Turn handle: feels light spool
Common faucet spools have steel ball spools and ceramic spools. Jadro oceľového guľového ventilu má dobrý odpor voči tlaku, but the disadvantage is that the rubber sealing ring that acts as a seal is easy to wear and will soon age. V porovnaní s oceľovým guľovým ventilom jadrom, 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. Kohútik s keramickým jadrom ventilu je pohodlnejší a hladký v ruke, A je rýchle otváranie a zatvorenie. Since the spool is inside the faucet, spotrebiteľ nevidí cievku pri nákupe, Ale spotrebiteľ môže jednoducho posúdiť, či je cievka dobrá alebo zlá podľa pocitu pri otáčaní rukoväte. Všeobecne, turning the handle up, dole, vľavo, a správne, 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 teste, povlak by mal byť bez hrdze. It is understood that only the faucet passed the neutral salt spray test can be shipped. Pri nákupe, it is best to place the faucet in a place with sufficient light. The surface of the faucet should be bright as a mirror, bez oxidovaných škvŕn, spálené značky, Žiadne póry, Žiadne pľuzgiere, Žiadne pokovovanie úniku, rovnomerná farba; 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. The higher the purity of the brass, the better the plating quality, 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. Všeobecne, consumers can use the method of estimating weight when purchasing. Brass is heavier and harder, 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. Ak sa v správe o teste zistí, že produkt je kvalifikovaný, it can be purchased.
Test water flow: subject to foaming
Consumers should try to choose a faucet with a aerator when purchasing, a cítiť prietok vody s rukou dotykom. Prietok vody je mäkký a pení (the bubble content of the water flow) je bohatý, naznačujúc, že kvalita prevzdania je lepšia. The aerator generally consists of six layers, obvykle pozostávajúca z kovového sieťového krytu (čiastočne plast). Keď voda preteká cez sieťový kryt, je nakrájaný na veľké množstvo malých vodných stĺpcov so vzduchom medzi nimi, so that the water is not torn apart.
