Description

Technical Field

[0001] The present application relates to the field of gas pipelines, and in particular to a wall-penetrating installation structure of an anti-corrosion gas pipeline. Background Art

[0002] A gas pipeline is a special pipeline for transporting combustible gas. In order to increase the service life of the gas pipeline, anti-corrosion measures are often taken on the gas pipeline, such as covering it with an anti-corrosion coating or using anti-corrosion materials to make the pipe body.

[0003] In the related art, when installing the gas pipeline, firstly, an installation hole is opened on the wall by an electric drill, and then one end of the gas pipeline is passed through the installation hole to be located indoors, and then the end of the gas pipeline located indoors is connected to the gas-using appliance, and the end of the gas pipeline located outdoors is connected to the gas supply part to achieve the installation of the gas pipeline. The gas pipeline has the characteristics of easy installation, connection, good flexibility, long service life, and can be arbitrarily and easily, and is widely used in municipal, household and other fields.

[0004] With respect to the above-mentioned related technologies, the inventors believe that after the gas pipeline passes through the installation hole on the wall, there will inevitably be a gap between the gas pipeline and the installation hole, resulting in poor indoor sealing, causing indoor air leakage and poor thermal insulation performance of the building. Summary of the invention

[0005] In order to improve the problem of poor indoor sealing caused by a gap between the gas pipeline and the installation hole, the present application provides a wall-penetrating installation structure for an anti-corrosion gas pipeline.

[0006] The present application provides an anti-corrosion gas pipeline through-wall installation structure adopts the following technical solution:

[0007] A wall-penetrating installation structure for an anti-corrosion gas pipeline, comprising an installation cylinder, a gas pipe and a drive assembly;

[0008] The installation tube is coaxially arranged in the installation hole of the wall, and the interior of the solid part of the installation tube is hollow to form an installation chamber, and a spray bottle is arranged in the installation chamber;

[0009] The spray bottle stores a foam plugging agent, and a liquid guide tube is also provided in the spray bottle. A pressing portion and a pressing nozzle connected to the liquid guide tube are provided on the spray bottle. When the pressing portion is squeezed, the foam plugging agent is sprayed out at the pressing nozzle. The pressing nozzle is connected to a liquid outlet pipe, and the liquid outlet pipe simultaneously penetrates the inner wall and the outer wall of the mounting tube to form a plurality of liquid outlet holes, and an atomizing nozzle is provided in the liquid outlet hole;

[0010] The channel in the installation cylinder is the installation channel, the gas pipe passes through the installation channel, and when the gas pipe passes through the installation channel, it cooperates with the driving component to press the pressing part.

[0011] By adopting the above technical solution, when installing the gas pipe, first set the installation cylinder in the installation hole of the wall, and then pass the gas pipe through the installation channel. When the gas pipe passes through the installation channel, it cooperates with the driving component to press the pressing part, and then the foam plugging agent passes through the pressing nozzle and the liquid outlet pipe in turn, and finally is atomized by the atomizing nozzle and sprayed out from the liquid outlet holes on the inner and outer walls of the installation cylinder.

[0012] After the foam plugging agent is sprayed out from the liquid outlet hole on the inner wall of the installation tube, it is located in the gap between the gas pipe and the inner wall of the installation tube; there will inevitably be a gap between the outer wall of the installation tube and the inner wall of the installation hole of the wall. After the foam plugging agent is sprayed out from the liquid outlet hole on the outer wall of the installation tube, it is located in the gap between the inner wall of the installation hole on the wall and the outer wall of the installation tube. The foam plugging agent expands after being sprayed out in atomization, and gradually solidifies after contacting water molecules in the air, thereby achieving double blocking of the gap between the gas pipe and the inner wall of the installation tube, and the gap between the inner wall of the installation hole on the wall and the outer wall of the installation tube, thereby fixing the gas pipe and blocking it in the installation hole on the wall, improving the indoor sealing, and improving the problems of indoor air leakage and poor thermal insulation performance of the building. At the same time, the gas pipe is fixed, integrating the fixation of the gas pipe with multiple blocking, simplifying the operation process, and improving the convenience of gas pipe installation.

