The structure characteristics of pneumatic valve flange track ball

flange rail pneumatic ball valve is to use pneumatic valve electric actuator control, so as to realize the pneumatic valve is opened and closed. It can be divided into fluctuation two parts, the first half of the pneumatic valve flange orbit ball for electric actuator, the lower part of the moment than electric pneumatic valve, pneumatic valve action flange rail pneumatic valve switch ball speed can be adjusted, simple structure, easy maintenance, action for buffer characteristics of the gas itself in the process, not easy to damage due to get stuck, but must have a gas source, and the flange rail pneumatic ball valve control system is more complicated than the electric pneumatic valve.
(1) the flange track pneumatic ball valve adopts pressure self-tightening seal or pneumatic valve, pneumatic valve cover gasket sealing structure, reliable! The use of safe and reliable.
2. Flange rail pneumatic valve pneumatic ball valve adopts double ram with universal structure, can automatically adjust the pneumatic valve with pneumatic valve seat sealing surface alignment, to ensure that the pneumatic valve seal. At the same time, the structure, convenient maintenance, saving cost, pneumatic disc replacement is better.
3. Flange orbit pneumatic valve pneumatic ball valve, pneumatic valve seat sealing surface with chromium cobalt tungsten carbide by plasma spray welding, sealing surface hardness, friction resistance, abrasion resistance, long service life.
(4) the flange orbit pneumatic valve pneumatic ball valve rod with nitriding steel, surface nitriding treatment, high hardness, abrasion resistance, corrosion resistance, long service life.
5. Flange rail pneumatic ball valve electric device is equipped with a torque control mechanism, the site operation institutions and hand, electric switching mechanism. In addition to on-site operation, but also can carry out remote operation, PLC control, intelligent control ~ mA current input and output, etc.
6 manual pneumatic valve by manual or impact handwheel. Reduce the flange track pneumatic ball valve operating force.
7 flange rail pneumatic ball valves can be installed in any position, at the same time, choose according to the temperature of the medium and medium carbon steel or alloy steel pneumatic valves.
end installation and debugging for the first time, you have to manually put the flange rail pneumatic ball valve open to about half of the position, so as to avoid the motor phase sequence after the result in pneumatic or electric valve damage.
flange rail pneumatic ball valve can be made to produce trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, the gate is called elastic disc most pneumatic type knife gate valve is sealed with mandatory, namely the pneumatic valve is closed, to rely on outside force forced the ram pressure to the pneumatic seat, to ensure the sealing of sealing face this kind of pneumatic valves shall generally be installed in the pipeline.
flange rail pneumatic ball valve has simple and compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, can be in work pressure. MPa - 。 MPa, the use of temperature - - ℃ cases, normal work. Flange rail pneumatic ball valve gate with shear function, and can shave their seal adhesive on the surface of the object, automatically removing debris, pneumatic valve flange orbit ball stainless steel gate to prevent seal leakage caused by corrosion.
