Check Valve is a valve used to control the flow direction of pipeline fluid, also known as non-return valve, reverse valve, reverse flow valve, etc. Its main function is to prevent the backflow of fluid in the pipeline, avoid equipment damage, fluid pollution and other problems, and at the same time ensure the safe operation of the pipeline system. The working principle is to use the valve disc inside the valve. When the fluid enters the pipeline from one side, the valve disc will open to allow the fluid to flow smoothly; and when the fluid enters from the other side, the valve disc will close to prevent the fluid from flowing backward. Therefore, check valves generally only allow one-way flow and cannot reverse flow.
There are many types of check valves, mainly gate check valves, ball check valves, ferrule check valves, swing check valves, etc. Among them, the gate check valve is the most common one, which is simple in structure and easy to use, and is suitable for various pipeline systems. The ball check valve has the advantages of good sealing and small fluid resistance, and is suitable for pipeline systems under special conditions such as high pressure, high temperature, and high viscosity. The installation position of Check Valve is also very important, usually it should be installed at the outlet of the pipeline or the inlet of the pump to ensure its normal operation. In addition, the maintenance of the check valve is also very important, and it should be cleaned, inspected and lubricated regularly to ensure its normal operation. In short, the check valve plays a very important role in the pipeline system. It can ensure the safe and stable operation of the pipeline system and avoid many unnecessary losses and risks. Therefore, when designing and maintaining the piping system, the use and installation of check valves should be fully considered. We have Car Antenna on sale, if you need it, please contact us.
