      • Ordering Process

      JY41W/Y oxygen cut-off valve is designed and manufactured according to the operation characteristics of oxygen pipeline network and the flammable and explosive characteristics of oxygen medium. It is designed and manufactured on the basis of safety, reliability and superior performance, and in accordance with the "Oxygen Safety Regulations" formulated by the Ministry of Metallurgical Industry of the People's Republic of China. Use the valve. The main material is stainless steel or copper alloy with excellent flame retardancy, the sealing surface is body or surfacing welding D802, the rest of the internal parts are stainless steel or copper alloy; the transmission part is lubricated with non-flammable grease and marked with obvious oil-prohibition mark. In structure, the bracket is totally enclosed, and has an electrostatic discharge device. The valve stem is equipped with a dust cap. The cut-off valve is adopted according to the regulations of the Ministry of metallurgical industry on the technical requirements of the oxygen network of iron and steel enterprises.


      The main material is stainless steel or copper alloy with excellent flame retardancy, the sealing surface is body or surfacing welding D802, the rest of the internal parts are stainless steel or copper alloy; the transmission part is lubricated with non-flammable grease and marked with obvious oil-prohibition mark.


      In structure, the bracket is totally enclosed, and has an electrostatic discharge device. The valve stem is equipped with a dust cap.


      Oxygen pipeline valves of Shanghai Qigao Valve Plant have been trusted by oxygen pipeline networks of major and medium-sized steel plants, oxygen plants and petrochemical plants since they were put on the market.


      Structural features of oxygen cut-off valve


      1. For nominal pressure PN (> 1.6 MPa), DNl25-200 adopts inner bypass structure; DN250-500 adopts out-of-band bypass valve structure. The purpose is to reduce the pressure difference between the front and back of the valve to avoid high flow rate, high scour and high temperature, thus ensuring the safe operation of the oxygen pipeline network, but also reducing the operating torque.


      2. Medium flow direction: PN (> 1.6MPa), DN (> 100) media flow from the bottom of the disc to the top of the disc (i.e. low in and high out), DN (> 125) media flow from the disc square to the bottom (high in and low out) o for the DN (> 125) valve using medium flow direction of high in and low out, on the one hand to meet the structural needs of the in-pass valve, on the other hand due to the medium pressure. The closing force of the valve is greatly reduced.


      Three, the valve is equipped with electrostatic safety device, which can avoid spark generated by static electricity.


      4. Compared with ordinary globe valves, the support part of the globe valves used in oxygen pipelines adopts a fully enclosed structure, and the protective cover plate on the support can be opened when the packing is pressed, thus playing the role of oil and dust prevention. And there is an obvious oil prohibition mark.


      Five. All parts are strictly degreased.
