Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a novel high-temperature resistant flat gate valve. Background Technology

[0002] Flat gate valves, as key components for controlling the opening and closing and regulating of media in industrial pipeline systems, are widely used in many fields such as petroleum, natural gas, and chemical industries due to their advantages such as low flow resistance and good sealing performance. However, in some special operating conditions, such as steam transportation in high-temperature environments and pipeline connections in high-temperature chemical reaction devices, ordinary flat gate valves cannot withstand the high temperatures and are prone to problems such as sealing failure and component deformation and damage. Therefore, high-temperature resistant flat gate valves have emerged. The manufacturing of new high-temperature resistant flat gate valves requires comprehensive consideration of factors such as material selection, structural optimization, and cooling and heat dissipation. The aim is to improve the stability, reliability, and service life of flat gate valves in high-temperature environments by adopting special high-temperature resistant materials, innovative sealing structures, and efficient cooling technologies.

[0003] Currently, new high-temperature resistant flat gate valves on the market exhibit various technical types. Some products use high-temperature resistant alloy materials to manufacture the valve body, gate, and seat, such as nickel-based alloys and chromium-molybdenum alloy steel, to enhance the components' resistance to high-temperature deformation and corrosion. However, these products lack heat dissipation for the valve body itself, making it difficult to cool down when the temperature is too high. Furthermore, the valve plate expands when the temperature is too high, leading to severe wear during sliding. Therefore, a new type of high-temperature resistant flat gate valve is proposed to solve these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a novel high-temperature resistant flat gate valve, which aims to improve the existing technology by addressing the lack of cooling for the gate valve body and the problem of wear caused by the valve plate expanding due to excessive temperature.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel high-temperature resistant flat gate valve includes a body, an internally threaded screw, an internally fixed transmission pipe, an internally disposed valve plate, an internally disposed cooling assembly, and an internally disposed connecting assembly. The cooling assembly includes a heat dissipation ring and heat dissipation fins. The inner wall of the heat dissipation ring is fixedly connected to the internal wall of the body, the inner wall of the heat dissipation fins is fixedly connected to the internal wall of the body, a fixed plate is fixedly connected to the internal wall of the body, a sliding plate is slidably connected between the internal wall of the body and the side wall of the fixed plate, a spring is disposed between the internal wall of the body and the side wall of the fixed plate, one end of the spring is fixedly connected to the internal wall of the body, the other end of the spring is fixedly connected to the side wall of the sliding plate, and a limit plate is fixedly connected to the side wall of the sliding plate.

[0007] As a further description of the above technical solution:

[0008] The connecting assembly includes a connecting pipe and an input pipe. The inner wall of the connecting pipe is fixedly connected to the side wall of the transmission pipe. The input pipe is disposed on the side wall of the connecting pipe. An insertion pipe is fixedly connected inside the input pipe. The side wall of the insertion pipe is slidably connected to the inner wall of the connecting pipe.

[0009] As a further description of the above technical solution:

[0010] The side wall of the limiting plate is slidably connected to the inner wall of the machine body, and the side wall of the valve plate is slidably connected to the side wall of the limiting plate.

[0011] As a further description of the above technical solution:

[0012] A receiving ring is fixedly connected to the side wall of the transmission pipe, and the side wall of the valve plate is slidably connected to the side wall of the receiving ring.

[0013] As a further description of the above technical solution:

[0014] A protective frame is fixedly connected to the side wall of the machine body, and an air inlet is provided inside the protective frame.

[0015] As a further description of the above technical solution:

[0016] One end of the screw is fixedly connected to a turntable, and the other end of the screw is fixedly connected to a connecting rod. The side wall of the connecting rod is rotatably connected to the inside of the valve plate.

[0017] As a further description of the above technical solution:

[0018] The connecting pipe and the input pipe are both fixedly connected to a sliding block, and the connecting pipe and the input pipe are both fixedly connected to a fixing block, with the inner wall of the fixing block slidably connected to the side wall.

[0019] As a further description of the above technical solution:

[0020] Both the connecting pipe and the input pipe are fixedly connected to a sealing ring one, and both the transmission pipe and the insertion pipe are fixedly connected to a sealing ring two.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the temperature of the gate valve under high-temperature conditions is reduced by each set of heat dissipation rings, which prevents the performance of components from deteriorating due to excessive temperature, extends the service life of the gate valve, and ensures its normal operation in high-temperature environments. The limit plate is adjustable by springs to prevent the valve plate from thermally expanding when the temperature is too high, which would cause severe wear during sliding. This solves the problem of traditional flat gate valves lacking heat dissipation components, which leads to the deterioration of the material performance of components such as the body and valve plate, sealing failure or deformation when the temperature is too high, thus improving the stability of the equipment.

