Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a gate valve overall surface anti-corrosion treatment device. Background Technology

[0002] Gate valves are a commonly used type of valve, playing a crucial role in fluid transport systems across numerous industrial and civil applications. Their basic structure consists mainly of a valve body, valve seat, valve disc, valve stem, stuffing box, and handwheel. The valve body is the outer shell of the gate valve, providing structural support for the entire valve. It is typically made of metals such as cast iron, cast steel, or stainless steel, and has internal channels for fluid passage. The valve seat is generally installed on the valve body channel, forming a sealing surface with the valve disc. It is usually made of metals such as copper alloys or non-metals such as polytetrafluoroethylene (PTFE), capable of withstanding fluid pressure and ensuring a good sealing effect.

[0003] Regarding the above technical solutions, existing anti-corrosion treatment devices do not have a good auxiliary shaking function. After the shut-off valve enters the paint tank, air bubbles are easily left on the surface. These air bubbles will affect the performance of the anti-corrosion coating and do not have a good guarantee of the flowability of the anti-corrosion paint, which will affect the quality of the anti-corrosion paint and thus the effectiveness of the anti-corrosion treatment.

[0004] Therefore, this utility model provides an anti-corrosion treatment device for the overall surface of a stop valve to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an overall surface anti-corrosion treatment device for gate valves, which solves the problem that the existing anti-corrosion treatment devices do not have a good auxiliary shaking function, and that air bubbles are easily left on the surface of the gate valve after it enters the paint box, which affects the performance of the anti-corrosion coating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for overall surface anti-corrosion treatment of a gate valve, comprising a base plate, a fixed frame fixedly installed on the top of the base plate, a lifting assembly fixedly installed on the top of the fixed frame, a clamping assembly fixedly connected to the bottom of the lifting assembly, an anti-corrosion paint box provided on the top of the base plate, and a protective assembly provided on the top of the anti-corrosion paint box; the lifting assembly comprises a slide rod and a spring, the slide rod being slidably connected to the top of the fixed frame, the spring being sleeved on the side wall of the slide rod, a fixed pulley fixedly connected to the top of the slide rod, a connecting frame fixedly installed on the top of the fixed frame, a motor fixedly installed on one side of the connecting frame, a cam fixedly connected to the output end of the motor, a first lifting frame fixedly connected to the bottom end of the slide rod, and an electric push rod fixedly installed on the inner side wall of the first lifting frame.

[0007] Furthermore, the clamping assembly includes a second lifting frame and a bidirectional threaded rod. The second lifting frame is fixedly connected to the output end of the electric push rod. The bidirectional threaded rod is connected to the inner side wall of the second lifting frame via a bearing. A clamping plate is threadedly connected to the side wall of the bidirectional threaded rod, and the clamping plate is slidably connected to the second lifting frame.

[0008] The above technical solution can be used to clamp the valve body.

[0009] Furthermore, the clamping assembly also includes a knob, which is fixedly connected to one end of the bidirectional threaded rod.

[0010] The above technical solution allows for convenient rotation of the bidirectional threaded rod using a knob.

[0011] Furthermore, a shut-off valve body is provided on one side of the clamping plate, and the shut-off valve body is located in the middle of the clamping plate.

[0012] The above technical solution can achieve a good clamping effect.

[0013] Furthermore, the protective component includes a protective plate disposed on top of the anti-corrosion paint tank.

[0014] The above technical solution can achieve a good anti-corrosion effect on the anti-corrosion paint box.

[0015] Furthermore, the protective assembly also includes a sliding plate and a sliding groove. The sliding plate is fixedly installed on the bottom of the protective plate, and the sliding groove is formed on the top of the base plate. The sliding plate and the sliding groove are slidably connected.

[0016] The above technical solution makes it easier to move the protective panel.

[0017] Furthermore, the protective assembly also includes an iron plate and a magnet. The iron plate is fixedly installed at the bottom of the protective plate, and the magnet is fixedly installed on one side of the anti-corrosion paint box. The iron plate and the magnet are magnetically connected.

[0018] The above technical solution can achieve a very good protective effect.

