抗硫安全閥的定義:
抗硫安全閥是根據(jù)壓力系統(tǒng)的工作壓力自動啟閉,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。當(dāng)設(shè)備或管道內(nèi)壓力超過抗硫安全閥設(shè)定壓力時(shí),自動開啟泄壓,保證設(shè)備和管道內(nèi)介質(zhì)壓力在設(shè)定壓力之下,保護(hù)設(shè)備和管道正常工作,防止發(fā)生意外,減少損失。
抗硫安全閥的作用:
抗硫安全閥在系統(tǒng)中起安全保護(hù)作用。當(dāng)系統(tǒng)壓力超過規(guī)定值時(shí),抗硫安全閥打開,將系統(tǒng)中的一部分氣體/流體排入大氣/管道外,使系統(tǒng)壓力不超過允許值,從而保證系統(tǒng)不因壓力過高而發(fā)生事故。
