Description

Technical Field

[0001] This utility model relates to the field of ultra-high temperature hot water equipment, specifically a hot water equipment with a temperature exceeding 100 degrees Celsius. Background Technology

[0002] In industrial production, scientific research experiments, and centralized heating systems, hot water exceeding 100°C is frequently required to meet specific thermal energy demands. From the perspective of heat density and transfer efficiency, hot water at higher temperatures has a larger heat energy storage capacity, and its heat transfer efficiency is improved due to the greater temperature difference between the hot water and the object being heated. Regarding specific process temperature thresholds, high-temperature sterilization in disinfection requires ultra-high temperatures, and many other industrial processes, such as chemical reactions and food processing, also have corresponding high-temperature requirements.

[0003] Pressurized high-temperature hot water boilers increase the boiling point of water by increasing the internal pressure through a sealed container (e.g., the boiling point of water is about 184℃ at 1MPa pressure). The equipment is equipped with a pressure control system, safety valve, and temperature sensor to ensure stable heating under high pressure. It has a large heating power and a temperature controllable range of 100-180℃, making it suitable for scenarios requiring high-temperature heat sources.

[0004] However, this equipment is in a high temperature and high pressure state for a long time, and the sealing gasket of its water inlet is prone to damage due to thermal expansion and contraction, resulting in leakage. This causes the medium loss rate and maintenance cost to increase dramatically. Therefore, a high temperature hot water equipment exceeding 100 degrees Celsius is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-temperature hot water device exceeding 100 degrees Celsius to solve the technical problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature hot water device, comprising a device body, an inlet pipe fixedly connected to the outer wall of the device body, a pipe cover rotatably installed on the top of the inlet pipe, and a compression ring fixedly connected to the inner side of the pipe cover;

[0007] A second sealing ring is fixedly installed on the inner side of the pipe cover, and a first sealing ring corresponding to the second sealing ring is fixedly installed on the top of the water inlet pipe to form a fitting seal.

[0008] An annular bracket is fixedly installed on the inner wall of the water inlet pipe, and a piston device is fixedly installed on the annular bracket. A movable ring is fixedly connected to the end of the piston device, and the inside of the piston device is a liquid medium that expands and contracts with temperature changes, used to push and pull the movable ring. A rubber ring is fixedly installed on the outer wall of the movable ring. When the piston device pushes the movable ring, the rubber ring abuts against the compression ring and deforms, which is used to further seal the water inlet pipe.

[0009] By adopting the above technical solution, and by setting a No. 1 sealing ring and a No. 2 sealing ring to fit together, when the pipe cover is closed, the two are squeezed against each other and deformed to fill the gap, thus achieving a basic seal. This method is more effective than the traditional method of sealing by the flat contact of the sealing rings and can extend the service life of the sealing rings. At the same time, the thermal expansion and contraction of the medium is used to drive the piston device and the moving ring. When the equipment is heated, the medium expands, causing the moving ring to move the rubber ring and be squeezed by the compression ring to deform, thereby filling the gap, thus further improving the sealing performance and significantly improving the sealing reliability and safety of the water inlet pipe.

[0010] Furthermore, the water inlet pipe includes a connecting flange, which is located at the top of the water inlet pipe, and the connecting flange and the side of the pipe cover are provided with latches for locking the water inlet pipe.

[0011] By adopting the above technical solution, and by setting a latch on the side of the mating flange and the pipe cover, when locked, the latch will tightly fasten the pipe cover to the mating flange, thereby providing initial mechanical clamping force, which, together with the sealing ring, achieves a seal.

[0012] Furthermore, the piston device is provided in multiple sets on the annular support. The piston device includes a piston cylinder and a piston rod. The outer wall of the piston cylinder is fixed to the annular support, and the inside of the piston cylinder is a liquid medium that expands and contracts with temperature. The piston rod is nested inside the piston cylinder, and the end of the movable ring is connected to the end of the piston rod.

[0013] By adopting the above technical solution, the piston device generates a uniform and symmetrical pushing and pulling force on the moving ring, thereby avoiding local stress concentration and effectively preventing the rubber ring from failing to seal properly due to uneven force.

[0014] Furthermore, multiple sets of guide rods are fixedly connected to the annular bracket, and the guide rods are threaded onto the movable ring, with the end diameter of the guide rod being larger than the diameter of the rod body.

