LNG safety valve structural features Imported regulating valve, imported electromagnetic valve, imported steam trap, imported pressure reducing valve, imported diaphragm pump, multi-stage pump LNG safety valve refers to the low temperature LNG LNG system, open and close parts by external force Under the effect of being normally closed, when the pressure of low-temperature LNG LNG medium in the cryogenic equipment or pipeline rises above the specified value, LNG LNG is discharged outside the system to prevent the valve in the cryogenic pipeline or equipment from exceeding the specified value. The control of low temperature LNG liquefied natural gas does not exceed the specified value, and plays an important role in personal safety and equipment operation. The structural features of LNG safety valves are:
1. The cryogenic safety valve is cryogenic and cryogenic, and can withstand -196°C cryogenic temperature. 2. The cryogenic safety valve disc material is chrome plated or nitrided to increase the surface hardness of the stem and improve the reliability of the packed seal.
3. The gasket used for cryogenic safety valve has reliable sealing and recovery under normal temperature, low temperature and temperature change.
4. The low-temperature safety valve adopts high-quality American Weidun spring material, which ensures accurate and safe take-off emissions.
5, start freely, reliable sealing, stable starting pressure, etc. 6. Opening height ≥ 1/4 throat diameter, large emission;
7. A safety valve with a wrench can be opened manually using a wrench when the medium pressure reaches more than 75% of the opening pressure;
8, there are threads, flanges, welding, a variety of connections, with welded pipe removable installation and maintenance.

PE Brine Tank are used in water treatment projects, water softening complete sets of equipment, and accessories on water treatment complete sets of equipment. The colors are various. PE salt tanks are acid and alkali resistant, not easy to age, non-toxic and tasteless, and have a long service life. The main function of the salt box is to soak the softening salt, so that the softening salt can be fully dissolved, and the resin can be regenerated better.
