Pressure-superposing water feeding device

Abstract

A pressure-superposing water feeding device is composed of a stabilizing tank, a water box, a pressure-superposing pump, a boosting pump, an electrically-operated valve, a valve assembly, a connection pipe, a control instrument and a control cabinet, wherein the stabilizing tank is parallelly connected with the water box, the electrically-operated valve is installed on a water outlet of the stabilizing tank, the boosting pump is serially connected with the pressure-superposing pump, a water inlet pipe of the boosting pump is connected with the water box, a water outlet pipe of the boosting pump and a water outlet pipe of the stabilizing tank are parallelly connected with a converging pipe at the water inlet of the pressure-superposing pump, and a water outlet pipe of the pressure-superposing pump is connected onto a water outlet main pipe. When the pressure-superposing water feeding device works normally, tap water is performed with pressure-superposing boosting on the pressure-superposing pump on the basis of the tap water pressure and supplied to users for use through the stabilizing tank, so that the aim of energy saving is achieved. When pressure flow of the tap water cannot meet the using requirement, the electrically-operated valve at the water outlet of the stabilizing tank is gradually turned down, the pressure of the tap water is controlled to be stable by controlling the flow of the tap water passing through the stabilizing tank, the boosting pump operates automatically to pressurize the water in the water tank so as to meet the requirement for flow of the pressure-superposing pump, and stabilization in water supplying of the system is ensured.

Description

1: Technical field [0001] The invention relates to a laminated water supply equipment used in a water supply and drainage system, in particular to a tap water laminated water supply equipment. Two: background technology [0002] The stacked water supply equipment in the prior art is generally divided into tank type and box type. The tank type stacked water supply equipment has a small water storage capacity, and the box type stacked water supply equipment can store a large amount of water. Energy saving is weaker. Three: Invention content [0003] The purpose of the present invention is to design a stacked water supply equipment for tanks and tanks, so as to enhance its water storage capacity, improve its energy saving performance and reliability, and reduce equipment investment at the same time. [0004] The present invention adopts the following structure to achieve the above object. A stacked water supply equipment is composed of a steady flow tank, a water tank, a sta...
