Liquid level adjusting device

Abstract

The invention discloses a liquid level adjusting device. The liquid level adjusting device is used for adjusting the liquid level in needed liquid storage equipment connected with the liquid level adjusting device. The liquid level adjusting device comprises a drain pipe, a telescopic pipe, a liquid level control mechanism and an adjustable fixing mechanism. The drain pipe, the telescopic pipe and the liquid level control mechanism are sequentially connected. The adjustable fixing mechanism is used for fixing the liquid level control mechanism. The drain pipe is communicated with the interior of the needed liquid storage equipment. The telescopic pipe and the liquid level control mechanism are vertically arranged beside the needed liquid storage equipment. An upper port of the liquid level control mechanism is an overflow opening. The adjustable fixing mechanism achieves liquid level adjustment of the liquid level control mechanism along with telescopic motion of the telescopic pipe. Through the telescopic pipe and the adjustable fixing mechanism matched with the telescopic pipe, the height of the liquid level control mechanism can be flexibly and conveniently adjusted, the liquid level in the needed liquid storage equipment can be controlled, the structure is simple, and operation is convenient. Through a float valve structure, opening and closing of the drain pipe are achieved, the liquid level can be controlled, and a water backflow prevention effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of liquid level adjustment and liquid backflow prevention. Background technique [0002] At present, the liquid level of anti-backflow valves, artificial wetlands, and water storage tanks in municipal drainage systems needs to be controlled to a certain level and prevent water backflow. And existing flap door is installed in flap door well, needs to build flap door well, and cost is high, and easy to deposit impurity to cause close not tight, and drainage is easy backflow backflow. Moreover, the maintenance space is small, and there is a problem that it is difficult to maintain. In addition, the existing overflow pipe is generally installed at the overflow level, and it is a one-time fixed installation. Once the installation is completed, the overflow liquid level cannot be adjusted, and the traditional overflow pipe does not have the anti-backflow function, which is prone to siphoning phenomenon of draina...

AI Technical Summary

Problems solved by technology

However, the existing flap door is installed in the flap door well, and the flap door well needs to be built, which is expensive, and is prone to deposit impurities, resulting in lax closure and easy backflow of drainage.

And the maintenance space is small, there is a problem that it is difficult to maintain

In addition, the existing overflow pipe is generally installed at the overflow level, and it is a one-time fixed installation. Once the installation is completed, the overflow liquid level cannot be adjusted, and the traditional overflow pipe does not have the anti-backflow function, which is prone to siphoning The phenomenon of drainage

[0003] It can be seen that the above-mentioned existing liquid level adjustment and anti-backflow device obviously still have inconvenience and defects in structure, method and use, and need to be further improved urgently.
