The first spring 3 and the second spring 4 are both connected with the diaphragm 5, the diaphragm 5 is used for sensing the change of fluid pressure, two ends of the diaphragm 5 are fixed on the inner wall of the cap 6, and the middle part of the diaphragm 5 can move up and down along with the first spring 3 and the second spring 4. The top of the connecting rod 7 is connected with the leather diaphragm 5, and the connecting rod 7 can move up and down along with the middle part of the leather diaphragm 5. The sealing baffle 8 is connected with the bottom of the connecting rod 7, and the sealing baffle 8 can move up and down along with the connecting rod 7. The inlet flange 13 and the outlet flange 14 are arranged at two ends of the main body 11, and the gas pressure regulator is connected with an external pipeline through the inlet flange 13 and the outlet flange 14. The first sealing side plate 9 is arranged at the bottom in the main body 11. The second sealing side plate 10 is arranged at the top in the main body 11. When the sealing baffle 8 is contacted with the first sealing side plate 9 and the second sealing side plate 10, the gas pressure regulator is in a closed state. When the sealing baffle 8 is not in contact with the first sealing side plate 9 and the second sealing side plate 10, the gas pressure regulator is in an opening state. The communication hole 12 is provided at the top of the main body 11. The space defined by the film 5, the body 11, and the cap 6 is a film lower space. The space formed by the main body 11, the outlet flange 14, the sealing baffle 8, the first sealing side plate 9 and the second sealing side plate 10 is a pressure regulator outlet space.

The specific operation process of the utility model is explained as follows:
the basic principle of a gas pressure regulator is a throttling effect, which causes a pressure reduction of a fluid, the degree of the pressure reduction of the fluid being related to the throttling effect, which is related to the degree of opening. The communicating hole 12 communicates the space under the skin with the outlet space of the pressure regulator, and the pressure of the space under the skin is consistent with that of the outlet space of the pressure regulator. The diaphragm 5 transmits fluid pressure to the first spring 3 and the second spring 4, the first spring 3 and the second spring 4 compress or stretch to drive the connecting rod 7 and the sealing baffle 8 to move up and down so as to control the distance between the sealing baffle 8 and the first sealing side plate 9 and the distance between the sealing baffle 8 and the second sealing side plate 10, the distance between the sealing baffle 8 and the first sealing side plate 9 and the distance between the sealing baffle 8 and the second sealing side plate 10 determine the opening degree of the gas pressure regulator, and the opening degree determines the size of fluid throttling effect, namely the pressure regulating range.
When the outlet pressure of the gas pressure regulator is reduced in a fluctuating way, the lower space of the membrane is communicated with the outlet space of the pressure regulator by the communicating hole 12, and the pressure of the lower space of the membrane is consistent with the pressure of the outlet space of the pressure regulator. The diaphragm 5 is pressed upward by fluid in the space below the diaphragm and is simultaneously pressed downward by the elastic force of the first spring 3 and the second spring 4. When outlet pressure descends, the pressure of the fluid acting upwards in the space below the diaphragm 5 is reduced, the first spring 3 and the second spring 4 push the diaphragm 5 to move downwards, the connecting rod 7 and the sealing baffle 8 move downwards along with the diaphragm 5, the distance between the sealing baffle 8 and the first sealing side plate 9 and the distance between the sealing baffle 8 and the second sealing side plate 10 are increased, namely the opening degree of the gas pressure regulator is increased, and the opening degree is increased to promote the outlet pressure of the gas pressure regulator to be increased. Therefore, when the outlet pressure of the gas pressure regulator is reduced, the gas pressure regulator can be automatically adjusted to be raised to a set state.
When the outlet pressure of the gas pressure regulator rises in a fluctuating way, the lower space of the membrane is communicated with the outlet space of the pressure regulator by the communicating hole 12, and the pressure of the lower space of the membrane is consistent with the pressure of the outlet space of the pressure regulator. The diaphragm 5 is pressed upward by fluid in the space below the diaphragm and is simultaneously pressed downward by the elastic force of the first spring 3 and the second spring 4. When outlet pressure rose, the involucra 5 received the ascending pressure rise of effect of the interior fluid of involucra lower part space, and spring one 3, spring two 4 pulling involucra 5 upwards move, and connecting rod 7, seal baffle 8 follow involucra 5 upwards moves, and the distance between seal baffle 8 and sealed curb plate one 9, two 10 of sealed curb plate diminishes, and the opening degree of gas pressure regulator diminishes promptly, and the opening degree diminishes and impels gas pressure regulator outlet pressure to reduce. Therefore, when the outlet pressure of the gas pressure regulator is increased, the gas pressure regulator can be automatically adjusted to be reduced to a set state.
To sum up, the device sets up spring one, spring two, involucra and spring baffle and realizes the response and the regulation of outlet pressure, and the difficult condition that fatigue failure appears of two springs, and life is longer, and has stronger stability at compression and tensile in-process.
