進(jìn)口安全閥介紹

（閥門(mén)概述、工作原理、技術(shù)參數(shù)、特點(diǎn)、型號(hào)、規(guī)格）

進(jìn)口安全閥是一種由進(jìn)口靜壓開(kāi)啟的自動(dòng)泄壓防護(hù)裝置,它是壓力容器zui為重要的安全附件之一,它的功能是：當(dāng)容器內(nèi)壓力超過(guò)某一定值時(shí),依靠介質(zhì)自身的壓力自動(dòng)開(kāi)啟閥門(mén),迅速排出一定數(shù)量的介質(zhì)。當(dāng)容器內(nèi)的壓力降到允許值時(shí),閥又自動(dòng)關(guān)閉,使容器內(nèi)壓力始終低于允許壓力的上限,自動(dòng)防止因超壓而可能出現(xiàn)的事故,所以安全閥又被稱(chēng)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(dòng)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(dòng)閥類(lèi),主要用于鍋爐、壓力容器和管道上,控制壓力不超過(guò)規(guī)定值,對(duì)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(guò)規(guī)定值時(shí)自動(dòng)開(kāi)啟,通過(guò)向系統(tǒng)外排放介質(zhì)來(lái)防止管道或設(shè)備內(nèi)介質(zhì)壓力超過(guò)規(guī)定數(shù)值。當(dāng)設(shè)備或管道內(nèi)壓力超過(guò)規(guī)定值時(shí)，即自動(dòng)開(kāi)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)，閥門(mén)自動(dòng)開(kāi)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(mén)自動(dòng)關(guān)閉。安全閥類(lèi)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。
