Description

Technical Field

[0001] The utility model relates to a valve body, and in particular to a distribution valve. Background Art

[0002] A distribution valve is a valve that controls the flow of liquid or gas. It usually has an inlet and is provided with multiple outlets, and can control the on / off and flow rate of individual flow channels.

[0003] Currently, the Chinese patent with the publication number CN219317699U discloses a distribution valve, which includes a driving member, a water inlet valve body, a valve core, and a water outlet valve body. The driving member drives the valve core to rotate. One end of the valve core is provided with a moving valve plate, and the moving valve plate is provided with a water passing port. The water inlet valve body forms a water inlet cavity, and the water outlet valve body forms three water outlet ports. The driving member drives the valve plate to rotate, so that the water passing port communicates with any one of the three water outlet ports. A connecting portion is also provided in the middle of the valve plate.

[0004] The above patent still has deficiencies. To improve the sealing degree, usually the valve plate is made of elastic rubber. When the valve plate presses against the water outlet port, it undergoes a certain deformation to ensure the sealing performance. However, the connecting portion of the above valve plate is arranged in the middle of the valve plate. When the connecting portion is pressed downwards, only the middle part of the valve plate is stressed, and the pressure of the edge of the valve plate on the water outlet port is small, resulting in insufficient sealing performance. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a distribution valve, which has the advantage of good sealing performance.

[0006] To solve the above technical problems, the technical solution of the utility model is: a distribution valve, which includes a valve body and a driving motor. The driving motor is arranged at the upper end of the valve body. A valve cavity is opened in the valve body. A water inlet is arranged at the side end of the valve cavity, and a plurality of water outlets are arranged at the bottom of the valve cavity. The output end of the driving motor is provided with a driving rod, and an installation disk is arranged at the bottom of the driving rod. A sealing member is arranged at the bottom of the installation disk. The sealing member is closely attached to the plurality of water outlets. Through holes that are vertically aligned are respectively opened on the installation disk and the sealing member. The driving motor drives the installation disk and the sealing member to rotate, so that the through hole can communicate with one of the water outlets.

[0007] By the above technical means, the sealing member is pressed on the water outlet port through the installation rack, thereby ensuring the sealing performance of the water outlet port and making the sealing more stable. By opening the through holes and driving the installation disk and the sealing member to rotate through the driving motor, the water outlet port to be communicated can be selected.

[0008] Preferably, the sealing member includes a diaphragm, and the diaphragm is detachably arranged on the installation disk.

[0009] By means of the above technical means, the diaphragm is detachably arranged on the mounting plate, so as to facilitate the replacement and repair of the diaphragm and reduce the maintenance cost.

[0010] Preferably, mounting holes are formed in the mounting plate, elastic buckles are arranged on the top of the diaphragm, and the diaphragm is fixed on the mounting plate through the elastic buckles.

[0011] By means of the above technical means, the elastic buckles pass through the mounting holes, thus completing the detachable installation of the diaphragm.

[0012] Preferably, a convex ring is further arranged in the middle of the mounting plate, a through hole for the convex ring to pass through is formed in the middle of the diaphragm, concave patterns are arranged on the lower end surface of the convex ring, inclined blocks are arranged on the bottom surface of the valve cavity, and a spring is further arranged between the driving rod and the mounting plate.

[0013] By means of the above technical means, through the cooperation between the concave patterns and the inclined blocks, the mounting plate moves upward by a certain part during rotation, thereby reducing the deformation degree of the diaphragm, reducing the friction force between the diaphragm and the water outlet, preventing excessive friction during the rotation of the diaphragm, and driving the mounting plate to press the diaphragm tightly by setting a spring.

[0014] Preferably, a convex ring is arranged at the top of the water outlet, and the sealant abuts against the convex ring.

[0015] By means of the above technical means, by setting the convex ring, the contact area between the water outlet and the sealant is reduced, and the friction force is further reduced.

[0016] Preferably, the valve body includes a bottom shell and a top cover, the bottom shell and the top cover are fixed by screws, and a guiding baffle is further arranged at the bottom of the top cover, and the guiding baffle is arranged at the side end of the water inlet.

[0017] By means of the above technical means, by setting the guiding baffle, while reducing the water flow impact force, the water body is guided to a certain extent.

[0018] Preferably, a sealing rod is further arranged between the driving rod and the mounting plate, square grooves and square rods are respectively arranged at the top and bottom of the sealing rod, the top of the driving rod is square and is matched with the square groove, the mounting plate is fixed to the square rod, and a sealing ring and a sealing gasket are further sleeved on the sealing rod.

