Because color waterpipe exit is sealed in main pipeline, to its maintenance and particularly trouble of replacing.
Utility model content
The utility model provides a kind of Reynolds experiment device, and object is to avoid pigment water pipe to stop up.
To achieve these goals, the technical scheme that the utility model is taked is: Reynolds experiment device, comprisesMain water box, color water tank, exhausted bath box, be arranged at water pump in main water box, be connected with water pump and for leadingWater in water tank is delivered to the water main of exhausted bath box and for connecting the color water of color water tank and water mainPipe, also comprises being connected with described water main and described color water pipe and for allowing the water in main water box can flow to faceCleaning hose in look water pipe, water main is provided with flowmeter.
The tie point of described cleaning hose and described water main is positioned at the company of water pump and described color water pipe and water mainBetween contact, the tie point of cleaning hose and color water pipe is positioned at described color water tank and color water pipe and water mainTie point between.
Described color water pipe is provided with a valve, and this valve be positioned at described color water tank and described cleaning hose itBetween.
Described water main is provided with a valve, and this valve is between described cleaning hose and described color water pipe.
Described color water pipe is connected with described water main by articulation.
Reynolds experiment device of the present utility model, the cleaning hose being connected with water main by being arranged at color water pipe,Can make water in water main flow in color water pipe color water pipe is cleaned, prevent that each experiment from finishingAfter due to the delay of pigment water and the residual pigment deposition causing, avoided pigment water pipe to go out stream smooth or stop upThe appearance of situation, the recycling rate of waterused and the life-span that are conducive to improve Reynolds experiment device.
Brief description of the drawings
This description comprises the following drawings, shown in content respectively:
Fig. 1 is the structural representation of the utility model Reynolds experiment device;
In figure, be labeled as:
1, main water box; 2, return duct; 3, water pump; 4, cleaning hose; 5, color water tank; 6, color waterPipe; 7, articulation; 8, water main; 9, flowmeter; 10, exhausted bath box; 11, blow-down pipe.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, to detailed description of the invention of the present utility model do intoThe explanation that one step is detailed, object is to help those skilled in the art to design of the present utility model, technical sideCase has more complete, accurate and deep understanding, and contributes to its enforcement.
As shown in Figure 1, the utility model provides a kind of Reynolds experiment device, and it comprises main water box 1, refluxesPipe 2, color water tank 5, exhausted bath box 10, blow-down pipe, be arranged at water pump 3 in main water box 1, with water pump 3Connect and for the water in main water box 1 being delivered to the water main 8 of exhausted bath box 10 and for connecting color waterThe color water pipe 6 of case 5 and water main 8, also comprises being connected with water main 8 and color water pipe 6 and for allowing masterWater in water tank 1 can flow to the cleaning hose 4 in color water pipe 6, so just can make the current in water main 8To color water pipe 6, color water pipe 6 is cleaned, prevent each experiment finish after stagnant due to pigment waterStay and the residual pigment deposition causing the appearance of having avoided pigment water pipe to go out to flow smooth or stopping state.
Specifically, as shown in Figure 1, cleaning hose 4 is positioned at water pump 3 and color with the tie point of water main 8Between the tie point of water pipe 6 and water main 8, cleaning hose 4 is positioned at color water with the tie point of color water pipe 6Between case 5 and color water pipe 6 and the tie point of water main 8. Water main 8 one end are connected with water pump 3, anotherOne end is as the delivery port of draining in exhausted bath box 10. Color water pipe 6 one end are connected with color water tank 5, anotherPosition between the two ends of water main 8, one end is connected with water main 8, by the color water in color water tank 5Be delivered in water main 8. One end of cleaning hose 4 is connected with water main 8, and the other end and color water pipe 6 connectConnect, in the time that water pump 3 turns round, the water that enters water main 8 flow in color water pipe 6 through cleaning hose 4, at streamReturn in water main 8.
As shown in Figure 1, color water pipe 6 is provided with a valve d, and this valve d be positioned at color water tank 5 withBetween cleaning hose 4, valve d is used for controlling color water pipe 6 current break-makes. Color water pipe 6 is being carried outWhen cleaning, valve d need be closed, color water can not flowed in color water pipe 6.
As shown in Figure 1, water main 8 is provided with a valve c, and this valve c is positioned at cleaning hose 4 and colorBetween water pipe 6, in the time that color water pipe 6 is cleaned, valve c need be closed, make in water main 8Current direction cleaning hose 4, then enters in color water pipe 6, and color water pipe 6 is cleaned, and finally flows back to masterWater pipe 8.
As shown in Figure 1, as preferably, the water side of color water pipe 6 is by articulation 7 and water main 8Form removable connection, opening articulation 7 can repair or replace pigment water delivery port easily,The problem that cannot keep in repair and change in the situation of having avoided pigment water delivery port to damage, is conducive to improve Reynolds realThe recycling rate of waterused of experiment device and life-span.
As shown in Figure 1, on water main 8, be also provided with flowmeter 9 and valve e, flowmeter 9 be positioned at valve e withBetween color water pipe 6, valve e is between flowmeter 9 and the delivery port of water main 8. On cleaning hose 4Return duct 2 is provided with a valve a for controlling the valve b of the interior current break-make of cleaning hose 4 to be provided with one,When experiment is carried out, start water pump 3, valve-off b, opens valve a, c, d, e, control valve a, c,E, the interior water flow of adjustable main water pipe 8, changes flow-shape in main pipeline, and control valve d, can changePigment discharge. Flowmeter 9 can make traffic visualization in main pipeline simultaneously.
When experiment finishes, open valve a, b, e, valve-off d, c, can carry out color water pipe 6Clean, control valve a, b can optionally regulate washing water quantity simultaneously. Prevent each experiment finish after due toThe delay of pigment water and the residual pigment deposition causing, avoided pigment water pipe to go out stream not smooth or stopping stateOccur.
