way angle valve, the second water outlet is controlled by the ball core, so that the three-way angle valve has larger water yield, and the washing and cleaning effects of the spray gun are better; however, the ceramic switch is adopted for the first water outlet, and the water flow of the ceramic switch is relatively low, so that the water yield of the first water outlet is relatively low. In order to obtain a large water output from both the first outlet and the second outlet, the following ways are easily conceivable for those skilled in the art:

1. the first water outlet is also used by replacing a ceramic switch with a ball core;

2. the switch control of the first water outlet and the second water outlet is directly cancelled, and the ball valve is directly connected to the water inlet, so that the water quantity fed into the valve body is maximized, and the water quantities flowing out of the first water outlet and the second water outlet are maximized;

3. the switch control of the first water outlet and the second water outlet is directly cancelled, the size of the water inlet is directly increased, so that the ball core can be directly installed in the water inlet, and the volume of the valve body is correspondingly increased.

Disclosure of Invention

The invention aims to provide a water diversion valve aiming at the problems in the prior art, and solves the problem of insufficient water yield.

The purpose of the invention can be realized by the following technical scheme:

the water diversion valve comprises a valve body and a water inlet connecting pipe, wherein the valve body is internally provided with two water outlets arranged in parallel, the water outlet cavity is positioned between the two water outlets, the water inlet connecting pipe is arranged on the side part of the valve body, a ball core is arranged in the valve body, the ball core is provided with a water inlet hole and a first water outlet hole, the water outlet cavity is provided with a connector penetrating through the side part of the valve body, the ball core is arranged in the water outlet cavity from the connector, one end of the water inlet connecting pipe is connected in the connector and matched with the water outlet cavity towards the inner wall of the connector to position the ball core, an included angle is formed between the water inlet hole and the first water outlet hole, the first water outlet hole is communicated with the water outlet cavity when the water inlet hole is communicated with the water inlet connecting pipe by rotation of the ball core, a second water outlet hole communicated with the water outlet cavity all the time is also arranged on the ball core, and the sum of the cross-section flow of the first water outlet hole and the second water outlet hole is not smaller than the water inlet hole.

The water distribution valve is in a normally open state when in use, namely, the water inlet connecting pipe is communicated with the water inlet hole, the water outlet hole I and the water outlet hole II are simultaneously communicated with the water passing cavity, the two water outlets are respectively connected with components needing water, such as an intelligent closestool and a spray gun, and the water inlet connecting pipe is connected with a water pipe of a wall surface. The medium flows into the water inlet hole of the ball core from the water inlet connecting pipe, flows into the water passing cavity through the first water outlet hole and the second water outlet hole respectively, and is simultaneously divided into the two water outlet holes by the water passing cavity to be used by parts needing water. The water diversion valve is characterized in that a water inlet hole and a water outlet hole I are arranged to form an included angle, and a water outlet hole II which is always communicated with a water passing cavity is additionally arranged, and the flow of the independent section of the water outlet hole I or the water outlet hole II is smaller than that of the water inlet hole, so that the size of the water inlet hole can be made larger as much as possible to ensure the water inlet flow, and meanwhile, the wall thickness of the ball core cannot be influenced because the size of the water inlet hole is large (because the size of the water outlet hole I corresponds to that of the water outlet hole II), and the water outlet hole II is always communicated with the water passing cavity without influencing the normal rotation of the ball core to control the opening and closing of the whole water diversion valve; meanwhile, the sum of the cross-sectional flows of the first water outlet hole and the second water outlet hole is set to be not less than that of the water inlet hole, so that the water outlet flow and the water inlet flow can be ensured to be as large as each other, and the two water using components can obtain the maximum water outlet amount at the same time.

In addition, the ball core is directly arranged in the water passing cavity of the valve body and positioned between the two water outlets, the arrangement mode enables the structure of the whole water dividing valve to be simpler and more reasonable, the whole volume of the valve body can be controlled to be smaller and smaller, and the production cost is lower.

The conventional ball core is provided with straight holes, and the medium flows in from one end of each straight hole and directly flows out from the other end of each straight hole, so that the flow rate is maximum. However, in the water dividing valve, the ball core needs to be positioned by matching the water inlet connecting pipe with the inner wall of the water passing cavity facing the water inlet connecting pipe, so that the conventional ball core cannot be used in the water passing cavity, because when one port of the straight hole of the conventional ball core is just communicated with the water inlet connecting pipe, the other port of the straight hole faces the inner wall of the water passing cavity, and thus water outlet cannot be realized.

In foretell shunt valve, the chamber of crossing water include with the intake take over concentric round hole that sets up and with the recess of round hole side direction intercommunication, round hole and recess all communicate with two delivery ports simultaneously, the ball core is located in the round hole and apopore two towards the recess, the connector is the one end drill way of round hole.

The medium is firstly shunted into the two circular cavities from the water passing cavity and then flows into the corresponding water outlet from the circular cavities. Because the circular cavity and the water outlet are arranged on the same central line, and the inner diameter of the circular cavity is larger than that of the water outlet, the flow velocity of the medium flowing into the water outlet from the circular cavity can be increased due to the reduction of the circulation caliber, and the water distribution valve is more suitable for intelligent toilets and spray guns due to the fact that the water outlet is matched with the medium with enough water yield.

In the shunt valve, a rotatable valve rod is arranged in the valve body, one end of the valve rod extends into the round hole and is connected with the ball core, the other end of the valve rod extends out of the valve body, and the central line of the valve rod is collinear with the central line of the water outlet hole II.

The ball core rotates by taking the center line of the valve rod as a rotation center, and the center line of the water outlet hole II is collinear with the valve rod, so that the water outlet hole II can be ensured to be in a state of being communicated with the water passing cavity no matter how the ball core rotates. Therefore, when the ball core rotates to the state that the water inlet is communicated with the water inlet connecting pipe and the water outlet I is communicated with the water passing cavity, the medium can simultaneously flow into the water passing cavity by utilizing the water outlet I and the water outlet II so as to ensure that the two water using components can obtain the maximum water yield.

In the shunt valve, the water inlet hole is perpendicular to the water outlet hole, the valve body is externally provided with two limiting convex blocks, the side part of one end of the valve rod, which extends out of the valve body, is provided with a bolt, and the bolt is positioned between the two limiting convex blocks.
