Negative-pressure intelligent sewage intercepting well
The invention discloses a negative pressure intelligent sewage intercepting well which comprises a sewage intercepting well body and a negative pressure water pumping device extending into the sewage intercepting well body, the negative pressure water pumping device comprises a water pumping pipe and a diaphragm valve arranged on the water pumping pipe, the diaphragm valve divides the water pumping pipe into a water pumping section and a vacuum section, and the vacuum section is communicated with a vacuum pump. The vacuum section and the working cavity of the diaphragm valve are controlled by an electromagnetic valve to be switched on and off, the action of the electromagnetic valve is controlled by a high-low liquid level pressure switch, the action of the high-low liquid level pressure switch is controlled by a pressure difference control pipe, and the pressure difference control pipe extends downwards into sewage of the sewage intercepting well body. Compared with a mechanical controller adopted for opening and closing a vacuum valve in the prior art, the pressure difference control pipe and the high-low liquid level pressure switch which are used in cooperation are adopted, the water level is converted into the air pressure so as to control the action of the electromagnetic valve, then the electromagnetic valve controls opening and closing of the diaphragm valve, the structure is simple, and stability and reliability are higher.
本发明公开了一种负压智能截污井，包括截污井本体、延伸入截污井本体中的负压抽水装置，所述负压抽水装置包括抽水管、设置在抽水管上的隔膜阀，隔膜阀将抽水管分成抽水段与真空段，真空段与真空泵连通。真空段及隔膜阀工作腔的通断由电磁阀控制，电磁阀的动作由高低液位压力开关控制，高低液位压力开关的动作由压差控制管控制，压差控制管向下延伸入截污井本体的污水中。相比于现有技术中真空阀启闭采用的机械式控制器，本发明采用配合使用的压差控制管、高低液位压力开关，将水位的高低转化为气压的高低，以控制电磁阀的动作，再由电磁阀控制隔膜阀的启闭，其结构简单，稳定性及可靠性更强。
