Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a multi-operation structure valve casting. Background Art

[0002] Multi-channel valves can control the flow direction of complex fluid media, allowing customers to control the outflow or inflow of the media in the pipeline according to their own needs. Currently, in the food and pharmaceutical industries, the demand for multi-channel valves is very large, and due to their structural characteristics, multi-channel valves are often used in different working conditions.

[0003] The existing multi-channel valves control the media flow to different channels through a valve core. Since the valve core is rotated for operation, it is easy to have a situation where the rotation is not in place when operating the valve core to turn, which in turn affects the flow direction of the media. Therefore, a multi-operation structure valve casting is needed to facilitate the operation of the valve core to turn in different directions and ensure the accuracy after turning. Summary of the Utility Model

[0004] To this end, the utility model provides a multi-operation structure valve casting, through a valve core operation assembly, to solve the problem that since the valve core is rotated for operation, it is easy to have a situation where the rotation is not in place when operating the valve core to turn, which in turn affects the flow direction of the media.

[0005] To achieve the above object, the utility model provides the following technical solution: A multi-operation structure valve casting, including a valve casting body, a valve top cover is fixedly provided at the top of the valve casting body, a sealing ring and a valve core rotation fixing ring are fixedly provided at the bottom of the valve top cover, a plurality of valve core rotation fixing holes are opened at the bottom of the valve core rotation fixing ring, a valve core operation assembly is arranged inside the valve casting body, the valve core operation assembly includes a valve core orientation operation ring, a square rod is fixedly provided at the bottom of the valve core orientation operation ring, a valve core rotation positioning ring is fixedly connected to the bottom of the square rod, a valve core rotation positioning column is fixedly provided at the top of the valve core rotation positioning ring, a valve core connection column is sleeved outside the square rod, a connection column through groove is opened inside the valve core connection column, a valve core body is fixedly provided at the bottom of the valve core connection column, a sealing block is sleeved outside the valve core body, and a spring is arranged between the valve core rotation positioning ring and the sealing block.

[0006] Preferably, a media flow direction mark is opened at the top of the valve core orientation operation ring, and the direction indicated by the media flow direction mark is the same as the direction indicated by the opening of the valve core body.

[0007] Preferably, the bottom of the square rod extends into the connection column through groove and is slidably connected to the connection column through groove.

[0008] Preferably, the valve core rotation positioning ring is sleeved outside the valve core connection column and is slidably connected to the valve core connection column. The valve core rotation positioning ring penetrates through the connection column through groove and is slidably connected to the connection column through groove.

[0009] Preferably, the top of the valve core rotation positioning column extends into the valve core rotation fixing hole and is slidably connected to the valve core rotation fixing hole.

[0010] Preferably, the valve core connection column penetrates through the valve top cover and is slidably connected to the valve top cover.

[0011] Preferably, the valve core body is arranged inside the valve casting body and is slidably connected to the valve casting body. The valve core body is arranged at the bottom of the sealing block and is slidably connected to the sealing block. The sealing block is arranged inside the valve casting body and is slidably connected to the valve casting body.

[0012] Preferably, the top of the spring is slidably connected to the bottom of the valve core rotation positioning ring, and the bottom of the spring is fixedly connected to the top of the sealing block.

[0013] The embodiments of the present utility model have the following advantages:

[0014] By pressing down the valve core towards the operation ring and rotating, the valve core moves downward towards the operation ring and drives the valve core rotation positioning ring to move downward through the square rod, so that the valve core rotation positioning column is pulled out from the valve core rotation fixing hole, releasing the restriction on the rotation of the valve core towards the operation ring. At the same time, the downward movement of the valve core rotation positioning ring causes the spring to contract. The rotation of the valve core towards the operation ring makes the valve core rotation positioning ring drive the valve core rotation positioning column to rotate through the square rod. At the same time, the rotation of the square rod drives the valve core body to rotate through the valve core connection column, so as to operate the orientation of the valve core body. By operating different orientations of the valve core body, the direction of the medium flow inside the valve casting body can be controlled, achieving the purpose of multi-operation of the medium flow direction;

[0015] After adjusting the orientation of the valve core body and then releasing the valve core towards the operation ring, the contracted spring pushes the valve core rotation positioning ring upward through the elastic force, so that the valve core rotation positioning column is inserted into the valve core rotation fixing hole. At this time, the valve core body rotates to the correct position. When the valve core rotation positioning column cannot be inserted into the valve core rotation fixing hole, the spring cannot push the valve core rotation positioning ring upward, and further the valve core towards the operation ring cannot be reset, which is convenient for the operator to observe and correct, preventing the medium inside the valve casting body from flowing into the unnecessary channels.

Specific Embodiments

[0024] The following specific embodiments illustrate the embodiments of the present utility model. Those who are familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0025] Refer to the attached Figure 1-Appendix Figure 5 A multi-operation structure valve casting provided by the present utility model includes a valve casting body 1. A valve top cover 2 is fixedly provided at the top of the valve casting body 1. A sealing ring 3 and a valve core rotation fixing ring 4 are fixedly provided at the bottom of the valve top cover 2. A plurality of valve core rotation fixing holes 5 are formed at the bottom of the valve core rotation fixing ring 4. A valve core operation assembly is arranged inside the valve casting body 1. The valve core operation assembly includes a valve core orientation operation ring 6. A square rod 8 is fixedly provided at the bottom of the valve core orientation operation ring 6. The bottom of the square rod 8 is fixedly connected to a valve core rotation positioning ring 9. A valve core rotation positioning column 10 is fixedly provided at the top of the valve core rotation positioning ring 9. A valve core connection column 11 is sleeved outside the square rod 8. A connection column through groove 12 is formed inside the valve core connection column 11. A valve core body 13 is fixedly provided at the bottom of the valve core connection column 11. A sealing block 15 is sleeved outside the valve core body 13. A spring 14 is arranged between the valve core rotation positioning ring 9 and the sealing block 15;

