Description

Technical Field

[0001] This utility model relates to the field of gas booster pump technology, and in particular to a gas booster pump inlet connector with a filter assembly. Background Technology

[0002] A gas booster pump is a key component in a gas delivery system, primarily used to increase gas pressure, ensuring stable gas delivery in pipelines or meeting the pressure requirements of specific equipment. The gas booster pump inlet connector is a device connected to the gas booster pump's inlet end, through which gas is delivered to the booster pump for pressurization.

[0003] The existing gas booster pump intake connector has the following shortcomings when used: the gas booster pump intake connector can only serve a connection function. It has a filter component installed inside, which is not convenient for filtering solid particles and droplets in the gas. This causes solid particles and droplets to enter the gas booster pump, which can easily damage the gas booster pump and affect the purity of the gas. Therefore, the gas booster pump intake connector is not effective.

[0004] Therefore, those skilled in the art have proposed a gas booster pump inlet connector with a filter assembly to solve the aforementioned problems. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a gas booster pump inlet connector with a filter assembly, which can achieve the effect of filtering solid particles and liquid droplets in gas, including:

[0032] The main body 100 includes a gas booster pump body 101 and an air inlet connector body 102 and an air outlet connector 105 disposed on the gas booster pump body 101. A sealing cap 103 is threadedly connected to the air inlet connector body 102, and an air inlet connector 104 is installed on the air inlet connector body 102.

[0033] It should be noted that the main body 101 of the gas booster pump is an existing device, and the specific model and working principle will not be described here. The inlet connector 104 is connected to the gas delivery pipe, and the outlet connector 105 outputs the boosted gas.

[0034] The anti-loosening component 200 includes a fixing seat 201 provided on the sealing cover 103, a positioning rod 205 provided in the fixing seat 201, and a positioning hole 206 connected to the positioning rod 205 on the air inlet connector body 102, which is used to prevent the sealing cover 103 from loosening.

[0035] The filter assembly 400 includes a mounting frame 401 disposed on the inner wall of the air intake connector body 102, a metal filter screen 402 disposed in the mounting frame 401, and a glass fiber layer 403 disposed on the inner wall of the air intake connector body 102.

[0036] During use, the metal filter 402 on the filter assembly 400 can intercept solid particles in the gas, and the glass fiber layer 403 can adsorb fine particles and droplets in the gas, ensuring the purity of the gas and improving the performance of the gas booster pump intake connector. The threaded connection between the sealing cover 103 and the intake connector body 102 facilitates the replacement of the metal filter 402 and the glass fiber layer 403. The anti-loosening component 200 can reinforce the sealing cover 103 of the threaded connection, preventing the intake connector body 102 of the threaded connection from loosening and improving the stability of the gas booster pump intake connector.

[0037] Example 2

[0038] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the sealing cover 103 is provided with a compression structure 300. The compression structure 300 includes two sets of telescopic rods 301 disposed on the inner wall of the sealing cover 103. Each set of telescopic rods 301 is fitted with a connecting spring 302 on its outer wall.

[0039] The telescopic rod 301 has an arc-shaped block 303 fixedly connected to one end facing the metal filter 402. The mounting frame 401 has a circular groove 304 on the side facing the sealing cover 103, and the circular groove 304 and the arc-shaped block 303 are slidably arranged. Through the elasticity of the connecting spring 302, the arc-shaped block 303 can always move towards the end facing the metal filter 402. When the sealing cover 103 is threadedly installed with the air intake connector body 102, the arc-shaped block 303 rotates in the circular groove 304. With the elasticity of the connecting spring 302, the metal filter 402 and the glass fiber layer 403 are stably installed in the air intake connector body 102. When the sealing cover 103 is removed, the arc-shaped block 303 can be disengaged from the circular groove 304. After the mounting frame 401 is no longer restricted, the metal filter 402 and the glass fiber layer 403 can be removed and replaced.

[0040] The anti-loosening component 200 also includes a fixed cylinder 202 fixedly connected to the fixed base 201. An anti-detachment plate 204 is slidably connected inside the fixed cylinder 202, and the anti-detachment plate 204 is fixedly connected to the positioning rod 205.

[0041] A compression spring 203 is fixedly connected to the inner wall of the fixed cylinder 202. The end of the compression spring 203 facing the positioning rod 205 is fixedly connected to the anti-detachment plate 204. Through the elasticity of the compression spring 203, the positioning rod 205 can always move towards the end of the positioning hole 206.

[0042] The fixed base 201 has a slot 207, and a moving rod 208 is inserted through the slot 207 and fixedly connected to the positioning rod 205. The sliding of the moving rod 208 in the slot 207 can adjust the height of the positioning rod 205. When the sealing cover 103 needs to be threaded onto the air intake connector body 102, the moving rod 208 moves upward in the slot 207, causing the positioning rod 205 to move upward. At this time, the compression spring 203 is compressed. After the sealing cover 103 is threaded onto the air intake connector body 102, the positioning hole 206 is aligned with the positioning rod 205. After the moving rod 208 is released, the compressed spring 203 can automatically return to its original position, thereby driving the positioning rod 205 to move until it is connected with the positioning hole 206. This can prevent the threaded air intake connector from becoming loose.

[0043] The inner wall of the sealing cover 103 is provided with an internal thread section, and the outer wall of the air intake connector body 102 facing the sealing cover 103 is provided with an external thread section that matches the internal thread section.

[0044] The diameter of the mounting frame 401 is equal to the inner diameter of the air intake connector body 102, and the mounting frame 401 is connected to the fiberglass layer 403 via a connecting rod.

[0045] When in use, the inlet connector 104 is connected to the gas delivery pipe, and the outlet connector 105 outputs the pressurized gas. The metal filter 402 on the filter assembly 400 can intercept solid particles in the gas, and the glass fiber layer 403 can adsorb fine particles and droplets in the gas, ensuring the purity of the gas.

[0046] When the sealing cover 103 is threaded onto the intake connector body 102, the arc-shaped block 303 of the extrusion structure 300 rotates within the circular groove 304. Combined with the elasticity of the connecting spring 302, the metal filter 402 and the glass fiber layer 403 are stably installed within the intake connector body 102. After the sealing cover 103 is removed, the arc-shaped block 303 can disengage from the circular groove 304. Once the mounting frame 401 is no longer restricted, the metal filter 402 and the glass fiber layer 403 can be removed and replaced.

[0047] When the sealing cap 103 needs to be threaded onto the air intake connector body 102, the moving rod 208 on the anti-loosening component 200 moves upward in the slot 207, causing the positioning rod 205 to move upward. At this time, the compression spring 203 is compressed. After the sealing cap 103 is threaded onto the air intake connector body 102, the positioning hole 206 is aligned with the positioning rod 205. After the moving rod 208 is released, the compressed spring 203 can automatically return to its original position, thereby driving the positioning rod 205 to move until it is connected with the positioning hole 206, which can prevent the threaded air intake connector from becoming loose.

[0048] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
