Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure relief device technology, and in particular to a compressor pressure relief structure. Background Technology
[0002] During compressor operation, if excessive system pressure is not relieved in time, it can cause serious damage to the compressor and the entire system, such as damage to sealing components and pipe rupture, affecting the normal operation and service life of the equipment. Traditional compressor pressure relief devices are often complex in structure, slow in response, and prone to generating large impacts during the pressure relief process, further affecting the stability of the equipment. Therefore, a compressor pressure relief structure is provided here. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a compressor pressure relief structure. During pressure relief, the gas pushes the conical sealing plug upward, allowing the gas to enter the valve body and then exit through the guide pipe inside the exhaust pipe. After further buffering by the buffer sponge, the high-pressure gas exits through the exhaust hole of the end cover. This solves the problems of complex and large impact of traditional pressure relief structures, improves the safety and reliability of the compressor, and features a compact and practical structure that overcomes the shortcomings of existing technologies.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A compressor pressure relief structure includes a valve body with open upper and lower ends. The lower end of the valve body is configured as an air inlet. The inner wall of the upper end of the valve body has a connection port, and a top cover is screwed onto the connection port. An exhaust pipe is provided on the side wall of the valve body. A conical hole is provided on the inner wall of the air inlet. A conical sealing plug is provided at the conical hole. An elastic reset component is provided between the conical sealing plug and the top cover. An exhaust buffer structure is provided on the inner wall of the exhaust pipe. A rectangular block is provided at the top of the top cover.
[0006] As a further embodiment of this utility model: the elastic reset assembly includes a support column fixed to the conical sealing plug, the upper end of the support column being slidably inserted into the bottom of the top cover, and a spring being sleeved on the part of the support column located between the top cover and the conical sealing plug.
[0007] As a further improvement of this utility model: the exhaust buffer structure includes a partition fixed in the middle of the inner wall of the exhaust pipe, and guide pipes are fixed at equal intervals on the partition.
[0008] As a further improvement of this utility model: an end cap is screwed to the end of the exhaust pipe away from the valve body, an exhaust hole is provided on the end cap, and a cushioning sponge is filled on the inner side of the end cap and at the end of the exhaust pipe.
[0009] As a further improvement of this invention, the diameter of the buffer sponge is larger than the diameter of the vent hole.
[0010] As a further improvement of this utility model, the outer diameter of the conical sealing plug is smaller than the inner diameter of the valve body.
[0011] The beneficial effects of this utility model are as follows:
[0012] When the pressure is released, the gas pushes the conical sealing plug upwards, and the gas enters the valve body. It then exits along the guide pipe inside the exhaust pipe. After being further buffered by the buffer sponge, the high-pressure gas is discharged from the exhaust hole of the end cover. This solves the problems of complex and large impact of traditional pressure relief structures, improves the safety and reliability of the compressor, and has a compact and practical structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example 1, referring to Figure 1-4A compressor pressure relief structure includes a valve body 1, which is open at both the top and bottom. The lower end of the valve body 1 is configured as an air inlet 2. The upper inner wall of the valve body 1 is provided with a connection port 9, and a top cover 6 is screwed to the connection port 9. An exhaust pipe 3 is provided on the side wall of the valve body 1. A conical hole 8 is provided on the inner wall of the air inlet 2. A conical sealing plug 12 is provided at the conical hole 8. An elastic reset component is provided between the conical sealing plug 12 and the top cover 6. An exhaust buffer structure is provided on the inner wall of the exhaust pipe 3. A rectangular block 10 is provided at the top of the top cover 6.
[0020] The elastic reset assembly includes a support column 14 fixed to the conical sealing plug 12. The upper end of the support column 14 is slidably inserted into the bottom of the top cover 6. A spring 13 is fitted on the part of the support column 14 located between the top cover 6 and the conical sealing plug 12.
[0021] The exhaust buffer structure includes a baffle 11 fixed in the middle of the inner wall of the exhaust pipe 3, and guide pipes 7 are fixed at equal intervals on the baffle 11.
[0022] An end cap 4 is screwed to the end of the exhaust pipe 3 away from the valve body 1. An exhaust hole 5 is provided on the end cap 4. The inner side of the end cap 4 and the end of the exhaust pipe 3 is filled with a cushioning sponge 15.
[0023] The diameter of the cushioning sponge 15 is larger than the diameter of the vent hole 5 to prevent the cushioning sponge 15 from leaking out of the vent hole 5.
[0024] The outer diameter of the conical sealing plug 12 is smaller than the inner diameter of the valve body 1, ensuring that gas can enter the interior of the valve body 1.
[0025] Working principle: Connector 9 is screwed to the compressor's pressure relief port. Conical sealing plug 12 normally blocks the conical hole 8 of the air inlet. When the compressor pressure is too high, the gas pushes the conical sealing plug 12 upward, and the gas enters the valve body 1. Then it is discharged along the guide pipe 7 inside the exhaust pipe 3. After being further buffered by the buffer sponge 15, the high-pressure gas is discharged from the exhaust hole 5 of the end cover 4. This solves the problems of complex and large impact of traditional pressure relief structures, improves the safety and reliability of the compressor, and has a compact and practical structure.
[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
