Description

Technical Field

[0001] This utility model relates to the field of plug valve processing technology, and in particular to a plug valve painting fixture. Background Technology

[0002] A plug valve is a rotary valve with a shut-off element or plunger. It is opened or closed by rotating the plug 90 degrees to open or close the passage on the plug with the passage on the valve body. The plug can be cylindrical or conical. In cylindrical plugs, the passage is generally rectangular; in conical plugs, the passage is trapezoidal. These shapes make plug valves lightweight. They are best suited for cutting off and connecting media, as well as for diverting flow; however, depending on the application and the erosion resistance of the sealing surface, they can sometimes be used for throttling. During the production of plug valves, it is usually necessary to use painting tools to paint the surface of the plug valve to prevent rusting.

[0003] However, existing plug valves have flange structures at both ends and are shaped like dumbbells. Traditional V-blocks or simple chucks can only clamp the outer circle and cannot restrict circumferential rotation. During spraying, deflection is likely to occur, resulting in localized drips or missed spraying. Therefore, a plug valve painting fixture is proposed to solve the above problems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a plug valve painting fixture, which includes a base frame 1 and a rotating mechanism 2 provided on the upper surface of the base frame 1. The rotating mechanism 2 can clamp and rotate the plug valve, thereby facilitating the painting of the plug valve.

[0027] The rotating mechanism 2 includes a movable seat 201 and a fixed seat 202. The inner wall of the movable seat 201 is rotatably connected to a rotating shaft 203 via a bearing. The right end of the rotating shaft 203 is fixedly connected to a first clamping plate 204. The inner wall of the first clamping plate 204 is rotatably connected to a bidirectional screw 209 via a bearing. The outer wall of the bidirectional screw 209 is threadedly connected to an adjusting seat 210. The adjusting seat 210 is connected to a pull rod 211. The pull rod 211 is connected to a positioning seat 212. Rotating the bidirectional screw 209 can move the adjusting seat 210. The position of the positioning seat 212 can be adjusted by the pull rod 211. The positioning seat 212 can be inserted into the flange mounting hole of the plug valve port to position the plug valve and prevent the plug valve from falling off during rotation.

[0028] A motor 207 is fixedly connected to the side wall of the fixed base 202. A second clamping plate 208 is fixedly connected to the output end of the motor 207. Starting the motor 207 can drive the second clamping plate 208 to rotate, which, together with the first clamping plate 204, clamps and rotates the plug valve.

[0029] A fixed frame 205 is fixedly connected to the upper surface of the base frame 1. A hydraulic cylinder 206 is fixedly connected to the inner wall of the fixed frame 205. The left wall of the movable seat 201 is fixedly connected to the telescopic end of the hydraulic cylinder 206. The fixed seat 202 is fixedly connected to the upper surface of the base frame 1. By activating the hydraulic cylinder 206, the movable seat 201 can be moved, thereby adjusting the position of the first clamping plate 204 so that the first clamping plate 204 presses against the port of the plug valve, and cooperates with the second clamping plate 208 to clamp and fix the plug valve.

[0030] One end of the pull rod 211 is hinged to the outer wall of the adjusting seat 210 by a pin, and the other end of the pull rod 211 is hinged to the bottom of the positioning seat 212 by a pin. The upper end of the bidirectional screw 209 is fixedly connected to a knob 214, which allows the user to easily rotate the bidirectional screw 209.

[0031] The inner wall of the first clamping plate 204 is fixedly connected to a guide rod 213, and the inner wall of the positioning seat 212 is slidably connected to the outer wall of the guide rod 213. The guide rod 213 can limit and guide the positioning seat 212, making the positioning seat 212 more stable when moving.

[0032] Reference Figure 1 , Figure 4 A cover plate 215 is fixedly connected to the left wall of the first clamping plate 204. A guide opening 216 is provided on the side of the cover plate 215. The outer wall of the positioning seat 212 is slidably connected to the inner wall of the guide opening 216. The positioning seat 212 can easily pass through the cover plate 215 through the guide opening 216.

[0033] The inner wall of the base frame 1 is provided with a sliding groove 4, and a sliding seat 5 is slidably connected to the inner wall of the sliding groove 4. The top of the sliding seat 5 is fixedly connected to the bottom of the movable seat 201. The sliding groove 4 and the sliding seat 5 can play a role in limiting and guiding the movable seat 201.

[0034] Reference Figure 1 , Figure 5 A blower mechanism 3 is provided on the upper surface of the base frame 1. The blower mechanism 3 includes a pipe seat 301, which is fixedly connected to the upper surface of the base frame 1. An air duct 302 is fixedly connected to the inner wall of the pipe seat 301. A blower hood 303 is fixedly connected to the upper end of the air duct 302, and a connecting pipe 304 is fixedly connected to the lower end of the air duct 302. A hot air blower is connected to the connecting pipe 304, which allows the blower hood 303 to dry the surface paint layer of the stopcock valve, thereby improving the curing efficiency of the stopcock valve paint.

[0035] Working principle: When the plug valve needs to be clamped, the user can turn the knob 214 to drive the bidirectional screw 209 to rotate, causing the adjusting seat 210 to move. The movement of the adjusting seat 210 will drive the positioning seat 212 to adjust its position through the pull rod 211. After the two positioning seats 212 are adjusted, the flange mounting hole of the plug valve port can be aligned with the positioning seat 212, so that the positioning seat 212 is inserted into the flange mounting hole to achieve the positioning of the plug valve. Then, the hydraulic cylinder 206 is started to clamp and fix the plug valve with its two clamping discs. Then, the motor 207 is started to make the plug valve rotate. Then, the rotating plug valve is painted with paint by the painting equipment. After the painting is completed, the external hot air blower delivers hot air to the air duct 302 through the connecting pipe 304. The hot air is blown onto the rotating valve body through the blower hood 303, so that the paint layer on the surface of the valve body is quickly cured.

[0036] It is worth noting that in this embodiment, the electrical equipment is a common device in the prior art, and the model used can be customized according to actual usage requirements. The power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and a wire (not shown in the figure) to realize its control.
