Description

Technical Field

[0001] The utility model relates to the technical field of gas leakage detection, in particular to a gas leakage detection device for a gas release pipeline. Background Art

[0002] The vent pipe is a device specially used to discharge the air or gas inside the pipeline. When the pipeline is put into operation, the vent pipe is used to discharge the air in the pipe. When the pipeline or equipment is under maintenance, the vent pipe can be used to discharge the gas in the pipe to prevent the formation of explosive mixed gas in the pipeline. Its function is to provide overpressure protection for downstream equipment. The pressure is relatively high. In recent years, gas leaks in the vent pipes of plants and stations have occurred frequently, and valves in the upstream distribution stations often leak.

[0003] At present, gas leakage in the vent pipeline is discovered only after the on-duty personnel visually inspect the frosting of the pipeline at the rear end of the valve. In addition, human error, impurities brought by the pipeline, and hardening of grease will cause internal leakage of the valve. The initial design of the vent pipeline did not consider installing a leakage detection device at this end. Manual detection has poor effectiveness and cannot be online 24 hours a day, which easily leads to gas loss in the vent pipeline. Utility Model Content

The initial design of the venting pipeline did not consider installing a leak detection device at this end. Manual detection has poor effectiveness and cannot be online 24 hours a day, which easily leads to the problem of gas loss in the venting pipeline.

[0007] Furthermore, a flame arrester is arranged on the branch pipe, and a one-way valve is arranged on the branch pipe and on the left side of the flame arrester.

[0008] Furthermore, the exterior of the emission tower body is fixedly mounted on a connecting plate, and a collector electrically connected to the gas probe is fixedly mounted on the connecting plate.

[0009] Furthermore, a mounting hole adapted to the gas probe is provided on the mounting plate, and a sliding groove adapted to the slide plate is provided on the top of the mounting plate.

[0010] Furthermore, the two slide plates are both "T"-shaped plates, and the separated surfaces of the two slide plates are both provided with slots adapted to the insertion rods.

[0011] Furthermore, one end of the spring is connected to the inner side wall of the mounting plate, and the other end is connected to the compression block.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The gas leakage detection device for the venting pipeline is provided with a gas probe, a detection port is opened at the branch pipe connection at the front end of the venting tower body, and the gas probe is installed at the detection port. The cooperation between the gas probe and the collector can detect the leakage of the gas passing through the point in real time, and the information can be sent back to the customer or mobile phone.

[0014] 2. The gas leak detection device for the easy-to-release pipeline is provided with an insertion rod.

The compression block moves the compression spring to store force, and the insertion rod moves to the inside of the movable cavity. Then, the slides on the left and right sides of the gas probe are inserted into the slide grooves inside the mounting plate. Then, the insertion rod is released to allow the spring to rebound after being free from pressure and drive the compression block to move. The movement of the compression block drives the insertion rod to move and insert into the inside of the slide, so that the slide is fixed inside the mounting plate. The same is true when disassembling, thereby making the gas probe easy to disassemble and assemble quickly. BRIEF DESCRIPTION OF THE DRAWINGS

The interior of the mounting plate 6 and the separated surfaces of the two slide plates 801 are provided with movable cavities 802. When the gas probe 7 needs to be installed, the two insertion rods 803 are first pulled to move them to drive the compression block 804 to move. The compression block 804 moves the compression spring 805 to store force, and the insertion rod 803 moves to the movable cavity 802. Internally, on the left and right sides of the mounting plate 6, there are movably mounted insertion rods 803 that penetrate the movable cavity 802 and extend to the inside of the slide plate 801. A compression block 804 is fixedly mounted on the outside of the insertion rod 803. A spring 805 is sleeved on the outside of the insertion rod 803. When the insertion rod 803 is loosened, the spring 805 rebounds after being free from pressure, and drives the compression block 804 to move. The movement of the compression block 804 drives the insertion rod 803 to move and insert into the inside of the slide plate 801, so that the slide plate 801 is fixed to the inside of the mounting plate 6, thereby facilitating the quick disassembly and assembly of the gas probe 7.

[0027] 3) Insert the slide plates 801 on the left and right sides of the gas probe 7 into the slide grooves inside the mounting plate 6;

[0028] 4) Loosen the rod 803 again to allow the spring 805 to rebound after being freed from pressure, and drive the compression block 804 to move;

[0029] 5) Finally, the compression block 804 moves to drive the insertion rod 803 to move and insert into the inside of the slide plate 801, so that the slide plate 801 is fixed inside the mounting plate 6, so that the gas probe 7 is easy to install quickly.