[0013] Optionally, the pressing part includes a driving plate, a hydraulic cylinder body, a driving spring and a piston rod;

[0014] The interior of the solid part of the installation cylinder is also hollow to form a receiving chamber, the receiving chamber is located between the installation chamber and the installation channel, and the driving plate is rotatably arranged in the receiving chamber;

[0015] The hydraulic cylinder body is located between the liquid guiding tube and the pressing nozzle, and the hydraulic cylinder body is communicated with the liquid guiding tube and the pressing nozzle at the same time;

[0016] The driving spring is arranged in the hydraulic cylinder body, the piston rod passes through the side wall between the installation chamber and the accommodating chamber, the piston rod is slidably arranged in the hydraulic cylinder body, one end of the piston rod is connected to the driving spring, and the other end of the piston rod is connected to an end of the driving plate away from the driving plate rotating shaft;

[0017] The driving assembly includes a driving rod, and a slide groove for sliding the driving rod is provided on the inner wall of the installation channel, and the slide groove is communicated with the accommodating chamber, and one end of the driving rod abuts against a side of the driving plate away from the piston rod, and the other end of the driving rod is located in the installation channel and is provided with a first wedge surface and a second wedge surface, the first wedge surface faces the end of the installation tube through which the gas pipe penetrates, and the second wedge surface faces the end of the installation tube through which the gas pipe penetrates;

[0018] The gas pipe comprises a pipe body and hollow joints arranged at both ends of the pipe body. The diameter of the hollow joints is larger than the diameter of the pipe body and is matched with the aperture of the installation channel.

[0019] By adopting the above technical solution, the size of the installation tube can be set according to the installation requirements in actual conditions. In the process of passing the gas pipe from one end of the installation tube to the other end, when the end of the hollow joint away from the tube body abuts against the first wedge surface on the driving rod, as the gas pipe continues to pass through, the hollow joint causes the driving rod to slide in the direction close to the piston rod, thereby driving the piston rod to slide in the direction close to the driving spring. At this time, the driving spring contracts and the air in the hydraulic cylinder is discharged.

[0020] When the hollow joint moves to a point where it is out of contact with the drive rod, the drive spring stretches, thereby automatically driving the piston rod to slide in a direction away from the drive spring, thereby drawing the foam plugging agent into the hydraulic cylinder body;

[0021] At this time, the gas pipe is moved back, that is, moved in the direction of penetration of the installation tube, and the end of the hollow joint close to the pipe body is in contact with the second wedge surface, and the piston rod is driven by the driving rod to slide into the hydraulic cylinder body, thereby pushing out the foam plugging agent in the hydraulic cylinder body and entering the pressing nozzle and the liquid outlet pipe in turn, and finally sprayed out from the liquid outlet hole after being atomized by the atomizing nozzle. The staff can choose the number of times to repeat the reciprocating movement of the hollow joint according to the actual situation, so that the gap between the gas pipe and the inner wall of the installation tube, and the gap between the inner wall of the installation hole on the wall and the outer wall of the installation tube are filled with sufficient foam plugging agent to improve the plugging effect. Since it takes a certain amount of time for the foam plugging agent to solidify, the hollow joint can reciprocate normally.

[0022] When the hollow joint reaches the required number of reciprocating times, the gas pipe is passed out of the installation tube at a suitable length, and is left to stand for the foam plugging agent to be blocked and solidified. During the process of the gas pipe passing out of the installation tube, the driving rod is disengaged from the hollow joint, so that the driving rod has a tendency to reset. As the gas pipe moves, the end of the driving rod provided with the first wedge surface and the second wedge surface can scrape off part of the foam plugging agent adhered to the outer wall of the gas pipe, which helps to reduce the foam plugging agent on a section of the gas pipe outside the wall. A small amount of foam plugging agent on a section of the gas pipe outside the wall will not affect the normal use of the gas pipe.

[0023] The spray bottle and the pressing part are actually widely used liquid spray structures, which work in coordination with the gas pipe to achieve the purpose of integrating the fixation and multiple plugging of the gas pipe, simplifying the operation process, and improving the convenience of gas pipe installation.

[0025] By adopting the above technical solution, the dovetail groove can limit the width direction of the dovetail rod, and the limiting plate can limit the length direction of the dovetail rod, thereby improving the sliding stability of the dovetail rod in the dovetail groove, and further improving the sliding stability of the driving rod.

