Abstract
The invention discloses a middle water guide type pulse water switch and belongs to the technical field of magnetic induction. A water guide piece is added in the middle of a water inlet of a shell of the middle water guide type pulse water switch, and stable and fast flowing water flowing in the middle of a water pipe is collected concentratedly to flush on an impeller of the middle water guide type pulse water switch, so that the impeller rotates so as to drive a magnet to rotate. Besides, positive and negative magnetic poles of the magnet induce a Hall element, so that metering and switch operation are more reliable and stable, operation is also performed as long as water flows when pressure is low, and a water supply area is not decreased while water flow is unaffected.
Description
Technical field
The present invention relates to the magnetic induction technical field, be specifically related to a kind of middle water guide formula pulse water flow switching technique field.
Background technology
Present pulse water flow switch, basically all be the flowing water by pipeline, the vane rotary in the impact flow water flow switch freely, the rotation of band moving magnet, reached the purpose of work by magnet induction Hall element, the water that in water pipe, flows according to hydromechanical principle, the middle part is that flow velocity is the fastest all the time, flow is maximum, be exactly at pressure hour, when not reaching the situation of turbulent flow, Guan in wall water be static, and middle water is still flowing, so in order to allow water fully make vane rotary, the volume that impeller is strengthened also will make water flow switch simultaneously strengthens, hydraulic pressure hour also can make vane rotary unstable or do not rotate on the other hand, not only have influence on result of use, the parameter that also can be used in the water metering is unstable.
Summary of the invention
The present invention is exactly the middle part in the water inlet of pulsed water flow switch, added an ater guide piece, so no matter discharge is much, all can be the water of water pipe intermediate flow, concentrate on the impeller of water guide formula pulse water flow switch in the middle of being punched in, reach the purpose of stable switch gage work.
The technical scheme that technical solution problem of the present invention adopts is: in the middle part of the water inlet of middle water guide formula pulse water flow switch case, become a fixed inclination 30 degree to add ater guide piece to 60 degree, with water pipe intermediate stable flowing water all after the centralized collection fast, be punched on the impeller of middle water guide formula pulse water flow switch, make the stable rotation of impeller, thereby band moving magnet rotation, and there is the positive negative pole of magnet to respond to Hall element, reach the purpose of metering and switch, Hall element is fixed on the housing of middle water guide formula pulse water flow switch, with magnet in the rotating shaft on a horizontal plane, impeller and magnet all are to be contained in the rotating shaft, in the impeller cavity of a side of water guide formula pulse water flow switch case, can rotate freely in the middle of rotating shaft is contained in, impeller cavity is vertical with water (flow) direction, the current area that reduces because of ater guide piece, there is impeller cavity to replenish, so also just can not reduce the water flowing area, also can not affect discharge.
The invention has the beneficial effects as follows: the middle flowing water in the middle of making in the water guide formula pulse water flow switch, after concentrating stable collection, be punched on the impeller of middle water guide formula pulse water flow switch, and make impeller stablize rotation, thereby make metering and switch reach more reliable and stable purpose, as long as water flow is arranged, pressure hour also can be worked, and can't affect discharge.
Description of drawings
Below in conjunction with drawings and Examples structure of the present invention is further specified.
Among the figure: 1. enter head piece, 2. housing, 3. ater guide piece, 4. impeller, 5. impeller cavity, 6. magnet, 7. rotating shaft, 8. Hall element.
Embodiment
In the drawings, middle part at the water inlet (1) of middle water guide formula pulse water flow switch case (2) has added an ater guide piece (3) by 60 degree oblique angles, with the quick flowing water of stablizing of water pipe intermediate flow centralized collection all, be punched on the impeller (4) of middle water guide formula pulse water flow switch, make the stable rotation of impeller (4), thereby band moving magnet (6) rotation, and there is the positive negative pole of magnet (6) to respond to Hall element (8), reach the purpose of metering and switch, Hall element (8) is fixed on the housing (2) of middle water guide formula pulse water flow switch, with magnet (6) in the rotating shaft (7) on a horizontal plane, impeller (4) and magnet (6) all are to be contained in the rotating shaft (7), in the middle of rotating shaft (7) is contained in the impeller cavity (5) of a side of water guide formula pulse water flow switch case (2), can rotate freely, impeller cavity (5) is vertical with water (flow) direction, the current area that reduces because of ater guide piece (3) simultaneously has again impeller cavity (5) to replenish, thereby can not reduce the water flowing area, can not affect discharge.
Claims (3)
1. middle water guide formula pulse water flow switch, it is the pulsed water flow switch of magnet induction Hall element, its essential characteristic is: in the middle part of the water inlet of middle water guide formula pulse water flow switch case, become a fixed inclination to add ater guide piece, the water collection of middle part is punched on the impeller, Hall element is fixed on the housing of middle water guide formula pulse water flow switch, with magnet in the rotating shaft on a horizontal plane, impeller and magnet all are to be contained in the rotating shaft, in the middle of rotating shaft is contained in the impeller cavity of a side of water guide formula pulse water flow switch case, by water impulsion vane rotary, impeller cavity is vertical with water (flow) direction.
2. water guide formula pulse water flow switch in the middle of according to claim 1, its essential characteristic is: ask that the position becomes a fixed inclination to add an ater guide piece in the water inlet of middle water guide formula pulse water flow switch case.
3. water guide formula pulse water flow switch in the middle of according to claim 1, its essential characteristic is: become the angle of a fixed inclination should be at 30 degree between 60 degree.
