[0031] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, as Figures 1-5As shown in the figure, a water diversion valve with adjustable water diversion flow rate includes a valve body 1. Two water outlet pipes 4 are symmetrically formed on the outer wall of the valve body 1. One end of the valve body 1 is integrally formed with a water inlet pipe 3. The inner cavity of the valve body 1 is interconnected with the inner cavities of the water inlet pipe 3 and the water outlet pipes 4. A valve core 5 is rotatably connected inside the valve body 1. A water outlet 6 is formed on the outer wall of the valve core 5, and a water inlet 7 is formed at one end of the valve core 5. An adjustment mechanism for adjusting the fluid direction and flow rate respectively is provided on the valve body 1;

[0033] The adjustment mechanism includes: a flow diversion rotating cylinder 204 arranged at one end of the valve body 1 away from the water inlet pipe 3. The flow diversion rotating cylinder 204 penetrates the valve body 1 and is fixedly connected with the valve core 5. The flow diversion rotating cylinder 204 is rotatably connected with the valve body 1;

[0034] In this embodiment, when in use, through the adjustment mechanism, the limit locking of the valve core 5 can be released, and the valve core 5 can be driven to rotate. At this time, the water outlet 6 moves under the drive of the valve core 5. In this way, according to actual needs, the opening of the water outlet 6 can be moved to the port of one water outlet pipe 4 or the port of the other water outlet pipe 4;

[0035] After that, the valve core 5 is limited and locked again through the adjustment mechanism, effectively avoiding the situation of self-rotation of the valve core 5. At the same time, the fluid can be discharged into the inner cavity of the valve core 5 through the water inlet pipe 3. At this time, the fluid sequentially passes through the drain port and the water outlet 6 into the inner cavity of one water outlet pipe 4, so as to control the direction of the fluid;

[0036] When it is necessary to adjust the fluid flow rate, at this time, through the adjustment mechanism, the size of the port of the water outlet 6 can be adjusted, so as to realize the precise adjustment of the fluid flow rate and further reduce the problem of gradual decline in precision caused by wear;

[0037] In one embodiment, as Figures 1-3 shown, the adjustment mechanism includes: a moving component arranged on the flow diversion rotating cylinder 204;

[0038] The moving component is a moving rotating cylinder 201 slidably sleeved on the outer wall of the flow diversion rotating cylinder 204. The moving rotating cylinder 201 is in contact with the outer wall of one end of the valve body 1;

[0039] A positioning component is arranged on the valve body 1;

[0040] A first limit component is arranged on the flow diversion rotating cylinder 204;

[0041] The positioning component includes: a plurality of positioning card shafts 205 fixedly connected circumferentially and equidistantly to one end of the valve body 1 away from the water inlet pipe 3. The outer walls of the ends of the plurality of positioning card shafts 205 away from the valve body 1 are all hemispherical. The moving rotating cylinder 201 is slidably sleeved on the outer walls of the plurality of positioning card shafts 205. Through the mutual cooperation of the moving component and the positioning component, the moving rotating cylinder 201 can be limited and locked.

[0042] In one embodiment, as Figures 2-5 shown, the first limiting component includes: a limiting retaining ring 202 fixedly connected to one end of the flow splitting rotating cylinder 204 away from the valve body 1. The moving rotating cylinder 201 is slidably sleeved on the outer wall of the limiting retaining ring 202. A plurality of limiting guide plates 208 are fixedly connected circumferentially and equidistantly to the outer wall of the flow splitting rotating cylinder 204. A sliding sleeve groove for the limiting guide plates 208 to slide is provided at the position where the moving rotating cylinder 201 is in contact with the limiting guide plates 208.

[0043] A reset component is provided on the flow splitting rotating cylinder 204.

[0044] A second rotating component is provided on the limiting retaining ring 202.

[0045] The reset component is a spring 209 sleeved on the outer wall of the flow splitting rotating cylinder 204. The spring 209 is in contact with the outer walls of the plurality of limiting guide plates 208. One end of the spring 209 is in contact with the inner wall of the moving rotating cylinder 201, and the other end of the spring 209 is in contact with the outer wall of the limiting retaining ring 202. Through the mutual cooperation of the first limiting component and the reset component, it is possible to prevent the moving rotating cylinder 201 from separating from the positioning card shaft 205 without external force. When the moving rotating cylinder 201 separates from the positioning card shaft 205 under the action of external force, at this time, the flow splitting rotating cylinder 204 can be driven to rotate by rotating the moving rotating cylinder 201.

