Description

Bubble water outlet valve

In order to ensure the taste of the bubble water, the amount of bubbles in the water to be discharged is not less than 2600ppb. The existing bubble water machine generally adopts a common water outlet valve to discharge water, and when bubble water in a pressure tank is discharged through the water outlet valve, the discharged bubble water has less bubble amount (about 2300 ppb) due to rapid pressure relief, so that the problem of poor taste is solved.

In order to solve the problems, a water outlet valve is also arranged on the market, and a small hole is formed in a water outlet channel, so that the precipitation of bubbles in the bubble water can be reduced to a certain extent, and the taste of the bubble water is ensured. However, in the above-mentioned mode, when the bubble water is discharged, the liquid pressure difference before and after flowing through the small hole is large, so that the flow rate of the discharged water is too large, and when the water is received, the bubble water can splash, so that the user experience is poor.
