style="text-indent:25px">閥門(mén)：按結(jié)構(gòu)種類分主要有：旋塞閥、閘閥、截止閥、球閥—用于開(kāi)啟或關(guān)閉管道的介質(zhì)流動(dòng)。止回閥(包括底閥)—用于自動(dòng)防止管道內(nèi)的介質(zhì)倒流。節(jié)流閥—用于調(diào)節(jié)管道介質(zhì)的流量。蝶閥—用于開(kāi)啟或關(guān)閉管道內(nèi)的介質(zhì)。也可作調(diào)節(jié)用。安全閥—用于鍋爐、容器設(shè)備及管道上，當(dāng)介質(zhì)壓力趔過(guò)規(guī)定數(shù)值時(shí)，能自動(dòng)排除過(guò)剩介質(zhì)壓力，保證生產(chǎn)運(yùn)行安全。減壓閥—用于自動(dòng)降低管道及設(shè)備內(nèi)介質(zhì)壓力。系使介質(zhì)經(jīng)過(guò)閥瓣的間隙時(shí)，產(chǎn)生阻力造成壓力損失，達(dá)到減壓目的。疏水器—用于蒸汽管道上自動(dòng)排除冷凝水，防止蒸汽損失或泄漏。按用途，根據(jù)閥門(mén)的不同用途可分：1. 開(kāi)斷用：用來(lái)接通或切斷管路介質(zhì)，如截止閥、閘閥、球閥、蝶閥等。2. 止回用：用來(lái)防止介質(zhì)倒流，如止回閥。3. 調(diào)節(jié)用：用來(lái)調(diào)節(jié)介質(zhì)的壓力和流量，如調(diào)節(jié)閥、減壓閥。4. 分配用：用來(lái)改變介質(zhì)流向、分配介質(zhì)，如三通旋塞、分配閥、滑閥等。5. 安全閥：在介質(zhì)壓力超過(guò)規(guī)定值時(shí)，用來(lái)排放多余的介質(zhì)，保證管路系統(tǒng)及設(shè)備安全，如安全閥、事故閥。6. 他特殊用途：如疏水閥、放空閥、排污閥等。根據(jù)加工要求，部分零部件需要做拋光處理，表面不能有加工毛刺等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東閥門(mén)電裝哪家便宜,閥門(mén)"

安全閥：安全閥類的作用是防止管路或裝置中的介質(zhì)壓力超過(guò)規(guī)定數(shù)值，從而達(dá)到安全保護(hù)的目的。(4) 調(diào)節(jié)閥：調(diào)節(jié)閥類包括調(diào)節(jié)閥、節(jié)流閥和減壓閥，其作用是調(diào)節(jié)介質(zhì)的壓力、流量等參數(shù)。(5) 分流閥：分流閥類包括各種分配閥和疏水閥等，其作用是分配、分離或混合管路中的介質(zhì)。(6)排氣閥：排氣閥是管道系統(tǒng)中必不可少的輔助元件，普遍應(yīng)用于鍋爐、空調(diào)、石油天然氣、給排水管道中。往往安裝在制高點(diǎn)或彎頭等處，排除管道中多余氣體、提高管道路使用效率及降低能耗。用無(wú)紡布或者精密濾紙沾分析純酒精對(duì)逐個(gè)零部件進(jìn)行擦拭，直至沒(méi)有臟色。九江閥門(mén)電裝銷售廠家</p><p
