Abstract
The utility model discloses a water flow indicator, which includes a cover, a seat, a micro-switch, a sensor component, a positioning sheet and a blade, wherein the cover is fixed connection with the seat. The water flow indicator is characterized in the sensor component comprises a diaphragm fixed between the cover and the seat, and a sensing rod passing through the diaphragm; the lower end of the sensing rod is connected to the blade through a swinging piece, while the upper end of the sensing rod is connected to a regulation wheel having an outer round oblique surface in contact with the tip of the micro-switch; the micro-switch is equipped with an output terminal in connection with the alarm controller circuit; the upper end of the sensing rod is also provided with a pulling spring which is in connection with the regulating screw bolt, and the positioning sheet is positioned on one side of the swinging piece and in fixed connection with the seat. The utility model is simple in structure, convenient for regulation, high in sensitivity, and great in stability.
Description
[technical field]
The utility model relates to the additional alarm device in the automatic sprinkler system, is specifically related to a kind of improvement invention of water flow indicator.
[background technology]
Water flow indicator is the additional alarm device in the automatic sprinkler system, generally is installed on each subregion distributing main of system or the sparge pipe, and the conversion of signals that water can be flowed is the signal of telecommunication, to the effect of system implementation monitoring, warning.The general structure more complicated of existing water flow indicator, adjusting is inconvenient, sensitivity is relatively poor, stability is bad.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is the water flow indicator that is to provide a kind of simple in structure, easy to adjust, highly sensitive, good stability.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of water flow indicator, comprise case, base, sensitive switch, sensory package, spacer and blade, case is fixedlyed connected with base, it is characterized in that: described sensory package comprises sensor bar and diaphragm, diaphragm is fixed between case and the base, sensor bar passes in the middle of the diaphragm, the sensor bar lower end connects described blade by the swing sheet, the sensor bar upper end is connected with regulating wheel, the cylindrical inclined-plane of regulating wheel contacts with the contact of described sensitive switch, and sensitive switch is provided with the lead-out terminal that is connected with the alarm controller circuit, and described sensor bar upper end also is provided with extension spring, extension spring is connected with adjustment screw, and described spacer is located at swing sheet side and fixedlys connected with base.
The utility model is simple in structure, and its sensor bar upper end is connected with regulating wheel, and regulating wheel can conveniently be regulated on sensor bar, makes the contact pressure between regulating wheel and the sensitive switch be adjusted to the best, makes water flow indicator keep good sensitivity; Be connected with the extension spring that to regulate pulling force on the sensor bar, like this when water flow indicator is used in different operational environments, can make things convenient for as required and regulate set suitable pretightning force, be unlikely to the variation of water flow pressure and send wrong Pressure Alarm, good stability.
