Description

Technical Field

[0001] This invention belongs to the field of valve high-pressure alarm technology, specifically, it relates to a high-pressure warning valve and a leak-proof stainless steel valve insulation sleeve. Background Technology

[0002] Valves are devices installed on pipelines to control the direction, pressure, and flow rate of fluids, such as liquids and gases. Valves are key control components in fluid transport systems and have multiple functions, including shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, and overflow pressure relief. In the process of wastewater regeneration treatment, valves can achieve precise control of wastewater flow rate. By controlling the flow rate in the wastewater regeneration treatment process, the controllability of wastewater in each purification stage can be effectively increased.

[0003] Chinese Patent CN223152951U discloses a valve with a high-pressure alarm function, including a valve body, a pressure gauge, and an audible and visual alarm. The pressure gauge and the audible and visual alarm are mounted on the top of the valve body, and the pressure gauge is electrically connected to the audible and visual alarm. A side bolt is fixed to the top side of the valve body, and the side bolt passes through a limiting window. The limiting window is located at the bottom of a support plate, and a cover is installed on the top of the support plate. A positioning plate is fixed to the bottom of the valve body, and a vertical plate is fitted to the outer side of the positioning plate. The outer side of the vertical plate is rotatably connected to the top of a support rod, and the bottom of the support rod is rotatably connected to the top surface of one end of a base plate. This valve with a high-pressure alarm function adopts a novel structural design, which not only provides stable protection for the top electrical control components and alarm mechanism, but also features a height- and posture-adjustable support structure at the bottom, enabling stable support and positioning of the valve under different operating environments.

[0004] However, this technical solution still has at least the following drawbacks: the solution only protects electrical components such as the valve's pressure gauge and audible and visual alarm. When the valve is over-pressurized, the pressure can be reduced by adjusting the pipeline to ensure that the valve can control the water pressure during the sewage treatment process. Therefore, it is necessary to remind workers that the valve pressure is high when operating the valve, but the above technical solution does not have the function of reminding them when operating the valve. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a high-pressure warning valve and a leak-proof stainless steel valve insulation sleeve. An alarm is installed on the valve, and a pressure feedback mechanism transmits the pressure to a triggering mechanism, causing the movement of the moving parts to differ under high and normal pressure conditions, thus activating the alarm. The valve is insulated by a protective tube and a heat insulation plate. The heat insulation plate is multi-layered and made of various heat-insulating fibers, effectively enhancing its insulation effect. The heat insulation plate can be rotated open to form a finned structure, allowing for rapid heat dissipation when needed. An installation unit allows for quick assembly and disassembly of the entire device. During installation, the device is sealed to the valve stem by pressing against the sealing element. An air chamber and piston are used for air blowing, which accelerates the discharge of internal hot air when the heat insulation plate is opened.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0056] Example 1

[0057] like Figures 13 to 19 As shown, a high-pressure warning valve includes a valve body 400, and an inner cavity 401 is opened at the top of the valve body 400. A valve shaft 403 and a valve stem 412 are installed in the inner cavity 401. A triggering mechanism is provided in the inner cavity 401. The triggering mechanism includes a rocker arm 404 fixedly installed on the valve shaft 403 and a rotating rod 413 fixedly installed on the valve stem 412. The axes of the valve stem 412 and the valve shaft 403 are not collinear. A valve disc 402 is installed inside the valve body 400.

[0058] An alarm mechanism is also provided inside the inner cavity 401. The alarm mechanism includes a switch 422 and an alarm 423. After the switch 422 is triggered, it controls the alarm 423 to sound an alarm. The switch 422 is installed at the bottom of the inner cavity 401. A mounting base 411 is installed at the top of the inner cavity 401. The valve stem 412 moves through the mounting base 411 and extends to the outside. The alarm 423 is installed inside the mounting base 411.

[0059] A transmission mechanism is provided between the alarm mechanism and the triggering mechanism. The transmission mechanism includes a moving part 407, and a first push rod 408 is fixedly installed at both ends of the moving part 407. A second push rod 409 is fixedly installed at one end of the first push rod 408. A fixed plate 410 is movably sleeved on the first push rod 408, and the fixed plate 410 is fixedly connected to the inner cavity 401 of the valve body 400.

