Description

Technical Field

[0002] Chemical engineering is the foundation of modern industry. The application of chemical engineering technology utilizes a series of chemical principles to produce inorganic salts, acids, alkalis, rare metals, synthetic fibers, plastics, synthetic rubber, fuels, paints and other chemical raw materials. During the production process, due to the chemical reaction, some special production materials will release gases after the reaction, which may include halogen gases, halogen compound gases, organic and inorganic gases, nitrogen oxides, dust and so on.

[0003] In chemical production processes, pipelines are frequently used to transport toxic gases. Two pipelines are often connected by flanges. Over time, leaks inevitably occur at the connection between the two flanges for various reasons. To prevent leaked toxic and harmful gases from affecting the safety and health of workers and polluting the environment, it is necessary to regularly check for gas leaks at the flange connection. However, traditional gas pipeline leak alarm devices can only detect and alarm, and cannot take immediate action when a gas leak occurs, thus failing to provide valuable time for workers to carry out emergency repairs.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 4 As shown, an embodiment of this utility model provides a chemical gas leak detection device, including a sealing kit 1, an automatic sealing device 2, and a detection component 3. The automatic sealing device 2 is disposed inside the sealing kit 1, and the detection component 3 is detachably installed on the top of the sealing kit 1.

[0025] like Figure 3 As shown, the sealing kit 1 includes a fixed sleeve 11, a first rubber sleeve 12, and a pipe clamp 13. Both ends of the fixed sleeve 11 are fixedly connected to the first rubber sleeve 12, and both ends of the pipe clamp 13 are movably fitted onto the outer surface of the first rubber sleeve 12. A bottom frame 110 is fixedly installed at the bottom of the fixed sleeve 11. Ventilation slots 111 are provided on both sides of the bottom frame 110. The fixed sleeve 11 is installed on the pipe by fitting the pipe clamp 13 onto the outer surface of the first rubber sleeve 12. The sealing kit 1 is quickly installed on the outer surface of the pipe by the action of the pipe clamp 13, making the installation of the device more convenient.

[0026] like Figure 4As shown, the automatic sealing device 2 includes a miniature air pump 21, a fixing ring 23, and an airbag 24. Both ends of the miniature air pump 21 are fixedly connected to a connecting air tube 22. One side of the connecting air tube 22 is fixedly installed with the fixing ring 23. The inner wall of the fixing ring 23 is fixedly installed with the airbag 24. The airbag 24 is connected to one end of the connecting air tube 22.

[0027] The inner sides of both ends of the fixed sleeve 11 are fixedly installed with second rubber sleeves 18. Multiple deployment springs 19 are fixedly connected to the outer surface of the end of the second rubber sleeve 18 away from the first rubber sleeve 12. The other end of the multiple deployment springs 19 is fixedly connected to the inner wall of the fixed sleeve 11. The first rubber sleeve 12 is connected to the second rubber sleeve 18. Due to the action of the deployment springs 19, the interior of the second rubber sleeve 18 is supported, which makes it easy for the first rubber sleeve 12 and the second rubber sleeve 18 to fit onto the outer surface of the pipe. This prevents the second rubber sleeve 18 from folding during the fitting process of the sealing kit 1, which would affect the sealing performance between the sealing kit 1 and the pipe.

[0028] Among them, the miniature air pump 21 is fixedly installed inside the bottom frame 110, the two end fixing rings 23 are respectively fixedly installed at both ends of the inner wall of the fixed sleeve 11, and the airbag 24 is movably sleeved on the outer surface of the second rubber sleeve 18.

[0029] like Figure 2 As shown, a connecting pipe 17 is fixedly connected to one end of the top of the fixed sleeve 11. The outer surface of the connecting pipe 17 is provided with external threads. An mounting block 14 is fixedly installed on the top of the fixed sleeve 11. A second snap-fit ​​groove 16 is provided on the right end of the top of the mounting block 14. A first snap-fit ​​groove 15 is provided on both sides of the left end of the mounting block 14.

[0030] like Figure 5 As shown, the detection component 3 includes a gas detector 31. A fixing plate 32 is fixedly installed on the left end of the bottom of the gas detector 31. A fixing bolt 39 is installed on the internal thread of the fixing plate 32. An L-shaped clamp 33 is fixedly installed on the right end of the bottom of the gas detector 31. A wire 34 is fixedly connected to the right end of the gas detector 31. A fixing cover 35 is fixedly connected to one end of the wire 34. A detection probe 36 is fixedly connected to one end of the wire 34. The detection probe 36 is fixedly connected to the fixing cover 35. An audible and visual alarm 37 and a pressure gauge 38 are fixedly installed on the top of the gas detector 31.

[0031] The fixing cover 35 is threaded onto the outer surface of the connecting pipe 17, the L-shaped locking block 33 is snapped into the inside of the second locking groove 16, the fixing plate 32 is inserted into the inside of the first locking groove 15, and the fixing plate 32 is fixedly connected to the left side of the mounting block 14 by fixing bolts 39.

[0032] The working process of this utility model is as follows:

[0033] In use, the first rubber sleeve 12 and the second rubber sleeve 18 at both ends of the fixing sleeve 11 are respectively fitted onto the outer surfaces of the two pipes, so that the connection between the two pipes is located inside the fixing sleeve 11. By rotating the bolts on the outer surface of the pipe clamp 13, the first rubber sleeve 12 is pressed onto the outer surface of the pipe, completing the connection between the sealing kit 1 and the pipe. Then, the L-shaped locking block 33 at the bottom of the gas detector 31 is placed inside the second locking groove 16. The fixing plate 32 is located on the left side of the mounting block 14 and is inserted into the first locking groove 15. The fixing plate 32 is locked to the mounting block 14 by the fixing bolt 39, completing the installation of the detection component 3. Then, the detection probe 36 is inserted into the inside of the fixing sleeve 11 through the connecting pipe 17. By rotating the fixing cover 35, the fixing cover 35 is locked to the connecting pipe 17.

[0034] When a gas leak occurs between the two pipes, the detection probe 36 detects the gas and triggers the audible and visual alarm 37 via an electrical signal. At the same time, the micro air pump 21 is activated via an electrical signal, which delivers the gas through the connecting air pipe 22 into the airbag 24. At this time, the airbag 24 inflates and is squeezed against the outer surface of the second rubber sleeve 18, so that the second rubber sleeve 18 and the airbag 24 are squeezed against the outer surface of the pipe, creating a seal between them.
