Dual-liquid-level controller

Abstract

The invention relates to a dual-liquid-level controller. The dual-liquid-level controller comprises a liquid container provided with a liquid discharge port and a control container arranged therein, and an exhaust float ball valve is arranged between the liquid container and the control container. A valve air inlet and the side wall of the control container are connected. A position-adjustable high-liquid-level control float valve is arranged in the control container. The liquid inlet of the valve is connected with external liquid through the side wall of the control container. According to the invention, when the liquid-level controller operates, the opening and closing of a liquid inlet valve is controlled by the adjustable high-liquid-level control float valve; the liquid inlet valve is closed when the liquid level reaches a high liquid level line; at the moment, the control container matches the exhaust ball valve, so that the high-liquid-level control float valve is closed when the liquid level drops after high liquid level; at low liquid level, the closed state of the liquid inlet valve is relieved; the liquid inlet valve is re-opened, and the liquid is from low level to high level again; the process is repeated to control high and low liquid levels of the liquid discharge port; and the dual-liquid-level controller has the advantages of simple structure, easy material and low cost.

Description

technical field [0001] The present invention relates to a liquid level control container. Background technique [0002] The existing adjustable dual liquid level depth controllers are mostly realized by using pumps (or solenoid valves) and related control circuits. For example, an electronic dual liquid level controller has high liquid level control accuracy, but a complex structure. Due to the existence of the circuit, the cost of the entire controller is also relatively high, and the power consumption and reliability are low. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide an adjustable dual liquid level controller which can be controlled without using a circuit. [0004] The technical scheme of the present invention is as follows: a dual liquid level controller includes a liquid container, a control container located in the liquid container, and the bottom of the control container communicates with the liquid container; An exhaust f...
