Description

Technical Field

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

[0002] Ball valves are a common type of valve widely used in various fluid control systems. Their main feature is that they control the flow of fluid through a spherical valve core. The diameter of the ball determines the flow of fluid. When in use, ball valves need to be installed on pipelines.

[0003] However, when connecting existing pipes to ball valves, threads are cut into the pipes to connect the ball valves and pipes. In order to ensure a seal, raw rubber tape needs to be wrapped between the ball valves and pipes. This not only makes the connection process cumbersome, but also requires re-wrapping raw rubber tape after the ball valves are disassembled and reassembled, resulting in low efficiency of ball valve maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a well-sealed ball valve connection pipe with the advantages of good sealing performance and easy maintenance. It solves the problem that when connecting the ball valve to the pipe, threads are cut on the pipe to connect the ball valve and the pipe. In order to ensure the sealing, raw rubber tape needs to be wrapped between the ball valve and the pipe. This not only makes the connection process cumbersome, but also requires re-wrapping raw rubber tape after the ball valve is disassembled and reassembled, resulting in low efficiency of ball valve maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a well-sealed ball valve connecting pipe, comprising a connecting pipe and a ball valve, wherein a connecting mechanism is provided between the connecting pipe and the ball valve;

[0006] The connecting mechanism includes a threaded sleeve that slides onto the surface of the connecting pipe, a slot is provided on the inner surface of the connecting pipe, a threaded connecting pipe is fixedly installed on the surface of the ball valve, and a plug pipe is fixedly installed at the end of the threaded connecting pipe away from the ball valve.

[0007] Furthermore, the threaded sleeve is adapted to the threaded connecting pipe.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the threaded connection of the threaded sleeve to the surface of the threaded connecting pipe.

[0009] Furthermore, the slot is adapted to the connector tube.

[0010] The advantage of adopting the above-mentioned further solution is that it facilitates the insertion of the connector into the slot.

[0011] Furthermore, the threaded connecting pipe is connected to the inside of the ball valve, and the insertion pipe is connected to the inside of the threaded connecting pipe.

[0012] The advantage of adopting the above-mentioned further solution is that it facilitates the formation of a passage between the ball valve, the threaded connecting pipe, and the plug pipe.

[0013] Furthermore, a rubber sealing ring is fixedly installed on the surface of the insertion tube, and the outer diameter of the rubber sealing ring is adapted to the outer diameter of the connecting tube.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the improvement of the sealing performance between the connecting pipe and the threaded connecting rod.

[0015] Furthermore, two limiting rings are fixedly installed on the surface of the connecting pipe, and the threaded sleeve is located between the two limiting rings.

[0016] The beneficial effect of adopting the above-mentioned further solution is that setting a limit ring facilitates the limiting of the threaded sleeve.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] This well-sealed ball valve connecting pipe utilizes a connecting mechanism between the connecting pipe and the ball valve. During use, the connection between the connecting pipe and the ball valve can be achieved using a slot and a plug pipe. No Teflon tape is required for sealing during connection. Furthermore, a threaded sleeve and a threaded connecting pipe are used to secure the connecting pipe and the ball valve. This solves the problem of existing pipe-to-pipe connections that involve threads on the pipe, requiring Teflon tape to be wrapped between the ball valve and pipe to ensure a seal. This not only makes the connection process cumbersome but also necessitates re-wrapping Teflon tape after disassembly and reassembly, leading to low maintenance efficiency for the ball valve.
