Description

Current limliting voltage stabilizing multifunctional electromagnetic valves

The utility model is about a kind of solenoid valve that has the current limliting structure of voltage regulation.

Its spool of existing traditional electrical magnet valve is under spring and the double effect of electromagnetic coil, energising by the electromagnetic coil whether spool in the control electromagnetic valve is moved and is opened or block liquid stream respectively, and the occasion of regulating loine pressure and flow at needs, for example in reverse osmosis water treatment system; It is not enough that solenoid valve is only arranged, regulate loine pressure and flow purpose in order to reach, also need there be throttle valve to be connected in parallel in the pipeline, conventional throttle valve structure mainly contains cone structure or capillary pipe structure form, above-mentioned two structures form throttle valve when small flow is worked, its instability of flow often, so far, need big flow liquid stream at the same time and pipeline is carried out pressure and Flow-rate adjustment occasion, still lack a control valve special of controlling stable and complete function.

The purpose of the utility model is throttle valve structure and electromagnetic valve structure will be combined and improved to overcome problems such as working stability itself that exist and function singleness between the two.

Current limliting voltage stabilizing multifunctional electromagnetic valves described in the utility model still has magnetic guiding loop, separation sleeve, electromagnetic valve core and spring thereof, electromagnetic coil, coil stationary frame, flow to out at valve body liquid and to be provided with the interlock of valve plug and electromagnetic valve core between the shape chamber, it is characterized in that valve body liquid flows to out the taper current limliting spool that is provided with pod apertures in addition between the shape chamber and is mated, this current limliting spool tail end is provided with stage clip, and its current limliting adjusting screw spring seat and seal ring thereof place valve body that the shape hole is installed.

Current limliting voltage stabilizing multifunctional electromagnetic valves with said structure characteristics is combined solenoid valve and throttle functionality dexterously, and can accomplish that small flow is stable, liquid stream such as does not block at advantage, in addition, the utility model is applied to liquid fluid system, and to play a valve dual-purpose, and system pressure is stable before guaranteeing again.

Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.

Fig. 1 is the utility model example structure sectional view.

Fig. 2 is Figure 1A-A sectional view.

Wherein: 1, magnetic guiding loop; 2, separation sleeve; 3, spring; 4, coil; 5, electromagnetic valve core; 6, coil stationary frame; 7, valve plug; 8, underpressure chamber; 9, valve plug; 10, seal ring; 11, current limliting adjusting screw spring seat; 13, current limliting spool; 14, valve body; 15, coil inserted sheet.

As shown in the figure, the utility model improvements are to flow to out the taper current limliting spool 13 that is provided with pod apertures in addition between the shape chamber and is mated at valve body 14 liquid, current limliting spool 13 tail ends are provided with stage clip 12, its current limliting adjusting screw spring seat 11 and 10 of seal rings thereof place valve body 14 mounting holes, the pressure of system before just the flow of energy regulator solution stream reaches by adjusting screw spring seat 11 positions, can guarantee that the preceding system pressure of liquid stream is stable owing to establish stage clip 12 behind the taper current limliting spool 13, and can accomplish that small flow is stable, and the electromagnetic valve structure of present embodiment is still by magnetic guiding loop 1, separation sleeve 2, electromagnetic valve core 5 and spring 3 thereof, coil 4, coil stationary frame 6, valve plug 7 compositions such as grade, valve plug 7 is fixed on the electromagnetic valve core 5, and valve body 14 liquid flow to out between another valve plug 9 that is provided with between the shape chamber has underpressure chamber 8 structures, this underpressure chamber 8 has inlet opening and liquid outlet opening, its liquid outlet opening flows out degree of lip-rounding chamber UNICOM over against valve plug 7 and with valve body 14 liquid, during the solenoid valve no electric circuit, valve plug 7 is pressed on 8 liquid outlet openings of underpressure chamber, with valve plug 9 valve body 14 liquid being flow to out the shape chamber intercepts, the pod apertures that liquid stream only is provided with by other, under 13 effects of taper current limliting spool, whole system is in the flow restriction state, for example be applied in the reverse osmosis water treatment system, this valve can play a machine two valve actions, be to have played throttling action during electromagnetic valve coil 4 no electric circuits as previously mentioned, and the performances such as small flow instability that in the past existed with throttle valve have separately been improved, when having arrived reverse osmosis membrane and having needed big flow flushing, solenoid valve is switched on, electromagnetic valve core 5 overcomes spring force and moves up under the effect of electromagnetic force, valve plug 7 is at first opened the liquid outlet opening in the underpressure chamber, and then valve plug 9 also is opened under the effect of preceding system pipeline high pressure, liquid stream by the present embodiment valve has big flow to flow through, use for system's control, in the present embodiment, the interaction energy of setting up underpressure chamber 8 makes electromagnetic valve core 5 its valve plugs 7 of driving more reliable more laborsaving, can improve system's precise control and sensitivity.
