When a small amount of water flows into the interior of the screen casing 61, the water accumulates on the pressure assembly 62 forming an enclosed area, and the baffle 67 is also closed, thereby achieving a double closure and increasing the screening time for the water flow. When the water flow is too large or the water is too much accumulated, the pressure assembly 62 rotates to contract inwards around the bent rod 66, the spoiler 67 expands outwards around the bent rod 66 to release the sealing effect, the pressure assembly 62 presses the expansion ball 65, the expansion ball 65 contracts continuously and pulls the contraction rope 64, the furling scale 63 fixed at the other end of the contraction rope 64 moves along the inner wall of the pressure assembly 62 in the direction of the expansion ball 65, the furling scale 63 connected with the contraction rope 64 is the farthest piece from the expansion ball 65, and the furling scales 63 are connected in a stacked manner by the contraction rope 64, so that the furling scale 63 is pulled by the contraction rope 64 to form a whole piece
When water flow normally flows into the sieving and filtering die sleeve 411, water flows spirally along the auger blade 414, the water flow simultaneously contacts the inner wall of the sieving and filtering die sleeve 411 for sieving and filtering and adheres the adhering column 413 to impurities in the water, wherein the auger blade 414 is used for increasing the contact area between the water flow and the sieving and filtering die sleeve 411 so as to increase the sieving and filtering effect on water quality, when the water flow is too large, the water extrudes the auger blade 414 so that the auger blade 414 forms a compression state along the adhering column 413, therefore, the connecting plate 415 fixed at the lower half section of the auger blade 414 drives the flowing base 416 to move downwards, the flowing base 416 and the upper surface of the perforated plate 422 form a folding trend, thereby reducing the water flow flowing out from the sieving and filtering die sleeve 411 and the adhering column 413, increasing the contact time between the water flow and the sieving and filtering die sleeve 411 and the adhering column 413, wherein the adsorption sponge 424 fixed on the upper surface of the opening plate 422 not only plays a role of adsorbing impurities in water, but also plays a role of leaving a thread gap for water to pass when the circulation base 416 and the opening plate 422 are folded, thereby preventing water flow from blocking and accumulating, when the water flow is overloaded, the circulation base 416 can extrude the adsorption sponge 424, so that the adsorption sponge 424 shrinks and extrudes the opening plate 422, at this time, the opening plate 422 can move downwards along the outer wall of the screening mold sleeve 411 and the inner wall of the pressure relief groove 423, so that a part of the water in the screening mold sleeve 411 flows into the pressure relief groove 423 from the upper surface of the opening plate 422 and flows into the pressure relief groove 423 from the pressure relief holes 421 formed on the surface of the opening plate 422, thereby achieving the pressure relief effect, wherein the openings among the opening plate 422, the screening mold sleeve 411 and the pressure relief groove 423 are always kept closed.
When water normally flows into the inner sliding sleeve 51, the water flows in from the inlet of the vertical pipe 54, then flows out from the outlet and enters the inside of the sliding shell 59, wherein the movable plate 53 and the inner sliding sleeve 51 are sealed, and then enters the next device, when the water flow is too large or the water flow injection speed is higher than the water flow speed from the vertical pipe 54, the movable plate 53 moves downwards along the sliding rod 58 and finally is abutted against the blocking ring 57, then a gap is formed between the movable plate 53 and the inner sliding sleeve 51, so that the water flow passes through, so as to achieve the pressure relief effect, when the water flow is overloaded, the movable plate 53 and the blocking ring 57 carry the inner sliding sleeve 51 to move downwards on the inner wall of the sliding shell 59, when the inner sliding sleeve 51 slides to the lowest end of the sliding shell 59, then the inner sliding sleeve 51 drives the sliding shell 59 to move downwards, so that the extrusion plate 56 fixed at the bottom of the sliding shell 59 continuously breaks through the blocking ring 55 to achieve the effect of increasing the gap for allowing more water flow to pass, wherein the height of the inner sliding sleeve 51 is higher than the sliding shell 59, and the other sliding shell 52 is in a closed state of limiting flow between the sliding shell 59.
When a small amount of water flows into the interior of the screen casing 61, the water accumulates on the pressure assembly 62 forming an enclosed area, and the baffle 67 is also closed, thereby achieving a double closure and increasing the screening time for the water flow. When the water flow is too large or the water is too much accumulated, the pressure assembly 62 rotates by contracting inwards around the bent rod 66, the spoiler 67 expands outwards around the bent rod 66 to release the closing effect, the pressure assembly 62 presses the expansion ball 65, so that the expansion ball 65 continuously contracts and pulls the contraction rope 64, the furling scale 63 fixed at the other end of the contraction rope 64 moves along the inner wall of the pressure assembly 62 in the direction of the expansion ball 65, wherein the furling scale 63 connected with the contraction rope 64 is the farthest piece from the expansion ball 65, and because the furling scales 63 are connected in a stacked manner, the furling scale 63 is pulled by the contraction rope 64 to form a whole piece to achieve the water flow circulation effect.
