Technical Field
[0001] The utility model relates to the technical field of overflow valves, in particular to an overflow valve. Background Art
[0002] The overflow valve is a hydraulic pressure control valve that mainly plays the role of constant pressure overflow, pressure stabilization, system unloading and safety protection in hydraulic equipment. The overflow valve has many fault manifestations during use, and the majority of faults are noise and vibration. The main reason is that it is caused by uneven pressure.
[0003] For example, a relief valve with the announcement number CN220667983U belongs to the technical field of hydraulic systems. The relief valve includes a relief valve body, an oil inlet is provided on the relief valve body, and the oil inlet includes a sealing ring, an oil inlet pipe and a connecting flange. A vacuum sleeve is provided on the outside of a section of the oil inlet pipe, and a vacuum outlet is provided on the vacuum sleeve. The oil inlet pipe located on the inside of the vacuum sleeve uses a microporous air permeable pipe. The gas in the hydraulic oil is effectively sucked out through the structure of the oil inlet pipe, thereby reducing the gas content in the hydraulic oil, so that when the relief valve is used, the gas content in the hydraulic oil is low, the hydraulic oil pressure is more stable, and the failure rate is lower.
[0004] The above patent proposes that when the overflow valve is in use, the gas content in the hydraulic oil is low, the hydraulic oil pressure is more stable, and the failure rate is lower. However, the pipelines of the above device are connected through connecting flanges. When the pipeline is disassembled, special tools are required to remove the nuts on the flange before it can be taken out, which is troublesome, time-consuming and labor-intensive.
[0005] Therefore, we propose a relief valve to solve the above problems. Utility Model Content
[0006] The utility model aims to provide a relief valve to solve the problem that the pipelines of the above-mentioned device proposed in the background technology are connected to each other through connecting flanges. When the pipelines are disassembled, special tools are needed to remove the nuts on the flanges before they can be taken out, which is troublesome, time-consuming and labor-intensive.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an overflow valve, comprising an overflow valve housing and a water supply pipe connected and arranged on both sides of the overflow valve housing, the two ends of the two water supply pipes are respectively connected and fixedly installed with a connecting cylinder, one end of the connecting cylinder is interspersed with a connecting pipe, one end of the connecting pipe is fixedly installed with a limiting disc, and the connecting cylinder is provided with a connecting component for limiting the connecting pipe.
[0008] Preferably, the connecting component includes a circular ring fixedly installed on the inner cavity side wall of the connecting cylinder and an installation groove formed on the circular ring. An airbag is fixedly installed in the installation groove. Notches are formed on the side walls of both the airbag and the circular ring. The airbag is located on one side of the limit disc.
[0009] Preferably, a limiting panel is fixedly installed at the lower end of the airbag. The limiting panel is arranged on one side of the limit disc.
[0010] Preferably, springs are fixedly connected to the inner cavity side wall and the bottom wall of the airbag.
[0011] Preferably, a positioning panel is fixedly installed on the axial side wall of the connecting pipe. There is a gap between the positioning panel and the limit disc. The airbag and the limiting panel are inserted into the gap between the positioning panel and the limit disc.
[0012] Preferably, an annular ring is fixedly installed on the side wall of the circular ring. The diameter of the annular ring gradually increases from inside to outside.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. With the cooperation of the connecting pipe, the connecting cylinder, the water delivery pipe, the annular ring, the notch and the airbag, a large amount of water will be filled into the airbag, and it will expand rapidly. The airbag will drive the limiting panel at the lower end to gradually move closer to the connecting pipe until it contacts the pipe side wall of the connecting pipe. When water is filled in, the airbag will squeeze the limiting panel to cause its own expansion, filling the gap between the limit disc and the positioning panel. When the airbag is saturated, water will no longer enter the airbag through the notch. At this time, the connecting pipe is limited, and the connection between the connecting pipe and the connecting cylinder can be conveniently realized. Without using any tools, the docking of the pipes can be completed. The operation is simple and the use is convenient.
