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
One: technical field
The present invention relates to a kind of pressure-superposed water supplying facility that in supply and drain water system, uses, particularly a kind of tap water pressure-superposed water supplying facility.
Two: background technology
Pressure-superposed water supplying facility in the prior art generally is divided into pot type and box two kinds of frame modes, and the ability of pot type pressure-superposed water supplying facility deposit water is little, though box pressure-superposed water supplying facility amount of the reserve water can accomplish very big its energy-conservation a little less than a bit.
Three: summary of the invention
The objective of the invention is to: design the pressure-superposed water supplying facility that a kind of case jar share, its deposit outlet capacity is strengthened, its energy saving of equipment, reliability improve, and reduce equipment investment simultaneously.
The present invention adopts following structure to realize above-mentioned purpose; A kind of pressure-superposed water supplying facility by: current stabilization jar, water tank, laminate pump, booster pump, motor operated valve, valve member, tube connector, control instrument and switch board and form, current stabilization jar and water tank adopt and are connected in parallel, and motor operated valve is installed on the delivery port of current stabilization jar; Booster pump with laminate pump and adopt and to be connected in series; Booster pump water inlet is connected to water tank, and water outlet is connected in parallel to the water outlet of current stabilization jar and laminates the pump water inlet mouth and gather pipe, laminates to pump water and be connected to outfall sewer.
Adopt as above structure; During the equipment operate as normal tap water through the current stabilization jar after laminate the pump supercharging that on the tap water pressure basis, superposes and supply with the user and use; Reach purpose of energy saving; When the tap water pressure flow can not satisfy instructions for use, current stabilization jar delivery port place motor operated valve turned down gradually, guaranteed that through the tap water flow of controlling through the current stabilization jar tap water pressure is stable; At this moment booster pump turns round automatically the water in the water tank is carried out satisfying the traffic demand that laminates pump after the supercharging, guarantees that with this system water supply is stable.
Four: description of drawings
Fig. 1 implements state diagram for the present invention
Five: the specific embodiment
A kind of pressure-superposed water supplying facility as shown in Figure 1 comprises: current stabilization jar 1, and water tank 2 laminates pump 3; Booster pump 4, motor operated valve 5, one way valve 14, control instrument, tube connector, valve and switch board compositions such as (not marking among the figure), control instrument is made up of pressure sensor 6, pressure meter 7 and liquid level controller 8, and liquid level controller 8 does not have water conservation for water tank; The tap water water inlet is connected with water tank 2 with current stabilization jar 1 respectively through tube connector 9, and valve and pressure sensor are installed on tube connector 9, at the inlet water tank place float valve 10 is installed; Tap water can flow to current stabilization jar 1 and water tank 2 simultaneously; Float valve 10 is in closed condition during water tank 2 full waters, the outlet of current stabilization jar 1 through motor operated valve 5 back with gather pipe 11 and be connected, the water inlet of booster pump 4 is passed through to be connected with water tank 2 behind the valve; Water outlet through valve sets after with gather pipe and 11 be connected; Simultaneously water tank 2 also through tube connector 15 and one way valve 14 with gather pipe 11 and be connected, the water inlet that laminates pump 3 is managed 11 and is connected with gathering through valve sets, exports to pass through after the valve sets with outfall sewer 12 connections; Outfall sewer 12 is provided with the mouth of pipe 13 that connects the user; Be the low discharge low-lift pump in order to save equipment investment booster pump 4, tap water is supplied with user's use through current stabilization jar 1 after laminate pump 3 supercharging that on the tap water pressure basis, superpose when the equipment operate as normal, reaches purpose of energy saving.When the tap water pressure flow can not satisfy instructions for use; Automatically controlling current stabilization jar 1 delivery port place motor operated valve 5 when switch board (marking among the figure) detects tap water intake pressure deficiency through pressure sensor turns down gradually; Control guarantees that through the tap water flow of current stabilization jar 1 tap water pressure is stable; At this moment booster pump 4 turns round automatically the water in the water tank 2 is carried out satisfying the traffic demand that laminates pump 3 after the supercharging, and it is stable to guarantee that with this custom system supplies water.When tap water pressure continuation reduction system can not superpose supercharging on the tap water pressure basis; Control motor operated valve 5 Close Alls; Booster pump 4 because of flow less than flow system flow at this moment booster pump 4 close automatically; Since water tank 2 also through tube connector 15 and one way valve 14 with gather pipe 11 and be connected, laminate pump 3 and guarantee the constant employing raising frequency operation of outlet pressure (operating frequency rises to 60HZ by specified 50HZ and improves pump rotary speed and promote exit of pump pressure) pattern work because of inlet pressure disappears, the assurance system pressure is stablized and is steady; The lifting means operational reliability, system gets back to former stack boost mode automatically after tap water pressure recovers.
