閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)是一種(zhong)常見的閥(fa)(fa)(fa)(fa)(fa)(fa)門類(lei)(lei)型，其分(fen)類(lei)(lei)可以(yi)(yi)(yi)(yi)從多(duo)個(ge)角度進(jin)(jin)行。1.按密封方式分(fen)類(lei)(lei)，閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)可以(yi)(yi)(yi)(yi)分(fen)為軟密封和硬密封兩種(zhong)。2.按規格型號分(fen)類(lei)(lei)，閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)主要(yao)包括(kuo)球(qiu)閥(fa)(fa)(fa)(fa)(fa)(fa)、安全(quan)閥(fa)(fa)(fa)(fa)(fa)(fa)、減壓(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)(fa)、止回閥(fa)(fa)(fa)(fa)(fa)(fa)等(deng)。其中，球(qiu)閥(fa)(fa)(fa)(fa)(fa)(fa)用于控制、調(diao)節管(guan)(guan)(guan)道介質(zhi)(zhi)流(liu)(liu)動，廣泛應用于水(shui)利、電力(li)、化(hua)工、鋼(gang)鐵(tie)等(deng)領域。安全(quan)閥(fa)(fa)(fa)(fa)(fa)(fa)是一種(zhong)自(zi)動閥(fa)(fa)(fa)(fa)(fa)(fa)，當(dang)管(guan)(guan)(guan)道內壓(ya)(ya)(ya)力(li)超過(guo)一定值時(shi)，它(ta)會自(zi)動開啟排放介質(zhi)(zhi)，避(bi)免管(guan)(guan)(guan)道設備因壓(ya)(ya)(ya)力(li)過(guo)高而損壞。止回閥(fa)(fa)(fa)(fa)(fa)(fa)則通(tong)過(guo)自(zi)身重量或介質(zhi)(zhi)壓(ya)(ya)(ya)力(li)來(lai)防止管(guan)(guan)(guan)道介質(zhi)(zhi)倒流(liu)(liu)，起到保護管(guan)(guan)(guan)道的作用。減壓(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)(fa)則能(neng)將進(jin)(jin)口壓(ya)(ya)(ya)力(li)降到需要(yao)的壓(ya)(ya)(ya)力(li)范圍內，并(bing)保持(chi)壓(ya)(ya)(ya)力(li)穩定。3.按使用方式分(fen)類(lei)(lei)，閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)可以(yi)(yi)(yi)(yi)分(fen)為手(shou)動、電動、傘齒輪、信(xin)號、鎖(suo)閉(bi)、溝槽(cao)、承插、明桿、暗桿等(deng)多(duo)種(zhong)類(lei)(lei)型。4.按材質(zhi)(zhi)分(fen)類(lei)(lei)，閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)可以(yi)(yi)(yi)(yi)分(fen)為不(bu)銹(xiu)鋼(gang)、球(qiu)墨鑄(zhu)鐵(tie)、碳(tan)鋼(gang)等(deng)材質(zhi)(zhi)。此外(wai)，楔式閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)是一種(zhong)具有(you)雙閘(zha)(zha)板(ban)的閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)類(lei)(lei)型，其結(jie)構復雜但密封性(xing)能(neng)好，適用于中高壓(ya)(ya)(ya)流(liu)(liu)體的控制。旋(xuan)塞閥(fa)(fa)(fa)(fa)(fa)(fa)則是依靠旋(xuan)塞體繞閥(fa)(fa)(fa)(fa)(fa)(fa)體中心(xin)線(xian)旋(xuan)轉以(yi)(yi)(yi)(yi)達到開啟與關閉(bi)的目的，用于切(qie)斷(duan)、分(fen)配和改變介質(zhi)(zhi)流(liu)(liu)向。總(zong)的來(lai)說，閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)的分(fen)類(lei)(lei)多(duo)種(zhong)多(duo)樣，可以(yi)(yi)(yi)(yi)根據(ju)不(bu)同(tong)的需求(qiu)和場景(jing)選(xuan)擇適合的閘(zha)(zha)閥(fa)(fa)(fa)(fa)(fa)(fa)類(lei)(lei)型。
