[0032] As shown in Figure 1 and Figure 2 , the penetrating electric mine pulp gate valve is mainly composed of valve body 1, gate plate 3, electric device, polyurethane rectangular ring 4, Yx sealing ring 2 and other key components.

[0033] Valve body 1 is the main part of the penetrating electric mine pulp gate valve, responsible for accommodating other components and providing fluid passage. The valve body 1 is transversely provided with a channel for the flow of mine pulp, and the gate plate 3 is sealingly installed vertically. The material of the valve body 1 is usually selected to be wear-resistant and corrosion-resistant to withstand the scouring of harsh media such as mine pulp.

[0034] Gate plate 3 is a key component for controlling the opening and closing of fluid. Under the action of the electric device, the gate plate 3 moves up and down in the valve body 1, thereby controlling the opening and closing of the channel. As shown in Figure 3 , the gate plate 3 is provided with a through hole. When the through hole is concentric with the channel, the gate plate 3 is in the open state, allowing fluid to pass through; when the through hole is completely misaligned with the channel, the gate plate 3 is in the closed state, preventing fluid from passing through. During the up and down movement of the gate plate 3, it forms a seal with the polyurethane rectangular ring 4 and the Yx sealing ring 2, ensuring the sealing of the valve.

[0035] The electric device is the power source for driving the gate plate 3 to move up and down. It includes valve stem 7 and electric telescopic mechanism 8. The electric telescopic mechanism 8 is fixed on the valve body 1, usually connected through the bracket 6. One end of the valve stem 7 is fixedly connected with the top of the gate plate 3, and the other end is fixedly connected with the telescopic end of the electric telescopic mechanism 8. When the electric telescopic mechanism 8 telescopes, it drives the gate plate 3 to move up and down through the valve stem 7. The precise control of the electric device ensures the accurate opening and closing of the valve; specifically, the electric telescopic mechanism 8 is an electric push rod.

[0036] The polyurethane rectangular ring 4 is installed in the rectangular grooves at the top and bottom of the valve body 1, and forms a sliding seal with the gate plate 3. The polyurethane rectangular ring 4 has good elasticity, plasticity and wear resistance, and can withstand the friction and extrusion during the up and down movement of the gate plate 3. It is pressed tightly on the valve body 1 by the gland 5, ensuring the close fit between the polyurethane rectangular ring 4 and the gate plate 3, thereby achieving sealing.

[0037] The Yx sealing ring 2 is installed in the outer sealing groove of the channel and forms a seal with the plane of the gate plate 3. The Yx sealing ring 2 is made of polyether wear-resistant material, which has good integrity, elasticity and wear resistance. It can tightly fit on the inner wall of the sealing groove and the plane of the gate plate 3, ensuring the sealing of the valve. At the same time, the design of the Yx sealing ring 2 also considers the effect of guiding slag, avoiding the accumulation of impurities inside the valve.

[0038] In addition to the above key components, the penetrating electric mine pulp gate valve also includes a gland 5, a bracket 6 and other auxiliary components. The gland 5 is used to compress the polyurethane rectangular ring 4, ensuring that it is tightly fitted between the valve body 1 and the gate plate 3. The bracket 6 is used to fix the electric telescopic mechanism 8, ensuring its stable operation. In addition, the inner wall of the valve body 1 and the surface of the gate plate 3 are also coated with a tungsten carbide wear-resistant layer to improve the wear resistance and service life of the valve. The thickness of the tungsten carbide wear-resistant layer is usually between 0.2-0.5mm.

[0039] The working principle of the penetrating electric mine pulp gate valve is relatively simple. When the valve needs to be opened, the electric telescopic mechanism 8 is started, driving the valve stem 7 to move upwards. The valve stem 7 drives the gate plate 3 to move upwards through the fixed connection, making the through hole on the gate plate 3 concentric with the passage of the valve body 1. At this time, the fluid can flow freely through the through hole and the passage. When the valve needs to be closed, the electric telescopic mechanism 8 is started in the opposite direction, driving the valve stem 7 to move downwards. The valve stem 7 drives the gate plate 3 to move downwards through the fixed connection, making the through hole on the gate plate 3 completely misaligned with the passage of the valve body 1. At this time, the fluid is blocked by the gate plate 3 and cannot continue to flow.

