Description

Technical Field

[0001] This utility model relates to the field of valve plate technology, specifically to a high-temperature resistant valve plate structure. Background Technology

[0002] Valve plates are typically made of metal or engineering plastics and are disc-shaped or semi-circular in design. The valve plate is fixed to the axial center of the valve body by the valve stem and rotates around the valve shaft to achieve opening and closing control. Alternatively, the valve stem may pass through the valve plate and be linked with the drive shaft to complete the action. The rotation angle controls the cross-sectional area of ​​the medium flow, thereby achieving the cutting off, throttling, or full opening of the pipeline fluid.

[0003] In traditional technology, valve plates need to withstand the impact of water flow, so multiple sets of steel mesh are designed inside them to improve overall strength. However, multiple sets of steel mesh increase production costs and weight. In addition, valve plates encounter a lot of heat when they are working to discharge flue gas, which can cause the valve plates to deform and reduce sealing performance.

[0004] Therefore, it is particularly important to improve the existing high-temperature resistant valve plate structure, design a new high-temperature resistant valve plate structure to solve the above-mentioned technical defects, and improve the overall practicality of the high-temperature resistant valve plate structure. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature resistant valve plate structure. When using the high-temperature resistant valve plate structure, the amount of steel reinforcement is reduced through the design of the honeycomb plate, and the cooling pipe is designed to effectively cool the valve plate, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-temperature resistant valve plate structure includes a valve plate, a sleeve fixedly connected to the middle of the valve plate, an insertion hole inside the sleeve, a receiving groove inside the valve plate, the sleeve dividing the receiving groove into two equal groups, a cooling tube fixedly connected to the receiving groove, the cooling tube having a multi-group stacked structure design, a reinforcing ring fixedly connected to the edge of the valve plate, the reinforcing ring extending to the outside of the valve plate, a fixing ring fixedly connected to the outside of the sleeve, reinforcing strips fixedly connected to both ends of the fixing ring, and the reinforcing plate extending to both sides of the valve plate.

[0008] As a preferred embodiment of this utility model, honeycomb plates are fixedly connected to both sides of the receiving groove, and an expansion space is formed between the honeycomb plates and the receiving groove.

[0009] As a preferred embodiment of this utility model, one end of the cooling tube extends to the outside of the valve plate, and a sealing block is inserted and connected to the end of the cooling tube near the valve plate.

[0010] As a preferred embodiment of this utility model, a sealing ring is fixedly connected to the outside of the sealing block, and a sealing groove is provided on the inner wall of the cooling pipe at a position corresponding to the sealing ring.

[0011] As a preferred embodiment of this utility model, auxiliary holes are symmetrically provided at both ends of the socket, and the interiors of the auxiliary holes and the socket are interconnected.

[0012] As a preferred embodiment of this utility model, the valve plate is composed of a conductive plate and a heat-resistant plate on both sides. The conductive plate is located on the inner side of the valve plate and close to the honeycomb plate, while the heat-resistant plate is located on the side of the conductive plate away from the honeycomb plate.

[0013] As a preferred embodiment of this utility model, a groove is formed between the conductive plate and the heat-resistant plate, and a heat-conducting block is fixedly connected to the side of the conductive plate that is close to the heat-resistant plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the sleeve protrudes outside the valve plate, and the streamlined protrusion design reduces turbulence. Combined with the optimized valve plate angle, it can reduce pressure drop and increase flow coefficient, making it suitable for high flow rate scenarios. At the same time, the design of the fixing ring and reinforcing strip distributes the force to the outside of the valve plate, thereby protecting both sides of the valve plate. The reinforcing strip can effectively resist the deformation of the valve plate caused by the impact of high pressure fluid by increasing the overall rigidity of the valve plate. The honeycomb plate design, with a hollow center, reduces the amount of steel reinforcement used. At the same time, the expansion space between the honeycomb plate and the receiving groove can provide the valve plate with a certain amount of expansion, preventing the valve plate from cracking when heated and expanding, thus extending the service life of the valve plate.

[0016] 2. By filling the cooling tube with refrigerant, inserting a sealing block into the cooling tube, and inserting a sealing ring into the sealing groove, a closed area is formed inside the cooling tube. The cooling tube is circulated by coolant, which cools the valve plate. When the heat conduction plate experiences high temperature, it conducts heat from the heat-resistant plate to the heat conduction block, which then dissipates heat outward, thereby improving the high temperature resistance of the valve plate body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0024] A high-temperature resistant valve plate structure includes a valve plate 1. A sleeve 2 is fixedly connected to the middle of the valve plate 1. The sleeve 2 has an insertion hole 3 inside. A receiving groove 4 is formed inside the valve plate 1. The sleeve 2 divides the receiving groove 4 into two groups of equal size. Cooling tubes 5 are fixedly connected to the receiving groove 4. The cooling tubes 5 are designed with a multi-group stacked structure. A reinforcing ring 6 is fixedly connected to the edge of the valve plate 1. The reinforcing ring 6 extends to the outside of the valve plate 1. A fixing ring 7 is fixedly connected to the outside of the sleeve 2. Reinforcing strips 8 are fixedly connected to both ends of the fixing ring 7. The reinforcing strips 8 extend to both sides of the valve plate 1. By inserting a rotating shaft into the insertion hole... The internal structure of sleeve 3 allows valve plate 1 to be installed. The protrusion of sleeve 2 is on the outside of valve plate 1. The streamlined protrusion design reduces turbulence. Combined with the optimized angle of valve plate 1, it can reduce pressure drop and increase flow coefficient, making it suitable for high flow rate scenarios. At the same time, the design of fixing ring 7 and reinforcing strip 8 distributes the force on the outside of valve plate 1, thereby protecting both sides of valve plate 1. Reinforcing strip 8 can effectively resist the deformation of valve plate 1 caused by high pressure fluid impact by increasing the overall rigidity of valve plate 1. Under high temperature and high pressure or frequent opening and closing conditions, reinforcing strip 8 reduces the generation of fatigue cracks in valve plate 1 by dispersing stress concentration, significantly improving wear resistance.

