Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a socket-type connecting ball valve. Background Technology

[0002] A ball valve is one of the valves used to control fluid flow. Its unique feature is that it uses the rotational orientation of a hollow ball to control the fluid opening. In order to achieve fluid control, a ball valve must be installed at the pipe port.

[0003] In the existing technology, ball valves on the market are connected to the pipeline by flanges and bolts. Although this method can be used for fixed installation, the removal and installation of a large number of bolts inevitably leads to cumbersome disassembly and assembly. In order to avoid such problems, a socket-type connection ball valve is proposed to solve the existing problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a socket-type ball valve, which solves the problem of cumbersome disassembly and assembly associated with flange and bolt installation of ball valves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a socket-type ball valve, comprising a ball valve body and a ball valve handle, wherein the ball valve handle is disposed on the top of the ball valve body, an inner sleeve is disposed on one side of the ball valve body, and a first thread adapted to the ball valve body is disposed on one side of the surface of the inner sleeve, a valve interface is disposed on one side of the valve interface, an annular conical inclined surface is provided on one side of the valve interface, and a second thread is provided on the other side of the surface of the inner sleeve, wherein an internal threaded external connector is threadedly connected to the surface of the second thread, and a conical ring plate matching the annular conical inclined surface is fixedly connected to the inner wall of the internal threaded external connector.

[0006] Preferably, a stop block is provided on the top of the ball valve body, a first limiting block is provided on one side of the ball valve handle and behind the stop block, and a second limiting block is provided on the front side of the ball valve handle to be used in conjunction with the stop block.

[0007] Preferably, the surface of the valve interface is provided with a mating groove for use with the inner sleeve.

[0008] Beneficial effects

[0009] This utility model provides a socket-type ball valve. Compared with the prior art, it has the following advantages: This utility model has an inner sleeve threadedly connected to one side of the ball valve body, a valve interface set between the inner sleeve and the internally threaded outer connector, and an annular conical inclined surface and a conical annular plate set between the valve interface and the internally threaded outer connector. This allows the pipeline connection to be completed quickly by the annular compression of the conical annular plate against the annular conical inclined surface through the mating of the internally threaded outer connector and the inner sleeve. The deformation of the conical annular plate tightly binds the pipeline surface, making the installation quick. Correspondingly, the subsequent separation and disassembly from the pipeline is also more convenient. By setting the valve interface between the inner sleeve and the internally threaded outer connector, the valve interface can also be quickly replaced by separating the inner sleeve from the internally threaded outer connector.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a socket-type connecting ball valve, including a ball valve body 1 and a ball valve handle 7, wherein the ball valve handle 7 is disposed on the top of the ball valve body 1.

[0016] Furthermore: To facilitate quick assembly and disassembly of the ball valve body 1 and the pipeline, an inner sleeve 4 is provided on one side of the ball valve body 1, and a first thread 4-1 adapted to the ball valve body 1 is provided on one side of the inner sleeve 4. A valve interface 5 is provided on one side of the inner sleeve 4, and an annular conical inclined surface 5-2 is provided on one side of the valve interface 5. A second thread 4-2 is provided on the other side of the inner sleeve 4. An internal threaded external connector 6 is threadedly connected to the surface of the second thread 4-2, and a conical ring plate 6-1 matching the annular conical inclined surface 5-2 is fixedly connected to the inner wall of the internal threaded external connector 6. A mating groove 5-1 matching the inner sleeve 4 is provided on the surface of the valve interface 5.

[0017] Specifically: To facilitate the limiting control of the ball valve opening, a stop block 1-1 is provided on the top of the ball valve body 1, a first limiting block 7-1 is provided on one side of the ball valve handle 7 and behind the stop block 1-1, and a second limiting block 7-2 is provided on the front side of the ball valve handle 7 to be used in conjunction with the stop block 1-1.

[0018] In use, the inner sleeve 4 is fixedly installed on the side of the ball valve body 1 by connecting the first thread 4-1 to the inner wall of the side connecting end. Then, the left end of the valve port 5 is inserted into the inner sleeve 4. Then, the inner threaded outer connector 6, the valve port 5, the inner sleeve 4 and the ball valve body 1 are moved toward the external pipeline in sequence, so that the inner threaded outer connector 6, the valve port 5 and the inner sleeve 4 are fitted onto the outer wall of the pipeline to be connected, so that the external pipeline enters the inner sleeve 4. Then, the inner threaded outer connector 6 is screwed into the second thread 4-2. With the screwing displacement of the inner threaded outer connector 6, the conical ring plate 6-1 in the inner threaded outer connector 6 will move and perform annular compression on the annular conical inclined surface 5-2 in the valve port 5. The annular conical inclined surface 5-2 in the valve port 5 is slightly deformed by the force, so that the valve port 5 is tightly bound to the outer wall of the pipeline, and the connection is completed.
