How Does A Non Return Valve Work

How Does A Non Return Valve Work

A non-return valve, also known as a check valve, is a mechanical device that allows fluid or gas to flow in one direction only. The valve works by using a disc or ball that opens and closes with the flow of fluid or gas. When the fluid or gas flows in the correct direction, the valve opens, allowing it to pass through. However, when the flow reverses, the disc or ball is pushed back against the valve seat, sealing the valve and preventing the fluid or gas from flowing back.

What is a Check Valve

What is a Check Valve

A check valve, also known as a non-return valve or one-way valve, is a mechanical device that allows fluid or gas to flow in only one direction. It prevents backflow or reverse flow of the fluid or gas, ensuring that it flows in the intended direction. Check valves are commonly used in piping systems, pumps, compressors, and other mechanical systems to prevent damage and ensure proper operation. Working of Check Valves A check valve is a type of valve that allows fluid or gas to flow in one direction only. It is designed to prevent backflow or reverse flow of the fluid or gas. The valve opens automatically when the fluid or gas flows in the correct direction and closes when there is backflow or reverse flow. Check valves are commonly used in plumbing, heating, ventilation, and air conditioning systems, as well as in industrial and manufacturing applications.

So what are the common uses of ball valves?

So what are the common uses of ball valves?

Usually, ball valves are recommended for pipeline systems with dual adjustment, strict sealing performance, mud, wear, necking channels, rapid opening and closing action (1/4 turn opening and closing), high pressure cutoff (high pressure difference), low noise, air pockets and gasification phenomena, small leakage to the atmosphere, low operating torque, and low fluid resistance.

Principle of Electric Stop Valve Working Principle of Electric Stop Valve

Principle of Electric Stop Valve Working Principle of Electric Stop Valve

The closing principle of electric globe valves is to rely on electric thrust to rotate the valve stem, making the sealing surface of the valve disc and valve seat tightly fit, preventing medium flow. Electric shut-off valves only allow one-way flow of media and have directional installation. The structural length of the shut-off valve is larger than that of the gate valve, and the fluid resistance is high. Therefore, the sealing reliability is not strong during long-term operation.
