Abstract

The invention discloses a high-pressure-resistant electric-hydraulic control ball valve which is composed of two main modules including a ball valve body and an electric-hydraulic actuator. The electric-hydraulic actuator is composed of an electric-hydraulic actuating mechanism and a control system; the electric-hydraulic actuating mechanism comprises a motor, an oil pump, an oil tank, a hydraulic cylinder and an actuating mechanism; the control system comprises an electrical control system and a hydraulic control system; the ball valve body comprises a valve body, a ball body, an end pipe and a valve rod; the actuating mechanism is arranged at the upper portion of the valve body, is connected with the upper end of the valve rod, and can drive the valve rod to rotate; the hydraulic cylinder is fixedly connected to one side of the actuating mechanism; the oil tank is fixedly connected to one side of the actuating mechanism, and the oil tank is provided with the motor and the oil pump; and the hydraulic control system is arranged on the oil tank or the actuating mechanism. Further improvements are that the electric-hydraulic actuating mechanism further comprises a valve location transmitter; the motor is a servo motor; and elastic sealing structures are arranged on the two sides of the ball body. The high-pressure-resistant electric-hydraulic control ball valve is compact in structure, easy to install and debug, low in manufacturing cost, reliable and durable in elastic self-sealing, resistant to high pressure and long in service life.

Description

technical field [0001] The invention relates to a valve, in particular to an electro-hydraulic regulating ball valve. Background technique [0002] Electro-hydraulic regulating ball valves are widely used in process pipe networks and key equipment control systems in industries such as electric power, metallurgy, petroleum, petrochemical, and natural gas. The existing electro-hydraulic regulating ball valve is composed of two modules: the ball valve body and the electro-hydraulic actuator. The electro-hydraulic actuator is composed of an electro-hydraulic actuator and a control system. , The control system includes an electrical control system and a hydraulic control system, in which the oil pump and the oil tank are set in a huge independent external oil supply source. The electro-hydraulic regulating ball valve with this structure has a huge structure, complex installation and debugging, and high manufacturing cost. Contents of the invention [0003] Aiming at the defic...
