Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas pipeline technology, and in particular to a gas pipe structure that facilitates quick sealing and connection. Background Technology
[0002] In today's society, natural gas, as an efficient and clean energy source, is widely used in industrial production and daily life. As a key carrier for gas transportation, the performance of the connection structure of gas pipelines directly affects the safety, stability, and construction efficiency of gas transportation.
[0003] Traditional gas pipe connections mostly use flange connections, requiring flanges to be installed at both ends of the gas pipe and tightened with multiple bolts and nuts. However, this process not only requires precise alignment of numerous bolt holes on the flange but also the individual tightening of nuts, making the operation complicated, time-consuming, and labor-intensive, resulting in low construction efficiency and increased labor costs. Secondly, traditional gas pipes use simple rubber ring seals or sealant fillings, but rubber rings are prone to aging and deformation over long-term use due to factors such as gas composition, temperature changes, and pipeline vibration, leading to decreased sealing performance and gas leaks. This not only wastes energy but also poses serious safety hazards. Utility Model Content

[0022] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0023] like Figure 1 As shown, this embodiment provides a gas pipe structure for easy and quick sealing and connection, including: a gas pipe 1 and a first connector 2 and a second connector 3 disposed at both ends of the gas pipe 1; the gas pipe 1 is made of polyethylene material, which has good flexibility, excellent corrosion resistance and high strength, enabling the gas pipe 1 to adapt to various installation environments; the first connector 2 is smaller than the diameter of the gas pipe 1 and can be threaded to the second connector 3. Threaded connection ensures connection strength while improving the efficiency of connecting the two gas pipes 1, saving significant installation time and labor costs compared to traditional flange connections; grooves 5 are formed on the outer walls of both ends of the gas pipe 1, and sealing sleeves 4 are fitted over the grooves 5. The sealing sleeves 4 are used to seal the connection between the first connector 2 and the second connector 3; Figure 5 As shown, the inner wall of the sealing sleeve 4 is symmetrically provided with sealing strips 401. The sealing strips 401 have a preset elasticity and are interference fit with the groove 5. The sealing strips 401 on the sealing sleeve 4 can effectively fill the tiny gaps at the connection and form a double sealing structure with the threaded connection of the first pair of connectors 2 and the second pair of connectors 3, preventing the risk of gas leakage from the connection, improving the reliability of the overall structure, and ensuring the safety of the gas transmission process.
[0024] like Figure 2-3As shown, the first connector 2 includes: a connecting pipe 201, one end of which is connected to one end of the gas pipe 1. The connecting pipe 201 and the gas pipe 1 are integrally formed, and an external thread 202 is provided on it. A groove 203 is formed on the working surface of the connecting pipe 201 near the gas pipe 1. The groove 203 is adapted to the working size of the limiting mechanism 303, which can provide precise alignment and fixation for the sealing connection of the two gas pipes 1.
[0025] like Figure 2-3 As shown, the second connector 3 includes: a sleeve 301, one end of which is connected to the other end of the gas pipe 1, and its inner wall is provided with an internal thread 302, which is threadedly connected to the external thread 202. During installation, the threaded connection of the first connector 2 and the second connector 3 enables the two gas pipes 1 to be quickly connected, saving docking time and improving installation efficiency. The sleeve 301 is provided with multiple limiting mechanisms 303 at the end away from the gas pipe 1. The limiting mechanisms 303 can engage with the groove 203. The limiting mechanisms 303 play a positioning and guiding role in the connection of the two gas pipes 1, making the docking of the first connector 2 and the second connector 3 more accurate and convenient. In addition, it can effectively prevent the threads from loosening due to factors such as vibration of the gas pipe 1 and external impact, enhance the stability of the connection between the two gas pipes 1, and ensure the safety and stability of the gas transmission process.
[0026] like Figure 3-4 As shown, the limiting mechanism 303 includes: a sealing bead 304, a connecting rod 309 connected to the sealing bead 304, and a guide cylinder 307 that penetrates one side of the sleeve 301. One end of the connecting rod 309 is connected to the sealing bead 304. The tight fit between the sealing bead 304 and the groove 203 can compensate for minor gaps during the connection process, reduce the risk of gas leakage, and thus enhance the sealing performance of the connection. The other end of the connecting rod 309 penetrates the guide cylinder 307 and is connected to a limiting plate 306. The limiting plate 306 is larger than the working size of the guide cylinder 307, and the guide cylinder 307 can provide precise guidance for the movement of the connecting rod 309. This allows it to move along a preset trajectory; the connecting rod 309 is equipped with an elastic ball 308, which is fitted with a return spring 305; the guide cylinder 307 has through holes on both sides, which can engage with the elastic ball 308; the elastic ball 308 moves with the connecting rod 309 within the guide cylinder 307, and when the elastic ball 308 moves to the through hole, it engages with the through hole, thereby positioning the connecting rod 309, at which point the connecting rod 309 will not move; when it is necessary to disassemble the first pair of connectors 2 and the second pair of connectors 3, the operator presses the elastic ball 308, and the elastic ball 308 is compressed and retracted into the guide cylinder 307, at which point the two gas pipes 1 can be separated.
[0027] In use, the operator screws the first connector 2 of one gas pipe 1 into the second connector 3 of the other gas pipe 1. At this time, the external thread 202 and the internal thread 302 are threaded together. When screwed to the preset position, the sealing bead 304 is inserted into the groove 203. At this time, the elastic ball 308 is also engaged with the through hole, thereby realizing the quick sealing connection of the two gas pipes 1. Then, the operator presses the sealing strip 401 on the sealing sleeve 4 into the groove 5 to achieve a double sealing structure.
[0028] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
