Description

Technical Field

[0001] This invention relates to the field of valve protective sleeve technology, specifically a protective sleeve for stainless steel valves and flanges that enhances the insulation of irregularly shaped surfaces. Background Technology

[0002] As the name suggests, a valve protective sleeve is a protective component used to protect the outer surface of a valve. By filling the inside of the protective component with insulation material, the sleeve can provide both protection and insulation, thereby reducing temperature loss between the pipeline and the valve and improving transmission efficiency. The valve protective sleeve also reduces heat exchange between the insulated body and the external environment, thus ensuring the necessary temperature for production. However, existing valve protective sleeves still have some problems in use, such as:

[0003] Existing valve protective sleeves have an unstable internal insulation layer, which means that users often need to fix the insulation layer before connecting the valve protective sleeves during disassembly and installation. In addition, existing valve protective sleeves are generally too short to protect flanges simultaneously, resulting in localized temperature loss between the pipeline and the flange, making it difficult for the equipment to reach the required operating temperature quickly. Therefore, an improved device is needed to address these problems. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a protective sleeve for stainless steel valves and flanges that enhances the insulation of irregularly shaped surfaces.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a protective sleeve for stainless steel valves and flanges with enhanced thermal insulation of irregularly shaped surfaces, including a first docking protection mechanism, a second docking protection mechanism slidably installed on the side end of the first docking protection mechanism, enhanced isolation devices fixedly installed at both ends of the first and second docking protection mechanisms, second support corner plates fixedly installed at the top and bottom ends of the outer two sides of the first docking protection mechanism, first support corner plates fixedly installed at positions of the second docking protection mechanism relative to the second support corner plates, a rotating bracket rotatably installed inside the side end of the first support corner plate away from the second docking protection mechanism, a connecting screw symmetrically fixedly installed at one end of the rotating bracket near the second support corner plate, and a nut threaded onto the end of the connecting screw away from the rotating bracket.

[0006] Preferably, the first docking protection mechanism includes an insulation layer, a polyurethane insulation layer, an extension guide rod, an arc-shaped heat-conducting groove, an extension adapter ring frame, a sealing device, an outer tube, and a mating clamping plate. The arc-shaped heat-conducting groove is formed inside the extension adapter ring frame. The extension adapter ring frame is fixedly installed on both ends of the outer tube. The sealing device is fixedly installed on both ends of the outer tube and is located between two extension adapter ring frames. The extension guide rod is symmetrically and equidistantly fixedly installed at the bottom of the inner end of the outer tube. The mating clamping plate is slidably sleeved on the extension guide rod. The polyurethane insulation layer is fixedly installed on the mating clamping plate and is fixedly installed inside the side end of the polyurethane insulation layer opposite to the outer tube.

[0007] Preferably, the sealing device includes a limiting screw, an arc bracket, a sealing isolation plate, and a supporting outer frame. The limiting screw is threaded into the inside of the supporting outer frame. The arc bracket is rotatably installed at one end of the limiting screw. The sealing isolation plate is fixedly installed on the side end of the arc bracket away from the limiting screw.

[0008] Preferably, the reinforced isolation device includes a rubber washer, a limiting spring, a movable groove, and a connecting arc plate. The movable groove is opened at the inner center of the connecting arc plate. The limiting spring is fixedly installed at the inner top of the movable groove and is arranged in a ring. The rubber washer is fixedly installed at the bottom end of the limiting spring.

[0009] Preferably, the mating plate has equidistant insertion holes adapted to the extension guide rod on the side end near the polyurethane insulation layer; the inner surface of the closed isolation plate is flush with the outer surface of the extension adapter ring; the closed isolation plate and the insulation layer are filled with sponge; the supporting outer frame is fixedly installed on the outer surface of the outer tube away from the polyurethane insulation layer; the connecting arc plate is fixedly installed on both ends of the outer tube; the rubber gasket is made of chlorohydrin rubber; the second supporting corner plate has symmetrically formed docking grooves adapted to the connecting screw on the side end away from the first docking protection mechanism; and the width of the closed isolation plate is the same as the width of the extension adapter ring.

[0010] Preferably, the arc-shaped heat-conducting groove is located at both ends inside the outer sleeve, and the width of the arc-shaped heat-conducting groove is greater than the overall thickness of the outer flange.

[0011] Preferably, the first docking protection mechanism and the second docking protection mechanism adopt the same structural configuration.

[0012] Preferably, the outer sleeve is made of stainless steel.

[0013] Preferably, the thermal insulation layer and the polyurethane thermal insulation layer are connected in an integrated manner.

[0014] The beneficial effects of this invention are:

[0015] First, the first and second docking protection mechanisms are designed with a split structure, and their internal structures and external shapes are identical, facilitating their docking and assembly. Furthermore, the rotating bracket and nut are used for adaptive connection, allowing the first and second docking protection mechanisms to be fixedly installed together. An enhanced insulation device is fixedly installed inside the first docking protection mechanism to reduce heat loss from the valve's interior. An extended protection device is also fixedly installed inside the first docking protection mechanism to facilitate flange protection.