[0026] Optionally, the liquid conduit includes a liquid conduit main pipe and multiple rows of liquid conduit branches connected to the liquid conduit main pipe, the liquid conduit branches in the same row are arranged along the length direction of the liquid conduit main pipe, and multiple rows of liquid conduit branches are arranged along the circumference of the liquid conduit main pipe.

[0027] By adopting the above technical solution, the liquid guiding tube can absorb the foam plugging agent from multiple directions in the spray bottle, thereby improving the adequacy of the foam plugging agent absorbed into the liquid guiding tube.

[0028] Optionally, the liquid outlet pipe includes a liquid outlet main pipe and a plurality of liquid outlet branch pipes connected to the liquid outlet main pipe, the plurality of liquid outlet branch pipes are arranged along the length direction of the liquid outlet main pipe, the pressing portion and the pressing nozzle are both connected to the liquid outlet main pipe; the liquid outlet hole is formed by the liquid outlet branch pipes simultaneously penetrating the inner wall and the outer wall of the mounting tube.

[0029] By adopting the above technical solution, the foam sealant can be sprayed from different parts of the inner wall and the outer wall of the installation tube, thereby improving the dispersion and uniformity of the foam sealant filled in the gap between the gas pipe and the inner wall of the installation tube, and the gap between the inner wall of the installation hole on the wall and the outer wall of the installation tube, thereby improving the sealing effect.

[0030] Optionally, the end of the hollow joint away from the pipe body is threadedly connected to a connecting block, and a pull rod made of hard material is fixedly connected to the connecting block. The length of the pull rod is greater than the thickness of the wall. The end of the pull rod away from the connecting block is fixedly connected to a pull ring, and the pull ring can pass through the installation channel.

[0031] By adopting the above technical solution, when the gas pipe needs to pass through the installation tube, first pass the pull ring and the pull rod through the installation channel, then the staff will buckle the pull ring from the other side of the wall and pull it, and then pull the gas pipe into the installation channel; when the hollow joint is located at the driving rod, the pull rod can be quickly and repeatedly pulled and pushed back to achieve the hollow joint to make the driving rod reciprocate, and the gas pipe can be quickly pulled out from the outlet end of the installation tube, reducing the time for the gas pipe to pass through the installation channel, so that the gas pipe can pass through the installation tube before the foam plugging agent solidifies. When the gas pipe passes through the outlet end of the installation tube to a suitable length, unscrew the connection block from the hollow joint, and the gas pipe can be connected normally, which is simple and convenient to operate.

[0032] Optionally, there are multiple pressing parts on the spray bottle, and the multiple pressing parts are arranged along the length direction of the installation channel.

[0033] By adopting the above technical solution, multiple nozzles can be pressed to improve the reliability of foam blocking and sufficient spraying.

[0035] When the installation tube is not completely arranged in the installation hole of the wall, a conical drill bit is threadedly connected to one end of the installation tube away from the matching hole, and drill grooves are provided on the peripheral side walls of the installation tube and the conical drill bit.

[0036] By adopting the above technical solution, when it is necessary to install a gas pipe, the electric drill rod that matches the matching hole is inserted into the matching hole, and the conical drill bit is placed against the wall. The electric drill is started and the direction of rotation of the electric drill rod is controlled to be the direction in which the conical drill bit is tightened on the installation tube.

The installation tube 1 is coaxially arranged in an installation hole 31 of a wall 3, and the passage in the installation tube 1 is an installation passage 11. The gas pipe 2 passes through the installation passage 11 and is fixedly installed in the installation passage 11.

[0061] Reference Figure 1 and Figure 3The gas pipe 2 includes a pipe body 21 and a hollow joint 22 fixedly connected to both ends of the pipe body 21. The diameter of the hollow joint 22 is larger than the diameter of the pipe body 21, and the diameter of the hollow joint 22 is adapted to the aperture of the installation channel 11. A connecting block 23 is detachably mounted on the hollow joint 22 at one end. The connecting block 23 includes a first column 231 and a second column 232 coaxially arranged and fixedly connected. The diameter of the first column 231 is smaller than the diameter of the second column 232, and the diameter of the second column 232 is equal to the diameter of the hollow joint 22. The first column 231 is inserted into the hollow joint 22 at one end of the pipe body 21 and is threadedly connected to the inner wall of the hollow joint 22 at this end, so as to realize the detachable connection between the connecting block 23 and the hollow joint 22.

