Description

Technical Field

[0001] The utility model relates to the technical field of air regulating safety valves, in particular to an air regulating safety valve which can automatically regulate air flow pressure. Background Art

[0002] An air valve is a special valve used to prevent negative pressure from being generated in a pipe due to a decompression wave during a transient process. It is usually installed at a high point where the dynamic water pressure is low during normal operation of the pipeline and where liquid column separation may occur during transient flow. Air is inhaled when the pressure in the pipeline is lower than atmospheric pressure, and air is discharged when the pressure in the pipeline rises above atmospheric pressure. During the exhaust process, the valve can automatically close when the liquid in the pipeline fills the pipeline, and liquid is not allowed to leak into the atmosphere.

A sealing ring is arranged on the outer surface of the sealing block 609, and the sealing block 609 is arranged in a truncated cone shape.

[0028] Analysis of the above content: The valve body 1 is installed to the desired position through the mutual cooperation of the connecting hole 3 and the flange 2, and the movable plate 606 is driven downward by the limit spring 612, so that the sealing block 609 extends into the sealing hole 605, and the valve body 1 is in a sealed state. The magnetic force generated by the electromagnet 9 is changed by changing the current flowing through the electromagnet 9, and the iron block 608 is attracted by the magnetic force to overcome the elastic force of the limit spring 612 and move upward, thereby driving the sealing block 609 to move out of the sealing hole 605, so that the gas flows out from the sealing hole 605, and the pressure of the gas is adjusted. The air flow pressure of the air is adjusted by changing the opening size of the sealing hole 605.

[0029] Embodiment 2:
