Description

Technical Field

[0001] The utility model relates to the field of feed valves, in particular to a wear-resistant ceramic rotary feed valve. Background Art

[0002] Feed valve, as the name implies, is a valve used to control and adjust the feed flow and pressure of materials. In industrial production, feed valves are generally widely used in systems for conveying, pumping and storing various liquid, gaseous and solid substances.

[0003] The existing feed valve is sealed and transmitted by means of a simple electrically controlled butterfly valve or gate valve. However, the butterfly valve requires a large amount of kinetic energy when opening and closing, and the opening and closing efficiency of the ordinary gate valve is too slow, resulting in excessive impact force at the opening and closing point, causing damage to the seal. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the butterfly valve requires relatively large kinetic energy when opening and closing, and the opening and closing efficiency of the common gate valve is too slow, resulting in excessive impact force on the opening and closing part, causing damage to the sealing part.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: providing a wear-resistant ceramic rotary feed valve, including a valve body, an adjusting chamber is opened inside the valve body, a rotating shaft is rotatably connected inside the adjusting chamber, a fine-tuning nut is engaged at one end of the rotating shaft, a rocker is fixedly connected at one end of the rotating shaft close to the fine-tuning nut, a pushing sleeve is fixedly connected at one end of the rocker away from the rotating shaft, a valve core is arranged at one end of the pushing sleeve away from the rocker, an upper flange is fixedly connected to one side of the valve body, the valve core abuts against one side of the upper flange, a driving rod is engaged at one end of the rotating shaft away from the fine-tuning nut, and a fixing rod is engaged at the outside of the driving rod.

[0006] The above technical solution achieves the effect of driving the rotating shaft to drive the rocker arm through the fixed rod to make the valve core open and close in a fan shape, solves the problem of excessive pressure of butterfly valves and low opening and closing rate of gate valves in the past, and improves the wear resistance of the equipment.

[0007] The utility model is further configured that an adjusting groove is opened on one side of the valve core close to the pushing sleeve, a push block is abutted inside the adjusting groove, an end of the push block away from the adjusting groove is fixedly connected to a spring, an end of the spring away from the push block is fixedly connected to a bottom push block, and the bottom push block is fixedly connected inside the pushing sleeve.

[0008] The utility model is further configured that a fine-tuning hole is provided on the side of the valve body away from the upper flange, the fine-tuning hole is provided at a position of the valve body close to a fine-tuning nut, and the fine-tuning hole is communicated with the interior of the adjustment chamber.

[0009] The utility model is further configured that the fixing rod is rotatably connected to one end away from the driving rod with a supporting shaft, the supporting shaft is externally rotatably connected to a pushing block, and the pushing block abuts against one side of the fixing rod.

[0010] Through the above technical solution, the fine-tuning hole can be used to adjust the fine-tuning nut, thereby controlling the fitting strength between the valve core and the upper flange. This solves the problem of large wear and slow opening and closing speed caused by the previous use of a fixed structure for opening and closing, and improves the adjustability of the valve core.

[0011] The utility model is further configured that the outer thread of the support shaft is connected with a threaded sleeve, the threaded sleeve abuts against one side of the pushing block, and a pushing component is arranged on one side of the pushing block.

[0012] The utility model is further configured that the pushing assembly includes a telescopic rod, the telescopic rod is fixedly connected to a side of the pushing block away from the fixed rod, and a cylinder is arranged on the side of the telescopic rod away from the pushing block.

[0013] The utility model is further configured that a connecting rod is threadedly connected to one side of the cylinder close to the valve body, one end of the connecting rod is fixedly connected to the outside of the upper flange, and the connecting rod is configured in a rectangular shape.

[0014] The utility model is further configured that a lower flange is fixedly connected to the bottom of the valve body, the lower flange is communicated with the inside of the rotating shaft, and the lower flange is open near a side of the regulating chamber.

[0015] The above technical solution achieves the effect that after the valve is opened, the upper flange will conduct the material to be transmitted along the lower flange, solving the problem that part of the material enters the regulating bin due to the same outer diameter of the lower flange and the upper flange, thereby improving the stability of transmission.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model can start the cylinder when in use, so that the telescopic rod pushes the fixed rod to drive the rotating shaft to rotate, so that the rocker arm rotates along the inside of the adjusting bin to move the valve core away from the upper flange side, so that the upper flange can be transmitted. When the transmitted material is different, the position of the rocker arm can be adjusted by the fine-tuning nut through the fine-tuning hole, so that the fitting strength of the valve core and the upper flange can be adjusted, which solves the problem that the valve core wears too quickly due to the same tightness of the valve core when transmitting any material due to the fixed structure used in the past, and improves the wear resistance of the valve core.

During operation, the upper flange 11 can be fixed to the port for transmitting materials when transmission is required. When transmission is required, it is only necessary to let the fixing rod 13 push the driving rod 12 to rotate, so that the driving rod 12 drives the rotating shaft 2 to rotate and drives the rocker 4 to rotate. When the rocker 4 rotates, the valve core 9 can be pushed away from the bottom of the upper flange 11, so as to achieve the effect of opening the upper flange 11.

When different materials need to be transmitted, the adjustment tool can be inserted along the fine-tuning hole 21, and then the fine-tuning nut 3 is adjusted to control the height of the rocker 4, and the extrusion force of the spring 7 controls the pressure between the valve core 9 and the upper flange 11, so that the transmission of different materials is achieved. When the transmission is completed, the valve core 9 can be reset to the bottom of the upper flange 11 by simply rotating in the opposite direction. In this way, the valve core 9 is reset to seal and block, and the entire opening and closing process is realized. When it is necessary to push or pull the fine-tuning nut 3, it is only necessary to start the cylinder 18 to allow the telescopic rod 17 to control the fixed rod 13 to move forward and backward. The cylinder 18 is fixed by the connecting rod 19, which can better combine the cylinder 18 with the valve body 1 to achieve the effect of opening and closing the valve body 1. When the material is transmitted, the material enters along the upper flange 11 and continues to be transmitted along the opening of the lower flange 22, so that the conduction effect is achieved. When closing, part of the material will drip along the gap.