[0019] Beneficial effects

[0020] This invention provides a device for integral surface anti-corrosion treatment of a gate valve. Compared with the prior art, it has the following advantages:

[0021] 1. The overall surface anti-corrosion treatment device for this gate valve, through the setting of lifting components, can immerse the gate valve body in anti-corrosion paint and shake the gate valve body to prevent residual air bubbles on its surface. This allows the gate valve surface to form a uniform, dense, and flawless anti-corrosion paint coating. This not only greatly improves the anti-corrosion effect and effectively isolates the gate valve metal from external corrosive media, extending the service life of the gate valve, but also makes the appearance more beautiful and smooth. In subsequent installation and use, it also reduces problems such as local corrosion and peeling caused by coating defects, ensuring the reliable operation of the gate valve in various fluid transportation systems and reducing maintenance costs and replacement frequency caused by corrosion-induced failures.

[0022] 2. The overall surface anti-corrosion treatment device for the gate valve, through its protective components, can protect the anti-corrosion paint tank, preventing the anti-corrosion paint inside from losing its fluidity. This ensures that the anti-corrosion paint always maintains a suitable working state, guaranteeing an ideal coating effect every time the gate valve is immersed. At the same time, it avoids the need for frequent paint replacements due to changes in paint fluidity, saving raw material costs and ensuring the continuity and efficiency of the entire anti-corrosion treatment process.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1 to 4 This application provides an overall surface anti-corrosion treatment device for a gate valve, including a base plate 1, a fixed frame 2 fixedly installed on the top of the base plate 1, a lifting assembly 3 fixedly installed on the top of the fixed frame 2, a clamping assembly 4 fixedly connected to the bottom of the lifting assembly 3, an anti-corrosion paint box 6 provided on the top of the base plate 1, and a protective assembly 7 provided on the top of the anti-corrosion paint box 6; the lifting assembly 3 includes a slide rod 31 and a spring 32, the slide rod 31 is slidably connected to the top of the fixed frame 2, the spring 32 is sleeved on the side wall of the slide rod 31, a fixed pulley 33 is fixedly connected to the top of the slide rod 31, a connecting frame 34 is fixedly installed on the top of the fixed frame 2, a motor 35 is fixedly installed on one side of the connecting frame 34, a cam 36 is fixedly connected to the output end of the motor 35, a lifting frame 37 is fixedly connected to the bottom end of the slide rod 31, and an electric push rod 38 is fixedly installed on the inner side wall of the lifting frame 37.

[0032] In this embodiment, the motor 35 drives the cam 36 to rotate. During the rotation of the cam 36, it periodically squeezes the fixed pulley 33 at the top of the slide rod 31, forcing the slide rod 31 to slide downward and compress the spring 32. When the protruding part of the cam 36 leaves the fixed pulley 33, the spring 32 returns to its original position and pushes the slide rod 31 to move upward. Through this reciprocating motion, the lifting frame 37 at the bottom of the slide rod 31 drives the electric push rod 38 and the clamping assembly 4 to move up and down as a whole. At the same time, the electric push rod 38 can extend and retract to adjust the height of the lifting frame 41, ensuring that the shut-off valve body 5 can be completely immersed in the anti-corrosion paint in the anti-corrosion paint box 6. During the immersion process, the reciprocating motion of the slide rod 31 causes the shut-off valve body 5 to shake slightly, which can effectively avoid residual air bubbles on its surface and ensure uniform paint adhesion.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the clamping assembly 4 includes a second lifting frame 41 and a bidirectional threaded rod 42. The second lifting frame 41 is fixedly connected to the output end of the electric push rod 38. The bidirectional threaded rod 42 is connected to the inner side wall of the second lifting frame 41 by a bearing. A clamping plate 43 is threadedly connected to the side wall of the bidirectional threaded rod 42. The clamping plate 43 is slidably connected to the second lifting frame 41. The clamping assembly 4 also includes a knob 44, which is fixedly connected to one end of the bidirectional threaded rod 42. A shut-off valve body 5 is provided on one side of the clamping plate 43, and the shut-off valve body 5 is located in the middle of the clamping plate 43.

