Description

Technical Field

[0001] The invention relates to the technical field of constant temperature and pressure stabilizing devices, and more specifically to a gas heating constant temperature and pressure stabilizing device for fuel gas processing. Background Art

[0002] The pressure regulating valve is one of the key components in the constant temperature and pressure stabilizing device for gas. It automatically adjusts the valve opening according to the pressure change of the gas to maintain the stability of the gas pressure. When the gas pressure increases, the pressure regulating valve automatically reduces the valve opening and reduces the gas flow, thereby reducing the pressure; conversely, when the gas pressure decreases, the pressure regulating valve increases the valve opening, increases the gas flow, and increases the pressure.

However, in the case of a small opening, the stability of the valve of the existing pressure-stabilizing device will deteriorate, and oscillation will easily occur. For a valve with a valve core, when the valve has a small opening, it may also cause a jump-open or jump-close phenomenon, affecting the stability of the air pressure inside the pressure tank. Moreover, the valve core and the valve body are worn for a long time, resulting in a poor sealing effect, which in turn leads to unstable pressure inside the pressure tank. Summary of the invention

When the valve with a valve core works at a small opening, it may also cause jumping open or jumping closed, affecting the stability of the air pressure inside the pressure tank. In addition, the long-term wear between the valve core and the valve body will cause the sealing effect to deteriorate, which in turn causes the pressure inside the pressure tank to be unstable.

During the installation of the tank cover 2, the buckle 32 corresponds to the position of the notch 30, and then the tank cover 2 is rotated so that the buckle 32 is engaged with the clamping seat 29. When the positions of the ear plate 1 31 and the ear plate 2 33 correspond, the ear plate 1 31 and the ear plate 2 33 are fixed by the existing screws, and then the material is added to the inside of the air pressure tank 1 through the first feed pipe 34 and the second feed pipe 35.
