H44X(SFCV)橡(xiang)膠(jiao)瓣(ban)(ban)(ban)主要由閥(fa)體、閥(fa)蓋及橡(xiang)膠(jiao)瓣(ban)(ban)(ban)三(san)種(zhong)主要零(ling)件組成。其中橡(xiang)膠(jiao)瓣(ban)(ban)(ban)由鋼板(ban)、鋼棒及強化尼龍布(bu)做襯底，外層披覆橡(xiang)膠(jiao)制成，閥(fa)瓣(ban)(ban)(ban)開關壽命可達100萬次(ci)。該(gai)H44X(SFCV)橡(xiang)膠(jiao)瓣(ban)(ban)(ban)止(zhi)回閥(fa)采用(yong)全流(liu)面積(ji)式設計，具有水(shui)(shui)頭損(sun)失小(xiao)。不易堆積(ji)雜物，維修簡(jian)便等特性(xing)。該(gai)H44X(SFCV)橡(xiang)膠(jiao)瓣(ban)(ban)(ban)止(zhi)回閥(fa)主要適(shi)用(yong)于給(gei)排(pai)水(shui)(shui)系(xi)統，可安裝于水(shui)(shui)泵出水(shui)(shui)口(kou)處，以防(fang)止(zhi)倒流(liu)及水(shui)(shui)錘對泵損(sun)害。該(gai)H44X(SFCV)橡(xiang)膠(jiao)瓣(ban)(ban)(ban)止(zhi)回閥(fa)還可安裝在(zai)蓄水(shui)(shui)池(chi)進出水(shui)(shui)管的旁通(tong)管上，以防(fang)止(zhi)池(chi)水(shui)(shui)倒流(liu)至(zhi)給(gei)水(shui)(shui)系(xi)統中。