[0034] In this embodiment, the operator turns the knob 44 to drive the bidirectional threaded rod 42 to rotate. Since the clamping plate 43 is threadedly connected to the bidirectional threaded rod 42 and slidably connected to the lifting frame 41, the rotation of the bidirectional threaded rod 42 will cause the clamping plates 43 on both sides to move closer to each other, thereby firmly clamping the shut-off valve body 5 in the middle. The thread helix angle is less than or equal to the equivalent friction angle.

[0035] Reference Figures 1 to 4 In one aspect of this embodiment, the protective component 7 includes a protective plate 71, which is disposed on the top of the anti-corrosion paint box 6. The protective component 7 also includes a sliding plate 72 and a sliding groove 73. The sliding plate 72 is fixedly installed on the bottom of the protective plate 71, and the sliding groove 73 is opened on the top of the base plate 1. The sliding plate 72 and the sliding groove 73 are slidably connected. The protective component 7 also includes an iron plate 74 and a magnet 75. The iron plate 74 is fixedly installed on the bottom of the protective plate 71, and the magnet 75 is fixedly installed on one side of the anti-corrosion paint box 6. The iron plate 74 and the magnet 75 are magnetically connected.

[0036] In this embodiment, after the anti-corrosion treatment is completed, the protective component 7 can protect the anti-corrosion paint box 6: the operator pushes the protective plate 71 so that the sliding plate 72 at its bottom slides along the sliding groove 73 of the bottom plate 1 until the protective plate 71 covers the top of the anti-corrosion paint box 6; at this time, the iron plate 74 at the bottom of the protective plate 71 is magnetically attracted to the magnet 75 on one side of the anti-corrosion paint box 6, fixing the protective plate 71, thereby reducing the contact between the anti-corrosion paint and the external environment, preventing the paint from losing its fluidity due to temperature changes or impurities, and ensuring the effect of subsequent anti-corrosion treatment.

[0037] Working principle: When the operator turns the knob 44, the bidirectional threaded rod 42 rotates. Since the clamping plate 43 is threadedly connected to the bidirectional threaded rod 42 and slidably connected to the lifting frame 41, the rotation of the bidirectional threaded rod 42 will cause the clamping plates 43 on both sides to move closer to each other, thereby firmly clamping the shut-off valve body 5 in the middle. The thread helix angle is less than or equal to the equivalent friction angle.

[0038] The motor 35 drives the cam 36 to rotate. During the rotation of the cam 36, it periodically squeezes the fixed pulley 33 at the top of the slide rod 31, forcing the slide rod 31 to slide downward and compress the spring 32. When the protruding part of the cam 36 leaves the fixed pulley 33, the spring 32 returns to its original position and pushes the slide rod 31 to move upward. Through this reciprocating motion, the lifting frame 37 at the bottom of the slide rod 31 drives the electric push rod 38 and the clamping assembly 4 to move up and down as a whole. At the same time, the electric push rod 38 can extend and retract to adjust the height of the lifting frame 41, ensuring that the shut-off valve body 5 can be completely immersed in the anti-corrosion paint in the anti-corrosion paint box 6. During the immersion process, the reciprocating motion of the slide rod 31 causes the shut-off valve body 5 to shake slightly, which can effectively avoid residual air bubbles on its surface and ensure uniform paint adhesion.

[0039] After the anti-corrosion treatment is completed, the protective component 7 can protect the anti-corrosion paint box 6: the operator pushes the protective plate 71, so that the sliding plate 72 at its bottom slides along the sliding groove 73 of the base plate 1 until the protective plate 71 covers the top of the anti-corrosion paint box 6; at this time, the iron plate 74 at the bottom of the protective plate 71 is magnetically attracted to the magnet 75 on one side of the anti-corrosion paint box 6, fixing the protective plate 71, thereby reducing the contact between the anti-corrosion paint and the external environment, preventing the paint from losing its fluidity due to temperature changes or impurities, and ensuring the effect of subsequent anti-corrosion treatment.
