4 pneumatic tire union pneumatic tire in inflated or deflated, the cap should be put on gas nozzle to avoid damage to the gas nozzle. 5 pneumatic tire loaded or unloaded steel, should be to protect the gas nozzle to avoid damage to the threaded gas nozzle, affecting. 6 In order to seal reliable pneumatic tire inflation pressure may be greater than line pressure 0.3mpa. 7 when the pipeline needs to be removed, you can first remove the gas nozzle the cap, and then a thin stick the gas nozzle inside the valve to open the top, you can put gas relief . After thorough relief within 1-4 seconds, the pneumatic tire can be automatically restored to the original diameter size so pipe can be freely withdrawn from the pneumatic tire. 8 steel insert gas Taiqian, pneumatic tires should be completely depressurized will be smaller than the inner diameter of the air tube or pipe diameter and can not be inserted. 9 To protect the air tube, pipe ends should not be less than 15 degrees chamfer pipe surface should be smooth, free of burrs or pits. Two pneumatic tire 10 by a connecting line between Wang may be steel, glass pipe, it may also be at both ends of the hose-end connector 11 of our San Di Machinery Factory production of oil with gas hose connector fitting tire unions can use good fast implementation slurry tanks or piping misalignment installation and sealing. Pneumatic tire union Description: Suitable for large diameter, low pressure, medium and large diameter pipe disassembly frequent connections. In particular, various water purification pipeline connecting pipeline system and medium caliber among the paste pot connections for petroleum drilling operations. Advantages: 1) installation demand low, can not achieve rapid installation and sealing tire inflated to the gas that is reliable seal does not leak. 2) pneumatic tire deflated, the pipeline to be pulled out, no tools, adaptable, simple maintenance. Shelf varieties: 4 "6" 8 "10" 12 "14" 16 "Medium: mud, oil, water, medium temperature: 0 ℃ -90 ℃ ambient temperature: -30 ℃ ~ 50 ℃ media pressure: 0. 5Mpa pneumatic tire inflation pressure: 0.4 ~ 0.8Mpa pneumatic tire deflated after the reset time: 1--4 seconds
