Abstract
Middle water guide type pulse water switch, belongs to magnetic induction technical field.It is to have added an ater guide piece in the middle part of the water inlet of middle water guide type pulse water switch housing, water pipe intermediate flow stablized quick flowing water all centralized collection, it is punched on the impeller of middle water guide type pulse water switch, impeller is made stably to rotate, thus band moving magnet rotates, and have the positive negative pole sensing Hall element of Magnet, so that metering and switch reach relatively reliable stable purpose, as long as there being water to flow, pressure hour also can work, and does not reduce water flowing area and does not also interfere with discharge.
Description
Technical field
The present invention relates to magnetic induction technical field, be specifically related to a kind of middle water guide type pulse water switch technical field.
Background technology
Current pulse water flow switch, is essentially all by the flowing water of pipeline, freely in impact flow water flow switch
Impeller rotates, and band moving magnet rotates, Magnet sensing Hall element reach the purpose of work, exist according to hydromechanical principle
The water of flowing in water pipe, middle part is that flow velocity is the fastest all the time, maximum flow, it is simply that at pressure hour, do not reach the feelings of turbulent flow
During condition, in pipe, four wall water are static, and the water of centre is still in flowing, so in order to allow water fully make impeller rotate, will make
Impeller strengthens and the volume of water flow switch also will be made to strengthen simultaneously, and on the other hand hydraulic pressure also can make impeller rotate shakiness when less
Or do not rotate, not only having influence on using effect, the parameter that also can be used in 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, has added an ater guide piece, such nothing
Opinion discharge is much, all the water of water pipe intermediate flow can be concentrated and is punched on the impeller of middle water guide type pulse water switch, reaches
Purpose to stable switch gage work.
The present invention solves technical problem and be the technical scheme is that entering at middle water guide type pulse water switch housing
The middle part at the mouth of a river, becomes a fixed inclination 30 degree to add ater guide piece to 60 degree, is all concentrated by quick for water pipe intermediate stable flowing water
After collection, it is punched on the impeller of middle water guide type pulse water switch, makes impeller stably rotate, thus band moving magnet rotates, and
Having the positive negative pole sensing Hall element of Magnet, reach the purpose of metering and switch, Hall element is fixed on middle water guide
On the housing of formula pulse water flow switch, with the Magnet in rotating shaft on a horizontal plane, impeller and Magnet are all installed in rotating shaft,
In the impeller cavity of the one side that rotating shaft is contained in middle water guide type pulse water switch housing, can rotate freely, impeller cavity and current
Direction is vertical, the current area reduced because of ater guide piece, has impeller cavity to supplement, the most also would not reduce water flowing area, also
Do not interfere with discharge.
The invention has the beneficial effects as follows: make the middle flowing water in middle water guide type pulse water switch, can concentrate stable
After collection, it is punched on the impeller of middle water guide type pulse water switch, and makes impeller stably rotate, so that metering and switch work
Reaching relatively reliable stable purpose, as long as there being water to flow, pressure hour also can work, and can't affect discharge.
Accompanying drawing explanation
With embodiment, present configuration is further illustrated below in conjunction with the accompanying drawings.
In figure: 1. enter head piece, 2. housing, 3. ater guide piece, 4. impeller, 5. impeller cavity, 6. Magnet, 7. rotating shaft, 8. Hall unit
Part.
Detailed description of the invention
In the drawings, 60 degree of oblique angles are pressed in the middle part of the water inlet (1) in middle water guide type pulse water switch housing (2)
Add an ater guide piece (3), water pipe intermediate flow stablized quick flowing water all centralized collection, be punched in middle water guide formula pulsating water
On the impeller (4) of stream switch, make the stable rotation of impeller (4), thus band moving magnet (6) rotates, and have the positive negative pole of Magnet (6)
Sensing Hall element (8), reaches the purpose of metering and switch, and Hall element (8) is fixed on middle water guide type pulse water
On the housing (2) of switch, with the Magnet (6) in rotating shaft (7) on a horizontal plane, impeller (4) and Magnet (6) are all installed in turning
On axle (7), rotating shaft (7) is contained in the impeller cavity (5) of the one side of middle water guide type pulse water switch housing (2), can be freely
Rotating, impeller cavity (5) is vertical with water (flow) direction, and the current area simultaneously reduced because of ater guide piece (3) has again impeller cavity (5) to carry out
Supplement, because without reducing water flowing area, not interfering with discharge.
Claims (1)
1. middle water guide type pulse water switch, is the pulsed water flow switch of Magnet sensing Hall element, and its basic feature is:
In the middle part of the water inlet of middle water guide type pulse water switch housing, becoming a fixed inclination, added ater guide piece, angle exists
Between 30-60 °, ater guide piece surrounding can also normally water flowing, the water of middle part is collected and is punched on impeller, Hall element is fixed on
On the housing of middle water guide type pulse water switch, with the Magnet in rotating shaft on a horizontal plane, impeller and Magnet are all dresses
In rotating shaft, in the impeller cavity of the one side that rotating shaft is contained in middle water guide type pulse water switch housing, by water impulsion impeller rotation
Turning, impeller cavity is vertical with water (flow) direction.
