[0002] Valves are important control and regulation devices in industrial piping systems. During valve production and processing, valve spraying is of great significance. It can not only ensure that the valves are smooth and free of impurities and reduce mechanical losses, but the special coating can also increase the valves' corrosion resistance and rust resistance, thus extending the valves' service life.

[0022] according to Figure 1-5 As shown: the utility model provides a spraying device for the inside of a valve: it comprises a workbench 1, to which a spraying rack 2 is fixedly connected; a spraying box 4 is arranged on the spraying rack 2, to which a spraying pipe 3 is connected; a fixed box 5 is fixedly arranged inside the spraying rack 2, and two moving cylinders 6 are horizontally slidably arranged below the fixed box 5; a moving structure is slidably arranged inside the fixed box 5, and the moving structure is fixedly connected to the moving cylinder 6; a rotating column 17 is rotatably arranged inside the moving cylinder 6, and an internal nozzle 21 connected to the spraying pipe 3 is fixedly connected to the rotating column 17; an internal spray hole 20 is opened on the internal nozzle 21, and a card slot 18 corresponding to the two ends of the valve to be sprayed is opened on one side of the rotating column 17; an external spraying structure is arranged at the bottom of the fixed box 5.

[0023] The present application can insert the internal nozzle 21 into the valve when the valve is clamped and fixed, and can simultaneously seal both ends of the valve; this not only facilitates spraying inside the valve, but also avoids waste of spraying agent. At the same time, the present application also has the function of spraying the outside of the valve at the same time.

[0024] like Figure 3 As shown, the external spraying structure includes a support block 13 and an external spray head 14; the support block 13 is fixedly arranged below the fixed box 5, and the external spray head 14 is arranged at the bottom of the support block 13; a connecting pipe 12 connected to the external spray head 14 is arranged on the support block 13, and the connecting pipe 12 is connected to the external spraying equipment. By setting up the external spraying structure, it is convenient to spray the outside of the valve, thereby increasing practicality.

[0025] A collecting tank 15 is provided in the workbench 1 and is located directly below the external nozzle 14. A filter screen 16 corresponding to the collecting tank 15 is provided on the workbench 1. The filter screen 16 and the collecting tank 15 can filter and collect excess spraying agent generated by external spraying, thereby reducing the waste of spraying agent.

[0026] A rubber pad 19 is provided in the slot 18, which can greatly increase the friction between the rotating column 17 and the valve, so that when the rotating column 17 rotates, it can drive the valve to rotate, which is convenient for uniform spraying on the outside of the valve; an operating rod 22 is fixedly provided on one side of the rotating column 17, which is convenient for workers to manually operate the rotating column 17 to rotate.

[0027] like Figure 2 As shown, the moving structure includes a sliding block 10 and a connecting rod 11. The sliding block 10 is slidably arranged in the fixed box 5. A guide groove 8 is provided at the bottom of the fixed box 5. The connecting rod 11 is located in the guide groove 8 and is fixedly connected to the sliding block 10; the connecting rod 11 is fixedly connected to the moving cylinder 6. A motor 7 is provided on one side of the fixed box 5, and a bidirectional screw 9 rotatably arranged in the fixed box 5 is fixedly connected to the output shaft of the motor 7; two sliding blocks 10 are provided, and the two sliding blocks 10 are threadedly connected to the corresponding positions of the bidirectional screw 9; the setting of the guide groove 8 and the connecting rod 11 can limit the rotation of the sliding block 10, thereby converting the rotation of the bidirectional screw 9 into the movement of the sliding block 10, and driving the two moving cylinders 6 to move through the connecting rod 11.

[0028] like Figure 4 , 5 As shown, the internal spray hole 20 is arranged on the side of the internal nozzle 21, and the internal spray holes 20 are evenly distributed on the internal nozzle 21, which is convenient for comprehensive spraying of the inside of the valve; the internal nozzle 21 is a hard pipe, the spray pipe 3 is a soft pipe, and the spray pipe 3 is long enough to ensure the normal connection of the spray pipe 3 when the rotating column 17 rotates. At the same time, when the rotating column 17 rotates, it only rotates within a circle, reducing the entanglement of the spray pipe 3.

[0029] Principle of the utility model

[0030] like Figure 1-2 As shown, when using the present application, the valve to be sprayed is placed between the two moving cylinders 6 so that the two ends of the valve are aligned with the two internal nozzles 21. Start the motor 7, and driven by the two sliding blocks 10, the two moving cylinders 6 move in a direction close to each other until the two internal nozzles 21 are inserted into the interior of the valve. At the same time, the two ends of the valve are inserted into the slots 18. At this time, the valve is fixed. At the same time, the internal nozzle 21 is located inside the valve, which is convenient for spraying the inside of the valve. The cooperation of the other two rotating columns 17 and the slots 18 also closes the two ends of the valve. When the spray box 4 and the spray pipe 3 are used to transport the spray agent to the internal nozzle 21, the spray agent is sprayed from the internal spray hole 20 to spray the inside of the valve, and the spray agent basically does not escape from the valve, reducing the waste of the spray agent.

[0031] like Figure 3As shown, the present application can also spray the outside of the valve at the same time; the connecting pipe 12 is connected to the external spraying equipment, and the external spraying equipment is started to spray the outside of the valve. At the same time, the operating lever 22 can be manually operated to make the rotating column 17 start to rotate. Due to the setting of the rubber pad 19, the rotating column 17 can drive the valve to rotate when driven by friction, thereby facilitating uniform spraying of the outer surface of the valve; excess spraying agent sprayed on the outside of the valve can enter the collecting tank 15 through the filter screen 16 to avoid waste of spraying agent.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
