Description

Technical Field

[0001] This utility model relates to the field of oil valve technology, specifically to an oil valve connection structure that is easy to assemble and disassemble. Background Technology

[0002] Oil valve connection structures mainly include three types: flange connections, threaded connections, and welded connections. Flange connections are suitable for valves of various nominal sizes and pressures, achieving a detachable connection through a combination of flanges, gaskets, and bolts. Threaded connections are typically used for pipelines ≤DN50 and are also detachable, but attention must be paid to sealing issues. Welded connections involve directly welding the valve body to the pipeline and are suitable for applications requiring a permanent connection. However, current oil valve connection structures still have the following shortcomings: For example, patent document CN220980422U discloses an easy-to-disassemble oil valve connection structure. This easy-to-disassemble oil valve connection structure can greatly reduce the labor intensity of manual labor and further improve the overall reliability and stability of the device to achieve a more practical purpose. However, it only uses flange bolt connection, which is time-consuming and inconvenient to disassemble and assemble, and is prone to leakage due to vibration and loosening, resulting in low maintenance efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a convenient oil valve connection structure, comprising an oil valve body and a sealing assembly. The oil valve body is an integral structure, and the sealing assembly is disposed on the surface of the oil valve body. The sealing assembly includes an annular threaded groove, a sealing gasket, an elastic sealing gasket, a sealing connecting ring, a connecting body, and a threaded mounting ring. The annular threaded groove is formed on both sides of the oil valve body, and a sealing gasket is disposed on both sides of the oil valve body. The inner surface of the sealing gasket is tightly connected to the two sides of the oil valve body. An elastic sealing gasket is disposed at both ends of the inner surface of the oil valve body, and a sealing connecting ring is engaged at both ends of the inner surface of the oil valve body. The sealing connecting ring is an integral structure and is made of stainless steel.

[0005] Furthermore, a connecting body is installed on the outer end surface of the sealing connecting ring, and the connecting body and the sealing connecting ring are an integrated structure that is tightly connected.

[0006] Furthermore, a threaded mounting ring is installed on the inner end surface of the connecting body, and the threaded mounting ring is threadedly connected to the inner surface of the annular threaded groove.

[0007] Furthermore, the surface of the oil valve body is provided with a fixing component for stable connection, and the fixing component includes a snap-fit ​​reinforcement groove, a snap-fit ​​reinforcement part, an outer protective ring, a reinforcement bolt, and an anti-loosening nut.

[0008] Furthermore, the snap-fit ​​reinforcement groove is formed on the outer surfaces of both ends of the oil valve body and the outer surfaces of both ends of the connecting body, and a snap-fit ​​reinforcement component is snapped into the inner side of the snap-fit ​​reinforcement groove.

[0009] Furthermore, an outer protective ring is installed on the outer surface of the snap-fit ​​reinforcement, and reinforcing bolts are threaded to both ends of the outer protective ring. An anti-loosening nut is threaded to the lower end of the reinforcing bolt.

[0010] Furthermore, the fixing assembly also includes a fixing bolt and a limiting nut, and the surface of the oil valve body is threadedly connected to the surface of the connecting body with the fixing bolt, and the surface of the fixing bolt is threadedly connected to the limiting nut.

This utility model, through the setting of a sealing component, includes an annular threaded groove, a sealing gasket, an elastic sealing gasket, a sealing connecting ring, a connecting body, and a threaded mounting ring. In use, the sealing connecting ring engages with the inside of the oil valve body, achieving a quick connection between the oil valve body and the connecting body. The elastic sealing gasket provides a dynamic seal when the valve is opened and closed, adapting to the movement of the valve plate and maintaining sealing performance. At the same time, the threaded mounting ring is threadedly connected to the annular threaded groove, and rotation enables quick fastening or separation of the valve body from the pipeline. The sealing gasket ensures a static seal between the valve body and the connecting components, preventing media leakage. Thus, this device, through its threaded connection and elastic sealing design, significantly improves the convenience of installation and disassembly and enhances sealing reliability.

[0013] 2. This utility model, by setting a fixing component, includes a snap-fit ​​reinforcement groove, a snap-fit ​​reinforcement member, an outer protective ring, a reinforcement bolt, and an anti-loosening nut.
