德國REXROTH力士樂壓力開關(guān)內(nèi)有一個閥片,既是敏感件又是動作執(zhí)行件。當(dāng)裝置啟動時(shí),管道出現(xiàn)冷卻凝結(jié)水,凝結(jié)水靠工作壓力推開閥片,迅速排放。當(dāng)凝結(jié)水排放完畢,蒸汽進(jìn)入疏水閥內(nèi),蒸汽的體積迅速擴(kuò)大,蒸汽比凝結(jié)水的流速大,使閥片上下產(chǎn)生壓差,閥片在蒸汽流速的吸力下迅速關(guān)閉。當(dāng)閥片關(guān)閉時(shí),閥片受到兩面壓力,閥片下面的受力面積小于上面的受力面積,因疏水閥汽里面的壓力來源于蒸汽壓力,所以閥片上面受力大于下面,閥片緊緊關(guān)閉。當(dāng)疏水閥汽里面的蒸汽降溫成凝結(jié)水,汽里面的壓力消失。凝結(jié)水靠工作壓力推開閥片,凝結(jié)水又繼續(xù)排放,循環(huán)工作,間斷排水。德國REXROTH力士樂壓力開關(guān)又被稱為壓力容器的zui終保護(hù)裝置。安全閥根據(jù)工作壓力能自動啟閉,一般安裝于封閉系統(tǒng)的設(shè)備或管路上保護(hù)系統(tǒng)安全。安全閥屬于自動閥類,主要用于鍋爐、壓力容器和管道上,控制壓力不超過規(guī)定值,對人身安全和設(shè)備運(yùn)行起重要保護(hù)作用。安全閥是一種安全保護(hù)用閥,它的啟閉件受外力作用下處于常閉狀態(tài),當(dāng)設(shè)備或管道內(nèi)的介質(zhì)壓力升高,超過規(guī)定值時(shí)自動開啟,通過向系統(tǒng)外排放介質(zhì)來防止管道或設(shè)備內(nèi)介質(zhì)壓力超過規(guī)定數(shù)值。當(dāng)設(shè)備或管道內(nèi)壓力超過規(guī)定值時(shí),即自動開啟泄壓,保證設(shè)備和管道內(nèi)介質(zhì)壓力在規(guī)定數(shù)值以內(nèi),防止發(fā)生事故。閥門自動開啟,介質(zhì)從中泄出、減壓;當(dāng)壓力回到正常值時(shí),彈簧壓力又將閥芯推向閥座,閥門自動關(guān)閉。
