Water compensation type supercharged box-type non-negative pressure water supply device

Abstract

The invention discloses a water compensation type supercharged box-type non-negative pressure water supply device, and relates to the technical field of municipal water supply. The water compensationtype supercharged box-type non-negative pressure water supply device includes a municipal water inlet manifold and a water outlet manifold, the water inlet end of the municipal water inlet manifold issequentially connected with a water inlet main valve, a Y-type filter, and a backflow preventer, the municipal water inlet manifold is divided into two paths, one path of the municipal water inlet manifold is sequentially connected to a solenoid ball cock, a water tank, the other path of the municipal water inlet manifold is connected to a municipal switching valve and is divided into three branches after passing through a section of a municipal water inlet manifold straight pipe. According to the supercharged box-type non-negative pressure water supply device, the method of canceling and replacing a small pump with a standby main pump for water compensation is adopted, the compensation capacity and compensation stability of a system are improved, and thus the device is more cost-effective, more energy-saving, more reliable, and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of municipal water supply, in particular to a water outlet compensation pressurized box-type non-negative pressure water supply equipment. Background technique [0002] The traditional primary water supply can no longer meet the water demand of modern cities. In the early days, high-rise buildings were supplied with secondary pressurized water by air pressure, frequency conversion and other methods to change the status quo of urban water supply. This traditional secondary water supply method is not conducive to energy saving and easily causes secondary water supply due to the formation of many intermediate components such as pools and water tanks. secondary pollution. Later, the non-negative pressure water supply equipment was born because of its good land saving, energy saving, and pollution-free performance, and it is widely used in the water supply system of modern high-rise buildings. [0003] However,...
