Description

Technical Field

[0001] The utility model relates to the technical field of valve accessories, and particularly relates to a rotary multi-functional valve core. Background Art

[0002] A butterfly valve, also called a flap valve, is a simple regulating valve. The butterfly plate is the valve core of the butterfly valve, generally in a disc shape. Rotating around the butterfly plate can achieve the effect of opening or closing. The ordinary butterfly plate has a simple structure and single function.

[0003] The butterfly plate disclosed in the publication number CN211315158U includes a valve stem seat part for passing through the valve stem and wing plate parts on both sides of the valve stem seat part. A plurality of flow guiding rib plates are fixedly arranged on the wing plate parts. The length direction of the flow guiding rib plates is perpendicular to the central axis of the valve stem seat part, and the height direction of the flow guiding rib plates is perpendicular to the wing plate parts; the flow guiding rib plates are integrally connected with the valve stem seat part and the wing plate parts respectively. The flow guiding rib plates can play a role in medium diversion or interference with vortices when the butterfly plate is opened, reduce the erosion of the medium on the valve seat, and enhance the overall service life of the butterfly valve. The flow guiding rib plates have the function of reinforcing ribs and can enhance the compressive strength and structural strength of the butterfly plate.

[0004] The butterfly plate provided by the above scheme has certain deficiencies in use. Since many valves are in a closed state for a long time, dirt is likely to adhere to the connection between the butterfly plate and the valve body, and it is very laborious to open again. Therefore, a rotary multi-functional valve core is needed to help solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a rotary multi-functional valve core, which solves the problem that since many valves are in a closed state for a long time, dirt is likely to adhere to the connection between the butterfly plate and the valve body, and it is very laborious to open again.

[0025] The following further elaborates on the above and other technical features and advantages of the present utility model in conjunction with the accompanying drawings.

[0026] This embodiment provides a technical solution: a rotary multi-functional valve core, as Figures 1-4 shown, comprising a butterfly plate 1, a brake disc 2, a diversion pipe group 3 and a rotating assembly 4.

[0027] The brake disc 2 is fixedly installed on one side of the butterfly plate 1 through a gasket ring at the edge. A control groove 5 is provided at the center position of the brake disc 2. A plurality of accommodating grooves 6 are evenly arranged in a ring shape between the control groove 5 and the outer wall of the brake disc 2. A drainage control assembly 7 for controlling the discharge of the dissolving agent is arranged in the accommodating groove 6. A sealing cover plate 8 is installed on the front side of the brake disc 2 through bolts.

[0028] The diversion pipe group 3 is arranged on the top of the brake disc 2. The cooperation between the diversion pipe group 3 and the brake disc 2 can periodically spray the pipeline dissolving agent to the edge position of the butterfly plate 1, thereby preventing the situation that the butterfly plate 1 is difficult to rotate due to dirt adhering to the connection between the butterfly plate 1 and the valve body.

[0029] Specifically, as Figures 1-3 shown, the drainage control assembly 7 includes a drainage block 701, a control flap 702 and a limit spring 703. The drainage block 701 is clamped in the accommodating groove 6, so it can play a sealing role to prevent the solution in the pipeline from entering the brake disc 2. One end of the control flap 702 is installed on one side of the drainage block 701 and the other end is arranged in the control groove 5. The limit spring 703 is installed between the control flap 702 and the inner wall of the control groove 5, and the control flap 702 can be limited by the limit spring 703.

[0030] Further, a plurality of liquid discharge grooves 9 are formed in the discharge block 701. One side of the liquid discharge groove 9 is attached to the inner wall of the accommodation groove 6. An installation groove 10 is formed above the brake disc 2. The diversion pipe group 3 is fixedly installed in the installation groove 10. A liquid discharge hole 11 is formed between the inner walls of the installation groove 10 and the control groove 5. The diversion pipe group 3 includes a liquid storage cylinder 301 and a discharge pipe 302. A liquid storage cavity is formed in the liquid storage cylinder 301 and a placement groove is formed at the top. The discharge pipe 302 is installed at the bottom of the liquid storage cavity and the bottom is installed in the installation groove 10. The pipeline solvent in the liquid storage cylinder 301 can enter the brake disc 2 through the discharge pipe 302 and the liquid discharge hole 11.

[0031] Furthermore, a liquid inlet pipe 12 is installed on one side of the liquid storage cavity. A one-way valve 13 is installed on the liquid inlet pipe 12. The addition of the pipeline solvent can be conveniently controlled through the one-way valve 13. A control oil cylinder 14 is installed in the placement groove. A sealing push plate 15 installed at the output end of the control oil cylinder 14 is arranged in the liquid storage cavity. The control oil cylinder 14 can drive the sealing push plate 15 to move up and down to conveniently push the pipeline solvent downward.

[0032] The complete operation of spraying the pipeline solvent is as follows: Connect the pipeline solvent container to the liquid inlet pipe 12 through a pipeline, and then connect the control oil cylinder 14 to an external power supply. The control oil cylinder 14 can drive the sealing push plate 15 to continuously move up and down reciprocally. When the sealing push plate 15 moves downward, it can press the pipeline solvent into the brake disc 2, and under the action of pressure, it can push each control flap 702 to squeeze the limit spring 703. Therefore, the control flap 702 can push the discharge block 701 to move outward. Subsequently, the liquid discharge hole 11 can move out of the accommodation groove 6. Therefore, the pipeline solvent in the brake disc 2 can be discharged through the liquid discharge holes 11 at each part and sprayed onto the connection between the butterfly plate 1 and the valve body from all directions, thereby helping to dissolve the dirt at the connection. When the sealing push plate 15 moves upward, a negative pressure is generated in the liquid storage cavity. Each discharge block 701 in the brake disc 2 moves back to the accommodation groove 6, and at the same time, under the action of negative pressure suction, the pipeline solvent can be sucked into the liquid storage cavity through the liquid inlet pipe 12 to complete the replenishment of the pipeline solvent. Then, repeat the above operation several times.

[0033] Specifically, the rotation assembly 4 is used to control the rotation of the brake disc 2 and the butterfly plate 1. The rotation assembly 4 is arranged on the top of the diversion pipe group 3. The rotation assembly 4 includes a rotating rod 401 and a handwheel 402. The rotating rod 401 is installed on the top of the diversion pipe group 3. The handwheel 402 is installed on the top of the rotating rod 401. By rotating the handwheel 402, the rotating rod 401, the diversion pipe group 3, the brake disc 2 and the butterfly plate 1 can be driven to rotate, thereby controlling the opening and closing of the valve body.

[0034] The above are only the preferred embodiments of the present utility model, which are illustrative rather than restrictive to the present utility model. Those skilled in the art understand that many changes, modifications, or even equivalents can be made to it within the spirit and scope defined by the claims of the present utility model, but all of them will fall within the protection scope of the present utility model.
