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.

The first embodiment is as follows:

referring to fig. 1-2, a manual solenoid directional valve, including valve body 1, the one end top of valve body 1 is equipped with the thing passageway 2 of putting of L shape, it has case 3 that the level set up to put thing passageway 2 sliding connection, it has movable rod 4 of vertical setting to put thing passageway 2 internal rotation, the well upper side lateral wall of movable rod 4 is fixed with roof 5, install bellows 6 between roof 5 and the outer wall of valve body 1, the bottom cover of bellows 6 is located the top end opening part of putting thing passageway 2, the bottom of movable rod 4 is equipped with the perpendicular cross-section and is the thing groove of putting of door font, it all is equipped with the recess to put both sides wall bottom of thing groove, it is connected with dead lever 7 all to rotate in the recess, two dead levers 7 are fixed in on the both ends wall of case 3 one end respectively, it is connected with dwang 8 all to rotate on the both sides inner.
