style="text-indent:25px">止回閥種類：①蝶式雙瓣止回閥主要用在高層建筑給水管路中，含有腐蝕性介質(zhì)和污水的流體管網(wǎng)中使用。②升降式靜音止回閥是用在給排水工程質(zhì)量要求高的管線上;同時(shí)可安裝在泵的出口處，要求壓力(PN2.5Mpa)相對(duì)高的管網(wǎng);是防水錘止回閥的好產(chǎn)品。③升降式消聲止回閥適用于高層建筑給排水系統(tǒng)中及泵的出口處，不適合污水管路場(chǎng)合。④臥式止回閥適用于潛水、排水、排污泵，特別適用于污水和污泥系統(tǒng)。⑤旋啟式橡膠止回閥應(yīng)用在城市用水管網(wǎng)系統(tǒng);不適合沉積物多的污水管線。⑥旋啟單瓣止回閥使用范圍很廣，可安裝在給排水、石油、化工、冶金、工業(yè)等管路上</p><p style="text-indent:25px">止回閥是指依靠介質(zhì)本身流動(dòng)而自動(dòng)開(kāi)、閉閥瓣，用來(lái)防止介質(zhì)倒流的閥門，又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動(dòng)閥門，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動(dòng)電動(dòng)機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄放。主要作用止回閥在水泵供水系統(tǒng)中的作用是防止高壓水回流對(duì)水泵葉輪的沖擊。系統(tǒng)在運(yùn)行中由于某種原因，水泵突然停止運(yùn)轉(zhuǎn)時(shí)，泵內(nèi)壓力消失，與水泵出口相連的高壓水就會(huì)反向流回水泵。水泵出口裝有止回閥時(shí)它會(huì)立即關(guān)閉，防止高壓水反向流回水泵。止回閥在熱水系統(tǒng)的作用是防止熱水回流到管道中。如果是PVC管很可能燙壞管道，甚至可能傷人，特別是在太陽(yáng)能熱水器系統(tǒng)中。電站止回閥按結(jié)構(gòu)劃分，可分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種。</p><div
