Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and can feed water fast or regulate the feedwater quick response device of confluent and pressure.
The purpose of this utility model is to realize like this, comprise pond, water pump, main feed water pipe, described pond connects water inlet pipe, described water inlet pipe connects water pump, described water pump connects outlet pipe, and described outlet pipe connects main feed water pipe, on described main feed water pipe pipeline, circulating water pipe is set, the circulating water pipe other end is inserted in pond, on described circulating water pipe, hydraulic control valve is set.
The utility model by arranging circulating water pipe and hydraulic control valve on main feed line, in the time that the total water supply volume of user die-offs, pressure before hydraulic control valve will raise fast, and in the time reaching setting pressure as 1.5MPa, hydraulic control valve will be opened automatically, water returns to pond through circulating water pipe, the Pressure Drop of delivery side of pump end is got off, and when Pressure Drop is to below setting pressure time, hydraulic control valve is closed automatically, keep main feed line to have enough pressure of supply waters, thereby realize the function automatically regulating.The utility model has effectively guaranteed that user's point is in the short period of time to feedwater flow and pressure controlled demand.Effectively guarantee that user puts the characteristic of discontinuous water supply, also avoided in water supply process, shutting down suddenly because of water pump the situation that causes the course of work to interrupt simultaneously.Having stopped ductwork pressure exceeds standard and damages the phenomenon of conduit fittings, electrostatic precipitator venting of dust explosion.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
In figure: 1-pond, 2-unit fixed on water pump suction hand-operated valve, 3-water pump, 4-exit of pump flap valve, 5-exit of pump hand-operated valve, 6-main feed water pipe, 7-circulating water pipe, 8-hydraulic control valve, 9-water control valve, 10-water outlet mouthpiece, 11-pressure relief opening.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, based on any change of the present utility model or improvement, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises pond 1, water pump 3, main feed water pipe 6, described pond 1 connects water inlet pipe, described water inlet pipe connects water pump 3, described water pump 3 connects outlet pipe, and described outlet pipe connects main feed water pipe 6, on described main feed water pipe 6 pipelines, circulating water pipe 7 is set, circulating water pipe 7 other ends are inserted in pond 1, on described circulating water pipe 7, hydraulic control valve 8 are set.
The caliber of described circulating water pipe 7 is calculated as follows:
, wherein: F=Qmin/ V, Qmin is minimum continous-stable flow, V is the flow velocity of circulating line section, determines according to the minimum continous-stable flow value of water pump.
On described circulating water pipe 7, pressure relief opening 11 is set.
Unit fixed on water pump suction hand-operated valve 2 is set on described water inlet pipe.
Exit of pump flap valve 4 and/or exit of pump hand-operated valve 5 are set on described outlet pipe.
On described main feed water pipe 6, water outlet mouthpiece 10 is set.
Described water outlet mouthpiece 10 arranges in groups, to meet different water needs.
Described water outlet mouthpiece 10 front portions arrange respectively with water control valve 9.
Below take 120t converter evaporative cooling feed-water pump as example further illustrates operating principle of the present utility model and the course of work:
The utility model by arranging circulating water pipe and hydraulic control valve on main feed line, in the time that the total water supply volume of user die-offs, pressure before hydraulic control valve will raise fast, and in the time reaching setting pressure as 1.5MPa, hydraulic control valve will be opened automatically, water returns to pond through circulating water pipe, the Pressure Drop of delivery side of pump end is got off, and when Pressure Drop is to below setting pressure time, hydraulic control valve is closed automatically, keep main feed line to have enough pressure of supply waters, thereby realize the function automatically regulating.
Data according to 120t converter evaporative cooling feed pump: lift 154m, flow 30m
3the minimum continous-stable flow Q that/h, producer provide
min=15 m
3/ h, main feed water pipe is DN150, by looking into " water supply and drainage design manual ", obtains the flow velocity V=3.5m/s of circulating water pipe duct section, circulating water pipe duct section discharge area: F=Q
min/ V=0.0012m
