style="text-indent:25px">安裝閥門(mén)的注意事項(xiàng)：1.閥門(mén)安裝方法錯(cuò)誤。例如截止閥或止回閥水(汽)流向與標(biāo)志相反，閥桿朝下安裝，水平安裝的止回閥采取垂直安裝，明桿閘閥或蝶閥手柄沒(méi)有開(kāi)、閉空間，暗裝閥門(mén)的閥桿不朝向檢查門(mén)。后果：閥門(mén)失靈，開(kāi)關(guān)檢修困難，閥桿朝下往往造成漏水。措施：嚴(yán)格按閥門(mén)安裝說(shuō)明書(shū)進(jìn)行安裝，明桿閘閥留足閥桿伸長(zhǎng)開(kāi)啟高度，蝶閥充分考慮手柄轉(zhuǎn)動(dòng)空間，各種閥門(mén)桿不能低于水平位置，更不能向下。暗裝閥門(mén)不但要設(shè)置滿足閥門(mén)開(kāi)閉需要的檢查門(mén)，同時(shí)閥桿應(yīng)朝向檢查門(mén)。2.安裝閥門(mén)的規(guī)格、型號(hào)不符合設(shè)計(jì)要求。例如閥門(mén)的公稱壓力小于系統(tǒng)試驗(yàn)壓力；給水支管當(dāng)管徑小于或等于50mm時(shí)采用閘閥；熱水采暖的干、立管采用截止閥；消防水泵吸水管采用蝶閥。后果：影響閥門(mén)正常開(kāi)閉及調(diào)節(jié)阻力、壓力等功能。甚至造成系統(tǒng)運(yùn)行中，閥門(mén)損壞被迫修理。措施：熟悉各類閥門(mén)的應(yīng)用范圍，按設(shè)計(jì)的要求選擇閥門(mén)的規(guī)格和型號(hào)。閥門(mén)的公稱壓力要滿足系統(tǒng)試驗(yàn)壓力的要求。按施工規(guī)范要求：給水支管管徑小于或等于50mm應(yīng)采用截止閥；當(dāng)管徑大于50mm應(yīng)采用閘閥。熱水采暖干、立控制閥應(yīng)采用閘閥，消防水泵吸水管不應(yīng)采用蝶閥。閥門(mén)注脂時(shí)，常忽略注脂效果問(wèn)題。注脂操作中壓力、注脂量、開(kāi)關(guān)位都正常。山東閥門(mén)生產(chǎn)廠家</p><p style="text-indent:25px">如手輪丟失，應(yīng)及時(shí)配齊，而不能夠用活扳手代替。蘇州閥門(mén)電裝哪家便宜</p><p style="text-indent:25px">截止閥工作原理：截止閥的閉合原理是, 依靠閥杠壓力, 使閥瓣密封面與閥座密封面緊密貼合, 阻止介質(zhì)流通。截止閥只許介質(zhì)單向流動(dòng), 安裝時(shí)有方向性。它的結(jié)構(gòu)長(zhǎng)度大于閘閥, 同時(shí)流體阻力大, 長(zhǎng)期運(yùn)行時(shí), 密封可靠性不強(qiáng)。截止閥分為三類 : 直通式、直角式及直流式斜截止閥。截止閥作用截止閥, 也叫截門(mén), 閥門(mén)對(duì)其所在的管路中的介質(zhì)起著切斷和節(jié)流的重要作用。截止閥是使用十分普遍的一種閥門(mén), 它之所以廣受歡迎, 是由于開(kāi)閉過(guò)程中密封面之間摩擦力小, 比較耐用, 開(kāi)啟高度不大, 制造容易, 維修方便, 不*適用于中低壓, 而且適用于高壓。試壓方法強(qiáng)度試驗(yàn)時(shí)，通常將組裝好的閥門(mén)放在試壓架中，打開(kāi)閥瓣，注入介質(zhì)至規(guī)定值，檢查閥體和閥蓋是否冒汗和滲漏，也可單件進(jìn)行強(qiáng)度試驗(yàn)。蘇州閥門(mén)電裝哪家便宜</p></p><br /><p>文章來(lái)源地址:
