Liquefied natural gas safety valve is used for low temperature LNG liquefied natural gas system, the opening and closing parts are normally closed under the external force, when the cryogenic equipment or pipeline LNG LNG medium pressure exceeds the specified value, by the system Outside LNG liquefied natural gas to prevent low-temperature pipeline or equipment within the media pressure exceeds the specified value of the valve. LNG liquefied natural gas control does not exceed the specified value, the personal safety and equipment plays an important protective role, liquefied natural gas safety valve Structural features: 1, cryogenic safety valve after cryogenic treatment, resistant to -196 ℃ low temperature 2, low temperature valve material after chrome plating or nitriding, improve stem surface hardness and improve the reliability of packing seal. 3, low temperature safety valve gasket with a room temperature, low temperature conditions and temperature changes can be reliable sealing and recovery. 4, low-temperature safety valve using high-quality US-based shield spring material, take-off discharge accurate and safe. 5, Start-up, reliable sealing, take-off pressure and stability 6, open the height of ≥ 1/4 throat diameter, large emissions; 7, with a wrench safety valve, when the media pressure reaches more than 75% of the opening pressure, you can use the wrench to open manually; 8, a thread, flange, welding, a variety of connections, with welded pipe detachable installation and maintenance easy. ã€Print】 ã€Close】
