Pressure regulating type waste water ratio

Abstract

The invention discloses a wastewater ratio of pressure-adjustable type, which comprises a main value body (12) which is provided with a water inlet and a water outlet (21, 25), and a regulating chamber (26). The water inlet and water outlet are communicated through the regulating chamber. A pressure regulating component is mounted on the regulating chamber. The pressure regulating components comprise a value sleeve (6) and an elastic pulling block. Screws are arranged on the top of the value sleeve. The screw extends into the value sleeve and resists the elastic pulling block. The bottom of the elastic pulling block is provided with a sealed pad (11) for dealing and blocking the regulating chamber. The invention with a matched parameter is arranged on an RO prettified water machine and the pressure limitation force by adjusting the depth of the screw on the top. When being used, particularly, the changes generated by water net pressure or the output water pressure of a booster pump isbigger than the working pressure of the PO filming pipe, the high-handed compressed water which is over the pressure limited value opens the sealed chamber of the regulating chamber from the top of the water inlet chamber on the invented main value body, thus the water entering channel is run-trough. The water is drained from the water outlet and the pressure is automatically reduced.

Description

technical field [0001] The invention relates to the wastewater ratio in pure water equipment, in particular to a wastewater ratio with adjustable pressure. Background technique [0002] Among water appliances that use reverse osmosis technology for water purification, the pure water machine is a small factory that produces pure water. As shown in Figure 1, the purification system mainly includes activated carbon filter 1 (filter element I, filter element II, filter element III), booster pump 2, reverse osmosis membrane tube (RO membrane tube) 3 and waste water ratio 4 and other components. Since the pore size of the RO membrane in the RO membrane tube is only 0.0001-0.001 microns, most of the inorganic salts (including heavy metals), organic matter, bacteria, and viruses dissolved in water cannot pass through the RO membrane. As the core RO membrane tube, with the help of the pressurization of the booster pump at the front end of the RO membrane tube and the back pressure o...

Problems solved by technology

The traditional RO pure water machine technology cannot achieve constant or adjustable water pressure indicators. The actual working pressure of the RO membrane is difficult to stabilize. During use, the pressure is too high to cause the failure of the RO membrane or the phenomenon that the pressure is too low and the water yield is low.