[0046] In one embodiment, as Figures 1-5 shown, the second rotating component includes: a knob 203 provided at one end of the limiting retaining ring 202 away from the flow splitting rotating cylinder 204. One end of the knob 203 is fixedly connected to a transmission rotating rod 207. The transmission rotating rod 207 passes through the limiting retaining ring 202, the flow splitting rotating cylinder 204, the valve body 1 to the inside of the valve core 5. The transmission rotating rod 207 is rotatably connected to the limiting retaining ring 202, the flow splitting rotating cylinder 204, the valve body 1 and the valve core 5.

[0047] An adjusting component is provided on the transmission rotating rod 207.

[0048] The adjusting component is an adjusting cylinder 206 fixedly connected to one end of the transmission rotating rod 207 away from the knob 203. The adjusting cylinder 206 is located inside the valve core 5. The adjusting cylinder 206 is rotatably connected to the valve core 5. A drain port is provided on the outer wall of the adjusting cylinder 206. One end of the adjusting cylinder 206 is fixedly connected with a sealing rubber ring, and the sealing rubber ring is in contact with the inner wall of the valve core 5. Through the mutual cooperation of the second rotating component and the adjusting component, the convenient adjustment of the fluid flow rate can be realized by the mutual dislocation of the drain port and the port of the water outlet 6;

[0049] A second limiting component is arranged on the adjusting cylinder 206;

[0050] In one embodiment, as Figures 3-5 shown, the second limiting component includes: a plurality of limiting sliders 2010 fixedly connected to one end of the adjusting cylinder 206 at equal circumferential intervals. The plurality of limiting sliders 2010 are all located inside the sealing rubber ring. A limiting chute for the limiting sliders 2010 to slide is provided at the position where the valve core 5 is connected to the limiting sliders 2010. Through the mutual cooperation of the limiting sliders 2010 and the limiting chute, the rotation of the adjusting cylinder 206 can be limited.

[0051] The above embodiment discloses a water distribution valve with adjustable water distribution flow rate. Among them, when in use, the moving cylinder 201 is pulled to slide along the outer walls of the limiting retaining ring 202, the flow dividing cylinder 204, the limiting guide plate 208 and the positioning shaft 205. At this time, the moving cylinder 201 contracts through the moving compression spring 209 until the moving cylinder 201 is separated from the positioning shaft 205, so as to release the clamping limit on the moving cylinder 201;

[0052] After that, the moving cylinder 201 is rotated. At this time, the flow dividing cylinder 204 drives the limiting retaining ring 202 and the valve core 5 to rotate synchronously through the limiting guide plate 208 under the drive of the moving cylinder 201. At the same time, the water outlet 6 is displaced under the drive of the valve core 5. In this way, according to actual needs, the opening of the water outlet 6 can be moved to the port of one water outlet pipe 4 or another water outlet pipe 4. Then the moving cylinder 201 is released. At this time, the spring 209 can push the moving cylinder 201 to reset through rebound. At the same time, the moving cylinder 201 slides and sleeves on the outer wall of the positioning shaft 205 through the movement, so as to lock and lock the moving cylinder 201, effectively avoiding the self-rotation of the valve core 5. At the same time, the fluid can be discharged into the inner cavity of the valve core 5 through the water inlet pipe 3. At this time, the fluid sequentially passes through the drain port and the water outlet 6 into the inner cavity of one water outlet pipe 4, so as to control the direction of the fluid;

[0053] When it is necessary to adjust the fluid flow rate, rotate the knob 203 at this time to drive the transmission rod 207 to rotate. At the same time, drive the adjustment cylinder 206 to rotate synchronously along the inner wall of the valve core 5 under the drive of the transmission rod 207. At the same time, drive the multiple limit sliders 2010 to slide along the inner wall of the limit chute under the drive of the adjustment cylinder 206. In this way, the mutual dislocation between the drain port and the outlet port 6 can be used to change the effective flow cross-sectional area of the fluid, so as to achieve precise adjustment of the fluid flow rate and further reduce the problem of gradual decline in precision caused by wear.

[0054] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
