There are many types of gas, mainly natural gas, artificial coal gas, liquefied petroleum gas, biogas, and coal-to-gas. It has good environmental performance and is affordable, but gas transportation requires pipelines.

[0003] The existing public patent (publication number CN 219954560 U) discloses a gas pipeline, which relates to the technical field of gas pipelines, including a gas pipeline body, on which a plurality of protective components are movably provided, which protect the gas pipeline body when an external force hits the gas pipeline body, and a joint component is provided at one end of the gas pipeline body, which is used to seal the opposite ends of multiple gas pipeline bodies, and the protective component includes two arc-shaped fixing plates, and two fixing cylinders are fixed on the side of the two arc-shaped fixing plates away from the gas pipeline body. The utility model is connected to the outside of the gas pipeline body by two arc-shaped fixing plates, and the external force hits the protective plate to squeeze the spring, which plays a buffering role. At the same time, two arc-shaped pipes are connected to the two ends of the gas pipeline body to realize the joint, and the arc-shaped sealing gasket and the sealing strip are sealed to avoid the gas pipeline body from being hit and leaking, thereby improving the safety of the use of the utility model.

[0004] However, when the gas pipeline is in use, if the gas pipeline needs to be constructed, the gas delivery in the pipeline needs to be stopped to ensure the safety of the gas pipeline construction, resulting in the gas supply to users being affected. Therefore, the utility model proposes a sealing structure for safe construction of gas pipelines to improve the above problem. Utility Model Content

[0005] The utility model aims to provide a sealing structure for safe construction of a gas pipeline, so as to solve the problem that the existing gas pipeline is inconvenient to use during construction as mentioned in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealing structure for safe construction of a gas pipeline, comprising a sealing assembly and a pipeline assembly connected to the sealing assembly; the sealing assembly comprises a sealing pipe, a sealing valve arranged at the end of the sealing pipe, a pressure measuring pipe connected to the sealing valve, and a pressure measuring valve arranged at the horizontal branch of the pressure measuring pipe; the pipeline assembly comprises a gas branch pipe connected to the sealing valve, a transfer pipe connected to the arc-shaped end of the gas branch pipe, a control valve arranged on the periphery of the gas branch pipe, and a gas main pipe fixed to the end of the transfer pipe.

[0007] Preferably, a fixing piece is fixed to the bottom of the sealing tube, and the fixing piece is fixed to the outer contact surface via bolts.

[0008] Preferably, two sealing assemblies are provided, and the sealing tubes in the two sealing assemblies are arranged in parallel.

[0009] Preferably, the gas delivery branch pipes in a single pipeline assembly are arranged in parallel, and the gas delivery branch pipes are connected to the sealing pipe via a sealing valve.

[0010] Preferably, the gas main pipe is communicated with an external gas pipeline, and the gas main pipe is symmetrically arranged at the air inlet and the air outlet of the sealing component.

[0011] Preferably, the pressure measuring tube is communicated with the interior of the sealing valve, and the pressure measuring tube and the sealing valve are arranged in a one-to-one correspondence.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a sealing component to connect the gas pipeline to the diversion, cooperates with the gas delivery of the pipeline component, and conveniently cuts off the corresponding pipeline gas during the gas pipeline construction without affecting the normal gas delivery of other pipelines, thereby ensuring the safety of the gas pipeline construction and convenient operation;

[0014] Specifically, the pipeline assembly and the sealing assembly are connected to the gas pipeline as a whole. Under normal circumstances, the gas in the gas pipeline enters the transfer pipe through the gas main pipe, and then enters the gas branch pipe through the transfer pipe, and enters the sealing assembly through the gas branch pipe. The pressure measuring valve monitors the pipeline pressure in the sealing assembly in real time. The gas is transported through the sealing assembly and enters the gas pipeline again through the pipeline assembly at the exhaust for normal transportation of the gas. During the construction of the gas pipeline, it is necessary to cut off the gas transported by the corresponding pipeline. Here, it is necessary to cut off the corresponding pipeline branch in the sealing assembly, close the sealing valve at the corresponding pipeline branch, block the transported gas, and set a pressure measuring valve to detect the pressure of the pipeline to avoid gas leakage. The sealing pipe with the sealing valve not closed continues to transport the gas. The above-mentioned sealing blocking method is used to ensure the safety of gas construction.

Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-4 , in the figure: This embodiment is a preferred implementation of the technical solution, a sealing structure for safe construction of a gas pipeline, comprising a sealing assembly 2 and a pipeline assembly 1 connected to the sealing assembly 2; the sealing assembly 2 comprises a sealing pipe 21, a sealing valve 22 arranged at the end of the sealing pipe 21, a pressure measuring pipe 24 connected to the sealing valve 22, and a pressure measuring valve 25 arranged at the horizontal branch of the pressure measuring pipe 24; the pipeline assembly 1 comprises a gas branch pipe 12 connected to the sealing valve 22, a transfer pipe 11 connected to the arc-shaped end of the gas branch pipe 12, a control valve 13 arranged on the peripheral side of the gas branch pipe 12, and a gas main pipe 14 fixed to the end of the transfer pipe 11;

[0023] It should be noted that: in the sealing structure for safe construction of gas pipelines involved in the present application, the gas pipeline is connected by arranging the sealing component 2 to cooperate with the gas transportation of the pipeline component 1, so that the corresponding pipeline gas can be cut off during the construction of the gas pipeline without affecting the normal gas transportation of other pipelines, thereby ensuring the safety of the gas pipeline construction and convenient operation. Specifically, the pipeline component 1 and the sealing component 2 are connected to the gas pipeline as a whole. Under normal circumstances, the gas in the gas pipeline enters the transfer pipe 11 through the gas main pipe 14, and then enters the gas branch pipe 12 from the transfer pipe 11, and enters the sealing component 2 through the gas branch pipe 12. The pressure measuring valve 25 monitors the pipeline pressure in the sealing component 2 in real time. The gas is transported through the sealing component 2 and re-enters the gas pipeline from the pipeline component 1 at the exhaust for normal transportation of the gas. During the construction of the gas pipeline, it is necessary to cut off the gas transported by the corresponding pipeline. Here, it is necessary to cut off the corresponding pipeline branch in the sealing component 2, close the sealing valve 22 at the corresponding pipeline branch, block the transported gas, and set the pressure measuring valve 25 to detect the pressure of the pipeline to avoid gas leakage. The sealing pipe 21 that has not closed the sealing valve 22 continues to transport the gas. The above-mentioned sealing and blocking method is used to ensure the safety of gas construction.

[0024] Among them Figure 1 and Figure 2 As shown, a fixing member 23 is fixed to the bottom of the sealing tube 21, and the fixing member 23 is fixed to the outer contact surface by bolts; two sealing assemblies 2 are provided, and the sealing tubes 21 in the two sealing assemblies 2 are arranged in parallel; the gas branch pipes 12 in a single pipeline assembly 1 are arranged in parallel, and the gas branch pipes 12 are connected to the sealing tubes 21 through the sealing valve 22;

[0025] It should be noted that the fixing part 23 is used to fix the position of the sealing tube 21. After the fixing part 23 is fixed to the external contact surface by bolts, the overall position of the sealing assembly 2 is fixed. Two sealing assemblies 2 are provided for switching between the sealing assemblies 2 during gas construction. The gas branch pipe 12 corresponds to the sealing assembly 2 and is used for transporting gas in and out of the sealing assembly 2.

[0026] Among them Figure 3 As shown, the gas delivery pipe 14 is connected to the external gas pipeline, and the gas delivery pipe 14 is symmetrically arranged at the gas inlet and the gas outlet of the sealing component 2;

[0027] It should be noted that the gas transmission main pipe 14 is in communication with an external gas pipeline to ensure the normal transmission function of the entire gas pipeline. Meanwhile, the gas transmission main pipe 14 is used for gas to enter and exit the interior of the sealing component 2 .

[0028] Among them Figure 4As shown, the pressure measuring tube 24 is connected to the inside of the sealing valve 22, and the pressure measuring tube 24 and the sealing valve 22 are arranged in a one-to-one correspondence;

[0029] It should be noted that after the pressure measuring tube 24 is connected to the inside of the sealing valve 22 , the pressure inside the pressure measuring tube 24 and the sealing valve 22 are the same, which facilitates the pressure measuring valve 25 to accurately measure the internal pressure of the sealing valve 22 through the pressure measuring tube 24 .
