Because the end of the branch part 52 has a vertical part, the pressure P can generate a pressure component in the horizontal direction perpendicular to the vertical part, compared with the traditional Y-shaped sealing ring which has no vertical part and causes a smaller pressure component in the horizontal direction, the contact between the Y-shaped sealing ring 5 and the joint of the inner surface of the water inlet valve body 2 and the outer surface of the transmission shaft 4 is tighter, which is beneficial to improving the sealing performance and the reliability.
Fig. 6 shows the different relative positions of the outlet valve body 1 according to the invention in operation with the water distribution disc 3. In the initial state, the water diversion hole 31 is not overlapped with the flushing flow channel 11 (not shown), fluid (such as water, cleaning fluid and the like) enters the valve cavity from the water inlet flow channel 21 of the water inlet valve body 2, when the valve cavity is filled with the fluid, the fluid keeps the state that the valve cavity is full due to the sealing arrangement of the transmission shaft 4 relative to the valve cavity, the fluid cannot continuously enter the valve cavity until the transmission shaft 4 starts to rotate, the water diversion disc 3 is driven to rotate around the rotation axis 10, the water diversion hole 31 is overlapped with different parts of the flushing flow channel 11 along with the rotation of the water diversion disc 3, the fluid in the valve cavity can enter the flushing flow channel outlet pipe 16 through the water diversion hole 31 and the flushing flow channel 11 under the effect of external pressure, finally the water outlet valve body 1 is discharged from the flushing flow channel outlet pipe 16, and along with the rotation of the water diversion disc 3, the size of the actual water outlet formed by the overlapped part of the water diversion hole 31 and the flushing flow channel 11 can be changed, and the size of the fluid flow of the discharged out of the valve body 1 is further changed, so that stepless adjustment of water supply flow and water supply pressure is realized. In addition, the motor 8 rotates at different angles, the water diversion holes 31 can be aligned with different water outlet pipes (the flushing flow channel water outlet pipe 16 or the self-cleaning flow channel water outlet pipe 18), and fluid can also selectively enter corresponding water outlet branches to realize different functions (flushing, air filling, self-cleaning and the like).
Fig. 7 shows a graph of a simulation experiment of the flow rate of the diverter valve according to the present invention with the change of the angle θ, fig. 7 simulates two flow channel width W and depth H setting modes, the width W of the flushing flow channel of the diverter valve of the first mode linearly changes with the angle θ, the depth H is 0, and the size of the flow channel of the diverter valve of the second mode changes with the angle θ satisfies the relationship described in the above relation. Fig. 8 is a simulation graph of the width W and depth H dimensions of a flush channel according to a second embodiment of the invention as a function of angle θ. As can be seen from fig. 7, the outlet flow rate increases with increasing angle, but in the outlet valve of the first mode, in the interval from 70 degrees to 90 degrees, the outlet flow rate fluctuates from the linear, so that the water flow in the flushing flow channel 11 is unstable, and the flow state is changed drastically to generate strong flow turbulence, so that the vibration noise of the water distributing valve is large. As can be seen from fig. 8, the variation of the water flow rate of the second mode along with the angle θ is approximately linear, because the width of the flushing flow channel 11 is at least the square or more of θ, and the height is at least the square or more of θ, the flushing flow channel according to the above design size has a good flow guiding effect on the water flow in the tank, so that the kinetic energy loss in the tank is effectively reduced, especially the turbulence intensity of the water flow in the flushing flow channel in the range of 70 degrees to 90 degrees is greatly reduced, thereby eliminating the flow fluctuation phenomenon, reducing the vibration noise, and improving the use comfort of customers.
The diverter valve as described above may be used in a toilet bowl, and a user may select among at least three modes of operation: a normal flushing mode, an aerated flushing mode, a self-cleaning mode, etc. When the toilet is in operation, fluid (such as water, cleaning liquid and the like) can enter from the water inlet pipe and fill the valve cavity of the water diversion valve, the controller (not shown) controls the motor 8 to operate, drives the transmission shaft 4 and the water diversion disk 3 to rotate, the motor 8 rotates at different angles, and the water diversion holes 31 can be aligned with different water outlet pipes (the flushing flow passage water outlet pipe 16 or the self-cleaning flow passage water outlet pipe 18), so that the fluid can selectively enter the corresponding water outlet branch.
In the normal flushing mode, the air inlet pipe 17 of the air-entrapping channel of the water outlet valve body 1 is not ventilated, the water diversion hole 31 is aligned to the water outlet pipe 16 of the flushing channel, the fluid discharged from the water outlet pipe 16 of the flushing channel is pure fluid without gas, and meanwhile, the size of an actual water outlet formed by the overlapping part of the water diversion hole 31 and the flushing channel 11 can be changed, so that the size of the fluid flow discharged out of the water outlet valve body 1 is changed, and the stepless regulation of the water supply flow and the water supply pressure is realized.
In the aeration flushing mode, the aeration channel air inlet pipe 17 of the water outlet valve body 1 is filled with gas (such as air), the water diversion hole 31 is aligned to the flushing channel water outlet pipe 16, the gas enters the aeration channel 13 communicated with the aeration channel air inlet pipe through the aeration channel air inlet pipe 17, further enters an aeration groove formed by surrounding the second groove 15 of the water outlet valve body 1 and the first groove 33 of the water diversion disk 3 and a rectangular groove 32 on the water diversion disk 3, along with the rotation of the water diversion disk 3, when the rectangular groove 32 is communicated with the air flow channel 12, the gas can enter the air flow channel 12, further enters the flushing channel 11 communicated with the air flow channel 12 and is mixed with fluid in the flushing channel 11, and the fluid discharged from the flushing channel water outlet pipe 16 is gas-liquid mixed fluid containing the gas, and finally is jointly discharged out of the flushing channel water outlet pipe 16. Meanwhile, the size of an actual water outlet formed at the overlapping part of the water diversion holes 31 and the flushing flow channel 11 can be changed, so that the size of the fluid flow discharged out of the water outlet valve body 1 is changed. The mixed fluid of gas and fluid may provide a more comfortable use experience for the user than the discharged fluid of pure fluid.
In the self-cleaning mode, the water diversion holes 31 are aligned with the self-cleaning flow channel water outlet pipe 18, and fluid is discharged from the self-cleaning flow channel water outlet pipe 18 and can be used for daily cleaning of the water diversion valve.
However, the diverter valve is not limited to a toilet bowl, but may be used in other devices where control of the dispensing of fluid is desired.
While the exemplary embodiments of the diverter valve according to the present invention have been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that various modifications and adaptations may be made to the specific embodiments described above and that various combinations of the technical features and structures may be made without departing from the scope of the invention, which is defined in the appended claims.
