Portion is provided with water inlet pipe 16；
The delivery port of described outlet pipe 15 connects the water inlet of high-lift pump 2, and the delivery port of high-lift pump 2 passes through
Threeway 3 connects the water inlet of isocon 4 and the water inlet of choke valve 5 respectively, and the delivery port of isocon 4 connects entering for water inlet pipe 16
The mouth of a river, the delivery port of choke valve 5 connects the water inlet of control valve 1, the delivery port of control valve 1 by feed pipe 1
One end of feed pipe 28 is connected, one end of the other end joint test pipeline 9 of feed pipe 28, the other end of test pipe 9 leads to
The water inlet that valve 2 10 connects return pipe 11 is overregulated, the delivery port of return pipe 11 is arranged on the top of casing 1.
The spout hole 17 of trapezoidal cylinder shape is uniformly distributed in the middle of orifice plate 13, the right-hand member eye diameter of spout hole 17 is left end hole
/ 2nd of eye diameter.
Flowmeter 6 is provided with described feed pipe 1.
Described experimental channel 9 is provided at both ends with pressure tap.
The beneficial effects of the utility model：
1st, the middle unstability for setting abacus 13, substantially reducing liquid level flowing of casing 1, is solved under indoor conditions
The instability problem of water pump direct-furnish.
2nd, threeway 3 reaches the throughput rate in the purpose of shunting, reduction laminar flow, isocon is returned to the right case of overflow
12, laminar flow and turbulent experiment can be preferably completed on same covering device.