[0060] The inner cavity 401 is also equipped with a pressure feedback mechanism, which includes a lifting frame 427. A lifting rod 425 is fixedly installed at the bottom of the lifting frame 427. When the pressure inside the valve body 400 increases, it causes the lifting rod 425 and the lifting frame 427 to rise. At this time, when the valve stem 412 is turned, the alarm mechanism is activated through the triggering mechanism and the transmission mechanism.

[0061] like Figures 15 to 19 As shown, the triggering mechanism also includes a first rotating member 405 and a second rotating member 415 that are rotatably connected to each other. The first rotating member 405 and the second rotating member 415 are respectively movably sleeved on the rocker arm 404 and the rotating rod 413. The bottom of the first rotating member 405 and the top of the second rotating member 415 are respectively fixedly installed with a first stop shaft 406 and a second stop shaft 416. The first stop shaft 406 is movably connected in the moving member 407, and the moving member 407 is arc-shaped with the valve stem 412 as the center.

[0062] Support rings 414 are fixedly installed at both ends of the rotating rod 413, and the support rings 414 are rotatably connected to the inner cavity 401 of the valve body 400 so that the valve rod 412 maintains the direction of the valve rod 412 when it drives the rotating rod 413 to rotate.

[0063] like Figures 15 to 16 As shown, the triggering mechanism also includes a guide plate 417, which is aligned with the second stop shaft 416. A locking plate 420 is fixedly installed between the two ends of the guide plate 417. A plug rod 418 is fixedly installed on one side of the guide plate 417. The plug rod 418 is movably inserted into the side wall of the inner cavity 401 of the valve body 400. A third spring 419 is movably sleeved on the plug rod 418. An installation rod 421 is movably inserted into the locking plate 420. The installation rod 421 is fixedly installed on the valve body 400.

[0064] When the guide plate 417 is not pushed by the second stop shaft 416, it is always kept on one side under the action of the third spring 419, and at this time the trajectory of the guide plate 417 is an arc with the valve shaft 403 as the center.

[0065] The pressure feedback mechanism also includes a circular hole at the bottom of the inner cavity 401 of the valve body 400, a lifting rod 425 is movably connected in the circular hole, a diaphragm 424 is fixedly and sealed on the inner wall of the circular hole, the diaphragm 424 is fixedly connected to the lifting rod 425, and a fourth spring 426 is movably sleeved on the lifting rod 425.

[0066] The implementation principle of a high-pressure warning valve in this embodiment is as follows:

[0067] When the pressure inside the valve body 400 does not exceed the safe range, under the elastic force of the fourth spring 426, the lifting rod 425 and the lifting frame 427 are in the lowered state. At this time, the lifting frame 427 abuts against the second push rod 409 so that the moving part 407 cannot move to one side. When the valve is opened or closed, the valve rod 412 rotates and drives the rotating rod 413 to rotate. The rotating rod 413 drives the second rotating part 415 to rotate. The second rotating part 415 drives the first rotating part 405 to move along with it. The first rotating part 405 moves along the moving part 407 through the first stop shaft 406. During the movement, it drives the valve shaft 403 to rotate through the swing rod 404, thereby controlling the rotation of the valve disc 402. At the same time, when the first rotating part 405 moves along the moving part 407, the second rotating part 415 and the second stop shaft 416 move along with it. During this process, it drives the guide plate 417 to move to one side.

[0068] When the pressure inside the valve body 400 exceeds the safe range, the high pressure acts on the diaphragm 424, causing the lifting rod 425 and the lifting frame 427 to rise. At this time, the bend of the lifting frame 427 aligns with the second push rod 409, so that the second push rod 409 is no longer blocked by the lifting frame 427. At the same time, when the lifting frame 427 rises, it blocks the locking plate 420. At this time, the guide plate 417 remains stationary. When the valve is operated, the second stop shaft 416 moves along the trajectory of the guide plate 417. During the movement, the second rotating member 415 and the first rotating member 405 drive the first stop shaft 406 to move along with it. During the movement, the first stop shaft 406 blocks the moving member 407, causing the moving member 407 to move to one side. During the movement, the switch 422 is pressed, causing the alarm 423 to activate.

