Description

Technical Field

[0001] This utility model relates to the field of gas pipeline detection technology, and in particular to a gas pipeline pressure leak detector. Background Technology

[0002] Gas leaks can cause major safety accidents such as explosions and fires. By monitoring pipeline pressure changes in real time, leak risk points can be quickly identified, effectively preventing catastrophic accidents.

[0003] In the prior art, a search revealed a Chinese patent disclosed as "A Gas Pipeline Pressure Leakage Detector," application number "202121809947.9." This patent mainly includes a gas pipeline and a pressure sensing component. The gas pipeline includes a connecting pipe and a main pipe. One end of the connecting pipe is connected to the main pipe via a connecting nut. A limiting ring is provided on the inner wall of one end of the main pipe. One end of the connecting pipe is inserted into the main pipe and abuts against the limiting ring. A limiting platform is provided on the outer arm of the connecting pipe. The pressure sensing component includes a diaphragm, an adjusting knob, a top plug, a compression spring, and a pressure gauge. The diaphragm is screwed to the other end of the main pipe, and the valve is embedded in the middle of the diaphragm. While this detector can differentiate between pressure instability and leakage, it is not a definitive solution. However, the use of the aforementioned detectors relies on the connection between the connecting pipe and the gas pipe. Gas pipe leaks often occur at connections such as valves and flanges, which typically lack connecting pipes. This means the detector can only cover the area where the main pipeline has a connecting pipe. Furthermore, after the detector is connected to a fixed gas pipe location, the actual leak risk may be located in other unconnected pipe sections, requiring further inspection of subsequent leaks and increasing workload. Therefore, this invention provides a gas pipeline pressure leak detector to solve the problems mentioned in the background section. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses a gas pipeline pressure leak detector, which includes two adjacent gas pipes 1. At the connection point of the gas pipes 1, there are symmetrically arranged upper and lower covers 2 and 3. Both upper and lower covers 2 and 3 are semi-circular in structure and have folded edges at their ends. The upper and lower covers 2 and 3 are detachably connected by multiple evenly arranged connectors. A sealing ring 4 is fixed to the side of each upper and lower cover 2 and 3 near the gas pipe 1. A transparent plate 5 is embedded inside each upper and lower cover 3 to facilitate observation of air bubbles in the water. A water storage area is formed between the two sealing rings 4 and filled with water. A water injection pipe 9 and a drain pipe 6 are fixed inside the two transparent plates 5, respectively. Water is injected into the water storage area through the water injection pipe 9, and a valve 10 is provided on the outside of the drain pipe 6. Opening the valve 10 allows water to be discharged.

[0025] Based on the locations of potential leaks such as control valves and flanges on gas pipeline 1, the upper cover 2 and lower cover 3 are wrapped around the connection points, ensuring the sealing ring 4 fits snugly against the pipe wall. The bolts 8 are aligned with the mounting positions of the grooves 7, and the nuts are tightened to complete the sealing and form a sealed water storage area. Water is injected into the storage area until it submerges gas pipeline 1. The water condition in the storage area is observed through the transparent plate 5. If a leak is found at the connection point of gas pipeline 1, gas will pass through the water, forming continuous bubbles inside the storage area, thus enabling rapid leak identification and detection.

[0026] The device can quickly and easily identify leaks by visually displaying bubbles in the water in the storage area, with high sensitivity. At the same time, the semi-circular cover can be fitted with the gas pipe to complete the installation of the detection device, making it more suitable for connections such as control and flange connections, and highly practical.

[0027] The connecting parts are a bolt 8 and a nut that fit together, making the connection between the upper cover 2 and the lower cover 3 more stable and easier to assemble and disassemble. The ends of the upper cover 2, the lower cover 3 and the sealing ring 4 are all provided with grooves 7, and the bolt 8 is inserted into the groove 7. By setting the groove 7 to cooperate with the bolt 8, the bolt 8 can be easily disassembled and assembled by simply loosening the nut and pulling it out and inserting it from the side of the groove 7. This eliminates the troublesome problem of having to loosen the nut to separate the bolt 8, making it more convenient to use.

[0028] The sealing ring 4 has a wavy protrusion structure on the side facing the gas pipe 1. The sealing ring 4 is made of fluororubber. The continuous wavy protrusions form a labyrinth-like sealing structure, which ensures good sealing of the water storage area.

[0029] Both the upper cover 2 and the lower cover 3 are made of stainless steel to prevent them from coming into contact with residual water and causing corrosion. The bolt 8 has a Dacromet coating on the outside, which gives the connector good corrosion resistance.

[0030] Working principle: Based on the locations of potential leaks such as control valves and flanges on the gas pipeline 1, the upper cover 2 and lower cover 3 are wrapped around the connection points, ensuring the sealing ring 4 fits snugly against the pipe wall. The bolts 8 are aligned with the mounting positions of the grooves 7, and the nuts are tightened to complete the sealing and form a sealed water storage area. Water is injected into the storage area until it submerges the gas pipeline 1. The water condition in the storage area is observed through the transparent plate 5. If a leak is found at the connection point of the gas pipeline 1, the gas will pass through the water, creating continuous bubbles inside the storage area, thus enabling rapid leak identification and detection.

[0031] The device can quickly and easily identify leaks by visually displaying bubbles in the water in the storage area, with high sensitivity. At the same time, the semi-circular cover can be fitted with the gas pipe to complete the installation of the detection device, making it more suitable for connections such as control and flange connections, and highly practical.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
