1、對(duì)有腐蝕性物質(zhì)易選用閥體分開(kāi)式、閥座可去處的、硬質(zhì)合金密封副的超高壓截止閥。 2、高溫、超高壓介質(zhì)的管路或裝置上宜選用高溫高壓截止閥。如火電廠、核電站，石油化工系統(tǒng)的高溫、高壓管路上。 3、有流量調(diào)節(jié)或壓力調(diào)節(jié)，對(duì)調(diào)節(jié)精度要求高，而且管路直徑又比較小，如公稱通經(jīng)≤50mm 的管路上，宜選用高溫高壓截止閥。 4、管路上對(duì)流阻要求嚴(yán)格的管路上。 5、城市建設(shè)中的供水、供熱工程上，公稱通經(jīng)常規(guī)與小口徑的管路。天津300lb美標(biāo)截止閥電站焊接截止閥可完成對(duì)介質(zhì)的調(diào)理和緊密切斷。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">電站焊接截止閥一旦處于開(kāi)啟狀態(tài)，它的閥座和閥瓣密封面之間就不再有接觸，因而它的密封面機(jī)械磨損較小，由于大部分截止閥的閥座和閥瓣比較容易修理或更換密封元件時(shí)無(wú)需把整個(gè)閥門從管線上拆下來(lái)，這對(duì)于閥門和管線焊接成一體的場(chǎng)合是很適用的。焊接截止閥城市建設(shè)中的供水、供熱工程上，公稱通經(jīng)較小的管路，可選用截止、平衡閥或柱塞閥，如公稱通經(jīng)小于150mm的管路上。較明顯的優(yōu)點(diǎn)是：在開(kāi)啟和關(guān)閉過(guò)程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。</p><p style="text-indent:25px">對(duì)于電站截止閥而言如電動(dòng)執(zhí)行器損壞應(yīng)立即維修，不可用活絡(luò)板手代替，以免損壞閥桿四方，啟閉不靈，以致在生產(chǎn)中發(fā)生危險(xiǎn)。某些介質(zhì)，在截止閥關(guān)閉后冷卻，使閥件收縮，操作人員就應(yīng)于適當(dāng)時(shí)間再關(guān)閉一次，讓密封面不留細(xì)縫，否則，介質(zhì)從細(xì)縫高速流過(guò)，很容易沖蝕密封面。操作時(shí)，如發(fā)現(xiàn)操作過(guò)于費(fèi)勁，應(yīng)分析原因。若填料太緊，可適當(dāng)放松，如閥桿歪斜，應(yīng)通知人員修理。有的截止閥，在關(guān)閉狀態(tài)時(shí)，關(guān)閉件受熱膨脹，造成開(kāi)啟困難；如必須在此時(shí)開(kāi)啟，可將閥蓋螺紋擰松半圈至一圈，消除閥桿應(yīng)力，然后板動(dòng)手輪。電站截止閥注脂時(shí)，常忽略壓力問(wèn)題。</p><div

2.電站截止閥結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕。 3.電站截止閥緊密可靠，閘閥的密封面材料基本上使用的是塑料、密封性能好，其在真空系統(tǒng)得到大范圍的使用。 4.電站截止閥操作方便，開(kāi)閉迅速，從全開(kāi)到全關(guān)只要旋轉(zhuǎn)90度，便于遠(yuǎn)距離的控制。 5.電站截止閥維修方便，閘閥結(jié)構(gòu)簡(jiǎn)單，密封圈一般都是活動(dòng)的，拆卸更換都比較方便。 6.電站截止閥現(xiàn)在若是在全開(kāi)或是全閉的狀況下，閥座密封面同球體會(huì)與介質(zhì)相隔離，這時(shí)，介質(zhì)通過(guò)時(shí)就不會(huì)引起閥門密封面的侵蝕。 7.電站截止閥適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。電站高壓截止閥屬于強(qiáng)制密封式閥門，在閥門關(guān)閉時(shí)，必須向閥瓣施加壓力。天津300lb美標(biāo)截止閥</p><p style="text-indent:25px">電站截止閥能有效減少裝置停車，降低成本。天津300lb美標(biāo)截止閥</p><p>
