Abstract
Provided is a liquid magnetism annunciator. When liquid flows through a pipeline, force generated by liquid flow enables a signal lever to operate. A magnetic ring is installed on the top of the signal lever such that the signal lever drives the magnetic ring to get close to a corresponding magnetic proximity switch installed outside a body when operating. Thus, magnetic force may penetrate the body to be transmitted to the magnetic proximity switch outside the body. Therefore, the magnetic proximity switch gives an electric signal in order to achieve a purpose of controlling a device. The liquid magnetism annunciator is provided with simple structure. A sensor switch is installed outside the body and is completely separated from liquid inside the pipeline so as to prevent critical components from being corroded by the liquid in the pipeline. The liquid magnetism annunciator is easy to repair and maintain and saves cost.
Description
Technical field
The present invention relates to a kind of annunciator, especially a kind of fluid magnetic annunciator.
Background technology
Annunciator is requisite device in industrial production especially in daily life, wherein water flow switch adds the processes such as thermal control, pump switch control, the control of electromagnetically operated valve break-make or water outlet power-off, water outlet energising control for water circulation control, Inlet and outlet water control, the water of electric heater, solar water heater, air conditioner and other water systems, current is converted to the signal device of the switching regulator signal of telecommunication after reaching certain flow.Its operation principle is that the discharge in pipeline is while being greater than the flow of setting, magnetic core produces displacement and drives magnetic source to produce magnetic control effect and makes transducer output " 1 " switching signal under flow action, this signal is input to apparatus control system, realizes the object of controlling with discharge after power expands amplification.Discharge in pipeline is less than after the flow of setting, and magnetic core drives magnetic source return under back-moving spring thrust, makes transducer output " 0 " switching signal, the work of halt system.Utilize in addition in addition gravity, pressure reduction etc. to realize the water flow switch of flow detection, but the sensing element of these water flow switches all directly contacts with liquid, complex structure, switch poor durability, and the water flow switch using under various particular surroundingss is completely different, price is expensive again, make the durable degree of water flow switch too low, easily damage, and due to complex structure, after infringement, cannot repair, cause the problems such as waste of material, and in corrosive liquids (as acid, alkali, wet goods), being limited to the reasons such as material, greatly shorten the useful life of water flow switch especially.
Summary of the invention
For water flow switch, can not in different types of environment, use, and the main sensing element of switch contacts the rear shortcoming that easily burn into damages with liquid.The present invention, by simplified design, changes original signal of telecommunication send mode, can make liquid not remove to contact signal of telecommunication transmitting apparatus, and all parts are all detachable, easy to maintenance, and the whole anticorrosive that uses, and increases the service life.
The present invention solves the technical scheme that its technical side's problem adopts: whole fluid magnetic annunciator comprises: magnetic approach switch seat, body, magnet ring, signal lever, holding screw, magnetic approach switch, top screw, O RunddichtringO, hole axle; Holding screw is fixed on magnetic approach switch on the magnetic approach switch seat that is positioned at body exterior, top screw is by corresponding being arranged on body of O RunddichtringO, in body, between two top screws, be hole axle, the fulcrum location of signal lever is enclosed within on the axle of hole, the top of signal lever connects magnet ring, and the position of magnet ring is corresponding with the position of magnetic approach switch.Fluid magnetic annunciator whole installation is at pipeline external, and the vertical flow direction of the lever end of signal lever is arranged in pipeline, wherein the preferred 60 ° of angles of the top angle of top screw.
Fluid magnetic annunciator is work like this: the vertical flow direction of signal lever end of fluid magnetic annunciator is arranged in pipeline, in pipeline, liquid flows through, the strength that liquid flow produces can make signal lever action, because the top of signal lever is provided with magnet ring, during signal lever action, can drive magnet ring to approach the magnetic approach switch that correspondence is arranged on body exterior, magnetic force just can penetrate on the magnetic approach switch that body is delivered to body exterior, make magnetic approach switch send the signal of telecommunication, reach the object of control appliance.
The invention has the beneficial effects as follows, fluid magnetic annunciator is simple in structure, cheap, it is completely separated with the liquid in pipeline that annunciator switch is arranged on body exterior, avoided critical component by liquid corrosion in pipeline, and easy-maintaining maintenance, cost saved simultaneously.
Accompanying drawing explanation
Fig. 1 is vertical view cutaway drawing of the present invention.
Fig. 2 is end view of the present invention.
1. magnetic approach switch seats in figure, 2. body, 3. magnet ring, 4. signal lever, 5. holding screw, 6. magnetic approach switch, 7. top screw, 8.O RunddichtringO, 9. hole axle.
Embodiment
In Fig. 1-2, holding screw 5 is fixed on magnetic approach switch 6 on the magnetic approach switch seat 1 that is positioned at body 2 outsides, top screw 7 is by corresponding being arranged on body 2 of O RunddichtringO 8, between interior two the top screws 7 of body 2, it is hole axle 9, the fulcrum location of signal lever 4 is enclosed within on hole axle 9, the top of signal lever 4 connects magnet ring 3, and the position of magnet ring 3 is corresponding with the position of magnetic approach switch 6.Fluid magnetic annunciator whole installation is at pipeline external, and the vertical flow direction of the lever end of signal lever 4 is arranged in pipeline, wherein the preferred 60 ° of angles of the top angle of top screw 7.
The vertical flow direction of signal lever end of fluid magnetic annunciator is arranged in pipeline, in pipeline, liquid flows through, the strength that liquid flow produces can make signal lever 4 actions, because the top of signal lever 4 is provided with magnet ring 3, during signal lever 4 action, can drive magnet ring 3 to approach the magnetic approach switch 6 that correspondence is arranged on body exterior, magnetic force just can penetrate on the magnetic approach switch 6 that body 2 is delivered to body 2 outsides, makes magnetic approach switch 6 send the signal of telecommunication, reaches the object of control appliance.
The present invention is not limited to the present embodiment, and equivalent concepts or change in any technical scope disclosing in the present invention, all classify protection scope of the present invention as.
