Description
Technical field
The utility model relates to sensor field, in particular to a kind of idle water flow sensing unit.
Background technique
As watering equipment is more and more intelligent, integrated, the use of the water flow sensor for water flow induction is also got over
Come more extensive but current water flow sensor have the shortcomings that it is respectively different: common Water-gas linkage hair need to increase into
Water pressure is not suitable for the lower remote districts of part hydraulic pressure or the lower old residential area of hydraulic pressure；Tongue tube low hydraulic pressure valve because
Internal design feature has that stuck, erroneous judgement probability is larger；There are price height, appearance selection for common water flow sensing unit
Less, the high disadvantage of energy consumption.And the utility model relates to sensor just compensate for existing water flow sensing unit the shortcomings that, have sentence
It cuts off the water supply and forces down, safe and punctual sentences and the characteristics of low energy consumption.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of idle water flow sensing units, and structure is simple, can be with
Induced current is generated by the flowing of water flow, and by faradic size, realizes the automatic opening of machine, close.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of idle water flow sensing unit is provided,
Including sensor main body, the sensor main body is L-shaped, and the lower end of the sensor main body is equipped with water supply connector, institute
The upside one end insertion for the sensor main body stated is equipped with valve shaft, and the sensor main body is internally located at the upper of water supply connector
End is equipped with Magnmet rotor component, position installation corresponding with Magnmet rotor component on the lateral wall of the sensor main body
There is hall sensing component.
As supplement, upside one end of the sensor main body is equipped with the pressing plate that valve shaft is fixed, the pressing plate
It is connected and fixed by screw and sensor main body.
It is connected and fixed preferably, the water supply connector passes through the U-shaped bolt being inserted radially into sensor main body.
Further, the lower end of the Magnmet rotor component is equipped with the metal card being connected with sensor main body inner wall
Ring limits Magnmet rotor component.
Further, O-shaped sealing is mounted between the water supply connector and the inner sidewall of valve shaft and sensor main body
Circle.
Further, the side of the water supply connector is connected and installed with relief valve.
The utility model has the advantages that structure is simple the utility model relates to a kind of idle water flow sensing unit, easy for installation, Ke Yitong
The flowing for crossing water flow generates induced current, realizes the conversion of water-flow signal to electric signal, and by faradic size, realizes
The automatic opening and closing of machine.
Detailed description of the invention
Fig. 1 is the three-dimensional structure diagram of the utility model；
Fig. 2 is the half-sectional structure chart of main view of the utility model；
Fig. 3 is the exploded perspective structure chart of the utility model.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figure 1-3, the embodiments of the present invention is related to a kind of idle water flow sensing unit, including sensor master
Body 4, the sensor main body 4 is L-shaped, and the lower end of the sensor main body 4 is equipped with water supply connector 12, the sensing
Upside one end insertion of device main body 4 is equipped with valve shaft 2, the upper end for being internally located at water supply connector 12 of the sensor main body 4
Magnmet rotor component 8, position peace corresponding with Magnmet rotor component 8 on the lateral wall of the sensor main body 4 are installed
Equipped with hall sensing component 5.
Hall sensing component 5 is 2 wire type Hall elements, can be passed through when the Magnmet rotor in Magnmet rotor component 8 rotates
The conversion output pulse width signal of magnetic pole.
When not having water flow, Magnmet rotor does not rotate, and Hall element no signal output, pulse igniter does not receive letter
Number, with standby mode at complete machine, not loss of electricity.
When having water flowing in pipeline, Magnmet rotor rotation, hall element output signal, when the signal lower limit value for reaching setting
When, sensitizing pulse igniter realizes the booting operation of complete machine.
When water flow is reduced to the lower limit value of setting, corresponding hall element output signal is attenuated to be set the board of operation
Fixed lower limit value, pulse igniter enter shutdown process according to pre-set programs.
Upside one end of the sensor main body 4 is equipped with the pressing plate 1 that valve shaft 2 is fixed, and the pressing plate 1 passes through spiral shell
Nail 6 is connected and fixed with sensor main body 4.
The water supply connector 12 passes through the U-shaped bolt 7 being inserted radially into and is connected and fixed with sensor main body 4.
The lower end of the Magnmet rotor component 8 is equipped with the metal clasp 9 being connected with 4 inner wall of sensor main body, to magnetic
Iron rotor assembly 8 limits.
O-ring seal 3 is mounted between the water supply connector 12 and valve shaft 2 and the inner sidewall of sensor main body 4.
The side of the water supply connector 12 is connected and installed with relief valve 10.
The utility model structure is simple, easy for installation, can generate induced current by the flowing of water flow, realize water flow letter
The conversion for number arriving electric signal realizes the automatic opening and closing of machine and by faradic size.
