Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, shown in Figure 15.

The valve of energy automatic cut-off, by: ball float 1, upper valve body 2, following valve body 3, valve plate 4, sealing gasket 5, backguy screw rod 6, spring 7, rotating shaft 8, rope or chain 9 are formed.

The valve of a kind of energy automatic cut-off, comprise: ball float 1, upper valve body 2, following valve body 3, valve plate 4, upper valve body 2 is connected and fixed with following valve body 3, in the formed cavity valve plate 4 is installed between upper valve body 2 and the following valve body 3, valve plate 4 is connected with the inwall of following valve body 3, sealing gasket 5, backguy screw rod 6 are installed on the valve plate 4, ball float 1 is connected with valve plate 4 with backguy screw rod 6 by rope or chain 9, when valve plate 4 under the effect of ball float 1 during throttle down, valve plate 4 is closed fully with the intake-outlet 21 of upper valve body 2.

Upper valve body 2 is a pipe joint formula structure, and following valve body 3 is a telescoping structure, and upper valve body 2 is tightened and is fixed on down on the valve body 3, and upper valve body 2 and following valve body 3 constitute the valve body structure of valves.

Valve plate 4 is a disc-shaped structure, backguy screw rod 6 is twisted in being pressed on the valve plate 4 on the valve plate 4 and with sealing gasket 5, valve plate 4 is connected with following valve body 3 by rotating shaft 8, install and spring 7 in the rotating shaft 8, spring 7 is the button spring structure, and valve plate 4 can be along rotating shaft 8 rotations and on the inwall of being close to following valve body 3 under the effect of spring 7.

The size of ball float 1 volume should be able to make buoyancy that ball float 1 the produced gravity sum greater than resistance and valve plate 4, rope or the chain 9 of spring 7 in water.

As shown in Figure 3, be installed on valve that can automatic cut-off on the water tank 10 or approach on the pipeline of water tank 10, then rope or chain 9 are coupled together with ball float 1, the length of rope or chain 9 is decided by the height of liquid 11 liquid levels in the water tank 10, when the liquid level of liquid 11 in the water tank 10 reaches the extreme higher position, the length of rope or chain 9 should make ball float 1 can strain valve 4, and valve plate 4 can so just have been finished installment work substantially with the intake-outlet 21 complete seal closures of upper valve body 2.

When water tank 10 is empty when not having water to intake, at this moment ball float 1 is positioned at the bottom position of water tank 10, valve plate 4 and on sealing gasket 5, backguy screw rod 6 is at spring 7, under the effect of rotating shaft 8, valve plate 4 is close on the inwall of following valve body 3, liquid passes through valve body 3 down, upper valve body 2 enters in the water tank 10, rising along with liquid level in the water tank 10, ball float 1 is also along with rising, when the liquid level in the water tank 10 arrives higher liquid level, ball float 1 spurs valve plate 4 gradually by rope or chain 9 and upwards rotates, and along with the continuation of liquid level is risen and closed the intake-outlet 21 of upper valve body 2 gradually, when liquid level reached the highest liquid level or required liquid level, ball float 1 was moved valve plate 4 extreme higher position to and with intake-outlet 21 complete closed of upper valve body 2, has so just been blocked further water inlet automatically by rope or chain 9, at this moment, valve plate 4 under the effect of the pulling force of ball float 1 and intake pressure, valve plate 4 sealing intake-outlets 21, the sealing gasket 5 on the valve plate 4 plays seal action, prevent to leak, close inlet valve then and get final product.

In the time will making water, as long as open outlet valve or water tap, then water will flow out automatically, valve plate 4 can be opened under the effect of spring 7, and water will flow out from water tank 10, along with the increase of water flow, liquid level descends in the water tank 10, then ball float 1 also descends, and valve plate 4 can be opened bigger and bigger, and current will constantly flow out.

When needing to intake again in the water tank 10, as long as repeat above-mentioned steps.So just can realize well that convenient and reliable road turnover supplied water.
