What should be paid attention to using natural gas pipeline pneumatic valve?

the fuel gas is a new type of pneumatic valve gas pipeline engineering the safety of the supporting device; For truncation, connected, adjust the gas pipeline, has excellent control characteristic and closing sealing performance; Suitable for city gas, liquefied petroleum gas, natural gas, oxygen and other gas medium pipeline.

the use of natural gas pipeline pneumatic valves should pay attention to the following:
. For pipeline of natural gas contains a large amount of hydrogen sulfide (in front of the desulfurization This is a kind of strong toxic and corrosive gas. Even after the desulfurization process, such as natural gas, there are still residual hydrogen sulfide. So the pipeline pneumatic valve selection should choose sulfur corrosion resistance material.
。 The pneumatic valve for urban gas pipeline are over hundreds of kilometers, only regular patrols, inspection, and pipeline sometimes need through complex region, dielectric loss may bring serious fire accident. Especially in closer from the urban pipeline, it is particularly important to prevent pneumatic valve leakage.
。 Pipeline once put into operation, a few years are not allowed to stop running, not allowed to have a moment, no overhaul period. Tandem line of pneumatic valve in the line, once the failure consequence is unimaginable. So the pipeline pneumatic valve parts, requires a long life.
。 Typically in the station or control room, control requires control of the pneumatic valve with reliable performance, and require the pneumatic valve has its protection and explosion-proof measures. Especially long open of pneumatic valves, requirements in mutation, achieve accurate cutting. So it is key to reliable control performance.
