The hydraulic check what are the technical requirements

What are the technical requirements for hydraulic check valve? Hydraulic check valve wider range of application, and the performance of the rapid development of science and technology make it enhances unceasingly, for steam turbine, the contribution is very big, is used in order to prevent the extraction steam pipeline flow backward or accident cases. Because once flow backward, causes the steam turbine speed, it is very dangerous. 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 quick closing check valve structure characteristics of 0. 1, fast closing time 5 ~ 1 second, emergency cut-off safe and reliable. 2, valve plate by closing thrust, achieve the goal of the globe, check. 3, the valve plate adopts large Angle, 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) 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.
