Zhengzhou source of the pressure relief valve to find source of ore with a pressure relief valve producing coal with a pressure relief valve Supply

 Zhengzhou source of pressure relief valve pressure relief valve Sell Coal power source http://www.zzlydz.com ZHENG Ying allowing you greater ease pressure relief valve supplied with coal mine. Contact 037,168,012,805.13633843787 Zhengzhou Li Electronics Co., Ltd. is located in Henan Province, Zhengzhou High-tech Industrial Development Zone, is a collection of power plants, mining machinery and electronics research and development, manufacturing, sales and service in one of technology-intensive enterprises. With many domestic research institutions and business groups to establish a fixed strategic partnership, the company has an experienced professional research team composed of senior engineers. It has strong product development, transformation and production capacity. Zhengzhou Coal source of the pressure relief valve to find source of supply with a pressure relief valve pressure relief valve for use in mines supply, http: Action must be equipped with reliable safety valve and drain valve on //www.hnlydz.com air bag, and there are inspection holes must be periodically remove grease air package. The new installation or maintenance of the air bag after the application of 1.5 times the working pressure air compressor to do the hydrostatic test. In the air bag discharge piping must be installed pressure relief valve, pressure relief valve diameter shall not be less than the diameter of the outlet tube to release the pressure of the air compressor should be the maximum working pressure of 1.25-1.4 times. Mine air bag pressure relief valve from the cylinder, piston assembly, protective cover and other components, cylinder by the left and right end flanges and welded cylinder block group, in order to enhance the wear resistance and prevent rust cylinder made of stainless steel. Piston group consists of cardboard, O-rings, piston rod and the like. Piston assembly from the cylinder can be loaded via the card board on the left and the piston assembly is fixed in the cylinder, so that it can not move around. Protective cover from the flange, the cylinder and welded door group. When releasing the pressure relief valve, a protective cover prevents piston flying out assault, play a security role. Pressure relief valve installed in the air compressor system package export pipeline stroke is on the air flow direction, when the air compressor system is working properly, the system pressure ≤0.785 (8kgf / cm2) MPa, under this pressure, the release of the valve is working properly. When the air bag due to soot fire or for some reason within the air bag gas explosion, the system temperature, pressure transient increases, when the pressure was raised to 1.03 ± 0.049MPa (10.5 ± 0.5kgf / cm2), the rod immediately pull off, release the pressure relief valve, air bag and piping hot, high pressure gas to the rapid release, which play blast mitigation, to avoid accidents role. Usage air bag pressure relief valve for ground or underground air compressor systems, air bag installed in the outlet pipe is on the air flow direction, diameter pressure relief valve shall not be less than the diameter of the duct, the compressed air pressure should be released 1.2-1.4 times the maximum working pressure of the machine, from the security role. Zhengzhou Coal power source pressure relief valve pressure relief valve supply allows you to find the source of the ZHENG Ying greater ease with pressure relief valve supply coal mine.
