止回閥是什么閥門？

止回閥(fa)是指啟(qi)閉件為圓形閥(fa)瓣并(bing)靠自(zi)身(shen)重量及介質壓力(li)產生動作來(lai)阻斷介質倒(dao)流(liu)的一(yi)種閥(fa)門。它(ta)是依(yi)著介質本身(shen)流(liu)動打(da)開(kai)的，依(yi)著介質本身(shen)不動而(er)關閉，所以(yi)它(ta)也是一(yi)種自(zi)動閥(fa)。

單向(xiang)(xiang)閥(fa)(fa)是(shi)止回(hui)閥(fa)(fa)當中(zhong)的一種(zhong)類型，單向(xiang)(xiang)閥(fa)(fa)是(shi)止回(hui)閥(fa)(fa)，但止回(hui)閥(fa)(fa)不(bu)一定是(shi)單向(xiang)(xiang)閥(fa)(fa)。

止(zhi)回閥型號字母表示什么(me)？
