Abstract
The utility model relates to a low-power consumption motor valve, which comprises a valve body (1). a front sealing valve plate (2), a on-off valve plate (3), and a rear inverse press valve plate (4) which are connected by a center shaft (14) are arranged in the valve body (1), and valve plate groups are sealed by static surfaces. Both sides of the sealing surface of the on-off valve plate (3) are respectively provided with grooves (13), or the grooves (13) are arranged on the sealing surfaces of the front sealing valve plate (2) and the rear inverse press valve plate (4) which are adjacent to the on-off valve plate (3). Thus, friction force among the valve plates is reduced, and force moment is reduced. A circle annular groove (16) is arranged on the rear inverse press valve plate (4), and is communicated with the inlet end of the valve body (1) by an inverse press pipe (9). Thus, the pressure of an inlet end on the on-off valve plate (3) is counteracted to obtain the goal of free opening and closing under large pressure. By adopting a reflective sensor (10) and a correlative sensor (11) or arranging an angular displacement sensor (21) on the valve body (1), the goal of flow quantity adjustment and control is realized, and similarly the utility model can also exactly position and judge the opening and the closing of the low-power consumption motor valve.
