Good Wholesale VendorsGate Valve Cad Drawings - slowly closing flange check valve – Jinbin Valve Detail:
slowly closing flange check valve
The check valve is mainly composed of valve body, two semicircular valve discs, return spring, oil storage cylinder, slow closing small cylinder bank Needle valve (micro regulating valve), which pushes the two valve discs smoothly by the thrust of the inlet medium. At the same time, the pressure medium at the inlet enters the lower part of the piston in the oil storage cylinder to push the piston, and the oil at the upper part of the piston is respectively pressed into the tail end of the small cylinder on both sides of the valve body through the needle valve, so as to extend the piston rod in the small cylinder. When the pressure of the inlet medium drops below the pressure at the outlet At this time, the disc will close automatically under the action of spring and medium return, but because the piston rod is in the extended position. The valve disc can not be fully closed against it, and about 20% of the area is left for the medium to pass through, which plays the role of hammer elimination.
