三通管的簡(jian)介、種類、結構

有三個(ge)開口的(de)管(guan)接頭(tou) 叫三通(tong)(tong)管(guan)。三通(tong)(tong)管(guan)廣泛用于輸送(song)液(ye)體、氣體的(de)管(guan)網中(zhong)。因(yin)輸送(song)介質(zhi)(zhi)不同，三通(tong)(tong)管(guan)的(de)材質(zhi)(zhi)分為：鑄(zhu)鐵、鑄(zhu)鋼、鑄(zhu)銅(tong)、鑄(zhu)鋁(lv)、塑料(liao)、玻璃等。

三通管簡介

（pipe tee （T）、three-way tube、three-way pipe），顧(gu)名思義就是(shi)有(you)三(san)個(ge)(ge)口(kou)子，也(ye)就是(shi)說(shuo)一(yi)個(ge)(ge)進口(kou)，兩(liang)(liang)個(ge)(ge)出口(kou)；或(huo)兩(liang)(liang)個(ge)(ge)進口(kou)，一(yi)個(ge)(ge)出口(kou)。化工管件的一(yi)種，有(you)T形與(yu)Y形，有(you)等徑管口(kou)，也(ye)有(you)異徑管口(kou)，用于三(san)條相同或(huo)不同管路匯集(ji)處。其主要的作用是(shi)改(gai)變流體方(fang)向的。

種類

三通(tong)(tong)按材(cai)(cai)(cai)質(zhi)可分為金屬(shu)材(cai)(cai)(cai)質(zhi)與非金屬(shu)材(cai)(cai)(cai)質(zhi)。金屬(shu)材(cai)(cai)(cai)質(zhi)的三通(tong)(tong)有碳鋼、不(bu)銹(xiu)鋼、合金鋼等(deng)，絲扣(kou)三通(tong)(tong)是瑪(ma)鋼標準(zhun)生產(chan)的，執行的國標是GB/12459-2005。非金屬(shu)材(cai)(cai)(cai)質(zhi)的三通(tong)(tong)有PVC、UPVC、PPR等(deng)。 　　

按(an)連接(jie)方式(shi)可分為卡(ka)扣式(shi)和螺紋連接(jie)兩種。 　　

按(an)形狀可分丁(ding)字型、人字型。

結構

金屬材(cai)質三通(tong)(tong)具有主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)和在主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)一(yi)側垂直(zhi)于主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)并(bing)與(yu)主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)連通(tong)(tong)設置(zhi)的支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)，在主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)出口方(fang)(fang)向(xiang)與(yu)支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)出口方(fang)(fang)向(xiang)交匯拐(guai)角處設置(zhi)閥(fa)門(men)，閥(fa)門(men)上設置(zhi)圓形(xing)閥(fa)片，閥(fa)片在管(guan)(guan)(guan)(guan)(guan)(guan)腔關閉(bi)狀態為(wei)與(yu)管(guan)(guan)(guan)(guan)(guan)(guan)腔內(nei)壁(bi)相互密封的結構。本實(shi)(shi)(shi)用(yong)(yong)(yong)新(xin)型(xing)簡(jian)化了(le)管(guan)(guan)(guan)(guan)(guan)(guan)路(lu)(lu)設置(zhi)，節(jie)約了(le)管(guan)(guan)(guan)(guan)(guan)(guan)路(lu)(lu)零部(bu)件用(yong)(yong)(yong)量，方(fang)(fang)便了(le)操作(zuo)，便于管(guan)(guan)(guan)(guan)(guan)(guan)路(lu)(lu)分路(lu)(lu)檢(jian)修及各支(zhi)路(lu)(lu)分階段供應(ying)。本實(shi)(shi)(shi)用(yong)(yong)(yong)新(xin)型(xing)除具有傳統三通(tong)(tong)管(guan)(guan)(guan)(guan)(guan)(guan)的作(zuo)用(yong)(yong)(yong)外，同時(shi)起到雙工位閥(fa)門(men)的作(zuo)用(yong)(yong)(yong)，即主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)與(yu)支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)輸出可(ke)任意選取之一(yi)為(wei)閉(bi)合、另一(yi)為(wei)暢通(tong)(tong)的工作(zuo)狀態；本實(shi)(shi)(shi)用(yong)(yong)(yong)新(xin)型(xing)還可(ke)任意調節(jie)主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)與(yu)支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)輸出的流量比(bi)，只要(yao)調節(jie)閥(fa)片在管(guan)(guan)(guan)(guan)(guan)(guan)腔內(nei)的角度即可(ke)實(shi)(shi)(shi)現。

用途

用(yong)于(yu)改變流(liu)體方向，可用(yong)于(yu)輸水(shui)(shui)管(guan)路、輸油管(guan)路及各(ge)種液體化工(gong)(gong)材料輸送管(guan)路。主要用(yong)于(yu)醫學、水(shui)(shui)利（節水(shui)(shui)灌溉(gai)、給水(shui)(shui)排水(shui)(shui)）、能源（石油、天然氣、核工(gong)(gong)業）、建(jian)筑等(deng)工(gong)(gong)程領域。
