Corrugated pipe pneumatic valve use items

corrugated pipe pneumatic valve principle:
the principle of corrugated pipe pneumatic valve is in the general pneumatic valve sealing element with a corrugated pipe, the bottom and pneumatic valve adopts automatic seam welding welding, the upper roll and connection plate automatic welding, between the fluid and the atmosphere to form a metal barrier, to ensure that the pneumatic valve stem zero leakage. Bellows type is very much also, pneumatic valve using corrugated pipe mainly adopts metal corrugated pipe, its stress corrosion resistance performance is good, long service life, can keep the characteristics of long time without leakage. Stage I make corrugated pipe pneumatic valve is mainly used in corrosive or requiring zero leakage of poisonous gas, liquid used as on-off or adjust flow.
corrugated pipe pneumatic valve using range:
common corrugated pipe pneumatic valves are mainly pneumatic valve, corrugated pipe gate pneumatic bellows globe valve and pneumatic valve, corrugated pipe to adjust by the pneumatic valve and gate valve is suitable for use as on and off, and regulate the use of pneumatic valve is used to adjust flow. I factory production of corrugated pipe pneumatic valves conform to the standard GB, DIN, API, applicable to steam, heat conduction oil, highly toxic, strong corrosion gas and liquid medium, working pressure PN. ~ MPa, the working temperature ~ ℃ of petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, all kinds of working conditions, such as cut or flow control.
corrugated pipe pneumatic valve used items:
corrugated pipe is usually used in high vacuum pneumatic valve and requiring zero leakage of medium. In strong chemicals corrosion, can use double bellows seal, seal, two layer of protective film. For working condition of the use of more frequent occasions may purchase more of corrugated pipe, such as found in the air with medium flavor or pneumatic valve by the damp, the general is a corrugated pipe were broken in medium, can be accompanied by the mechanic to replace corrugated pipe, avoid the negligence of a long period of time, as the threat of life and the whole pneumatic valve damaged in pairs. Conditions requiring high import bellows can choose to replace, we can offer the German imports of corrugated pipe, the price is reasonable, the products comply with gb standard, German standard, American standard requirements.
corrugated pipe pneumatic valve features:
, use a metal corrugated pipe material, its stress corrosion resistance is strong;
, double or multiple seal design, if corrugated pipe damage, packing also can compare medium to large leaks;
, bellows, reduce energy losses, improve the mechanical equipment safety;
high performance/price ratio, and pneumatic valve life after the more corrugated pipe can be pneumatic valve two to three times higher than normal;
, medium special occasions without artificial take care;
, high temperature occasion, pneumatic valve seat adopt hard seal cone, achieve zero leakage airtight performance.
