[0019] This part will describe the specific embodiments of the utility model in detail, and the preferred embodiments of the utility model are shown in the drawings, and the drawings are used to supplement the description of the text part, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the utility model, but it cannot be understood as the limitation of the protection scope of the utility model.

[0020] Reference Figure 1 , Figure 2 , and Figure 3 The utility model discloses an internal high-low difference stop valve body, which comprises a feed pipe 1, the filter plate 11 is detachably connected in the feed pipe 1, the spray port 2 is fixedly connected on the inner wall of the feed pipe 1, the blanking pipe 3 is arranged on the feed pipe 1, the valve body 19 is fixedly connected on the side surface of the feed pipe 1, the fixed plate 14 is fixedly connected in the valve body 19, the communication hole 20 is arranged on the fixed plate 14, the valve flap 13 is movably connected on the inner wall of the communication hole 20, the valve stem 17 is fixedly connected on the upper surface of the valve flap 13, the gasket 15 is fixedly connected on the upper surface of the valve body 19, the valve cover 8 is fixedly connected on the upper surface of the gasket 15, the valve cover cylinder 9 is fixedly connected on the valve cover 8, the valve stem 17 and the valve cover cylinder 9 are located on the same center, the discharge pipe 10 is fixedly connected on the side surface of the valve body 19, and the hand wheel 18 is fixedly connected on the upper surface of the valve stem 17. The valve cover cylinder 9 is communicated with the valve body 19, the valve stem 17 is screw-connected with the valve cover cylinder 9, the sealing ring 16 is fixedly connected on the inner wall of the valve cover cylinder 9, and the mounting hole 21 is arranged on the side surface of the feed pipe 1 and the discharge pipe 10.

[0021] Specifically, when the hand wheel 18 is in the closed position, the valve stem 17 drives the valve disc 13 to move downward, so that the valve disc 13 tightly fits the communication hole 20 on the fixed plate 14, thereby blocking the passage of fluid from the inlet pipe 1 to the outlet pipe 10. When the hand wheel 18 is counterclockwise, the valve stem 17 moves up and down in the valve cover cylinder 9 through threaded connection, driving the valve disc 13 to leave the communication hole 20, so that the fluid can flow from the inlet pipe 1 to the outlet pipe 10 through the communication hole 20. When the fluid enters the inlet pipe 1, it first passes through the filter plate 11, which can intercept impurities in the fluid to prevent impurities from entering the subsequent pipeline or equipment. When the device needs to be cleaned, the spray nozzle 2 is connected with the water tank 6, and the clean water in the water tank 6 is sprayed into the inlet pipe through the spray nozzle 2 to perform reverse flushing on the inside of the inlet pipe 1, removing the impurities intercepted by the filter plate 11. At the same time, the filter plate 11 can be disassembled and cleaned after a period of use.

[0022] The support frame 5 is fixedly connected to the outer surface of the inlet pipe 1, the bottom plate 7 is fixedly connected to the lower surface of the support frame 5, and the water tank 6 is fixedly connected to the upper surface of the bottom plate 7.

[0023] Specifically, the water tank 6 is fixed by the support frame 5 and the bottom plate 7, so that the input end of the spray nozzle 2 is connected with the water tank 6, ensuring the continuous supply of clean water during cleaning.

[0024] The knob 4 is fixedly connected to the outer surface of the blanking pipe 3, the piston 12 is movably connected to the inner wall of the blanking pipe 3, and the output end of the knob 4 is fixedly connected with the piston 12.

[0025] Specifically, the piston 12 is movably connected to the inner wall of the blanking pipe 3 and is controlled by the knob 4. When the knob 4 is turned, the piston 12 moves in the blanking pipe, thereby adjusting the on-off of the blanking pipe, so that the impurities and clean water after cleaning flow out of the device.

[0026] Working principle: when the hand wheel 18 is in the closed position, the valve stem 17 drives the valve 13 to move down, so that the valve 13 is closely attached to the communication hole 20 on the fixed plate 14, thereby blocking the passage of fluid from the inlet pipe 1 to the outlet pipe 10, when the hand wheel 18 is counterclockwise rotation, the valve stem 17 moves up and down in the valve cover cylinder 9 through the threaded connection, drives the valve 13 to leave the communication hole 20, the fluid can pass through the communication hole 20 from the inlet pipe 1 to the outlet pipe 10, when the fluid enters from the inlet pipe 1, it first passes through the filter plate 11, which can intercept the impurities in the fluid, preventing impurities from entering the subsequent pipeline or equipment, when the device needs to be cleaned, the spray nozzle 2 is connected with the water tank 6, the clean water in the water tank 6 is sprayed into the inside of the inlet pipe through the spray nozzle 2, and the inside of the inlet pipe 1 is reversely washed to remove the impurities intercepted by the filter plate 11, the piston 12 is movably connected to the inside wall of the drop pipe 3, and the piston is controlled through the knob 4. When the knob 4 is rotated, the piston 12 moves in the drop pipe, so as to adjust the on-off of the drop pipe, and make the impurities and clean water after cleaning flow out of the equipment.

[0027] The embodiments of the utility model are explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