[0023] 2. In this utility model, the connecting pipe and the input pipe constitute the main body of the connecting component, which is used to connect the transmission pipe with other pipes or equipment, expand the medium transmission path, and quickly connect the transmission pipe to the input pipe through the connection of the fixed block and the sliding block, effectively reducing the docking time. The sealing effect is achieved through multiple sealing rings, which solves the problem that traditional flat gate valves require multiple sets of bolts for fixing, which results in long connection time and high manpower consumption, and improves the efficiency and convenience of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] reference Figures 1-5An embodiment of this utility model is provided: a novel high-temperature resistant flat gate valve, including a body 1, a screw 9 threadedly connected inside the body 1, a transmission pipe 11 fixedly connected inside the body 1, a valve plate 13 inside the body 1, a cooling component on the side wall of the body 1, and a connecting component on the side wall of the screw 9.The cooling assembly includes a heat dissipation ring 7 and a heat dissipation fin 8. The inner wall of the heat dissipation ring 7 is fixedly connected to the side wall of the body 1, and the side wall of the heat dissipation fin 8 is fixedly connected to the side wall of the body 1. The heat dissipation ring 7 and the heat dissipation fin 8 work together to increase the heat dissipation area and accelerate the heat dissipation speed, so as to dissipate the heat generated during the operation of the gate valve to the surrounding environment in a timely manner, improve the heat dissipation efficiency, and enhance the high temperature resistance of the gate valve. A fixing plate 14 is fixedly connected to the inner wall of the body 1. The fixing plate 14 provides an installation and support base for components such as the sliding plate 15. A sliding plate 15 is slidably connected between the inner wall of the body 1 and the side wall of the fixing plate 14. The sliding plate 15 can slide flexibly between the fixing plate 14 and the inner wall of the body 1, and plays an auxiliary guiding role when the valve plate 13 is actuated. The sliding plate 15 serves to limit and stabilize the valve plate 13, ensuring smooth lifting and lowering and preventing expansion due to excessive temperature, which could lead to displacement or jamming. A spring 17 is installed between the inner wall of the body 1 and the side wall of the fixed plate 14. One end of the spring 17 is fixedly connected to the inner wall of the body 1, and the other end is fixedly connected to the side wall of the sliding plate 15. The spring 17 provides elastic force to the sliding plate 15, acting as a buffer and reset mechanism during the lifting and lowering of the valve plate 13, reducing the impact and vibration on the internal structure of the gate valve, and ensuring that the sliding plate 15 can be reset in time to maintain the normal working state of the gate valve. A limit plate 10 is fixedly connected to the side wall of the sliding plate 15, and the side wall of the limit plate 10 is slidably connected to the inner wall of the body 1. The side wall of valve plate 13 is slidably connected to the side wall of limit plate 10. Limit plate 10 is connected to sliding plate 15, which restricts the movement range of valve plate 13, preventing valve plate 13 from deviating and damaging the internal structure of the gate valve. At the same time, it provides sealing assistance when valve plate 13 is closed, enhancing the sealing performance of the gate valve. A receiving ring 12 is fixedly connected to the side wall of transmission pipe 11. The side wall of valve plate 13 is slidably connected to the side wall of receiving ring 12. Receiving ring 12 provides support and guidance for valve plate 13. When valve plate 13 is closed, it fits tightly with valve plate 13, enhancing the sealing performance. At the same time, it shares the medium pressure on valve plate 13, ensuring uniform force on valve plate 13 and extending the service life of valve plate 13. A protective frame 2 is fixedly connected to the side wall of body 1 to prevent... The protective frame 2 protects the gate valve exterior and heat dissipation components, while also providing some safety protection for operators, preventing burns from accidental contact with the high-temperature gate valve. An air inlet 6 is provided inside the protective frame 2, allowing air to enter and promote air convection, aiding the heat dissipation ring 7 and heat sink 8 in heat dissipation, further reducing the gate valve surface temperature and enhancing its heat dissipation effect and high-temperature resistance. A turntable 5 is fixedly connected to one end of the screw 9, and a connecting rod 16 is fixedly connected to the other end. The side wall of the connecting rod 16 is rotatably connected inside the valve plate 13. The turntable 5 provides a point of leverage for the operator to manually rotate the screw 9, thus opening and closing the valve plate 13.

