總有好(hao)多(duo)客(ke)戶問這(zhe)兩個產品有什么區(qu)別，今天小(xiao)編就給大家簡(jian)單(dan)講解一下

廣范(fan)圍(wei)柔(rou)性(xing)補償(chang)接頭也叫壓蓋補償(chang)接頭，管(guan)(guan)道材質為鑄(zhu)鐵(tie)(tie)(tie)管(guan)(guan)，中間筒(tong)可(ke)以(yi)選(xuan)鋼筒(tong)、球(qiu)鐵(tie)(tie)(tie)筒(tong)、不(bu)銹(xiu)鋼筒(tong)。沒有管(guan)(guan)材限制，塑管(guan)(guan)、鋼管(guan)(guan)、鐵(tie)(tie)(tie)管(guan)(guan)等全部(bu)通用(yong)，適(shi)用(yong)管(guan)(guan)徑范(fan)圍(wei)大，耐腐蝕強(qiang)度(du)(du)(du)高(gao)，具有補償(chang)功能，減(jian)少(shao)囤貨量，適(shi)用(yong)于(yu)飲用(yong)水，中性(xing)液體(ti)和污(wu)水，可(ke)帶壓工(gong)作(zuo)，工(gong)作(zuo)壓力PN16，最高(gao)溫度(du)(du)(du)零下10攝(she)氏度(du)(du)(du)至(zhi)零上70攝(she)氏度(du)(du)(du)，因為不(bu)是單(dan)一口徑，不(bu)限管(guan)(guan)材所以(yi)應(ying)用(yong)特別多(duo)

伸縮(suo)接頭：伸縮接頭能(neng)夠很好地實現對各(ge)(ge)種新型工(gong)業管道系統(tong)中的建(jian)(jian)設，能(neng)為各(ge)(ge)種類(lei)型管道系統(tong)中的建(jian)(jian)設提供新型連接方(fang)式。因此(ci)獲得了各(ge)(ge)種類(lei)型使用(yong)用(yong)戶(hu)的廣泛認可

伸(shen)縮膨(peng)脹量(liang)大、承受溫度高、受壓面(mian)積力(li)度強。建(jian)筑(zhu)給排水工(gong)程(cheng)中(zhong)(zhong)(zhong)基(ji)礎(chu)混凝(ning)土澆(jiao)注或者預埋管(guan)(guan)(guan)道(dao)(dao)(dao)，在(zai)(zai)這些工(gong)程(cheng)管(guan)(guan)(guan)道(dao)(dao)(dao)受建(jian)筑(zhu)物基(ji)礎(chu)沉降，設備共(gong)振，地質(zhi)變(bian)化(hua)(hua)，管(guan)(guan)(guan)道(dao)(dao)(dao)介質(zhi)變(bian)化(hua)(hua)的過程(cheng)中(zhong)(zhong)(zhong)，管(guan)(guan)(guan)道(dao)(dao)(dao)分布(bu)的位置開始受力(li)，變(bian)形(xing)，扭(niu)曲破壞管(guan)(guan)(guan)道(dao)(dao)(dao)，預埋管(guan)(guan)(guan)道(dao)(dao)(dao)甚至(zhi)破裂(lie)給施工(gong)單(dan)位帶(dai)來(lai)極大的不便，為了克(ke)服這些困難(nan)，確保管(guan)(guan)(guan)道(dao)(dao)(dao)的安(an)全運(yun)行(xing)，使用(yong)(yong)伸(shen)縮器、伸(shen)縮接頭：它能在(zai)(zai)一定的范(fan)圍內軸向伸(shen)縮，克(ke)服管(guan)(guan)(guan)道(dao)(dao)(dao)各種角度移位、不同心、伸(shen)縮、膨(peng)脹。管(guan)(guan)(guan)道(dao)(dao)(dao)在(zai)(zai)伸(shen)縮器中(zhong)(zhong)(zhong)可以自(zi)由伸(shen)縮。一旦超過更大的伸(shen)縮量(liang)自(zi)身起到限位作(zuo)用(yong)(yong)。從而(er)保證管(guan)(guan)(guan)道(dao)(dao)(dao)安(an)全運(yun)行(xing)。
