Embodiment 1

[0023] The present invention provides such Figure 1-4 The joint of a welded gas meter shown includes a joint main body 1, and a top connecting seat 2 and a bottom connecting seat 3 are arranged inside the joint main body 1, and the top connecting seat 2 and the bottom connecting seat 3 communicate with each other and the bottom The bottom of the connecting seat 3 is provided with a limit collar 4, and the outer sides of the top connecting seat 2 and the bottom connecting seat 3 are provided with a bearing seat 5, and the outer side of the bearing seat 5 is surrounded by an annular gap 6, and the bottom of the bearing seat 5 has two Each end is provided with a bottom joint seat 7, and both ends of the top of the bearing seat 5 are provided with a top joint seat 8.

[0024] Further, the top connection seat 2, the bottom connection seat 3, the limit collar 4 and the bearing seat 5 are integrally arranged, and the bottom joint seat 7 and the top joint seat 8 are integrally arrang...

Embodiment 2

[0029] Further, the inner walls of the top connecting seat 2, the bottom connecting seat 3 and the limiting collar 4 are all provided with connecting threads, and the limiting collar 4 is arranged around the outer side of the bottom connecting seat 3 and is arranged on the two bottoms. Between the joint seat 7.

[0030] Further, the annular notch 6 is arranged around the outer side of the bearing seat 5, and the bearing seat 5 is made of alloy material.

[0031] Beneficial effects of this embodiment: installation is carried out through the top connecting seat 2 and the bottom connecting seat 3, and after the installation is completed, the welding connection is performed again through the outer bottom joint seat 7 to ensure that the internal position is stable and can be connected by the outer socket The ring is clamped inside the annular notch 6, and is double stabilized from the inside and the outside to ensure overall stability.

Embodiment 3

[0033] Further, the number of the bottom joint seats 7 is set to two, and the two bottom joint seats 7 are fixedly connected without chamfering. The angle in the horizontal direction is 9°.

[0034] Beneficial effects of this embodiment: the angle between the bottom joint seat 7 and the joint body 1 in the horizontal direction is set to 9°, which can ensure that there is no gap or a very small gap between the joints during connection, and the angle of the joint is different from that of the joint body 1. Surface contact, the basic principle of resistance welding will not be violated during the welding process, that is, line contact between the welded parts must be achieved, which ensures high welding strength, and can not only eliminate the welding gap, but also ensure the best welding strength, and the structure is simple , easy to realize, just change the processing program on the original CNC processing equipment, without changing the shape and weight of the original blank,...

Abstract

The invention discloses a joint of a welded gas meter, specifically relates to the field of joint equipment, comprising a joint body, a top connection seat and a bottom connection seat are arranged inside the joint body, and the top connection seat and the bottom connection seat communicate with each other And the bottom of the bottom connecting seat is provided with a limit collar, the outer sides of the top connecting seat and the bottom connecting seat are provided with a bearing seat, the outer side of the bearing seat is surrounded by an annular gap, and both ends of the bottom of the bearing seat are provided with bottom joints seat. In the present invention, by providing the bottom joint seat, the angle between the bottom joint seat and the joint main body in the horizontal direction is set to 9°, which can ensure that there is no gap or a very small gap between the joints during connection, and the angle of the joint is different from that of the joint main body. Surface contact, the basic principle of resistance welding will not be violated during the welding process, that is, line contact between welded parts must be achieved, which ensures high welding strength, and can not only eliminate welding gaps, but also ensure optimal welding strength.

Description

technical field [0001] The invention relates to the technical field of connector equipment, and more specifically, the invention relates to a connector of a welded gas meter. Background technique [0002] The surface treatment process of the welded structure shell of the welded joint is plastic spraying, which requires no gap or a very small gap (less than 0.05mm) between the shell and the joint. Therefore, it is necessary to ensure the welding strength and the required shell during use. There is no gap or a very small gap (less than 0.05 mm) between the joint and the joint, which has become a difficult problem for us to solve. [0003] The gap between the original welded joint and the shell after welding is 1 mm, and the gap cannot be covered after powder spraying, which can easily cause corrosion of the weld seam, reduce the service life of the gas meter, and increase safety hazards. Contents of the invention [0004] In order to overcome the above-mentioned defects of ...
