Water treatment method and device for water replenishment under constant pressure

Abstract

The invention discloses a water treatment method and a device for replenishing water at constant pressure. By using a controller, the pressure value in the constant pressure tank is divided into three intervals, that is, the pressure value in the constant pressure tank is below the first threshold, Between the first threshold and the second threshold and the normal value, after the second pressure gauge detects the pressure in the constant pressure tank, the controller judges that the pressure value detected by the second pressure gauge is below the first threshold, the second Between the first threshold and the second threshold or the normal value; use the water replenishment and constant pressure of the two delivery channels to ensure accurate replenishment of water into the constant pressure tank, and ensure the pressure value in the constant pressure tank at all times, so as to improve the user's confidence Satisfaction with the product.

Description

technical field [0001] The invention relates to the technical field of heating and air-conditioning water circulation, and in particular to a water treatment method and a device for replenishing water at constant pressure. Background technique [0002] The current heating and air-conditioning water system, in order to ensure that the highest point of the building can fully fill the circulating water without collecting air to terminate the cycle, often maintains the circulating return water at a specified pressure, so that the return pressure head 2-3 meters higher than the building height. To achieve this goal, the conventional method is to use a water replenishment and constant pressure system, that is, the replenishment pump continuously pumps water from the replenishment water tank to replenish water in the circulating water system to maintain the return caused by the lack of water in the circulating system due to running, popping, dripping, leaking or artificial water re...

To achieve this goal, the conventional method is to use a water replenishment and constant pressure system, that is, the replenishment pump continuously pumps water from the replenishment water tank to replenish water in the circulating water system to maintain the return caused by the lack of water in the circulating system due to running, popping, dripping, leaking or artificial water release. Water pressure drops, but the design results in poor user satisfaction
