Abstract
The invention discloses it is a kind of can the drainage system experimental rig that adjusts of multistage flow, including pond, immersible pump, the first valve, the second valve, wide range spinner flowmeter, third valve, small-range spinner flowmeter, immersible pump is placed in pond, the outlet of immersible pump is connected with the entrance of the first valve, the second valve and third valve respectively, the outlet of first valve is connected with pond, the outlet of second valve is connected with the entrance of wide range spinner flowmeter, and the outlet of third valve is connected with the entrance of small-range spinner flowmeter.The control and adjusting of multistage flow drainage can be realized using a set of pipe-line system.When multistage flow switches, control valve is only needed, without dismantling and reinstalling, switching is easy.Provided with water return pipeline, occurs pipeline junction when avoiding minimum flow and burst problem because pressure is excessive.
Description
Technical field
The present invention relates in a kind of river model drainage system experimental rig more particularly to a kind of multistage flow adjust
Drainage system experimental rig.
Background technique
In river model test, accurately control and the adjusting of discharge outlet flow are research drainings to surrounding body environment shadow
Relatively crucial problem is rung, at present for the discharge outlet of flow control, common method is water pump-pipeline-valve-flowmeter-
The discharge outlet experimental rig of the part such as outlet pipe composition, but because of the limitation of flowmeter range, traffic level span is compared
Big situation then needs to assemble the drainage test device of more set different flow ranks, is needed during the test according to traffic level
Demand carries out the repeated works such as disassembly replacement installation between the drainage arrangement of different flow rank, expends the regular hour, together
When expend certain economic cost again.For this purpose, need to construct it is a kind of can multistage flow control drainage test device.
Summary of the invention
For the defect of existing drainage test device, the present invention provides a kind of drainage test dresses of multistage flow control
It sets, is that one kind is at low cost, traffic level is easy to the drainage arrangement solution switched.For drainage arrangement in river model test
Multi-level flow adjust and control.
The technical solution adopted in the present invention is as follows：It is a kind of can the drainage system experimental rig that adjusts of multistage flow, including
Pond, immersible pump, the first valve, the second valve, wide range spinner flowmeter, third valve, small-range spinner flowmeter, diving
Pump is placed in pond, and the outlet of immersible pump is connected with the entrance of the first valve, the second valve and third valve respectively, and first
The outlet of valve is connected with pond, and the outlet of the second valve is connected with the entrance of wide range spinner flowmeter, third valve
Outlet be connected with the entrance of small-range spinner flowmeter.
Further, the range of flow of the wide range spinner flowmeter be 10~50 cubic metres per hour, small-range turn
The range of flow of subflow meter be 1~10 cubic metre per hour.
Further, the immersible pump is placed in the bottom in pond.
Further, first valve, the second valve and third valve are ball valve.
Further, the maximum pump-out of the immersible pump should be not less than 1.5 of maximum drain discharge needed for river model
Times.
Beneficial effects of the present invention are as follows：
1. can realize the control and adjusting of multistage flow drainage using a set of pipe-line system.
2. only needing control valve when multistage flow switching, without dismantling and reinstalling, switching is easy.
3. being provided with water return pipeline, occurs pipeline junction when avoiding minimum flow and burst problem because pressure is excessive.

Wherein the maximum pump-out of immersible pump 2 should be not less than 1.5 times of maximum drain discharge needed for river model, immersible pump
It is placed in the bottom in pond 1.Connecting tube 3 is made of PVC hose, and the outlet of immersible pump 2 is used with one end of the first connecting tube 3 to block
One end of hoop connection, the other end of connecting tube 3, one end of return pipe 5 and the second connecting tube 11 passes through the first three-way connection phase
Connection, return pipe 5 also use PVC hose material, and the water outlet of return pipe 5 is placed in pond, and the first valve is installed on return pipe 5
4, return pipe 5 and the first valve 4 use clamp connection；The entrance and third of the other end of second connecting tube 11, the second valve 6
The entrance of valve 8 is connected by the second three-way connection, and wide range spinner flowmeter 7, third valve 8 are installed after the second valve 6
Small-range spinner flowmeter 9 is installed afterwards, third three-way connection is installed after flowmeter, two pipes are combined into a pipe, line end position
In 10 position of water outlet；Wherein, the first valve 4, the second valve 6 and third valve 8 are all made of ball valve.
When draining needs big flow, immersible pump 2 is opened, the first valve 4 is closed, the not return water of return pipe 5, third valve 8
It closes, the only water of small-range spinner flowmeter 9, by manually adjusting 6 aperture of the second valve, adjusts the finger of Mass Flow Meter 7
Needle is shown as specified flow.
When draining needs small flow, 4 standard-sized sheet of the first valve, immersible pump 2 is discharged water flow part and returns to water by return pipe 5
Pond 1 prevents siphon pressure excessive.Second valve 6 is closed, by manually adjusting third valve 8, adjustment small-range flowmeter 9
