Advection valve and water purifying and drinking system with same

Abstract

The invention relates to an advection valve. The advection valve comprises a valve body. A raw water inlet end, a pressure limiting water outlet end, a flow distribution water inlet end and a flow distribution water outlet end are arranged on the valve body. An internal portion of the valve body is provided with a pressure limiting cavity for connecting the raw water inlet end and the pressure limiting water outlet end, and a flow distribution cavity for connecting the flow distribution water inlet end and the flow distribution water outlet end. The flow distribution cavity is provided with anadvection water outlet end, the pressure limiting cavity is provided with an advection water return end, and the advection water outlet end and the advection water return end are provided with one-way valve components used for limiting water from flowing from the advection water outlet end to the advection water return end. A pressure limiting device is arranged on the pressure limiting cavity, and a flow distribution device is arranged between the flow distribution water inlet end and the flow distribution water outlet end. The invention also relates to a water purifying and drinking system.The system comprises a water purifying device, a heating device, a hot water outlet device and the advection valve. A water purification device is connected with a heating device through the advection valve to form a novel water purifying and drinking system, and redundant purified water can flow back to the water purification device.

Description

technical field [0001] The invention relates to the field of water supply systems, in particular to a water flow pressure limiting valve and a water purifier with the same. Background technique [0002] The water purifier can filter the tap water through the ultrafiltration filter element and RO membrane for people to drink. The water supply flow rate of the conventional water purifier is generally 1-1.5L / min. [0003] The water dispenser can heat water into warm water or boiled water for people to drink. Since the heating power of the water dispenser is relatively constant, when heating into warm water or boiled water, it is necessary to adjust the water supply flow to the heating element through a regulating valve or a water pump. Conventional drinking water machine, its water supply flow rate is generally 0.3-0.6 L / min. [0004] Since the water supply flow rate of conventional water purifiers is far greater than that of conventional water dispensers, conventional water d...

AI Technical Summary

Problems solved by technology

[0004] Since the water supply flow rate of conventional water purifiers is far greater than that of conventional water dispensers, conventional water dispensers are not suitable for direct connection with conventional water purifiers through pipelines, otherwise accidents such as pipe bursts and water leakage will easily occur.

In the prior art, when the two are connected, a water tank is generally installed on the water dispenser to reduce the water supply flow rate. When a water tank is used, the overall volume of the water dispenser will become larger
