[0019] In order to more clearly understand the above -mentioned purpose, feature and advantage of the utility model, the utility model is further explained below with the help of drawings and examples. It is to be explained that the embodiment of the application and the feature in the embodiment can be combined mutually in the case of not conflicting.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a through-wall pipe assembly with a lockable sleeve, including a wall 1, an external wall insulation layer 2 on the outside of the wall 1, a sleeve body 3 between the inner surface of the wall 1 and the external wall insulation layer 2, two first threads 4 on the outer surface of the sleeve body 3, two locking caps 5 movably fitted on the outer surface of the sleeve body 3, two first sealants 7 between the outer surface of the sleeve body 3 and the inner surface of the wall 1 and the external wall insulation layer 2, an air supply pipe 8 on the inner surface of the sleeve body 3, two second sealants 9 between the outer surface of the air supply pipe 8 and the inner surface of the sleeve body 3, one side of the outer wall of each of the two locking caps 5 is in contact with one side of the outer wall of the wall 1 and the external wall insulation layer 2, and the inner surface of each of the two locking caps 5 is threadedly connected to the outer surface of the first threads 4.

[0022] The overall effect of Embodiment 1 is as follows: When the gas supply pipe 8 needs to be installed, firstly, under the operation of the staff, a through hole of appropriate size is opened on the outer wall of the wall 1 and the outer wall insulation layer 2. Since the inner wall of the locking cover 5 is threaded, the locking cover 5 can be installed on the outer wall of the sleeve body 3 by means of threaded connection. The locking cover 5 is fixed by threading through the end of the shorter first thread 4 on the outer wall of the sleeve body 3. The first sealant 7 is applied at the connection between the locking cover 5 and the sleeve body 3 and at the joint between the locking cover 5 and the outer wall surface. After being squeezed, the first sealant 7 reaches between the sleeve body 3 and the through hole to improve the sealing performance. Then, under the operation of the staff, the other end of the sleeve body 3 is inserted into the room through the through hole, and the position of the sleeve body 3 in the through hole is adjusted. The centerline of the sleeve body 3 is aligned with the centerline of the outdoor elbow interface. Then, under the operator's guidance, the locking cap 5 is threaded onto one end of the indoor sleeve body 3 using the first thread 4. The first sealant 7 is then applied using the same method, completing the installation and fixation of the sleeve body 3. Next, the factory-made anti-corrosion gas supply pipe 8 is inserted into the sleeve body 3 and connected to the elbow of the outdoor branch pipe. The gap between the inner wall of the sleeve body 3 and the outer wall of the gas supply pipe 8 is filled with a weather-resistant flexible second sealant 9, improving the stability of the gas supply pipe 8 and the seal between it and the sleeve body 3. This method completes the installation, fixation, and sealing of the through-wall gas supply pipe 8, greatly improving the practicality of the installation components and extending the service life of the pipeline.

[0023] Example 2: As Figures 2-4As shown, the outer wall of the gas supply pipe 8 is provided with two second threads 10, and the outer wall of the gas supply pipe 8 is provided with a corrosion-resistant layer 11.

[0024] The effect achieved by the whole embodiment 2 is that the gas supply pipe 8 is subjected to degreasing and shot blasting treatment on the outer surface under the operation of the staff after the completion of the molding, and the corrosion-resistant layer 11 made of cross-linked polyethylene is further processed on the surface, so that the gas supply pipe 8 has good corrosion resistance during use, prolongs the service life, and the second threads 10 are processed on the outer wall of the gas supply pipe 8 at both ends, facilitating the connection with other branch pipes.

[0025] Working principle: before the installation of the through-wall gas supply pipe 8, the gas supply pipe 8 with good corrosion resistance is first manufactured in the factory, and the second threads 10 are provided at both ends, and when the gas supply pipe 8 is installed, a through hole of appropriate size is formed on the outer wall of the wall body 1 and the outer wall of the external wall thermal insulation layer 2 under the operation of the staff, then the locking cap 5 is installed on the outer wall of the sleeve body 3 in a threaded connection manner, so that the locking cap 5 is fixed by thread connection through one end of the shorter first thread 4 formed on the outer wall of the sleeve body 3, and the first sealant 7 is applied at the connection between the locking cap 5 and the sleeve body 3 and the joint between the locking cap 5 and the outer wall surface, and the first sealant 7 reaches the sleeve body 3 and the through-wall hole after extrusion to improve the sealing performance, then the other end of the sleeve body 3 is inserted into the indoor through the through-wall hole under the operation of the staff, and the position of the sleeve body 3 in the through-wall hole is adjusted so that the center line of the sleeve body 3 coincides with the center line of the outdoor elbow interface, thereby fixing the one end of the locking cap 5, and then the first thread 4 is used to install the locking cap 5 on the one end of the indoor sleeve body 3 under the operation of the staff, and the first sealant 7 is applied in the same way as described above, thereby completing the installation and fixation of the sleeve body 3, then the corrosion-resistant gas supply pipe 8 manufactured in the factory is inserted into the sleeve body 3 and connected with the elbow of the outdoor branch pipe, and the gap between the inner wall of the sleeve body 3 and the outer wall of the gas supply pipe 8 is filled with the flexible second sealant 9 with good weather resistance, thereby improving the stability of the gas supply pipe 8 and the sealing performance between the sleeve body 3 and the gas supply pipe 8, and the installation, fixation and sealing of the through-wall gas supply pipe 8 can be completed by the method.
