The method of techniques to enhance type plug

Enhance type plug has a variety of structural forms, enhance type plug according to the sealing surface of the material is divided into two kinds of soft seal and hard seal. The basic principle is to open up the cock, cocks and then turn 90 degrees to the process valve is fully open and valve sealing surface to reduce friction; close the valve when the cock is rotated by 90 degrees to the closed position and then decreased with body seal surface contact to Plastic seal.
1, double sealed to enhance type plug
Double sealed to enhance type plug with soft sealing structure. Cock body is a combination of three panels cylindrical plug body, set on both sides of the rubber plate sealing surface, the intermediate cylindrical wedge plug.
Open the valve actuator to make cocks rise, driven by both sides of the plate collapsed, and the combination of the plug body from the valve sealing surface, then drive plug body is rotated 90 degrees to the valve fully open position.
Close the valve drive mechanism so that rotation of the plug body 90 degrees portfolio to the closed position, and then push down the plug body, both sides of the plate is no longer in contact with the bottom of the body down the middle wedge plugs continue to decline, pushing through the beveled side plates mobile phase inlet and outlet, so that side of the soft sealing surface in contact with the valve sealing surface is compressed to numbered seals.
Double sealed to enhance type plug has dual obstruction and discharge function, the valve has a pressure balance device, to prevent abnormal pressure system, and can reduce the valve opening and closing moments of resistance. Since the metal surface after sealing ring is compressed in contact with each other, the valve has a fire safety features. Very convenient maintenance of the valve, the valve body can be made without removing the case from the pipeline, the bottom of the cap body by removing the side panels can be removed from the body replacement. It is also widely used in petroleum, natural gas, metallurgy, mining, gas engineering, textile, marine terminals, food, and water treatment and other industries to make adjustments, opening and closing the pipeline fluid use.
