Hydraulic controlled casing valve for well cementing

The utility model discloses a hydraulic controlled sleeve tube valve for well cementing, which solves the problem that outer annular spaces of a sleeve tube can not be continuous sealed or one layer of the annular spaces can not be sealed at times. The utility model is characterized in that a pin can be opened by using ground pressure shear, and circulation and the well cementing can be reached through a circulation port; the pin can be closed by using the ground pressure shear, which causes a lower line of a closing sleeve and an opening sleeve to be sealed to seal the circulation port, and permanent spacing can be reached by using clamp springs. Compared with the prior art, the sleeve tube valve has the advantages that rubber plugs do not need to drill, well completion time is shortened, effectiveness is improved, etc.
