overview MQAF pneumatic discharge ball valve:
MQAF pneumatic discharge ball valve is a new generation of high-performance pneumatic ball valve, suitable for long distance pipeline and general industrial pipeline, its strength, security, and resistance to bad environment, special consideration when the design is suitable for all kinds of corrosive and non corrosive medium. Compared with the floating ball pneumatic valve, it works, pneumatic valve fluid pressure on the ball before all is passed to the bearing force, will not make a sphere to the mobile pneumatic valve seat, and pneumatic seat deformation is small, stable sealing performance, long service life, applicable to high pressure, large diameter. Advanced springs in pneumatic seat components, since the tight characteristics, realize the upstream sealing. Each pneumatic valve has two pneumatic valve seat, each direction can be sealed and installed without flow limit, is two-way. This pneumatic valve has two and three pieces of two kinds of pneumatic valve body structure, the flange bolting, seal enhanced ptfe inserted into the stainless steel ring, steel ring is equipped with a spring at the back of the guarantee pneumatic seat close to the ball, keep the seal. Pneumatic valve stem up and down with PTFE bearing, reduce friction, easy operation, small at the bottom of the shaft adjustment, to ensure that the ball and seal it. Adopt the structure of the full size of pneumatic valve flow hole is consistent with the pipeline diameter, so that pipeline cleaning.
MQAF pneumatic discharge ball valve features and advantages:
and manual part of the steel plate can be used to neutralize the grip or the handle of the stainless steel casting. Handle sets limit structure, set in the position of the pneumatic valves open and close limit, when the pneumatic valve used in the key device, limit block has a lock can lock switch position to avoid wrong operation. Handle has obviously and off.
and pneumatic valve stem adopts AF ( Cr） Overall forging and modulation treatment, hardness of HB ~. Pneumatic valve rod through key spline or the parties connected to the handle, strong commonality, easy tear open outfit. Pneumatic stem with blow-out proof design.
, pneumatic valve filling knitting, flexible graphite sealing ring or ptfe sealing ring, lubricated pneumatic valve stem in certain circumstances to achieve reliable seal.
, sealing deputy various forms. According to the different condition can choose soft seal and hard seal, fire prevention structure such as pneumatic valve seat; Below DN for floating ball form, the DN for fixed ball form below.
, pneumatic ball valve pneumatic seat in auxiliary seal structure can be set up, in the pneumatic seat and pneumatic valve stem parts adding greasing pneumatic valve, an emergency can be temporarily seal, and can according to need to lengthen the pneumatic valve stem with suitable buried laying venues.
