Liquid enters housing, and through liquid mouth and the liquid pass hole excessively of spool, spool does not have the pressure that liquid imbalance is brought in housing.Only have sealing ring to have friction during rotary handle, owing to sealing ring and spool contact area are little, during rotation, reduce frictional force.Described spool runner is connected.
Apparatus of the present invention are made up of two housings, and two parts spacing can adjust, between connection realize by two groups of positioning tables, there is the feature of internal liquid balance, and it is little to rub, rotation power-saving.
Beneficial effects of the present invention:
1. switching device is made up of two housings, manufactures and simplifies, and reduces mould requirement.
2. two housing spacing are adjustable, meet the use occasion that spacing is different；
3. internal employing pressure balance principle；
4. reducing spool contact area, rotatable handle is laborsaving.
