Description

Technical Field

[0001] The utility model relates to the technical field of gas supply equipment, in particular to urban gas supply and transportation equipment. Background Art

[0002] Gas equipment and pipe networks are important facilities to ensure reliable gas supply in cities. They transport combustible media, and are distributed widely with many distribution points, covering the gas use of thousands of households. Gas equipment and pipe networks are distributed in various locations in the city with a wide coverage. Gas equipment mixes liquefied gas (natural gas) and air (or multiple gas sources) in a certain proportion to achieve the gas calorific value required by users, which can meet the requirements of different users such as civil and industrial users;

[0003] After inquiry, the publication (announcement) number: CN217301616U discloses an urban gas supply equipment. This technology discloses "including a joint, the joint has an inlet end and two coaxially symmetrically arranged conical outlet ends. The inlet end of the joint is connected to a gas supply pipe, and the two conical outlet ends of the joint are respectively connected to the inlet ends of a common conduit and a standby conduit. The outlet ends of the common conduit and the standby conduit are both connected to a delivery pipe, etc. technical solutions, which have a common conduit and a standby conduit. Under normal circumstances, the left plug abuts against the inner wall of the left conical outlet end, and the gas is transported through the common conduit and the delivery pipe; when the common conduit leaks, the plug can be driven to move to the right by a driving device cooperating with a rack, so that the right plug abuts against the inner wall of the right conical outlet end of the joint. At this time, the common conduit becomes ineffective, and the gas is transported through the standby conduit and the delivery pipe, ensuring that residents can use gas normally, etc. technical effects";

[0004] When the above design is in use, although the gas is transported through the standby conduit and the delivery pipe to ensure that residents can use gas normally, the installation of this plugging structure is relatively cumbersome, and after long-term use, the plug is prone to wear, resulting in poor sealing effect. At the same time, the structure occupies the internal space of the pipeline, affecting the transportation of gas and reducing the use effect of the device. Therefore, we propose an urban gas supply and transportation equipment to solve the above existing problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an urban gas supply and transportation equipment, which solves the problems that the plug is prone to wear and cause poor sealing effect, and at the same time the structure occupies the internal space of the pipeline, affecting the transportation of gas.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: An urban gas supply and transportation device, including a transportation pipe, a pipe one and a pipe two that are respectively connected and fixed to the surface of the transportation pipe. A gas supply pipe is fixed between the pipe one and the pipe two. Both the pipe one and the pipe two are connected and communicated with the transportation pipe. Plugging components are installed inside both the pipe one and the pipe two. The plugging component includes threaded pipes respectively arranged on the pipe one and the pipe two, a leather pipe fixed to one end of the threaded pipe, and an airbag ball fixed to the other end of the leather pipe. A control valve is installed inside the threaded pipe.

[0007] Preferably, both the pipe one and the pipe two are fixedly installed with threaded sleeves through the opened installation holes, and the threaded sleeves are in threaded connection with the threaded pipes.

[0008] Preferably, a tapered sleeve is fixed to the other end of the threaded pipe.

[0009] Preferably, a rubber end one is fixed to the bottom end of the inner cavity of the airbag ball. A rubber end two is arranged at the open end of the threaded pipe close to the leather pipe. A spring wire is fixedly installed between the rubber end two and the rubber end one.

[0010] Preferably, a rotating rod is fixed to the open end of the threaded pipe, and the surface of the rubber end two is sleeved and rotated on the surface of the rotating rod through the opened through hole.

[0011] Preferably, the elasticity of the leather pipe is lower than that of the airbag ball.

[0012] Beneficial effects

[0013] The utility model provides an urban gas supply and transportation device. Compared with the prior art, it has the following beneficial effects:

[0014] For this urban gas supply and transportation device, through the plugging component, the airbag ball is plugged and installed, so the installation efficiency is faster. After the airbag ball is inflated, it can closely fit the inner wall of the pipe to form a continuous sealing surface, which can effectively prevent gas leakage and will not cause leakage problems due to uneven sealing surfaces caused by wear or manufacturing precision problems. When the plugging of the pipe is removed, the airbag ball can be in a flat shape, which will not occupy a large amount of space inside the pipe and does not affect the transportation of gas, further improving the use effect of the device and meeting the actual use requirements.

[0021] As Figure 1 shown:

[0022] The urban gas supply and transportation equipment includes a delivery pipe 1 and a pipe one 2 and a pipe two 3 respectively connected and fixed to the surface of the delivery pipe 1. An air supply pipe 31 is fixed between the pipe one 2 and the pipe two 3, and both the pipe one 2 and the pipe two 3 are connected to the delivery pipe 1.

