Hydraulic check valve product model classification?

Hydraulic check valve product model classification? Hydraulic check valve plate by closing thrust, achieve the goal of the globe, check. Products by using frequency is very high, not only be used by an industry, because it has many functions, so the use of more extensive, and the performance of the products in the development of science and technology driven, but I don't mean it at the time of installation and use can be simple operation, but should also be carried out in accordance with the formal instruction on! 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 innovation, now many industries are inseparable from it. But it is the main contribution is to steam turbine, a role is to prevent extraction steam pipeline flow backward or accident cases. Because once flow backward, causes the steam turbine speed, this is dangerous. Hydraulic check valve manufacturer for its introduction to the structure advantages of 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.
