Abstract

See full text

Disclosed is an energy-recycling hydraulic control main valve, which is provided with end covers, a valve core, a left one-way valve and a right one-way valve; the left one-way valve is composed of a left valve seat, a left cone valve core and a left spring; a conical surface of the left cone valve core is closely attached to a left conical surface of the valve core by the spring force; the right one-way valve is composed of a right valve seat, a right cone valve core and a right spring; and a conical surface of the right cone valve core is closely attached to a right conical surface of the valve core by spring force. The hydraulic main control valve can not only limit the falling speed of a piston, but use the potential energy generated by the gravity action on the piston, thereby achieving energy recycling.
