Classification of water-saving devices

Throttle and water-saving devices can be divided into automatic water-saving devices and fixed-hole throttle and water-saving devices. The automatic water-saving device adopts advanced dynamic pressure regulating and throttling technology, and automatically adjusts the circulation area of the water-saving device according to the water supply pressure, so as to ensure the water flow, pressure and flow of the water-saving device are basically stable, and provide suitable stable water flow for water use, so as to realize efficient water saving and improve the comfort of water use.

There are two kinds of automatic water-saving devices on the market:

One is a Korean water saver applying the patented technology of "automatic tap water flow regulating device" in Korea (this technology has applied for invention patent and utility model patent in China at the same time, and the utility model patent has been authorized);

One is Qichang water saver, which uses its patented technology of constant pressure and constant current.

They have the same principle, similar effect and different structure.

South Korea's water saver has only one installation method, that is, embedded installation method;

Its constant water-saving device has embedded installation mode and standard threaded connection installation mode. The traditional variable diameter throttling technology is characterized in that the circulation area of water-saving device is fixed, and the flow rate is directly proportional to the water pressure, that is, the contradiction between normal water use under low water pressure and effective water saving under high water pressure cannot be reconciled.
