The utility model provides a technical scheme that above-mentioned problem adopted is: the quick-assembly valve performance testing system is characterized by comprising a water tank, wherein the water tank is communicated with a water supply header through a water supply main pipe, the water supply main pipe is connected with a variable frequency pump and a main pipe valve, the water supply header is communicated with a water return header through a testing branch and a contrast branch, the testing branch and the contrast branch are arranged in parallel, the testing branch is provided with a plurality of pieces in parallel, the testing branch is connected with a first manual valve, a testing valve, a second manual valve and a float flowmeter, the contrast branch is connected with a first manual valve and a float flowmeter, pressure meters are installed on the water supply main pipe, the water return main pipe and the testing branch, one end of the water return main pipe is connected to the water tank, and a temporary plug is installed at the other end of the water return main pipe.

Furthermore, 3 test branches are arranged in parallel.

Furthermore, on the test branch, the pressure gauge is respectively arranged between the first manual valve and the test valve and between the test valve and the second manual valve.

Compared with the prior art, the utility model, have following advantage and effect:

the utility model has the advantages of reasonable design, equipment selection safe and reliable can on-spot fast assembly shaping. The extension of the female pipe homoenergetic extension of water supply and return water can test a plurality of valves simultaneously according to actual need. The pressure gauge installed in the system can test the pressure loss index of the valve under different flow conditions, the float flow meters arranged in each branch can visually read the flow, and the added control branch can visually reflect the flow characteristic of the valve.

The utility model discloses equipment purchase is convenient, but on-the-spot fast assembly, and specially adapted minor caliber, unconventional valve characteristic curve detect usefulness on the spot, have higher practical value.
