溝(gou)槽(cao)管件(jian)(jian)可(ke)以(yi)分為(wei)起連(lian)(lian)接(jie)密封(feng)作(zuo)用(yong)和連(lian)(lian)接(jie)過渡作(zuo)用(yong)的管件(jian)(jian)，現在工(gong)業消防等方面(mian)(mian)廣泛(fan)使用(yong)溝(gou)槽(cao)管件(jian)(jian)進行管道連(lian)(lian)接(jie)，那么溝(gou)槽(cao)管件(jian)(jian)具體有哪些分類？在選(xuan)購時(shi)需要(yao)關注哪些方面(mian)(mian)呢？下面(mian)(mian)我們就來看一下。

    溝槽管(guan)(guan)件(jian)中的(de)(de)剛性接(jie)(jie)頭、機械三通、溝槽式法蘭等管(guan)(guan)件(jian)能夠進行管(guan)(guan)件(jian)之間的(de)(de)連(lian)(lian)接(jie)(jie)密封，這些管(guan)(guan)件(jian)利用(yong)橡膠密封圈與管(guan)(guan)道銜接(jie)(jie)，堵住縫(feng)隙，然后在密封圈外面套上(shang)卡箍并(bing)用(yong)螺栓(shuan)固定，這種(zhong)結(jie)構增強(qiang)了管(guan)(guan)道連(lian)(lian)接(jie)(jie)的(de)(de)密閉(bi)性，保證管(guan)(guan)道內的(de)(de)液體不(bu)會泄露，并(bing)且管(guan)(guan)內壓力(li)越(yue)大，管(guan)(guan)件(jian)連(lian)(lian)接(jie)(jie)就越(yue)牢固密閉(bi)性越(yue)好。還有彎(wan)頭、三通、四通、異徑(jing)管(guan)(guan)等起到連(lian)(lian)接(jie)(jie)過渡的(de)(de)作用(yong)，可以(yi)滿足(zu)各種(zhong)不(bu)同(tong)的(de)(de)管(guan)(guan)道連(lian)(lian)接(jie)(jie)，比如彎(wan)頭能夠使連(lian)(lian)接(jie)(jie)的(de)(de)管(guan)(guan)道改變方向，異徑(jing)管(guan)(guan)能連(lian)(lian)接(jie)(jie)起直徑(jing)不(bu)同(tong)的(de)(de)管(guan)(guan)件(jian)。

    不(bu)同種(zhong)類的(de)管(guan)(guan)(guan)件(jian)能(neng)夠滿(man)足不(bu)同的(de)連接需求，無(wu)縫鋼管(guan)(guan)(guan)、鍍鋅鋼管(guan)(guan)(guan)、焊接鋼管(guan)(guan)(guan)、不(bu)銹鋼管(guan)(guan)(guan)、銅管(guan)(guan)(guan)等(deng)都(dou)可(ke)以(yi)用溝槽式(shi)卡(ka)箍接頭進行連接。管(guan)(guan)(guan)件(jian)還可(ke)以(yi)進行柔性(xing)的(de)管(guan)(guan)(guan)路連接，柔性(xing)連接能(neng)隨著管(guan)(guan)(guan)道溫(wen)度變(bian)化(hua)時長度的(de)變(bian)化(hua)而(er)變(bian)化(hua)，不(bu)僅能(neng)緩沖撞擊震動還能(neng)保持管(guan)(guan)(guan)道連接的(de)密閉性(xing)。

    了(le)(le)解(jie)了(le)(le)溝(gou)槽管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)的(de)(de)種類后我們還(huan)不能準確(que)的(de)(de)辨別(bie)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)的(de)(de)好壞，所以在(zai)(zai)選購溝(gou)槽管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)時我們還(huan)需要(yao)了(le)(le)解(jie)更(geng)多方面。首(shou)先要(yao)保證管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)的(de)(de)柔韌(ren)(ren)性(xing)，我們可(ke)以用手敲擊管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)表(biao)(biao)面，如果管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)表(biao)(biao)面出(chu)現很小的(de)(de)凹凸變化就說明(ming)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)的(de)(de)韌(ren)(ren)性(xing)較(jiao)(jiao)好，可(ke)以選擇，韌(ren)(ren)性(xing)不好的(de)(de)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)很容(rong)易(yi)斷裂(lie)損壞。溝(gou)螺紋長(chang)(chang)度較(jiao)(jiao)長(chang)(chang)的(de)(de)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)質(zhi)量更(geng)好，Z好選擇表(biao)(biao)面鍍鋅的(de)(de)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)，因為(wei)鍍鋅管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)能夠有效減(jian)輕管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)的(de)(de)腐(fu)蝕，延長(chang)(chang)使(shi)用壽命。另(ling)外還(huan)要(yao)估(gu)計(ji)一下(xia)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)的(de)(de)重量，管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)較(jiao)(jiao)輕說明(ming)可(ke)能存在(zai)(zai)偷工減(jian)料的(de)(de)現象，管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)比較(jiao)(jiao)薄很容(rong)易(yi)斷裂(lie)，所以選擇重量合適的(de)(de)管(guan)(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)質(zhi)量比較(jiao)(jiao)可(ke)靠(kao)一些。
