For achieving the above object, overall conception of the present utility model is when standpipe inside and outside differential pressure generation unusual fluctuations, and sensing device is collected signal, transmits action command to energy storage equipment; The energy storage equipment transmitting power excites the actuating mechanism operation to hydraulic mechanism, realizes that seawater is filled into device inside, balance external and internal pressure protection drilling safety.
A kind of offshore oil filling type drilling safety valve, it has upper flange, intervalve, energy storage equipment, sensing device, cylindrical shell, motion, lower flange, flange bolt; The sensing device of collecting standpipe external and internal pressure abnormal signal is installed on the intervalve and with energy storage equipment and is connected, the energy storage equipment transmitting power is to motion, and motion is installed in the drive valve switch that can move up and down on the cylindrical shell and realizes that seawater is filled into device inside.
Be distributed with auxiliary line on the upper flange of drilling safety valve and the lower flange circumference.Auxiliary line comprises that throttling/kill line, mud supercharging pipeline, hydraulic pressure transfer line, chemical agent inject one or more combination of pipeline.
The safety valve positioner is housed on intervalve, and safety valve positioner one end is connected with energy storage equipment, and an other end is located on intervalve.
Energy storage equipment is by hydraulic mechanism transmitting power motion.
Motion is positioned at the safety valve cylindrical shell, and motion one end is connected with energy storage equipment by hydraulic mechanism and the switch of realization to water intaking valve on the safety valve cylindrical shell that move up and down in the safety valve cylindrical shell.
Advantage of the present utility model: topology layout is reasonable, connect quick, response time weak point, good stability, can be in the advantage of offshore boring island control etc.Can be applied to deep water, super deepwater drilling operating environment well, have good Practical Performance and higher macroeconomic performance.In deepwater drilling operation safety device few in number, its design feature, mode of occupation have clear superiority.
