Abstract
Water supply equipment without negative pressure comprises a steady-flow tank, a water tank, pressure superposition pumps, boosting pumps, an electric valve, a valve component, a connecting pipe, control instruments and a control cabinet; the steady-flow tank and the water tank are connected in parallel; the electric valve is mounted at the water outlet of the steady-flow tank; the pressure superposition pumps and the boosting pumps are connected in series; the water inlets of the boosting pumps are connected to the water tank, the water outlets and the water outlet of the steady-flow tank are connected with a gathering pipe of the water inlets of the pressure superposition pumps in parallel; the water outlets of the pressure superposition pumps are connected with a water outlet main pipe; the rated flow of the boosting pumps is greater than or equal to that of a water supply system, and the lift is equal to tap water normal pressure. When the equipment operates normally, the tap water is superposed and pressurized and then supplied for users based on the tap water pressure after passing though the steady-flow tank and then the boosting pumps, so that the purpose of energy conservation is achieved; when the tap water pressure cannot meet the use requirement of superposition, the control cabinet controls that the electric valve at the water outlet of the steady-flow tank gets smaller gradually, so as to ensure that the tap water pressure is stable and no negative pressure is caused; at the same time, the boosting pumps operate automatically, water in the water tank is pressurized, so that the requirements of the boosting pumps are met; therefore, the stable water supply of the system is guaranteed.
Description
One: technical field
The present invention relates to a kind of no-negative-pressure water supply equipment that in supply and drain water system, uses, particularly a kind of water source is the no-negative-pressure water supply equipment of tap water.
Two: background technology
No-negative-pressure water supply equipment in the prior art generally is divided into pot type and box two kinds of frame modes, and the ability of pot type no-negative-pressure water supply equipment deposit water is little, though box no-negative-pressure water supply equipment amount of the reserve water can accomplish that it is energy-conservation more weak very greatly.
Three: summary of the invention
The objective of the invention is to: design the no-negative-pressure water supply equipment that a kind of case jar share, make it both lay in outlet capacity and strengthen, its energy saving, reliability improve, and reduce equipment investment simultaneously.
The present invention adopts following structure to realize above-mentioned purpose; A kind of no-negative-pressure water supply equipment 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; The metered flow of booster pump is more than or equal to the water system flow, and lift equals the tap water normal pressure.
Adopt as above structure, tap water after laminate the pump supercharging that on the tap water pressure basis, superposes and supply with the user and use, reaches purpose of energy saving through the current stabilization jar during equipment operate as normal; When tap water pressure can not satisfy when laminating instructions for use; Switch board control current stabilization jar delivery port place motor operated valve turns down gradually, and the assurance tap water pressure is stable not to produce negative pressure, and at this moment booster pump turns round automatically; Water in the water tank is carried out satisfying the demand that laminates pump after the supercharging, guarantee 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 no-negative-pressure water supply equipment as shown in Figure 1 comprises: current stabilization jar 1, and water tank 2 laminates pump 3; Booster pump 4, motor operated valve 5, control instrument, tube connector, valve and switch board compositions such as (not marking among the figure), control instrument comprises pressure sensor 6, pressure meter 7 and liquid level controller 8, 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 like this; Float valve 10 is closed automatically 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; Booster pump 4 is the using and the reserved, the water inlet that laminates pump 3 through valve sets with gather pipe 11 and be connected, outlet through after the valve sets with outfall sewer 12 connections; Laminate pump 3 and can be 1 or many combinations; Outfall sewer 12 is provided with the mouth of pipe 13 that connects the user, and tap water is supplied with user's use through current stabilization jar 1 after laminate pump 4 supercharging that on the tap water pressure basis, superpose when the equipment operate as normal, reaches purpose of energy saving.Automatically control current stabilization jar 1 delivery port place motor operated valve 5 turns down gradually when switch board (marking among the figure) detects tap water intake pressure deficiency through pressure sensor; 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 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; Motor operated valve 5 Close Alls; Since booster pump 4 because of flow more than or equal to flow system flow, booster pump 4 full speed runnings at this moment, guarantee system pressure stable with steadily; The lifting means operational reliability is got back to former stack boost mode automatically when tap water pressure recovers after booster pump 4 system that shuts down automatically.
