Negative-pressure resistance water supply device for high-rise building and use method of negative-pressure resistance water supply device

Abstract

The invention discloses a negative-pressure resistance water supply device for a high-rise building and a use method of the negative-pressure resistance water supply device. The negative-pressure resistance water supply device comprises a first water press chamber, a second water press chamber, a negative-pressure resistance box, a water pump unit and a control box. The negative-pressure resistance box communicates with a municipal pipe network, a water pressure gauge and a first electromagnetic valve are arranged at the tail end of the municipal pipe network, a water level detector is arranged in the negative-pressure resistance box, the negative-pressure resistance box communicates with the water pump unit through a pipeline, the water pump unit communicates with the first water press chamber and the second water press chamber through water inlet pipes, and the water inlet pipes are provided with a second electromagnetic valve and a third electromagnetic valve. The bottom of the first water press chamber and the bottom of the second water press chamber communicate with drain pipes, the drain pipes are provided with a fourth electromagnetic valve and a fifth electromagnetic valve,and the drain pipes communicate with a high-rise user pipe network. A first air pressure control gauge and a second air pressure control gauge are arranged at the tops of the first water press chamber and the second water press chamber. The negative-pressure resistance water supply device can effectively solve the problems of easy pollution in a water tank of an existing water supply device, thefailure of water supply when the municipal pipe network is abnormal, and continuous operation of water pumps easily causes negative pressure in the municipal pipe network.

Description

technical field [0001] The invention belongs to the technical field of high-rise water supply devices, and in particular relates to a high-rise building anti-negative pressure water supply device and a use method thereof. 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 and pressurizes it, and sends it to the user pipeline for use by residents of high-rise buildings. The supporting control circuit functions, and works in 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 h...
