    It is check valve with  large pressure drop , and it is arrow-type valve seal. It will shut down rapidly under the action of reverse circulation pressure and spring force within drilling tools, to cut off the channel within drilling tools and prevent blowout within drill tools. It can be reversed on the platform, or release its top open device and install it between drill pipe and drill bit to prevent the high pressure oil and gas blowing out from the drilling tools. A special release tool makes the valve in a normally open state and allows backflow going through. This release tool is installed in the float valve in advance and it can rapidly install the valve on the drill string when the first blowout signal in drill pipe is discovered as being pulled out of the well.
