Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a valve with a function to prevent corrosion at the switch. Background Technology

[0002] The primary function of a valve is to control fluid flow, and its sealing performance is crucial for effective operation. Valves with rust prevention features effectively prevent corrosion-induced degradation of sealing performance by using special rust-resistant materials or coatings at the opening and closing points. This ensures that the valve does not leak when closed, thus guaranteeing the stability and safety of the fluid control system.

[0003] In existing publicly available literature, patent publication number CN217583201U discloses a valve, a valve assembly, and a valve type. The valve is movably connected to a spherical body within a radial channel. One end of the spherical body is connected to an elastic element, and the other end is connected to an adjusting handle. One end of the radial channel has a step (step one) that mates with the spherical body, and the other end has a step (step two) that mates with the adjusting handle. This invention addresses the technical problem of poor flow rate and flow regulation performance. However, this technology still has the following drawbacks.

[0004] When valves are used for opening and closing, a rotating screw is usually used to rotate and raise or lower the valve, thereby closing or opening the valve. However, the screw part is prone to rusting after long-term use. Once rusted, it is difficult to open and close the valve, and the rust prevention effect is poor. Therefore, valves with rust prevention function at the switch are provided. Utility Model Content

[0006] The lubrication and rust prevention assembly includes a lubricating oil pipe, a manual valve, a lower drain pipe, a lubricating oil tank, and an inlet pipe; the lubricating oil pipe is fixed to the inner wall of the limiting ring, the manual valve is threaded to the top of the lubricating oil pipe, the lower drain pipe is fixedly connected to the top of the manual valve, and the lubricating oil tank is fixedly connected to the top of the lower drain pipe; the inlet pipe is welded to the top of the lubricating oil tank.

[0007] Preferably, the lubricating oil tank is connected to the lower drain pipe, and the lower drain pipe has a circular cross-sectional shape. A handle is fixedly connected to the outer wall of the switch screw near its top. A shut-off valve core is rotatably connected to the bottom end of the switch screw. A valve housing is slidably connected to the outer wall of the shut-off valve core, and the valve housing and the sleeve valve housing are fixedly connected. A threaded cap is threadedly connected to the outer wall of the inlet pipe, and the upper surface of the threaded cap is polygonal.

[0008] In use, lubricating oil is poured into the inlet pipe, filling the lubricating oil tank. The lubricating oil in the tank is then poured into the lower drain pipe, and through a manual valve, it is poured into the lubricating oil pipe and then into the limit ring. In this way, the lubricating oil can lubricate the outer wall of the switch screw.

[0009] Preferably, a support column is fixedly installed on the upper surface of the sleeve valve housing, and a support and protection assembly is provided at the top of the support column; the support and protection assembly includes a support ring fixedly installed at the top of the support column, and a retaining ring is fixedly connected to the upper surface of the support ring; a reinforcing column is fixedly connected to one side of the outer wall of the support ring; support blocks are fixedly installed on both sides of the sleeve valve housing, and a fixing sleeve is installed at the top of the support block; both support blocks are fixedly connected to the fixing sleeve; the retaining ring is rotatably connected to the switch screw. Multiple support columns are arranged in a circular, equidistant distribution, and the cross-sectional shape of the support ring is circular. The support blocks are fixedly connected to the reinforcing columns, and the inner wall of the retaining ring is a smooth surface.

[0010] In use, the support column provides support to the support ring, the valve shell supports two support blocks, and the two support blocks support the fixed sleeve. In this way, the switch screw can rotate stably inside the fixed sleeve, and the switch screw rotates upward along the inner wall of the retaining ring, so that the retaining ring can fit and rotate with the switch screw.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model adopts a lubrication and anti-rust component. Lubricating oil is poured into the inlet pipe and then into the lubricating oil tank. When the manual valve is opened, the lubricating oil in the lubricating oil tank is poured into the lower drain pipe and then into the limit ring. In this way, the lubricating oil can lubricate the outer wall of the switch screw, preventing rust from forming at the connection between the switch screw and the sleeve valve body. The limit ring is filled with lubricating oil, which has a better anti-rust effect.

[0013] 2. This utility model adopts a support and protection component. The support column provides support force to the support ring, the support ring supports the retaining ring, and the two support blocks support the fixing sleeve. In this way, the switch screw can rotate stably inside the fixing sleeve, and the retaining ring can rotate in close contact with the switch screw, preventing external moisture from entering the holes in the inner wall of the retaining ring, thus improving the moisture ingress effect.

[0020] 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.

[0021] As attached Figure 1-5 The valve shown has a function of preventing corrosion at the switch. The valve is equipped with a lubrication and anti-corrosion component. The lubrication and anti-corrosion component can lubricate the outer wall of the switch screw 2 with lubricating oil, so as to prevent rust from forming at the connection between the switch screw 2 and the sleeve valve body 1. The limit is filled with lubricating oil, and the anti-corrosion effect is better. The specific structure of the lubrication and anti-corrosion component is as follows.

