in order to make the flange plunger pneumatic valve installation is more simple, need to do?
flange plunger design and manufacture of pneumatic valve is designed to solve common by the flaws of the pneumatic valve, general by the pneumatic valve seal USES grey root packing, cannot be ruled out leakage phenomenon, sealed by the pneumatic valve with pneumatic valve body under plane Angle or seal ( Metal seal) The sealing leakage caused by the wear between the metal, and maintenance difficulties; Plunger structure characteristics of the pneumatic valve is made up of a stainless steel plunger, up and down two elastic sealing ring and a metal frame, the plunger seal and seal closely cooperate to achieve, plunger in the two sealing ring, sealing area is greater than the average stop pneumatic valve; Switch pneumatic valve, plunger piston to move slowly in the sealing ring, interface is almost no wear and closed, under the plunger insert seal, truncation port; Open, plunger, though out of the sealing ring, but it is still hidden in the sealing ring, keep the isolation with the outside world, without leakage. Sealing ring is science and technology products, is the key to the piston pneumatic valve parts, it is composed of ptfe, graphite, high elastic rubber and so on, by the reciprocating motion test one million times, still can provide good sealing performance. Pneumatic valve small open torque, at the same time sealing area is large, wide applicable medium, to adapt to the high temperature and reliable sealing, long service life, convenient maintenance, etc. Widely used in petroleum, chemical, electric power, pharmaceutical, food, textile, printing and dyeing, boiler, mechanical and other industries.
when the pneumatic valve cover nut have what can't eliminate the phenomenon of leakage, maintenance, maintenance will need to change the sealing ring. Here 'replacement' will not leak of the plunger pneumatic valve pneumatic valve from the line separating down, but the new seal to replace the old sealing ring. This program without special equipment or technical personnel. Every skilled workers all have no difficulty (in) replace the sealing ring, in order to more convenient installation work, we provide a simple set of tools - The lantern type, , seals extractor and the frame, the specific steps are as follows:
, to cut off the upstream fluid, make unattended pneumatic valve ( Hereinafter referred to as there will be no fluid flows through the pneumatic valve, pneumatic valve open, All open;
and remove the nut, spinning wheel in the direction of the closure, the pneumatic valve cover out;
, pneumatic valve cover screw holes from the stud, the pneumatic valve cover around the pneumatic valve rod turning a small Angle, make the pneumatic valve cover flange bottom face the stud bolt head;
by rotating the handwheel, reverse direction, let the pneumatic valve cover on the stud, continue to turn the handwheel until plunger josephalbert on sealing ring;
