Description
technical field [0001] The invention belongs to the testing field, in particular to a water-saving performance testing instrument. Background technique [0002] The water-saving performance test device for building water supply system water appliances is an important experimental teaching and scientific research device for testing the water-saving performance of some appliances in the building water supply system under different working pressures. With the increasing shortage of urban water resources, water conservation has become an important part of my country's national policy of energy conservation and emission reduction. In urban water use, building water accounts for 40% to 60% of urban water consumption, so it is particularly necessary to do a good job in building water conservation. As an important part of the building water supply system and the water distribution terminal (reducing valve, filter, water meter, faucet, shower nozzle, etc.), the water appliance of th...
