style="text-indent:25px">在更換閥芯前，要先找到這個(gè)水龍頭的水源開關(guān)，然后關(guān)掉，以免更換的時(shí)候噴水。然后找到冷然水的按鈕或者是塑料帽，用小刀片將其輕輕撬下來，這樣就能看到里面的螺絲拆掉把手后就能看到里面的閥芯，有的閥芯外面還有層固定的外殼蓋，把蓋子拆掉就可以了。然后就能看到固定閥芯的卡件，卡件上一般有四個(gè)爪子，用尖嘴鉗的兩邊將兩個(gè)爪子卡住，然后順時(shí)針旋轉(zhuǎn)就能夠取下卡件。將卡件卸下后，就能拆下壞的閥芯了，然后將新的閥芯安裝上，將前面的步驟反過來操作，把其他的組件重新安裝回去，將水龍頭把手安上后，打卡水源閥門，試試是否漏水，沒有問題后將把手鎖緊，裝好冷熱水塑料帽即可。</p><p 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(gè)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(gè)直徑1.5mm左右的小孔，其功能是讓閥芯運(yùn)動(dòng)時(shí)起到透吸氣作用，維護(hù)管理時(shí)應(yīng)注意千萬不要將小孔塞住，否則影響閥芯的正常運(yùn)行。閥芯的減壓保障系統(tǒng)是重中之重，工作人員在維護(hù)管理時(shí)要遵守規(guī)范，否則操作不當(dāng)會(huì)直接影響閥芯的正常運(yùn)轉(zhuǎn)工作。減壓閥中的閥芯是實(shí)現(xiàn)控制壓力的主要零部件之一。</p><div

style="text-indent:25px">閥芯在完全開啟時(shí)，具有較小的流阻。當(dāng)開啟在大約15°~70°之間時(shí)，又能進(jìn)行靈敏的流量控制，因而在大口徑的調(diào)節(jié)領(lǐng)域，閥芯的應(yīng)用非常普遍。由于閥芯閥板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)的閥芯可用于帶懸浮固體顆粒的介質(zhì)。依據(jù)密封件的強(qiáng)度，也可用于粉狀和顆粒狀介質(zhì)。閥芯適用于流量調(diào)節(jié)。由于閥芯在管中的壓力損失比較大，估算大約是閘閥的三倍，因此在選擇閥芯時(shí)，應(yīng)充分考慮管路系統(tǒng)受壓力損失的影響，還應(yīng)考慮關(guān)閉時(shí)閥板承受管路介質(zhì)壓力的強(qiáng)度。此外，還必須考慮在高溫下彈性閥座材料所承受工作溫度的限制。請(qǐng)求閥芯作為流量控制運(yùn)用，主要的是正確選擇閥門的尺寸和類型。長(zhǎng)沙國產(chǎn)閥芯修理</p><p
