分類
泄壓閥結(jié)構(gòu)主要有兩大類：彈簧式和杠桿式。
彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。

杠桿式是靠杠桿和重錘的作用力。
隨著大容量的需要，又有一種脈沖式泄壓閥，也稱為先導(dǎo)式泄壓閥，由主泄壓閥和輔助閥組成。當(dāng)管道內(nèi)介質(zhì)壓力超過規(guī)定壓力值時(shí)，輔助閥先開啟，介質(zhì)沿著導(dǎo)管進(jìn)入主泄壓閥，并將主泄壓閥打開，使增高的介質(zhì)壓力降低。
如果主管道水流壓力繼續(xù)增加，導(dǎo)閥開啟量也隨之加大 宋體;mso-font-kerning:0pt"> 使得主閥上腔與下腔的壓差更大，主閥開啟量也越大，系統(tǒng)泄壓更快。反之，如果主管道水流壓力減小 宋體;mso-font-kerning:0pt" lang="EN-US">(如室內(nèi)消火栓使用個(gè)數(shù)增加或開啟噴頭個(gè)數(shù)增多時(shí) 宋體;mso-font-kerning:0pt" lang="EN-US">)，導(dǎo)閥控制室壓力隨之減小，導(dǎo)閥開啟量變小。主閥上腔壓力增大，主閥閥瓣詢下關(guān)小，使主管道水流壓力穩(wěn)定在系統(tǒng)設(shè)計(jì)。
特點(diǎn)
準(zhǔn)確且保持不變的安全穩(wěn)定壓力，一旦超壓，泄壓閥能充分打開及時(shí)泄壓。 宋體;mso-font-kerning:0pt" lang="EN-US">
關(guān)閉速度可調(diào)，消除壓力波動(dòng)。
隔膜傳動(dòng)機(jī)構(gòu)將操作滯后現(xiàn)象減小到最小。
它可安裝在任何位置，不用改變壓力設(shè)定值或從管路上拆除就可進(jìn)行維修和檢查。
