AIR BYPASS VALVE DEVICE

Номер: WO2011114376A1
Принадлежит:

A mortise (31) is provided in any one of a case (3) and a valve assembly (5), and a mortise groove (8e) is provided in the other thereof, so that the case (3) and the valve assembly (5) are combined by mortise joint. Thus, the total height of a product can be maintained constant without being influenced by the characteristics (property) of the material of components. Further, effects such as reduction of the number of components, prevention of detachment of the valve assembly (5) during transportation can be obtained.

The prsent invention relates to a control method of valve. When the valve lift control signal from control unit is received by said invention, two windings of windings of the stepping motor can be excited, and the opening of valve can be regulated, and when the opening regulation of valve is completed, after a certain period of time, the excitation mode of stepping motor can be changed into single-phase excitation from double-phase excitation so as to provide a valve control method capable of inhibiting heating quantity and current consumption of winding when the rotation of stepping motor is stopped.