[0015] By adopting the above technical solution, the moving path of the movable ring is guided by the guide rod, and slippage caused by excessive displacement of the movable ring is avoided.

[0016] Furthermore, the adjacent sides of the extrusion ring and the rubber ring are designed with corresponding arc-shaped bevels, and the side of the rubber ring does not adhere to the inner wall of the water inlet pipe.

[0017] By adopting the above technical solution, when the movable ring drives the rubber ring to move, the corresponding arc-shaped inclined surfaces of the two cause the rubber ring to be guided and squeezed to deform, thereby vertically filling the gap between the connecting flange and the No. 2 sealing ring, achieving the effect of strengthening the sealing performance.

[0018] Furthermore, the plane where the top surface of the movable ring is located is lower than the plane where the bottom surface of the extrusion ring is located, and the positions of the movable ring and the extrusion ring are staggered. When the movable ring moves and crosses and fits against the extrusion ring, the movable ring and the extrusion ring restrict each other's displacement.

[0019] By adopting the above technical solution, the cross-cooperation of the compression ring and the moving ring can strengthen the connection between the pipe cover and the mating flange, and greatly improve the locking and sealing effect.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention significantly improves the sealing reliability and safety of the inlet pipe through the collaborative design of multiple structures. By incorporating a first and second sealing ring that interlock, the two rings deform and fill gaps when the pipe cover is closed, achieving a basic seal. Simultaneously, the thermal expansion and contraction of the medium drives the piston rod and movable ring. When the equipment heats up, the medium expands, causing the rubber ring to move and deform under the pressure of the compression ring, further filling gaps and enhancing sealing performance. The cross-operation of the compression ring and movable ring strengthens the connection between the pipe cover and the flange, significantly improving the locking and sealing effect. When the equipment temperature decreases, the negative pressure generated by the medium contraction pulls the movable ring back to its original position, without affecting the normal opening and closing of the pipe cover, and relieving the pressure on the rubber ring, allowing it to return to its initial shape for repeated sealing enhancement upon subsequent heating.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1

[0031] A hot water device with a temperature exceeding 100 degrees Celsius, such as Figure 1-5 As shown, the device includes a main body 1, an inlet pipe 2 is fixedly connected to the outer wall of the main body 1, and a pipe cover 3 is rotatably installed on the top of the inlet pipe 2, and a compression ring 32 is fixedly connected to the inner side of the pipe cover 3.

[0032] A second sealing ring 33 is fixedly installed on the inner side of the pipe cover 3, and a first sealing ring 22 corresponding to the second sealing ring 33 is fixedly installed on the top of the water inlet pipe 2 to form a fitting seal. By setting the first sealing ring 22 and the second sealing ring 33 to fit together, when the pipe cover 3 is closed, the two are squeezed against each other to deform and fill the gap, thereby achieving a basic seal. This method is more effective than the traditional method of sealing by the flat contact of the sealing rings and can extend the service life of the sealing rings.

[0033] An annular bracket 4 is fixedly installed on the inner wall of the water inlet pipe 2, and a piston device is fixedly installed on the annular bracket 4. A movable ring 43 is fixedly connected to the end of the piston device, and the inside of the piston device is a liquid medium that expands and contracts with temperature changes, used to push and pull the movable ring 43. A rubber ring 431 is fixedly installed on the outer wall of the movable ring 43. When the piston device pushes the movable ring 43, the rubber ring 431 abuts against the compression ring 32 and deforms, which is used to further seal the water inlet pipe 2. By using the thermal expansion and contraction of the medium to drive the piston device and the movable ring 43, when the equipment is heated, the medium expands and causes the movable ring 43 to move, and is deformed by the compression ring 32, thereby filling the gaps, thus further improving the sealing performance and significantly improving the sealing reliability and safety of the water inlet pipe 2.

[0034] Please see Figure 1-5 The inlet pipe 2 includes a connecting flange 21, which is located at the top of the inlet pipe 2. The connecting flange 21 and the pipe cover 3 are provided with a locking buckle 31 on their sides for locking the inlet pipe 2. By providing the locking buckle 31 on the connecting flange 21 and the pipe cover 3, when locked, the locking buckle 31 will tightly fasten the pipe cover 3 to the connecting flange 21, thereby providing an initial mechanical clamping force, which, together with the sealing ring, achieves a seal.

