Description

Technical Field

[0001] This invention relates to the field of valve technology, and in particular to a connector with a self-locking function. Background Technology

[0002] Currently, ball valves are widely used in various fluid transport systems. However, in certain situations, it is necessary to operate and control multiple ball valves to ensure the safe operation of the system. Existing ball valves typically operate independently and lack effective interlocking mechanisms, making them prone to misoperation, which can lead to system failures or safety accidents.

[0003] Therefore, how to design a novel connector with self-locking function to achieve precise interlocking between multiple ball valves, prevent misoperation, and improve the reliability and safety of the system has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a connector with a self-locking function to solve the problems of poor reliability and low safety of existing ball valves.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a connector with a self-locking function, including a valve body. An interlocking assembly is provided at the bottom of the valve body, and two different valve bodies are connected together through the interlocking assembly. A handle assembly is rotatably connected to the side wall of the valve body, and a limiting assembly for limiting the handle assembly is also provided on the side wall of the valve body. When the handle assembly rotates, it drives the valve core inside the valve body to rotate. A tail end piece is rotatably connected to the top of the valve body.

[0007] Optionally, the interlocking assembly includes a connecting groove and a hook foot. The connecting groove is formed at the bottom of the valve body, and the hook foot is integrally formed at the bottom of the valve body and located around the connecting groove. The hook foot and the connecting groove are matched.

[0008] Optionally, a handle connector is integrally formed on the side wall of the valve body. The handle connector is provided with a first mounting channel and a second mounting channel. The connecting end of the handle assembly passes through the first mounting channel and is connected to the valve core. The second mounting channel is connected to the connecting groove, and the limiting component is installed in the second mounting channel.

[0009] A valve core stabilizer is integrally formed on the side wall of the valve body. A third mounting channel is provided in the valve core stabilizer. The third mounting channel and the first mounting channel are coaxially arranged. A stabilizing component for stabilizing the valve core is installed in the third mounting channel.

[0010] The valve body has a wire insertion port on its side wall and an annular groove for installing a wire on its inner wall. The wire insertion port and the annular groove correspond to each other, and the wire is used to limit the tail end piece.

[0011] Optionally, the handle connector is further provided with a first limiting hole and a second limiting hole for limiting the handle assembly.

[0012] Optionally, the handle assembly includes an inner knob block and an outer knob block. The inner knob block has a protrusion at its center, and the body of the protrusion is rotatably disposed in the first mounting channel. The protrusion and the valve core are engaged. A bolt is threaded onto the inner knob block, and the body of the bolt is threaded onto the valve core after passing through a pre-drilled hole at the center of the protrusion.

[0013] The inner knob block is equipped with a first magnetic ring, and the outer knob block is equipped with a second magnetic ring. The inner knob block and the outer knob block are attracted together by the two magnetic rings. The inner knob block is equipped with a limit screw, and the other end of the limit screw is connected to the third limit hole of the outer knob block.

[0014] The outer knob block is equipped with a first limiting pin, which corresponds to the first limiting hole and the second limiting hole respectively. The inner knob block is provided with a through hole for the first limiting pin to pass through.

[0015] Optionally, the limiting component includes a third magnetic ring and a second limiting pin. The third magnetic ring is pasted in the second mounting channel, and an iron block is installed on the body of the second limiting pin. The iron block is adsorbed onto the third magnetic ring.

[0016] An arc-shaped groove is provided on the inner knob block. One end of the arc-shaped groove is connected to a limit pin insertion port. One end of the second limit pin is located in the connecting groove, and the other end is partially embedded in the limit pin insertion port. When the two valve bodies are connected together through the interlocking assembly, the hook on one valve body pushes the second limit pin on the other valve body out of the connecting groove. At this time, the end of the second limit pin is fully embedded in the limit pin insertion port.

[0017] Optionally, the stabilizing component includes a spring and a sleeve, the sleeve being fitted onto the spring, one end of the spring abutting against the inner wall of the third mounting channel, and the other end abutting against the sleeve, the body of the sleeve being movably connected within the third mounting channel, and the sleeve and the valve core being rotatably connected.

[0018] Optionally, two O-rings for sealing are connected to the tail end piece.

[0019] Optionally, both the protrusion and the bolt are fitted with O-rings for sealing.

[0020] Optionally, a sealing ring is installed at the bottom of the valve body.

[0021] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0022] 1) When operating a single unit, the handle cannot drive the valve core to open, thus avoiding misoperation.

