Imported low temperature gate valve
Overview of imported cryogenic gate valve products
The American YLOK imported cryogenic gate valve is a kind of valve that depends on the pressure of the medium to be sealed. Its opening and closing part is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted and adjusted. Throttling. Cryogenic gate valves are suitable for cryogenic media such as methane, liquid natural gas, hexene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, and liquid hydrogen.
Main features of imported cryogenic gate valve
1. In order to prevent abnormal pressure rise in the middle cavity, a pressure relief hole is set on the inlet side of the ram
2. Determine the top length of the valve cover according to the working temperature of the valve to ensure reliable sealing of the valve stem packing
3. Reasonably select the materials of packing, gaskets and other parts according to the working temperature
4. Strictly control the chemical composition of the material and mechanical properties such as low temperature impact toughness
5. Adopt a variety of piping flange standards and sealing surface types, which are suitable for various engineering needs.
6. Light weight: The body is made of high-grade nodular black cast iron, which is about 20% to 30% lighter than the traditional gate valve, and is easy to install and maintain.
7. Flat-bottomed valve seat: Traditional gate valves often silt in the bottom groove of the valve due to foreign objects such as stones, wood, cement, iron filings, and other debris after the pipe is washed with water, which is easy to cause failure
Close tightly to form water leakage. The bottom of the elastic seat-sealed gate valve adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris siltation and makes the fluid flow unblocked.
8. Overall rubber encapsulation: The gate adopts high-quality rubber for overall inner and outer rubber. European first-class rubber vulcanization technology enables the vulcanized gate to ensure accurate geometric dimensions.
Moreover, the rubber and ductile cast gate are firmly connected, not easy to fall off, and have good elastic memory. water
9. Precision casting valve body: The valve body adopts precision casting, and the precise geometric dimensions make the inside of the valve body without any finishing to ensure the sealing of the valve.
Main application scope of imported cryogenic gate valve
Cryogenic gate valve is suitable for the medium temperature of -40℃～ -196℃～ -253℃. It is called cryogenic valve. It is mainly used for ethylene, liquefied natural gas installations, 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 cryogenic storage tanks and tank trucks, pressure swing adsorption oxygen generation equipment. The output liquid cryogenic medium, such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., is not only inflammable and explosive, but also vaporizes when the temperature rises, and the volume expands hundreds of times when it is vaporized.
