Abstract
The utility model relates to a variable flow electromagnetic valve. The utility model is characterized in that the variable flow electromagnetic valve comprises a valve body 5, an electromagnetic coil 6 sheathed outside a valve body 5, a magnetic steel 8 in the cavity of the valve body 5, a small spring 7 positioned above the magnetic steel 8, and a valve positioned under the magnetic steel 8. The flow control can be realized by changing the value of the current in the electromagnetic coil. The utility model is particularly suitable for the automatic control of the gas quantity for a gas type rapid water heater, etc., and the purpose of realizing the constant water temperature can be obtained.
Description
The utility model relates to a kind of valve.
In the prior art, solenoid valve is the unlatching that comes control valve by the control field coil, at present, can only be in two kinds of working staties of standard-sized sheet and full cut-off, and for the occasion that needs are regulated flow, above-mentioned valve is just inapplicable.
The purpose of this utility model is to provide a kind of can come the solenoid valve of control valve aperture by changing the field current size.
The technical solution of the utility model is: the utility model comprises valve body, is enclosed within the electromagnetic coil of valve body outside, the permanent-magnet steel in the body cavity, be positioned at the permanent-magnet steel top little spring, be positioned at the valve of permanent-magnet steel below.The polarity of permanent-magnet steel is identical with the polarity of electromagnetic coil, and like this, after electromagnetic coil passed to direct current, electromagnetic coil can produce a repulsion that makes progress to permanent-magnet steel, and the size of repulsion is directly proportional with the size of current of electromagnetic coil.When the pressure that overcomes the little spring of compression when this repulsion promotes permanent-magnet steel and axially upwards slides, can open the valve of permanent-magnet steel below.Electric current in the electromagnetic coil is big more, permanent-magnet steel also big more to top offset, and the open degree of valve is also big more.
The utility model compared with prior art has following advantage:
The utility model can pass through the aperture of the big or small control valve of change field current, is convenient to the intellectuality control of solenoid valve especially; The different structure of the valve of permanent-magnet steel below can make solenoid valve be suitable for various occasions.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is structure master's sectional view of the present utility model; Wherein:
1. valve seat; 2. spool; 3. big valve film; 4. big spring; 5. valve body; 6. electromagnetic coil; 7. little spring; 8. magnet steel; 9. little valve film; 10. throttle orifice mouth; 11. pulling block; 12. import; 13. flow control groove; 14. outlet.
Referring to accompanying drawing, the utility model comprises valve body 5, is enclosed within the electromagnetic coil 6 of valve body 5 outsides, the magnet steel 8 in valve body 5 inner chambers, be positioned at magnet steel 8 tops little spring 7, be positioned at the valve of magnet steel 8 belows.Described electromagnetic coil 6 be two repeatedly put up and down, polarity is opposite, Number of ampere turns is identical same core coil, described magnet steel 8 is identical with the polarity of a following electromagnetic coil.The effect that 6 pairs of magnet steel 8 of electromagnetic coil above making play to draw, the effect that 6 pairs of magnet steel 8 of the electromagnetic coil of below play to push away can be stablized magnet steel like this, more helps the stability of flow control.The valve of described magnet steel 8 belows comprises a fore flow metered valve and a variable flow rate valve; Described fore flow metered valve comprises the spool 2 of the little valve film 9 that is fixed in magnet steel 8 underparts and little valve film below, the inner chamber of described spool 2 with export 14 and communicate; Described variable flow rate valve comprises the valve seat 1 that accommodates spool 2 in the inner chamber of the big valve film 3 that is fixed on the spool 2, big valve film 3 belows, and spool 2 walls of described big valve film 3 belows are provided with the flow control groove 13 that communicates with spool 2 inner chambers; Be fixed with the pulling block 11 of downward extension on the described magnet steel 8, spool 2 outer walls of these pulling block 11 tops are provided with the block of outside protrusion, leave the gap between described pulling block 11 and the block.When passing to field current in the electromagnetic coil 6, magnet steel 8 upwards slides, and little valve film 9 leaves throttle orifice mouth 10, and fluid enters throttle orifice mouth 10 through import 12, enters the inner chamber of spool 2, flows out from exporting 14 again.Because the diameter of the throttle orifice mouth 10 of described spool 2 upper end portions is less than the intracavity diameter of spool 2.So the fluid flow by little valve film 9 controls is very little.When field current continues to strengthen, the pulling block 11 that is fixed on the magnet steel moves up, run into the block on the spool 2 after, drive spool 2 and move on together, overcome the pressure of big spring 4 simultaneously, the big valve film 3 that is fixed in this moment on the spool 2 also moves on and then, exposes the flow control groove 13 on the spool 2, and fluid enters the inner chamber that flow control groove 13 enters spool 2 again through import 12, flow out through exporting 14, move greatly more on the spool 2, flow control groove 13 exposes many more, and flow is also big more.Because the aperture, bottom of described spool 2 inner chambers is greater than the inner chamber aperture on top, so the time fluid that flows through through throttle orifice mouth 10 just very little.In addition, spool 2 outer walls of big valve film 3 tops are with the big spring 4 of compression, and the upper end of this big spring 4 withstands on the internal chamber wall bump of valve body 5, and the lower end withstands on the outer wall bump of spool 2, can improve the stability of flow like this.
