The cleaning assembly also includes a stop collar 204; the guide ring 203 is made of elastic material; each guide ring 203 is fixedly connected with a limiting ring 204, and the limiting rings 204 are fixedly connected with the ropes 201. The cleaning assembly further includes a spring 205, a connecting plate 206, and a magnet 207; each circular ring 101 is provided with an annular groove 101a; a plurality of springs 205 are fixedly connected in each annular groove 101a; all springs 205 positioned on the same circular ring 101 are fixedly connected with a connecting plate 206 made of magnetic materials, the connecting plate 206 is in sliding connection with the corresponding circular ring 101, and one side of the connecting plate 206 far away from the butterfly plate 4 is an N pole; two magnets 207 distributed left and right are fixedly connected to the valve body 1, and one side of the magnets 207, which is close to the butterfly plate 4, is an N pole.
The impurity in the liquid material also can be stained with and attach on the valve body 1 inner wall, long-term not clear up can lead to valve body 1 inner wall to receive the corruption, when need carry out periodic cleaning to valve body 1 inner wall, rotate butterfly plate 4 earlier and reset and close valve body 1, at this moment, the outside pipeline at valve body 1 both ends is short temporarily not to lead to the material, then, the manual work pulls rope 201 and rolls, rope 201 pulls ring 101 to keeping away from one side of butterfly plate 4 and remove, ring 101 breaks away from each other with butterfly plate 4, elastic cord 202 takes place adaptive deformation and is stretched, until ring 101 moves valve body 1 tip, and then ring 101 strikes off the impurity that the valve body 1 inner wall is stained with, avoid adhering in valve body 1, lead to valve body 1 to be corroded.
Along with the ring 101 continuously scrapes the impurity of valve body 1 inner wall, scrape the impurity of falling and gather in the lower part side of ring 101 under the action of gravity, when the impurity of ring 101 lower part gathering is more and more, when the high more ring 101 of gathering impurity, ring 101 can leak partial impurity when removing for ring 101 can not push away valve body 1 with whole impurity, at this moment, it is spacing to carry out the water conservancy diversion to the impurity of gathering, avoid impurity to leak when exceeding ring 101, lead to scraping the in-process, the impurity of scraping on ring 101 upper portion can drop back valve body 1 inner wall downwards, can not be pushed away by ring 101, reduce impurity scraping efficiency, at this moment, carry out spacingly through spacing ring 204 to the impurity that water conservancy diversion ring 203 dropped, make the impurity flow down to ring 101 lower part along water conservancy diversion ring 203, avoid the impurity to drop back valve body 1 inner wall.
In the initial state that the ring 101 contacts with the butterfly plate 4, the guide ring 203 made of elastic materials contracts, so that the obstruction to the flow of materials is avoided when the butterfly plate 4 is opened, when the rope 201 pulls the ring 101 to move, the limiting ring 204 is pulled by the rope 201, the limiting ring 204 stretches the guide ring 203, and the guide ring 203 pulls the ring 101 to move to scrape the inner wall of the valve body 1, as shown in fig. 9 and 10.
However, as the ring 101 continuously moves to scrape the inner wall of the valve body 1, more and more impurities are accumulated on one side, away from the butterfly plate 4, of the ring 101, so that the accumulated impurities can cross the ring 101, and cannot be pushed away from the inner wall of the valve body 1 by the ring 101, and further the scraping efficiency is reduced, therefore, when the ring 101 moves, as one side, away from the butterfly plate 4, of the connecting plate 206 is an N pole, and one side, close to the butterfly plate 4, of the magnet 207 is an N pole, so that the connecting plate 206 and the magnet 207 repel each other, as the distance between the connecting plate 206 and the magnet 207 is gradually increased, the spring 205 is compressed, and as the connecting plate 206 and the magnet 207 are gradually closed, until the connecting plate 206 enters the bottom of the annular groove 101a, the spring 205 is compressed to the limit, so that the annular groove 101a is exposed, and then the accumulated impurities temporarily enter the annular groove 101a, thereby increasing the amount of the impurities pushed away by the ring 101, and improving the scraping efficiency, and normally, the connecting plate 206 seals the annular groove 101a under the action of the elasticity of the spring 205, and prevents materials from entering the annular groove 101 a.

On the basis of the embodiment 2, as shown in fig. 3 and 11, a storage hopper 208 and a telescopic plate 209 are further included; the valve body 1 is detachably connected with two storage hoppers 208 distributed left and right; each storage hopper 208 is fixedly connected with a telescopic plate 209, and the telescopic end of the telescopic plate 209 is in sliding connection with the storage hopper 208; the telescopic end of each telescopic plate 209 is fixedly connected with two convex blocks 209a respectively; one side of each rope 201 close to the limiting ring 204 is provided with a convex rod 201a, and the convex rods 201a are matched with the convex blocks 209 a.
The outside of the storage bucket 208 is provided with a rubber paste, so that the tightness between the storage bucket 208 and the valve body 1 is enhanced, and leakage of materials from a gap between the storage bucket 208 and the valve body 1 is avoided.
When the rope 201 pulls the circular ring 101 to move to the end part of the valve body 1, the rope 201 drives the convex rod 201a to extrude the convex rod 209a, so that the convex rod 209a compresses the telescopic plate 209, the telescopic plate 209 opens the bucket opening of the storage bucket 208, the circular ring 101 pushes scraped impurities into the storage bucket 208 for temporary storage, the storage bucket 208 is manually taken out when the valve body 1 is not used, impurities in the storage bucket 208 are cleaned, and under the normal condition that the circular ring 101 does not clean impurities on the inner wall of the valve body 1, the bucket opening of the storage bucket 208 is closed by the telescopic plate 209, so that materials are prevented from entering the storage bucket 208.
