應用：

管(guan)(guan)(guan)接(jie)(jie)頭(tou)是管(guan)(guan)(guan)道(dao)(dao)與(yu)管(guan)(guan)(guan)道(dao)(dao)之間的(de)(de)(de)連(lian)(lian)接(jie)(jie)工具，是元(yuan)件(jian)和管(guan)(guan)(guan)道(dao)(dao)之間可以拆裝的(de)(de)(de)連(lian)(lian)接(jie)(jie)點。在(zai)管(guan)(guan)(guan)件(jian)中充當(dang)著不可或(huo)缺的(de)(de)(de)重要(yao)角色，它是液壓(ya)管(guan)(guan)(guan)道(dao)(dao)的(de)(de)(de)兩個主(zhu)要(yao)構成部(bu)分之一。管(guan)(guan)(guan)接(jie)(jie)頭(tou)用(yong)(yong)(yong)于(yu)(yu)儀表等(deng)(deng)直線(xian)(xian)連(lian)(lian)接(jie)(jie)，連(lian)(lian)接(jie)(jie)形式(shi)有承(cheng)插焊或(huo)螺紋連(lian)(lian)接(jie)(jie)。主(zhu)要(yao)用(yong)(yong)(yong)于(yu)(yu)小口徑的(de)(de)(de)低(di)壓(ya)管(guan)(guan)(guan)線(xian)(xian)，用(yong)(yong)(yong)于(yu)(yu)需經常裝拆的(de)(de)(de)部(bu)位、或(huo)作為使用(yong)(yong)(yong)螺紋管(guan)(guan)(guan)件(jian)管(guan)(guan)(guan)路的(de)(de)(de)最(zui)終(zhong)調整(zheng)之用(yong)(yong)(yong)。結構形式(shi)宜采用(yong)(yong)(yong)金屬(shu)面接(jie)(jie)觸密封結構，墊片密封的(de)(de)(de)結構形式(shi)通常用(yong)(yong)(yong)于(yu)(yu)輸送水、油、空氣等(deng)(deng)一般管(guan)(guan)(guan)路上，采用(yong)(yong)(yong)可鍛鑄鐵材(cai)料制造。此外，使用(yong)(yong)(yong)要(yao)求與(yu)價(jia)格等(deng)(deng)也是選用(yong)(yong)(yong)時考慮的(de)(de)(de)因(yin)素。

管接頭有著繁(fan)多的種(zhong)類，常用(yong)的管接頭一般(ban)可以分為(wei)硬管接頭和軟(ruan)管接頭兩種(zhong)。如(ru)果依照管接頭和管道的連接方(fang)式來分，硬管接頭有擴口式、卡(ka)套式和焊接式三種(zhong)，軟(ruan)管接頭則主要是扣壓(ya)式膠管接頭。

液(ye)壓系(xi)統中(zhong)管(guan)(guan)(guan)(guan)道(dao)(dao)和(he)管(guan)(guan)(guan)(guan)接頭的(de)連接方(fang)式也有(you)(you)不同，管(guan)(guan)(guan)(guan)道(dao)(dao)旋入(ru)端(duan)采用(yong)的(de)是連接螺(luo)紋。錐螺(luo)紋憑借(jie)著自己(ji)的(de)椎體旋緊并利用(yong)聚四氟乙烯等(deng)物質(zhi)進行密(mi)(mi)封(feng)(feng)操作，主要被(bei)應用(yong)在中(zhong)低壓的(de)液(ye)壓系(xi)統中(zhong)。細牙螺(luo)紋的(de)密(mi)(mi)封(feng)(feng)效(xiao)果非常好，經常被(bei)用(yong)于高壓系(xi)統中(zhong)，但(dan)它需要使(shi)(shi)(shi)用(yong)組合(he)墊圈(quan)或者O型圈(quan)來針對端(duan)面(mian)(mian)的(de)封(feng)(feng)閉工作，有(you)(you)時也會用(yong)到紫銅墊圈(quan),它比較(jiao)適合(he)在連接管(guan)(guan)(guan)(guan)壁比較(jiao)厚的(de)管(guan)(guan)(guan)(guan)道(dao)(dao)中(zhong)，其組成部分主要有(you)(you)接頭體、接管(guan)(guan)(guan)(guan)和(he)螺(luo)母(mu)。在使(shi)(shi)(shi)用(yong)時，將接頭體嵌入(ru)目(mu)標中(zhong)，配合(he)使(shi)(shi)(shi)用(yong)前面(mian)(mian)所說的(de)墊圈(quan)將端(duan)面(mian)(mian)密(mi)(mi)封(feng)(feng)，接頭體和(he)接管(guan)(guan)(guan)(guan)之間用(yong)橡(xiang)膠(jiao)密(mi)(mi)封(feng)(feng)，有(you)(you)時也會使(shi)(shi)(shi)用(yong)球(qiu)面(mian)(mian)密(mi)(mi)封(feng)(feng)的(de)方(fang)式進行。

由于管(guan)接(jie)頭(tou)屬(shu)于可拆裝(zhuang)式(shi)的(de)連接(jie)元(yuan)件，它(ta)在滿足正常的(de)連接(jie)穩固、密封性強、尺寸合(he)理、壓力損(sun)失小(xiao)、工(gong)藝性能好等等的(de)要(yao)(yao)(yao)(yao)求(qiu)之外(wai)，還必(bi)須要(yao)(yao)(yao)(yao)滿足拆裝(zhuang)便利的(de)要(yao)(yao)(yao)(yao)求(qiu)。因此，不要(yao)(yao)(yao)(yao)小(xiao)看那(nei)一個個小(xiao)小(xiao)的(de)管(guan)接(jie)頭(tou)，因為只有它(ta)的(de)存在才能支撐起整個液(ye)壓系(xi)統的(de)存在。
