A constant-pressure secondary water supply device for high-rise buildings

Abstract

A constant-pressure secondary water supply device for high-rise buildings comprises a constant pressure secondary water supply system body. The upper part of the water tank of the main body of the constant pressure secondary water supply system is in a fully enclosed state, a switch power supply, Battery, solenoid inlet valve, a water supply circuit, a solenoid drain valve, a solenoid bypass valve, a pneumatic switch, a water level switch, a solenoid valve, and a pneumatic tank are installed on the ground, and the pneumatic tank is connected with the solenoid valve, a solenoid valve, a water level switch, a solenoid inlet valve, a solenoid drain valve, a pneumatic switch, and a solenoid bypass valve are installed on the water tank, and are connected with a switching power supply and a battery through a wire. As that upper part of the water tank is all in a closed state, external pollutants can be effectively prevent from entering the water tank, thereby leading to the pollution of water inside the water tank, and the normal water consumption of the user can be ensured within a period of time after the power failure of the mains AC power supply, and the influence of the power failure on the user water consumption can be minimized as much as possible. Based on the above, the present invention has a good prospect.

Description

technical field [0001] The invention relates to the field of secondary water supply equipment, in particular to a constant-pressure secondary water supply device for high-rise buildings. Background technique [0002] The constant-pressure secondary water supply system for high-rise buildings is a widely used secondary water supply equipment. During work, the under-pressure municipal pipe network tap water flows into the water tank for storage, and then the pressurization of the constant-pressure secondary water supply system is controlled by related equipment. The pump pumps water out of the water tank to pressurize it, and sends it to the user pipeline for use by residents of high-rise buildings. The control circuit works under the automatic state. When the water pressure on the user side is low, the booster pump works to pump water with pressure into the user pipeline. When the water pressure on the user side is high, the booster pump stops. In this way, the water in the u...

Problems solved by technology

[0005] In order to overcome the disadvantages of the existing constant pressure secondary water supply system that users cannot use water normally after a power outage, the present invention provides a pressure tank and a corresponding water supply circuit for use in combination with the existing constant pressure secondary water supply system. The upper part of the water tank of the main body of the secondary water supply system is in a closed state, which can effectively prevent external pollutants from entering the water tank, thereby causing water pollution inside the water tank. line power supply), the water supply circuit will automatically close the water inlet solenoid valve and the emptying solenoid valve on the upper end of the water tank, and can input suitable compressed air into the water tank according to the pressure detection data of the air pressure switch, and under the action of the relevant mechanism, there will be pressure The high water pressure enters the user's pipeline, so that within a period of time after the 220V mains power failure, it can also ensure the normal water consumption of the user and minimize the impact of the power failure on the user's water use.
