5, application
High pressure polyethylene pipe should be set on the charge of sub-polyethylene valve and the valve should be on both sides of the elution tube. High pressure polyethylene gas pipe branch should be set at the starting point of polyethylene valves, set the diffuse unilateral control. PE ball valve is mainly density polyethylene pipe buried in the package, cut off all gas transmission and media streaming. The valve can be buried in the ground, just install a simple sheath, opening and closing seat accessories, you can use a special wrench to perform opening and closing operations on the ground, polyethylene ball valve for the media to meet the national standard gas purification , liquefied petroleum gas and artificial gas.
6 Conclusions
PE ball valve opening and closing of the torque, the valve no corrosion, no maintenance and repair, the service life of 50 years to improve the integrity of polyethylene pipe network system. The overall style of the body, eliminating the possibility of leakage, polyethylene, polyethylene pipe connected with the ball, no need to set the valve shaft, buried construction, the body can use the butt end of pipe welding method of welding or electrical connections, valves, The opening and closing operations on the ground than the overall economic efficiency of conventional metal ball about 2 times higher. Polyethylene pipe with excellent performance, with the polyethylene material for further research and development, polyethylene pipes and valves have better applications.
