摘要（英）：

The utility model discloses a control execution mechanism for a liquid-controlled butterfly valve. The control execution mechanism comprises an oil tank, the liquid-controlled butterfly valve, an energy storage assembly, a first two-way cartridge valve, a second two-way cartridge valve, a third two-way cartridge valve, a first electromagnetic directional valve and a second electromagnetic directional valve. A first oil port and a second oil port of the liquid-controlled butterfly valve are connected with an oil return port of the oil tank. The energy storage assembly is connected with an oil outlet, the first oil port and the second oil port. The oil inlet end of the first two-way cartridge valve is connected with the first oil port, and the oil outlet end of the first two-way cartridge valve is connected with the oil return port. The oil inlet end of the second two-way cartridge valve is connected with the second oil port, and the oil outlet end of the second two-way cartridge valve is connected with the oil return port. The oil inlet end of the third two-way cartridge valve is connected with the second oil port, and the oil outlet end of the third two-way cartridge valve is connected with the energy storage assembly. The oil inlet end of the first electromagnetic directional valve is connected with the energy storage assembly, the oil return end of the first electromagnetic directional valve is connected with the control end of the first two-way cartridge valve and the control end of the third two-way cartridge valve, and the working end of the first electromagnetic directional valve is connected with the oil return port. The oil inlet end of the second electromagnetic directional valve is connected with the second oil port, the oil return end of the second electromagnetic directional valve is connected with the control end of the second two-way cartridge valve, and the working end of the second electromagnetic directional valve is connected with the oil return end of the first electromagnetic directional valve. The control execution mechanism for the liquid-controlled butterfly valve is high in regulation precision, reliable in movement and capable of guaranteeing the safe and continuous operation of a circulating water system.