[0062] Reference Figure 1 and Figure 3 A pull rod 24 made of a hard material is fixedly connected to one side of the second column 232 away from the first column 231. In this embodiment, the pull rod 24 is a steel rod, and the length of the pull rod 24 is greater than the thickness of the wall 3. A pull ring 25 is fixedly connected to one end of the pull rod 24 away from the second column 232. The outer diameter of the pull ring 25 is smaller than the aperture of the installation channel 11, so that the pull ring 25 can pass through the installation channel 11. When the gas pipe 2 needs to pass through the installation tube 1, the pull ring 25 and the pull rod 24 are first passed through the installation channel 11, and then the staff buckles the pull ring 25 from the other side of the wall 3 and pulls it, and then pulls the gas pipe 2 into the installation channel 11.

[0063] Reference Figure 1 , Figure 4 and Figure 5 The insertion end of the installation tube 1 is provided with a matching hole 12 for use with an electric drill.

A friction pad 121 is fixedly connected to the inner wall of the matching hole 12.

[0064] When it is necessary to install the installation tube 1 in the installation hole 31, insert the drill rod of the electric drill that matches the matching hole 12 into the matching hole 12, and place the conical drill bit 13 against the wall, start the electric drill and control the direction of rotation of the drill rod of the electric drill to tighten the conical drill bit 13 on the installation tube 1.

As the drill rod of the electric drill is fed, the conical drill bit 13, the installation tube 1 and the drill groove 14 cooperate with each other to drill a hole on the wall 3 to form the installation hole 31. While drilling, the installation tube 1 is installed in the installation hole 31 on the wall 3, which is easy to operate. The setting of the drill groove 14 not only facilitates drilling, but also improves the firmness of the installation tube 1 installed in the installation hole 31 of the wall 3. After the installation tube 1 is installed, the conical drill bit 13 is unscrewed from the installation tube 1, and the gas pipe 2 can be inserted into the installation channel 11 to install the gas pipe 2. A friction pad 121 is fixedly connected to the inner wall of the matching hole 12 in order to increase the friction between the drill rod of the electric drill and the inner wall of the matching hole 12 to facilitate drilling.

The blocking cover 15 and the conical drill bit 13 cooperate with each other to block the two ends of the installation channel 11, so that it is not easy for debris to fall into the installation channel 11, which is convenient for the gas pipe 2 to penetrate. In addition, it is not easy for debris to accidentally touch the pressing part 5 and cause the foam plugging agent to spray out. After the installation tube 1 is set in the installation hole 31 on the wall 3, the blocking cover 15 is rotated by the handle to remove the blocking cover 15 from the installation channel 11, and the gas pipe 2 is normally penetrated.

The liquid outlet hole 44 is formed by the liquid outlet branch 432 penetrating the inner wall and the outer wall of the mounting tube 1 at the same time. The liquid outlet pipe 43 penetrates the inner wall and the outer wall of the mounting tube 1 at the same time to form a plurality of liquid outlet holes 44, and an atomizing nozzle is fixedly connected in the liquid outlet hole 44. The pressing portion 5 is pressed, and then the foam plugging agent passes through the pressing nozzle 42 and the liquid outlet pipe 43 in turn, and finally is atomized by the atomizing nozzle and sprayed out from the liquid outlet holes 44 on the inner wall and the outer wall of the mounting tube 1. By setting the liquid outlet branch pipe 432, the foam sealant can be sprayed from different parts of the inner wall and the outer wall of the installation tube 1, thereby improving the dispersion and uniformity of the foam sealant filled in the gap between the gas pipe 2 and the inner wall of the installation tube 1, and the gap between the inner wall of the installation hole 31 on the wall 3 and the outer wall of the installation tube 1, thereby improving the sealing effect.

