Special pneumatic valves: new type of pressure from the advantage of smooth stop pneumatic valve 4
by:AIRWOLF2021-01-16
the main technical indexes of the pneumatic valve is as follows: nominal diameter DN -
Mm nominal pressure PN.
-
。
Mpa;
Applicable medium for water, steam, oil and other corrosive medium;
Suitable temperature ℃ or less;
Operating torque (
In order to DNmmPN.
Mpa as an example)
Nm radical products for Nm for high, medium pressure pipe has more obvious advantages.
Eliminated on the structure of the pneumatic valve design piping within the medium pressure on the influence of pneumatic valve, make the open-close part under medium pressure is still on the balance.
The pneumatic valve main characteristics are as follows: .
Moment of operation of the product just as radical as/pneumatic valve, pneumatic valve is widely used in the petroleum chemical industry, oil field, metallurgical and thermal power plant pressure piping.
Could be easily opening and closing without arm with pneumatic valve, pneumatic valve not only of the sealing surface is not easy to wear and tear, and won't cause of pneumatic valve flange sealing gaskets and connecting pieces of plastic deformation, greatly reduces the leakage and prolong the service life of the flange of the static seal, but also save a lot of pneumatic valve actuator, reduces the pneumatic valve.
can meet the industrial production, especially in thermal power plants, oil fields of more large diameter high pressure as the needs of the pneumatic valve.
。
For the same specifications different nominal pressure of the pneumatic valve, pneumatic valve stem handwheel and packing ring, the size of the parts are interchangeable, save material, and series production invented the favorable conditions for the product.
The pneumatic valve to change the current domestic production specifications can only be DN mm or less high pressure as the condition of pneumatic valve.
