The surfaces of the first pipeline and the second pipeline are fixedly connected to a fixing device, and a fixing seat is fixedly connected to the upper surface of one of the fixing devices.

[0004] However, existing gas pipeline installation connectors also have certain shortcomings. First, although existing gas pipeline installation connectors use structural components such as flanges and bolts to connect and install gas pipelines, the gas pressure is greatly affected by the environment. Simply using the connecting pipes for connection can easily cause high internal pressure problems.

[0005] Secondly, the existing gas pipeline installation connectors mostly use straight-through designs, making it difficult for operators to adapt the gas flow rate according to demand. Utility Model Content

[0006] The purpose of this utility model is to provide a gas pipeline installation connector, which solves the problem that existing gas pipeline installation connectors, although using flanges, bolts and other structural components to connect and install gas pipelines, are prone to internal high pressure due to the significant influence of the environment on gas pressure. Furthermore, it solves the problem that existing gas pipeline installation connectors mostly use straight-through designs for the connecting pipes, making it difficult for operators to adapt the gas flow rate according to demand.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas pipeline installation connector, comprising a connecting pipe, telescopic pipes fixedly connected to both ends of the connecting pipe, a flange fixedly connected to the other end of each telescopic pipe, an installation cylinder fixedly connected to the upper middle part of the connecting pipe, a driven shaft rotatably connected to the inner wall of the installation cylinder, the driven shaft rotatably connected to the connecting pipe, a sealing disc fixedly sleeved on the outer side of the driven shaft, and the sealing disc rotatably connected to the connecting pipe;

A pressure relief mechanism is provided on the connecting pipe.

[0009] Preferably, the upper end of the driven shaft is fixedly connected to an end head, which is rotatably connected to the mounting cylinder. The end head facilitates the user to push the driven shaft to rotate.

[0010] Preferably, a buckle is fixedly connected to the right end of the end plate. The buckle is made of rubber. The buckle facilitates the movement of the insertion rod by pulling it, and the rubber material has good skin-friendliness and durability.

[0011] Preferably, one end of the spring is welded to the mounting cylinder, and the other end of the spring is welded to the end plate. The end plate can be connected and used by means of the spring.

[0012] Preferably, the pressure relief mechanism includes a flow pipe. A flow pipe is fixedly connected to the inner wall of the connecting pipe and to the left side of the mounting cylinder. A fixed plate is fixedly connected to the inner wall of the flow pipe and to the upper side of the fixed plate. A telescopic rod is slidably connected to the inner wall of the fixed plate. A plug is fixedly connected to the lower end of the telescopic rod. The plug is slidably connected to the fixed plate. A second spring is provided on the outer side of the telescopic rod. Guide plates are fixedly connected to both sides of the plug. Each guide plate is slidably connected to the fixed plate. Through the deformation of the second spring, the plug can be pushed to seal the fixed plate, so as to ensure the sealing of the flow pipe under normal conditions.

[0013] Preferably, support plates are fixedly connected to the upper left and right sides of the flow pipe, and a rain cap is fixedly connected to the upper end of the two support plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model drives the driven shaft to rotate by pushing the end head, thereby driving the sealing disc to rotate. With the insertion hole, insertion rod and other structures, the driven shaft can be limited, so that the sealing disc is stable after adjusting the opening and closing angle, and the gas flow can be adjusted.

[0017] 2. This utility model, through the setting of structures such as telescopic pipes and flanges, can be used to connect and install gas pipelines. Under the impact of high-pressure gas, and with the deformation of spring two, the plug can be disengaged from the fixed plate, thereby making the flow pipe automatically open and automatically depressurize the gas.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A gas pipeline installation connector includes a connecting pipe 1, with telescopic pipes 2 fixedly connected to both ends of the connecting pipe 1, and a flange 3 fixedly connected to the other end of each telescopic pipe 2. An installation cylinder 4 is fixedly connected to the upper middle part of the connecting pipe 1, and a driven shaft 5 is rotatably connected to the inner wall of the installation cylinder 4. The driven shaft 5 is rotatably connected to the connecting pipe 1, and a sealing disc 6 is fixedly sleeved on the outer side of the driven shaft 5. The sealing disc 6 is rotatably connected to the connecting pipe 1.

