Embodiment 1

[0036] Embodiment 1, a pressure reducing valve adjustment assembly, such as image 3 As shown, the same as the prior art, the pressure reducing valve includes a valve body 8, the right end of the valve body 8 is an inlet cavity 86, and the left end is an outlet cavity 87, the inlet cavity 86 is connected with an inlet port, and the outlet cavity 87 is connected with an outlet end. The lower port of the valve body 8 is sealingly connected with a valve body blocking cover 81, and the upper port is sealingly connected with a spring cover 11. A diaphragm 3 is arranged between the spring cover 11 and the upper port of the valve body 8, and the adjustment assembly is arranged on the valve body. Between the blocking cover 81 and the spring cover 11. An adjustment rod 12 is arranged on the spring cover 11 and an adjustment spring 1 is arranged inside.

[0037] Specifically, such as image 3 with figure 1 As shown, the adjustment assembly includes an adjustment rod 12 arranged on t...

Embodiment 2

[0042] Embodiment 2, a pressure reducing valve adjustment assembly, the end of the ejector rod 5 passing through the throttle port 82 is provided with a valve assembly 6 that is movable and sealed with the valve body cover 81, and the valve assembly 6 includes a valve assembly that is sequentially sleeved on the ejector rod 5. The second seal 60 at the end, the valve connecting body 62, and the return spring 7 are arranged between the valve connecting body 62 and the valve body blocking cover 81. The valve connecting body 62 blocks the second seal 60 at the end of the ejector rod 5. When the ejector rod 5 moves downward, the second seal 60 is far away from the throttle port 82, and the throttle port 82 is opened or enlarged. , when the ejector rod 5 moves up under the action of the return spring 7, the second sealing member 60 presses against the throttle port 82, and the throttle port 82 is closed or becomes smaller.

[0043] Specifically, the valve connecting body 62 is conn...

Embodiment 3

[0045] Embodiment 3, a pressure reducing valve adjustment assembly, such as figure 2 with Figure 4 As shown, the valve connecting body 62 includes an upper end portion 64 and a lower end portion 65. The diameter of the upper end portion 64 is larger than the diameter of the lower end portion 65, which not only ensures the reliability of supporting the second sealing member 60, but also reduces the weight of the valve assembly. The weight and volume reduce the occupied internal cavity space, making the reciprocating movement of the valve assembly more flexible.

[0046] The upper end portion 64 is provided with a coaxial central light hole 66 and a second seal installation groove 67, the second seal member 60 is installed in the second seal installation groove 67, and the smooth end of the push rod 5 passes through the second seal installation groove 67. The sealing member 60 is tightly fitted with the central optical hole 66, and the second sealing member 60 preferably uses...

Abstract

The invention discloses a pressure reducing valve adjusting assembly which solves the technical problems that an existing pressure reducing valve adjusting assembly cannot meet the requirements for large pressure adjusting range, small outlet flow and stable outlet pressure in the fields of battery pack machining and the like. The device comprises a lower spring seat located between an adjusting spring and a diaphragm, an ejector rod seat is arranged below the diaphragm in an ejecting and pressing mode, a spring seat center through hole is formed in the lower spring seat, a diaphragm center through hole is formed in the diaphragm, and the ejector rod seat comprises a large-diameter section ejecting and pressing the diaphragm and a small-diameter section penetrating through the diaphragm center through hole and the spring seat center through hole. A first sealing piece surrounding the periphery of the central through hole of the diaphragm is arranged between the upper end face of the large-diameter section and the lower end face of the diaphragm in a sealed mode, a locking nut is arranged at the end, penetrating out of the central through hole of the spring seat, of the small-diameter section, and the lower end face of the locking nut is pressed on the end face of the lower spring seat. The pressure reducing valve can meet the requirements of high adjusting precision and small outlet pressure tolerance range in vibration, impact, high-temperature and low-temperature environments and the like.

Description

technical field [0001] The invention relates to the technical field of a pressure relief valve adjustment mechanism, in particular to a pressure relief valve adjustment assembly. Background technique [0002] The pressure reducing valve can decompress high-pressure nitrogen into stable low-pressure nitrogen, and then deliver the nitrogen to the battery pack to isolate the battery from direct contact with oxygen and prevent the battery from spontaneous combustion, explosion and other hazards. With the continuous and rapid development of new energy, new energy is gradually applied to passenger cars, and the safety performance of new energy passenger cars has received more and more attention from the state. Therefore, the performance requirements for pressure reducing valves have been further improved, and there are strict requirements on their outlet pressure and flow. Standards are required. [0003] The existing Chinese utility model patent application with authorization an...