[0040] During the opening and closing of the valve, the polyurethane rectangular ring 4 and the Yx sealing ring 2 play a key sealing role. The polyurethane rectangular ring 4 forms a sliding seal between the gate plate 3, ensuring that the gate plate 3 does not leak fluid during upward and downward movement. The Yx sealing ring 2 is tightly fitted on the inner wall of the sealing groove and the plane of the gate plate 3, preventing fluid from leaking from the outside of the passage. At the same time, since the Yx sealing ring 2 is made of polyether type wear-resistant material, it has good wear resistance and can withstand the erosion and friction of the fluid, ensuring the long-term stable operation of the valve.

[0041] In addition, the coating of the tungsten carbide wear-resistant layer also improves the wear resistance of the valve. Under the action of fluid erosion and friction, the tungsten carbide wear-resistant layer can effectively protect the inner wall of the valve body 1 and the surface of the gate plate 3 from damage, prolonging the service life of the valve.

[0042] The penetrating electric mine pulp gate valve has many advantages, making it widely used in industrial applications:

[0043] Strong sealing: The penetrating electric mine pulp gate valve adopts a double sealing structure of polyurethane rectangular ring 4 and Yx sealing ring 2, ensuring the sealing performance of the valve. The polyurethane rectangular ring 4 forms a sliding seal with the gate plate 3, while the Yx sealing ring 2 is tightly fitted on the inner wall of the sealing groove and the plane of the gate plate 3. This double sealing structure can effectively prevent fluid leakage, ensuring the long-term good sealing performance of the valve.

[0044] Wear-resistant and erosion-resistant: The inner wall of the valve body 1 and the surface of the gate plate 3 of the penetrating electric mine pulp gate valve are coated with a tungsten carbide wear-resistant layer, which improves the wear resistance and erosion resistance of the valve. The tungsten carbide wear-resistant layer can withstand the erosion and friction of the fluid, protecting the inner wall of the valve body 1 and the surface of the gate plate 3 from damage. At the same time, the Yx sealing ring 2 is made of polyether wear-resistant material, which also has good wear resistance, ensuring the long-term stable operation of the valve.

[0045] Good slag guiding effect: The gate plate 3 of the penetrating electric mine pulp gate valve adopts a penetrating design, which can avoid the accumulation of impurities during opening and closing. At the same time, the valve body 1 and the Yx sealing ring 2 have sealing grooves in the upper and lower cavities around the valve, and the slag liquid can be directly guided by the channel without accumulation. In this way, the Yx sealing ring 2, the valve body 1 and the penetrating gate plate 3 have a whole slag guiding effect, avoiding the influence of impurities on the sealing performance of the valve.

[0046] High control accuracy: The electric device of the penetrating electric mine pulp gate valve adopts a precise control mechanism, which can ensure the accurate opening and closing of the valve. The electric telescopic mechanism 8 is fixedly connected with the gate plate 3 through the valve stem 7, which can drive the gate plate 3 to move up and down. At the same time, the control system of the electric device can realize precise control of the opening and closing process of the valve, ensuring the stability and reliability of the valve.

[0047] Wide application range: The penetrating electric mine pulp gate valve is suitable for occasions with a nominal diameter of 1200mm or less, especially for pipeline systems conveying harsh media such as mine pulp. Its unique structure and material selection enable it to withstand high pressure, high temperature and harsh media, ensuring long-term stable operation of the valve.

[0048] Visual operation: The gate plate 3 of the penetrating electric mine pulp gate valve moves up and down during opening and closing, exposing or hiding the through hole. This design allows operators to visually determine the opening and closing status of the valve by observing the position of the gate plate 3. This visual operation method improves the convenience and accuracy of operation.

[0049] Remote operation: The electric device of the penetrating electric mine pulp gate valve can be connected with the on-site electric control system to realize remote operation. Operators can open and close the valve in the control room through the control system without manual operation on site. This remote operation method improves work efficiency and safety.

[0050] The penetration electric mine pulp gate valve is a kind of valve product with many advantages. Its unique penetration gate structure, double sealing structure, wear-resistant materials and precise control mechanism design features make it can adapt to the requirements of harsh medium and complex working conditions. In industrial applications, penetration electric mine pulp gate valve has been widely used and achieved good results. In the future, with the continuous development of industrial technology, penetration electric mine pulp gate valve will continue to be improved and perfected, and make greater contribution to the development of industrial field.
