- pneumatic ball valve Aerodynamic lift check valve according to its structure and installation method of classification

and aerodynamic lift check valve pneumatic valve disc, pneumatic seat around the tunnel axis of rotation movement, as in the pneumatic valve passage into a streamlined, flow resistance is smaller than l butterfly check pneumatic valve, suitable for low flow velocity and flow not often change the large diameter of occasions, but should not be used for oscillating flow, its sealing performance than lift. Pneumatic valve butterfly check points, single type, double disc type and mostly type three, the three forms mainly by the pneumatic valve diameter, the purpose is to prevent the backflow medium flow or stop, decrease hydraulic shock. , aerodynamic lift check valve, pneumatic valve pneumatic valve body along the vertical centerline sliding check pneumatic valve, internal thread check pneumatic valve can only be installed in horizontal pipe runs with the high pressure small check pneumatic valve pneumatic valve can be used on the ball. Butterfly check pneumatic valve pneumatic valve body shape as well as by the pneumatic valve ( To stop pneumatic valve general) Fluid resistance coefficient is larger, so it. Its structure is similar to stop pneumatic valve, pneumatic valve body and disc is the same as the cut-off pneumatic valve. Pneumatic valve upper part and lower part of the pneumatic valve cover processing has a guide sleeve, Jane Jane pneumatic disc guide can be freely within the pneumatic valve light guide Jane, when medium downstream, pneumatic disc by medium thrust open, when stop the flow of medium, landing on the hanging in the pneumatic pneumatic valve seat valve, prevent medium counter-current role. Straight-through butterfly check pneumatic valve medium import and export channel direction and pneumatic seat vertical direction; Vertical lift check pneumatic valve, its media channel direction and pneumatic valve seat in the same direction of imports and exports, its a straight-through flow resistance is small. , aerodynamic lift check valve, pneumatic disc around a pneumatic seat within the pin shaft rotation check pneumatic valve. Butterfly check pneumatic valve has simple structure, can only be installed in horizontal pipe runs, sealing is good. Pneumatic valve and lift check: pneumatic disc sliding along the center line of the pneumatic valve pneumatic valve. Pipeline check pneumatic valve is a new kind of pneumatic valve and its small size, light in weight and good fabrication procedure, check the pneumatic valve is one of development direction. But fluid resistance coefficient than the swing check valve is slightly larger. , compact type check pneumatic valve: this kind of pneumatic valve is used as boiler feed water and steam to cut off the pneumatic valve, it can lift check pneumatic valve pneumatic valve and globe or Angle valve of comprehensive function. In addition, there is - Some is not suitable for pump discharge installation check pneumatic valve, such as hand valve, spring loaded, Y type check pneumatic valve, etc. YAZE( Pneumatic company's main products: pneumatic pneumatic valve pneumatic ball valve pneumatic butterfly valve Keywords: pneumatic pneumatic valve pneumatic pneumatic valve
