Description

Technical Field

[0041] The connecting sealing mechanism includes a fixed tube 3, a first spring 4 is movably connected to the outside of the fixed tube 3, a plurality of limiting balls 5 are movably connected to the inside of the fixed tube 3, and the plurality of limiting balls 5 are evenly distributed inside the sealing gasket 2; a clamping ring 6 is movably connected to the outside of the fixed tube 3, a limiting groove 7 is arranged on one side of the clamping ring 6, and two guide grooves 8 are arranged at the bottom of the clamping ring 6, and the two guide grooves 8 are symmetrically distributed at the bottom of the clamping ring 6; an air intake pipe 9 is movably connected to the inner wall of the fixed tube 3, and two clamping grooves 10 are arranged on the outside of the air intake pipe 9; a plurality of second springs 11 are fixedly connected to one side of the inside of the air intake pipe 9, and a connecting ring 12 is fixedly connected to one side of the plurality of second springs 11; the clamping ring 6 allows the plurality of limiting balls 5 to be retracted into the inside of the fixed tube 3 through the two guide grooves 8 at the bottom, so that the air intake pipe 9 is inserted into the inside of the fixed tube 3 conveniently; at the same time, the second spring 11 pushes the connecting ring 12 to fit the sealing gasket 2 on the other side of the main pipeline 1, so that the main pipeline 1 and the air intake pipe 9 are connected, reducing the possibility of air leakage.

[0042] Reference Figure 3 As shown, specifically, a pressure sensor 13 is fixedly connected to one side of the top of the main pipeline 1 to monitor the pressure inside the main pipeline 1 .

[0043] Reference Figure 4 As shown, specifically, a buffer box 14 is fixedly connected to the rear side of the main pipeline 1, two clamp rings 15 are movably connected to one side of the buffer box 14, and bolts 16 are movably connected to the front sides of the two clamp rings 15, so that the buffer box 14 can be stably fixed on the outside of the main pipeline 1.

[0044] Reference Figure 4 As shown, specifically, a pressure relief pipe 17 is fixedly connected to the top of the buffer box 14, an electric-controlled ball valve 18 is fixedly connected to the outside of the pressure relief pipe 17, a water suction pipe 19 is fixedly connected to the bottom side of the buffer box 14, a plurality of water mist nozzles 20 are fixedly connected to the top of the water suction pipe 19, and a filter screen 21 is fixedly connected to the other side of the buffer box 14, so that the fuel gas discharged into the buffer box 14 can be processed to a certain extent before being discharged to the outside, thereby improving a certain degree of safety.

[0045] Reference Figure 1 As shown, specifically, a water inlet pipe 22 is fixedly connected to the other side of the top of the buffer box 14 , and a pipe cover 23 is movably connected to the top of the water inlet pipe 22 , so as to facilitate adding water into the buffer box 14 .

[0046] The working principle of the utility model is as follows: before delivering the fuel gas, the clamp ring 6 is first pushed to one side so that the clamp ring 6 squeezes the first spring 4, and the two guide grooves 8 at the bottom of the clamp ring 6 are aligned with the tops of the two rows of limiting balls 5 inside the fixed tube 3, and then the intake pipe 9 is inserted into the first spring 4, and the outer wall of the intake pipe 9 squeezes the multiple limiting balls 5 so that the multiple limiting balls 5 are squeezed into the fixed tube 3. When the front end connecting ring 12 of the intake pipe 9 is fitted with the sealing gasket 2 on the other side of the main pipeline 1, the multiple second springs 11 support the connecting ring 12, so that the sealing gasket 2 is in the intake pipe 9. The interior can fit closely with the connecting ring 12. Later, when the fuel gas is transported, the pressure sensor 13 will detect the gas pressure inside the main pipeline 1. When the internal pressure of the main pipeline 1 is relatively high, the electric control ball valve 18 will open, and the higher pressure inside the main pipeline 1 will enter into the buffer box 14 through the pressure relief pipe 17. The interior of the buffer box 14 can be filled with water through the water inlet pipe 22. The water suction pipe 19 and the water mist nozzle 20 spray the water into water mist, and perform certain treatment on the fuel gas entering the buffer box 14. Finally, the higher pressure inside the main pipeline 1 is discharged through the filter 21.
