Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure stabilizing valves, and in particular to a pressure stabilizing valve capable of automatically adjusting pressure. BACKGROUND

[0002] A pressure stabilizing valve is a pressure control device capable of automatically adjusting the opening degree of a valve port through a mechanical feedback mechanism, and mainly comprises a valve body, a diaphragm assembly and a pressure regulating device. In the field of industrial fluid control, the pressure stabilizing valve is a core component for maintaining stable system pressure, and its performance directly affects the safety and efficiency of equipment operation. However, the traditional pressure stabilizing valve has technical bottlenecks such as complicated adjustment operation, slow response speed and weak anti-interference ability, and is difficult to meet the needs of modern industry for high pressure, high frequency and complex working conditions.

[0003] In the publication CN112178251A, a one-way flow regulating valve capable of automatically adjusting internal gas pressure is disclosed, which comprises a first pipeline, a second pipeline is installed above the first pipeline, a first magnet is installed inside the second pipeline, a hole is arranged in the first magnet, a second magnet is installed above the first magnet, a supporting rod is installed above the second magnet, a first recess is arranged inside the second pipeline, a first spring is installed inside the first recess, and a first baffle is installed outside the first spring. The one-way flow regulating valve capable of automatically adjusting internal gas pressure, the first magnet and the second magnet constitute a suction mechanism. When the internal gas pressure of the one-way flow regulating valve is too large, the second magnet is pushed upward to move, thereby driving the second baffle to move upward, so that the excess gas pressure of the one-way flow regulating valve is discharged from the inside of the second pipeline, thereby achieving the purpose of automatically adjusting the internal gas pressure of the one-way flow regulating valve.

[0004] The above-mentioned prior art, when in use, corresponds to the first pipeline. The existing pressure stabilizing valve, when in use, is fastened by bolts through the flanges on the valve body and the pipeline, and the sealing is realized by adding gaskets (such as metal wound gaskets and rubber gaskets) in the middle. The structure is bulky, there are many bolts, and they need to be matched one by one, which has the problem of complicated operation. Therefore, corresponding improvement is needed.

[0005] In the publication CN106931207A, a new type of fluid pressure stabilizing valve is disclosed, which comprises a valve body provided with an inlet, an outlet and a valve body cavity in communication with each other, a pressure stabilizing pipe is arranged in the valve body cavity, a pressure guiding hole is arranged at the first end of the pressure stabilizing pipe and communicated with the valve body cavity, and the tail end is communicated with the outlet; a pressure stabilizing device for adjusting the opening degree of the pressure guiding hole is arranged on the valve body. When the outlet pressure is higher or lower than the set pressure, the pressure stabilizing device dynamically adjusts with the change of the outlet pressure, so that the outlet pressure remains constant. The valve body cavity acts as a buffer cavity and plays a role in auxiliary adjustment and buffering when the pressure stabilizing device adjusts, further optimizing the adjustment effect and making the outlet pressure more constant.

[0006] The core components of the pressure stabilizing valve include a valve core, a valve seat, a spring and a sealing ring, and the matching gap is usually in the order of 0.01-0.1 mm. If the impurities in the fluid enter the gap, the valve core surface will be abraded like "sandpaper", causing the sealing surface to be scratched, the spring to be stuck or the sealing ring to be torn, thereby affecting the normal use of the pressure stabilizing valve. The prior art lacks filtering and intercepting of the particulate fluid, and therefore, corresponding improvement is needed. SUMMARY
