Further, described water pipeline also comprises a bore passages, its bore passages is a kind of dual torus runner be made up of outer shroud runner and inner ring runner, outer shroud runner and inner ring runner form sealed spacer by a blanking cover, blanking cover is arranged a water intake outer shroud runner to be formed with inner ring runner be communicated with, outer periphery and the blanking cover water inlet of blanking cover are provided with O-ring seal, and intake tunnel is connected with outer shroud runner, and exhalant canal is connected with inner ring runner.
Further, the pin-lift arrangement of described on-off component mainly includes the movable valve rod for blocking intake tunnel and exhalant canal current, the elasticity reset device that drive activity valve rod is up and down, its elasticity reset device is according to the floating of reaction component thus the stream of promotion activity stem precludes intake tunnel and exhalant canal.
Further, described on-off component also includes the valve rod body being set in movable stem outer circumference, and valve rod body is also provided with the movable valve rod buckle for restraint valve rod downstream position, valve rod body is fixed on positioning seat.
Further, the magnetic means that described reaction component mainly comprises a ball float and is arranged on ball float, on-off component is provided with the magnetic force reaction device linked with magnetic means mutual induction.
Further, described magnetic means is a kind of magnet, and the magnetic force reaction device that on-off component is arranged produces with magnet the heteropole magnet that there is a natural attraction between the sexes.
Further, the underpart of described positioning seat is a kind of fence structure of hollow out, and ball float, when water level rises floating, is undertaken spacing by the underpart of positioning seat.
Further, reaction component also drives a warning device to send alarm signal when water level rises, described warning device is a kind of magnetic reed switch, and the trigger position of this magnetic reed switch is corresponding with the trigger position of on-off component.
Further, the interface end of described intake tunnel, exhalant canal and water pipe is respectively fitted with the quickly jointed tubular workpieces be made up of O-ring seal, quick-connecting plate, claw.
The beneficial effect of float type leakproof switch of the present invention is: reaction component rises or declines along with how much formation of lower cover housing internal water accumulation, thus interlock on-off component blocks or the stream of open water pipeline, reaches the object stoping and reveal; Send alarm signal by warning device to user simultaneously, user can judge machine problem according to the display of alarm signal, thus change corresponding component, what adopt due to reaction component is floating structure, makes this float type leakproof switch also reusable when not renewal part.
