Main structure characteristic and use:
This serial valves of subjects adopt and cast the structure of forging, have parallel pair seal pairs of half force two-way honeybee , seal piece put in place sport and Tenneco urgent sport function realize zero leak step by step.
The movement frictional force of sealed surface is little, it is light to open and close , and seal the surface and wear and tear and compensate the function automatically.
Of simple structure , compactness , overhauling conveniently, have long performance life.
Valve build packing room have vacuum sealed structure , have bloated function of compressing tightly since, and each connect every and adopt and excel in and expand materials to seal , make the system and atmosphere totally isolate, have very good systematic airtight.
This serial valves connect the form and divide the flange , weld two kinds, there are manual , electronic two kinds of drive ways.
Valve this suitable for working temperature 425 of ≤and ≤ 550, job for water , steam , at the road officer of air medium, especially suitable for shouldering the system of pressing in vapour machine condensation and vacuum of thermal power plant as opening and close the device , play a isolating sealedly in vacuum role.
