Description

Cassette union valve

Technical field:

The utility model relates to the technical field of valves, in particular to a card type live joint valve.

Background technique:

At present, the connection between the valve and the pipeline is generally a threaded connection. When installing and disassembling, the entire valve or pipeline needs to be rotated. The operation is very troublesome and the installation speed is slow. Therefore, people think of connecting the valve and the pipeline by means of switching. For example, the union valve disclosed in Chinese Patent No. CN2539888 has internal threads on both sides of the valve, and one end of the joint that realizes the transfer function is provided with external threads to connect with the valve, and the other end of the joint is fastened with a union cap. The union cap is connected with the pipeline through the internal thread provided on the inner wall. The union valve can be easily installed or disassembled by simply twisting the union cap. But both sides of this kind of union valve, the two ends of joint all will be provided with screw thread, processing trouble, high production cost, and the connection of joint and valve, pipeline all is threaded connection, and installation and dismounting are still more troublesome.

Utility model content:

The purpose of the utility model is to provide a snap-type union valve which is convenient for installation and disassembly in view of the deficiencies in the prior art.

In order to achieve the above purpose, the technical solution adopted by the utility model is: it includes a valve body, a handle, a connecting pipe located on the side of the valve body, and a nut sleeved on the outside of the connecting pipe. The end of the connecting pipe is provided with an annular groove. A snap ring is provided.

The snap ring is composed of two semicircular snap rings.

The nut and the connecting pipe are movable sockets.

A protruding edge for fastening the snap spring protrudes from one end of the nut socketed with the connecting pipe.

The beneficial effect of the utility model is that the utility model includes a valve body, a handle, a connecting pipe located at the side of the valve body and a nut socketed on the outside of the connecting pipe; , compared with the traditional valve, the union valve of this structure does not need to open multiple threads, the structure is simple, and the processing is easy; due to the movable socket structure of the nut, one end of the nut is engaged with the circlip, and the other end The threaded connection with the pipeline makes the installation and disassembly of the valve and the pipeline convenient, improves work efficiency and reduces production costs.

Description of drawings:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the structural representation of the utility model valve body and connecting pipe;

Fig. 3 is the structural representation of the utility model clasp;

Fig. 4 is a schematic diagram of the structure of the utility model connected with the pipeline.

Detailed ways:

The utility model will be further described below in conjunction with the accompanying drawings, as shown in accompanying drawings 1 to 4, the utility model includes a valve body 1, a handle 2 located on the valve body 1, a connecting pipe 3 and a sleeve located at the side of the valve body 1 The nut 4 connected to the outside of the connecting pipe 3, the nut 4 is movably sleeved on the connecting pipe 3, the end of the connecting pipe 3 is provided with an annular groove 5, and a retaining ring is arranged in the annular groove 5, and the retaining spring is composed of two semicircular The clasp 6 is composed of one end of the socket of the nut 4 and the connecting pipe 3 protruding from a protruding edge 7 for fastening the clasp, and the other end of the nut 4 is provided with an internal thread. When the utility model is connected to the pipeline, the nut 4 is sleeved on the connecting pipe 3 of the valve body 1, and the nut 4 is pushed to the other end of the connecting pipe 3 to expose the annular groove 5, and then the two semicircular clamps The ring 6 is stuck in the annular groove 5, and the sealing ring 8 is placed between the end face of the connecting pipe 3 and the end face of the pipe. When the pipeline is tightened, the connection between the valve and the pipeline is completed; when the connection between the utility model and the pipeline is disassembled, as long as the nut 4 is unscrewed, the pipeline can be taken off, and the operation is convenient and fast.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
