Description

Technical Field

[0001] The present invention relates to the technical field of valves, and in particular to a multi-way water valve spool structure. Background Art

[0002] A water valve is a device that can control the water flow. The control of the water valve can ensure the size, flow rate and velocity of the water flow. Most of the current water valves use a single spool structure, and each single spool mainly functions to control the on-off or proportional adjustment between two pipes. When it comes to the on-off or adjustment of multiple pipes, a valve body needs to be installed between every two pipes for connection. When controlling the pipes, each valve body needs to be controlled separately, and at the same time, the proportional adjustment effect cannot be achieved, increasing the use cost. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-way water valve spool structure to solve the problem that the connection of pipes requires multiple valves for control.

[0004] Based on the technical problems existing in the background art, the present invention proposes a multi-way water valve spool structure, including a main spool, a sub-spool and a valve body. The main spool is concentrically installed in the valve body. A coaxial slot for installing the sub-spool is provided at the center of the bottom of the main spool. The upper end of the valve body is closed by a valve cover, and a liquid distribution plate corresponding to the connection of the pipe orifices is provided at the bottom of the valve body. The main spool and the sub-spool can rotate relative to each other and change the connection of the liquid distribution plate.

[0005] Preferably, there is a spacer layer between the main spool and the valve cover.

[0006] Preferably, the main spool is provided with three fan-shaped communication cavities with a central angle of 90 degrees. Two of the communication cavities are adjacent, and there is a fan-shaped notch with a central angle of 22.5 degrees between the third communication cavity and the adjacent communication cavity, and the notch communicates with the spacer layer.

[0007] Preferably, the bottom of the main spool is connected with a bottom cover, and eight fan-shaped leakage orifices with a central angle of 22.5 degrees are circumferentially distributed on the bottom cover.

[0008] Preferably, the liquid distribution plate is provided with eight groups of fan-shaped large through orifices with an angle of 45 degrees, and one group of large through orifices is divided into two small through orifices.

[0009] Preferably, an external leakage seal is provided below the liquid distribution plate.

[0010] Preferably, the sub-spool is provided with two groups of partition cavities that equally divide the fan-shaped area, and the partition cavities are isolated from each other. The liquid distribution plate is provided with sub-communication orifices corresponding to the connection of the sub-spool. The number of sub-communication orifices is twice the number of partition cavities. After the sub-spool rotates to equally divide the angle of the partition cavities, the connection position of two adjacent sub-communication orifices can be changed.

[0011] Preferably, an actuator is installed above the valve cover, and the actuator is connected to the center of the main valve body through a shaft body.

[0012] Preferably, a limiting member is arranged in the slot, a partition is arranged at the upper end of the auxiliary valve core and abuts against the limiting member, and there is a virtual space between the partition and the limiting member.

[0013] Compared with the prior art, a multi-way water valve core structure proposed by the present invention adopts the above technical solutions and achieves the following technical effects:

[0014] The present invention can achieve various on-off effects through the on-off between two groups of valve cores. The rotation of the main valve core can achieve the effects of an eight-way switching valve and a three-way proportional valve, and the auxiliary valve core can achieve the effect of a three-way proportional valve, thereby realizing various proportional on-off effects.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Embodiment

[0025] Refer to Figures 1 - 8, the present invention provides a multi-way water valve spool structure, including a main spool 1, a secondary spool 2, and a valve body 3. The main spool 1 is concentrically installed inside the valve body 3. A coaxial slot 15 for installing the secondary spool 2 is provided at the center of the bottom of the main spool 1. The upper end of the valve body 3 is closed by a valve cover 4, and a liquid distribution plate 5 corresponding to the pipe connection is provided at the bottom of the valve body 3. The main spool 1 and the secondary spool 2 can rotate relative to each other and change the connection of the liquid distribution plate 5; in this solution, the main spool 1 and the secondary spool 2 can rotate relative to each other. After the main spool 1 rotates, the connection position with the liquid distribution plate 5 can be changed, and the connection direction on the liquid distribution plate 5 can be changed.