[0019] By means of the above technical means, by setting the sealing ring and the sealing gasket, the water body is prevented from entering the driving motor, and the sealing performance is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0027] A distribution valve includes a valve body 1 and a drive motor 2. The drive motor 2 is arranged at the upper end of the valve body 1. The valve body 1 includes a bottom shell 3 and a top cover 4. The bottom shell 3 and the top cover 4 are fixed by screws. A valve cavity 5 is provided in the bottom shell 3 and the top cover 4. A water inlet 6 is provided at the side end of the valve cavity 5. Three water outlets 7 are provided at the bottom of the valve cavity 5. A guide baffle 8 is also provided at the bottom of the top cover 4. The guide baffle 8 is provided at the side end of the water inlet 6 to guide the water entering the valve cavity 5 through the water inlet 6. A drive rod 9 is provided at the output end of the drive motor 2. A hole for the drive rod 9 to pass through is provided on the top cover 4. A sealing rod 10 is provided at the bottom of the drive rod 9. A mounting plate 11 is provided at the bottom of the sealing rod 10. A sealing member 12 is provided at the bottom of the mounting plate 11.

[0028] The top and bottom of the sealing rod 10 are respectively provided with a square groove 13 and a square rod 14. The top of the driving rod 9 is square and is inserted into the square groove 13, so that the sealing rod 10 and the driving rod 9 rotate coaxially. A square hole is opened in the middle of the mounting plate 11 to cooperate with the square rod 14, so that the mounting plate 11 and the sealing rod 10 rotate coaxially. The sealing rod 10 is also provided with a sealing ring 15 and a sealing ring 16. The sealing ring 15 and the sealing ring 16 are used to ensure that water does not leak to the driving motor 2.

[0029] A seal 12 is provided at the bottom of the mounting disk 11. The seal 12 includes a diaphragm 17, which is made of rubber. The diaphragm 17 is against the three water outlets 7. The driving motor 2 drives the mounting disk 11 and the seal 12 to rotate. Aligned water holes 18 are opened through the mounting disk 11 and the seal 12. When the water hole 18 rotates to a certain water outlet 7, water flows into this water outlet 7. By providing the elastic diaphragm 17, the sealing of the water outlet 7 is ensured, and the seal is made more stable.

[0030] The diaphragm 17 is detachably mounted on the mounting plate 11 . A mounting hole 20 is provided on the mounting plate 11 . An elastic undercut 19 is provided on the top of the diaphragm 17 . The elastic undercut 19 is integrally formed with the diaphragm 17 and is conical in shape. The elastic undercut 19 is deformed when passing through the mounting hole 20 and recovers after passing through, thereby fixing the diaphragm 17 on the mounting plate 11 .

[0031] Four convex rings 21 are provided at the bottom of the valve chamber 5. The four convex rings 21 are arranged in a 90° annular array, three of which are respectively arranged above the three water outlets 7. The diaphragm 17 is against the convex rings 21. A convex ring 22 is also provided in the middle of the mounting plate 11. A through hole 23 for the convex ring 22 to pass through is provided in the middle of the diaphragm 17. The lower end surface of the convex ring 22 is provided with four concave grooves 24. Four inclined blocks 25 are provided on the bottom surface of the valve chamber 5. The convex grooves and the inclined blocks 25 are both arranged at a position staggered with the water outlet 7. A spring 26 is also provided between the drive rod 9 and the mounting plate 11. When the drive motor 2 drives the diaphragm 17 and the mounting plate 11 to rotate so that the water hole 1 When 8 is connected to the water outlet 7, the inclined block 25 is stuck in the groove 24. At this time, the spring 26 drives the diaphragm 17 to press the convex ring 21. When the drive motor 2 drives the diaphragm 17 to rotate and the water hole 18 moves between the two water outlets 7, the inclined block 25 disengages from the groove 24, causing the mounting plate 11 to move upward a certain distance as a whole, thereby reducing the friction between the diaphragm 17 and the convex ring 21 during the rotation of the diaphragm 17 and increasing the service life of the diaphragm 17. A solenoid valve is provided on the outside of the water inlet 6. The solenoid valve needs to be closed before the diaphragm 17 rotates. When the mounting plate 11 moves upward, it prevents or reduces the outflow of water from the gap between the diaphragm 17 and the convex ring 21.

[0032] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
