built-in safety valve is a kind of safety protection device for railway and automobile LPG tanker or ground LPG storage tank, mainly used for overpressure protection. It can be automatically turned on when the system pressure exceeds the specified value, and a part of the gas in the system is discharged into the atmosphere, thus preventing the system from accidents due to excessive pressure
Definition and structure
The built-in safety valve is composed of a shell, a spring seat and a sealing ring, and has a completely closed structure design without external leakage point. Its structure is simple and compact, small size, low working pressure and stable and reliable, long service life, convenient and flexible installation, easy maintenance
Working principle
When the system pressure exceeds the specified value, the built-in safety valve will automatically open and quickly discharge a certain amount of media, so that the system pressure does not exceed the allowable value. When the pressure in the container is reduced to the allowable value, the valve will automatically close, so as to ensure that the system does not occur due to excessive pressure
To be used for overpressure protection. It can also be applied to steam and other medium equipment or pipelines at operating temperatures up to 425 ° C (Type C) and 500 ° C (Type I and type V) as an overpressure protection device
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 442 gallon liquid totes Special package is available on request.