[0023] 2) It provides a reliable interlock function, which effectively solves the problem of safety accidents caused by misoperation or system failure.

[0024] 3) The structure is reasonably designed and the interlocking components are sensitive and can quickly respond to changes in the ball valve's state.

[0025] 4) Connectors with self-locking function of appropriate size can be selected according to different application scenarios, which has high flexibility and adaptability. Attached Figure Description

[0052] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] like Figure 1-15As shown, a connector with a self-locking function includes a valve body 1. An interlocking assembly 2 is provided at the bottom of the valve body 1, and two different valve bodies 1 are connected together through the interlocking assembly 2. A handle assembly 3 is rotatably connected to the side wall of the valve body 1. A limiting assembly 4 for limiting the handle assembly 3 is also provided on the side wall of the valve body 1. When the handle assembly 3 rotates, it drives the valve core 5 inside the valve body 1 to rotate. A tail end piece 6 is rotatably connected to the top of the valve body 1.

[0054] Specifically, the interlocking assembly 2 includes a connecting groove 21 and a hook 22. The connecting groove 21 is formed at the bottom of the valve body 1, and the hook 22 is integrally formed at the bottom of the valve body 1 and located around the connecting groove 21. The hook 22 and the connecting groove 21 are matched.

[0055] Specifically, a handle connector 11 is integrally formed on the side wall of the valve body 1. The handle connector 11 is provided with a first mounting channel 111 and a second mounting channel 112. The connecting end of the handle assembly 3 passes through the first mounting channel 111 and is connected to the valve core 5. The second mounting channel 112 is connected to the connecting groove 21, and the limiting assembly 4 is installed in the second mounting channel 112.

[0056] A valve core stabilizer 12 is integrally formed on the side wall of the valve body 1. A third mounting channel 121 is provided in the valve core stabilizer 12. The third mounting channel 121 and the first mounting channel 111 are coaxially arranged. A stabilizing component 7 for stabilizing the valve core 5 is installed in the third mounting channel 121.

[0057] The valve body 1 is provided with a wire insertion port 13 on its side wall and an annular groove 131 for installing a wire 8 on its inner wall. The wire insertion port 13 and the annular groove 131 correspond to each other. The wire 8 is used to limit the tail end piece 6.

[0058] Specifically, the handle connector 11 is also provided with a first limiting hole 113 and a second limiting hole 114 for limiting the handle assembly 3.

[0059] Specifically, the handle assembly 3 includes an inner knob block 31 and an outer knob block 32. The inner knob block 31 has a protrusion 311 at its center. The body of the protrusion 311 is rotatably disposed in the first mounting channel 111. The protrusion 311 and the valve core 5 are engaged. A bolt 33 is threadedly connected to the inner knob block 31. The body of the bolt 33 passes through the reserved through hole at the center of the protrusion 311 and is threadedly connected to the valve core 5.

[0060] The inner knob block 31 is equipped with a first magnetic ring 34, and the outer knob block 32 is equipped with a second magnetic ring 35. The inner knob block 31 and the outer knob block 32 are attracted together by the two magnetic rings. The inner knob block 31 is equipped with a limiting screw 36, and the other end of the limiting screw 36 is connected to the third limiting hole 321 of the outer knob block 32.

[0061] The outer knob block 32 is equipped with a first limiting pin 37, which corresponds to the first limiting hole 113 and the second limiting hole 114 respectively. The inner knob block 31 is provided with a through hole for the first limiting pin 37 to pass through.

[0062] Specifically, the limiting component 4 includes a third magnetic ring 41 and a second limiting pin 42. The third magnetic ring 41 is pasted in the second mounting channel 112. An iron block 421 is installed on the body of the second limiting pin 42, and the iron block 421 is adsorbed on the third magnetic ring 41.

[0063] An arc-shaped groove 312 is provided on the inner knob block 31. One end of the arc-shaped groove 312 is connected to a limit pin insertion port 313. One end of the second limit pin 42 is located in the connecting groove 21, and the other end is partially embedded in the limit pin insertion port 313. When the two valve bodies 1 are connected together through the interlocking assembly 2, the hook foot 22 on one valve body 1 pushes the second limit pin 42 on the other valve body 1 out of the connecting groove 21. At this time, the end of the second limit pin 42 is completely embedded in the limit pin insertion port 313.

