Liquid level control device, vacuum pumping and discharging system using same, and pumping and discharging method
The invention relates to a pipeline system for fluid delivery, and discloses a liquid level control device, a vacuum pumping and discharging system using the same and a pumping and discharging method.The liquid level control device comprises a vacuum pumping-suction pipe, an execution valve and a control valve, wherein an inlet of the vacuum pumping-suction pipe is inserted into the bottom of liquid in a liquid storage container; the execution valve is arranged on the vacuum pumping-suction pipe; the lower end of the control valve is inserted into the liquid storage container; when the liquidlevel of the liquid storage container is at a high position, the control valve enables an execution valve leather cup in the execution valve to be opened by introducing negative pressure so as to pump liquid, and when the liquid level is at a low position, the control valve enables atmosphere to be introduced into the execution valve leather cup in the execution valve so as to close the valve; and therefore, the liquid level is controlled for the vacuum pumping and discharging system. According to the liquid level control device, the vacuum pumping and discharging system using the same and the pumping and discharging method, parts which are in direct contact with solid-containing liquid or possibly splashed are not provided with any movable components, and cannot be stuck by fine particles to fail; and all automatic valves do not need electricity or instrument air, and are safer and more reliable than electric instruments and cheaper than pneumatic instruments.
本发明涉及一种用于流体输送的管道系统，公开了一种液位控制装置及使用该装置的真空抽排系统及抽排方法，液位控制装置包括入口插设在储液容器内的液体底部的真空抽吸管，设置在真空抽吸管上的执行阀，下端插设在储液容器内的控制阀；储液容器的液位处于高位时，控制阀使执行阀内的执行阀皮碗通负压从而开启并抽液，液位处于低位时，控制阀使执行阀内的执行阀皮碗通大气从而关闭阀门；从而为真空抽排系统控制液位。本发明中，与含固液体直接接触或可能溅到的部件无任何活动组件，不会被细小颗粒卡住而失效；本发明中，所有自动阀门不需要用电或仪表风，较电动仪表更安全可靠，较气动仪表更廉价。
