Special valves are one of the indispensable valves in industrial production. They can meet the requirements of special working conditions, ensure the normal and stable operation of the pipeline system, and also provide important support for the development of various industries.

[0003] After searching, a Chinese patent with publication number CN212776281U discloses an insulation structure for a special valve, which includes a valve body and a T-shaped sleeve. There are two T-shaped sleeves, and the combined inner radius of the T-shaped sleeves is larger than the outer radius of the valve body pipeline. The tops of both sides of the T-shaped sleeves are integrally formed with a first fixing plate. The utility model has the advantages of good insulation effect and corrosion resistance.

[0026] An embodiment of the present utility model provides a special valve with a heat preservation structure.

[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 , which includes a valve body 1. An external disassembly and assembly mechanism 2 is provided on the valve body 1. The disassembly and assembly mechanism 2 includes an arc-shaped mounting plate 201. The arc-shaped mounting plate 201 is composed of two arc-shaped plates hinged together and can rotate freely through a hinge shaft.

[0028] The outer surface of the arc-shaped mounting plate 201 is fixedly connected with a first fixing plate 202 and a second fixing plate 203. The outer surfaces of the first fixing plate 202 and the second fixing plate 203 are fixedly connected with a driving motor 204. The output end of the driving motor 204 is fixedly connected with a telescopic rod 205. The telescopic end of the telescopic rod 205 is fixedly connected with a driving sprocket 206. By operating the driving motor 204, the telescopic rod 205 can be effectively driven to rotate the driving sprocket 206.

[0029] The outer surface of the driving sprocket 206 is drivingly connected with a chain 207. The outer surface of the chain 207 is drivingly connected with a driven sprocket 208. The outer surface of the driven sprocket 208 is fixedly connected with a threaded rod 209. By the rotation of the driving sprocket 206 and the transmission of the chain 207, the threaded rod 209 can be effectively driven to rotate to make the protection mechanism 3 move.

[0030] The outer surface of the threaded rod 209 is threadedly connected with the arc-shaped mounting plate 201. The outer surface of the first fixing plate 202 is fixedly connected with a limiting rod 210. The outer surface of the limiting rod 210 is slidably connected with the second fixing plate 203. By inserting the limiting rod 210 into the inner wall of the second fixing plate 203, the valve body 1 can be effectively closed.

[0031] A plug rod 211 is slidably connected to the inner wall of the limiting rod 210. The outer surface of the plug rod 211 is slidably connected with a fixing bracket 212. The outer surface of the fixing bracket 212 is fixedly connected with the second fixing plate 203. By inserting the plug rod 211 into the inner walls of the second fixing plate 203 and the limiting rod 210, the limiting rod 210 can be effectively limited to prevent the limiting rod 210 from sliding out of the inside of the second fixing plate 203.

[0032] A telescopic spring 213 is sleeved on the outer surface of the plug rod 211. One end of the telescopic spring 213 is fixedly connected with the plug rod 211, and the end of the telescopic spring 213 away from the plug rod 211 is fixedly connected with the fixing bracket 212. One end of the plug rod 211 is fixedly connected with a pulling plate 214. Due to the resilience of the telescopic spring 213, the plug rod 211 can be inserted into the inner wall of the limiting rod 210 more quickly and conveniently.

[0033] Please refer to again Figure 2 and Figure 4 There is a protection mechanism 3 outside the valve body 1. The protection mechanism 3 includes an anti-corrosion layer 301. The outer surface of the anti-corrosion layer 301 is rotationally connected with the threaded rod 209. The outer surface of the anti-corrosion layer 301 is coated with anti-corrosion paint, which effectively makes the device play an anti-corrosion role.

[0034] The outer surface of the corrosion-resistant layer 301 is fixedly connected to a strengthening layer 302, and the outer surface of the strengthening layer 302 is fixedly connected to a sealing layer 303. The setting of the strengthening layer 302 effectively improves the structural strength of the protection mechanism 3 and reduces the probability of damage during use. The setting of the sealing layer 303 effectively plays a sealing role to prevent the harmful gas from being emitted outward due to overheating of the valve body 1.

[0035] The outer surface of the sealing layer 303 is fixedly connected to a moisture-proof layer 304, and the outer surface of the moisture-proof layer 304 is fixedly connected to a heat-insulating layer 305. The moisture-proof layer 304 is made of polyurethane material, which effectively prevents moisture from entering and causing the temperature of the valve body 1 to drop. The interior of the heat-insulating layer 305 is filled with heat-insulating cotton, which effectively plays a heat-insulating effect on the valve body 1.

[0036] The drive motor 204 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure too much, and it can also be replaced by other power sources.

[0037] When this utility model is in use: First, pull the pulling plate 214 to make the telescopic spring 213 contract and deform, so that the insertion rod 211 slides out from the inner wall of the second fixing plate 203. At this time, rotate the arc-shaped mounting plate 201 so that the limiting rod 210 on the surface of the first fixing plate 202 is inserted into the inner wall of the second fixing plate 203. Then release the pulling plate 214, and with the resilience of the telescopic spring 213, the insertion rod 211 is effectively ejected into the inner walls of the second fixing plate 203 and the insertion rod 211, locking the arc-shaped mounting plate 201 into a circular state. At this time, simultaneously start the two drive motors 204 to make the telescopic rod 205 rotate. The rotation of the telescopic rod 205 drives the driving sprocket 206 to rotate. The rotation of the driving sprocket 206 drives the chain 207 to drive. The driving of the chain 207 drives the driven sprocket 208 to rotate. The rotation of the driven sprocket 208 drives the threaded rod 209 to rotate. The rotation of the threaded rod 209 drives the protection mechanism 3 to move until the protection mechanism 3 contacts the surface of the valve body 1, thus completing the installation of heat preservation and protection. The setting of the corrosion-resistant layer 301 effectively plays an anti-corrosion role, increasing the service life of the device. The setting of the strengthening layer 302 effectively improves the structural strength of the protection mechanism 3, avoiding damage during use. The setting of the sealing layer 303 effectively plays a sealing role, preventing the harmful gas from being emitted outward due to the temperature rise of the valve body 1. The setting of the moisture-proof layer 304 effectively plays a moisture-proof role, preventing the temperature of the valve body 1 from dropping due to moisture. The setting of the heat-insulating layer 305 effectively plays a heat-insulating role on the valve body 1. Through the five-fold multiple protections, the valve body 1 is more secure during use.