[0064] Interlocking principle: When operating a single connector with self-locking function, that is, when connecting the tail end piece 6 on a single ball valve to the liquid flow pipeline, under the action of the third magnetic ring 41, the iron block 421 on the second limit pin 42 is attracted to the third magnetic ring 41. At this time, the inner end of the second limit pin 42 is located in the connecting groove 21, and the outer end is half-embedded in the limit pin insertion port 313. At this time, the second limit pin 42 cannot slide in the arc groove 312. The second limit pin 42 completes the limiting function of the inner knob block 31, preventing the inner knob block 31 from rotating. At this time, the valve core 5 is in a blocked state, which can prevent liquid leakage caused by the operator's mistaken rotation of the handle assembly 3, and improve the safety of the connector with self-locking function.

[0065] When two self-locking connectors are interlocked together, the hook 22 on one valve body 1 pushes the second limiting pin 42 on the other valve body 1 out of the connecting groove 21. At this time, the end of the second limiting pin 42 is fully embedded in the limiting pin insertion port 313. The second limiting pin 42 can slide in the arc groove 312. The operator can rotate the handle assembly 3 to allow the liquid to flow in the pipeline.

[0066] In practical implementation, in order to facilitate the hook foot 22 to push the second limit pin 42 out of the connecting groove 21, the contact surface between the hook foot 22 and the second limit pin 42 is set to be arc-shaped. When the two connectors with self-locking function are rotated and interlocked, the hook foot 22 pushes the second limit pin 42 out of the connecting groove 21.

[0067] Specifically, those skilled in the art can also replace the third magnetic ring 41 with a spring, and use the spring to connect the iron block 421 and the second mounting channel 112, so that the spring provides the force required for the second limit pin 42 to reset.

[0068] Specifically, the stabilizing component 7 includes a spring 71 and a sleeve 72. The sleeve 72 is sleeved on the spring 71. One end of the spring 71 abuts against the inner wall of the third mounting channel 121, and the other end abuts against the sleeve 72. The body of the sleeve 72 is movably connected within the third mounting channel 121, and the sleeve 72 and the valve core 5 are rotatably connected.

[0069] Specifically, the tail end piece 6 is connected to two O-rings for sealing.

[0070] Specifically, both the protrusion 311 and the bolt 33 are fitted with O-rings for sealing.

[0071] Specifically, a sealing ring 14 is installed at the bottom of the valve body 1.

[0072] Two sealing rings 14 are provided, one for sealing between valve core 5 and valve body 1, and the other for sealing between two different valve bodies 1.

[0073] The working principle of the self-locking connector of the present invention is as follows:

[0074] Interlocking principle: When operating a single connector with self-locking function, that is, when connecting the tail end piece 6 on a single ball valve to the liquid flow pipeline, under the action of the third magnetic ring 41, the iron block 421 on the second limit pin 42 is attracted to the third magnetic ring 41. At this time, the inner end of the second limit pin 42 is located in the connecting groove 21, and the outer end is half-embedded in the limit pin insertion port 313. At this time, the second limit pin 42 cannot slide in the arc groove 312. The second limit pin 42 completes the limiting function of the inner knob block 31, preventing the inner knob block 31 from rotating. At this time, the valve core 5 is in a blocked state, which can prevent liquid leakage caused by the operator's mistaken rotation of the handle assembly 3, and improve the safety of the connector with self-locking function.

[0075] When two self-locking connectors are interlocked together, the hook 22 on one valve body 1 pushes the second limiting pin 42 on the other valve body 1 out of the connecting groove 21. At this time, the end of the second limiting pin 42 is fully embedded in the limiting pin insertion port 313. The second limiting pin 42 can slide in the arc groove 312. The operator can rotate the handle assembly 3 to allow the liquid to flow in the pipeline.

[0076] Mistake-proof principle: When rotating the handle assembly 3, the outer knob block 32 is pulled outward, and the outer knob block 32 drives the first limit pin 37 to leave the first limit hole 113 or the second limit hole 114. At this time, rotating the outer knob block 32 drives the inner knob block 31 to rotate, and the inner knob block 31 drives the valve core 5 to rotate. When the first limit pin 37 is aligned with the second limit hole 114 or the first limit hole 113, the outer knob block 32 is released. Under the attraction of the two magnetic rings, the outer knob block 32 is attracted to the inner knob block 31. At this time, the first limit pin 37 is inserted into the second limit hole 114 or the first limit hole 113, thus completing the limitation of the handle assembly 3.
