With the development of science and technology in our country and the people's livelihood, in recent years, Q41Y - 160 c stainless steel ball Industrial Valves not only influence on industrial sectors in expanding gradually, Q41Y - 160 c stainless steel ball valve in the field of civil awareness is gradually promoted. Today in wenzhou with constant pneumatic belt you know Q41Y - stainless steel ball valve manufacturer 160 stainless steel ball valve c application conditions and operation. Q41Y - 160 stainless steel ball valve installation points 1 c. Installation location, altitude, direction must be consistent with the design requirements of imports and exports, meticulous and medium flow direction should be equal to the body the direction of the arrow, the connection should be firmly connected. 2. Surface inspection must be conducted before installation of valve, Q41Y - 160 c stainless steel ball valve of the valve nameplate should be consistent with existing national standards 'universal signal valve' regulation. For the working pressure is greater than 1. 0 MPa and cutting effect on backbone pipe valves, strength and precision performance test should be done before the installation, qualified rear must use. Strength test, the test pressure for the nominal pressure of 1. 5 times, duration of not less than 5 min keywords ranking, shell and packing shall be no leakage of valve shall be qualified. Precision test, the test pressure for the nominal pressure of 1. 1 times; The duration of the test match requirements. 1) Q41Y - 160 c stainless steel ball valve has two floating seat, each Q41Y - 160 c stainless steel ball valve seat are designed as two of the flow direction of medium can seal, therefore Q41Y - 160 c stainless steel ball valve not only can realize two-way sealed and can realize the import and export seal at the same time, the seat is 'O' type sealing ring seal and spring pre-tightening force of floating seat structure, when Q41Y - 160 stainless steel ball valve thermal expansion valve and cause c midplane pressure is greater than the pressure of the pipeline, in Q41Y - medium 160 c the pressure difference on both sides of the stainless steel ball valve seat will push the floating seat away from the gate, the midplane pressure through the clearance between the disc and seat leakage in pipeline, thus useful cherish Q41Y - Safety of 160 stainless steel ball valve valve c, and the structure of the open-close torque for popular valve 1/2, can achieve easily open and close the valve. 2) Q41Y - 160 c stainless steel ball valve seat is Mosaic PTFE seal face, with PTFE to metal and metal to metal seal, PTFE sealing surface and clear in addition to the role of the ram. Metal to metal hard seal have extremely strong sealing, scouring resistance, pipeline with a variety of suspended particles in the medium, no any impact to seal, ensure no leakage of creating a website, can fully compensate the wear of seal face actively, Q41Y - at high temperature 160 c stainless steel ball valve gate will not be stuck due to expansion, and is applicable to often switch places. 3,) Q41Y - 160 c on the stainless steel ball Industrial Valves body and cover design are fat injection valve, sealing grease by Q41Y - 160 c stainless steel ball Industrial Valves seat sealing surface on the valves can enter on body, auxiliary sealing effect, and more reliable sealing, zero leakage and sealing grease on the valve cover on the valve can be packing spacer ring into auxiliary sealing effect between stem and packing, reliable sealing to zero.
