[0001] The utility model relates to the technical field of multi-way copper valves, and particularly relates to a multi-way copper valve that can adapt to various pipe diameters. Background Technique

[0002] A copper valve is a valve cast from copper and belongs to industrial parts. The maximum allowable working pressure in the valve technical parameters refers to the working pressure at normal temperature. However, the mechanical strength of the valve material decreases with the increase of temperature, so the allowable working pressure of the valve will decrease with the increase of the medium temperature.

[0003] A multi-way valve is a combined valve with two or more commutation structures as the main body. The multi-way valve is a type of valve that changes the on-off relationship of the liquid channels connected to the valve body through the relative movement between the control rod and the valve body. When using the multi-way valve, pipe fittings are sleeved on the water outlet pipe as a medium for transmitting liquid. However, only a small range of pipe diameters are applicable to the water outlet pipe of the multi-way valve, and it cannot cope with the working conditions that require the assembly of various pipe diameters. The adaptability of the water outlet pipe of the multi-way valve is relatively low. Content of the Utility Model

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution for a multi-way copper valve adaptable to multiple pipe diameters: a multi-way copper valve adaptable to multiple pipe diameters, including a valve body 1, an outlet pipe 2 fixedly connected to the outside of the valve body 1, and an adjusting mechanism 3 arranged on the outside of the outlet pipe 2, and the adjusting mechanism 3 is used to adjust the outer diameter of the outlet pipe 2;

[0025] The adjusting mechanism 3 includes a docking assembly and a clamp assembly;

[0026] The docking assembly is used to assist in pre-connecting the outlet pipe 2 and the pipe fitting;

[0027] The clamp assembly is used to lock and fix the outlet pipe 2 and the pipe fitting in the pre-connected state.

[0028] Please pay special attention to Figure 3 , the docking assembly includes a docking part 301, a rubber ring 302, a sealing ring 303, a bracket 305 and a spring 306;

[0029] The docking part 301 is fixedly connected to the top of the outlet pipe 2, the bracket 305 is fixedly connected to the outer wall of the outlet pipe 2, the spring 306 is fixedly installed on the top of the bracket 305, the rubber ring 302 is fixedly connected to the end of the spring 306, and the sealing ring 303 is arranged on the top of the rubber ring 302.

[0030] In this embodiment: When it is necessary to dock the water outlet pipe 2 with a pipe fitting, first move the rubber ring 302 upward. When the rubber ring 302 in the upward movement state stretches the spring 306, the rubber ring 302 in the upward movement state squeezes the docking part 301, and the docking part 301 in the expanded state contracts under the force. At this time, the pipe fitting is sleeved outside the docking part 301, and the pipe fitting is moved downward to the position where it is docked with the water outlet pipe 2. The pipe fitting in the downward movement state squeezes the rubber ring 302, causing the rubber ring 302 to move downward under the force. Then the rubber ring 302 in the downward movement state squeezes the spring 306, causing the spring 306 to be compressed under the force. Since the inner diameter of the docking part 301 gradually decreases from top to bottom, the rubber ring 302 in the downward movement state contacts and squeezes part of the position of the docking part 301, and the docking part 301 in the contracted state expands outward. Then the docking part 301 in the expanded state closely adheres to the inner wall of the pipe fitting, thereby pre-connecting the water outlet pipe 2 and the pipe fitting.

[0031] Please refer specifically to Figure 3 , both the rubber ring 302 and the sealing ring 303 are sleeved outside the docking part 301, and the docking part 301, the rubber ring 302 and the sealing ring 303 are all of elastic structure.

[0032] In this embodiment: When the rubber ring 302 in the downward movement state contacts and squeezes part of the position of the docking part 301, the docking part 301 in the contracted state expands outward. Then the docking part 301 in the expanded state closely adheres to the inner wall of the pipe fitting. And since the sealing ring 303 is of elastic structure, the end of the pipe fitting is closely fitted with the sealing ring 303, avoiding the situation of easy water leakage after the water outlet pipe 2 and the pipe fitting are docked.

[0033] Please refer specifically to Figure 2 , the inner diameter of the docking part 301 gradually decreases from top to bottom. The docking part 301 is a hollow structure with both ends open, and the docking part 301 is internally connected to the water outlet pipe 2.

[0034] In this embodiment: Since the inner diameter of the docking part 301 gradually decreases from top to bottom, the rubber ring 302 in the downward movement state contacts and squeezes part of the position of the docking part 301, the docking part 301 in the contracted state expands outward. Then the docking part 301 in the expanded state closely adheres to the inner wall of the pipe fitting, thereby pre-connecting the water outlet pipe 2 and the pipe fitting.