[0026] In the specific implementation manner, referring to Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , there is a spacer layer 100 between the main spool 1 and the valve cover 4; the main spool 1 is provided with three fan-shaped communication cavities 11 with a central angle of 90 degrees. Two of the communication cavities 11 are adjacent, and there is a fan-shaped notch 12 with a central angle of 22.5 degrees and communicating with the spacer layer 100 between the third communication cavity 11 and the adjacent communication cavity 11; the bottom of the main spool 1 is connected with a bottom cover 6, and eight fan-shaped leakage ports 61 with a central angle of 22.5 degrees are circumferentially distributed on the bottom cover 6. The rotation angle of the main spool 1 at one time is 22.5 degrees. Since the through cavity of the main spool 1 is a 90-degree central angle, only two leakage ports 61 connected to the same through cavity can be connected. Three through cavities can connect three groups of leakage ports 61, and its two notches 12 are connected through the spacer layer 100, and four groups of connection methods of the leakage ports 61 are formed. Every time the main valve body 3 rotates 22.5 degrees, the position of the through cavity is changed, and then the connection position of the leakage ports 61 is changed, and then multiple connection methods are formed.

[0027] Furthermore, the through cavity can increase the connection scheme by increasing the quantity and reducing the central angle.

[0028] In a further implementation manner, referring to Figure 4 , the liquid distribution plate 5 is provided with eight groups of fan-shaped large through ports 51 with a 45-degree central angle, and one group of large through ports 51 is divided into two small through ports 511; in this solution, the central angle of the large through ports 51 is 45 degrees, and the central angle of the small through ports 511 is 22.5 degrees.

[0029] In a further implementation manner, referring to Figure 2 , Figure 4 , Figure 5, the secondary spool 2 is provided with two sets of partition cavities 21 that are equally divided into fan-shaped regions. The partition cavities 21 are isolated from each other. The liquid distribution disk 5 is provided with secondary through ports 52 corresponding to the connection of the secondary spool 2. The number of secondary through ports 52 is twice the number of partition cavities 21. After the secondary spool 2 rotates and equally divides the angle of the partition cavities 21, the connection positions of two adjacent secondary through ports 52 can be changed. In this solution, the central angle of the partition cavity 21 of the secondary spool 2 is 180 degrees. Therefore, two sets of partition cavities 21 are provided, and the partition cavities 21 correspond to four secondary through ports 52. Every 90-degree rotation of the partition cavity 21 can change the connection position of the secondary through port 52; the rotation of the main valve and the rotation of the secondary valve can achieve multiple connection schemes.

[0030] In the specific implementation manner, referring to Figure 2 , an external leakage seal 7 is provided below the liquid distribution disk 5. In this solution, the external leakage seal 7 is used to improve the sealing effect when docking with the pipe body structure.

[0031] In the specific implementation manner, referring to Figure 1 , an actuator 9 is installed above the valve cover 4. The actuator 9 is connected to the center of the main valve body 3 through a shaft body 8; in this solution, the actuator 9 can drive the main valve body 3 to rotate. The rotation angle of each drive is a multiple of 22.5 degrees. After rotation, the connection positions of the large through port 51 and the small through port 511 of the liquid distribution disk 5 can be changed.

[0032] In the specific implementation manner, referring to Figure 5 、 Figure 6 、 Figure 7 , a limiting member 13 is provided in the slot 15. A partition 22 that abuts against the limiting member 13 is provided at the upper end of the secondary spool 2. There is a virtual position between the partition 22 and the limiting member 13. In this solution, the main spool 1 can drive the secondary spool 2 to rotate. The angle of the virtual position can be designed according to requirements. The virtual position can allow the main spool 1 to rotate a certain angle without affecting the rotation of the secondary spool 2, keeping the secondary spool 2 in a state, so as to realize the rotation of a single spool.

[0033] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
