Description
Technical field
The utility model relates to control valve field, is specially a kind of Novel flow rate switch.
Background technique
Flow switch is mainly online in water, gas, wet goods medium pipeline or plug-in type is installed the size of monitoring water flow in water system.Trigger output alarm signal in water flow higher or lower than some set points time and pass to unit, after system acquisition signal, can make corresponding instruction action.
At present, flow switch is mainly used in cooling, the lubrication system of nuclear power fire-fighting system, main equipment, realizes the control, supervision, safety interlocking of fluid flow etc., to ensure the safe operation of equipment, and steady production flow process, the automatic controlling level that improves.Current a kind of Novel flow rate switch both domestic and external mainly contains float-type and Flapper type.When fluid enters after housing, along with the increase of flow, float rises, baffle plate turning, drives magnet steel fixing on float and baffle plate to rise, in the time being raised to certain position, close with two outer steel misfortunes of external alert part, magnet steel frame is swung, press sensitive switch switching and send contact point signal.Because movable piece is too much, make alarm point poor repeatability, the structures shape of sensor the flow alarm point of sensor can not be too little, can only reach more than 6% could reporting to the police of flow CLV ceiling limit value.
Notification number is that the Chinese patent of CN203456380U discloses a kind of flow switch, is specifically related to a kind of Novel flow rate switch that a kind of tiny flow quantity control is reported to the police.The technical problem solving is that current a kind of Novel flow rate switch movable piece is too much, alarm point poor repeatability.The utility model comprises housing and is positioned at the hinge turnover panel of housing, on described hinge turnover panel, be provided with magnet steel, at the outer installment magnetic switch of housing, when magnet steel deflects with hinge turnover panel, the contact action of magnetic switch, but its sensitivity is low, be easy to break down, maintenance maintenance cost is high.
Model utility content
