Abstract
The utility model relates to a novel self-sustained electromagnetic valve which is provided with only one coil; a fixed iron core comprises permanent magnetic materials; a plastic sealing coil component is directly used as a valve cover; one end of a coil frame in the component is embedded with the fixed iron core; the inner hole is directly used as a movable iron core guide tube. The electromagnet valve has the advantages of simple structure, energy saving and convenient control, which is suitable for waterproof explosion-proof occasions needing lead seal (e. g. matched with a fluid meter); the utility model with wide purpose ranges can be used as a guide control valve.
Description
Solenoid valve is widely used a kind of robot control system(RCS) final controlling element, the valve of a kind of automatic control of more specifically saying so.
The Kai Heguan of common solenoid valve is decided by the logical and disconnected of electric current in the coil.And self-sustaining type solenoid valve is only given the electrical signal that triggers, and makes the switch state of valve.It is divided into patterns such as machinery maintenance, magnetic maintenance.And the magnetism holding type solenoid valve usually must two coils be controlled it respectively and is opened and close.The instantaneous energising of coil, moving iron core is attracted to static iron core, and the outage back keeps the adhesive of iron core by the magnetic of permanent magnet.Another coil electricity, moving iron core breaks away from static iron core, makes two iron cores keep separating by spring force.Such valve mechanism complexity, and the clutch state of two iron cores is difficult to differentiate outside valve.
The objective of the invention is to: one provides a kind of magnetism holding type solenoid valve that need only a coil; Its two, make this electromagnetic valve structure that has only a coil simple as far as possible, with low cost and action is reliable; Its three, make this solenoid valve can be applicable to waterproof anti-explosion safely and need the occasion of lead sealing.
The present invention achieves the above object by following technological scheme:
(1) solenoid valve is only used a coil, and its static iron core is made by permanent-magnet material or be synthetic in the soft magnetic bodies outside by permanent magnet.
(2) utilize its endoporus directly to serve as the conduit of moving iron core as the coil carrier in its coil component of (1) described solenoid valve; Further design directly is embedded in static iron core in the coil carrier.
(3) as (1) or (2) described solenoid valve, again coil is encapsulated with plastics together with concentrating flux plate, and, also had the aperture of using for plumbous dress threading on the coil component directly as valve gap.
The present invention compared with prior art has following tangible advantage:
(1) simple in structure, (2) manufacturing process is simple.(3) two iron core clutch states depend on the polarity of coil energising last time, are convenient to control.(4) coil after the encapsulation also is applicable to the metering occasion of waterproof, explosion-proof and necessary lead sealing.
Below we contrast accompanying drawing in conjunction with the embodiments, the invention will be further described.
Fig. 1 is the structural representation of example I.
Solenoid valve is made up of valve body 1, coil component 2, moving iron core 3, Returnning spring 4, seal ring 5.Coil carrier 21 is arranged in the coil component 2, slide in the endoporus of moving iron core 3 direct-on-line circle framves 21.Static iron core 22 make by permanent-magnet material or by permanent magnet 23 multiple in soft magnetic bodies 2 outsides as inserts, when coil is put up type, just be fixed on an end of coil carrier endoporus.Coil carrier 21 is around with coil 24, together with the outer concentrating flux plate 25 of coil carrier, is integral with plastic capsulation, is called coil component 2.The usefulness of aperture 26 for plumbous dress threading is arranged on the coil component.Coil component 2 is directly as valve gap.Example I shown in Figure 1 is the situation of little latus rectum, directly utilizes the screw thread on the coil carrier to be connected with valve body.
I embodiment illustrated in fig. 2 is applicable to the situation that latus rectum is bigger.With 25 the load spares of the concentrating flux plate in the coil component 2 as valve gap, on through hole is arranged, be connected with valve body with screw 6.
Above-mentioned two embodiments' magnetism holding type solenoid valve adopts DC electrical source.When feeding forward current, moving iron core is by the static iron core adhesive, and coil promptly cuts off the power supply after the adhesive, and the outage back makes iron core keep adhesive by the magnetic force of permanent magnetism.When feeding back current, the magnetic force of generation is opposite with the magnetic force direction of permanent-magnet pieces, and moving iron core resets under the effect of spring force again, and two iron cores are in separated state.The outage back is owing to two iron core apart from each others, and permanent magnetism power is less than spring force, and iron core keeps separating.Iron core adhesive face is the plane or the conical surface, determines during specific design.
Magnetism holding type solenoid valve of the present invention is owing to have simple and reliable, with low cost, energy saving, be convenient to advantage such as control and have purposes very widely.Except that being directly used in control the opening and close of fluid, also can be used as the pilot-actuated valve of big latus rectum or High Pressure Difference autocontrol valve.
