[0032] like Figure 1-Figure 4 As shown, an electric gate valve of the utility model includes a gate valve part and a driving part. The gate valve part includes a valve body 1 and a gate plate 2. A through hole 11 is provided in the valve body 1. The through hole 11 runs through the left and right ends of the valve body 1. The gate plate 2 is used to block the through hole 11. One end of the through hole 11 is a liquid inlet 111, and the other end is a liquid outlet 112. The driving part is used to control the gate plate 2 to move up and down. When working, liquid flows into the valve body 1 from the liquid inlet 111. When the driving part controls the gate plate 2 to move up to release the blockage of the through hole 11, the liquid flows out of the valve body 1 from the liquid outlet 112.

[0033] In this embodiment, a filter screen plate 3 is rotatably provided at one end of the valve body 1 near the liquid inlet 111, the center of the rotating shaft 31 of the filter screen plate 3 is located on a horizontal plane, and the center of the rotating shaft 31 of the filter screen plate 3 intersects and is perpendicular to the axis of the through hole 11, and the side of the filter screen plate 3 away from the liquid inlet 111 abuts against the gate plate 2, and the filter screen plate 3 can block impurities entering the valve body 1 to prevent impurities from being adsorbed on the gate plate 2. When the driving part controls the gate plate 2 to move up and down, it can change the abutment state between the gate plate 2 and the filter screen plate 3, and the filter screen plate 3 is rotated, tilted and vibrated under the impact of the liquid, so that the impurities fall off the filter screen plate 3 and are washed away by the flowing liquid, thereby achieving the purpose of self-cleaning and avoiding the clogging of the filter screen plate 3 after long-term use.

[0034] It should be noted that when the electric gate valve is closed, the gate plate 2 blocks the through hole 11, and the filter screen plate 3 is vertically attached to the side of the gate plate 2 close to the liquid inlet 111, preventing impurities from being adsorbed on the gate plate 2. When the electric gate valve is open, the filter screen plate 3 rotates to an inclined state, and the inclined filter screen plate 3 guides the impurities, and under the impact of the liquid, the impurities pass through the bottom of the through hole 11 along the filter screen plate 3, thereby preventing the impurities from being adsorbed on the gate plate 2.

[0035] In this embodiment, mounting grooves 12 are provided on both sides of the liquid inlet 111, mounting blocks 4 are installed in the two mounting grooves 12, fixing heads 41 are provided on both sides of one end of the mounting block 4, fixing grooves 121 are provided at the ends of the mounting grooves 12, and the fixing heads 41 are fixedly connected in the fixing grooves 121 by hexagon socket bolts. Axle holes 42 are provided at the ends of the two mounting blocks 4, and rotating shafts 31 are provided on both sides of the filter screen 3. The rotating shaft 31 is rotatably installed in the shaft holes 42 to realize the rotational connection between the filter screen 3 and the valve body 1. In some other embodiments, the rotating shaft 31 can also be directly rotatably connected to the inner wall of the through hole 11. In this embodiment, the mounting grooves 12 and the mounting blocks 4 are provided, and after the filter screen 3 is rotatably connected to the two mounting blocks 4, the mounting blocks 4 are fixedly installed in the mounting grooves 12, so as to facilitate the loading and unloading of the filter screen 3.

[0036] In this embodiment, an arc-shaped stopper 5 is provided in the through hole 11, and a chamfer 51 is provided on one side of the arc-shaped stopper 5 close to the liquid inlet 111, so as to facilitate the liquid to flow to the filter screen plate 3. Both mounting blocks 4 are fixedly connected to the arc-shaped stopper 5, and the arc-shaped stopper 5 can be removed synchronously when the mounting blocks 4 are removed. A slide groove 52 is provided on one side of the arc-shaped stopper 5 close to the filter screen plate 3, and the filter screen plate 3 can slide in the slide groove 52, and the arc-shaped stopper 5 is used to block the gap between the upper end of the filter screen plate 3 and the inner wall of the through hole 11. It should be noted that the inner end wall of the slide groove 52 can block the arc-shaped stopper 5, so as to prevent the arc-shaped stopper 5 from flipping over at will in the through hole 11.

[0037] In this embodiment, a first mounting platform 13 is arranged above the middle of the valve body 1, and the driving part includes a second mounting platform 61 and a driving cylinder 62.

The gate plate 2 is slidably inserted in the first slot 131, and the gate plate 2 can slide into the second slot 611. The driving cylinder 62 is fixedly connected to the top of the gate plate 2. A connecting block 21 is fixedly connected to the top of the gate plate 2. A through slot 612 that penetrates the second mounting platform 61 is provided on the inner top wall of the second slot 611. The through slot 612 at the end of the connecting block 21 is fixedly connected to the output shaft of the driving cylinder 62.

[0038] Working principle of the safety valve of this utility model:

[0039] When the electric gate valve is closed, the gate plate 2 blocks the through hole 11 , and the filter screen plate 3 is vertically attached to a side of the gate plate 2 close to the liquid inlet 111 to prevent impurities from being adsorbed on the gate plate 2 .

[0040] When the electric gate valve switches from a closed state to an open state, the output shaft of the driving cylinder 62 drives the gate plate 2 to move upward through the connecting block 21. During the upward movement of the gate plate 2, the gate plate 2 is separated from the obstruction of the filter screen plate 3. After the gate plate 2 is opened, the liquid begins to flow, and the filter screen plate 3 rotates in the slide groove 52 under the impact of the liquid. When the filter screen plate 3 rotates to collide with the inner end wall of the slide groove 52, the filter screen plate 3 vibrates, thereby causing impurities to fall off the filter screen plate 3, and the filter screen plate 3 is in an inclined state at this time. The inclined filter screen plate 3 will guide the impurities, and under the impact of the liquid, the impurities pass through the bottom of the through hole 11 along the filter screen plate 3, thereby preventing the impurities from being adsorbed on the gate plate 2.

[0041] When the electric gate valve switches from an open state to a closed state, the output shaft of the driving cylinder 62 drives the gate plate 2 to move downward through the connecting block 21. During the downward movement of the gate plate 2, the gate plate 2 squeezes the filter screen plate 3 to rotate from an inclined state to a vertical state.

Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
