Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more particularly to a water treatment system capable of treating two different raw water sources (or water to be treated), such as cold water and hot water. Furthermore, this utility model's water treatment system can treat two different raw water sources, such as cold water and hot water, using a single fluid control valve. Accordingly, this utility model also further relates to a fluid control valve for use in a water treatment system. Technical Background

[0002] With increasing emphasis on health and concerns about water pollution, water treatment machines or systems have become common household appliances. Water treatment machines, especially household ones, are mostly installed in kitchens to treat water and obtain cleaner water. Furthermore, in the industrial sector, it may be necessary to treat two different types of raw water simultaneously to obtain the desired treated water.

[0003] Most existing technologies employ two different water treatment systems to treat two different types of raw water separately, obtaining corresponding treated water. The two types of treated water are then mixed (if necessary, for example, using a hot and cold water mixer) to obtain the final treated water for the intended purpose. Two different water treatment systems mean two water treatment devices and two fluid control valves, which not only increases the space required but also adds complexity to water treatment control. Utility Model Content

Accordingly, when the water treatment system according to this embodiment of the present invention is in the first forward washing operation state and the second forward washing operation state, first raw water flows in from the first water inlet 1105 and flows from the first raw water supply channel 10001 to the first water outlet 1106 of the valve body 11; second raw water flows in from the second water inlet 1107 and flows from the second raw water supply channel 10002 to the second water outlet 1108 of the valve body 11, so as to be supplied.

The first water outlet 1106 of the valve body 11 is provided; the conduction channel 1015 of the plane valve 10 is connected to the seventh channel 107 and the eighth channel 108 respectively, thereby forming a second raw water supply channel 10002 that is connected to the second water inlet 1107 and the second water outlet 1108 of the valve body 11 respectively, so that the second raw water can flow in from the second water inlet 1107 and flow from the second raw water supply channel 10002 to the second water outlet 1108 of the valve body 11 to be provided.

[0119] It is worth noting that when the planar valve 10 is in the first backwash working position and the second backwash working position, the sixth channel 106 of the planar valve 10 is connected to the first water inlet 1105 through the valve cavity 110 of the valve body 11, thereby forming the first raw water supply channel 10001, which is connected to the first water inlet 1105 and the first water outlet 1106 of the valve body 11 respectively. The seventh channel 107 and the eighth channel 108 of the planar valve 10 are connected through the conducting channel 1015, thereby forming the second raw water supply channel 10002, which is connected to the second water inlet 1107 and the second water outlet 1108 of the valve body 11 respectively. This allows the first and second raw water to be supplied directly without being treated by the first water treatment device 51 and the second water treatment device 52 when the planar valve 10 is in the first backwash working position and the second backwash working position. Furthermore, when the planar valve 10 is in the first forward washing position and the second forward washing position, the sixth channel 106 of the planar valve 10 is connected to the first water inlet 1105 through the valve cavity 110 of the valve body 11, thereby forming the first raw water supply channel 10001, which is connected to the first water inlet 1105 and the first water outlet 1106 of the valve body 11 respectively. The seventh channel 107 and the eighth channel 108 of the planar valve 10 are connected through the conductive channel 1015, thereby forming the second raw water supply channel 10002, which is connected to the second water inlet 1107 and the second water outlet 1108 of the valve body 11 respectively. This allows the first and second raw water to be supplied directly without being treated by the first water treatment device 51 and the second water treatment device 52 when the planar valve 10 is in the first forward washing position and the second forward washing position.
