Abstract

The utility model relates to a micro-current control power-saving electromagnetic valve composed of a starting coil 7, a valve core 6 with a notch, a control coil 3, an iron core 2, a phosphor copper hook 5, an armature 4 and a soft magnetic boot 1. The utility model can instantly cut off a power supply and closes a valve when the power of a battery is off or a water card purchased by a user is used up; in addition, the utility model has the advantages of convenient control, power saving (only reaching scores of mw) and small noise, and overcomes the defects that the existing self-locking electromagnetic valve can not close the valve under the condition of no power.

Description

A kind of economize on electricity solenoid valve of little Current Control

The utility model relates to a kind of economize on electricity solenoid valve of little Current Control, belongs to field of energy-saving technology.

In existing technical field, solenoid valve is widely used in the industrial or agricultural as carrying out no accessory.But, limited the application of solenoid valve because there are shortcomings such as power consumption is many, intensification is high, noise is big in existing solenoid valve.Therefore designer of the present utility model had applied for the solenoid valve power-saving module, promptly added a power-saving module between the two ends of power of electromagnetic valve and solenoid valve, can reach the reduction power consumption.Overcome the shortcoming high, that noise is big that heats up.But when with family expenses IC-card water meter on distribution magnet valve when using dry cell power supply, above-mentioned module just can not meet the demands.Therefore, there are the solenoid valve or the impulse electromagnetic valve of the self-locking of employing band to address the above problem again.Though the solenoid valve of band self-locking economizes on electricity very much, when the user took out battery, solenoid valve just will be opened can't calculate water consumption.Change battery voluntarily if adopt lead sealing to be forbidden to open water meter, solenoid valve same after battery uses up so just will open forever and can't cut out again.

The purpose of this utility model can in time not cut off the electricity supply when to be that design is a kind of use water card dryelement cell, that have electricity or user to buy when battery to use up, the economize on electricity solenoid valve of a kind of easily new little Current Control of usefulness of throttle down and control.

Scheme of the present utility model is as follows: the utility model structure comprises starting coil 7 and is positioned at the spool 6 of starting coil.It is characterized in that above-mentioned spool 6 is for having the spool of groove, one control coil 3 is arranged above above-mentioned starting coil 7, center of control coil 3 cored 2 and phosphor-copper grab 5, the boss of phosphor-copper grab 5 upper ends and iron core 2 overlap joints, middle-end is fixed an armature 4, there is a grab lower end, and film magnetic boots 1 are fixed on a side of control coil 3 outsides.Control wiring of the present utility model composed as follows: starting coil DF1 (7), control coil DF2 (3) and circuit breaker J also connect.One end of one end and power supply joins, and its other end DF1 joins by K switch J1 and power-saving module CH98, DF2 and relay J directly and CH98 join, the other end of CH98 and the other end of power supply join.

The utility model control is opened when IC-card water meter output " I " easily, and " O " promptly closes.When taking out battery, user oneself also can close valve solenoid valve valve immediately.Shortcoming that can't Shuttoff Valve when having overcome existing self-locking electromagnetic valve and not having electricity.Power consumption little (only reaching tens milliwatts), noise are little.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the utility model structural drawing;

Fig. 2 is the utility model control circuit figure.

As shown in Figure 1, form the utility model by starting coil 7, control coil 3, soft iron magnetic boots 1, iron core 2, armature 4, phosphor-copper grab 5, the spool 6 that has a groove.The boss of phosphor-copper grab 5 upper ends is overlapped on the upper end of iron core 2, fixedlys connected with armature 4 in the middle part.The grab of phosphor-copper grab 5 lower ends is used for locking spool 6.When work, starting coil 7 energisings, spool 6 rise, valve open, meanwhile control coil 3 also electric, this moment, armature 4 was attracted to magnetic boots direction, also to mobile in the same way, grab blocks the groove of spool 6 to the phosphor-copper grab 5 of fixedlying connected with armature 4.Starting coil 7 outages after locking.Its feature is big current start, and electromagnetic force converts mechanical caging to, pins the spool that rises, and has in time cut off big current start coil power.Owing to added the CH98 power-saving module, kept micro-current work.Power consumption descends.

Control wiring work is as follows, as shown in Figure 2 when starting power connection, and relay J work, the closed starting coil DF1 of K switch J1 (7) work, spool 6 rises, and control coil DF2 (3) also works locking spool.After this, the relay J dead electricity, KJ1 disconnects, and control coil DF2 (3) keeps state because the control of CH98 enters economize on electricity, and general power disconnects back valve core and descends, and throttle down is finished week work.

Claims
