Introduction to the basic working principle of sanitary valves

Sanitary valve is one of the ball valves, so how do you know the sanitary valve works? Let's have a look! Sanitary valve is a widely used valve, which is mainly used in analog quantity regulation of pipeline medium flow of liquid, gas and air system. It is AI control. In the control of large valves and air systems, electric valves can also be used as two position switch control. Let's take a look at the principle of sanitary valves.

The operating principle of sanitary valve is that sanitary valve is usually connected by electric actuator and valve, and becomes electric valve after installation and commissioning. Sanitary valves use electric energy as power to connect the electric actuator to drive the valve to realize the opening and closing and adjustment of the valve. So as to achieve the purpose of switching or regulating the pipeline medium.

Working performance of sanitary valve: electric valve is usually driven by motor, which is more resistant to voltage shock. Solenoid valve is quick to open and close. It is usually used in places with small flow and small pressure, requiring high switching frequency, and vice versa. The opening of the electric valve can be controlled, including on, off, half on and half off, which can control the flow of medium in the pipeline, and the solenoid valve can not meet this requirement.

Sanitary valves are evolved from plug valves. It has the same lifting action of rotating 90 degrees. The difference of some sanitary valves is that the cock body is a sphere, and there is also a circular through hole or channel through its axis.

The relevant proportion between the spherical surface and the channel port should be like this, that is, when the ball rotates 90 degrees, it should all present a spherical shape at the inlet and outlet, so as to cut off the flow. The electric plastic ball valve can be closed tightly only by rotating 90 degrees and a small rotating torque. The same inner cavity of the valve body provides a small resistance and straight flow channel for the medium. It is generally considered that ball valves are suitable for direct opening and closing, but in recent years, ball valves have been designed to throttle and control flow. The main feature of the ball valve is that it has a particularly compact structure and is easy to operate, repair and maintain. It is suitable for ordinary working media such as water, solvent, acid and natural gas, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.

The ball valve body can be integral or combined with chemicals. The ball valve is light and small, can be made into a large diameter, reliable sealing, especially simple structure and convenient maintenance. The sealing surface and spherical surface are usually closed and are not easy to be eroded by media. It is widely used in various industries. Electric plastic ball valve and plug valve belong to one type of valve. Only when the closing part is a ball, the ball is used to rotate around the center line of the valve body to open and close.

Through the introduction of sanitary valve manufacturers above, you should know how sanitary valves work!
