style="font-size:16px;">彈性座封閘閥軟密封閘閥為雙平行閘板閥，入口密封方式，入口閥板由密封套和卸力閥板組成為主密封閘板。密封套與卸力閥板同步移動但又不相連，管道壓力通過卸力閥板、調平力臂傳遞給出口面的閥座，這樣將大幅度的提高軟密封面的結合力。閥板外面套有耐腐蝕橡膠密封套。軟密封材料在啟閉過程中，與閥座保持有一定的距離，使軟密封材料在無磨擦無折壓的環(huán)境中工作。密封套將管道中輸送的液體與閥芯內的部件隔離，免受液體的腐蝕和雜質的阻塞。此閥的密封材料更換非常方便，所以使用壽命是一般閘閥的2倍以上。彈性座封閘閥關閉時，密封面可以只依靠介質壓力來密封,即只依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的，即閘閥關閉時，要依靠外力強行將閘板壓向閥座，以保證密封面的密封性。開啟閘閥時，當閘板提升高度等于閘閥通徑的1：1倍時，流體的通道完全暢通，但在運行時，此位置是無法監(jiān)視的。實際使用時，是以閥桿的頂點作為標志，即開不動的位置，作為它的全開位置。為考慮溫度變化出現鎖死現象,通常在開到頂點位置上,再倒回1/2－1圈,作為全開閘閥的位置。因</span><span

style="font-size:16px;">用在消防系統(tǒng)中的話，是球鐵軟密封閘閥合適還是灰鐵硬密封閘閥合適？軟密封閘閥和硬密封閘閥都可以用在消防系統(tǒng)中，軟硬密封的選擇根據介質和泄漏率，如果是自來水軟密封閘閥好一點。在自來水系統(tǒng)中閥體材質宜選用鑄鐵，更耐腐蝕，閥體材質是灰鐵還是球鐵一般按照壓力來選擇，消防水系統(tǒng)壓力一般都在1MPa以下，所以灰鐵就完全可以滿足使用要求，但是球鐵的力學性能更好點。另外要看價格和客戶需要。消防泵以離心泵為主。電機啟動，葉輪在電機的帶動下高速旋轉，葉輪中的介質在葉片驅動下隨葉輪一起旋轉并在離心力作用下被高速甩出葉輪出口，進入泵體壓水室，同時葉輪進口處的介質流向葉片并使葉輪進口處介質壓力降低。泵體吸入管內介質壓力高于葉輪進口處介質壓力，泵體吸入管內介質流向葉輪進口同時泵體吸入管內介質壓力降低。</span>
