Produced by Shanghai Guanhuan Valve Manufacturing Co., LtdLow temperature long axis needle valve, DJ11W-40P low-temperature long axis needle valveMainly used in ethylene, liquefied natural gas plants, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low-temperature storage tanks and tank trucks, pressure swing adsorption oxygen production and other devices. The output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc. are not only flammable and explosive, but also require gasification when heated, and the volume expands hundreds of times during gasification.
Product Structure Features:
1. The low-temperature valve gasket adopts a stainless steel leather jacket polytetrafluoroethylene or flexible graphite winding gasket structure;
2. The sealing surface of low-temperature valves is welded with cobalt based hard alloy, which has small deformation and wear resistance at low temperatures, and can maintain good sealing performance.
3. The valve cover of the low-temperature valve is designed with a long neck structure, which can isolate the influence of low-temperature medium on the packing and make the valve open and close flexibly;
4. The packing adopts a combination structure of flexible graphite or polytetrafluoroethylene, and the crown ring low-temperature valve has good low-temperature resistance performance;
