Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of negative pressure speed of the utility model is closed float switch, and it comprises valve body, and described valve body is formed by connecting by upper valve body 2 and following valve body 1, and following valve body 1 and the upper valve body 2 general metallic material that adopt are made, so that bear higher hydraulic pressure.
One end of described valve body forms water inlet A, the other end moulding water inlet 8 and connected osculum 10, and the area of osculum 10 cross sections is greater than the area of water inlet 8 cross sections.The bottom of valve body forms a water outlet B, and the upper end of described water outlet B is provided with seal ring pad 4, also is that water inlet A and water outlet B are isolated mutually by seal ring pad 4.
Described seal ring pad 4 is divided into valve chamber D and the C of lower valve chamber with space in the valve body, the described valve chamber D that goes up is communicated with water inlet A, the described C of lower valve chamber is communicated with water inlet 8, last valve chamber D via through holes 9 is communicated with osculum 10, also promptly goes up valve chamber D via through holes 9, osculum 10 and water inlet 8 and is communicated with the C of lower valve chamber.
Described seal ring pad 4 generally by compression and tensile strength preferably plastic material be made, its middle part is provided with center hole, is provided with epithelium boss circle 11 around the center hole.Pressing plate 3 is located on the seal ring pad 4, pressing plate 3 bottoms are provided with a protuberance 14 and are arranged in the center hole of seal ring pad 4, be provided with a relief hole 7 in the described pressing plate 3, relief hole 7 one ends are located at protuberance 14 places, and the other end is located at the joint place of pressing plate 3 and seal ring pad 4.The area of described relief hole 7 cross sections is less than the area of water inlet 8 cross sections.
Place, described osculum 10 outer ends is provided with a switch controlling device, the ball float 13 that described switch controlling device comprises guide rod 6, is connected in the rubber sleeve 5 of guide rod 6 and is connected in guide rod 6 the other ends, described guide rod 6 is by fixing pin 12 rotatable being located on the valve body, described rubber sleeve 5 is located at osculum 10 outer ends, is provided with Returnning spring between an end of the connection rubber sleeve 5 of described guide rod 6 and the valve body.
Working principle of the present utility model: in the course of the work, if the utility model now has been in closed condition, at this moment, rubber sleeve 5 is under guide rod 6 effects, sealed osculum 10, last valve chamber D, the C of lower valve chamber are communicated with by through hole 9, osculum 10 and water inlet 8, hydraulic pressure is identical, because this moment, the below of seal ring pad 4 and pressing plate 3 was exposed in the outer air of water outlet B, suffered pressure is less than hydraulic pressure, seal ring pad 4, pressing plate 3 top and bottom pressure imbalances under this pressure difference effect, make seal ring pad 4 seal water outlet B just.In addition, this moment is because of the end sealing of being located at a seal ring pad 4 and pressing plate 3 junctions of relief hole 7, so relief hole 7 also is in closed state.
After water level is lower than control water level in the water tank, ball float 13 descends, driving guide rod 6 makes rubber sleeve 5 leave osculum 10, osculum 10 is opened, simultaneously because the area of the cross section of water inlet 8 less than the area of osculum cross section, the described current via through holes of going up in the valve chamber D 9 is released through osculum 10, hydraulic pressure reduces in the last valve chamber D, under differential pressure action, to move on seal ring pad 4 and the pressing plate 3, water outlet B is opened.In addition, space can occur between pressing plate 3 and the seal ring pad 4 this moment, make relief hole 7 also be in open mode, the water of last valve chamber D has part to flow out through relief hole 7, the hydraulic pressure of last valve chamber D reduces rapidly, the seal ring pad 4 water outlet B water valve that speeds away is in full-gear very soon, and water inlet A and water outlet B are in connected state.
With the rising of water level in the water tank, when near control water level, ball float 13 drives guide rod 6 makes rubber sleeve 5 near osculum 10, and its streamflow is reduced.Osculum 10 place's hydraulic pressure increase.The water that is flowed out by water inlet 8 can increase gradually through water amount, hydraulic pressure increases, promote seal ring pad 4 and pressing plate 3 near water outlet B, gap smaller between seal ring pad 4 and the pressing plate 3, make relief hole 7 gradually stifled up to whole obstructions, finally sealed circle pad 4 is sealed water outlet B, and this moment, rubber sleeve 5 was sealed osculum 10, finished the pass closed procedure of water valve.For effectively helping ball float 13 returns, be provided with Returnning spring between an end of the connection rubber sleeve 5 of described guide rod 6 and the valve body.
The utility model structural device is reasonable, can change the unlatching of seal ring pad or closed condition by the pressure that changes water tank and realize being communicated with or closing between water intake and the water outlet, do not exist the mechanical ball float of existing machinery float switch to get rusty and wear and tear, flexible movements, reliable performance, long service life.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
