產(chǎn)品型號(hào)：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(chēng)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(mén)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(mén)處于關(guān)閉狀態(tài)時(shí)，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(duì)閥門(mén)的污染; ③ 在工作壓力下，閥門(mén)處于全開(kāi)或全關(guān)狀態(tài)時(shí)，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(dòng)泄壓 閥門(mén)中腔停滯的介質(zhì)由于溫度升高，而出現(xiàn)異常升高時(shí)，閥座或閥體上安裝的安全閥可以自動(dòng)泄壓。 6、防火結(jié)構(gòu) 采用雙重密封，當(dāng)發(fā)生火災(zāi)時(shí)，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(shí)，通過(guò)注脂閥注入密封脂可以起瞬時(shí)應(yīng)急密封作用。 8、閥桿加長(zhǎng) 閥桿加長(zhǎng)適用于地下安裝及低溫介質(zhì)用，加長(zhǎng)尺寸，根據(jù)需要確定。操作方式有手動(dòng)、氣動(dòng)、電動(dòng)、氣液聯(lián)動(dòng)、液動(dòng)等。 二、主要零件材料
