Description
Technical field
The utility model is related to a kind of DC electromagnetic valve, more particularly to a kind of HVDC magnetic valve.
Background technology
In household electrical appliance, most magnetic valve is all using alternating current electromagnetic valve either DC electromagnetic valve.Alternating current
Magnet valve suction is small, and when electromagnetic core adhesive distance is more than 15mm, suction drastically declines, it is impossible to which lead agency is acted, moreover, handing over
Manifold solenoid valve electromagnetic noise after closure is big, and the comfort level of family life is had influence on to a certain extent.DC electromagnetic valve is (typically
Using low-voltage direct magnetic valve, below 36V), for alternating current electromagnetic valve, noise is smaller, suction is bigger, still, direct current
The suction of magnet valve still has the space further lifted.
Utility model content
The utility model provides a kind of DC electromagnetic valve with bigger suction.The utility model solves its technical problem
The technical scheme used is：
A kind of DC electromagnetic valve, including the coil holder of passage is formed there through above and below middle part, the electromagnetism of the coil holder surrounding is wrapped in
Coil, the electromagnetic core being movably arranged among the passage, in addition to it is arranged on the electromagnet core print seat of the channel bottom, the electromagnetism
Iron core forms connection-peg towards the electromagnet core print seat one end, on the end face of the electromagnet core print seat to should connection-peg be provided with groove；
Magnet coil energization, which produces magnetic field, makes the electromagnetic core move and be attached together with the electromagnet core print seat, simultaneously
The connection-peg is inserted among the groove.
The technical program is compared with background technology, and it has the following advantages that：
Directly DC electromagnetic valve is powered with commercial power rectification, in the conductive state, the electromagnetic core and the electromagnet core print seat
Attract each other, the electromagnetic core is produced movement, and the connection-peg is inserted among the groove.The electromagnetic core and the electromagnetism
When iron core base is inhaled together, adsorbed and connected by the fit system of connection-peg and groove, substantially increased the suction of the two and have
Adhesive distance is imitated, and reduces adhesive noise.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
