Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment 1:

[0023] Please refer to Figures 1-5 A kind of main pipe with cap stainless steel gas collecting pipe assembly, including gas collecting main pipe 1, pipe cap 11 is welded on one end of gas collecting main pipe 1, connecting branch pipe 12 is fixedly arranged on gas collecting main pipe 1, flange plate one 13 is fixedly arranged on connecting branch pipe 12, connecting piece 3 is connected on flange plate one 13, connecting piece 3 includes main body 31, main body 31 is circular table, connecting disc one 32 and connecting disc two 33 are fixed to the two ends of main body 31 respectively, connecting disc one 32 is connected with flange plate one 13, connecting disc two 33 is connected with flange plate two 21, flange plate two 21 is fixedly installed on one end of gas collecting branch pipe 2;

[0024] Round hole one 131 is arranged in annular array on flange plate one 13, connecting ring one 14 is fixedly installed on one end of connecting branch pipe 12 close to connecting piece 3;

[0025] Round hole two 22 is arranged in annular array on flange plate two 21, connecting ring two 23 is fixedly installed on one end of gas collecting branch pipe 2 close to connecting piece 3;

[0026] Both connecting plate 1 32 and connecting plate 2 33 are provided with rotating grooves 34. A rotating component 35 is rotatably installed in the rotating groove 34. A spiral rod 36 is fixedly installed on one end of the rotating component 35. A locking nut 37 is screwed onto the spiral rod 36. The spiral rod 36 on connecting plate 1 32 is adapted to the corresponding hole 131, and the spiral rod 36 on connecting plate 2 33 is adapted to the corresponding hole 22.

[0027] Specifically, the spiral rod 36 on the connecting plate 32 corresponds to the circular hole 131 on the flange 13. The spiral rod 36 is passed through the circular hole 131, and then the locking nut 37 on the spiral rod 36 is rotated to make the connecting plate 32 and the flange 13 tightly connected together. Similarly, the spiral rod 36 on the connecting plate 33 corresponds to the circular hole 22 on the flange 21. The connecting plate 33 and the flange 21 are connected by passing the spiral rod 36 through the circular hole 22 and tightening the locking nut 37.

[0028] Using connector 3 to connect the main gas collecting pipe 1 and the branch gas collecting pipe 2 allows the main gas collecting pipe 1 to be manufactured according to a uniform specification and process. It eliminates the need to design a separate flange for each branch pipe with a different diameter, reducing a large amount of dimensional calculation and drawing work in the design process, shortening the design cycle. Connector 3 can also be produced in a standardized manner, improving production efficiency, reducing production costs, and ensuring the stability of product quality.

[0029] Regardless of the diameter of the gas collecting branch pipe 2, as long as the appropriate connector 3 is selected, it can be connected to the gas collecting main pipe 1. This allows the gas collecting main pipe 1 and connector 3 to be used as common components in different projects, which facilitates product inventory management and allocation. When a branch pipe or connector 3 is damaged, it is also easier to find a suitable replacement part, reducing maintenance costs and time.

[0030] At the construction site, installers do not need to spend a lot of time matching and installing flanges of different sizes. They only need to select the corresponding connector 3 according to the diameter of the branch pipe to quickly connect the gas collecting branch pipe 2 and the gas collecting main pipe 1, which improves construction efficiency and shortens the construction cycle.

[0031] Example 2:

[0032] To improve the sealing of the connection, please refer to Figures 1-5 Based on embodiment 1, a connecting groove 321 is provided on one end of the main body 31 near the connecting branch pipe 12.

When the connecting ring one 14 is inserted into the connecting groove one 321 and the connecting ring two 23 is inserted into the connecting groove two 331, the sealing washer is deformed by extrusion, fills the small gap between the connecting ring and the connecting groove, prevents gas or liquid from leaking from the gap, and thus plays a sealing role. The connecting groove one 321 and the connecting ring one 14 correspond to each other, the connecting groove two 331 and the connecting ring two 23 correspond to each other, and accurate fitting ensures the tightness of the connection. The connecting ring can be accurately embedded in the connecting groove, so that the sealing washer is uniformly extruded in the appropriate position, the sealing effect is guaranteed, the leakage of gas or liquid in the gas collecting pipe is effectively prevented, the sealing performance and reliability of the gas collecting pipe assembly are improved, normal operation under various working conditions is ensured, and safety hazards and resource waste caused by leakage are reduced.

[0035] Working principle: according to the diameter of the gas collecting branch pipe 2 to be installed, select the appropriate connecting piece 3, pass the screw rod 36 on the connecting disc one 32 through the round hole one 131 on the flange disc one 13, then rotate the locking nut 37 on the screw rod 36, tightly connect the connecting disc one 32 and the flange disc one 13, thereby connecting the connecting piece 3 to the connecting branch pipe 12 of the gas collecting main pipe 1, correspond the round hole two 22 on the flange disc two 21 at one end of the gas collecting branch pipe 2 to the screw rod 36 on the connecting disc two 33, pass the screw rod 36 through the round hole two 22, and then tighten the locking nut 37 to realize the connection between the gas collecting branch pipe 2 and the connecting piece 3.

[0036] In the process of connecting the connecting piece 3 with the gas collecting main pipe 1 and the gas collecting branch pipe 2, the connecting ring one 14 is inserted into the connecting groove one 321, and the connecting ring two 23 is inserted into the connecting groove two 331, so that the sealing washer is deformed by extrusion and fills the small gap between the connecting ring and the connecting groove, thereby playing a sealing role.
