Non negative pressure steady flow automatic water supply equipment

Abstract

The invention relates to no negative pressure steady flow auto water-supply installation. It includes influent back valve, steady head tank, pressure sensor, frequency conversion tank, control valve, feed pump, and liquid level sensor. Its feature is has a steady flow tank connected to tap water influent pipe; the steady flow tank is connected with vacuum breaker; its outlet is connected with at least two pump and control valve. One discharging tube is connected with three back valves; the back valve is respectively connected to pump outlet and control valve outlet; the discharging tube is connected with steady head tank and pressure sensor; the liquid level sensor, pressure sensor, and pump are connected with frequency conversion tank. The advantages of the invention are that it can prevent water pollution caused by secondary water-supply installation; and it also can reduce electric energy consumption.

Description

technical field [0001] The invention relates to an automatic water supply device, in particular to an automatic water supply device with no negative pressure and steady flow. Background technique [0002] At present, when the general water supply equipment is directly connected to the water pipe network, there will be negative effects, because the flow rate of the water pump is often greater than the water flow of the water pipe, which will cause a drop in the pressure of the pipe network and affect the water use of surrounding users. In order to solve the irrationality of this water supply scheme, the traditional water supply method needs to build a water source water tank and a roof water tank at the inlet of the water pump. There are three problems in this traditional water supply scheme. First, the water source water tank of the water pump and the roof water tank are both It is easy to have pollution problems, because there are overflow outlets in the design of the pools...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems existing in the traditional water supply and frequency conversion constant pressure water supply device in the prior art, and to provide a non-negative pressure device that can completely solve the problem of water quality pollution and energy waste caused by the secondary water supply equipment in the traditional water supply scheme. Stable flow automatic water supply equipment, while improving the reliability and automation of the original water supply scheme
