A check valve is a check valve, and a check valve is only a one-way opening and closing valve that prevents the backflow of the fluid medium on various pipelines or equipment. Check valves are now widely used, and there are many types. The following is a check valve commonly used in water supply and heat:
1. Spring type: The liquid moves from bottom to top, and the spring-controlled valve flap can be lifted up by pressure. After the pressure disappears, the spring force will press down the valve flap to seal the backflow of the liquid. Often used for small diameter check valves.
2. Gravity type: Similar to the spring type, it is closed by the self-gravity of the valve disc to prevent backflow.
3. Swing type: The liquid flows straight through the valve body, and the rotary valve flap on one side is opened by the pressure. After the pressure is lost, the valve flap returns to its position by its own weight, and the reverse liquid pressure closes the valve flap. Other one-way valves (check valves), such as sewage check valves, civil air defense explosion-proof valves and liquid check valves, have similar principles.
