Second cranks arm 4 is articulated on valve gap 1 by the second rotatingshaft 41, the second rotatingshaft 41 crank arm second 4 divide into long-armed 411 with galianconism 412; First 3 fixed ends of cranking arm are articulated on valve gap 1, and the first 3 free ends and second, 4 galianconism 412 of cranking arm of cranking arm are slidably connected, and long-armed 411 turn back makes the first 3 and second 4 formation of cranking arm of cranking arm have the semi-closed ring of opening, and this semi-closed ring is encircled in valve gap 1 surrounding.
The present invention also discloses a kind of inlet valve, comprise valve gap 1, waterstop pad 2, first crank arm 3, second crank arm 4, valve body 5, controlling rod 6, keg float 7 and keg float water tank 8.
Form intake tunnel in valve body 5, the feed-water end of intake tunnel is connected with water pipe, and waterexit end is cistern water supply; Valve gap 1 is arranged in valve body 5, forms water-inlet cavity 51 with valve body 5, forms the sealing face 53 with water inlet 52, as shown in Figure 5 in water-inlet cavity 51.Water-inlet cavity 51 feed-water end communicates with intake tunnel, and water-inlet cavity 51 waterexit end communicates with exhalant canal.
Valve gap 1 being installed waterstop pad 2 is positioned on sealing face 53, waterstop pad 2 is arranged water passage hole 21, forms back pressure cavity 22 between waterstop pad 2 and valve gap 1; Valve gap forms back pressure hole, and back pressure hole is communicated with back pressure cavity 22 with outside.
Second cranks arm 4 by being articulated on valve gap 1 perpendicular to the second rotatingshafts 41 of valve gap 1, and valve gap 1 arranges pivot hole 12, and the second rotatingshaft 41 rotates pivot joint in pivot hole 12.Second rotatingshaft 41 crank arm second 4 divide into long-armed 411 with galianconism 412, long-armed 411 ends are free end, first end of cranking arm 3 fixed ends is articulated on valve gap 1 by the first rotatingshaft 31 perpendicular to valve gap 1, valve gap 1 arranges pivot hole 13, and the first rotatingshaft 31 rotates pivot joint in pivot hole 13.First 3 free ends of cranking arm stride across 4 galianconism 412 of cranking arm with second above back pressure hole 11 and are slidably connected, and first cranks arm the 3 settings back pressure pad 311 relative with back pressure hole 11 position.
Long-armed 411 free ends are connected with the controlling rod 6 be arranged on keg float 7, and keg float 7 is placed in keg float water tank 8, and keg float water tank 8 is arranged on valve body 5.
Inlet valve back pressure hole of the present invention is closed opening device and is arranged in the water-inlet cavity 51 of valve body 5, make inlet valve back pressure hole close opening device assembling and dismounting and change more convenient, and overall volume is less.
In the present embodiment, second crank arm 4 free end card column 43 is set, controlling rod 6 upper end arranges draw-in groove 61, card column 43 insert in draw-in groove 61 with controlling rod 6 interlock, make to remove and install payment convenient.
In the present embodiment, at water-inlet cavity 51 sidewall of valve body 5, at least two limit ribs 54 are set, as shown in Fig. 6 and Fig. 8, corresponding setting at least two spacing card articles 15 on valve gap 1 outer side wall, valve gap 1 is placed in the water-inlet cavity 51 of valve body 5, the spacing card article of valve gap 1 15 against spacing on the limit ribs 54 of water-inlet cavity 51 limiting valve cap 1 come off.
As shown in Figures 3 and 4, when concrete installation valve gap 1, the spacing card article 15 of valve gap 1 is staggered with the limit ribs 54 of water-inlet cavity 51, and be placed in water-inlet cavity 51, now, second card column 43 of 4 free ends of cranking arm is separated with the draw-in groove 61 of controlling rod 6, then rotary valve cover 1 makes the spacing card article of valve gap 1 15 against spacing on the limit ribs 54 of water-inlet cavity 51, the spacing card article 15 of valve gap 1 is positioned at inner side, and the limit ribs 54 of water-inlet cavity 51 is positioned at outside, during valve gap 1 Horizontal displacement, limit ribs 54 stops spacing its Horizontal displacement of card article 15 of valve gap, and then limiting valve cap 1 comes off.Now, the second card column 43 of cranking arm 4 free ends insert in the draw-in groove 61 of controlling rod 6 with controlling rod 6 interlock.
During use, as shown in FIG. 6 and 7, when keg float water tank 8 water level decreasing, keg float 7 gravitate and thereupon declining, drives controlling rod 6 to decline, and drives second to crank arm 4 toward lower swing, order about first to crank arm and 3 to swing away from back pressure hole 11, make back pressure pad open back pressure hole 11, water enters in water tank through valve body 5 intake tunnel, realizes water inlet.
As can be seen from figures 8 and 9, after keg float water tank 8 water level rises, keg float 7 rises by floating function thereupon, controlling rod 6 is driven to decline, drive second to crank arm 4 up to swing, order about first and crank arm and 3 to swing near back pressure hole 11, make back pressure pad again close back pressure hole 11, waterstop pad 2 produces counterpressure and is out of shape the water inlet 52 sealed on sealing face 53, realizes stopping water inlet.
The foregoing is only the preferred embodiments of the present invention, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
