[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1-5The present invention relates to a gas pipeline pressure testing assembly, which is equipped with a synchronous docking mechanism. The synchronous docking mechanism enables the gas pipe 7 to dock with the docking branch pipe 4, allowing multiple gas pipes 7 to be docked and tested simultaneously, thus greatly improving the efficiency of docking testing and enabling simultaneous pressure testing of multiple gas pipelines. The specific structural configuration of the synchronous docking mechanism is as follows.

[0022] In this technical solution, as shown in the appendix Figure 1-2 As shown, the connecting pipe 2 is fixedly connected to one end, and the docking hole plate 3 is fixedly installed at one end of the connecting pipe 2. The characteristic feature is that a synchronous docking mechanism is provided on one side of the docking hole plate 3; the synchronous docking mechanism includes multiple docking branch pipes 4 fixedly disposed on one side of the docking hole plate 3, and a sealing ring 5 is squeezed and connected to one end of each docking branch pipe 4. A compression ring 6 is bonded to one side of the sealing ring 5, and a gas pipe 7 is fixedly installed on the inner wall of the compression ring 6. A synchronous pressure groove plate 8 is provided on the outer wall of the gas pipe 7; a pressure rod 9 is fixedly connected to one side of the synchronous pressure groove plate 8 near its center point, and an electric cylinder 10 is fixedly installed at one end of the pressure rod 9. The multiple docking branch pipes 4 are all connected to the docking hole plate 3, and the multiple docking branch pipes 4 are arranged in a circular, equidistant distribution. The vertical cross-section of each docking branch pipe 4 is circular. The multiple gas pipes 7 are all slidably connected to the synchronous pressure groove plate 8, and the multiple gas pipes 7 are arranged in a circular, equidistant distribution.

[0023] In this technical solution, as shown in the appendix Figure 2-3 As shown, a reinforcing frame 11 is fixedly installed on one side of the electric cylinder 10. Support columns 12 are fixedly connected to one side of the reinforcing frame 11 and near both ends. Both support columns 12 are fixedly connected to the docking plate 3 to support the reinforcing frame 11, increasing its stability. The reinforcing frame 11 provides support to the electric cylinder 10, preventing it from shaking. A pressure gauge 13 is fixedly installed on the top of the outer wall of the pressure pipe 1, and a support plate 14 is fixedly connected to one side of the pressure gauge 13. The support plate 14 is fixedly connected to the pressure pipe 1, allowing multiple docking branch pipes 4 to enter multiple gas pipes 7 for pressurization. The pressurization value is displayed on the pressure gauge 13, and the support plate 14 provides support to the pressure gauge 13, significantly increasing its stability.

[0024] When in use, the gas pipeline pressure testing assembly of this technology uses a docking plate 3 to support two support columns 12, which in turn support a reinforcing frame 11, increasing the stability of the reinforcing frame 11. The reinforcing frame 11 supports an electric cylinder 10, which pushes the pressure rod 9 to the left. The pressure rod 9 drives the synchronous pressure groove plate 8 to the left, which in turn drives multiple compression rings 6 to move to the left. The compression rings 6 cause the sealing ring 5 to move to the left, and the sealing ring 5 is pressed against the docking branch pipe 4 to achieve a sealing operation. Multiple synchronous pressure groove plates 8 can simultaneously compress multiple compression rings 6, allowing the gas pipe 7 to form a docking operation with the docking branch pipe 4. In this way, multiple gas pipes 7 are connected to multiple docking branch pipes 4 respectively, multiple docking branch pipes 4 are connected to the docking plate 3, the docking plate 3 is connected to the docking pipe 2, and the docking pipe 2 is connected to the pressure testing pipe 1.

A support ring 19 is fixedly installed on the outer wall of the filter element 18. The booster pump 16 is used to pressurize the air, and the booster pipe 17 is connected to the booster pump 16.

[0026] In use, this technology first seals the right ends of multiple gas pipes 7 with sealing material. Then, a booster pump 16 introduces pressurized air into the booster pipe 17. The booster pipe 17 supports a support ring 19, which in turn supports a filter element 18. This allows the air filtered by the filter element 18 to quickly enter the booster pipe 17. After being pressurized by the booster pipe 17, the air enters the valve 15. Opening the valve 15 allows the pressurized air to enter the pressure-pressurizing pipe 1, then the connecting pipe 2, and finally the connecting plate 3. The connecting plate 3 then leads to multiple connecting branch pipes 4, which in turn pressurize the multiple gas pipes 7. The pressurized pressure is displayed on a pressure gauge 13. The pressure-pressurizing pipe 1 supports a support plate 14, which in turn supports the pressure gauge 13, which displays the pressure reading.
