[0024] See also Figures 1 to 3 The utility model provides a joint base for a gas storage tank with a filtering function, comprising a first part 2 and a second part 3. The first part 2 is a side of the joint base connected to the gas storage tank 1; the second part 3 is a side of the joint base with a mounting channel 30, and a filter 4 with a filtering function is installed in the mounting channel 30. The cross-sectional profile of the side of the first part 2 connected to the gas storage tank 1 is circular. The mounting channel 30 and the filter 4 are connected by threads.

[0025] Specifically, in the embodiment of the utility model, the filter 4 is assembled through the installation channel 30 opened in the joint base, so as to realize the gas filtering function of the connected gas tank 1 and maintain its cleanliness requirements. The filter 4 is assembled into the installation channel 30 by means of threaded connection, and the filter 4 can be replaced by direct disassembly to maintain the filtering performance of the filter 4 in accordance with the cleanliness requirements of the gas tank 1 system. At the same time, the first part 2 on the joint base connected to one side of the gas tank 1 is set to a circular cross-sectional profile, so that it matches the gas tank 1 which generally has a circular cross-sectional profile, so as to facilitate the installation and connection of the joint base to the gas tank 1 (for example, by welding, the gas tank 1 which has a circular profile and the first part 2 of the joint base can be completely in contact with each other in the circumference for welding). By making the bottom of the joint base cylindrical, it is convenient to assemble and weld with the gas tank 1 (see attached Figure 2 The installation channel 30 is provided on the top of the joint base for installing the filter tip 4, and the filter tip 4 is threaded for easy disassembly and maintenance (see attached Figure 3 ).

[0026] See also Figure 2 In one embodiment, the cross-sectional profile of the second portion 3 is not larger than the cross-sectional profile of the first portion 2 , and at least one pair of parallel surfaces 31 is provided on the cross-sectional profile of the second portion 3 .

[0027] Specifically, the joint base is connected and fixed to the gas tank 1 through its first part 2, and is connected to other structural parts such as the air pipe joint through its second part 3. Therefore, a parallel surface 31 is set on the cross-sectional profile of the second part 3 for assembling the air pipe joint and other parts connected to the joint base. Four parallel-sided planes are set on the cross-sectional profile of the second part 3 to serve as clamping surfaces for assembling other connecting parts. The four sides of the second part 3 in the joint base are designed to be four squares or two squares, which is convenient for installing various connecting joints (see the attached Figure 2 ); The same method can also be used to set two parallel sides of the plane, which will not be described here.

[0028] See also Figure 2 and Figure 3 In one embodiment, the cross-sectional dimension of the airflow channel 32 of the joint base at the first part 2 is greater than the cross-sectional dimension at the second part 3. The airflow channel 32 of the second part 3 includes a first flow channel 321 connected to the airflow channel 32 of the first part 2 and a second flow channel 322 connected to the outside, and the first flow channel 321 is arranged along the axial direction of the second part 3, and the second flow channel 322 is arranged along the radial direction of the second part 3.

[0029] Specifically, the size of the joint base is smaller than that of the gas tank 1, so the size of the air flow channel 32 of the first part 2 of the joint base is set larger to cover the air hole of the gas tank 1, ensuring the connection effect with the gas tank 1. At the same time, in the second part 3 of the joint base, the air flow channel 32 is divided into two second flow channels 322 from the first flow channel 321 connected to the first part 2, and the opening of the formed second flow channel 322 in the second part 3 is located on the radial plane contour thereof, so as to be directly connected with the air pipe interface installed on the plane.

[0030] Furthermore, the installation channel 30 is opened in the axial direction of the second portion 3, and is connected to the first flow channel 321 and the second flow channel 322, and the opening of the installation channel 30 is located at the top of the second portion 3. The cross-sectional size of the installation channel 30 is larger than the cross-sectional size of the first flow channel 321, and the bottom of the installation channel 30 extends into the first flow channel 321 below the second flow channel 322.

[0031] More specifically, in the embodiment of the utility model, the installation channel 30 opened along the axial direction of the joint base, that is, the second part 3 thereof, overlaps with the first flow channel 321 which is also arranged axially, and forms a connection in the second part 3. In this way, the installed filter 4 is located in the installation channel 30, that is, above the first flow channel 321, so that the gas entering the first flow channel 321 from the gas storage tank 1 needs to pass through the filter 4 before entering the second flow channel 322. By setting the cross-sectional size of the installation channel 30 larger than the cross-sectional size of the first flow channel 321, on the one hand, as a space for threaded connection between the filter 4 and the installation channel 30, it avoids affecting the cross-sectional area of ​​the gas flow channel, and on the other hand, a step is formed between the bottom end of the installation channel 30 and the first flow channel 321 to ensure that the filter 4 is installed and positioned accurately.

[0032] See also Figure 2 and Figure 3 In one embodiment, the filter 4 includes a body 40, an end cover 41 and a filter element 42. The cross-sectional size of the body 40 matches the cross-sectional size of the installation channel 30; the end cover 41 is installed at the top of the body 40 and is larger than the cross-sectional size of the body 40, and a sealing ring 410 is sleeved on the body 40 at the bottom of the end cover 41; the filter element 42 is installed at the bottom of the body 40 and is located at the bottom end of the installation channel 30.

[0033] Furthermore, the distance between the bottom end of the installation channel 30 and the port where the second flow channel 322 communicates with the first flow channel 321 is greater than the height of the filter element 42 .

[0034] Specifically, the structure of the filter 4 can be composed of an end cap 41 on the body 40, a sealing ring 410 and a filter element 42 having a filtering function. The filter element 42 is arranged at the bottom of the filter 4 so as to be located at the bottom of the installation channel 30, so that the filter element 42 is installed in the first flow channel 321, so that the gas entering the second flow channel 322 and then flowing to the outside needs to be filtered by the filter element 42. In other words, the filter element 42 through which the gas flows is both the top position of the first flow channel 321 and the bottom position of the installation channel 30. At the same time, the height dimension relationship between the filter element 42 and the bottom position of the installation channel 30 is set in coordination, so that the filter element 42 is completely located in the space of the first flow channel 321, so that the gas coming out of the gas storage tank 1 is first filtered by the filter 4, thereby obtaining air that meets the cleanliness requirements.

[0035] In summary, the utility model provides a joint base for a gas tank with a filtering function, which adds a mounting channel on the joint base of the gas tank for installing a filter tip, so that the gas coming out of the gas tank is first filtered by the filter tip, thereby obtaining air that meets the cleanliness requirements.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
