Claim:
A valve wrench safety system ( 100 ) for preventing the valve wrench from slipping off a valve ( 500 ), the system comprising: (a) a housing ( 110 ) having a top side ( 115 ) with an opening ( 120 ), a bottom side ( 125 ), a front side ( 130 ) and a lever-control-side ( 135 ) having a sliding slot ( 140 ) wherein the sliding slot runs from the top side to the bottom side, the front side having a first front side edge ( 145 ) and a second front side edge ( 150 ); (b) a chamber ( 155 ) disposed within the housing, the chamber opens up to the opening on the top side of the housing; (c) a lock slide bar ( 160 ) sized to fit through the opening and sized to slide in and out of the chamber; (d) a slide lever ( 165 ) attached to and extending outwardly away from the lock slide bar, the slide lever protrudes through the housing via the sliding slot; wherein pushing the sliding lever upward towards the top side causes the lock slide bar to extend upward from the top side and wherein pushing the sliding lever downward towards the bottom side causes the lock slide bar to retract into the chamber; (e) a first arm ( 170 ) attaching to and extending from the first front side edge away from the housing, the first arm has a first distal end ( 175 ) with screw threading; a second arm ( 180 ) attaching to and extending from the second front side edge away from the housing, the second arm has a second distal end 185 with screw threading, wherein the first and second arm extends outwardly in the same direction; (f) a plate ( 190 ) having a first hole ( 195 ) to accommodate a penetration of the first distal end of the first arm, and a second hole ( 200 ) to accommodate a penetration of the second distal end of the second arm, wherein the system is secured to a valve wrench ( 300 ) at a wrench rod region ( 305 ) adjacent to a curve head portion ( 310 ) of the valve wrench, by sandwiching the wrench rod region between the front surface of the housing and the plate wherein the first arm and second arm wrap around the wrench rod region; wherein a first wing nut ( 400 ) is screwed onto the threading of the first arm and a second wing nut ( 405 ) is screwed onto the threading of the second arm thereby pushing the plate against the wrench rod region; wherein to prevent the valve wrench from slipping off, the lock slide bar is pushed to extendly upward from the top side.
