Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an example provided by the present solution: the utility model provides a make things convenient for power-off protection's solenoid valve, which comprises an outer shell 1, the bottom inner wall fixedly connected with backup pad 2 of shell 1, the top fixedly connected with magnetic path 3 of backup pad 2, the equal fixedly connected with first conductor 8 of the left and right sides inner wall of shell 1, the outside movable sleeve of first conductor 8 is equipped with insulating cover 7, the top sliding connection of insulating cover 7 has gag lever post 9, the right side of gag lever post 9 and the inner wall fixed connection of shell 1, the first electro-magnet 14 of the top inner wall fixedly connected with of shell 1, two sleeves 13 of the top inner wall fixedly connected with of shell 1, the equal movable sleeve in intracavity of sleeve 13 is equipped with cylinder 5, the equal fixedly connected with second conductor 4 in bottom of.

In this embodiment, insulating 7 tops of overlapping all are equipped with the slide rail, and the spout has all been seted up to the bottom of gag lever post 9, and the slide rail slides in the spout, and insulating 7 left side fixedly connected with iron plate 10 of overlapping.

In this embodiment, the cavity of the sleeve 13 is fixedly connected with a first spring 12, and the bottoms of the first springs 12 are fixedly connected with the top of the cylinder 5.

In this embodiment, a round hole is formed in the right side of the bottom of the housing 1, and a cylinder is fixedly sleeved inside the round hole.

In this embodiment, the bottom of the limiting rod 9 is fixedly connected with a second electromagnet 6, the right side of the second electromagnet 6 is fixedly connected with a second spring 11, and the other end of the second spring 11 is fixedly connected with the insulating sleeve 7.
