Description

water pressure control valve

Technical field

The utility model belongs to the technical field of control valves, and specifically relates to a water pressure control valve.

Background technique

With the continuous improvement of social development level and residents' living standards, users pay more attention to the function and quality of washing machines when choosing to purchase washing machines. According to incomplete surveys, users pay more attention to the amount of toiletries and the classification and cleaning function of clothes when cleaning clothes. The water path of existing washing machines is usually controlled by a solenoid valve, which requires a special circuit board to turn on or off the solenoid valve through electrical signals. Since the solenoid valve can only be used when it is powered on, its structure is often complex and its stability is poor. At the same time, the iron core on the solenoid valve will produce loud noise when it is closed, resulting in poor user experience. Therefore, it is necessary to design a water pressure control valve to overcome the above difficulties.

At this time, there is only an elastic diaphragm between the second water inlet channel and the second water outlet channel, which is not completely sealed. The second water inlet channel and the second water outlet channel are still connected to each other. When water is supplied to the first water inlet channel of the valve body, the water pressure at the end of the elastic diaphragm close to the first water inlet channel will increase, so that the water flow will continue to squeeze and contact the elastic diaphragm, and the elastic diaphragm will Elastic deformation occurs, so that the elastic diaphragm will squeeze and contact the water inlet of the second water outlet channel, so that the second water inlet channel and the second water outlet channel are in a completely sealed and isolated state. When the first water inlet channel of the valve body is blocked by water, the elastic diaphragm automatically returns to the default initial state, and the second water inlet channel and the second water outlet channel automatically recover to the initial conduction state.

When the valve body passes water, the elastic diaphragm will deform. The water in the valve body will flow in from the first water inlet channel, and then flow out from the first water outlet channel; then the accommodation space on the left side of the elastic diaphragm will be large, and the elasticity will The accommodation space on the right side of the diaphragm will be smaller, so that the excess air in the valve body will be discharged from the pressure relief port.

Preferably, the first protrusion faces the water inlet of the second water outlet channel and extends into the second water outlet channel; the first protrusion is provided with a first groove that is recessed toward the surface of the bracket.

When there is no water in the first water inlet channel of the valve body, the valve body uses the second water inlet channel and the second water outlet channel to transport water. When water enters the interior of the valve body from the second water inlet channel, it will squeeze and contact the surface of the elastic diaphragm, so that the elastic diaphragm will leave the water inlet of the second water outlet channel, and then the water will continue to flow from the second water outlet channel from the valve out of the body.

Preferably, an annular sealing portion is provided on the edge of the elastic diaphragm, and an annular groove is provided in the valve body for installing the annular sealing portion. The outer contour of the annular sealing portion matches the outer contour of the annular groove.

The elastic diaphragm separates the valve body into two independent cavities on the left and right. By providing an annular sealing portion and an annular groove, the sealing performance between the two cavities is better.

Preferably, the elastic diaphragm is made of rubber material.

The elastic diaphragm is made of rubber material, so that the elastic diaphragm has good sealing performance in the valve body and can also produce elastic deformation.

Preferably, a pressure relief port is provided between the first water inlet channel and the first water outlet channel.

Compared with the existing technology, the present utility model has the following beneficial effects: By arranging a control membrane assembly between the second water inlet channel and the second water outlet channel of the valve body, the utility model facilitates the control of the second water inlet channel and the second water outlet channel. The continuity or isolation status of the water outlet channel. In the default state, no water enters the first water inlet channel of the valve body. In this way, the elastic diaphragm does not produce elastic deformation, but only resists the water inlet of the second water outlet channel. Then the second water inlet channel and the second water outlet channel are in a guiding position. communication status. At this time, the valve body controls the delivery of water through the second water inlet channel and the second water outlet channel. When the first water outlet channel of the valve body passes water, the elastic diaphragm will elastically deform, thereby squeezing and contacting the water inlet of the second water outlet channel, so that the second water inlet channel and the second water outlet channel will be in a sealed and isolated state. At this time, the valve body can only control water delivery through the first water inlet channel and the first water outlet channel. Therefore, the utility model facilitates switching of water channels by controlling membrane components, has a simple and reliable structure, a wide use environment, and good versatility.