[0023] In this implementation plan: The existing device {publication (announcement) number}: CN217301616U discloses an urban gas supply equipment. Regarding this existing main body, the present application makes further improvements. For details, refer to the public technology below; To solve the technical problems existing in this existing technology, as disclosed in the background technology above, "when the above design is used, although the gas is transported from the standby conduit through the air supply pipe to ensure that residents can use gas normally, the sealing structure is relatively cumbersome. After long-term use, the plug is prone to wear and cause poor sealing effect. At the same time, the structure occupies the internal space of the pipeline, affecting the transportation of gas and reducing the use effect of the device". In combination with the use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a sealing assembly 4 is added to this application document.

[0024] As Figures 1-4 shown:

[0025] A plugging component 4 is installed inside both the first pipeline 2 and the second pipeline 3. The plugging component 4 includes threaded pipes 401 respectively arranged on the first pipeline 2 and the second pipeline 3, a leather tube 403 fixed to one end of the threaded pipe 401, and an airbag ball 404 fixed to the other end of the leather tube 403. A control valve 405 is installed inside the threaded pipe 401. Both the first pipeline 2 and the second pipeline 3 are fixedly installed with threaded sleeves 402 through the opened installation holes, and the threaded sleeves 402 are threadedly connected to the threaded pipes 401.

[0026] Specifically, a conical sleeve 406 is fixed to the other end of the threaded pipe 401. Through the setting of the conical sleeve 406, the air supply joint of the air pump can be better inserted onto the threaded pipe 401, improving the insertion effect and providing the air supply efficiency.

[0027] Furthermore, a first rubber end 407 is fixed to the bottom end of the inner cavity of the airbag ball 404. A second rubber end 409 is arranged at the open end of the threaded pipe 401 close to the leather tube 403. A spring wire 408 is fixedly installed between the second rubber end 409 and the first rubber end 407. Since the first rubber end 407, the spring wire 408, and the second rubber end 409 are arranged inside the airbag ball 404, a rod body is formed inside. Compared with the relatively soft state of the leather of the airbag ball 404, it is more convenient to insert the airbag ball 404 into the first pipeline 2 and the second pipeline 3 to complete the placement, improving the installation efficiency.

[0028] Furthermore, a rotating rod 410 is fixed to the open end of the threaded pipe 401. The surface of the second rubber end 409 is sleeved and rotated on the surface of the rotating rod 410 through the opened through hole. The second rubber end 409 rotates on the rotating rod 410. When the airbag ball 404 and the leather tube 403 are inside the pipeline, due to the gravity of the spring wire 408, the spring wire 408 drives the second rubber end 409 to rotate on the rotating rod 410, facilitating the downward angular folding of the airbag ball 404, and then driving the leather tube 403 to bend, making the placement position of the airbag ball 404 more accurate.

[0029] Furthermore, the elasticity of the leather tube 403 is lower than that of the airbag ball 404. When the leather tube 403 is inflated, the airbag ball 404 will expand while the leather tube 403 will not expand.

[0030] When installing the plugging component 4, at this time, the airbag ball 404 is sequentially placed inside the first pipeline 2 and the second pipeline 3 through the installation holes, and the leather tube 403 is also placed inside. Subsequently, the threaded pipe 401 is rotated, and the threaded pipe 401 is screwed into the threaded sleeve 402 to fix this mechanism to the pipeline.

[0031] When plugging, an external air pump (not shown in the figure) is used to connect the air supply end to the tapered sleeve 406 on the threaded pipe 401. Subsequently, air is supplied through the air pump, and the gas passes through the threaded pipe 401 and the leather tube 403 and is discharged into the interior of the airbag ball 404, causing the airbag ball 404 to continuously expand to plug the pipeline 2 or the pipeline 3. Subsequently, the control valve 405 is closed to prevent gas from escaping.

[0032] In summary, through the plugging and installation of the airbag ball 404, the installation efficiency is faster. After the airbag ball 404 is inflated, it can closely fit the inner wall of the pipeline, forming a continuous sealing surface, which can effectively prevent gas leakage and will not cause leakage problems due to uneven sealing surfaces caused by wear or manufacturing precision problems. When removing the plug from the pipeline, the airbag ball 404 can be flat, will not occupy a large amount of space inside the pipeline, and will not affect the transportation of gas, further improving the use effect of the device and meeting the actual use requirements.

[0033] It should be noted that: in this air supply method, in the absence of an air pump, it can be blown manually, and the control valve 405 can be flexibly adjusted to open and close during this process.

[0034] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
