Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] 1. In Fig. 1 and Fig. 2, the normally closed valve core is that a pair of resetting permanent Magnets (7) and (9), a reset permanent magnet (7) is connected with the moving plate permanent magnet (5) through the support frame (6), and a reset permanent magnet (9) is connected with the pipe wall (1) of the ceramic core straight-through valve connected.
[0034] Also can be on the tube wall (1) of ceramic core straight-through valve, in the rotation range of reset permanent magnet (7) that links to each other with moving plate permanent magnet (5), concave-convex surface is set, and a convex surface is set on reset permanent magnet (7). point, cooperate with the concave-convex surface to achieve the purpose of limiting the switch.
[0035] In Fig. 1 and Fig. 2, (2) is the stator of the normally closed spool, (4) is the permanent magnet on the control ring of t...
