DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-3 As shown, an automatic switching water supply device for a pure steam generator 1 of a multi-effect distilled water machine comprises a pure steam generator 1, a raw water inlet of the pure steam generator 1 is connected to a multi-channel valve assembly 2, the multi-channel valve assembly 2 is respectively connected to a first-way purified water distribution point system 3 and a second-way purified water distribution point system 4, the first-way purified water distribution point system 3 and the second-way purified water distribution point system 4 are signal-connected to the pure steam generator 1.

[0021] The multi-channel valve assembly 2 comprises a water supply pipe 21 connected to the pure steam generator 1 , and the water supply pipe 21 far away from the pure steam generator 1 is respectively connected with a first inlet branch pipe 23 and a second inlet branch pipe 24 .

[0022] In detail, a first point-of-use valve 231 is provided on the first inlet branch pipe 23 , and a second point-of-use valve 241 is provided on the second inlet branch pipe 24 .

[0023] A safety automatic opening and closing valve 22 is provided on the water supply main 21 .

[0024] The purpose of setting the safety opening and closing valve 22 is to be able to timely shut off the water supply when the pure steam generator 1 generates the maximum amount of water, or to quickly shut down, quickly open and close control and emergency control during safety inspection when starting.

[0025] Specifically, the first point-of-use valve 231 and the second point-of-use valve 241 are pneumatic valves.

[0026] In detail, the first purified water distribution point system 3 is connected to the first point valve 231 and is pneumatically opened and closed, and the second purified water distribution point system 4 is connected to the second point valve 241 and is pneumatically opened and closed.

[0027] Preferably, the first point-of-use valve 231 and the second point-of-use valve 241 are both connected to external pneumatic equipment.

[0028] The first point-of-use valve 231 and the second point-of-use valve 241 are connected to different external pneumatic devices, and the first-route purified water distribution point-of-use system 3 and the second-route purified water distribution point-of-use system 4 control the opening and closing of the first point-of-use valve 231 and the second point-of-use valve 241 by controlling the external pneumatic devices.

[0029] In addition, the first purified water distribution point system 3 and the second purified water distribution point system 4 are connected to a control module 5 , and the control module 5 is connected to the pure steam generator 1 .

[0030] Furthermore, the first purified water distribution point system 3 or the second purified water distribution point system 4 receives the water demand signal from the pure steam generator 1 to control the opening and closing of the first point valve 231 or the second point valve 241, and the pure steam generator 1 controls the first point valve 231 or the second point valve 241 to switch regularly.

[0031] When starting up, the first purified water distribution point system 3 or the second purified water distribution point system 4 sends a point availability signal to the pure steam generator 1, and the pure steam generator 1 pre-sets a certain system for pure water supply and automatically switches the supply as needed.

[0032] Specifically, the volume of the pure steam generator 1 is 1000-1200L, and the pure steam generation speed of the pure steam generator 1 is 3.3-3.6m 3 / H.

When the pure steam generator 1 is turned on and running, it will send a water demand signal to one of the purified water distribution point systems. The purified water distribution point system that receives the water demand signal controls the corresponding first point valve 231 or the second point valve 241 to open for water supply.
