Like this, enter by water intake in the process that valve body flows out by water outlet again at tap water, water (flow) direction only at the fixed spool place through the very little setback of amplitude, therefore compared with prior art, the resistance of whole runner obviously reduces, even under the less situation of current, also can keep floating plug to be in opening state by hydraulic pressure, thereby can effectively prevent under the prerequisite of water clock stolen water, guarantee that the user can need to regulate water flow by the reality use.
The present invention further improves, and described fixed spool and floating plug opposing end faces be isolation pad fixedly, is shaped on magnetic penetrating hole on the described isolation pad, and described fixed spool and floating plug opposing end faces are shaped on the projection that stretches into magnetic penetrating hole.Like this, further guaranteed to have only when fixed spool and floating plug opposing end surface are contiguous, effective adhesive Shuttoff Valve, promptly ability throttle down when water clock stolen water situation takes place has only more effectively been avoided the retardance to small water flow.
