Zusammenfassung:	The utility model relates to a check valve with long service life. A valve cavity is composed of an upper valve body and a lower valve body. A one-way opening valve plate is arranged in the valve cavity. The valve plate is connected with the inside wall of the valve cavity by a single arm which is made of an elastic body. The utility model is characterized in that a crosspiece is arranged in the valve cavity which is arranged on the outlet side, and the crosspiece can support the opened valve plate. The utility model can effectively avoid vibration and swing of the valve plate caused by the instability of the water pressure, and reduce fatigue degree of the component. The service life of the utility model can extend more than three times. The work reliability of the application system is strengthened, and the work efficiency is improved.