[0069] Example 2

[0070] like Figures 1 to 10 As shown, a leak-proof stainless steel valve insulation sleeve is used to insulate a high-pressure warning valve, comprising:

[0071] The heat insulation unit includes a protective tube 100 with a groove. An opening and closing mechanism is provided in the groove. The opening and closing mechanism includes a heat insulation plate 101, which is rotatably installed in the groove. The heat insulation unit realizes the flow and isolation of heat through the opening and closing state of the heat insulation plate 101. The heat insulation unit also includes a driving mechanism located at both ends of the protective tube 100. The driving mechanism is used to drive the opening and closing mechanism to work.

[0072] The heat dissipation unit includes a sealing pipe 200, which is located at both ends of the heat insulation unit. Air blowing mechanisms are provided on both sides of the sealing pipe 200 to accelerate the air circulation inside the heat insulation unit.

[0073] The installation unit includes an installation pipe 301, which is fixedly connected to the protective pipe 100. An installation mechanism is provided on the top of the installation pipe 301, which is used to install the stainless steel valve insulation sleeve.

[0074] like Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, in a specific embodiment, a connecting pipe 103 is fixedly installed between the protective pipe 100 and the sealing pipe 200. The driving mechanism includes a lifting assembly, which includes a fixed rod 104. The fixed rod 104 is fixedly connected to the connecting pipe 103, and a connecting piece 105 is movably sleeved on the fixed rod 104. Limiting grooves 106 are formed on both sides of the connecting piece 105. The driving mechanism also includes a force-bearing assembly, which includes a connecting plate 108 and a lever 107. The lever 107 is fixedly connected to the connecting plate 108, and the lever 107 is movably connected within the limiting grooves 106. In this configuration, when the connecting piece 105 moves, the lever 107 rotates within the limiting grooves 106, causing the connecting plate 108 to rotate accordingly.

[0075] like Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, the opening and closing mechanism is further configured with multiple layers, and each layer of the opening and closing mechanism has a rotating shaft 102 installed at one end of the heat insulation plate 101. One end of the rotating shaft 102 movably passes through the protective tube 100 and extends to the outside. The driving mechanism controls the opening and closing state of the heat insulation plate 101 by controlling the rotation of the rotating shaft 102. The rotating shaft 102 is fixedly connected to the connecting plate 108. A protrusion is installed on the inner wall of the groove. The heat insulation plate 101 stops at the position of sealing the protective tube 100 by abutting against the protrusion. In this configuration, when the heat insulation plate 101 is closed, the two opposing heat insulation plates 101 rotate towards each other. When the two heat insulation plates 101 abut against the protrusion, the two heat insulation plates 101 are in a parallel state, and at this time, the two heat insulation plates 101 maintain a sealed state.

[0076] like Figures 6 to 7 As shown, the insulation unit further includes a heat preservation mechanism, which includes a housing 114. The housing 114 is fixedly connected to the protective tube 100 and the sealing tube 200. The housing 114, the protective tube 100, the sealing tube 200, and the connecting tube 103 form a closed space. The drive mechanism is located inside the closed space. A mounting plate 110 is provided inside the closed space. A pull plate 109 is rotatably mounted on one side of the mounting plate 110. The pull plate 109 is rotatably connected to the connector 105. In this configuration, the closed space formed by the housing 114, the protective tube 100, the sealing tube 200, and the connecting tube 103 can be used to reduce the heat exchange between the external environment and the inside of the protective tube 100.

