The emergent quick action emergency valve of function of opening has

The utility model provides an emergent quick action emergency valve of function of opening has, including valve gap, disk seat, cylinder, spring baseboard, compression spring and emergent opening device, the drive of said cylinder said valve gap is relative the disk seat is opened or is closed, compression spring is provided said valve gap with do between the spring baseboard the valve gap provides the restoring force that resets. Open under the state emergent, emergent opening device is provided the bottom of said cylinder, emergent opening device roof pressure thereby the piston of cylinder drives said valve gap is relative said disk seat is opened. The utility model discloses an emergent quick action emergency valve of function of opening has cylinder when the vehicle is unloaded is out of work, and emergent opening device withstood the cylinder case this moment, drove the valve gap rising and opened the quick action emergency valve to play emergent opening, do not hinder and normally unload. The utility model discloses an emergent quick action emergency valve of function of opening has just not need not the manpower support with the medium contact at the emergent in-process of opening, and operation process is simple and convenient reliable.
