Abstract
The utility model relates to a self-maintaining solenoid valve, which comprises a main valve, a valve-opening position switch, a valve-closing coil and a valve-closing position switch. A clamping block mechanism is arranged between the valve-opening position switch and the valve-closing position switch, a valve-opening coil is arranged on the lower portion of the valve-closing coil, a movable iron core is arranged close to the valve-opening coil, an auxiliary valve is arranged on the lower portion of the movable iron core, and the main valve is arranged on the lower portion of the auxiliary valve. The self-maintaining solenoid valve adopts a valve opening and closing double-coil structure, can be electrified instantly, and is safe, energy-saving and reliable in sealing.
Description
Technical field
The utility model relates to a kind of solenoid valve, is specifically related to a kind of self-holding electromagnetic valve.
Background technique
Along with the development of society, people require increasingly high to the control technique of urban duct, therefore, the technical requirements of solenoid valve are also increased thereupon, and mostly in the market is open and close valve single coil structure forms, and obvious inadequately on energy-conservation, sealability is also obvious inadequately.
Summary of the invention
The utility model has overcome the deficiency of existing technology, has proposed a kind of self-holding electromagnetic valve, and said solenoid valve adopts open and close valve two coil configuration, and instantaneous energising, energy-saving safe, sealing are reliable.
The technological scheme of the utility model is: a kind of self-holding electromagnetic valve; Comprise main valve, drive the valve position switch, close valve coil and close the valve position switch; Be provided with fixture block mechanism driving the valve position switch and close between the valve coil, be out valve coil, near opening valve coil, be provided with moving iron core in the bottom of closing valve coil; Bottom at moving iron core is provided with auxilliary valve, and said main valve is positioned at the bottom of auxilliary valve.
Said moving iron core and auxilliary valve run through through a valve rod, on said valve rod, are provided with a handle.
Said pass valve position switch is arranged on out the next door of valve position switch.
The utlity model has following beneficial effect:
1) the utility model adopts open and close valve two coil configuration, instantaneous energising, energy-saving safe.
2) the utility model adopts the mechanical fixture block locking framework of flexibility and reliability, good reliability.
3) the utility model adopts special efficacy valve seal material, and sealing is reliable.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Accompanying drawing is the utility model master TV structure schematic representation.
Among the figure, 1, drive the valve position switch; 2, fixture block mechanism; 3, close valve coil; 4, open valve coil; 5, close the valve position switch; 6, wiring base; 7, moving iron core; 8, valve rod; 9, auxilliary valve; 10, main valve; 11, handle.
Embodiment:
Shown in accompanying drawing, the utility model comprises main valve 10, drives valve position switch 1, closes valve coil 3 and closes valve position switch 5, and said pass valve position switch 5 is arranged on out the next door of valve position switch 1.The next door of valve position switch 5 is provided with wiring base 6 in said pass.Be provided with fixture block mechanism 2 driving valve position switch 1 and close between the valve coil 3, be out valve coil 4, near opening valve coil 4, be provided with moving iron core 7 in the bottom of closing valve coil 3; Be provided with auxilliary valve 9 in the bottom of moving iron core 7; Said moving iron core 7 is run through by a valve rod 8 with auxilliary valve 9, and valve rod 8 extends through the top of fixture block mechanism 2, on said valve rod 8, is provided with a handle 11; Handle 11 is located at the below of moving iron core 7; When the screw device on solenoid valve top goes wrong, but handle 11 hand controls guarantee the solenoid valve proper functioning.Said main valve 10 is installed in the bottom of auxilliary valve 9.
Working principle is:
When opening valve coil 4 momentary connection power supplys, moving iron core 7 is by adhesive, and auxilliary valve 9 is unlocked, and so just makes the upper and lower chamber of main valve 10 produce pressure reduction, and main valve 10 is unlocked, and accomplishes the valve process of opening, and keeps opening the valve state by fixture block mechanism 2; When needs closed valve, the power supply of valve coil 3 was closed in momentary connection, made the lock ring of fixture block mechanism 2 throw off, and under the effect of Returnning spring, closed auxilliary valve 9 earlier and closed main valve 10 again, accomplished the valve process of closing.
Claims (3)
