Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, and more specifically, to a gas through-wall pipe device. Background Technology

[0002] Gas is a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly including natural gas, manufactured gas, liquefied petroleum gas, biogas, and coal gas. Gas pipelines are special pipelines used to transport combustible gases. Common gas pipelines include natural gas pipelines.

[0003] Gas pipelines passing through walls are usually protected by wall penetration devices. However, existing gas wall penetration devices have poor sealing and waterproofing performance, which allows foreign objects and rainwater to easily enter the metal sleeve, increasing the risk of corrosion damage to the metal sleeve and affecting the reliability of the gas wall penetration device. Based on this, this utility model designs a gas wall penetration device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a gas-powered wall-penetrating pipe device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gas-powered through-wall pipe device includes a gas transmission pipe, a decorative front cover, a metal sleeve, a decorative rear cover, and a threaded collar. Both ends of the gas transmission pipe are provided with threaded connectors I. An anti-corrosion layer is fixedly sleeved on the outer side of the gas transmission pipe. A sealing waterproof ring is provided between the metal sleeve and the anti-corrosion layer. A positioning waterproof ring is sleeved on the outer side of the anti-corrosion layer. A threaded connector II is provided at the rear end of the metal sleeve. A mounting screw groove I is opened on the inner side of the front end of the threaded collar. The threaded connector II is threadedly connected to the mounting screw groove I. The positioning waterproof ring abuts against the threaded connector II and the threaded collar. The decorative front cover is sleeved on the outer side of the front end of the metal sleeve, and the decorative rear cover is sleeved on the outer side of the rear end of the metal sleeve. The threaded collar is located inside the decorative rear cover.

[0007] As a preferred technical solution of this utility model, the device also includes two protective covers, the inner side of which is provided with a mounting screw groove II, and the threaded joint part I is threadedly connected to the mounting screw groove II.

[0008] As a preferred embodiment of this utility model, the gas transmission pipe and the threaded joint I are integrally formed, and the metal sleeve and the threaded joint II are integrally formed.

[0009] As a preferred technical solution of this utility model, the anti-corrosion layer is a 3PE anti-corrosion material layer.

[0010] As a preferred embodiment of this utility model, both the sealing waterproof ring and the positioning waterproof ring are components made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention improves the overall sealing and waterproofing performance by setting a sealing and waterproofing ring between the metal sleeve and the anti-corrosion layer, with a positioning waterproofing ring fitted on the outer side of the anti-corrosion layer, a threaded joint II at the rear end of the metal sleeve, and a mounting screw groove I on the inner side of the front end of the threaded collar. The threaded joint II is threadedly connected to the mounting screw groove I, and the positioning waterproofing ring abuts against the threaded joint II and the threaded collar. This effectively prevents foreign objects and rainwater from entering the metal sleeve, reduces the risk of corrosion damage to the metal sleeve, and ensures the reliability of the gas through-wall pipe device.

[0013] This utility model provides threaded connectors I at both ends of the gas transmission pipe, allowing the two ends of the gas transmission pipe to be directly connected to the gas pipe for gas delivery. The inner side of the protective cover has a mounting screw groove II, and the threaded connector I is threadedly connected to the mounting screw groove II. By screwing the protective cover, it is easy to install and remove the threaded connector I on the gas transmission pipe. The protective cover can be used to seal and protect the two ends of the gas transmission pipe, preventing external impurities from easily entering the gas transmission pipe.
