The one-way valve is also called a check valve, its function is to prevent the back flow of the medium in the pipeline. The bottom valve that shuts off the pump is also a type of check valve. The valve that starts and closes is automatically opened or closed depending on the flow and force of the medium to prevent the medium from flowing back is called a check valve.


This check valve is an automatic valve, which is mainly used in pipelines where the medium flows in one direction. In order to prevent accidents, the medium is only allowed to flow in one direction. Under normal circumstances, the fluid opens the disc of the valve under pressure and flows from the inlet end to the outlet end. When the inlet side pressure is lower than the outlet side, the valve flap automatically closes the passage, so that the passage is not affected by the fluid pressure and its own gravity, and prevents the inlet gas solenoid valve from flowing backward. According to the movement mode of the disc, check valves are mainly divided into three types: lift type, swing type and butterfly type.


The valve body of the lift check valve is mostly similar to the stop valve body, and the fluid resistance of the imported high-pressure solenoid valve is relatively large. This kind of check valve is a high-pressure small-diameter, usually a spherical valve disc.


The swing check valve has a small resistance to fluid, and is generally suitable for small and medium-sized, low-pressure, large-diameter pipelines. Often multiple valve flaps are arranged on the valve channel partition to become a multi-leaf type.


The butterfly check valve has a similar shape to the butterfly valve. The device has a simple structure and low resistance. If the check valve is closed too fast, it may cause liquid shock in the liquid pipeline, generate noise, and even damage the valve components. In order to avoid this situation, a check valve with buffer function can be selected as needed to extend its closing time.


In a nutshell, by installing a check valve, you can control the flow of the medium in the multi-channel pipeline of the steam solenoid valve manufacturer, and develop in the direction you want.