[0026] In this implementation scheme, in order to facilitate the operation of the valve core to turn in different directions and ensure the accuracy after turning, after the valve core body 13 is adjusted in orientation and the valve core orientation operation ring 6 is released, the contracted spring 14 pushes the valve core rotation positioning ring 9 upward through the elastic force, so that the valve core rotation positioning column 10 is inserted into the valve core rotation fixing hole 5. At this time, the valve core body 13 rotates to the correct position. When the valve core rotation positioning column 10 cannot be inserted into the valve core rotation fixing hole 5, the spring 14 cannot push the valve core rotation positioning ring 9 upward, and thus the valve core orientation operation ring 6 cannot be reset, which is convenient for the operator to observe and correct, and prevents the medium inside the valve casting body 1 from flowing into an unnecessary channel;

[0027] Among them, in order to achieve the purpose of facilitating the operation of the valve core body 13 to control the flow direction of the medium inside the valve casting body 1, the present device is implemented by the following technical solutions: A medium flow direction mark 7 is provided on the valve core facing the top of the operation ring 6, and the direction indicated by the medium flow direction mark 7 is the same as the direction indicated by the opening of the valve core body 13. The bottom of the square rod 8 extends into the connecting column through groove 12 and is slidably connected to the connecting column through groove 12. The valve core rotation positioning ring 9 is sleeved outside the valve core connecting column 11 and is slidably connected to the valve core connecting column 11. The valve core rotation positioning ring 9 penetrates through the connecting column through groove 12 and is slidably connected to the connecting column through groove 12. The top of the valve core rotation positioning column 10 extends into the valve core rotation fixing hole 5 and is slidably connected to the valve core rotation fixing hole 5. The valve core connecting column 11 penetrates through the valve top cover 2 and is slidably connected to the valve top cover 2. When the medium flow direction needs to be adjusted, press down the valve core towards the operation ring 6 and rotate it. When the valve core moves down towards the operation ring 6, it drives the valve core rotation positioning ring 9 to move downward through the square rod 8, so that the valve core rotation positioning column 10 is pulled out from the valve core rotation fixing hole 5, releasing the restriction on the rotation of the valve core towards the operation ring 6. At the same time, when the valve core rotation positioning ring 9 moves downward, the spring 14 contracts. When the valve core rotates towards the operation ring 6, it makes the valve core rotation positioning ring 9 drive the valve core rotation positioning column 10 to rotate through the square rod 8. At the same time, when the square rod 8 rotates, it drives the valve core body 13 to rotate through the valve core connecting column 11, thereby operating the orientation of the valve core body 13. By operating the valve core body 13 in different orientations, the flow direction of the medium inside the valve casting body 1 can be controlled, achieving the purpose of multi-operation of the medium flow direction;

[0028] Among them, in order to achieve the purpose of sealing the gap between the valve core body 13 and the valve casting body 1, the present device is implemented by the following technical solutions: The valve core body 13 is arranged inside the valve casting body 1 and is slidably connected to the valve casting body 1. The valve core body 13 is arranged at the bottom of the sealing block 15 and is slidably connected to the sealing block 15. The sealing block 15 is arranged inside the valve casting body 1 and is slidably connected to the valve casting body 1. The top of the spring 14 is slidably connected to the bottom of the valve core rotation positioning ring 9, and the bottom of the spring 14 is fixedly connected to the top of the sealing block 15. The gap between the valve core body 13 and the valve casting body 1 is sealed by the sealing block 15, so that the medium inside the valve casting body 1 can only flow into other channel interiors through the valve core body 13.

[0029] The use process of the utility model is as follows: when using the utility model, the valve casting body 1 is connected to multiple pipelines through multiple channel openings. When the flow direction of the medium needs to be adjusted, the valve core is pressed down toward the operating ring 6 and rotated. The valve core moves downward toward the operating ring 6 and drives the valve core rotation positioning ring 9 to move downward through the square rod 8, so that the valve core rotation positioning column 10 is withdrawn from the valve core rotation fixing hole 5, and the restriction on the rotation of the valve core toward the operating ring 6 is released. At the same time, the valve core rotation positioning ring 9 moves downward to cause the spring 14 to contract. The valve core rotates toward the operating ring 6 through the square rod 8, so that the valve core rotation positioning ring 9 drives the valve core rotation positioning column 10 to rotate, and at the same time, the square rod 8 rotates through the valve core connecting column 11 to drive the valve core body 13 to rotate, thereby operating the direction of the valve core body 13. By operating the valve core body 13 in different directions, the direction of medium flow inside the valve casting body 1 is controlled to achieve the purpose of multi-operation of medium flow direction. After the direction of the valve core body 13 is adjusted, the valve core is released toward the operating ring 6, and the contracted spring 14 pushes the valve core rotation positioning ring 9 upward through the elastic force, so that the valve core rotation positioning column 10 is inserted into the valve core rotation fixing hole 5. At this time, the valve core body 13 rotates to the correct position. When the valve core rotation positioning column 10 cannot be inserted into the valve core rotation fixing hole 5, the spring 14 cannot push the valve core rotation positioning ring 9 upward, and then the valve core toward the operating ring 6 cannot be reset, which is convenient for the operator to observe and correct, thereby preventing the medium inside the valve casting body 1 from flowing into unnecessary channels.

Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the above technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