[0025] Furthermore, in this embodiment, honeycomb plates 9 are fixedly connected to both sides of the receiving groove 4, and an expansion space is formed between the honeycomb plates 9 and the receiving groove 4. In order to improve the overall strength, the traditional valve plate 1 is filled with multiple sets of steel bars to form a steel mesh. However, the design of the honeycomb plate 9 is hollow in the middle, which reduces the amount of steel bars used. At the same time, the expansion space between the honeycomb plate 9 and the receiving groove 4 can give the valve plate 1 a certain amount of expansion, prevent the valve plate 1 from cracking when it is heated and expanded, and extend the service life of the valve plate 1.

[0026] Furthermore, in this embodiment, one end of the cooling pipe 5 extends to the outside of the valve plate 1, and a sealing block 10 is inserted and connected to the end of the cooling pipe 5 near the valve plate 1. A sealing ring 11 is fixedly connected to the outside of the sealing block 10. A sealing groove is opened on the inner wall of the cooling pipe 5 at a position corresponding to the sealing ring 11. By filling the inside of the cooling pipe 5 with refrigerant, and then inserting the sealing block 10 into the inside of the cooling pipe 5, while the sealing ring 11 is inserted into the sealing groove, a closed area is formed inside the cooling pipe 5. The cooling pipe 5 is then circulated by the coolant, and the valve plate 1 is cooled.

[0027] Furthermore, in this embodiment, auxiliary holes 12 are symmetrically provided at both ends of the insertion hole 3. The internal parts of the auxiliary holes 12 and the insertion hole 3 are interconnected. By providing auxiliary holes 12, the insertion shaft is inserted into the internal part of the insertion hole 3. An auxiliary block is provided at the position corresponding to the auxiliary hole 12 to increase the contact point with the auxiliary hole 12 when the insertion shaft rotates, thus preventing the shaft from slipping when rotating.

[0028] Furthermore, in this embodiment, the valve plate 1 is composed of a conductive plate 101 and a heat-resistant plate 102 on both sides. The conductive plate 101 is located on the inner side of the valve plate 1 and close to the honeycomb plate 9, while the heat-resistant plate 102 is located on the side of the conductive plate 101 away from the honeycomb plate 9. A slot is formed between the conductive plate 101 and the heat-resistant plate 102. A heat-conducting block 103 is fixedly connected to the side of the conductive plate 101 and the heat-resistant plate 102 that are close to each other. When the conductive plate 101 is subjected to high temperature, it conducts heat from the heat-resistant plate 102 to the heat-conducting block 103. The heat-conducting block 103 then dissipates heat outward, thereby improving the high temperature resistance of the valve plate body 1.

[0029] In this embodiment, the specific implementation scenario is as follows: by inserting the rotating shaft into the interior of the insertion hole 3 and setting an auxiliary block at the position corresponding to the auxiliary hole 12, the contact point between the shaft and the auxiliary hole 12 is increased when the shaft rotates, preventing the shaft from slipping during rotation. The sleeve 2 protrudes outside the valve plate 1, and the streamlined protrusion design reduces turbulence. Combined with the optimized angle of the valve plate 1, it can reduce pressure drop and increase the flow coefficient, making it suitable for high-flow-rate scenarios. At the same time, the design of the fixing ring 7 and the reinforcing strip 8 distributes the force on the outside of the valve plate 1, thereby protecting both sides of the valve plate 1. The reinforcing strip 8 can effectively resist the deformation of the valve plate 1 caused by the impact of high-pressure fluid by increasing the overall rigidity of the valve plate 1. Under high temperature and high pressure or frequent opening and closing conditions, the reinforcing strip 8 reduces the fatigue of the valve plate 1 by dispersing stress concentration. The formation of cracks significantly improves wear resistance. The design of the honeycomb panel 9, with its hollow center, reduces the amount of steel reinforcement used. At the same time, the expansion space between the honeycomb panel 9 and the receiving groove 4 provides a certain amount of expansion for the valve plate 1, preventing cracking of the valve plate 1 when heated and extending its service life. By filling the cooling pipe 5 with refrigerant and then inserting the sealing block 10 into the cooling pipe 5, while the sealing ring 11 is inserted into the sealing groove, a closed area is formed inside the cooling pipe 5. The cooling pipe 5 is circulated by coolant, which cools the valve plate 1. When the heat conduction plate 101 experiences high temperatures, it conducts heat from the heat-resistant plate 102 to the heat conduction block 103, which then dissipates heat outward, thereby improving the high-temperature resistance of the valve plate body 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
