Internal thread plunger pneumatic valve is introduced

product name: threaded piston pneumatic valve inside the
the characteristics: the female connection plunger non-metallic sealing pneumatic valve points, two types of metal seal, in addition, the external thread connection plunger pneumatic valve its appearance is divided into two major categories of zigzag and drum-shaped, its internal structure are exactly the same, USES, mainly used in metallurgy, electric power, chemical industry, oil refining, food and other industries. Pressure for - KGF/cm, temperature ℃ for the following on the small-bore pipe such as water, steam, oil for opening and closing flow adjustment.
plunger pneumatic valve are our combined with domestic actual research and development, its design and manufacture is in order to solve the ordinary 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 pneumatic valve is closed by a stainless steel plunger, up and down two elastic sealing ring and a metal frame, sealing effect by the plunger 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.
