耳軸(Dummy Support)種類型式與作用
耳軸主要用(yong)于(yu)水平敷設的管(guan)(guan)道(dao)(dao)承(cheng)(cheng)重(zhong)。當(dang)水平管(guan)(guan)道(dao)(dao)拐彎且其跨度超出標準要求的最大允(yun)(yun)許(xu)值(zhi)時(shi),可以借助于(yu)該(gai)形(xing)(xing)(xing)式(shi)(shi)(shi)的支(zhi)(zhi)架(jia)承(cheng)(cheng)重(zhong)。該(gai)支(zhi)(zhi)架(jia)一般僅作承(cheng)(cheng)重(zhong)用(yong),而且僅能用(yong)于(yu)允(yun)(yun)許(xu)支(zhi)(zhi)架(jia)與管(guan)(guan)子直接焊接的情況(kuang)。當(dang)管(guan)(guan)道(dao)(dao)有保(bao)溫時(shi),它可與滑動管(guan)(guan)托(tuo)配合(he)使用(yong),此時(shi)的滑動管(guan)(guan)托(tuo)形(xing)(xing)(xing)式(shi)(shi)(shi)與直接支(zhi)(zhi)承(cheng)(cheng)在(zai)管(guan)(guan)子上的形(xing)(xing)(xing)式(shi)(shi)(shi)相同(tong)。&n...
