Description
Technical field
The utility model relates to control valve field, is specially a kind of flow 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.In water flow, trigger output alarm signal higher or lower than some set points time and pass to unit, after system acquisition signal, can make corresponding indication 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 guarantee the safe operation of equipment, and steady production flow process, the automatic controlling level that improves.Current flow 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, when 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 tiny flow quantity and controls the flow switch of reporting to the police.The technical problem solving is that current flow switch movable piece is too much, alarm point poor repeatability.The hinge turnover panel that the utility model comprises housing and is positioned at housing, on described hinge turnover panel, be provided with magnet steel, outer installment magnetic switch at 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
The technical problem that the utility model solves is to provide a kind of flow switch, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: flow switch, comprise: erection joint, flow to pole socket, adjustment seat, flow drive link, described adjustment seat inside is provided with cavity volume, in cavity volume, be provided with and flow to pole socket, flow to pole socket one end and be arranged on adjustment seat inside, the other end stretches out adjustment seat, adjustment seat inner with flow to the vertical flow switch that arranges of pole socket, flow switch is arranged on adjustment seat inside by retaining screw, in adjustment seat, be provided with Flow-rate adjustment hole with flow switch horizontal position, adjustment seat one side is provided with perforate, in perforate, be provided with adjusting screw, adjusting screw outer end is provided with back-up ring, back-up ring and adjusting screw joint are provided with pad, both sides, adjusting screw outer end are provided with spring, flow to pole socket inside and be provided with flow drive link, flow drive link one end is connected in flow switch, the other end extends in valve, flow to pole socket lower end and be provided with erection joint, erection joint is connected by attaching nut with flowing between pole socket.
Inside, described Flow-rate adjustment hole is provided with yardstick screw thread.
Described erection joint and flow to joint between pole socket and be provided with seal ring.
Described flow direction between pole socket and flow drive link is provided with taper stop block.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, stable performance, highly sensitive, easy for installation, be convenient to maintenance and repair, reproducible.