[0077] like Figure 1 , Figure 2 , Figure 8 As shown, in a specific embodiment, the air blowing mechanism includes an air chamber 202, which is sealed and fixedly connected to a sealing tube 200. A piston 203 is movably connected inside the air chamber 202. A handle 204 is installed on one side of the piston 203, and a first spring 205 is provided on one side of the piston 203. A base plate 206 is threadedly connected to one end of the air chamber 202. A stop bar 207 is movably inserted into the top of the air chamber 202. The bottom of the stop bar 207 extends into the air chamber 202 and limits the piston 203. The heat dissipation unit also includes an unlocking mechanism, which includes a rotating disk 209. The rotating disk 209 is rotatably connected to the top of the air chamber 202. A guide protrusion 210 is fixedly installed on the rotating disk 209. Guide members 208 are fixedly installed on both sides of the stop bar 207. The guide protrusion 210 pushes up the guide members 208 to raise the stop bar 207. In this configuration, the rotating disk 209 drives the guide protrusion 210 to rotate. The guide protrusion 210 abuts against the guide member 208 to raise the stop rod 207. When the protective tube 100 is opened, the stop rod 207 disengages from the piston 203. At this time, the piston 203 moves under the action of the first spring 205, thereby compressing the hot air inside the protective tube 100 and causing it to escape from the heat insulation plate 101.

[0078] like Figure 6 , Figure 8 As shown, the heat dissipation unit further includes a pulling mechanism, which includes a pull rope 211. One end of the pull rope 211 is fixedly connected to the rotating disk 209. A reversing wheel 212 is installed on the sealing tube 200. The other end of the pull rope 211 passes around the reversing wheel 212 and is fixedly connected to a second connecting rod 112. A first connecting rod 111 is fixedly installed on one side of the second connecting rod 112. The first connecting rod 111 movably passes through the outer shell 114 and is fixedly connected to the mounting plate 110. A pulling member 113 is fixedly installed on the second connecting rod 112. In this configuration, when heat dissipation is required, the pulling member 113 is manually driven. The pulling member 113 drives the mounting plate 110 to move through the second connecting rod 112 and the first connecting rod 111. While the first connecting rod 111 moves, it drives the rotating disk 209 to rotate through the pull rope 211.

[0079] like Figures 3-4 , Figures 9-10As shown, in a specific embodiment, the installation unit further includes a protective shell 300, which is fixedly connected to the outer shell 114. The installation unit also includes a sealing mechanism, which includes a rotating ring 302 movably connected to the installation tube 301. A sealing element 303 is installed on the rotating ring 302, and a pressing element 304 is also installed on the rotating ring 302. The pressing element 304 is made of elastic material. A fixing seat 305 is fixedly installed on the protective shell 300. The fixing seat 305 pushes the sealing element 303 to contract through the pressing element 304. In this configuration, both the pressing element 304 and the sealing element 303 are made of rubber, and both ends of the pressing element 304 are fixedly connected to the rotating ring 302. When the pressing element 304 is compressed, the sealing element 303 is deformed by the pressure from the pressing element 304, so that the inner wall of the sealing element 303 fits against the valve stem.

[0080] like Figures 1-10 As shown, a sealing ring 201 is installed at one end of the sealing tube 200. The protective tube 100, the sealing tube 200, the protective shell 300 and their connecting structures are all provided with two symmetrically distributed sets, and the two sets of protective tubes 100 are rotatably connected. The protective tube 100, the sealing tube 200 and the protective shell 300 form a closed structure by rotation, so as to install the whole device. At the same time, the sealing ring 201 provided at the sealing tube 200 effectively enhances the overall anti-leakage effect.

[0081] like Figures 9-10 As shown, the mounting mechanism further includes a fixing block 308, which is fixedly mounted on one of the protective shells 300. A locking block 311 is mounted on the other protective shell 300. A slide rod 307 is movably inserted into the fixing block 308, and a retaining ring 310 is fixedly mounted on the slide rod 307. A second spring 309 is movably sleeved between the slide rod 307 and the retaining ring 310 and the fixing block 308. One end of the slide rod 307 is movably inserted into the fixing seat 305. A protrusion 306 is fixedly mounted on the side of the rotating ring 302. The rotating ring 302 drives the protrusion 306 to rotate, thereby pushing the slide rod 307 to move. In this configuration, when unlocking, the rotating ring 302 is rotated to disengage the protrusion 306 from the slide rod 307. At this time, the elastic force of the second spring 309 acts on the retaining ring 310, causing the slide rod 307 to reset and disengage from the locking block 311.