[0015] 2. The airbag and the limiting panel are inserted into the gap between the positioning panel and the limit disc, which can make the expanded airbag better block the gap between the connecting pipe and the connecting cylinder, realizing the sealing between the connecting pipe and the connecting cylinder.
[0016] 3. The diameter of the annular ring gradually increases from inside to outside. Through the setting of the annular ring size, the diversion of water can be realized, and at the same time, the position where the connecting pipe moves can be limited, ensuring that the airbag and the limiting panel can be inserted into the gap between the positioning panel and the limit disc, realizing the limitation of the connecting pipe.

[0024] Embodiment
[0025] Please refer to Figures 1 - 5 , an overflow valve, which includes an overflow valve housing 1 and water delivery pipes 4 communicatively arranged on both sides of the overflow valve housing 1. Connecting cylinders 3 are fixedly installed at both ends of the two water delivery pipes 4. One end of the connecting cylinder 3 is penetrated with a connecting pipe 2, and a limit disc 6 is fixedly installed at one end of the connecting pipe 2. A connecting component 8 for limiting and connecting the connecting pipe 2 is arranged on the connecting cylinder 3.
[0026] The connecting component 8 includes a ring 81 fixedly installed on the inner cavity side wall of the connecting cylinder 3 and an installation groove 86 opened on the ring 81. An airbag 82 is fixedly installed in the installation groove 86. Notches 83 are opened on the side walls of the airbag 82 and the ring 81. The airbag 82 is located on one side of the limit disc 6. Through the setting of the notch 83, water can quickly enter the airbag 82, so that it can expand quickly, ensuring that there is no gap between the connecting pipe 2 and the connecting cylinder 3, and realizing sealing.
[0027] A limiting panel 85 is fixedly installed at the lower end of the airbag 82. The limiting panel 85 is arranged on one side of the limit disc 6, which can make the airbag 82 better in limiting contact with the connecting pipe 2.
[0028] On the inner cavity side wall and the bottom wall of the airbag 82, springs 84 are fixedly connected. Through the arrangement of the springs 84, it can be ensured that when the airbag 82 is not filled with water and stops working, the airbag 82 can quickly return to its initial position.
[0029] A positioning panel 7 is fixedly installed on the axial side wall of the connecting pipe 2. There is a gap between the positioning panel 7 and the limiting disc 6. The airbag 82 and the limiting panel 85 are inserted into the gap between the positioning panel 7 and the limiting disc 6, which can make the inflated airbag 82 better block the gap between the connecting pipe 2 and the connecting cylinder 3.
[0030] An annular ring 5 is fixedly installed on the side wall of the circular ring 81. The caliber of the annular ring 5 gradually increases from inside to outside. Through the setting of the size of the annular ring 5, the diversion of water can be realized, and at the same time, the moving position of the connecting pipe 2 can be limited, ensuring that the airbag 82 and the limiting panel 85 can be inserted into the gap between the positioning panel 7 and the limiting disc 6 to realize the limitation of the connecting pipe 2.
[0031] In this embodiment, first, one end of the connecting pipe 2 is inserted into the inner cavity of the connecting cylinder 3. When the overflow valve housing 1 conducts water through the water delivery pipe 4, the water in the water delivery pipe 4 enters the connecting cylinder 3. Through the setting of the annular ring 5, the water will be diverted by the annular ring 5, and a large amount of water preferentially passes through the diversion of the annular ring 5 through the notch 83 into the airbag 82. At this time, a large amount of water will be filled into the airbag 82, and it will quickly expand. The airbag 82 will drive the lower limiting panel 85 to gradually move closer to the connecting pipe 2 until it contacts the pipe side wall of the connecting pipe 2. When water is filled, the airbag 82 will squeeze the limiting panel 85 to cause itself to expand and fill the gap between the limiting disc 6 and the positioning panel 7. When the airbag 82 is saturated, water will no longer enter the airbag 82 through the notch 83. At this time, the connecting pipe 2 is limited, and the connection between the connecting pipe 2 and the connecting cylinder 3 can be conveniently realized. Without using any tools, the docking of the pipes can be completed, and the operation is simple and the use is convenient.