[0026] The driven shaft 5 has an insertion hole 8 on its surface. The inner wall of the mounting cylinder 4 is slidably connected to the insertion rod 9. The insertion rod 9 is slidably connected to the insertion hole 8. The right end of the insertion rod 9 is fixedly connected to the end plate 10. A spring 11 is provided on the outside of the insertion rod 9.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The driven shaft 5 is fixedly connected to the upper end of the end head 7, which is rotatably connected to the mounting cylinder 4. The end head 7 makes it easy for the user to push the driven shaft 5 to rotate. The right end of the end plate 10 is fixedly connected to a buckle made of rubber. The buckle makes it easy to pull the insertion rod 9 to move. The rubber material has good skin-friendliness and durability. One end of the spring 11 is welded to the mounting cylinder 4, and the other end of the spring 11 is welded to the end plate 10. The end plate 10 can be connected and used through the spring 11.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A pressure relief mechanism 12 is provided on the connecting pipe 1. The pressure relief mechanism 12 includes a flow pipe 121. The flow pipe 121 is fixedly connected to the inner wall of the connecting pipe 1 and to the left side of the mounting cylinder 4. A fixed plate 123 is fixedly connected to the inner wall of the flow pipe 121 and to the upper side of the fixed plate 123. A telescopic rod 125 is slidably connected to the inner wall of the fixed plate 124. A plug 126 is fixedly connected to the lower end of the telescopic rod 125. The plug 126 is slidably connected to the fixed plate 123. A spring 127 is provided on the outer side of the telescopic rod 125. Guide plates 128 are fixedly connected to both sides of the plug 126. Each guide plate 128 is slidably connected to the fixed plate 124. Through the deformation of the spring 127, the plug 126 can be pushed to seal the fixed plate 123 to ensure the sealing of the flow pipe 121 under normal conditions.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4Support plates are fixedly connected to the upper left and right sides of the flow pipe 121. The upper ends of the two support plates are fixedly connected to the rain cap 122. The rain cap 122 is located directly above the flow pipe 121.

The second spring 127 can be used to tighten the plug 126.

[0030] The specific implementation process of this utility model is as follows: In use, the position of the flange 3 can be adjusted by setting the telescopic tube 2 so that the flange 3 contacts the end of the gas pipeline to be connected, and the flange 3 and the gas pipeline are locked together with the bolts to complete the connection of the gas pipeline.

[0031] By pulling the retaining ring to the right, the end plate 10 is moved, which in turn moves the insertion rod 9. The spring 11 deforms, causing the insertion rod 9 to disengage from the insertion hole 8. Then, the end 7 is pushed to rotate, which in turn rotates the driven shaft 5, which in turn rotates the sealing disc 6. The opening and closing angle of the sealing disc 6 is adjusted. The retaining ring is then released, causing the spring 11 to deform, which pulls the insertion rod 9 to insert into the next insertion hole 8 on the surface of the driven shaft 5. The driven shaft 5 is limited, so that the sealing disc 6 is stable after adjustment, and the flow of gas is adaptively adjusted.

[0032] When high-pressure gas impacts the plug 126, the plug 126 pushes the telescopic rod 125 to slide along the inner wall of the fixed plate 124, the spring 127 deforms, and when the plug 126 moves, it can drive the guide plate 128 to slide along the inner wall of the fixed plate 124 to ensure the stability of the movement of the plug 126. Finally, the plug 126 is separated from the fixed plate 123, so that the flow pipe 121 is in a flow state, and the high-pressure gas is automatically depressurized. Under the action of the rain cap 122, the flow pipe 121 can be protected to avoid the intrusion of water and other substances.
