Description

Technical Field

[0001] The utility model relates to the technical field related to accumulators, in particular to an accumulator with a pressure regulating mechanism. Background Art

[0002] The accumulator is an energy storage device in the hydraulic and pneumatic system. It converts the energy in the system into compression energy or potential energy and stores it at the right time. When the system needs it, it converts the compression energy or potential energy into hydraulic or air pressure energy and releases it to replenish the system. When the system pressure increases instantly, it can absorb this part of the energy to ensure the normal pressure of the entire system.

[0003] In the prior art, in the patent application entitled "A Diaphragm Accumulator Air Pressure Regulating Device" with the authorization publication number CN219242323U and the authorization publication date 2023-06-23, the regulating pump is a gas pump, and the regulating pump regulates the volume of the cavity by filling nitrogen into the cavity, and the regulating pump is connected to the container through a thread, and the regulating pump and the container are detachable through the thread. When not in a harsh environment, it is not necessary to regulate the pressure of the gas part of the diaphragm accumulator. At this time, the regulating pump and the base can be removed, and the pipeline can be sealed at the same time, thereby reducing the volume of the utility model and facilitating the use of the diaphragm accumulator;

[0004] In the above device, pressure regulation is achieved by pumping nitrogen through a regulating pump, and the regulating pump is connected to the container through a thread, which causes the pipeline connected to the regulating pump to rotate multiple times, affecting the connection effect between the pipeline and the regulating pump. At the same time, the air pump, as a mechanical device, may malfunction or be damaged, resulting in failure of the air pressure regulation function, and the air pump regulation system may be relatively complex and have high requirements on environmental conditions.

[0005] Therefore, we propose an accumulator with a pressure regulating mechanism to solve the above problems. Utility Model Content

[0006] 1. Technical problems to be solved by the utility model:

[0007] The purpose of the utility model is to provide an accumulator with a pressure regulating mechanism to solve the problems in the current market raised by the above background technology.

[0008] 2. Technical solution:

[0009] To achieve the above object, the utility model provides the following technical solution: an accumulator with a pressure regulating mechanism, comprising an accumulator body, a mounting frame is installed on the outer side of the middle part of the accumulator body, and an injection pipe is installed on the front end of the mounting frame, the rear end of the injection pipe is communicated with the interior of the accumulator body, and a sealing cap is arranged on the front end of the injection pipe, and a connecting pipe is threadedly connected to the outer side of the front end of the injection pipe, and the injection pipe is connected to the sealing cap through the connecting pipe;

[0010] An adjusting cylinder is connected to the upper middle end of the injection tube, and a piston rod is slidably installed inside the adjusting cylinder. The upper end of the piston rod is located outside the upper end of the adjusting cylinder. The internal air pressure of the adjusting cylinder is adjusted by moving the piston rod up and down, and a positioning mechanism is installed between the piston rod and the adjusting cylinder, and the positioning mechanism is used to fix the piston rod.

[0011] Furthermore, the front end of the injection pipe is fixedly connected with an insertion pipe, and a sealing gasket is sleeved on the outer side of the insertion pipe, and the connecting pipe and the sealing cover are threadedly connected.

[0012] Through the above technical solution, the connection sealing can be improved by using the sealing gasket.

[0013] Furthermore, the positioning mechanism includes a fixed seat fixedly installed on the upper end of the adjusting cylinder, and a guide rod is fixed to the front end of the fixed seat, and a driving frame is sleeved on the outer side of the guide rod, and a pressure spring is sleeved on the outer side of the guide rod, and both ends of the pressure spring are respectively connected to the fixed seat and the driving frame.

[0014] Through the above technical solution, the drive frame can be pressed against the piston rod by the pressure spring.

[0015] Furthermore, the driving frame is a "mouth"-shaped structure, and the driving frame fits the middle part of the piston rod, and a positioning block is fixed to the inner wall of the driving frame, and the positioning block is rectangular.

[0016] Through the above technical solution, the driving frame can drive the positioning block to extend into the interior of the piston rod.

[0017] Furthermore, positioning grooves which match the positioning block in a concave-convex manner are formed at equal intervals on the rear side of the piston rod.

[0018] Through the above technical solution, fixation is achieved through the cooperation of the positioning block and the positioning groove.

[0019] 3. Beneficial effects:

[0020] By adopting the technical solution provided by the utility model, compared with the prior art, the utility model has an accumulator with a pressure regulating mechanism, and the injection pipe can be connected to the air pump and the sealing cover respectively according to needs, so as to realize two modes of air pump regulation and manual regulation. The specific contents are as follows:

[0021] When the accumulator body uses the air pump to adjust the pressure, first rotate the connecting pipe to drive the connecting pipe out of the sealing cover, then insert the air pump ventilation pipe into the outside of the insertion pipe, and then rotate the connecting pipe in the opposite direction to connect the connecting pipe with the end of the air pump ventilation pipe, so as to realize the quick connection between the accumulator body and the air pump, and realize the pressure adjustment operation through the air pump. At the same time, when connecting the connecting pipe and the air pump ventilation pipe, there is no need to rotate the air pump ventilation pipe to ensure the connection stability between the air pump and the ventilation pipe;

[0022] When it is inconvenient to use an air pump on the accumulator body, install the sealing cover to the front end of the injection pipe, and then press the drive frame, which drives the positioning block to disengage from the positioning groove. Then, slide the piston rod up and down inside the adjusting cylinder to achieve pressure changes inside the injection pipe. Then release the drive frame, which drives the positioning block to extend into the corresponding positioning groove to fix the moved piston rod. Compared with the air pump adjustment system, it does not require additional air pump equipment and related piping systems, and is simpler to operate and more reliable.
