Description

Technical Field

[0001] This utility model is a socket-type stainless steel pipe fitting, belonging to the field of stainless steel pipe fitting connection technology. Background Technology

[0002] Some stainless steel pipe fittings are generally installed using either welded sockets or snap-fit ​​sockets. Welding is not convenient for disassembly and assembly, while snap-fit ​​sockets usually use rubber rings. Specifically, a rubber ring smaller than the inner diameter of the pipe is placed into the inner wall of one of the pipes, and then another pipe with a smaller outer diameter is inserted into the pipe containing the rubber ring. The smaller outer diameter pipe passes through the rubber ring while squeezing the rubber ring, thereby achieving a socket sealing connection. However, this type of socket-type pipe fitting also has the following shortcomings: the rubber ring has a small amount of compression deformation, which can easily lead to unreliable sealing and leakage. This is because in order to ensure smooth insertion, the gap between the two socket pipes is usually increased. If the gap between the two socket pipes is further reduced, the smaller outer diameter pipe can easily shear the rubber ring during insertion, affecting the sealing connection. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a socket-type stainless steel pipe fitting.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A socket-type stainless steel pipe fitting includes a socket-connecting pipe fitting. Two stainless steel pipe fittings, Stainless Steel Fitting 1 and Stainless Steel Fitting 2, are respectively provided at both ends of the socket-connecting pipe fitting. The two ends of the socket-connecting pipe fitting are symmetrically provided with arc-shaped socket grooves. Threaded knobs penetrating the arc-shaped socket grooves are threaded onto the outer walls of both ends of the socket-connecting pipe fitting. Both Stainless Steel Fitting 1 and Stainless Steel Fitting 2 are integrally connected to a socket sealing assembly at one end of the socket-connecting pipe fitting. Arc-shaped inserts matching the arc-shaped socket grooves are provided on both Stainless Steel Fitting 1 and Stainless Steel Fitting 2 outside the socket sealing assembly.

[0005] Furthermore, the socket connection fitting includes a socket connection pipe, with an inner sealing coupling cylinder integrally connected to both ends of the socket connection pipe. A socket sealing cavity is formed between the inner sealing coupling cylinder and the socket connection pipe. A rubber gasket is provided on the outer wall of the inner sealing coupling cylinder, and a sealing groove is provided on the outer wall of the socket sealing cavity. An inner groove is provided on the inner wall of the socket connection pipe.

[0008] Furthermore, the arc-shaped plug includes an arc-shaped metal sheet integrally connected to one end of stainless steel pipe fitting 1 and stainless steel pipe fitting 2. The center of the arc-shaped metal sheet is provided with a threaded hole that matches the threaded knob. A damping pad is attached to the inner wall of the arc-shaped metal sheet, and the damping pad is provided with an inclined surface.

The inner wall of the stainless steel pipe fitting body at the end away from the socket connection pipe fitting is provided with an internal thread for connection, and the inner wall of the stainless steel pipe fitting body is sprayed with an anti-rust coating.

[0010] The beneficial effects of this utility model are: By setting stainless steel fitting one and stainless steel fitting two at both ends of the socket-connected pipe fitting, and through the action of the socket sealing assembly, stainless steel fitting one and stainless steel fitting two are sealed to the socket-connected pipe fitting. After that, the arc-shaped insert is inserted into the arc-shaped socket groove, and then connected by the threaded knob. This ensures the stability of the socket-connected pipe fitting after being connected to stainless steel fitting one and stainless steel fitting two. This utility model has a simple structure, is easy to use, and can effectively improve the sealing effect of stainless steel fitting one and stainless steel fitting two to the socket-connected pipe fitting, making it less prone to water leakage problems, and has high stability after connection.
