A water replenishing device

Abstract

The invention discloses a water replenishing device, comprising a water supply box, a balance water box and a water storage tank; the water supply box, the balance water box and the water storage box are arranged in sequence from top to bottom; the water supply box and the balance water box pass through a first pipeline connected; the bottom of the balance water box is provided with a U-shaped water pipe; the balance water box is connected to the water storage tank through the second pipeline; the water storage tank is connected to the water supply box through the third pipeline; There is a water level switch; the bottom of the balance water box is provided with a water level pipe upward; the water level pipe communicates with the second pipeline; in the water supply device of the present invention, the balance water box ensures that the water supply device has been replenishing water; and because the bottom of the balance water box is set There is a U-shaped water delivery pipe, and the U-shaped water delivery pipe prevents liquid from flowing back through a liquid seal.

Description

technical field [0001] The invention relates to a water replenishing device, in particular to a water replenishing device used in a humidifying device of a constant temperature and humidity test chamber. Background technique [0002] The water replenishing device is used for adding water to the heating water tank, so that the heating water tank can output steam after heating the water. The water supply device generally includes a water supply box, a water supply, and a pipeline connecting the water supply box and the water supply. Only when the water level in the water replenishment box is lower than the water level switch in the water replenishment box, the water supplier replenishes water to the water replenishment box, and the water replenishment box replenishes water to the heating water tank, and the one-time replenishment will make the boiling water in the heating water tank not boil; at the same time, When replenishing water, the phenomenon of reflux often occurs. ...
