Reverse osmosis (RO) automatic pressurization device and RO automatic pressurization water storage tank

Abstract

The invention relates to pressurization devices and water storage tanks, specifically to an RO automatic pressurization device and an RO automatic pressurization water storage tank. The RO automatic pressurization device is connected to the back of an RO permeator, and internally consists of a pure water chamber and a waste water chamber separated by an elastic diaphragm. The pure water chamber is equipped with an upper water inlet and an upper water outlet, while the waste water chamber is provided with a lower water inlet and a lower water outlet, and the inside of the waste water chamber is provided with a time-delay switch mechanism. The lower water outlet is equipped with a valve plug controlled by the time-delay switch mechanism. The lower surface of the elastic diaphragm is provided with a diaphragm handle, which drives the time-delay switch mechanism, and the elastic diaphragm moves under the pushing of differential pressure inside the waste water chamber and the pure water chamber. The RO automatic pressurization water storage tank is connected to the back of the RO automatic pressurization device, and is internally provided with an air bag, which divides the water storage tank into a water storage chamber and a pressure chamber precharged with a gas. The pure water in the RO permeator enters the water storage chamber after pressurization by the RO automatic pressurization device. The RO automatic pressurization device of the invention increases the feed water pressure of the RO automatic pressurization water storage tank, has a great water-making amount, and saves water resources.

Description

technical field [0001] The invention relates to a supercharging device and a water storage tank, in particular to an RO automatic supercharging device and an RO automatic supercharging water storage tank. Background technique [0002] As we all know, pure water systems are widely used in households and small commercial places such as bars, coffee shops, medical laboratories, offices, etc. The taste of pure water is more sweet when drunk directly, and it is used in humidifiers, steam irons, beauty instruments, medical experiments, etc. There will never be scale, so the range of use is very wide. RO is the abbreviation of Reverse Osmosis in English, and it means reverse osmosis in Chinese. Generally, water flows from the low-concentration side to the high-concentration side. Once the water is pressurized, it will flow from the high-concentration side to the low-concentration side, which is the so-called reverse osmosis principle. This technology is generally called RO technol...
