Abstract
A pressure regulator has a valve tube assembly, a gas-input assembly, a first regulating assembly and a second regulating assembly. The gas storage device has a storage unit and the pressure regulator. By the first and the second regulating assemblies, the effect of adjusting down the gas pressure is achieved to maintain the safety of use. The pressure regulator is partially embedded in the gas storage unit to reduce the overall volume of the gas storage device. However, the high-pressure piston chamber of the valve tube assembly communicates with the outside of the gas storage unit through the high-pressure gas channel to maintain the normal operation of the elastic element in the high-pressure piston chamber.
Claims11
A pressure regulator, comprising:
- a valve tube assembly having
- a first internal tube having a chamber;
- an external tube having an end mounted inside the first internal tube;
- a second internal tube mounted in the first internal tube and having
- an elongated groove formed on an outside wall of the second internal tube;
- and
- a high-pressure exhaustion hole formed transversely through the second internal tube;
- a gas inlet orifice disposed transversely in the external tube;
- a gas outlet orifice disposed transversely in the external tube;
- a high-pressure piston chamber formed axially through the second internal tube and communicating with the chamber of the first internal tube through the high-pressure exhaustion hole of the second internal tube;
- an intermediate chamber disposed axially in the external tube;
- a low-pressure chamber disposed axially in the external tube, selectively communicating with the gas outlet orifice, and selectively communicating with the intermediate chamber;
- a low-pressure piston chamber;
- and
- a high-pressure exhaustion channel disposed in the external tube and having
- an axial part formed axially through the external tube and communicating with the high-pressure piston chamber;
- and
- a radial part formed transversely through the external tube and communicating with the axial part and adapted for communicating with an outside of the valve tube assembly;
- a gas-input assembly disposed in the gas inlet orifice of the valve tube assembly;
- a first regulating assembly disposed in the high-pressure piston chamber and the intermediate chamber of the valve tube assembly and adapted to reduce a gas pressure of a gas flowing through the first regulating assembly;
- and
- a second regulating assembly disposed in the low-pressure piston chamber and the low-pressure chamber of the valve tube assembly and adapted to reduce a gas pressure of a gas flowing from the intermediate chamber into the second regulating assembly.
