Description

Technical fields:

[0001] This utility model relates to the field of slide gate valves, specifically to a water-cooled slide gate valve. Background technology:

[0002] Industrial slide gate valves are categorized into electric, manual, and pneumatic types. They are primarily used in liquid pipelines containing large particles and are also suitable for pipelines transporting solid or dusty materials. Slide gate valves perfectly match the flow of the medium inside the pipeline, and when closed, their sealing performance meets enterprise standards.

[0003] During the drying process of semi-coke, high-temperature waste residue is generated. During the conveying process, a slide gate valve is needed to control the conveying volume. The high temperature of the material will frequently burn the slide gate, making it unusable. In order to prevent damage to the slide gate valve, water-cooled slide gate valves are mostly used.

[0004] There are many types of water-cooled slide gate valves available, but most of them use internal circulating water pipes to achieve the purpose of heat dissipation.

[0005] The circulating water pipes are located inside the valve body, making them extremely susceptible to damage due to deformation. They are difficult to replace as a whole and lack protection.

[0006] Therefore, a slide gate valve is needed that can provide sufficient support to prevent valve body deformation and facilitate the replacement of the internal circulation pipe. Utility model content:

[0007] The purpose of this utility model is to provide a water-cooled slide gate valve.

[0008] This utility model is implemented by the following technical solution:

[0009] A water-cooled slide gate valve includes a valve body, a cylinder fixedly mounted on the valve body, a sealing plate fixedly mounted on the output end of the cylinder, an upper valve plate and a lower valve plate inserted into the valve body, an upper buckle plate provided at the bottom end of the upper valve plate, the upper buckle plate being U-shaped in general and L-shaped in cross section, the top of the lower valve plate being U-shaped in general and L-shaped in cross section, a sealing groove provided on the outer wall of the lower valve plate, two pads fixedly connected to one side of the sealing plate, and several support plates fixedly connected between the two pads, the support plates being inverted U-shaped and inclined on both sides.

[0010] Preferably, a circulation tube is inserted into the sealing plate, and baffles are fixedly connected to both ends of the circulation tube. Multiple insertion rods are fixedly connected to each baffle. Multiple insertion holes are provided on the sealing plate, and each insertion rod is inserted into the corresponding insertion hole and is tightly fitted therewith.

[0011] Preferably, a sealing gasket is filled between the upper valve plate and the lower valve plate, and multiple threaded holes are provided on both the upper valve plate and the lower valve plate.

[0012] The advantages of this utility model are: it is equipped with an upper valve plate and a lower valve plate, which are interlocked and spliced ​​by the pads set on the sealing plate, and then fixed with bolts to complete the assembly. The operation is simple. It is equipped with several support plates, which can effectively prevent the upper valve plate from deforming and protect the circulation pipe. At the same time, the disassembly and installation of the circulation pipe is very convenient, which can effectively improve maintenance efficiency. Attached image description:

[0017] like Figures 1 to 3 As shown, a water-cooled slide gate valve includes a valve body 1, a cylinder 2 fixedly mounted on the valve body 1, a sealing plate 4 fixedly mounted on the output end of the cylinder 2, an upper valve plate 3 and a lower valve plate 5 inserted into the valve body 1, an upper buckle plate at the bottom of the upper valve plate 3, the upper buckle plate being U-shaped with an L-shaped cross section, the top of the lower valve plate 5 being U-shaped with an L-shaped cross section, a sealing groove on the outer wall of the lower valve plate 5, two pads 6 fixedly connected to one side of the sealing plate 4, and several support plates 8 fixedly connected between the two pads 6, the support plates 8 being inverted U-shaped with inclined sides, dividing the entire valve plate into the upper valve plate 3 and the lower valve plate 5, facilitating splicing and insertion of the internal circulation pipe 7, and the presence of several support plates 8 effectively prevents deformation of the upper valve plate 3, increasing support force; if the upper valve plate 3 deforms, it can be replaced without replacing the entire valve plate, thus saving costs.

[0018] A circulation tube 7 is inserted into the sealing plate 4. Both ends of the circulation tube 7 are fixedly connected to baffles 10. Each baffle 10 is fixedly connected to multiple insertion rods 12. The sealing plate 4 is provided with multiple insertion holes 11. Each insertion rod 12 is inserted into the corresponding insertion hole 11 and fits tightly with it. When installing the circulation tube 7, multiple insertion rods 12 are used for positioning. The insertion rod 12 can be directly inserted into the insertion hole 11 to complete the installation. The insertion rod 12 and the insertion hole 11 adopt an interference fit to ensure its stability.

[0019] A sealing gasket is filled between the upper valve plate 3 and the lower valve plate 5. Both the upper valve plate 3 and the lower valve plate 5 are provided with multiple threaded holes 9. The threaded holes 9 are engaged with bolts to fix the sealing plate 4 to the upper valve plate 3 and the lower valve plate 5.