[0069] After the foam plugging agent is sprayed out from the liquid outlet 44 on the inner wall of the installation tube 1, it is located in the gap between the gas pipe 2 and the inner wall of the installation tube 1; after the foam plugging agent is sprayed out from the liquid outlet 44 on the outer wall of the installation tube 1, it is located in the gap between the inner wall of the installation hole 31 on the wall 3 and the outer wall of the installation tube 1. The foam plugging agent expands after being sprayed out in atomization, and gradually solidifies after contacting water molecules in the air, thereby achieving double blocking of the gap between the gas pipe 2 and the inner wall of the installation tube 1, and the gap between the inner wall of the installation hole 31 on the wall 3 and the outer wall of the installation tube 1, thereby improving the indoor sealing performance and improving the problems of indoor air leakage and poor thermal insulation performance of the building. At the same time, the gas pipe 2 is fixed, and the fixing of the gas pipe 2 and multiple blocking are integrated, which improves the convenience of installing the gas pipe 2.

[0070] Reference Figure 2 , Figure 7 and Figure 8The interior of the solid part of the installation tube 1 is also hollow and has four accommodating chambers 18, of which two accommodating chambers 18 are located between the installation channel 11 and the installation chamber 17 on the left, and the other two accommodating chambers 18 are located between the installation channel 11 and the installation chamber 17 on the right. The two pressing parts 5 on the same spray bottle 4 are arranged side by side along the length direction of the installation tube 1, and each pressing part 5 corresponds to one accommodating chamber 18. The pressing part 5 includes a driving plate 51, a hydraulic cylinder body 52, a driving spring 53 and a piston rod 54. The driving plate 51 is rotatably connected to the accommodating chamber 18, one end of the hydraulic cylinder body 52 is located in the spray bottle 4 and between the liquid guide tube 41 and the pressing nozzle 42, the other end of the hydraulic cylinder body 52 penetrates the spray bottle 4 and is located outside the spray bottle 4, and the end of the hydraulic cylinder body 52 located outside the spray bottle 4 penetrates the side wall between the accommodating chamber 18 and the corresponding installation chamber 17. The hydraulic cylinder body 52 is communicated with the liquid guiding tube 41 and the pressing nozzle 42 at the same time, and the length direction of the hydraulic cylinder body 52 is parallel to the width direction of the spray bottle 4 .

[0071] Reference Figure 8 , the driving spring 53 is fixedly installed in the hydraulic cylinder body 52, and the driving spring 53 is coaxially arranged with the hydraulic cylinder body 52. ​​The piston rod 54 penetrates the side wall between the installation chamber 17 and the accommodating chamber 18, and the piston rod 54 is slidably installed in the hydraulic cylinder body 52. ​​The piston rod 54 includes a first rod body 541 and a second rod body 542 that are hinged to each other. The first rod body 541 is located in the hydraulic cylinder body 52, and the end of the first rod body 541 away from the second rod body 542 is a sealing part 543 made of rubber. The sealing part 543 is fixedly connected to the end of the driving spring 53 away from the liquid guiding main pipe 411, and the diameter of the sealing part 543 is adapted to the aperture of the hydraulic cylinder body 52; the end of the second rod body 542 away from the first rod body 541 is hinged to the side of the driving plate 51 away from the installation channel 11.

[0072] Reference Figure 7 and Figure 8 A driving assembly 6 is installed on the mounting tube 1. The driving assembly 6 includes a driving rod 61 and a dovetail rod 62. A sliding groove 111 for the driving rod 61 to slide is opened on the inner wall of the mounting channel 11. The sliding groove 111 is communicated with the accommodating chamber 18. One end of the driving rod 61 abuts against a side of the driving plate 51 away from the piston rod 54. The other end of the driving rod 61 is located in the mounting channel 11 and is provided with a first wedge surface 611 and a second wedge surface 612. The first wedge surface 611 faces the end of the mounting tube 1 where the gas pipe 2 penetrates, and the second wedge surface 612 faces the end of the mounting tube 1 where the gas pipe 2 penetrates.

