產(chǎn)品型號：Q47F 產(chǎn)品口徑：DN50-DN800 產(chǎn)品壓力：PN1.6-PN10.0MPA 產(chǎn)品材質(zhì)：碳鋼 CF8 固定球閥，球體帶有固定軸的球閥，稱為固定球閥。固定球閥主要用于高壓大口徑。根據(jù)閥座密封圈的安裝不同，固定球閥可以有兩種結(jié)構(gòu)：球體前密封的閥座，球體后密封的閥座1、結(jié)構(gòu)特點(diǎn) 2、整體結(jié)構(gòu) 如圖5所示。具有全通道、緊急密封、防火等特點(diǎn)。 3、全通徑 閥門流道孔直徑與管和徑內(nèi)徑一致，更于管線清掃。 4、阻塞與排泄 閥門處于關(guān)閉狀態(tài)時，上下游側(cè)的閥座使流體阻斷，閥體中腔的積治物可以排泄，排泄裝置如下機(jī)能： ① 事前可檢查閥座是否泄漏損傷; ②減少介質(zhì)更換對閥門的污染; ③ 在工作壓力下，閥門處于全開或全關(guān)狀態(tài)時，可更換閥桿部填料函。（如圖5所示排泄裝置是排污塞） 5、自動泄壓 閥門中腔停滯的介質(zhì)由于溫度升高，而出現(xiàn)異常升高時，閥座或閥體上安裝的安全閥可以自動泄壓。 6、防火結(jié)構(gòu) 采用雙重密封，當(dāng)發(fā)生火災(zāi)時，非金屬閥座燒損后，介質(zhì)將球體壓緊在閥體上的金屬密封面阻止介質(zhì)大量漏出，符合API607規(guī)定。 7、緊急密封 閥座及閥桿密封件出現(xiàn)損傷而引起泄漏時，通過注脂閥注入密封脂可以起瞬時應(yīng)急密封作用。 8、閥桿加長 閥桿加長適用于地下安裝及低溫介質(zhì)用，加長尺寸，根據(jù)需要確定。操作方式有手動、氣動、電動、氣液聯(lián)動、液動等。 二、主要零件材料
