Abstract

The invention relates to a liquid level control system. The liquid level control system comprises a vacuum drain valve, a liquid level pressure sensor, and a pneumatic controller which is connected with the liquid level pressure sensor and used for controlling opening and closing of the vacuum drain valve; the pneumatic controller comprises a shell, an air inlet system arranged in the shell, a vacuum source pressure stabilizing system, and a control system which achieves communication and blocking of air and vacuum; and the control system comprises a power assembly which is driven and controlled by the liquid level pressure sensor, an execution assembly which directly drives the vacuum drain valve to be opened and closed, and a manual inspection assembly used for fault detection. The liquid level control system is mainly composed of the three core parts of the liquid level pressure sensor, the pneumatic controller and the vacuum drain valve, and is applied into a vacuum well system toachieve discharge of wastewater, according to the liquid level control system, the pneumatic controller is driven by a water level signal detected by the liquid level pressure sensor to control opening and closing of the vacuum drain valve, and an integrated design mode is adopted for the pneumatic controller, so that the overall structural design is compact and reliable.

Description

technical field [0001] The invention relates to the technical field of liquid level control in the vacuum sewage continuous collection, temporary storage and periodic delivery system, wherein the vacuum sewage continuous collection, temporary storage and periodic delivery system is a vacuum well system, which has a vacuum drain valve for periodic It is a temporary sewage collection tank for sewage discharge, and can transport the sewage in its sewage collection tank to the downstream vacuum collection pipeline network. The whole system is controlled by the control device of the pressure difference drive control method through the change of the liquid level, and is used to To realize the sewage discharge in the sewage collection tank, the present invention particularly relates to a liquid level control system. Background technique [0002] Vacuum domestic sewage collection belongs to a state-of-the-art sewage collection technology, which transports domestic sewage from buildi...
