Description

Technical Field

[0001] This application relates to the field of fluid piping fittings, and more particularly to a hose fitting for fluid piping. Background Technology

[0002] In fluid pipelines, most connections are made using metal fittings and rubber hoses. However, as is well known, conventional rubber hoses harden in cold environments, significantly reducing their sealing performance with metal fittings and ultimately leading to leaks at the connection. To address this issue, the industry typically focuses on continuously developing and improving the material of rubber hoses to ensure they maintain a proper seal with metal fittings even in cold environments.

[0003] However, the inventor believes that while improving the material of the rubber hose can improve the sealing performance, it also significantly increases the production and usage costs of the rubber hose fittings. Utility Model Content

[0004] In order to improve the sealing performance between the joint and the pipe in cold environments, and to significantly reduce manufacturing and usage costs when the sealing performance is good.

[0005] This application provides a flexible hose connector for fluid pipelines, employing the following technical solution:

[0006] A hose connector for fluid pipelines includes a tubular body, one end of which is provided with a connecting pipe end, and the connecting pipe end is provided with at least one main sealing assembly, the main sealing assembly including one or at least two spaced annular sealing grooves.

[0007] In some embodiments, a secondary sealing group is provided on at least one side of one of the main sealing groups at the end of the connector, and the secondary sealing group includes one or at least two annular grooves with triangular cross sections spaced apart.

[0008] In some embodiments, the secondary sealing assembly is disposed on the side of the connector end away from the main body.

[0009] In some embodiments, the outer radial direction of the end of the connector farthest from the body gradually decreases.

[0010] In some embodiments, a first annular retaining ring is provided on the side of the connector end near the main body, and an annular retaining groove is formed between the first retaining ring and the main body.

[0011] In some embodiments, a second retaining ring is provided at the end of the main body near the end of the connector, and the outer diameter of the second retaining ring is larger than the outer diameter of the first retaining ring.

[0012] In summary, this application includes at least one of the following beneficial technical effects: by improving the connector of the pipe end, designing an annular sealing groove directly on the pipe end, and utilizing the cooperation of the sealing groove and the sealing ring, the sealing performance between the connector and the pipe in cold environments can be improved, and with good sealing performance, manufacturing and usage costs can be significantly reduced.

[0015] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0016] This application discloses a hose connector for fluid pipelines, referring to... Figure 1 The system includes a tubular main body 1, with a connecting pipe end 2 at one end. The connecting pipe end 2 has at least one main sealing assembly, which contains one or at least two spaced annular sealing grooves 3. The number and shape of the main sealing assemblies are not restricted and can be set according to the actual needs of the scenario. After adopting the annular sealing grooves 3, it can be used in conjunction with a sealing ring. The sealing ring can be made of a material that can guarantee performance in cold environments. The rubber fittings connected to the hose connector can use the original traditional materials. This controls manufacturing costs, reduces usage costs, and greatly improves the sealing performance at the connection.

[0017] Additionally, a secondary sealing group can be provided on at least one side of one of the main sealing groups on the connector end 2. The secondary sealing group contains one or at least two annular grooves 4 with triangular cross sections spaced apart. The secondary sealing group is designed to further improve the sealing performance. Generally, the secondary sealing group is located on the side of the connector end 2 away from the main body 1. The outer radial direction of the end of the connector end 2 away from the main body 1 gradually decreases. This design can provide a certain degree of guidance for the installation of the rubber hose and make the installation more convenient and quick.

[0018] In this embodiment, a first annular retaining ring 5 is provided on the side of the connector end 2 near the main body 1, and an annular retaining groove 7 is formed between the first retaining ring 5 and the main body 1; a second retaining ring 6 is provided on the end of the main body 1 near the connector end 2, and the outer diameter of the second retaining ring 6 is larger than the outer diameter of the first retaining ring 5. The design of the first retaining ring 5 and the second retaining ring 6 can limit the installation of the rubber tube.

[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
