            球墨鑄鐵管的安裝方法是什么

            來(lái)源: 時(shí)間:2019/07/01 次數:

              一、先截取相應長(cháng)度的球墨鑄鐵管,切開(kāi)后應確保直管兩端斷面與直管軸線(xiàn)筆直、斷口潤滑規整、無(wú)飛邊毛刺,以免劃傷橡膠密封圈;

              二、在球墨鑄鐵管的兩端插口上畫(huà)好刺進(jìn)深度標志線(xiàn),深度標志線(xiàn)的斷面與軸線(xiàn)相筆直,管件承口與直管插口端部連接處應保留大約5mm的間隙;

              三、將法蘭壓蓋、橡膠密封圈依次套人直管插口端,橡膠密封圈的上邊緣與直管插口上畫(huà)好的刺進(jìn)深度標志線(xiàn)對齊;

              四、裝置直管時(shí)將直管插口端刺進(jìn)管件承口內,裝置管件時(shí)將管件承口端套入直管插口,并堅持橡膠密封圈在承口內的深度相同;

              五、順管件指向直管的方向裝入螺栓,緊固螺栓時(shí)應對角交叉進(jìn)行,逐一逐次均勻緊固,使橡膠密封圈均勻受力。