[0082] Example 3

[0083] like Figures 11-12As shown, the heat insulation board 101 includes a surface layer, a middle layer, and a bottom layer. The surface layer, the middle layer, and the bottom layer are all based on polyester fiber. The surface layer includes polyester fiber and ceramic fiber, wherein the ceramic fiber accounts for 30%-45%. The middle layer includes polyester fiber and silica aerogel, wherein the silica aerogel accounts for 40%-55%. The bottom layer includes polyester fiber and glass fiber, wherein the glass fiber accounts for 30%-50%. A small amount of thermoplastic adhesive fiber is mixed in the surface layer, the middle layer, and the bottom layer to effectively bond the fibers between the layers.

[0084] like Figures 11-12 As shown, the surface layer, intermediate layer and bottom layer are all made by lamination technology, and the skeleton structure is pressed into the surface layer, intermediate layer and bottom layer by mold. Based on the skeleton structure, the overall strength of the heat insulation board 101 is enhanced, and a pore structure is formed between adjacent skeletons, so that the heat insulation board 101 as a whole forms a porous structure to enhance the heat insulation performance.

[0085] The skeleton directions between adjacent layers in the surface, middle and bottom layers are perpendicular to each other, and the skeleton directions of the surface and bottom layers are perpendicular to the axial direction of the rotation of the heat insulation board 101, thereby increasing the strength of the heat insulation board 101 perpendicular to the rotation axis when it rotates.

[0086] The surface layer, middle layer, and bottom layer are fixed by a metal frame after being prepared by separate lamination. Wood fibers are glued to the side of the insulation board 101 away from the rotating side. The wood fibers are in a fluffy state after fiberization, so that when the two insulation boards 101 rotate towards each other, the fluffy wood fibers can achieve a tight connection between the two insulation boards 101, effectively reducing heat loss.

[0087] The implementation principle of a leak-proof stainless steel valve insulation sleeve in this embodiment is as follows:

[0088] During installation, the protective tube 100, sealing tube 200, protective shell 300, and installation tube 301 are installed on the valve and closed. At this time, the rotating rings 302 on both sides are assembled into a complete ring. Rotating the rotating rings 302, each rotating ring 302 is connected to the installation tubes 301 on both sides when the rotation is completed, so that the rotating rings 302 fix the installation tubes 301. At the same time, the rotating rings 302 drive the extrusion member 304 to rotate. When the extrusion member 304 abuts against the fixed seat 305, it deforms and drives the sealing member 303 to contract, so that the sealing member 303 fits tightly against the valve stem. When the rotating rings 302 rotate, they drive the protrusion 306 to rotate. When the protrusion 306 rotates, it abuts against the sliding rod 307 to move it. The sliding rod 307 inserts into the locking block 311, so that the two protective shells 300 are fixed to each other, thereby realizing the overall installation.

[0089] During heat preservation, the closed heat insulation plate 101 isolates the airflow between the outside and the inside. At the same time, the multi-layer design improves the heat preservation effect. When heat dissipation is required, the heat insulation plate 101 can be opened to allow the inside of the protective tube 100 to contact the outside. At the same time, the opened heat insulation plate 101 forms a fin structure to increase the heat dissipation effect.

[0090] When heat dissipation is required, the pull member 113 is manually driven. The pull member 113 drives the mounting plate 110 to move through the second connecting rod 112 and the first connecting rod 111. When the mounting plate 110 moves, it pushes the connecting member 105 to move through the pull plate 109. When the connecting member 105 moves, it drives the lever 107 to move through the limiting groove 106. The lever 107 drives the rotating shaft 102 to rotate through the connecting plate 108, thereby causing the heat insulation plate 101 to rotate, thus opening the protective tube 100.

[0091] As the first connecting rod 111 moves, it drives the rotating disk 209 to rotate via the pull rope 211. The rotating disk 209 drives the guide protrusion 210 to rotate. The guide protrusion 210 pushes against the guide member 208 to raise the stop rod 207. When the protective tube 100 is opened, the stop rod 207 disengages from the piston 203. At this time, the piston 203 moves under the action of the first spring 205, thereby compressing the hot air inside the protective tube 100 and causing it to escape from the heat insulation plate 101.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
