Description
Technical field
The utility model belongs to electronic component technology field, and in particular to a kind of energy-saving electromagnetic valve.
Background technology
Usual magnetic valve is directly directly controlled by relay or power tube, and substantial amounts of heat, electromagnetism can be produced by working long hours
Valve is in the condition of high temperature for a long time, has a strong impact on its service life.
Utility model content
The utility model is directly controlled mainly for magnetic valve by relay or power tube, is also easy to produce heat, influences to use
A kind of the problem of life-span, there is provided energy-saving electromagnetic valve.
The utility model is for the technical scheme taken that solves the above problems：
A kind of energy-saving electromagnetic valve, including magnetic valve, it is characterized in that also include relay and constant-current source circuit module, it is described after
Electrical equipment is connected with power supply, and the normally-closed contact of relay is connected with the power input of constant-current source circuit module, relay it is normally opened
The output of contact and constant-current source circuit module is connected after being connected with magnetic valve.
The utility model uses above-mentioned technical proposal, and relay normally closed contact connects with the input of constant-current source circuit modular power source
Connecing, relay normally open contact and the output of permanent constant-current source circuit module are connected with magnetic valve, during system energization, relay opening, this
When power supply magnetic valve is connected to by relay normally open contact, open magnetic valve, after about 5 seconds, relay is stopped, power supply
Constant-current source circuit module is connected to by relay normally closed contact to power for it, constant-current source circuit module output very little is powered
Magnet valve continues to keep the electric current of working condition, and constant-current source circuit module output current is adjustable, to meet different size magnetic valve work
It is required.Therefore, the utility model can reduce magnetic valve power consumption, reduce its heating, extend its service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
