| 摘要 |
The device is designed for residential and public WCs. It has a simplified design and greater reliability. It reduces the noise level and leakage. The device consists of mains waterline (1) connected in its upstream end (2) to the mains network (3). The downstream end (4) is connected to a solenoid valve (5) made of a winding (6) and valve (7). In the front end (2) of the inlet pipeline (1) a stop valve (8) is fitted. In addition, the solenoid valve (5) by means of a feeding pipe (7) is connected to the toilet bowl (10). A circuit in series is connected parallel to the electric supply mains (11) consisting of winding (6) of the solenoid valve (5), winding (12) of the AC time relay (13) and button (14). An open contact (15) of the AC time relay (13) is connected (15 ) parallel to button (14). 4 claims, 1 figure
