In order to realize above-mentioned target, the present invention adopts following technological scheme: a kind of anti-theft antifreezing valve, comprise valve handle, valve rod, valve body and spool, it is characterized in that, also comprise the cipher anti-theft device be fixed on above described valve body, around valve rod and the anti-icer be positioned at outside described valve body, described cipher anti-theft device comprises code keypad, is positioned at the telescopic cavity of cipher anti-theft device and electronic switch latch mechanism, arranges projection in described telescopic cavity; Described projection is connected with described electronic switch latch mechanism; Described anti-icer comprises the thermal insulating material arranged from inside to outside be wrapped on described valve body, electric tracing thermal insulation band and Polypropylence Sheet.
Aforesaid a kind of anti-theft antifreezing valve, is characterized in that, described electronic switch latch mechanism by code keypad by key control.
Aforesaid a kind of anti-theft antifreezing valve, is characterized in that, the projection corresponding position of described valve rod and cipher anti-theft device is provided with recessed piece of annular.
Aforesaid a kind of anti-theft antifreezing valve, is characterized in that, when valve rod locks, projection stretches out described telescopic cavity, just in time snaps in described recessed piece.
Aforesaid a kind of anti-theft antifreezing valve, is characterized in that, when valve rod unlocks, projection retracts in described telescopic cavity.
Aforesaid a kind of anti-theft antifreezing valve, is characterized in that, described thermal insulating material is ramie cotton fabric or sponge, and described thermal insulating material applies antifreeze liquid, and described thermal insulating material is wrapped with ambroin film.
Aforesaid a kind of anti-theft antifreezing valve, it is characterized in that, described electric tracing thermal insulation band is the electric heating wire of charged pool, described electric tracing thermal insulation band is wrapped in outside the ambroin film of described thermal insulating material.
Aforesaid a kind of anti-theft antifreezing valve, is characterized in that, arranges helical rubber around the described valve rod being positioned at valve inner.
The beneficial effect that the present invention reaches: the present invention, by recessed piece of the projection of cipher anti-theft device, code keypad, electronic switch latch mechanism and valve rod corresponding position, effectively prevents valve from being opened by mistake and opens, have anti-theft function; When temperature is lower, the thermal insulating material of helical rubber, anti-icer, electric tracing thermal insulation band, effectively prevent valve by bursting by freezing.The present invention is rational in infrastructure, simple and practical, has anti-theft antifreezing effect.
