單向閥
安裝位置
單向閥就是止回閥 旋啟式止回閥安裝位置不受限制，通常安裝于水平管路，但也可以安裝于垂直管路或傾斜管路上。
注意事項(xiàng)
安裝止回閥時(shí)，應(yīng)特別注意介質(zhì)流動(dòng)方向，應(yīng)使介質(zhì)正常流動(dòng)方向與閥體上指示的箭頭方向相*，否則就會(huì)截?cái)嘟橘|(zhì)的正常流動(dòng)。底閥應(yīng)安裝在水泵吸水管路的底端。
止回閥關(guān)閉時(shí)，會(huì)在管路中產(chǎn)生水錘壓力，嚴(yán)重時(shí)會(huì)導(dǎo)致閥門、管路或設(shè)備的損壞，尤其對(duì)于大口管路或高壓管路，故應(yīng)引起止回閥選用者的高度注意。
止回閥只供防止各類管路或設(shè)備上流體介質(zhì)逆流的單向啟閉閥。

3）先導(dǎo)式電磁閥：
原理：通電時(shí)，電磁力把先導(dǎo)孔打開(kāi)，上腔室壓力迅速下降，在關(guān) 閉件周圍形成上低下高的壓差，流體壓力推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開(kāi)；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過(guò)旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。
特點(diǎn)：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。

止回閥用途廣泛，有很多種類，下面說(shuō)的是供水和熱力常用的止回閥：
1、彈簧式：液體由下而上，依靠壓力頂起彈簧控制的閥瓣，壓力消失后，彈簧力將閥瓣壓下，封閉液體倒流。常用于通徑較小的止回閥。
2、重力式：和彈簧式相似，依靠閥瓣的自身重力封閉，防止倒流。
3、旋啟式：液體在閥體內(nèi)直通，依靠壓力頂開(kāi)一側(cè)的旋轉(zhuǎn)閥瓣，壓力失去后，閥瓣依靠自重回位，反向的液體壓力封閉閥瓣。
4.塑料隔膜式: 外殼和隔膜均為塑料.一般外殼為ABS,PE,PP,NYLON, PC.隔膜有硅樹(shù)脂,氟樹(shù)脂等。
其它的單向閥（止回閥），如排污的止回閥，人防的防爆閥和液體使用的止回閥的原理是大同小異。

電磁閥選型首先應(yīng)該依次遵循安全性，可靠性，適用性，經(jīng)濟(jì)性四大原則，其次是根據(jù)六個(gè)方面的現(xiàn)場(chǎng)工況（即管道參數(shù)、流體參數(shù)、壓力參數(shù)、電氣參數(shù)、動(dòng)作方式、特殊要求進(jìn)行選擇）。
選型依據(jù)：
1、根據(jù)管道參數(shù)選擇電磁閥的：通徑規(guī)格（即DN）、接口方式
1）按照現(xiàn)場(chǎng)管道內(nèi)徑尺寸或流量要求來(lái)確定通徑（DN）尺寸；
2）接口方式，一般>DN50要選擇法蘭接口，≤DN50則可根據(jù)用戶需要自由選擇。
