Description

Technical Field

[0001] This utility model relates to the field of ball valve processing technology, specifically to a thermal spraying device for valve balls. Background Technology

[0002] As the core sealing component of a ball valve, the surface properties of the valve ball directly determine the valve's sealing reliability, corrosion resistance, and service life. In harsh working conditions such as petroleum, chemical, and natural gas industries, the valve ball must withstand high pressure, high temperature, and strong media erosion. Therefore, it is necessary to prepare a wear-resistant and corrosion-resistant coating on its surface using thermal spraying technology to improve surface hardness and corrosion resistance.

[0003] Existing thermal spraying equipment often uses fixed spray guns or allows only rough position adjustments, making it difficult to precisely adjust the spraying distance according to changes in the diameter of the valve ball. When processing balls of different sizes, uneven coating thickness often results from improper distance. Small-diameter balls are prone to localized overspraying, while large-diameter balls may have spraying blind spots, severely affecting the consistency and integrity of the coating quality. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a thermal spraying device for valve balls, which solves the problem mentioned in the background art that the spray guns of existing thermal spraying devices are mostly fixed or can only be roughly adjusted, making it difficult to accurately adjust the spraying distance according to the diameter changes of the valve ball.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thermal spraying device for a valve ball, comprising a housing, an arc-shaped frame fixedly connected to the top inner side of the housing, a slider slidably connected to the surface of the arc-shaped frame, a side block fixedly connected to the side wall of the slider, a spray pipe penetrating the surface of the side block, the spray pipe being slidably connected to the side block, and a rotating seat rotatably connected to the center of the bottom inner side of the housing.

[0006] In this technical solution, an arc-shaped frame is set inside the box. The nozzle on the side block surface of the slider sidewall can be pulled to adjust the distance between its spraying end and the ball. This allows for free adjustment of the spraying distance when processing balls of different sizes. By adjusting the spraying distance, the problem of uneven coating thickness caused by unsuitable distance is effectively avoided, and the uniformity and coverage of the coating are significantly improved.

[0007] Preferably, a bidirectional lead screw is rotatably connected between the inner sidewalls of the rotating seat. One end of the bidirectional lead screw penetrates the outer surface of the rotating seat, and two threaded sleeves penetrate the surface of the bidirectional lead screw and are threadedly connected to the threaded sleeves. A support frame is fixedly connected to the top end of the threaded sleeves, and a stop block is fixedly connected to the top end of the support frame.

[0008] Preferably, a servo motor is fixedly connected to the center of the bottom of the housing, and the tail end of the drive shaft of the servo motor is connected to the rotating seat via a coupling.

[0009] Preferably, the outer wall of the slider is threaded with a No. 1 extrusion bolt, and the outer wall of the side block is threaded with a No. 2 extrusion bolt.

[0010] Preferably, the top of the box is provided with a paint tank, the liquid pump opening of the paint tank is connected to the upper end of the extraction pipe, the lower end of the extraction pipe passes through the side wall of the box and is connected to the distribution pipe, and the surface of the distribution pipe is provided with several interfaces carrying manual valves.

[0011] Preferably, a flexible hose is fixedly connected to one end of the nozzle facing the distribution pipe, the other end of the flexible hose is sealed to the interface, and both ends of the flexible hose are respectively connected to the nozzle and the distribution pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting an arc-shaped frame inside the housing, allows the spray nozzle on the side block surface of the slider sidewall to adjust the distance between its spraying end and the ball by pulling, thereby enabling free adjustment of the spraying distance when processing balls of different sizes. By adjusting the spraying distance, the problem of uneven coating thickness caused by unsuitable distance is effectively avoided, and the uniformity and coverage of the coating are significantly improved.

