New rapid close dome pneumatic valve pneumatic valve

dome pneumatic valve is a new type of quick closing valves, it USES the international most advanced air seal type structure, pneumatic valve open/close the pneumatic valve core and no contact between inflatable sealing ring round, seal USES a specially formulated rubber, seal, powder materials can be widely used in gas cap is pneumatic valve is a new type of quick closing valves, it USES the international most advanced air seal type structure, pneumatic valve open/close the pneumatic valve core and the key parts of rechargeable power transmission system, is widely used in electric power, metallurgy, chemical industry, food, pharmaceutical and other fields. Working principle of the

dome pneumatic valve pneumatic valve core is a spherical dome, dome pneumatic valve in the process of switch, pneumatic valve core and keep some mm gap between the rubber sealing ring, pneumatic valve core and the rubber sealing ring can be in the form of contactless movement, the purpose is to make the pneumatic valve core and does not produce friction between the rubber sealing ring, reduce wear and tear. Dome of the pneumatic valve pneumatic actuators for full sealed linear or fan cylinder, direct drive dome pneumatic valve, effectively prevent the dust into the wear and leakage phenomenon. When dome pneumatic valve closed, rubber seal aeration, expansion, holding pressure on the spherical dome pneumatic valve core, thus forming a very reliable sealing ring belt, blocked the flow of the material in the pipeline.
dome pneumatic valve pneumatic valve core according to different occasions, different materials, different surface hardening treatment, the use of pneumatic valve core is smooth and hard surface, ensures good close contact with the rubber sealing ring, in order to ensure reliable sealing. Rubber seal adopts special rubber, high temperature resistance, corrosion resistance, wear resistance, aging resistance and other characteristics, long service life. The pneumatic valve opens, mouth full circulation without stop. The pneumatic valve is suitable for gas, liquid and semiliquid, solid powder material, etc. Attention

rubber seal pressure should guarantee in air. — 。 MPa and higher than the delivery pressure. MPa, cylinder pressure. — 。 MPa, the use of clean, dry, oil-free compressed air.
installation, use points
, read this manual carefully before installation, check and pneumatic valve type, size and technical parameters.
strictly prohibit the welds with the pneumatic valve flange, so as not to damage the pneumatic valve seal. Tube reserved pneumatic valve installation distance should be appropriate, on both sides of the flange gasket.
, two pipe center center should maintain coaxial with the pneumatic valve size and flange face should level off, do not allow the large deflection of the flange surface, to guarantee the normal work of the pneumatic clamping and valve. Tighten bolts should be uniform.
before delivery, the pneumatic valve has been adjusted and dynamic test, pneumatic connection intact.
