Multi multi leaf valve installed in the main duct and branch duct, multi leaf valve, Shandong ventilation pipe processing in regulating valve is arranged on a main shaft of a driving electric actuator, switch on the power, adjust the actuator pointer position, the clockwise and counter clockwise rotation, and drives the main shaft on the valve leaf with the opening and closing.
When you press the button to manually uninstall the actuator, the manual control valve can be fully closed to fully open leaf position. With electric actuator of the multi leaf valve installed in the fresh air inlet at room air conditioning machine precision matching motor, fan power line and chain units, namely when the unit fan after the shutdown of the air pipe valve is also closed.
In the winter when used to avoid air machine after cold air into the heat exchanger unit of frozen water, but also because of the fire in the building, automatically cut off the fan power supply for fire control device, to prevent outside air into the air duct and increase the fire.
青海福彩网 The multi leaf regulating valve has many specifications, generally installed on the air duct, and the same size as the cross section of the air duct. When the manual multi leaf regulating valve is used, when the air volume is adjusted, the blade is adjusted to a certain angle, and the locking nut is used to fix the air quantity. Electric actuator should choose small size, high torque, high control accuracy, high reliability, easy installation of the product.
青海福彩网 The open closed multi leaf valve can be manual and electric two types, due to the use of the blade, flow is uniform, and can be manually adjusted through the connecting rod drives the blade to rotate, the flow of air flow, but also can make the air can not completely shut down. Because the blade edge is embedded with a sealing strip, the tightness can be ensured when the seal is closed, and the utility model has the advantages of small resistance and small air leakage.
Butterfly valve structure is simple, easy to operate, play the role of opening, closing or regulating the air volume, but more resistance to open, large leaf valve, usually installed in the air inlet into the precision room air duct. According to the structure of butterfly valve, there are two types of zipper and handle type.
