彈簧式安全閥,全啟式安全閥,彈簧全啟式安全閥指依靠彈簧的彈性壓力而將閥的瓣膜或柱塞等密封件閉鎖,一旦當壓力容器的壓力異常后產(chǎn)生的高壓將克服安全閥的彈簧壓力,所以閉鎖裝置被頂開,形成了一個泄壓通道,將高壓泄放掉。根據(jù)閥瓣開啟高度不同又分為全起式和微起式兩種。全起式泄放量大,回彈力好,適用于液體和氣體介質(zhì),微起式只宜用于液體介質(zhì)。
功能特點它的功能是:當容器內(nèi)壓力超過某一定值時,依靠介質(zhì)自身的壓力自動開啟閥門,迅速排出一定數(shù)量的介質(zhì)。當容器內(nèi)的壓力降到允許值時,閥又自動關(guān)閉,使容器內(nèi)壓力始終低于允許壓力的上限,自動防止因超壓而可能出現(xiàn)的事故,所以安全閥又被稱為壓力容器的保護裝置。
