機械三通

機械三通與普通三通作用(yong)一致。機(ji)(ji)械(xie)三(san)通(tong)(tong)(tong)分為溝槽機(ji)(ji)械(xie)三(san)通(tong)(tong)(tong)和(he)螺紋(wen)機(ji)(ji)械(xie)三(san)通(tong)(tong)(tong)。它可用(yong)于(yu)直接(jie)在鋼(gang)管上接(jie)出支管，在消防管道(dao)(dao)及噴淋管道(dao)(dao)的(de)安裝上有(you)較(jiao)多應用(yong)。在需要分流(liu)或合流(liu)的(de)時候可以采用(yong)機(ji)(ji)械(xie)三(san)通(tong)(tong)(tong)。

溝槽式三通、溝槽式四通、機械三通、機械四通等管件必須采用標準規格產品；支管接頭的開孔設施必須專門的開孔機。當支管管徑不符合標準規格時，可在接出管上異徑管等轉換支管管徑。首先在鋼管(guan)(guan)上用開(kai)(kai)孔(kong)(kong)機(ji)(ji)開(kai)(kai)孔(kong)(kong)，然后將機(ji)(ji)械(xie)三通(tong)卡入孔(kong)(kong)洞，孔(kong)(kong)四周由密封(feng)圈沿(yan)管(guan)(guan)壁密封(feng)。機(ji)(ji)械(xie)三通(tong)分絲接和溝槽式兩種。機(ji)(ji)械(xie)三通(tong)連(lian)接時，應檢查(cha)機(ji)(ji)械(xie)三通(tong)與孔(kong)(kong)洞的間隙(xi)，各部位(wei)應均勻，然后再緊固到位(wei)；機(ji)(ji)械(xie)三通(tong)開(kai)(kai)孔(kong)(kong)間距(ju)不應小于(yu)1m。

機械三通與溝槽三通區別

1、機械(xie)三(san)通可用(yong)于直接在(zai)鋼(gang)管上接出(chu)支管。

2、首先在鋼管(guan)(guan)上(shang)用開孔(kong)(kong)機開孔(kong)(kong)，然后將機械三通卡入孔(kong)(kong)洞，孔(kong)(kong)四周由密封(feng)(feng)圈沿管(guan)(guan)壁密封(feng)(feng)。機械三通分(fen)絲接和溝槽(cao)式(shi)兩種。

3、正三(san)通指支管(guan)與(yu)主管(guan)成90度的三(san)通。

4、溝槽式連接方(fang)式廣泛(fan)用于建筑內的消(xiao)火栓系(xi)統與噴淋系(xi)統。

支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)接(jie)(jie)(jie)頭(tou)是(shi)指在(zai)直(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)道中(zhong)部開(kai)孔后連(lian)(lian)接(jie)(jie)(jie)支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)鞍形拼合(he)式連(lian)(lian)接(jie)(jie)(jie)件，分(fen)為機(ji)(ji)械(xie)三(san)(san)通(tong)(tong)(tong)和機(ji)(ji)械(xie)四(si)通(tong)(tong)(tong)兩(liang)種類(lei)型。在(zai)設(she)計圖紙上一般不會(hui)標注出溝(gou)槽三(san)(san)通(tong)(tong)(tong)和機(ji)(ji)械(xie)三(san)(san)通(tong)(tong)(tong)的(de)。機(ji)(ji)械(xie)三(san)(san)通(tong)(tong)(tong)或機(ji)(ji)械(xie)四(si)通(tong)(tong)(tong)與支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)連(lian)(lian)接(jie)(jie)(jie)方式有(you)溝(gou)槽式連(lian)(lian)接(jie)(jie)(jie)和螺紋式連(lian)(lian)接(jie)(jie)(jie)兩(liang)種，當支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)道小于DN50，且主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)道直(zhi)徑大于分(fen)支(zhi)直(zhi)徑2倍時可用(yong)機(ji)(ji)械(xie)三(san)(san)通(tong)(tong)(tong)（直(zhi)接(jie)(jie)(jie)在(zai)主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)道上開(kai)孔，噴淋支(zhi)管(guan)(guan)(guan)(guan)(guan)(guan)與主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)連(lian)(lian)接(jie)(jie)(jie)用(yong)得多），其它情況得用(yong)溝(gou)槽三(san)(san)通(tong)(tong)(tong)。

