[0014] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0015] The first embodiment of the present application is as follows:

[0016] Please refer to Figure 1 , wherein, Figure 1 is the overall structural schematic diagram of the penetrating hydraulic pulp gate valve of the first embodiment of the present utility model. The present utility model provides a penetrating hydraulic pulp gate valve, including a valve body 1, a sealing ring 2, a gate plate 3, a polyurethane rectangular ring 4, a gland 5, a support rod 6, a link rod 7 and a hydraulic device 8; through the foregoing solution, the problems of the traditional penetrating hydraulic pulp gate valve being not wear-resistant, not erosion-resistant, easy to leak, and having poor product sealing performance during the opening and closing processes are solved.

[0017] For this specific embodiment, the valve body 1 provides support for the device. The sealing ring 2 is fixedly connected to the inner wall of the valve body 1 and is located inside the valve body 1. The gate plate 3 is slidably connected to the valve body 1 and is located outside the sealing ring 2. The polyurethane rectangular ring 4 is fixedly connected to the valve body 1 and is located outside the valve body 1. The valve body 1 provides support and sealing for the device. One side of the sealing ring 2 abuts against the inner wall of the valve body 1, and the other side abuts against the plane of the gate plate 3. Under the pressure in the valve cavity inside the valve body 1, the sealing ring 2 is more closely attached to both sides of the valve body 1, making the sealing ring 2 more favorably abut against the outside, preventing the medium from leaking out, thereby improving the service life of the valve and enhancing the sealing stability at the same time. The gate plate 3 adopts a penetrating gate plate, which hinders the overflowing medium of the valve and prevents the sealing surface from being damaged caused by the eddy current phenomenon.

[0018] Among them, the lower end of the valve body 1 has no obstruction, and the impurities in the pulp flow out through the channel of the gate plate 3 while the gate plate 3 opens and closes. The material of the sealing ring 2 adopts a polyether type wear-resistant material. The valve body 1 with no obstruction at the lower end can effectively reduce the generation of slag accumulation phenomenon and increase the overall service life of the valve body 1.

[0019] Secondly, the gland 5 is fixedly connected to the valve body 1 and is located above the polyurethane rectangular ring 4. The pressing plate cooperates with the stuffing box inside the valve body 1. At the same time, the pressing plate realizes sliding sealing with the gate plate 3, preventing the medium from leaking out and significantly enhancing the durability.

[0020] Thirdly, the support rod 6 is slidably connected to the valve body 1 and is located above the gland 5. The support rod 6 provides support for the hydraulic device 8.

[0021] Finally, the connecting rod 7 is fixedly connected to the gate plate 3 and is located inside the gate plate 3. The hydraulic device 8 is fixedly connected to the support rod 6 and is located at the top of the support rod 6. The connecting rod 7 is used to control the gate plate 3. The hydraulic device 8 is convenient for forming an overall hydraulic control with the hydraulic station. Driving the connecting rod 7 to rise or fall through the hydraulic device 8 is convenient for controlling the gate plate 3. It can visually determine whether the valve is in the open or closed state. When the gate plate 3 is exposed at the lower end, it is in the open state. When the gate plate 3 is exposed at the upper end, the valve is in the closed state.

[0022] Using the penetrating hydraulic pulp gate valve of this embodiment, the valve body 1 provides support and sealing functions for the device. One side of the sealing ring 2 abuts against the inner wall of the valve body 1, and the other side closely abuts against the plane of the gate plate 3. Under the pressure in the valve cavity inside the valve body 1, the sealing ring 2 is more closely abutted against both sides of the valve body 1, making the sealing ring 2 more favorably abut outwards, so that the medium will not leak out, thereby improving the service life of the valve and at the same time improving the stability of the seal. The gate plate 3 adopts a penetrating gate plate, which plays a role in obstructing the overflowing medium of the valve and preventing the damage of the sealing surface caused by the eddy current phenomenon, solving the problems of the traditional penetrating hydraulic pulp gate valve being not wear-resistant, not erosion-resistant, easy to leak, and having poor product sealing performance during the opening and closing processes.

Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
