Building water supply system corrosion and scale prevention device and control method thereof

Abstract

The invention discloses a building water supply system corrosion and scale prevention device and a control method thereof. The building water supply system corrosion and scale prevention device is arranged on a water supply pipeline between a water meter of a conventional building family splitting water supply system and a domestic water faucet and comprises an air diaphragm tank, a closed air pressure tank, a control unit and multiple valves arranged on the water supply pipeline; the water supply pipeline comprises a main pipeline arranged behind the water meter, a first pipeline enabling themain pipeline to be connected with the closed air pressure tank, a second pipeline enabling the main pipeline to be connected with the air diaphragm tank and a third pipeline enabling the closed airpressure tank to be connected with the air diaphragm tank; and the closed air pressure tank is connected with the domestic water faucet. The control method of the building water supply system corrosion and scale prevention device comprises the steps that the water feeding work condition is set at the system running time from 6 a.m. to 10 p.m., and the circulating work condition is set at the system running time from 10 p.m. to 6 a.m. on the next day. According to the building water supply system corrosion and scale prevention device and the control method thereof, arrangement is easy, controlis reliable, the available pressure of a water supply network is fully utilized, and circulation of fed water between the water supply pipeline and a circulating pipeline is promoted.

Description

【Technical field】 [0001] The invention belongs to the technical field of building water supply, and specifically refers to a building water supply system anti-corrosion and anti-scaling device and a control method thereof. 【Background technique】 [0002] Building household water supply system is a relatively common water supply method at present. The water supply company supplies water to the bottom of the building, and after being measured by centralized water meters, it is supplied to each user by household. The water supply pipes of domestic buildings mostly use iron pipes or PVC pipes. For now, for some houses over five years old, most of the water pipes are iron pipes. After a long time of use, the walls of the water pipes will begin to deposit heavy metals, breed bacteria, and microalgae Harmful substances such as plants gradually begin to corrode the inner and outer walls of the water pipes, causing water rust. As the usage time increases, the corrosion and fouling w...