這(zhe)里(li)(li)的(de)溝(gou)槽三(san)(san)(san)(san)(san)通(tong)就是(shi)正三(san)(san)(san)(san)(san)通(tong)（主(zhu)(zhu)支管(guan)(guan)(guan)中(zhong)心(xin)線成直角），因(yin)為(wei)不像UPVC管(guan)(guan)(guan)、鑄鐵管(guan)(guan)(guan)除(chu)正三(san)(san)(san)(san)(san)角還有Y三(san)(san)(san)(san)(san)通(tong)（斜三(san)(san)(san)(san)(san)通(tong)）、TY三(san)(san)(san)(san)(san)通(tong)。正三(san)(san)(san)(san)(san)通(tong)與鍍(du)鋅配件的(de)三(san)(san)(san)(san)(san)通(tong)叫法一(yi)樣，只是(shi)鍍(du)鋅三(san)(san)(san)(san)(san)通(tong)是(shi)絲(si)扣連(lian)接(jie)，而這(zhe)里(li)(li)正三(san)(san)(san)(san)(san)通(tong)是(shi)溝(gou)槽式(shi)連(lian)接(jie)，每個管(guan)(guan)(guan)道的(de)平口端(duan)環形溝(gou)槽由專(zhuan)門的(de)滾槽機加工成型，與管(guan)(guan)(guan)道連(lian)接(jie)需要3副相應規格卡箍才能(neng)完成一(yi)個接(jie)頭(tou)，適合主(zhu)(zhu)干管(guan)(guan)(guan)的(de)連(lian)接(jie)。

至于(yu)(yu)機(ji)械(xie)三(san)(san)(san)通(tong)(tong)(tong)(tong)主管(guan)(guan)(guan)上(shang)只(zhi)需用(yong)開孔(kong)機(ji)開孔(kong)無需開槽，而支(zhi)(zhi)管(guan)(guan)(guan)或開槽（溝槽式(shi)連(lian)(lian)接(jie)(jie)(jie)）或套絲(si)（螺紋(wen)(wen)式(shi)連(lian)(lian)接(jie)(jie)(jie)），適合主支(zhi)(zhi)管(guan)(guan)(guan)間的連(lian)(lian)接(jie)(jie)(jie)（如噴(pen)淋系統的噴(pen)淋支(zhi)(zhi)管(guan)(guan)(guan)）。另外還有一(yi)種小機(ji)械(xie)三(san)(san)(san)通(tong)(tong)(tong)(tong)，只(zhi)是把(ba)卡(ka)箍(gu)換成了U型卡(ka)，這種小機(ji)械(xie)三(san)(san)(san)通(tong)(tong)(tong)(tong)與支(zhi)(zhi)管(guan)(guan)(guan)連(lian)(lian)接(jie)(jie)(jie)還是以螺紋(wen)(wen)連(lian)(lian)接(jie)(jie)(jie)為主，可能沒有溝槽連(lian)(lian)接(jie)(jie)(jie)形式(shi)。正三(san)(san)(san)通(tong)(tong)(tong)(tong)一(yi)般(ban)指三(san)(san)(san)個接(jie)(jie)(jie)管(guan)(guan)(guan)直徑(jing)(jing)相同而異徑(jing)(jing)三(san)(san)(san)通(tong)(tong)(tong)(tong)則三(san)(san)(san)個接(jie)(jie)(jie)管(guan)(guan)(guan)直徑(jing)(jing)不完全相同。正三(san)(san)(san)通(tong)(tong)(tong)(tong)用(yong)于(yu)(yu)同一(yi)直徑(jing)(jing)管(guan)(guan)(guan)道連(lian)(lian)接(jie)(jie)(jie)之用(yong)，異徑(jing)(jing)三(san)(san)(san)通(tong)(tong)(tong)(tong)則用(yong)于(yu)(yu)不同直徑(jing)(jing)管(guan)(guan)(guan)道的連(lian)(lian)接(jie)(jie)(jie)。機(ji)械(xie)三(san)(san)(san)通(tong)(tong)(tong)(tong)連(lian)(lian)接(jie)(jie)(jie)的支(zhi)(zhi)管(guan)(guan)(guan)直徑(jing)(jing)絕(jue)不可能等于(yu)(yu)主管(guan)(guan)(guan)直徑(jing)(jing)。
