Double gate valves - principle-Mech Valve

by:Mech     2020-04-09

double gate valve working principle: the outside of the cylinder or the handwheel to provide power, with the help of the stem drive disc up and down movement, open and close the valve. In the process of the valve opening and closing, spring pre-tightening force between double ram is close contact between the valve plate and valve seat, so as to realize seal. Among them, the pneumatic ceramic double gate valve working principle is: when the air from the entrance into gas gate valve stem drive valve plate down, the valve closed. When the air from a low entrance into the stem drive disc moving up, open the valve. Spring load between the valve plate and valve seat, spring always make the disc to seat pressure, to ensure that the valve seat seal, and allows the valve plate moves up and down vertically, it helps to compensate thermal expansion and contraction of the valve components, can overcome the effects of any change of back pressure to seal and prevent particulate medium into two density between the valve cover. In the process of opening and closing, the valve plate will produce rotation, and between the sealing surface grinding and polishing, and because of the eccentric valve body in the channel, produce eddy current, when open the discharge material and discharge material vortex will clean the inner cavity of valve itself. All of these features make the valve has a long service life and safe operation for your system provides a reliable guarantee. Valve plate and valve seat adopt toughening of engineering ceramic material, has excellent resistance to erosion and abrasion resistance. Between two brake plate, there is a spring through two-way flexible spring preload pressure since the tight seal, the seal has the characteristics of low pressure double sealing, no blockage and ash accumulation in the process of opening and closing. In the process of the valve opening and closing, uniform rotation valve plate and valve seat, sealed performance is lasting, in the process of open and close frequently, dry powder medium sealing surface wear uniform, high sealing performance, long service life. Body of channel for eccentric design, when open the drainage valve plate material, material spiral vortex generates substances, materials of vortex will plug valve body cavity cleaning materials, in addition there will be blowing mouth, can be used to remove dust and through external gas source maintenance valve valve.
