Accompanying drawing explanation
Figure 1 shows that the structural representation of the non-negative pressure water-supply installation test platform that the utility model one embodiment provides.
Detailed description of the invention
As shown in Figure 1, the non-negative pressure water-supply installation test platform that the present embodiment provides comprises water feed apparatus 100, experimental rig 200 and water recovery apparatus 300.Water feed apparatus 100 comprises water tank 110, connects the water pump 120 of water tank 110, connects the first motor operated valve 130 of water pump 120, connects the first steady-flow tank 140 of the first motor operated valve 130.Experimental rig 200 has water inlet end 201 and water side 202.Water inlet end 201 is connected with water feed apparatus 100, and experimental rig 200 comprises at least one non-negative pressure water-supply installation 210.The water side 202 of water recovery apparatus 300 joint test device 200.Water recovery apparatus 300 comprise connect water side 202 the second steady-flow tank 310, connect the second motor operated valve 320 of the second steady-flow tank 310, connect the flow meter 330 of the second motor operated valve 320, and the 3rd steady-flow tank 340 of connection traffic meter 330, and the delivery port of the 3rd steady-flow tank 340 is connected with water tank 110.
The water supply situation of the effective simulation city planting ductwork of water feed apparatus 100, the actual used water situation of water recovery apparatus 300 then analog subscriber.Water feed apparatus 100 and water recovery apparatus 300 effectively simulate the real work situation of non-negative pressure water-supply installation, thus the complete detection realized experimental rig 200, greatly improve the outgoing of non-negative pressure water-supply installation, supply water and working stability when ensureing that non-negative pressure water-supply installation uses at the scene.
In the present embodiment, experimental rig 200 comprises four non-negative pressure water-supply installations 210, is respectively box type negative-pressure-free supply equipment, direct-connected pressurization supply equipment, frequency conversion pressurization supply equipment and pot type non-negative pressure water-supply installation.But the utility model is not limited in any way this.In other embodiment, user can according to actual needs, the one or more combination in above-mentioned four non-negative pressure water-supply installations 210 of choose reasonable.
In the non-negative pressure water-supply installation test platform that the utility model provides, all devices (as the first motor operated valve 130, second motor operated valve 320 etc.) in water feed apparatus 100, experimental rig 200 and water recovery apparatus 300 and the voltage withstand class of connector (as all pipelines, flange etc.) are all higher than the most high test pressures of experimental rig 200.This regulation ensures non-negative pressure water-supply installation test platform safe and stable operation in whole process of the test.
For better simulating pressure and the fluctuation situation of city planting ductwork water supply, attached with frequency converters on water pump 120.Further, water pump 120 is set for large discharge, low lift type water pump.In the present embodiment, be better analog subscriber regimen condition, the second motor operated valve 320 is set and flow meter 330 all has multiple caliber.Select different calibers according to flow, can avoid because flow velocity is too fast and cause result of the test to occur deviation.
In the present embodiment, the water inlet pipe of connection water tank 110, water pump 120, first motor operated valve 130 and the first steady-flow tank 140 adds steel pressure meter 150, and user can control the flow in water inlet pipe by steel pressure meter 150.And be the monitoring precision improving pressure further, the pressure sensor 160 be connected with steel pressure meter 150 is also provided with in the side of steel pressure meter 150.
In the present embodiment, the top of the first steady-flow tank 140, second steady-flow tank 310 and the 3rd steady-flow tank 340 is provided with vacuum suppresser.By increasing vacuum suppresser, when each equipment debugging, carry out emptying without the need to manually driving atmospheric valve.Meanwhile, vacuum suppresser also can ensure that non-negative pressure water-supply installation can not produce negative pressure in whole debug process, can not have any impact to equipment.Further, for ease of cleaning, the bottom of the first steady-flow tank 140, second steady-flow tank 310 and the 3rd steady-flow tank 340 is provided with sewage draining valve.
