Description

Technical Field

[0001] This utility model belongs to the field of pressure valve technology, and in particular relates to a dynamic regulating pressure valve. Background Technology

[0002] In industrial fluid control systems, pressure stability is crucial for ensuring the safe and efficient operation of equipment. Therefore, pressure valves are used to regulate pressure. Currently, pressure valves include automatic and manual valves. Automatic pressure valves offer high adjustment accuracy, but their operating and maintenance costs are significantly higher than those of manual pressure valves. Manual pressure valves, as the core component for pressure regulation, are widely used in pneumatic, hydraulic, and water supply systems.

[0003] Traditional manual pressure valves often suffer from problems such as insufficient adjustment accuracy, cumbersome operation, and poor structural reliability in practical use, making it difficult to meet the needs of complex working conditions during pressure regulation. Therefore, a dynamic pressure regulating valve is needed to improve the problems of manual pressure valves. Utility Model Content

[0007] An upper diaphragm is mounted on the valve body. The upper diaphragm, the valve body, and the lower diaphragm form the upper chamber. When the upper diaphragm is pressed, it squeezes the lower diaphragm, so that the upper chamber communicates with the liquid inlet, allowing liquid to enter the upper chamber from the liquid inlet.

[0008] An elastic element is installed below and connected to the lower diaphragm to reset the lower diaphragm, thereby preventing the upper chamber from communicating with the inlet.

[0011] In a preferred embodiment of this invention, the moving block is connected to the upper diaphragm via a conductive spring, and the moving block approaches the upper diaphragm to press the upper diaphragm down.

[0012] In a preferred embodiment of this utility model, the outer nut is integrally formed with the mounting cover, and the upper diaphragm is located inside the mounting cover.

[0013] In a preferred embodiment of this utility model, an operation knob is provided at the end of the rotating shaft, and a limit nut is provided on the outer nut to limit the rotating shaft.

[0014] In a preferred embodiment of this utility model, the upper chamber and the liquid inlet are connected by a lower flow channel, the lower diaphragm is located in the lower flow channel, and the lower diaphragm is provided with a conical protrusion to open or close the lower flow channel.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] This embodiment provides a dynamic regulating pressure valve that enables precise manual adjustment. It has high adjustment accuracy and is easy to operate. Compared with automatic pressure valves, it can greatly reduce the cost of use and maintenance. Furthermore, the pressure valve of this utility model has a simple structure, good reliability, and is easy to maintain in actual use, and can meet the needs of pressure valves under complex working conditions.

[0026] Combination Figures 1 to 4As shown, the dynamic regulating pressure valve of this embodiment includes a valve body 10, an upper diaphragm 20, and an elastic element 30. An inlet 101 and an outlet 102 are connected to the valve body 10. An upper chamber 103 is provided inside the valve body 10, separated from the inlet 101 by a lower diaphragm 11. The upper chamber 103 communicates with the outlet 102. The upper diaphragm 20 is mounted on the valve body 10, forming the upper chamber 103 together with the valve body 10 and the lower diaphragm 11. When the upper diaphragm 20 is pressed, it squeezes the lower diaphragm 11, causing the upper chamber 103 to communicate with the inlet 101, allowing liquid to enter the upper chamber 103 from the inlet 101. The elastic element 30 is installed below and connected to the lower diaphragm 11 to reset the lower diaphragm 11, preventing communication between the upper chamber 103 and the inlet 101. In this embodiment, the upper chamber 103 is used to store liquid. During the operation of the pressure valve, the liquid enters the upper chamber 103 through the inlet 101 and then enters the outlet 102 to discharge the liquid. In this embodiment, the upper chamber 103 and the inlet 101 are connected by a lower flow channel 90. The lower diaphragm 11 is located in the lower flow channel 90 and is provided with a conical protrusion 111 to open or close the lower flow channel 90. In this embodiment, there is a gap between the upper chamber 103 and the lower flow channel 90. The size of the gap is adjusted by the lower diaphragm 11. When pressure reduction is required, the upper diaphragm 20 presses down on the lower diaphragm 11 to increase the gap and reduce the resistance of the liquid, thereby achieving a pressure reduction effect. In this way, the liquid pressure is dynamically adjusted, which is simple to operate and has higher adjustment accuracy.

[0027] In this embodiment, the dynamic regulating pressure valve also includes a base 100, which is installed below the valve body 10 and fixedly connected to the valve body 10. An elastic element 30 is disposed in the base 100. In this embodiment, the elastic element 30 is a return spring. The elastic element 30 is fixedly installed in the base 100 and the elastic element 30 resets the lower diaphragm 11 so as to separate the lower flow channel 90 from the upper chamber 103 through the lower diaphragm 11.

[0028] Combination Figure 1 and Figure 3As shown, the valve body 10 of this embodiment is provided with a pressing part 40, which is disposed above the upper diaphragm 20 to press down the lower diaphragm 11 through the upper diaphragm 20. The pressing part 40 includes an outer nut 41, a rotating shaft 42, and a moving block 43. The outer nut 41 is connected to the valve body 10 through a mounting cover 50. The rotating shaft 42 is installed inside the outer nut 41. The moving block 43 is threadedly engaged with the rotating shaft 42. When the rotating shaft 42 rotates, the moving block 43 moves along the length of the outer nut 41 within the outer nut 41. In this embodiment, the outer nut 41 and the mounting cover 50 are connected to the valve body 10. The cover 50 is integrally formed, and the upper diaphragm 20 is located inside the cover 50. The moving block 43 is attached to the inner wall of the outer nut 41. When the rotating shaft 42 rotates, the moving block 43 moves axially inside the outer nut 41. The moving block 43 and the upper diaphragm 20 are connected by a transmission spring 60. Therefore, while the moving block 43 is moving axially, it pushes the upper diaphragm 20 through the transmission spring 60, and the upper diaphragm 20 presses down on the lower diaphragm 11, thereby increasing the gap between the lower flow channel 90 and the upper chamber 103 and depressurizing the liquid.

[0029] In this embodiment, an operating knob 70 is provided at the end of the rotating shaft 42, and a limiting nut 80 is provided on the outer nut 41 to limit the rotation shaft 42. The operating knob 70 is connected to the rotating shaft 42, and the operator can rotate the rotating shaft 42 by operating the knob 70, making the operation more convenient. The limiting nut 80 can cooperate with the outer nut 41 to limit the operating knob 70 and prevent the operating knob 70 from being rotated too much.

[0030] In actual use, the pressure valve of this embodiment has a gap between the lower flow channel 90 and the upper chamber 103. The liquid pressure is changed by changing the size of the gap. When pressure reduction is required, the upper diaphragm 20 presses down on the lower diaphragm 11 to make the gap larger and the resistance of the liquid smaller, thus achieving the pressure reduction effect. The liquid pressure is dynamically adjusted in this way, which is simple to operate and has higher adjustment accuracy.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
