Spool comprises valve core and spool bottom, and between spool bottom and spool, vertical direction is arranged with impeller shaft, jack shaft and output shaft in parallel.
Fault transmitter is provided with position switch, and position switch is contacted with output shaft by eccentric bushing.
Impeller shaft is provided with self-pressure drives impeller system, output shaft is provided with flashboard shutdown system, impeller shaft, between jack shaft and output shaft by transmission system transferring power.
Impeller shaft is connected with transmission system by centrifugal clutch.
Flashboard shutdown system comprises flashboard support, flashboard return spring, flashboard positioning work piece and locking nut, flashboard is fixed on output shaft by flashboard support, flashboard return spring and locking nut, and flashboard positioning work piece is connected with valve core in spool outlet port by screw.
Transmission system comprises actuation gear, intermediate gear and working gear.
Working gear one end is connected with output shaft by key, and the other end engages with intermediate gear.
The invention has the beneficial effects as follows: the present invention is a kind of pipeline burst self-closing valve, burst failure is there is by self-driven impeller identification pipe network by the unexpected increasing of pipe network rate of flow of fluid, impeller is moved through transmission system and passes to flashboard closedown executive system by actuation gear, rely on pressure and the flow velocity of pipeline itself, automatic connection valve flashboard drive system, emergency cut-off valve flashboard, and trouble signal is uploaded in time control centre's notice maintenance, after failture evacuation, by reset hand wheel system, valve flashboard is reset to opening state.
