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，鄭州電動截止閥生產(chǎn)廠家，鄭州電動截止閥生產(chǎn)廠家。 4、管路上對流阻要求嚴格的管路上。 5、城市建設中的供水、供熱工程上，公稱通經(jīng)常規(guī)與小口徑的管路。電站焊接截止閥密封結(jié)構(gòu)中密封腔內(nèi)安裝件較少。鄭州電動截止閥生產(chǎn)廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">電站焊接截止閥一旦處于開啟狀態(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無需把整個閥門從管線上拆下來，這對于閥門和管線焊接成一體的場合是很適用的。焊接截止閥城市建設中的供水、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)點是：在開啟和關閉過程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。廣東2500lb
