雙向流硬(ying)碰硬(ying)旋(xuan)球(qiu)閥(fa)同(tong)時兼具蝶(die)閥(fa)、半球(qiu)閥(fa)、閘閥(fa)和截止閥(fa)的(de)功(gong)(gong)能和優點(dian)(dian)，又有自身*與(yu)眾不同(tong)的(de)強大功(gong)(gong)能和優點(dian)(dian)。體積小、重量輕(qing)、運輸、安裝、維護(hu)檢修方便(bian)、運行可靠 。

雙向承壓球面旋(xuan)轉(zhuan)閥廣泛應用于水(shui)(shui)泵出口端、管網系統(tong)(tong)、回(hui)收水(shui)(shui)系統(tong)(tong)、高(gao)位水(shui)(shui)槽、易水(shui)(shui)淹的(de)污水(shui)(shui)系統(tong)(tong)、防倒流(liu)系統(tong)(tong)等需雙向密(mi)封(feng)的(de)場(chang)合，可用于冶金(jin)、礦山、石化、化工、電力、環(huan)保(bao)、市政等行業作為(wei)管路啟閉和調節使用。

雙向硬密封旋球閥廣泛應(ying)用(yong)于(yu)水(shui)(shui)(shui)泵出口端、管網系統(tong)、回收(shou)水(shui)(shui)(shui)系統(tong)、高位(wei)水(shui)(shui)(shui)槽、易水(shui)(shui)(shui)淹的污水(shui)(shui)(shui)系統(tong)、防(fang)倒(dao)流(liu)系統(tong)等(deng)需雙向密封的場合，可用(yong)于(yu)冶金(jin)、礦山、石(shi)化(hua)、化(hua)工、電力、環保、市政等(deng)行(xing)業作為管路(lu)啟閉和調節(jie)使用(yong)。

旋(xuan)塞(sai)(sai)(sai)(sai)閥(fa)是關閉(bi)件或(huo)(huo)柱(zhu)塞(sai)(sai)(sai)(sai)形(xing)(xing)(xing)(xing)(xing)的(de)(de)旋(xuan)轉閥(fa)，通(tong)(tong)(tong)過(guo)旋(xuan)轉90度(du)使閥(fa)塞(sai)(sai)(sai)(sai)上的(de)(de)通(tong)(tong)(tong)道(dao)(dao)口與閥(fa)體上的(de)(de)通(tong)(tong)(tong)道(dao)(dao)口相同或(huo)(huo)分開，實現開啟或(huo)(huo)關閉(bi)的(de)(de)一(yi)(yi)種(zhong)閥(fa)門。旋(xuan)塞(sai)(sai)(sai)(sai)閥(fa)原理的(de)(de)閥(fa)塞(sai)(sai)(sai)(sai)的(de)(de)形(xing)(xing)(xing)(xing)(xing)狀可成(cheng)圓柱(zhu)形(xing)(xing)(xing)(xing)(xing)或(huo)(huo)圓錐(zhui)形(xing)(xing)(xing)(xing)(xing)。在(zai)圓柱(zhu)形(xing)(xing)(xing)(xing)(xing)閥(fa)塞(sai)(sai)(sai)(sai)中(zhong)，通(tong)(tong)(tong)道(dao)(dao)一(yi)(yi)般成(cheng)矩(ju)形(xing)(xing)(xing)(xing)(xing)；而在(zai)錐(zhui)形(xing)(xing)(xing)(xing)(xing)閥(fa)塞(sai)(sai)(sai)(sai)中(zhong)，通(tong)(tong)(tong)道(dao)(dao)成(cheng)梯形(xing)(xing)(xing)(xing)(xing)。這些形(xing)(xing)(xing)(xing)(xing)狀使旋(xuan)塞(sai)(sai)(sai)(sai)閥(fa)的(de)(de)結構變(bian)得輕巧，但同時也產 。