The insulation layer of the first docking protection mechanism can be assembled in sections, making it easy for users to disassemble or install the insulation layer. The reinforced isolation device protects both ends of the first and second docking protection mechanisms, preventing cold air from entering the interior of the second and first docking protection mechanisms and improving their insulation performance.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, the protective sleeve for stainless steel valves and flanges with enhanced surface insulation of irregular shapes according to the present invention includes a first docking protection mechanism 1, a second docking protection mechanism 2 slidably installed on the side end of the first docking protection mechanism 1, and a reinforced isolation device 3 fixedly installed at both ends of the first docking protection mechanism 1 and the second docking protection mechanism 2. The top and bottom ends of the outer sides of the first docking protection mechanism 1 are respectively fixedly installed with second support angle plates 5. The second docking protection mechanism 2 is respectively fixedly installed with first support angle plates 4 at positions relative to the second support angle plates 5. A rotating bracket 8 is rotatably installed inside the side end of the first support angle plate 4 away from the second docking protection mechanism 2. A connecting screw 7 is symmetrically fixedly installed at the end of the rotating bracket 8 near the second support angle plate 5, and a nut 6 is threaded onto the end of the connecting screw 7 away from the rotating bracket 8.

[0027] The first docking protection mechanism 1 includes an insulation layer 9, a polyurethane insulation layer 10, an extension guide rod 11, an arc-shaped heat-conducting groove 12, an extension adapter ring frame 13, a sealing device 14, an outer tube 15, and a mating clamping plate 16. The arc-shaped heat-conducting groove 12 is opened inside the extension adapter ring frame 13. The extension adapter ring frame 13 is fixedly installed on both ends of the outer tube 15. The sealing device 14 is fixedly installed on both ends of the outer tube 15 and is located between the two extension adapter ring frames 13. The extension guide rod 11 is symmetrically and equidistantly fixedly installed at the bottom of the inner side of the outer tube 15. The mating clamping plate 16 is slidably sleeved on the extension guide rod 11. The polyurethane insulation layer 10 is fixedly installed on the mating clamping plate 16. The insulation layer 9 is fixedly installed inside the side end of the polyurethane insulation layer 10 away from the outer tube 15. By the outer wall of the insulation layer 9 and the polyurethane insulation layer 10 being attached to the inner wall of the outer tube 15, the tightness of the fit between the insulation layer 9 and the polyurethane insulation layer 10 and the outer tube 15 can be improved.

[0028] The sealing device 14 includes a limiting screw 17, an arc bracket 18, a sealing isolation plate 19, and a supporting frame 20. The limiting screw 17 is threaded into the inside of the supporting frame 20. The arc bracket 18 is rotatably installed at one end of the limiting screw 17. The sealing isolation plate 19 is fixedly installed on the side end of the arc bracket 18 away from the limiting screw 17. When the limiting screw 17 is screwed, it can drive the sealing isolation plate 19 to move simultaneously.

[0029] The reinforced isolation device 3 includes a rubber washer 21, a limiting spring 22, a movable groove 23, and a connecting arc plate 24. The movable groove 23 is located at the center of the inner side of the connecting arc plate 24. The limiting spring 22 is fixedly installed at the top of the inner side of the movable groove 23 and is arranged in a ring. The rubber washer 21 is fixedly installed at the bottom of the limiting spring 22. Through the elasticity of the limiting spring 22, the rubber washer 21 can be constantly squeezed to move downward.

[0030] The side end of the card plate 16 near the polyurethane insulation layer 10 is provided with equidistant insertion holes that are compatible with the extension guide rod 11. The inner surface of the closed isolation plate 19 is flush with the outer surface of the extension adapter ring 13. The interior of the closed isolation plate 19 and the insulation layer 9 is filled with sponge. The outer support frame 20 is fixedly installed on the outer surface of the outer tube 15 away from the polyurethane insulation layer 10. The connecting arc plate 24 is fixedly installed on both ends of the outer tube 15. The rubber gasket 21 is made of chlorohydrin rubber. The inner side of the second support corner plate 5 away from the first docking protection mechanism 1 is symmetrically provided with docking grooves that are compatible with the connecting screw 7. The width of the closed isolation plate 19 is the same as the width of the extension adapter ring 13, so that the outer ring of the extension adapter ring 13 can be closed when the closed isolation plate 19 moves.

[0031] The arc-shaped heat-conducting groove 12 is located at both ends inside the outer sleeve 15, and the width of the arc-shaped heat-conducting groove 12 is greater than the overall thickness of the outer flange. By setting the arc-shaped heat-conducting groove 12, the flange can be placed inside the arc-shaped heat-conducting groove 12, which facilitates the solution of flange leakage problem.

[0032] The first docking protection mechanism 1 and the second docking protection mechanism 2 adopt the same structure. The first docking protection mechanism 1 and the second docking protection mechanism 2 are arranged in a symmetrical and segmented manner, which facilitates the quick docking and assembly of the first docking protection mechanism 1 and the second docking protection mechanism 2, and they can be reused.