[0073] In the process of passing the gas pipe 2 from one end of the installation tube 1 to the other end, the pull ring 25 and the pull rod 24 are first passed through the installation channel 11, and then the staff holds the pull ring 25 from the other side of the wall 3 and pulls it, and then pulls the gas pipe 2 into the installation channel 11. When the end of the hollow joint 22 away from the tube body 21 abuts against the first wedge surface 611 on the driving rod 61, as the pull rod 24 continues to pull, the hollow joint 22 causes the driving rod 61 to slide toward the direction close to the piston rod 54, thereby driving the piston rod 54 to slide toward the direction close to the driving spring 53. At this time, the driving spring 53 contracts and the air in the hydraulic cylinder body 52 is discharged;

[0074] When the hollow joint 22 moves to a position where it is no longer in contact with the driving rod 61, the driving spring 53 is extended, thereby automatically driving the piston rod 54 to slide in a direction away from the driving spring 53, thereby drawing the foam plugging agent into the hydraulic cylinder body 52;

[0075] At this time, push the pull rod 24 back to move the hollow joint 22 back, that is, move it in the direction of insertion of the installation tube 1, and the end of the hollow joint 22 close to the tube body 21 abuts against the second wedge surface 612, and drives the piston rod 54 to slide into the hydraulic cylinder body 52 through the driving rod 61, thereby pushing out the foam plugging agent in the hydraulic cylinder body 52 and entering the pressing nozzle 42 in turn.

[0076] The staff can choose the number of times to repeat the reciprocating movement of the hollow joint 22 according to the actual situation, so that the gap between the gas pipe 2 and the inner wall of the installation tube 1, and the gap between the inner wall of the installation hole 31 on the wall 3 and the outer wall of the installation tube 1 are filled with sufficient foam plugging agent to improve the plugging effect. Through the pull rod 24 and the pull ring 25, the pull rod 24 can be quickly and repeatedly pulled and pushed back to achieve the hollow joint 22 to make the drive rod 61 slide back and forth, and the gas pipe 2 can be quickly pulled out from the outlet end of the installation tube 1, reducing the time for the gas pipe 2 to pass through the installation channel 11, so that the gas pipe 2 passes through the installation tube 1 before the foam plugging agent solidifies. After the gas pipe 2 passes through the outlet end of the installation tube 1 for a suitable length, unscrew the connecting block 23 from the hollow joint 22, and wait for the foam plugging agent to be blocked and solidified. In addition, the normal connection of the gas pipe 2 is simple and convenient to operate.

[0077] Reference Figure 8 and Fig. 9 The dovetail rod 62 is fixedly connected to the side surface of one side of the driving rod 61, and a dovetail groove 112 for the dovetail rod 62 to slide is provided on the inner wall of the slide groove 111. The dovetail groove 112 can limit the width direction of the dovetail rod 62, thereby improving the sliding stability of the dovetail rod 62 in the dovetail groove 112; both ends of the dovetail rod 62 are fixedly connected with a limiting plate 621, and the cross-sectional area of ​​the limiting plate 621 is larger than the size of the opening of the dovetail groove 112. The limiting plate 621 can limit the length direction of the dovetail rod 62, thereby improving the sliding stability of the driving rod 61.

[0078] The implementation principle of the wall-penetrating installation structure of an anti-corrosion gas pipeline in the embodiment of the present application is as follows:

[0079] When the installation tube 1 needs to be installed in the installation hole 31, the drill rod of the electric drill matched with the matching hole 12 is inserted into the matching hole 12, and the conical drill bit 13 is pressed against the wall surface to drill a hole and realize that the installation tube 1 is located in the installation hole 31 of the wall 3. After the installation tube 1 is installed, the conical drill bit 13 and the blocking cover 15 are unscrewed from the installation tube 1.

[0080] Pass the pull ring 25 and the pull rod 24 through the installation channel 11, and then the staff holds the pull ring 25 from the other side of the wall 3 and pulls it, and then pulls the gas pipe 2 into the installation channel 11, and quickly and repeatedly pulls and pushes the pull rod 24 back and forth to realize the hollow joint 22 to make the driving rod 61 slide back and forth, and fully spray the foam plugging agent; after reaching the specified number of reciprocating times, quickly pull the gas pipe 2 out of the outlet end of the installation tube 1, so that the gas pipe 2 passes through the outlet end of the installation tube 1 to a suitable length, unscrew the connecting block 23 from the hollow joint 22, and let it stand and wait for the foam plugging agent to seal and solidify.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
