Description
Technical field
The utility model relates to a kind of bistable state pilot valve switch gear, belongs to the pilot valve shut-off means technical field of band closure member in the mechanical engineering.
Background technique
Having the guide electromagnetic valve of controlling big flow with small-power now, all is to adopt long-term energising of electromagnetic coil or outage to control the pilot valve switch gear to move, and controls the action of main valve with this.Its working principle is: during the electromagnetic coil dead electricity, and the moving iron core of pilot valve switch gear and static iron core not adhesive under the spring force effect, main valve is under a kind of state.Electromagnetic coil gets when electric, produces certain electromagnetic force, and it will move iron core and static iron core adhesive after overcoming the deadweight or other relevant active force of spring force, moving iron core, control main valve with this and finish an action, make main valve be in another kind of state.As shown in Figure 1, this class valve has only a stable status when no electric circuit, if will be in another steady state for a long time, certainly will will give coil electricity for a long time.Particularly for the valve of the big flow of control, the power of electromagnetic coil also certainly will be bigger, and this has just increased energy consumption greatly, and because coil is switched on for a long time, the coil fault rate increases.Simultaneously, because the coil overwhelming majority that present pilot valve switch gear is adopted is used ac power supplys, the electromagnetic noise phenomenon is comparatively general, is difficult to overcome fully, has increased the disqualification rate in the manufacture process greatly.
Summary of the invention
The purpose of this utility model provides a kind of under the situation of power consumption hardly, and control is stably moved iron core and static iron core adhesive or disconnected the bistable state pilot valve switch gear of two kinds of steady states.
The utility model is a bistable state pilot valve switch gear, is provided with the moving iron core of spring in comprising, places the static iron core on moving iron core top, it is characterized in that the top of described static iron core or bottom also are provided with permanent magnet simultaneously.During work, by being attached to the outer direct current lopping of static iron core and the effect of pulse power supply signal.The magnetic field that the magnetic field of permanent magnet and coil are produced is equidirectional or in the other direction, thereby the total magnetic field is strengthened or weakens, and acts on the moving iron core, makes static iron core and moving iron core be in stable adhesive or off state.
When permanent magnet places the bottom of static iron core, between described permanent magnet and moving iron core, also auxiliary static iron core can be set.Described static iron core middle part also can be provided with seal ring.
Described static iron core or auxiliary static iron core bottom also can offer slotted eye, to strengthen the peripheral magnetic field of static iron core or auxiliary static iron core.
Described static iron core, auxiliary static iron core, moving iron core also can be provided with not magnetic conduction sleeve pipe outward simultaneously.
The utility model on the basis of existing pilot valve switch gear structure, on static iron core top or the bottom permanent magnet is set, and adopt dc coil and pulse power supply signal to act on the permanent magnet, move.Because pulse power supply only provides pulse signal forward or backwards, be Millisecond current"on"time, can reach energy-conservation purpose more easily.The steady state of this device mainly relies on the stationary magnetic field of permanent magnet to guarantee in addition, does not have noise problem.Compared with prior art, technology is more or less the same, and almost can not increase manufacture cost, but energy-saving effect is obvious, and can effectively reduce the rate of fault of coil and eliminate fault such as electromagnetic noise.Simultaneously, the utility model also can need can be divided into built-in and two kinds of structural types of external according to manufacturing process, when static iron core and sleeve pipe employing welding manner, must adopt external, and the then inside and outside formula of putting of all the other modes all can.Automatic control and state that the utility model can be widely used in various liquid mediums switch, and be widely applicable.

Among the figure: 1 is the electromagnetic valve body assembly, and 2 are moving iron core, and 3 be spring, and 4 are magnetic conduction sleeve pipe not, and 5 is short-circuited conducting sleeve, and 6 is static iron core, and 7 is permanent magnet, and 8 is slotted eye, and 9 is coil, and 10 is to assist static iron core, and 11 is seal ring.
Embodiment
The utility model is mainly by the not magnetic conduction sleeve pipe 4 that places on the electromagnetic valve body assembly 1, places moving iron core 2 and static iron core 6 in the magnetic conduction sleeve pipe 4 not, places the spring 3 in the moving iron core 2, places the formations such as permanent magnet 7 of static iron core 6 tops or bottom.
Fig. 2,3 is the structural type of external bistable state pilot valve switch gear, static iron core 6 adopts welding manners with magnetic conduction sleeve pipe 4 not, permanent magnet 7 usefulness glue are bonded in the top of static iron core 6, be positioned at not outside the magnetic conduction sleeve pipe 4, can eliminate the influence of welding high temperature to permanent magnet 7 magnetic intensities, the bottom of static iron core 6 offers slotted eye 8.
Fig. 4,5 is the structural type of built-in bistable state pilot valve switch gear, permanent magnet 7 is installed on the bottom of static iron core 6, and an auxiliary static iron core 10 is set in the bottom of permanent magnet 7 again, static iron core 6 adopts the roll extrusion modes to connect with magnetic conduction sleeve pipe not 4, rely on O-ring seals 11 to seal, the bottom of auxiliary static iron core 10 also offers slotted eye 8.
During use, it is outer and use bolt that dc coil 9 is enclosed within not magnetic conduction sleeve pipe 4.When coil 9 feeds direct impulse voltage, the electromagnetic force sum of the electromagnetic attraction that coil 9 produces and permanent magnet 7 generations is greater than elastic force and other relevant active force of spring 3, make iron core 2 and static iron core 6 (or auxiliary static iron core 10) adhesive, at this moment, because the magnetic loop magnetic resistance of permanent magnet 7 reduces greatly, the magnetic force that permanent magnet 7 is produced is enough to overcome the elastic force of spring 3 and is in stable attracting state (as Fig. 3, shown in Figure 5), in case pulse signal disappears, can not change the attracting state of moving iron core 2 yet.
When coil 9 feeds reverse pulse signal, because the magnetic field that magnetic field that coil 9 produces and permanent magnet 7 produce is in the other direction, both stacks, the total magnetic field is very weak, magnetic force is much smaller than the elastic force of spring 3, iron core 2 and static iron core 6 (or auxiliary static iron core 10) are disconnected, thereby be in stable off state (as Fig. 2, shown in Figure 4).So, the continuous conversion of the positive and negative both direction of pulse signal, moving iron core 2 and static iron core 6 (or auxiliary static iron core 10) corresponding change in adhesive and two steady states of disconnection are finished the various work of main valve with this.
