溝槽管道安裝工藝

溝槽管道安裝工藝摘要：本文詳細(xì)介紹了溝槽管道的安裝工藝，供各位參考！關(guān)鍵字：溝槽管道安裝a.管道安安裝◆機(jī)具準(zhǔn)備備：選擇符合合要求滾槽機(jī)機(jī)、開孔機(jī)和和切管機(jī)；◆管道準(zhǔn)備備：垂直切割割管道，清潔潔和加工管端端凹槽，加工工時(shí)小心管道道爆裂，和出出現(xiàn)鋒利邊沿沿，鋒利邊沿沿可能損壞密密封圈，凹槽槽寬度和深度度，必須符合合凹槽技術(shù)標(biāo)標(biāo)準(zhǔn)。◆檢查和潤(rùn)潤(rùn)滑密封圈：：檢查密封圈圈，確保密封封圈規(guī)格正確確。在密封圈圈外部和內(nèi)部部密封唇上，涂涂薄薄一層潤(rùn)潤(rùn)滑劑。應(yīng)小小心不要將顆顆粒雜質(zhì)黏附附在密封圈表表面。使用潤(rùn)潤(rùn)滑劑作為密密封圈的配件件。優(yōu)良的密密封圈潤(rùn)滑劑劑是防止密封封圈磨損和可可能損傷的基基礎(chǔ)。（如下下圖）◆密封圈安安裝滑動(dòng)密封圈圈到管端，確確保密封唇不不要懸垂在管管端。（如下下圖）◆密封圈定定位將密封圈在在靠攏的兩側(cè)側(cè)管端上定位位后，把密封封圈拉到兩側(cè)側(cè)管端凹槽的的中心位置。密密封圈不應(yīng)進(jìn)進(jìn)入管道凹槽槽。（如下圖圖）◆安裝連接接器外殼把外殼合在在密封圈上，使使殼體卡口咬咬合在管道凹凹槽內(nèi)，插入入螺栓，用手手?jǐn)Q緊螺帽。（如如下圖）◆擰緊螺帽帽交替、均勻勻地?cái)Q緊兩側(cè)側(cè)螺帽，直到到螺栓底座金金屬面接觸，螺螺栓收緊。b.機(jī)械三三通、機(jī)械四四通安裝先從外殼上上去掉一個(gè)螺螺栓，松開另另一螺帽直到到與螺栓端頭頭平，將下殼殼旋離上殼約約90度，把上殼殼出口部分放放在管口開口口處對(duì)中并與與孔成一直線線，在沿管端端旋轉(zhuǎn)下殼（如如是機(jī)械四通通,下殼方法與與上殼相同）使使上下兩塊合合攏。c.法蘭片片安裝◆安裝法蘭蘭片:先松開兩側(cè)側(cè)螺絲，將法法蘭兩塊分開開，分別將兩兩塊法蘭片的的環(huán)形鍵部分分裝入開槽管管端凹槽里，再再把兩側(cè)螺絲絲插入擰緊，調(diào)調(diào)節(jié)兩側(cè)間隙隙相近?！舭惭b密封封圈將密封圈"C"形開口處背背對(duì)法蘭，沿沿管端方向推推入法蘭內(nèi)徑徑凹槽內(nèi)即可可d.選擇符符合要求的橡橡膠密封圈附附（表一）e.管外徑徑與溝槽加工工尺寸附（表表二）f.管道支支吊架安裝附附（表三）g.管道加加工尺寸附（表表五）h.質(zhì)量要要求◆管道安裝裝時(shí)應(yīng)考慮管管間隙量，也也就是鋼管的的膨脹量。◆管道安裝裝后要進(jìn)行試試壓檢查是否否泄漏。如有有泄漏其原因因如下：◆螺栓沒擰擰緊，卡箍接接觸面有間隙隙。◆溝槽加工工深度應(yīng)符合合要求。◆密封面不不應(yīng)有雜質(zhì)。◆鋼管端部部密封面有傷傷痕或溝線狀狀傷痕不能安安裝。◆密封圈不不能有啃圈。◆鋼管外徑徑不能超差?！艏庸ず箐撲摴芏瞬恐翜蠝喜劬嚯x不能能小?！舭惭b不符符合要求，超超過規(guī)定的轉(zhuǎn)轉(zhuǎn)角。◆鋼管開孔孔引分支.在管路中引引出分支,首先必須在在管道開孔,孔必須開在在管道中心線線上并且尺寸寸要正確,開孔要用專專用工具.附（表四）孔孔開好后檢查查孔周圍16mm范圍的管表表面清潔、光光滑、無污物物、皮屑、凸凸出物方可安安裝。表一橡膠密封圈圈的選擇橡膠原料料應(yīng)用范圍圍橡膠圈色色標(biāo)記天然橡膠膠用于-335℃～+80℃的水和無油油氣體黑色乙丙橡膠膠用用于-330℃～+100℃一般介質(zhì)、耐耐老化綠色丁晴橡膠膠用于-440℃～+120℃的油、油霧霧和煤氣橙色鹵化丁橡橡膠不含油、含含有多種稀酸酸的水和氣體體棕色氯橡膠用于-220℃-200℃以下化學(xué)物物品藍(lán)色白色丁晴晴橡膠不含碳黑黑、可用于食食品白色氯丁橡膠膠一定范圍圍內(nèi)的潤(rùn)滑油油及化學(xué)品黃色有機(jī)硅橡橡膠用于-440℃-250℃以下的不帶帶烴類的空氣氣紅色表二
