| 摘要 |
<p>The present invention relates to a continuous fluid discharge apparatus comprising a fluid storage tank; a pump which is connected to the fluid storage tank, sucks the fluid stored in the fluid storage tank and sends the fluid to a main pipe; a discharge valve which is installed between the pump and the main pipe and discharges the fluid stored in the fluid storage tank to the main pipe by opening and closing operation; and a control unit which converts a voltage signal applied to the discharge valve according to the required discharge rate of the fluid into a pulse width modulation (PWM) signal and controls the opening and closing time of the discharge valve according to the PWM signal. The continuous fluid discharge apparatus can discharge the fluid continuously regardless of required discharge rate of the fluid by controlling the opening time of the discharge valve according to the pulse width of the PWM signal.</p> |