[0035] Please see Figure 1-5The piston device has multiple sets on the annular support 4, which makes the piston device generate a uniform and symmetrical pushing and pulling force on the movable ring 43, thereby avoiding local stress concentration and effectively preventing the rubber ring 431 from failing to seal properly due to uneven force. The piston device includes a piston cylinder 42 and a piston rod 421. The outer wall of the piston cylinder 42 is fixed to the annular support 4, and the inside of the piston cylinder 42 is a liquid medium that expands and contracts with temperature. The piston rod 421 is nested in the piston cylinder 42, and the end of the movable ring 43 is connected to the end of the piston rod 421. When the equipment temperature drops, the negative pressure generated by the contraction of the medium can pull the movable ring 43 to reset, which does not affect the normal opening and closing of the pipe cover 3, and can relieve the pressure state of the rubber ring 431, allowing it to return to its initial shape so that the sealing enhancement can be repeated when the temperature rises again.

[0036] Please see Figure 1-5 Multiple sets of guide rods 41 are fixedly connected to the annular bracket 4, and the guide rods 41 are mounted on the movable ring 43. The diameter of the end of the guide rod 41 is larger than the diameter of the rod body. The guide rods 41 guide the movement path of the movable ring 43 and prevent the movable ring 43 from slipping due to excessive displacement.

[0037] Please see Figure 1-5 The extrusion ring 32 and the rubber ring 431 are adjacent to each other with corresponding arc-shaped inclined surfaces. When the movable ring 43 drives the rubber ring 431 to move, the corresponding arc-shaped inclined surfaces guide and compress the rubber ring 431 to deform, thereby vertically filling the gap between the connecting flange 21 and the second sealing ring 33, achieving the effect of strengthening the sealing performance. Moreover, the side of the rubber ring 431 does not adhere to the inner wall of the water inlet pipe 2, thus providing space for the deformation of the rubber ring 431.

[0038] Please see Figure 1-5 The plane on which the top surface of the movable ring 43 is located is lower than the plane on which the bottom surface of the compression ring 32 is located, and the positions of the movable ring 43 and the compression ring 32 are staggered. When the movable ring 43 moves and crosses and fits with the compression ring 32, the movable ring 43 and the compression ring 32 restrict each other's displacement. Through the cross cooperation of the compression ring 32 and the movable ring 43, the connection tightness between the pipe cover 3 and the docking flange 21 can be strengthened, and the locking and sealing effect can be greatly improved.

[0039] The working principle of this utility model is as follows: after the main body 1 of the equipment has completed the water intake, the pipe cover 3 is closed and locked and fixed by the buckle 31. At this time, the first sealing ring 22 and the second sealing ring 33 form an interlocking connection, which enhances the sealing performance of the water inlet pipe 2.

[0040] When the main body 1 of the equipment is in a heated state, as the temperature rises, the medium in the piston cylinder 42 absorbs heat, the temperature rises, and the volume expands. Since the internal space of the piston cylinder 42 is limited and it is fixed by the annular support 4, the expanding medium pushes the piston to move towards the open end, thereby driving the piston rod 421 to extend and output thrust to the movable ring 43, causing the movable ring 43 to move forward. At the same time, the guide rod 41 guides the movement path of the movable ring 43 and prevents the movable ring 43 from slipping due to excessive displacement.

[0041] As the movable ring 43 moves forward, the rubber ring 431 moves forward accordingly and is deformed by the guidance and compression of the arc-shaped inclined surface of the compression ring 32. At the same time, it fits into the connection gap between the second sealing ring 33 and the mating flange 21 to complete a further seal. At this time, the end of the movable ring 43 and the compression ring 32 form a cross fit, restricting each other's movement, making the connection between the water inlet pipe 2 and the pipe cover 3 more secure. This prevents accidental opening of the pipe cover 3 due to misoperation of the locking buckle 31 or loosening of the locking buckle 31, and further enhances the locking effect of the pipe cover 3 and the locking buckle 31.

[0042] As the temperature of the main body 1 of the equipment gradually decreases, the volume of the medium in the piston cylinder 42 begins to shrink, and a negative pressure is formed in the internal space of the piston cylinder 42, which in turn drives the piston and piston rod 421 to retract to the initial position and pulls the movable ring 43 to reset along the guide rod 41. At the same time, the rubber ring 431 is withdrawn from the side of the compression ring 32 and returns to its initial shape. At this time, the end of the movable ring 43 separates from the compression ring 32 to avoid obstructing the opening and closing of the pipe cover 3.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