[0035] Please refer specifically to Figure 4 , the clamp assembly includes a connecting frame 307, a bidirectional stud 308, two clamps 304 and a connecting rod 309;

[0036] The connecting bracket 307 is fixedly connected to the end of the rubber ring 302. The double-headed stud 308 is rotatably connected to the connecting bracket 307. One end of the connecting rod 309 is threadedly connected to the double-headed stud 308, and the clamp 304 is fixedly connected to the other end of the connecting rod 309.

[0037] In this embodiment: By rotating the double-headed stud 308 in the forward direction, the double-headed stud 308 in the forward rotation state drives the two connecting rods 309 to move closer. One connecting rod 309 moves along the positive thread trajectory of the double-headed stud 308, and the other connecting rod 309 moves along the reverse thread trajectory of the double-headed stud 308. The two connecting rods 309 in the closer movement state respectively drive the two clamps 304 to move closer. The two clamps 304 in the closer movement state are closely attached to the outer wall of the pipe fitting, so that the two clamps 304 in the closer movement state lock and fix the outlet pipe 2 in the pre-connection state and the pipe fitting.

[0038] Please refer specifically to Figure 4 , the inner cavity of one end of a connecting rod 309 is provided with an internal thread that engages with the positive thread of the double-headed stud 308, and the inner cavity of one end of the other connecting rod 309 is provided with an internal thread that engages with the reverse thread of the double-headed stud 308.

[0039] In this embodiment: The double-headed stud 308 in the forward rotation state drives the two connecting rods 309 to move closer. One connecting rod 309 moves along the positive thread trajectory of the double-headed stud 308, and the other connecting rod 309 moves along the reverse thread trajectory of the double-headed stud 308. The two connecting rods 309 in the closer movement state respectively drive the two clamps 304 to move closer.

[0040] Please refer specifically to Figure 4 , the clamp 304 has an arc-shaped structure. The rotating double-headed stud 308 is used to drive the two clamps 304 to move closer or farther away respectively through the two connecting rods 309, and the two moving clamps 304 are used to limit and lock the pipe fitting.

[0041] In this embodiment: The two connecting rods 309 in the closer movement state respectively drive the two clamps 304 to move closer. The two clamps 304 in the closer movement state are closely attached to the outer wall of the pipe fitting, so that the two clamps 304 in the closer movement state lock and fix the outlet pipe 2 in the pre-connection state and the pipe fitting.

[0042] Working principle: When it is necessary to dock the water outlet pipe 2 with the pipe fitting, first move the rubber ring 302 upward. The rubber ring 302 in the upward movement state stretches the spring 306, and the rubber ring 302 in the upward movement state squeezes the docking part 301. The docking part 301 in the expanded state shrinks under the force. At this time, the pipe fitting is sleeved on the outside of the docking part 301, and the pipe fitting is moved downward to the position where it is docked with the water outlet pipe 2. The pipe fitting in the downward movement state squeezes the rubber ring 302, causing the rubber ring 302 to move downward under the force. Then the rubber ring 302 in the downward movement state squeezes the spring 306, causing the spring 306 to be compressed under the force. Since the inner wall diameter of the docking part 301 gradually decreases from top to bottom, the rubber ring 302 in the downward movement state contacts and squeezes part of the position of the docking part 301. The docking part 301 in the contracted state expands outward, and the expanded docking part 301 clings to the inner wall of the pipe fitting, thereby pre-connecting the water outlet pipe 2 and the pipe fitting. And because the sealing ring 303 is of an elastic structure, the end of the pipe fitting is closely attached to the sealing ring 303, avoiding the situation of easy water leakage after the water outlet pipe 2 and the pipe fitting are docked.

[0043] At this time, rotate the bidirectional screw 308 forward, so that the bidirectional screw 308 in the forward rotation state drives the two connecting rods 309 to move closer. One connecting rod 309 moves along the positive thread track of the bidirectional screw 308, and the other connecting rod 309 moves along the reverse thread track of the bidirectional screw 308. The two connecting rods 309 in the closer movement state respectively drive the two clamps 304 to move closer. The two clamps 304 in the closer movement state cling to the outer wall of the pipe fitting. Thus, the two clamps 304 in the closer movement state lock and fix the water outlet pipe 2 and the pipe fitting in the pre-connection state. Through the above structure, it is convenient to adjust the outer diameter of the water outlet pipe 2, so that the water outlet pipe 2 can be assembled with pipe fittings of various different pipe diameters.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
