Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and more specifically, it relates to a water-cooled valve plate for a slide gate valve. Background Technology

[0002] Currently, the water-cooled valve plate is a crucial component of water-cooled slide gate valves. The water-cooled valve plate has several cooling water channels, through which circulating water can circulate, thus cooling the valve plate.

[0003] Chinese patent CN221482700U discloses a valve plate structure for a water-cooled slag valve. It mainly features multiple water-cooling channels and connected return water channels within the valve plate body, and a return water connector on the valve plate body. An inlet end cap is bolted to the rear end face of the valve plate body, containing a main inlet pipe and connected branch inlet pipes. An inlet connector is also located on the inlet end cap. The inlet and return water connectors are connected to a power plant water treatment system via pipelines, providing circulating demineralized water to the valve plate body for water cooling. Therefore, the water-cooled valve plate structure designed in this invention, by providing circulating demineralized water to the valve plate body for water cooling, avoids valve plate deformation due to high temperatures, preventing incomplete closure and ensuring the normal operation of the shut-off valve.

[0004] While this type of valve can achieve water cooling, the following issues exist: the multiple water inlet branches are vertically distributed, and during the water cooling process, the uneven distribution causes localized overheating of the valve plate. Furthermore, the internal water flow path cannot achieve uniformity, resulting in flow imbalance, which affects the cooling effect and fails to guarantee the overall temperature balance of the valve. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water-cooled valve plate for a slide gate valve, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled valve plate for a slide gate valve, comprising a circulating water connector, on which a valve plate is installed and sealed. Symmetrical cooling channels are provided within the circulating water connector, one of which is an inlet and the other an outlet. An inlet channel is provided within the valve plate, connecting to the cooling channel of the inlet. An outlet channel is provided above the inlet channel, connecting to the cooling channel of the outlet. The inlet and outlet channels are connected via an outer ring channel, which is divided into two sections: an inlet section and an outlet section. Both the inlet and outlet sections are independently connected to a transition channel group located inside the valve plate.

[0007] As an optional solution of this utility model, one side of the transition channel assembly is sealed by a cover plate, which is used to seal the outer ring channel and the transition channel assembly.

[0008] As an optional solution of this utility model, a water inlet seal plate is installed on the inlet channel.

[0009] As an optional solution of this utility model, a water outlet sealing plate is installed on the water outlet channel.

[0010] As an optional embodiment of this utility model, the transition channel group includes a first transition channel, one side of which is connected to an outer ring channel, a second transition channel is connected inside the first transition channel, a third transition channel is connected inside the second transition channel, a fourth transition channel is connected inside the third transition channel, and a central slot is connected inside the fourth transition channel.

[0011] As an optional solution of this utility model, the first transition channel, the second transition channel, the third transition channel and the fourth transition channel are all annular, and a cross-shaped stirring blade is installed and sealed in the centralized tank. The cross-shaped stirring blade can rotate freely through a rotating shaft.

[0012] This utility model provides a water-cooled valve plate for a slide gate valve, which has the following beneficial effects:

[0013] The entire system enters the valve plate's inlet channel through the cooling channel within the circulating water connector. Cooling begins along the outer ring channel. By setting up a transition channel group, the liquid can be guided into the first transition channel, then into the second, third, and fourth transition channels, and finally into the collection tank. The fluid dynamics drive the cross-shaped stirring blades to rotate, further cooling the liquid before it flows back into the outer ring channel. This rapid cooling and even distribution of the water flow ensures the overall temperature balance of the valve plate. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a water-cooled valve plate 2 for a slide gate valve, including a circulating water connector 1, on which the valve plate 2 is installed and sealed. Symmetrical cooling channels 101 are provided inside the circulating water connector 1, one cooling channel 101 being an inlet and the other a outlet. An inlet channel 201 is provided inside the valve plate 2, connecting to the cooling channel 101 at the inlet. An outlet channel 203 is provided above the inlet channel 201, connecting to the cooling channel 101 at the outlet. The inlet channel 201 and the outlet channel 203 are connected. The flow channel 203 is connected to the outer ring flow channel 202, thus enabling unidirectional flow. The outer ring flow channel 202 is divided into two sections: an inlet section and an outlet section. Both the inlet and outlet sections are independently connected to a transition flow channel group. The transition flow channel group is located inside the valve plate 2, and one side is sealed by a cover plate 6. The cover plate 6 is used to seal the outer ring flow channel 202 and the transition flow channel group. An inlet sealing plate 3 is installed on the inlet flow channel 201, and an outlet sealing plate 4 is installed on the outlet flow channel. The inlet sealing plate 3 and the outlet sealing plate 4 can be disassembled and cleaned to ensure internal cooling flow and prevent blockage.

[0024] The transition channel group includes a first transition channel 204, one side of which is connected to an outer ring channel 202. A second transition channel 205 is connected inside the first transition channel 204. A third transition channel 206 is connected inside the second transition channel 205. A fourth transition channel 207 is connected inside the third transition channel 206. A concentrator 208 is connected inside the fourth transition channel 207. Each of the first, second, third, and fourth transition channels 204, 205, 206, and 207 has two independent channels, one for water inlet and one for water outlet, to achieve single-direction flow, avoid local overheating, and ensure balanced flow. A sealed cross-shaped stirring blade 209 is installed inside the concentrator 208. The cross-shaped stirring blade 209 rotates freely via a shaft. When liquid enters the first transition channel 204 and reaches the concentrator 208, it is mixed and cooled by the rotation of the cross-shaped stirring blade 209 before finally flowing into the outer ring channel 202 for further cooling.

[0025] The specific usage and function of this embodiment are as follows: First, after water is supplied to the circulating water connector 1, it enters the inlet channel 201 and begins to be transported for cooling along the outer ring channel 202. The outer ring channel 202 is divided into an inlet section and an outlet section, which are independently distinguished. The water enters the first transition channel 204 through the inlet section of the outer ring channel 202, and then enters the first section of the second transition channel 205, the first section of the third transition channel 206, and the first section of the fourth transition channel 207 along the first section of the first transition channel 204. Finally, it enters the collection tank 208, where the cross-shaped stirring blade 209 is driven to rotate by the flow force for further cooling. Finally, it flows into the second section of the fourth transition channel 207 and flows out sequentially until it reaches the outlet section of the outer ring channel 202, thereby rapidly cooling down. Finally, it is discharged from the outlet channel 203. If the cooling is slow, the inlet sealing plate 3, the outlet sealing plate 4, and the cover plate 6 are disassembled and cleaned to ensure smooth cooling flow.