[0033] The outer sleeve 15 is made of stainless steel, which improves the overall structural strength of the device while preventing rainwater from seeping into the device.

[0034] The insulation layer 9 and the polyurethane insulation layer 10 are connected in an integrated manner. By using the integrated production of the insulation layer 9 and the polyurethane insulation layer 10 in the factory, the connection performance of the insulation layer 9 and the polyurethane insulation layer 10 can be improved. This makes it easier for the insulation layer 9 and the polyurethane insulation layer 10 to form a whole when assembled with the outer tube 15, and prevents the insulation layer 9 and the polyurethane insulation layer 10 from being damaged during the assembly of the first docking protection mechanism 1 and the second docking protection mechanism 2.

[0035] Working principle: In use, by using the matching clamping plate 16, which has equidistant insertion holes on the side end near the outer sleeve 15 that are compatible with the extension guide rod 11, the polyurethane insulation layer 10 can be moved towards the inner wall of the outer sleeve 15 until the matching clamping plate 16 is fitted around the extension guide rod 11, completing the installation of the insulation layer 9 and the polyurethane insulation layer 10. At this time, the first docking protection mechanism 1 and the second docking protection mechanism 2 can be moved towards each other until the insulation layer 9 and the polyurethane insulation layer 10 respectively come into contact with the outer surface of the valve. When the first docking protection mechanism 1 and the second docking protection mechanism 2 move towards each other until they fit together, the valve can be completely wrapped. At the same time, the rotating bracket 8 can be rotated towards one end of the second support angle plate 5, so that the second support angle plate 5 moves away from the first docking protection mechanism 1. The protective mechanism 1 has symmetrically formed mating grooves on its side end that fit the connecting screw 7, allowing the connecting screw 7 to slide into the interior of the second support angle plate 5. When the connecting screw 7 is fully rotated into the interior of the second support angle plate 5, the nut 6 can be screwed onto the connecting screw 7 towards one end of the rotating bracket 8 until the nut 6 is tightened with the second support angle plate 5, thus connecting and fitting the first docking protective mechanism 1 and the second docking protective mechanism 2. Several nuts 6, connecting screws 7, and rotating brackets 8 are respectively set at the bottom and top of the outer sides of the first docking protective mechanism 1 and the second docking protective mechanism 2. The above steps can be repeated to achieve docking and matching of other nuts 6, connecting screws 7, and rotating brackets 8, thus... This enhances the connection stability between the first docking protection mechanism 1 and the second docking protection mechanism 2. During installation, the extension adapter ring 13 is aligned with the flange on the valve. The extension adapter ring 13 is designed to bulge outwards, allowing the flange to enter its interior. Simultaneously, the limiting screw 17 is tightened, causing the arc bracket 18 and the sealing isolation plate 19 to slide along the outer surface of the extension adapter ring 13. Since the width of the sealing isolation plate 19 matches the internal width of the extension adapter ring 13, when the limiting screw 17 is tightened to its limit position, the sealing isolation plate 19 completely seals the outer ring of the extension adapter ring 13. This is achieved through the insulation layer 9 and the sealing isolation plate 19. The interior of insulation layer 9 is filled with sponge, which enhances the insulation performance of insulation layer 9 and closed isolation plate 19. Simultaneously, as the first docking protection mechanism 1 and the second docking protection mechanism 2 dock with the pipe, the pipe compresses and moves rubber gasket 21 into the movable groove 23. At the same time, due to the elasticity of the limiting spring 22, when rubber gasket 21 moves into the movable groove 23, the limiting spring 22 exerts a reaction force outward, ensuring that the compressible rubber gasket 21 remains in contact with the pipe surface. This prevents cold air from entering through the gap between the pipe and the outer sleeve 15, improving the insulation performance of the first docking protection mechanism 1 and the second docking protection mechanism 2. Furthermore, the rubber gasket 21 is made of chloroprene rubber, which allows it to withstand the heat inside the pipe without melting.When leakage detection is required at the flange connection, the limiting screw 17 can be reversed, causing the sealing isolation plate 19 to move along the surface of the extension adapter ring 13 until the flange connection gap inside the outer sleeve 15 is fully exposed. At this time, the arc-shaped heat-conducting groove 12 is opened inside the extension adapter ring 13, allowing the user to apply leakage detection liquid to the flange connection without disassembling the first docking protection mechanism 1 and the second docking protection mechanism 2, thus enabling rapid leakage detection at the flange connection. During use, the device can be quickly removed or installed on the extension guide rod 11 using the clamping plate 16, facilitating the rapid replacement and installation of the insulation layer 9 and the polyurethane insulation layer 10. Simultaneously, when the first docking protection mechanism 1 and the second docking protection mechanism 2 are fully engaged, the clamping plates 16 can be pressed together, preventing the polyurethane insulation layer 10 and the insulation layer 9 from shaking or tilting, thus improving the insulation performance inside the outer sleeve 15.
