Gas Storage System: It mainly includes gas filling valve, manual globe valve, natural gas cylinder, gas cylinder mouth valve, high-pressure steel pipe, etc.
The natural gas density is very low under ambiance and atmospheric temperature, so as to store natural gas effectively, a compressing method is generally adopted to store natural gas to improve the storage content of it. The highest pressure for using CNG in vehicles is 20 MPa (It equals to compress 200 times of natural gas.)
There are safety valve and manual globe valve on gas cylinder (cylinder mouth valve) to ensure safe usage and convenient maintenance; There is safety valve on pressure regulator to ensure the security performance when there is any fault in the system.
