The utility model discloses a use method as follows:

when the flap filter is closed, the cylinder 3 drives the first connecting rod 4 to move, then the first connecting rod 4 drives the second connecting rod 7 to move rightwards through the V-shaped connecting rod 6, so that the second connecting rod 7 pulls the backwashing valve plate 8 rightwards through the third hinge seat 15, at the same time, the backwashing valve plate 8 presses the rubber gasket 14 tightly on the inner wall on the left side of the water outlet 2 to form a seal, meanwhile, the inner wall of the rubber sleeve 13 is attached to the outer wall of the limiting pipe 12, the outer peripheral surface of the rubber sleeve 13 is attached to the inner wall of the sealing hole 11, the existence of the rubber sleeve 13 can form a seal, so that a double-sealing effect is realized, even if the water flow in the pool body breaks through the seal of the rubber sleeve 13 rightwards, the rubber gasket 14 still has a sealing effect, the water pressure in the pressurizing groove 18 is continuously increased, and finally, when the water flow breaks through the seal of the rubber sleeve 13 rightwards, a part of the water flow enters the pressurizing groove 18, and the outer peripheral surface of the pressurizing groove 13 is further weakened, and the sealing groove 18 is further weakened, even if the sealing effect of the sealing of the rubber sleeve 13 is further weakened, the sealing of the sealing hole is increased, the sealing is further increased, the sealing of the sealing groove 13, and the sealing groove 13, the sealing groove 13 is further increased, the sealing groove 13, even if the sealing groove 13 is further increased, the sealing effect of the sealing groove 13 is generated, the sealing effect of the sealing device is always ensured.

When the elasticity of pressure boost spring 25 was applied to pressure boost plate 23 on, pressure boost plate 23 then can extrude rubber pad 14 left, made the left side lateral wall of rubber pad 14 further laminate on delivery port left side inner wall, further improved the sealed effect of rubber pad 14, even rubber pad 14 appears not hard up because self elasticity weakening the condition, pressure boost spring 25's elasticity then can compensate rubber pad 14's elasticity, made rubber pad 14 left side lateral wall laminate on 2 left side inner walls of delivery port all the time, effectively guaranteed the leakproofness of delivery port 2 positions.

To sum up, can know, the utility model discloses accessible rubber sleeve 13 forms double containment with rubber pad 14, and rubber sleeve 13 then can guarantee the sealed effect of self all the time through interior seal structure, and rubber pad 14 then can guarantee the sealed effect of self all the time through external seal structure to guarantee the leakproofness of delivery port 2 positions all the time, effectively avoid sealed inefficacy to lead to rivers to turn over the board filtering pond seepage to the outer condition of delivery port when closing the valve, thereby effectively stop the filter material along with the condition of rivers loss.

Be equipped with in the pressure-increasing groove 18 rather than assorted thimble 19, thimble 19 left end face is equipped with one and is annular intake chamber 20, intake chamber 20 link up with inlet opening 17 mutually, thimble 19 outer wall all is equipped with a plurality of holes of exerting pressure 21 that link up mutually with intake chamber 20 with the inner wall, thimble 19's existence can play the effect of supporting the rubber sleeve 13 left part, avoid behind the rubber sleeve 13 left end face be equipped with pressure-increasing groove 18 along with the reduction of material lead to the not good unable and spacing pipe 12 outer wall of elasticity of itself, the condition that the inner wall of seal hole 11 closely laminates, and intake chamber 20 still has the expanded effect when can making the rubber sleeve 13 left part obtain the support with the existence in hole 21 of exerting pressure.

11 right-hand member drill way in sealed hole is equipped with one and is annular sealed breach 26, sealed breach 26's diameter is decreased progressively from the right side to the left side, if rivers pass through 13 outer peripheral faces of rubber sleeve and 11 inner walls of sealed hole seepage to sealed breach 26 position, because sealed breach 26 at this moment, 13 outer peripheral faces of rubber sleeve and 14 left side lateral walls of rubber pad enclose to close and form an inclosed space, consequently the rivers of seepage to sealed breach 26 position then can directly get into to inclosed space in, the rivers of seepage just can continue towards 14 leakages of rubber pad until being full of whole inclosed space, sealed breach 26's existence can effectively delay leakage efficiency, if just a small amount of seepage, sealed breach 26 is enough to hold the rivers of seepage, make rivers can not continue the seepage to the right side.

Because backwash valve plate 8 is when opening and close with the swing of second articulated seat 9 as the center, consequently rubber sleeve 13 is not straight to penetrate to sealed hole 11, and in sealed hole 11 is gone into to sealed hole 11 through sealed hole 11 right-hand member port card with the form of swing, the existence of sealed breach 26 can also play the guide effect to the rubber sleeve of cover outside spacing pipe 12, not only can not receive the hindrance when making rubber sleeve 13 swing card go into, and can follow sealed breach 26 quick and accurate card go into to sealed hole 11.

1 right side inner wall of pool body is equipped with one with the coaxial swing hole 10 of delivery port 2, the existence in swing hole 10 not only can guarantee that second connecting rod 7 has sufficient swing space when swinging, and swing hole 10 is the narrow hourglass hopper-shaped in the wide right side in a left side, rivers when in the pool body flow to the inlet opening 17 in through swing hole 10, swing hole 10 can carry out the pressure boost to the rivers through the aperture that self constantly narrows, thereby increase rivers and carry out the degree to pressure boost groove 18 inner wall, make rubber sleeve 13 further expand, further improve rubber sleeve 13's sealed effect.

The groove bottom of the annular groove 22 is provided with a condensing groove 27, the left side wall of the pressure increasing plate 23 is provided with a condensing protrusion 28 matched with the condensing groove 27, the outer wall of the condensing protrusion 28 is attached to the inner wall of the condensing groove 27, when the pressure increasing plate 23 presses the groove bottom of the annular groove 22 to the left, the condensing protrusion 28 presses the groove bottom of the condensing groove 27 to the left, the groove width of the condensing groove 27 is gradually decreased from the right to the left, therefore, the pressure of the condensing protrusion 28 is condensed at the groove bottom of the condensing groove 27 to form a linear ring shape, it is ensured that the left side wall of the rubber pad 14 is provided with the annular protrusion generated by the pressure action to enclose and seal the orifice at the right end of the sealing hole 11, and the sealing effect of the rubber pad 14 is ensured to the maximum extent.
