Technical Field
[0001] This utility model relates to the technical field of valve production equipment, specifically a surface spraying equipment for the production of special valves. Background Technology
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. They can be divided into shut-off valves, check valves, regulating valves, etc. Their structures can be divided into butterfly valves and ball valves. Special valves require coating. In the existing technology, when spraying valves with a spraying pipe, the outer surface of the valve is wrapped by a limiting component, which prevents some surfaces from being coated in place. The coating effect on the surface of the parts is poor, requiring multiple adjustments, and it cannot play a role in fixing the valve from the inside.
[0003] For example, the authorized patent document with application number CN202322596618.6 discloses a multi-functional spraying device for valve processing, including a worktable, a fixing component, and a spraying component. The fixing component is movably installed on the top of the worktable, and the spraying component is fixedly installed above the fixing component. Different types of valves are stably fixed by the fixing component, and the fixed valves are sprayed by the spraying component. It is suitable for use with various types of valves. The fixing component includes a moving plate, a first fixed seat, a second fixed seat, a pressure plate, a rotating rod, a rotating handle, and a rotating motor. The moving plate is movably installed on the top of the worktable. This utility model can fix different types of valves, avoiding the need to change different equipment when processing valves, greatly improving the efficiency of valve processing. Moreover, when the spray gun is moved up and down by the telescopic cylinder, it is convenient to spray different positions.
[0004] The aforementioned patent has the problem that the outer surface of the valve is covered by a limiting component, which prevents some surfaces from being coated properly. Therefore, we need to provide a special surface spraying equipment for valve production. Utility Model Content
[0005] The purpose of this invention is to provide a surface coating equipment for the production of special valves. The special valves to be coated are placed on top of a tray. The bottom groove of the valve is located at the top of two limiting rods. A motor drives a threaded rod to rotate, which in turn moves a surface drive ring. The drive ring pushes two push rods, causing the tops of the two limiting rods to move away from each other, thus supporting and limiting the valve's internal groove and preventing obstruction of the valve's outer surface. A pump is activated to draw coating liquid from the tank into the main pipe. The coating liquid is then sprayed out through nozzles on the main and auxiliary pipes to coat the valve surface. Simultaneously, a rotating chassis drives a ring-shaped guide rail to rotate on top of several columns. Ball bearings are mounted on the rotating tops of these columns, and these ball bearings rotate at the grooves at the bottom of the ring-shaped guide rail. Annular grooves are also provided on the surface of the limiting rods to limit the chassis rotation, preventing excessive rotation from affecting the motor. Depending on the valve's length, a cylinder can be activated to adjust the height of the lifting plate, thus solving the problems mentioned in the background art.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a surface spraying equipment for the production of special valves, comprising:
[0026] Frame 1;
[0027] and a coating component 2 installed on the top of the frame 1 for spraying the valve surface;
[0028] Limiting element 3 installed inside the frame 1 for fixing the valve;
[0029] The limiting component 3 includes a chassis 31 disposed within the frame 1. A threaded rod 32 is rotatably mounted inside the chassis 31. A motor 33 is mounted at the lower end of the threaded rod 32. A drive ring 34 is threaded onto the surface of the threaded rod 32. Push rods 35 are hinged to both sides of the drive ring 34. Limiting rods 36 are hinged to the opposite ends of the two push rods 35. The bottoms of the two limiting rods 36 are hinged to the top of the chassis 31.
[0030] A tray 4 is fixedly installed on the top of the chassis 31 by several rods. The inside of the tray 4 is provided with a reserved slot 5 for the movement of two limit rods 36.