[0034] Reference Figures 1-3 and Figure 6The connecting assembly includes a coupling pipe 4 and an input pipe 3. The inner wall of the coupling pipe 4 is fixedly connected to the side wall of the transmission pipe 11 to ensure the sealing of the connection, prevent media leakage, and ensure the safety and stability of media transmission. The input pipe 3 is located on the side wall of the coupling pipe 4 and can be connected to other pipes for quick docking. An insertion pipe 18 is fixedly connected inside the input pipe 3. The side wall of the insertion pipe 18 is slidably connected to the inner wall of the coupling pipe 4. The insertion pipe 3 enhances the tightness and stability of the connection between the input pipe 18 and the coupling pipe 4. After being inserted into the coupling pipe 4, it can increase the connection area and improve the connection strength, ensuring that the connection will not loosen under the action of media pressure, thus ensuring the safety of media transmission. Sliding blocks 19 are fixedly connected to the side walls of both the coupling pipe 4 and the input pipe 3, and fixing blocks 20 are fixedly connected to the side walls of both the coupling pipe 4 and the input pipe 3. The inner wall of the fixing block 20 is slidably connected to the side wall of the sliding block 19. When the input pipe 3 and the connecting pipe 4 are connected in place, the fixed block 20 can be fixed to prevent the input pipe 3 from sliding under the action of medium pressure or external force, ensuring the stability of the connection and the normal transmission of the medium. By rotating the input pipe 3, the fixed block 20 can be inserted into the sliding block 19 to achieve quick docking. Both the connecting pipe 4 and the side wall of the input pipe 3 are fixedly connected with sealing ring 11. Sealing ring 11 can effectively fill the gap between the connecting pipe 4 and the input pipe 3, enhance the sealing performance of the connection, prevent the medium from leaking from the connection, and ensure the sealing and safety of the medium transmission process. Both the transmission pipe 11 and the insertion pipe 18 are fixedly connected with sealing ring 22. Sealing ring 22 further strengthens the sealing effect between the transmission pipe 11 and the insertion pipe 18, preventing the medium from leaking when the medium passes through the connection and ensuring that the medium is transmitted along the predetermined path.

[0035] Working principle: Rotating the turntable 5 drives the screw 9 to rotate. Since the screw 9 is threadedly connected to the inside of the machine body 1, it moves axially when rotating, which in turn pushes the valve plate 13 to move through the connecting rod 16. Under the guidance and support of the limiting plate 10 and the receiving ring 12, the valve plate 13 achieves smooth sliding. When the valve plate 13 completely blocks the passage of the transmission pipe 11, the valve is closed, blocking the flow of the medium. When the valve plate 13 is moved away, the valve opens, and the medium can pass smoothly through the transmission pipe 11. The heat dissipation ring 7 and heat dissipation fins 8 in the cooling component increase the heat dissipation area of ​​the machine body 1 and accelerate the diffusion of heat to the outside. The air inlet 6 on the protective frame 2 promotes air circulation and further improves the heat dissipation effect. When the valve plate 13 is closed, the valve plate 13 pushes the sliding plate 15 to compress the spring 17, making the sliding plate 15 fit more tightly against the inner wall of the body 1. The elasticity of the spring 17 enhances the sealing between the valve plate 13 and the limiting plate 10. At the same time, it reduces the limiting effect of the valve plate 13 when it expands due to high temperature. In the closed state, it assists in heat insulation. In the connection assembly, the insertion tube 18 on the input pipe 3 can be slidably inserted into the connecting pipe 4 to achieve quick docking. Then, by twisting the input pipe 3, the fixing block 20 is locked into the sliding block 19, ensuring the stability of the pipeline during docking and preventing misalignment. Through the sealing ring 21 and sealing ring 22 on the side walls of the connecting pipe 4, input pipe 3, transmission pipe 11 and insertion tube 18, a multi-seal structure is formed to ensure the sealing of the connection and prevent medium leakage. At the same time, it avoids the loss of heat from the connection of the high-temperature medium and maintains the overall high-temperature resistance of the valve.
