The structure characteristics of the hydraulic check valve is briefly

The structure characteristics of the hydraulic check valve is briefly? Hydraulic check valve innovation, now many industries are inseparable from it. But the main contribution is to the steam turbine, the biggest role is to prevent extraction steam pipeline flow backward or accident cases. Because once flow backward, causes the steam turbine speed, it is very dangerous. Hydraulic quick closing check valve structure characteristics 1, the valve plate adopts big bevel, shorten the open shutoff stroke, hydraulic ( Gas) Help achieve rapid opening and closing, three-dimensional eccentric sealing structure, open the seal separation, close contact with the sealing, lightweight flexible opening and closing. （ DN250 using cut-off or less) 2, fast closing time can reach 0. 5 ~ 1 second, emergency cut-off safe and reliable. 3, valve plate by closing thrust, achieve the goal of the globe, check. Wenzhou hydraulic quick closing check valve technical requirements 1. Hydraulic pressure source interface: RC1/22. The hydraulic cylinder operating pressure: 0. 5 - 0. 8 MPa3. Structure length: GB - 12221 894. The power supply voltage: AC220 - DC24V时( When you order it indicate) 5. Emergency cut-off time. 0. 5 - 6 1 SEC. Connecting flange: JB/T79 - 94 GB / 9113。 2000 hydraulic check valve manufacturer production services standardization hydraulic check valve factory productive service standardization, set up for the hydraulic check valve block industry services including service basic standards, service standards, service standards and other three standard system. Hydraulic check valve manufacturers carry out standard and related technical training services, and materials testing services for hydraulic control valves, valve standard information service, and has carried on the inspection on the implementation of the standards and improved, good results have been achieved after project implementation. By conducting hydraulic check valve standardization technical personnel training services, pneumatic control valve valve material and products inspection test service and standard information service and so on three services standardization work, prompting general valve hydraulic check valve production gradually to produce oil, petrochemical, natural gas and related industrial valves, to comprehensively promote industrial structure adjustment valve.
