In order to overcome defect of the prior art, the utility model is achieved by the following technical solution: a kind of liquid leak-proof control gear preventing after valve invalidation, comprise: the first pipeline, on described the first pipeline, machinery valve is installed, the side that described machinery valve liquid flows into end is provided with electromagnetic valve, one side order of described machinery valve liquid outflow end is provided with the first current potential contact and the second current potential contact, described the first current potential contact and the second current potential contact maintain spacing and are arranged on the insides of pipes wall of described the first pipeline, at least be provided with insulator in the joint of described the first current potential contact and described the first pipeline, described the first current potential contact is connected with the potential comparator that is arranged on described the first pipeline external with the second current potential contact, described potential comparator and timer, power supply is connected with electromagnetic valve.
Further, described machinery valve is provided with the linkage that makes described the first current potential contact and described power circuit be communicated with or disconnect.
Further, described linkage is key switch.
Further, described linkage is contact type switch.
Further, described power supply is provided with switch.
Further, described the first pipeline is horizontal.
Further, described the first pipeline is communicated with second pipe in vertical position.
Further, described the second current potential contact is arranged on described second pipe madial wall.
Compared with prior art, superior effect is: the utility model has utilized the electric conductivity of water, detects the high characteristic of validity of leaking, fundamentally solve the problem of pipeline accidental water leakage, once which kind of leakage cause no matter generation water leakage phenomenon, be, can effectively stop leaking.
