style="font-size:16px;">消聲止回閥主要適用于高層建筑供水、排水系統(tǒng)，消防管道給水系統(tǒng)等。此消聲止回閥可有效地防止介質(zhì)倒流而產(chǎn)生破壞性水錘，保護(hù)水泵和管道其它設(shè)備。1、閥瓣采用頭”外形設(shè)計(jì)，閥體采用“腰鼓”外形設(shè)計(jì)，改善介質(zhì)流向，降低流阻系數(shù)。2、閥門采用短結(jié)構(gòu)形式，雖然水頭損失比升降式靜音止回閥稍大些，但體積小、價(jià)格便宜。3、結(jié)構(gòu)緊湊，導(dǎo)向軸與導(dǎo)向架之間裝有非金屬潤(rùn)滑套，閥瓣升降靈活，不會(huì)產(chǎn)生抱死現(xiàn)象。4、骨架式橡膠密封圈直接鑲嵌在閥體上，避免了介質(zhì)長(zhǎng)時(shí)間對(duì)密封圈的直接沖刷，使用壽命明顯延長(zhǎng)，堅(jiān)固、耐用。5、閥瓣啟閉行程短，可以有效的防止水錘產(chǎn)生。6、適用于給排水系統(tǒng)，高層建筑管網(wǎng)，可安裝在泵的出口處，結(jié)構(gòu)稍加改動(dòng)，可做為吸水底閥使用，但不適用于污水管網(wǎng)。</span> 安裝止回閥是為了保證水泵內(nèi)部水流的流向，從而保障水泵的正常工作。民勤止回閥廠家供應(yīng)</p><p style="text-indent:25px">升降式止回閥。升降式止回閥的閥體多與截止閥閥體相似。民勤止回閥廠家供應(yīng)</p><p
