style="text-indent:25px">在一開始選擇的時候就要慎重挑選陶瓷閥芯的。1、看表面的光亮度。水龍頭的閥體均由黃銅鑄成，表面鍍鎳和鉻。選購時，要注意表面的光澤，手摸時應(yīng)無毛刺、無氣孔、無氧化斑點。2、輕輕轉(zhuǎn)動手柄，看看是否輕便靈活。3、檢查水龍頭的各個零部件，尤其是主要零部件裝配是否緊密，應(yīng)無松動感覺。好的水龍頭的閥體、手柄全部采用黃銅精制，自重較沉，挑選陶瓷閥芯要有凝重感。水龍頭在接通水源前很難識別是否有滲漏，可以通過檢查其各連接部件有無松動來鑒別其好壞。因為這種松動式可能導(dǎo)致水龍頭滲漏的直接原因。識別產(chǎn)品標(biāo)記。一般正規(guī)商品均有生產(chǎn)廠家的品牌標(biāo)識以便識別和防止假冒。而一些非正規(guī)產(chǎn)品或質(zhì)次的產(chǎn)品往往*粘貼紙質(zhì)的標(biāo)簽，甚至無任何標(biāo)記。選購時一定要注意辨別。安徽壓調(diào)門的閥芯固定閥芯鎖緊帽的水處理閥，包括在閥體的閥芯腔上端連有的閥芯鎖緊帽。</p><div

style="text-indent:25px">注意閥芯的減壓保障系統(tǒng)。無論選用比例式還是可調(diào)式閥芯，其減壓比P1∶P2不宜選擇過大，一般應(yīng)控制在5∶1之內(nèi)。超過這個范圍易產(chǎn)生氣蝕現(xiàn)象，損壞閥件，產(chǎn)生嘯叫噪音。有些活塞式閥芯，制造廠在其閥體上加工一個直徑1.5mm左右的小孔，其功能是讓閥芯運動時起到透吸氣作用，維護管理時應(yīng)注意千萬不要將小孔塞住，否則影響閥芯的正常運行。閥芯的減壓保障系統(tǒng)是重中之重，工作人員在維護管理時要遵守規(guī)范，否則操作不當(dāng)會直接影響閥芯的正常運轉(zhuǎn)工作。</p><p style="text-indent:25px">有的水龍頭采用德國進口的陶瓷閥芯，售價在600元以上;如果是表面鍍金或者古銅色的比較好水龍頭，售價達到2000多元。雖然國家強制標(biāo)準(zhǔn)要用陶瓷閥芯，但是仍有衛(wèi)浴店在用其他材料生產(chǎn)閥芯。市面上的水龍頭普遍采用銅鍍絡(luò)材質(zhì)，價格也因品牌、用料、款式的不同而不同。水龍頭一般分為洗手盆、洗菜盆、淋浴三種不同的使用對象，價格差距也十分懸殊。普通小店的水龍頭價格從幾十元到一兩百元，一般的品牌店售價則是三四百元，比較好品牌的水龍頭少則六百元，多則數(shù)千元。閥芯作為水龍頭的重要部件，很大程度決定了水龍頭的使用質(zhì)量及壽命。</p><div
