Description

Technical Field

[0001] This utility model relates to the field of natural gas high-pressure gas rail sealing technology, and in particular to a leak-proof natural gas high-pressure gas rail with an added sealing ring. Background Technology

[0002] In the transportation and application of natural gas, the high-pressure gas rail is a key component, and its sealing performance directly affects the efficiency and safety of natural gas transportation. Since the high-pressure gas rail is composed of multiple connected pipes, and only a ring-shaped sealing gasket is used to improve the sealing between the pipes, the high-pressure gas rail is prone to sealing failure at the pipe connection points due to factors such as pressure fluctuations, temperature changes, and mechanical vibrations during long-term use. This can lead to natural gas leakage, posing a significant threat to the lives and property of people in the surrounding area. Summary of the Invention

[0003] In order to solve the problems in the background art, this utility model proposes a leak-proof high-pressure gas rail for natural gas with added sealing ring.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A leak-proof high-pressure gas rail for natural gas with a sealing ring includes a gas pipe, one end of which is fixedly connected to a connecting sleeve, and the other end is provided with a connector that mates with the connecting sleeve.

[0006] Annular rubber ring: The connecting sleeve is provided with an annular rubber ring. Multiple annular protrusions are evenly provided on one side of the annular rubber ring, and multiple annular protrusions are evenly provided on the other side.

[0007] Preferably, the inner wall of the connecting sleeve is evenly provided with a plurality of annular sealing grooves II that cooperate with the annular protrusion II, and the end face of the connector is evenly provided with a plurality of annular sealing grooves I that cooperate with the annular protrusion I.

[0008] Preferably, the cross-sections of the first annular protrusion and the first annular sealing groove are both arc-shaped, and the cross-sections of the second annular protrusion and the second annular sealing groove are both trapezoidal.

[0009] Preferably, both the second annular protrusion and the first annular protrusion are made of flexible rubber.

[0010] Preferably, the outer wall of the connector is provided with an external thread, and the inner wall of the connector sleeve is provided with an internal thread that mates with the external thread.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] This invention utilizes an annular rubber ring to improve the sealing between the connecting sleeve and the connector, thereby preventing leakage at the connection of the high-pressure natural gas rail. Specifically, the use of the second annular protrusion increases the contact area between the annular rubber ring and the connecting sleeve, further enhancing their sealing performance. Similarly, the use of the first annular protrusion increases the contact area between the annular rubber ring and the connector, also improving their sealing performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution:

[0022] A leak-proof high-pressure gas rail for natural gas with added sealing rings includes a gas pipe 1. One end of the gas pipe 1 is fixedly connected to a connecting sleeve 2, and the other end is provided with a connector 3 that mates with the connecting sleeve 2. The connecting sleeve 2 and the connector 3 are fixedly connected to the gas pipe 1 by welding, which makes the connection between the connecting sleeve 2 and the connector 3 and the gas pipe 1 more stable and less prone to gas leakage, which is beneficial to gas transportation.

[0023] The connecting sleeve 2 is equipped with an annular rubber ring 5. Multiple annular protrusions 7 are evenly distributed on one side of the annular rubber ring 5, and multiple annular protrusions 6 are evenly distributed on the other side. The use of the annular rubber ring 5 improves the sealing performance between the connecting sleeve 2 and the connecting head 3, achieving the purpose of preventing leakage at the connection of the high-pressure natural gas rail. Specifically, the use of the annular protrusions 7 increases the contact area between the annular rubber ring 5 and the connecting sleeve 2, thereby improving the sealing performance between them. Similarly, the use of the annular protrusions 6 increases the contact area between the annular rubber ring 5 and the connecting head 3, thereby improving the sealing performance between them. The combined use of the annular protrusions 6 and 7 enhances the sealing performance between the connecting head 3 and the connecting sleeve 2, thus improving the sealing performance of the connection of the high-pressure natural gas rail.

[0024] In this invention, multiple annular sealing grooves 9 that mate with annular protrusions 7 are evenly provided on the inner wall of the connecting sleeve 2, and multiple annular sealing grooves 8 that mate with annular protrusions 6 are evenly provided on the end face of the connector 3. The cross-sections of annular protrusions 6 and annular sealing grooves 8 are arc-shaped, and the cross-sections of annular protrusions 7 and annular sealing grooves 9 are trapezoidal. This increases the contact area between the annular rubber ring 5 and the connecting sleeve 2 and the connector 3, thereby improving the sealing performance between the connector 3 and the connecting sleeve 2.

[0025] In this invention, both the second annular protrusion 7 and the first annular protrusion 6 are made of flexible rubber. By utilizing the flexibility of the flexible rubber material, the second annular protrusion 7 and the first annular protrusion 6 can be tightly fitted with the first annular sealing groove 8 and the second annular sealing groove 9 respectively, thereby improving the sealing performance between the connecting sleeve 2 and the connecting head 3.

[0026] In this utility model, the outer wall of the connector 3 is provided with an external thread 4, and the inner wall of the connector sleeve 2 is provided with an internal thread that mates with the external thread 4. The mutual use of the external thread 4 and the internal thread facilitates the splicing between the connector sleeve 2 and the connector 3, thereby facilitating the assembly of the high-pressure air rail and improving the efficiency of the high-pressure air rail installation.

[0027] Working principle: When installing a high-pressure natural gas rail, this utility model first fixes one of the gas pipes 1 in a suitable position, then places an annular rubber ring 5 inside the connecting sleeve 2, and the second annular protrusion 7 falls into the second annular sealing groove 9. Then, the connector 3 of the other gas pipe 1 is threaded into the already installed connecting sleeve 2. By squeezing the annular rubber ring 5, the first annular protrusion 6 and the second annular protrusion 7 fill the entire first annular sealing groove 8 and the second annular sealing groove 9 respectively. Following the above sequence, the gas pipes 1 are connected together to realize the installation of the high-pressure natural gas rail.

[0028] The use of the annular rubber ring 5 improves the sealing between the connector 3 and the connecting sleeve 2, preventing natural gas leakage. The cooperation between the annular protrusion 2 7 and the annular protrusion 1 6 increases the contact area between the annular rubber ring 5 and the connecting sleeve 2 and the connector 3, making the sealing between the connector 3 and the connecting sleeve 2 more stable.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
