[0003] The welds of existing gas pipelines are often not easy to seal for emergency protection, so when a gas leak occurs at the weld of the gas pipeline, the gas is likely to continue to leak, causing safety hazards. Utility Model Content
[0004] The purpose of the utility model is to provide a gas pipeline leakage emergency protection structure for solving the problem that the welding parts of the existing gas pipelines are often not convenient for emergency sealing protection.
[0005] In order to solve the above problems, the utility model provides a gas pipeline leakage emergency protection structure, comprising two gas pipelines welded together, wherein the two gas pipelines are respectively provided with a fixing ring, and an annular groove is respectively provided on the opposite sides of the two fixing rings, and a sealing sleeve is respectively provided on the two gas pipelines, and one side of the sealing sleeve is inserted into the corresponding annular groove so that the sealing sleeve is arranged in a stepped shape, and a conical ring is provided at the step of the sealing sleeve, and a jacking pipe is provided between the two conical rings, and the two ends of the jacking pipe respectively conflict with the conical surface of the corresponding conical ring.
[0006] The gas pipeline leakage emergency protection structure provided by the utility model also has the following technical features:
[0007] Furthermore, a plurality of mounting plates arranged in a ring array are fixed to opposite sides of the two fixing rings, and the two corresponding mounting plates on the two fixing rings are connected by a bolt.
[0008] Furthermore, a positioning tube is fixed on the outside of the top tube, and both ends of the positioning tube are respectively inserted into the corresponding annular grooves.
[0009] Furthermore, both ends of the top pipe are provided with conical surfaces matching with corresponding conical rings.
[0010] Furthermore, combustible gas detectors are fixedly installed on the jacking pipe and the positioning pipe.
[0011] Furthermore, an annular seat is fixedly connected to the positioning tube, a transparent cover is threadedly connected to the annular seat, and the combustible gas detector is located inside the transparent cover.
[0012] The utility model has the following beneficial effects: by making the two fixing rings move relative to each other, the two ends of the top pipe respectively come into contact with the conical surfaces of the corresponding conical rings, and the conical rings apply force to the step of the sealing sleeve, so that the sealing sleeve plays a sealing role, so that when gas leakage occurs at the weld of the gas pipeline, the leaked gas is sealed in the space between the top pipe and the gas pipeline, thereby avoiding continuous leakage of gas and causing safety hazards, and thus playing a role of emergency protection.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.
[0017] like Figures 1 to 3 In the embodiment of the gas pipeline leakage emergency protection structure of the present invention shown, the gas pipeline leakage emergency protection structure includes two gas pipelines 1 welded together, and a fixing ring 2 is respectively provided on the two gas pipelines 1, and an annular groove 3 is respectively opened on the opposite sides of the two fixing rings 2, and a sealing sleeve 4 is respectively provided on the two gas pipelines 1, and one side of the sealing sleeve 4 is inserted into the corresponding annular groove 3, so that the sealing sleeve 4 is arranged in a stepped shape, and a conical ring 5 is provided at the step of the sealing sleeve 4, and a top pipe 6 is provided between the two conical rings 5, and the two ends of the top pipe 6 respectively conflict with the conical surface of the corresponding conical ring 5. By making the two fixing rings 2 move relative to each other, the two ends of the top pipe 6 respectively conflict with the conical surface of the corresponding conical ring 5, and the conical ring 5 applies force to the step of the sealing sleeve 4, thereby playing a sealing role through the sealing sleeve 4, so that when gas leakage occurs at the weld of the gas pipeline, the leaked gas is sealed in the space between the top pipe 6 and the gas pipeline 1, thereby avoiding continuous leakage of gas and causing safety hazards, thereby playing a role of emergency protection.
[0018] In one embodiment of the present application, preferably, a plurality of mounting plates 7 arranged in a ring array are fixed on the opposite sides of the two fixing rings 2, and the two corresponding mounting plates 7 on the two fixing rings 2 are connected by a bolt. By using the bolt to connect the two corresponding mounting plates 7, the position between the two fixing rings 2 can be relatively fixed, and the conical ring 5 can be squeezed toward the sealing sleeve 4.
[0019] In one embodiment of the present application, preferably, a positioning tube 8 is fixed on the outside of the top tube 6, and both ends of the positioning tube 8 are respectively inserted into the corresponding annular groove 3. The positioning tube 8 serves to limit the top tube 6, and the positioning tube 8 is slidably connected to the annular groove 3.
[0020] In one embodiment of the present application, preferably, both ends of the top pipe 6 are provided with conical surfaces that match the corresponding conical rings 5, so that the two ends of the top pipe 6 are in close contact with the corresponding conical rings 5 to play a sealing role, and a sealing ring can be provided between the top pipe 6 and the corresponding conical ring 5 to play a further sealing role.
[0021] In one embodiment of the present application, preferably, a combustible gas detector 9 is fixedly installed on the top pipe 6 and the positioning pipe 8, and the combustible gas detector 9 is used to detect the gas concentration in the space between the top pipe 6 and the gas pipeline 1, and then an alarm is issued when a gas leak occurs, thereby facilitating rapid processing by the staff.
[0022] In one embodiment of the present application, preferably, an annular seat 10 is fixedly connected to the positioning tube 8, a transparent cover 11 is threadedly connected to the annular seat 10, and the combustible gas detector 9 is located inside the transparent cover 11, and the transparent cover 11 can protect the combustible gas detector 9.
[0023] When the utility model is in use, the two fixing rings 2 are moved relative to each other, and the corresponding two mounting plates 7 are connected by using bolts, so that the position between the two fixing rings 2 can be relatively fixed, and the conical ring 5 can be squeezed toward the sealing sleeve 4, and the positioning tube 8 plays a role in limiting the top pipe 6. The positioning tube 8 is slidably connected to the annular groove 3, and the two ends of the top pipe 6 are in close contact with the corresponding conical ring 5, and the conical ring 5 applies force to the step of the sealing sleeve 4, so as to play a sealing role through the sealing sleeve 4. When gas leakage occurs at the weld of the gas pipeline, the leaked gas is blocked in the space between the top pipe 6 and the gas pipeline 1, thereby avoiding continuous leakage of gas and causing safety hazards, and thus playing a role of emergency protection. The combustible gas detector 9 detects the gas concentration in the space between the top pipe 6 and the gas pipeline 1, and then alarms when gas leaks, which is convenient for staff to handle quickly.
