Description

Technical Field

[0001] The utility model relates to the field of ultrapure water machines, in particular to an ultrapure water machine with controllable water intake and its alarm device. Background Technique

[0002] An ultrapure water machine is a water treatment device that uses methods such as pretreatment, reverse osmosis technology, ultra-purification treatment, and post-treatment to almost completely remove conductive media in water, and also removes colloidal substances, gases, and organic substances that do not dissociate in water to a very low level. The resistivity of the ultrapure water produced by an ultrapure water machine should generally be greater than 10 megohms, and water above 10 megohms is called ultrapure water. The high-quality ultrapure water outlet should exceed 18.25 megohms.

[0003] When the existing ultrapure water machine is in use, on the one hand, it needs to be connected to a water storage tank through a pipeline, and a manual switch is used to receive water at the water outlet. When the amount of water received is large, people are prone to forget to close the water outlet valve, resulting in excessive water output and overflow. On the other hand, when the filter element of the ultrapure water machine exceeds the use load, the resistance decreases, and the direct consequence is an increase in conductivity, which affects experiments and subsequent experimental measurements, and there is no alarm water stop device, which is not convenient for staff to handle and maintain in a timely manner.