[0014] 2. This utility model achieves multi-gun coordinated spraying by setting up a material distribution pipe with multiple interfaces and combining multiple sets of sliders and spray nozzles that can be flexibly arranged on an arc frame. It can not only flexibly increase or decrease the number of spray nozzles according to processing needs, but also improve spraying efficiency through synchronous operation of multiple guns, greatly enhance the adaptability of the equipment to different working conditions, and improve the ease of operation and versatility of the equipment.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A thermal spraying device for valve balls, see [link / reference] Figures 1 to 4 The device includes a housing 1, an arc-shaped frame 5 fixedly connected to the top inner side of the housing 1, a slider 6 slidably connected to the surface of the arc-shaped frame 5, a side block 7 fixedly connected to the side wall of the slider 6, a nozzle 8 penetrating the surface of the side block 7, the nozzle 8 slidably connected to the side block 7, a first extrusion bolt 61 threadedly connected to the outer side wall of the slider 6, and a second extrusion bolt 701 threadedly connected to the outer side wall of the side block 7.

[0023] In the above technical solution, the position of the spray nozzle 8 can be adjusted by pushing the slider 6 to slide along the arc frame 5, and the axial spraying distance can be changed by pulling the spray nozzle 8 to slide along the side block 7. After adjustment, tighten the first extrusion bolt 61 and the second extrusion bolt 701 to achieve rigid fixation. When processing spheres of different sizes, the spraying distance can be freely adjusted. By adjusting the spraying distance, the problem of uneven coating thickness caused by unsuitable distance is effectively avoided, and the uniformity and coverage integrity of the coating are significantly improved.

[0024] Specifically, such as Figure 4 As shown, the top of the housing 1 is equipped with a paint tank 14. The paint tank 14 has the ability to heat. An electric heating wire can be installed in the inner wall of the paint tank 14. After being powered on, the paint can be heated directly. This is an existing mature technology, so the specific structure and working principle will not be described in detail. The opening of the liquid pump 13 of the paint tank 14 is connected to the upper end of the extraction pipe 12. The lower end of the extraction pipe 12 passes through the side wall of the housing 1 and is connected to the distribution pipe 10. The surface of the distribution pipe 10 is provided with several interfaces 11 carrying manual valves. The liquid pump 13 transports the spraying material in the paint tank 14 to the distribution pipe 10 through the extraction pipe 12. By controlling the manual valve of the interface 11, the material can be selectively supplied to different spray nozzles 8. The design of multiple interfaces 11 supports the simultaneous connection of multiple spray nozzles 8. With the independent control of the manual valve, it can achieve precise operation of a single nozzle and improve efficiency by coordinating multiple nozzles, thus enhancing the flexibility of equipment layout.

[0025] Furthermore, such as Figure 4As shown, a hose 9 is fixedly connected to one end of the nozzle 8 facing the distribution pipe 10. The other end of the hose 9 is sealed to the interface 11. Both ends of the hose 9 are connected to the nozzle 8 and the distribution pipe 10 respectively. The connection method of the hose 9 makes it convenient to adjust the position of the nozzle 8 at any time, which enhances the flexibility of the equipment layout.

[0026] It is worth noting that, such as Figure 2 and Figure 3 As shown, a rotating seat 3 is rotatably connected to the center of the bottom inner side of the housing 1. A bidirectional lead screw 4 is rotatably connected between the inner walls of the rotating seat 3. One end of the bidirectional lead screw 4 passes through the outer surface of the rotating seat 3. Two threaded sleeves 401 pass through the surface of the bidirectional lead screw 4 and are threadedly connected to the threaded sleeves 401. A support frame 402 is fixedly connected to the top of the threaded sleeves 401. A stop block 403 is fixedly connected to the top of the support frame 402. The surface of the stop block 403 is provided with an anti-slip coating to increase friction. A servo motor 2 is fixedly connected to the center of the bottom of the housing 1. The tail end of the drive shaft of the servo motor 2 is connected to the rotating seat 3 through a coupling. Rotating the bidirectional lead screw 4 can drive the two threaded sleeves 401 to move synchronously in opposite directions, thereby driving the support frame 402 and the stop block 403 to adjust the distance, so as to abut valve balls of different diameters through the hole in the center of the ball. The servo motor 2 drives the rotating seat 3 to rotate, so that the ball rotates slowly and uniformly to cooperate with the spray nozzle 8 to complete the full surface spraying.

[0027] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
