Description

A direct drinking water supply pipe network system

technical field

The utility model relates to the technical field of water supply pipe network, in particular to a direct drinking water supply pipe network system.

Background technique

With the improvement of our people's living standards, people's requirements for drinking water are getting higher and higher.

The deteriorating water environment has led to the inability of conventional water treatment to completely remove harmful components in water, seriously affecting people's health. The "Drinking Water Hygienic Standard" (GB5749-85) implemented by the tap water industry has few testing items, and there is still a certain gap in some indicators compared with developed countries, so it cannot be directly drunk. There are quite serious secondary pollution problems in the tap water pipe network system, such as pipe corrosion, leakage, scaling, sedimentation, and roof water tanks that are not cleaned and disinfected frequently. Purified water, distilled water, etc. remove harmful components in the production process and at the same time remove essential trace elements that are beneficial to the human body, so too pure water is not good for human health. There are secondary pollution problems in the use of bottled water, such as the pollution of the water dispenser itself, the pollution caused by insects entering the water outlet, and the air directly entering the bucket. Direct drinking water, also known as healthy running water, refers to water that is free from pollution, meets the physiological needs of the human body (contains beneficial mineral elements similar to the human body), and has a pH value that is weakly alkaline. Direct drinking water can solve the problem. The above problems, so the scope of application is more and more extensive. The existing direct drinking water supply pipe network system generally adopts the way of supplying upwards. Buildings close to the water supply point have a short backflow process and a fast cycle. Buildings far from the water supply point have a long backflow process and a slow cycle, resulting in The water quality is uneven, and the same journey backflow is not realized. In addition, the water supply at the water point needs to be branched from the main water supply pipe, and a control node regulating valve is installed separately. The branch pipe water supply behind the control node regulating valve cannot return to the equipment room, which is called Dead water area, the dead water area of the existing direct drinking water supply pipe network system is too long, which affects the quality of direct drinking water obtained by users.