[0031] In this embodiment, the special valve to be sprayed is placed on top of the tray 4, with the bottom groove of the valve located at the top of the two limiting rods 36. The starting motor 33 drives the threaded rod 32 to rotate, which in turn moves the surface drive ring 34. The drive ring 34 pushes the two push rods 35 to move the tops of the two limiting rods 36 away from each other, thus supporting and limiting the valve's interior groove and preventing obstruction of the valve's outer surface. The pump body 113 is started to draw the coating liquid from the housing 111 into the main pipe 112. The coating liquid then passes through the main pipe 112 and the auxiliary pipe 12. The spray nozzles spray onto the surface of the valve, while the rotating chassis 31 drives the annular guide rail 10 to rotate on top of several columns 8. The top of each column 8 is equipped with ball bearings 9, which rotate in the grooves at the bottom of the annular guide rail 10. An annular groove 13 is provided on the surface of the limiting rod 36 to limit the rotation of the chassis 31 and prevent excessive rotation of the chassis from affecting the motor 33. Depending on the length of the valve, the cylinder 6 can be activated to adjust the height of the lifting plate 7. The two cylinders 6 are synchronous cylinders.
[0032] Two cylinders 6 are embedded in the bottom of the frame 1, and a lifting plate 7 is fixedly installed on the upper end of the two cylinders 6.
[0033] Specifically, depending on the length of the valve, the cylinder 6 can be activated to drive the lifting plate 7 to adjust its height, wherein the two cylinders 6 are synchronous cylinders 6.
[0034] The top of the lifting plate 7 is fixedly installed with several columns 8, and the top of each column 8 is rotatably installed with ball bearings 9. The bottom of the chassis 31 is fixedly installed with an annular guide rail 10 that works in conjunction with the ball bearings 9.
[0035] It is worth noting that a ball bearing 9 is rotatably mounted on the top of the column 8, and several balls bearing 9 rotate in the groove at the bottom of the annular guide rail 10, which reduces the friction on the rotation of the chassis 31.
[0036] It also includes a spraying component 11 for valve painting. The spraying component 11 includes a box 111 fixedly installed on the top of the frame 1. One side of the box 111 is connected to a main pipe 112 through a pipe, and the inside of the pipe is connected to a pump body 113.
[0037] Furthermore, the pump body 113 is started to draw the coating liquid from the housing 111 into the main pipe 112, and the coating liquid is sprayed out through the nozzles on the surface of the main pipe 112 and the secondary pipe 12 to coat the valve surface.
[0038] Both sides of the main pipe 112 are connected to the secondary pipes 12, and the bottom of the main pipe 112 and the surfaces of the two secondary pipes 12 are connected to the nozzles.
[0039] In this process, the spraying liquid is sprayed out through the nozzles on the surface of the main pipe 112 and the secondary pipe 12, and the secondary pipes 12 distributed on both sides spray the surface of the valve vehicle.
[0040] The surface of the chassis 31 is provided with an annular groove 13, and the interior of the annular groove 13 is movable and adjustable with a limit post 14. The bottom of the limit post 14 is fixedly installed on the top of the lifting plate 7.
[0041] Specifically, an annular groove 13 is set on the surface of the limiting post 14 to limit the rotation of the chassis 31 and prevent the excessive rotation of the chassis from affecting the motor 33.
[0042] This device places the special valves to be sprayed on top of the tray 4. The bottom groove of the valve is located at the top of the two limiting rods 36. The motor 33 drives the threaded rod 32 to rotate, which in turn drives the surface driving ring 34 to move. The driving ring 34 pushes the two push rods 35 to move the tops of the two limiting rods 36 away from each other, supporting and limiting the valve's internal groove to prevent obstruction of the valve's outer surface. The pump body 113 is started to draw the coating liquid from the housing 111 into the main pipe 112. The coating liquid is sprayed out through the nozzles on the surface of the main pipe 112 and the secondary pipe 12 to coat the valve surface. At the same time, the base 31 can be rotated to drive the annular guide rail 10 to rotate on top of several columns 8. The top of the columns 8 is equipped with ball bearings 9, which rotate in the groove at the bottom of the annular guide rail 10. An annular groove 13 is set on the surface of the limiting column 14 to limit the rotation of the base 31 and prevent excessive rotation of the base from affecting the motor 33. Depending on the length of the valve, the cylinder 6 can be started to adjust the height of the lifting plate 7.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
