Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, and particularly relates to a gas pipeline wall-piercing encapsulation device. Background Art

[0002] When a gas pipeline enters a room from the outside, it needs to pass through a wall hole into the room. In order to avoid damage to the pipe body at this place, it is necessary to encapsulate and protect the gas pipeline inside the wall and keep the pipeline fixed.

[0003] The patent with the publication number CN206973072U provides a wall-piercing installation structure for a gas pipeline, which includes a gas pipe with threads at both ends. The gas pipe passes through the wall and exposes the threads at both ends. A sleeve is sleeved on the gas pipe. End caps are provided at both ends of the sleeve. Concrete is poured outside the sleeve to integrate the sleeve, the gas pipe and the wall. A filling port is provided on the end cap. Waterproof and flame-retardant filler is poured into the sleeve through the filling port onto the outer surface of the gas pipeline; however, the installation structure of the above patent has the following problems: Direct irrigation of the flame-retardant filler will cause complete solidification and bonding between the pipeline and the sleeve or the wall hole, which is not conducive to the subsequent replacement of this section of the gas pipeline, resulting in extremely troublesome demolition of the gas pipeline during later maintenance.

[0004] In summary, it is considered to design a device that can encapsulate and fix the gas pipeline to avoid the problem of inconvenient disassembly caused by bonding of the gas pipeline, so as to facilitate subsequent maintenance and disassembly operations; in view of this, we propose a gas pipeline wall-piercing encapsulation device. Content of the Utility Model

[0010] Two end cap units, including an outer end cap and a sealing rubber ring installed at both ends of the outer sleeve. A grouting hole is provided on the outer end cap, and the grouting hole is used to fill a sealing material into the gap between the wall installation hole and the outer sleeve.

[0011] Preferably, the outer sleeve includes a first half pipe and a second half pipe that are detachably installed;

[0012] The first half pipe is provided with a threaded port, and the second half pipe is provided with a threaded protrusion for threaded installation in the threaded port.

Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the above technical solutions of the present utility model will be described in detail through the following embodiments:

[0030] A gas pipeline wall-piercing encapsulation device for encapsulating and fixing the gas pipeline 4, as Figure 1 shown in the installation sectional view of this embodiment, includes:

[0031] The outer sleeve 1 is used to be installed in the wall installation hole. In this embodiment, the outer sleeve 1 is provided with a through hole 101. In order to facilitate the disassembly and assembly of the outer sleeve 1, as in Figure 3 , Figure 4 shown in the structure, the outer sleeve 1 includes a first half pipe 11 and a second half pipe 12 that are detachably installed. The first half pipe 11 is provided with a threaded port 111, and the second half pipe 12 is provided with a threaded protrusion 121 for threaded installation in the threaded port 111.

[0032] The rubber inner lining pipe 3 is used to fit on the outer wall of the gas pipeline 4; it should be noted that, in order to facilitate the fixing of the rubber inner lining pipe 3, as in Figure 1 and Figure 6 shown in the structure, the first half pipe 11 and the second half pipe 12 are provided with slots for inserting the rubber inner lining pipe 3, so that the rubber inner lining pipe 3 can be fixed at the inner wall of the outer sleeve 1 after the first half pipe 11 and the second half pipe 12 are closed and installed.

[0033] Two end cap units 2, as in Figure 5 and Figure 6The structure shown includes outer end caps 21 and sealing rubber rings 22 installed at both ends of the outer sleeve 1. A grouting hole 211 is provided on the outer end cap 21. The grouting hole 211 is used to fill the gap between the wall installation hole and the outer sleeve 1 with a sealing material. In this embodiment, the sealing material is the 008-type flame-retardant expanding sealant sold by Langfang Shuangze Environmental Protection Technology Co., Ltd.; in order to facilitate installation in the wall hole in this embodiment, the two outer end caps 21 are respectively threadedly installed on the outer ends of the first half pipe 11 and the second half pipe 12.

[0034] It should be noted that at the corresponding positions of the outer end cap 21 and the outer sleeve 1, there is a counter groove 2101 as shown Figure 6 in the figure. The sealing rubber ring 22 is detachably installed in the counter groove 2101; the contact surface between the sealing rubber ring 22 and the counter groove 2101 is of a slope structure. The outer end cap 21 is used to squeeze the sealing rubber ring 22 to fit on the outer wall of the gas pipeline 4. After the gas pipeline 4 to be installed is inserted into the wall hole and before the gas pipeline 4 is encapsulated, the end cap unit 2 is sleeved on both ends of the gas pipeline 4, and the port is sealed by spirally squeezing the sealing rubber ring 22.

[0035] The working principle of the gas pipeline wall-piercing encapsulation device in this embodiment is as follows: First, place the sealing rubber ring 22 on the inner walls of the first half pipe 11 and the second half pipe 12, and insert the gas pipeline 4 to be installed, so that the inner sealing rubber ring 22 will not collapse and deform during the installation process. Subsequently, the first half pipe 11 and the second half pipe 12 are inserted into the wall hole from both sides, and the closure is completed by threaded rotation. Finally, as shown Figure 1 in the figure, install the end cap unit 2 at both ends; then inject the 008-type flame-retardant expanding sealant sold by Langfang Shuangze Environmental Protection Technology Co., Ltd. through the grouting hole 211. After curing, the colloid expands and squeezes the sealing rubber ring 22 to deform through the through hole 101, so that the sealing rubber ring 22 fits on the gas pipeline 4 to maintain the encapsulation stability. The surface of the gas pipeline 4 is not bonded, which is convenient for disassembly and assembly during subsequent maintenance and replacement of the gas pipeline 4.
