style="text-indent:25px">壓力開關(guān)是消防噴淋系統(tǒng)中的主要部件，安裝在消防噴淋系統(tǒng)的濕式報(bào)警閥中。消防壓力開關(guān)的作用是當(dāng)消防噴淋管道里的壓力小于供水端壓力時(shí)，壓力開關(guān)會(huì)自動(dòng)動(dòng)作，并且將動(dòng)作信號(hào)反饋回火災(zāi)自動(dòng)報(bào)警系統(tǒng)主機(jī)上?？刂浦鳈C(jī)收到信號(hào)啟動(dòng)消防噴淋泵進(jìn)行加壓。輸入模塊，有稱監(jiān)視模塊，用于檢測設(shè)備工作狀態(tài)，通常監(jiān)測使用常開信號(hào)設(shè)備，一旦被監(jiān)控設(shè)備動(dòng)作，常開端閉合，則向主機(jī)發(fā)出設(shè)備動(dòng)作的報(bào)警信息。壓力開關(guān)：當(dāng)報(bào)警閥動(dòng)作，報(bào)警管路通水，管內(nèi)壓力大于設(shè)定值時(shí)，開關(guān)動(dòng)作，向系統(tǒng)反饋報(bào)警閥工作。信號(hào)閥：為避免人員誤操作，導(dǎo)致閥門關(guān)閉，系統(tǒng)不能正常工作，故在閥門上安裝信號(hào)反饋裝置，避壓力開關(guān)怎么調(diào)壓力。</p><p style="text-indent:25px">壓力開關(guān)的使用方法1、壓力開關(guān)擁有比較高的精確度和穩(wěn)定的性能，被普遍地應(yīng)用在石油化工行業(yè)、冶金行業(yè)、電力行業(yè)以及供水行業(yè)對(duì)不同的液體和其他的表面壓力和絕壓進(jìn)行測量和控制，是一種智能化的檢測控制儀表。2、壓力開關(guān)的工作原理是如果壓力開關(guān)系統(tǒng)里面的壓力高于或者是比初始設(shè)定的安全的壓力值小的話，壓力開關(guān)里面的感應(yīng)器里面的碟片可以及時(shí)地感應(yīng)到并且發(fā)生警報(bào)。3、同時(shí)會(huì)發(fā)生移動(dòng)，通過和導(dǎo)桿相互連接，使得壓力開關(guān)的接頭接通電源或者是和電源相互斷開。壓力開關(guān)LED顯示當(dāng)前壓力或液位值。</p><div
