Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment
Embodiment 1.As shown in Figure 1, comprise valve body 1 and valve gap 2, in the left and right sides, lower end of valve body 1, be respectively equipped with water intake 3 and water outlet 4, guiding valve 5 and valve body inner sleeve 6 are housed in 1; On valve body 1 top, lifting gear 7 and tightening sleeve 8 are housed, on tightening sleeve 8, are provided with groove 9; Guide rod 10 and thrust spring 11 are housed on lifting gear 7, guide rod 10 connecting grooves 9.Lifting gear 7 essence are cam mechanisms, produce vertical-lift power when it horizontally rotates.In the utility model, be that the interior motion of the groove on tightening sleeve 89 realizes this function by guide rod 10.For reducing tripping force, groove 9 is designed to L shaped, is totally divided into two sections, and the first half section gradient of groove 9 is less, milder, and the second half section gradient is larger, steeper.The lower end of lifting gear 7 connects guiding valve 5 by connection set 12.For strengthening sealing, prevent that tap water is penetrated into other cavity by the gap between guiding valve 5 and valve body inner sleeve 6 and water intake 3 and water outlet 4 blocking-up mouths, between valve body 1 and valve body inner sleeve 6, and between valve body 1 and guiding valve 5,4 seal rings 13 between guiding valve 5 and valve body inner sleeve 6, have been used, and in valve body inner sleeve 6, be provided with guiding gutter 14, one end of guiding gutter 14 is communicated with valve body 1 inner chamber, and the other end of guiding gutter 14 is equipped with intumescent seal ring 15.It is advantageous that:, when cutting off the water, intumescent seal ring 15 is not subject to the effect of hydraulic pressure, and its pressure less (during relative sliding, frictional force is less) that guiding valve 5 is produced now contributes to the return of guiding valve 5; Send after water recovering, this intumescent seal ring 15 inwardly shrinks the Water Pressure that is subject to coming via guiding gutter 14, and itself and the pressure of guiding valve 5 are increased, and contributes to enhancing sealing effect now.Guiding valve 5 can overcome under the frictional force that comes from intumescent seal ring 15 and slides to limit inferior position when guaranteeing to cut off the water, and need to consider that the weight design of guiding valve 5 and the design of Expansion sealing circle 15 guarantee.For strengthening the iris action of guiding valve 5, permanent magnet 16 is also housed on valve body 1.For guaranteeing to recover to send after water, water intake 3 and water outlet 4 can not linked up by guiding valve 5 and the gap of valve body 1, by the seal ring 13 between valve body 1 and guiding valve 5, guarantee on the one hand, mouth is blocked in another aspect pressure (be the weight of guiding valve 5, the active force of magnet 16, tap water to guiding valve 5 upper-end surface pressure) by increasing by 5 pairs, guiding valve guarantees.
