Liquid level regulating device and liquid level regulating method

Abstract

The invention discloses a liquid level regulating device and a liquid level regulating method. The liquid level regulating device comprises a main valve (5), a control device, a liquid level meter (13) and a transmitter (12), wherein the main valve (5) is used for being connected into a liquid supply pipeline (4); the control device is used for controlling the main valve; the liquid level meter (13) is used for measuring the liquid level of a liquid storage device (9); the transmitter is electrically connected between the liquid level meter and the control device, a liquid level signal measured by the liquid level meter is converted into a control signal through the transmitter, and the transmitter is used for transmitting the control signal to the control device. The liquid level signal is converted into the control signal through the transmitter after the liquid level is measured by the liquid level meter of the liquid level regulating device, the control device is used for controlling the opening or closing of the main valve according to the control signal, the specific liquid level of the liquid storage device can be intuitively reflected by the liquid level meter, and meanwhile the liquid level return different can be set for the control device according to practical requirements, so that frequent action of the main valve is avoided.

Description

technical field [0001] The invention relates to the field of liquid level adjustment, in particular to a liquid level adjustment device and a liquid level adjustment method. Background technique [0002] Traditionally, the liquid level adjustment of the liquid storage device is generally adjusted by a remote control float valve. The remote control float valve includes a main valve 5, a float ball 8 and a float pilot valve 6. On the liquid supply pipeline 4 of the liquid, the floating ball 8 is arranged in the liquid storage device 9 , the main valve 5 includes a control chamber 51 and a valve 52 , and the opening or closing of the valve 52 is controlled by the change of the hydraulic pressure in the control chamber 51 . [0003] figure 1 Shown is a schematic diagram of a traditional liquid level adjustment device. When the water level in the liquid storage device 9 is lower than the set height, the floating ball 8 falls and the floating ball pilot valve 6 opens, and the liq...

Problems solved by technology

[0004] However, the float 8 cannot visually reflect the liquid level of the liquid storage device 9, and when the float 8 breaks down, the staff cannot find out in time, resulting in the overflow of liquid in the liquid storage device 9, which can only be recovered by closing the manual shut-off valve 1 after discovery. Stopping the liquid supply will pollute the working environment and cause economic losses, and the floating ball 8 is installed in the middle of the liquid storage device 9, resulting in inconvenient maintenance when the floating ball 8 fails

Moreover, since the opening or closing of the main valve 5 of the traditional liquid level control device is controlled by the position change of the float 8, the main valve 5 will open or close if the position of the float 8 changes slightly, and the main valve 5 Frequent actions shorten the service life of the main valve 5