[0022] In this embodiment, as shown in the appendix Figure 1-2 As shown, the switch screw 2 is threadedly connected to the inner wall of the sleeve valve housing 1, and the limiting ring 3 is fixedly connected to the upper surface of the sleeve valve housing 1. The inner wall of the limiting ring 3 is provided with a lubrication and anti-corrosion component. The lubrication and anti-corrosion component includes a lubricating oil pipe 4, a manual valve 5, a lower drain pipe 6, a lubricating oil tank 7, and an inlet pipe 8. The lubricating oil pipe 4 is fixed to the inner wall of the limiting ring 3, the manual valve 5 is threadedly connected to the top of the lubricating oil pipe 4, the lower drain pipe 6 is fixedly connected to the top of the manual valve 5, and the lubricating oil tank 7 is fixedly connected to the top of the lower drain pipe 6. The inlet pipe 8 is welded to the top of the lubricating oil tank 7. The lubricating oil tank 7 and the lower drain pipe 6 are connected, and the cross-sectional shape of the lower drain pipe 6 is circular.

[0023] In this embodiment, as shown in the appendix Figure 1-4 As shown, a handle 9 is fixedly connected to the outer wall of the switch screw 2 near its top. A shut-off valve core 10 is rotatably connected to the bottom end of the switch screw 2. A valve housing 11 is slidably connected to the outer wall of the shut-off valve core 10, and the valve housing 11 is fixedly connected to the sleeve valve housing 1 so that the shut-off valve core 10 can move upward along the inner wall of the valve housing 11. A threaded cap 12 is threadedly connected to the outer wall of the inlet pipe 8, and the upper surface of the threaded cap 12 is polygonal in shape so that the threaded cap 12 can be threadedly separated from the inlet pipe 8 by rotating the threaded cap 12 in the forward direction.

[0024] This technology features a valve with anti-rust function at the switch. During use, rotating the threaded cap 12 forward separates it from the inlet pipe 8, allowing lubricating oil to be poured into the inlet pipe 8. The lubricating oil then flows through the inlet pipe 8 into the lubricating oil tank 7, filling it completely. Then, the manual valve 5 is opened, allowing the lubricating oil in the tank 7 to flow into the lower drain pipe 6, then into the manual valve 5, and finally into the lubricating oil pipe 4. Finally, the lubricating oil flows into the limit ring 3, thus completing the lubrication process. The oil lubricates the outer wall of the switch screw 2. Then, the handle 9 is turned, which drives the switch screw 2 to rotate. The switch screw 2 rotates inside the sleeve valve housing 1, thus rotating on the cut-off valve core 10. At the same time, the cut-off valve core 10 can move upward along the inner wall of the valve housing 11. In this way, the switch screw 2 can come into contact with the lubricating oil inside the limit ring 3 for better lubrication of the switch screw 2, thereby preventing rust from forming at the connection between the switch screw 2 and the sleeve valve housing 1. The rust prevention effect at the connection between the sleeve valve housing 1 and the switch screw 2 is better.

[0025] In this embodiment, as shown in the appendix Figure 4-5As shown, a support column 13 is fixedly installed on the upper surface of the sleeve valve housing 1, and a support and protection assembly is provided at the top of the support column 13. The support and protection assembly includes a support ring 14 fixedly installed at the top of the support column 13, and a retaining ring 15 is fixedly connected to the upper surface of the support ring 14. A reinforcing column 16 is fixedly connected to one side of the outer wall of the support ring 14. Support blocks 17 are fixedly installed on both sides of the sleeve valve housing 1, and a fixing sleeve 18 is installed at the top of the support block 17. Both support blocks 17 are fixedly connected to the fixing sleeve 18. The retaining ring 15 is rotatably connected to the switch screw 2. Multiple support columns 13 are arranged in a circular ring at equal intervals. The cross-sectional shape of the support ring 14 is circular. The support blocks 17 are fixedly connected to the reinforcing column 16, and the inner wall of the retaining ring 15 is a smooth surface.

[0026] In use, this technology supports multiple support pillars 13 by connecting the valve housing 1. The support pillars 13 provide support force to the support ring 14, and the support ring 14 supports the retaining ring 15. At the same time, the valve housing 1 supports two support blocks 17, which support the reinforcing column 16 and the fixing sleeve 18. In this way, the switch screw 2 can rotate stably inside the fixing sleeve 18, and the switch screw 2 rotates upward along the inner wall of the retaining ring 15. Thus, the retaining ring 15 can fit and rotate with the switch screw 2, thereby preventing external moisture from entering the holes in the inner wall of the retaining ring 15.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
