Pneumatic valve and manual flashboard electric flashboard pneumatic valve

manual flashboard pneumatic valve is also called the manual brake pneumatic valve and manual spiral plate pneumatic valve.
manual flashboard pneumatic valve features:
. Manual flashboard pneumatic valve with discharging device or bin, manual spiral gate pneumatic valve with flange connection, easy to install in and out of the mouth has two kinds of square and circular, there are dozens of specifications, according to the size of the diameter is widely used in metallurgy, carbon, chemical industry, building materials, etc.
. Manual flashboard pneumatic valve has simple and compact structure, reasonable design, reliable seal, flexible operation of the light, small volume, smooth channel, small resistance and easy to install, easy to remove, manual spiral gate pneumatic valve can be installed horizontally or vertically, wear resistant and automatic compensation function characteristics of long service life.
. Manual flashboard pneumatic valve in the normal use of each part should be checked regularly, in the process of lubricating maintenance.
electric flashboard and matters needing attention in using pneumatic valve and its characteristic: the board of the pneumatic valve opening and closing is ram, ram movement direction perpendicular to the direction of flow and the flashboard pneumatic valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used model of pneumatic valve gate sealing surface form a wedge, the wedge Angle vary with parameters of pneumatic valve, usually, wedge flashboard pneumatic valve disc can be made into a whole, is called a rigid disc; Can also make it generates 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 flashboard pneumatic valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the pneumatic valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most flashboard is forced sealing pneumatic valve, pneumatic valve closing, namely to rely on outside force forced the ram pressure to the pneumatic valve seat, to ensure the sealing surface sealing. Flashboard pneumatic valve seal structure can be soft seal and hard seal structure.
