介紹:
?壓力開(kāi)關(guān)?是一種壓力控制設(shè)備,主要用于檢測(cè)和輸出壓力信號(hào),實(shí)現(xiàn)報(bào)警和顯示功能。它通過(guò)利用內(nèi)外壓力差來(lái)控制開(kāi)關(guān)的接通或斷開(kāi),全壓力時(shí),壓力開(kāi)關(guān)內(nèi)的感應(yīng)片會(huì)在壓差作用下發(fā)生移動(dòng),進(jìn)而推動(dòng)開(kāi)關(guān)接點(diǎn)動(dòng)作,實(shí)現(xiàn)接通或斷開(kāi)。當(dāng)壓力恢復(fù)到安全范圍內(nèi)時(shí),感應(yīng)從而實(shí)現(xiàn)對(duì)壓力的測(cè)量和控制。壓力開(kāi)關(guān)廣泛應(yīng)用于各種工業(yè)領(lǐng)域,如石油化工、冶金電力、水利供水等,甚至在航天軍工等領(lǐng)域也有應(yīng)用?。壓力開(kāi)關(guān)的工作原理基于壓力差。當(dāng)內(nèi)部壓力高于或低于額定安片會(huì)自動(dòng)復(fù)位,開(kāi)關(guān)也隨之復(fù)位,確保設(shè)備安全運(yùn)行?。
