Turn handle: feels light spool
Common faucet spools have steel ball spools and ceramic spools. Plieninio rutulinio vožtuvo šerdis turi gerą atsparumą slėgiui, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. Palyginti su plienine rutulinio vožtuvo šerdimi, the ceramic valve core is more resistant to heat and wear, and the ceramic valve core itself has a good sealing performance, so that a high degree of opening resistance can be achieved, and the nozzle is not dripped due to the wear of the valve core. Maišytuvas su keramine vožtuvo šerdimi yra patogesnis ir lygesnis rankoje, ir jis greitai atidaromas ir uždaromas. Since the spool is inside the faucet, vartotojas pirkdamas nemato ritės, bet vartotojas gali tiesiog nuspręsti, ar ritė gera ar bloga, pagal pojūtį sukant rankeną. Paprastai, turning the handle up, žemyn, kairėje, Ir teisingai, if it feels light and has no blockage, it means the spool is better.
Look at the appearance: the coating should be bright as a mirror
After the faucet is ground and polished, the surface should be plated with nickel or chrome. The water faucet is oxidized. After the nickel or chromium plating, the faucet pass the Neutral salt spray. Po testo, danga turi būti be rūdžių. It is understood that only the faucet passed the neutral salt spray test can be shipped. Perkant, it is best to place the faucet in a place with sufficient light. The surface of the faucet should be bright as a mirror, be jokių oksiduotų dėmių, degimo žymės, Nėra porų, Nėra pūslių, nėra nuotėkio padengimo, vienodos spalvos; The hand touches no burrs and sand grains; after pressing the faucet with a finger, the fingerprint spreads quickly and is not easy to adhere to dirt.
To be tested: quality is more guaranteed
The main body of the faucet is generally brass. The quality of the products made of brass is guaranteed to be the best. Kuo didesnis žalvario grynumas, tuo geresnė dengimo kokybė, and the harder the surface plating layer is. In order to reduce costs, some manufacturers use zinc alloy instead of brass. Although the country allows the use of zinc alloy materials instead of brass, the zinc alloy plating quality is poor and the corrosion resistance is not strong. Apskritai, consumers can use the method of estimating weight when purchasing. Žalvaris yra sunkesnis ir kietesnis, and zinc alloy is lighter and softer. Experts caution that the quality of the faucet should not be judged by weight alone, because some manufacturers can make the faucet heavier by increasing the wall thickness of the faucet or adding other metal materials. Consumers should ask the salesperson for a test report for the product. Jei bandymo ataskaitoje nustatoma, kad gaminys yra kvalifikuotas, it can be purchased.
Test water flow: subject to foaming
Consumers should try to choose a faucet with a aerator when purchasing, ir pajuskite vandens tekėjimą rankos prisilietimu. Vandens srautas yra minkštas ir putojantis (the bubble content of the water flow) yra turtingas, rodo, kad aeratoriaus kokybė yra geresnė. The aerator generally consists of six layers, paprastai susideda iš metalinio tinklinio dangčio (iš dalies plastikinis). Kai vanduo teka per tinklinį dangtelį, jis supjaustomas į daugybę mažų vandens stulpelių, tarp kurių yra oro, so that the water is not torn apart.
Prekės ženklo pripažinimas: after-sales service is guaranteed
