sealing area

As an improved feature, V cup packings of rubber with fabric and back-up rings of polytetrafluoroethylene are adopted, The total contact area between the sealing lips and the bushing is only 25 to 33 percent of the original packing-bushing contact area.

改进后的密封结构，采用V形橡胶夹布盘根和聚四氟乙烯扶正板，盘根唇部与衬套的接触面积仅为原来的25～33%，减少了发热量。扶正板能自润滑。

The breech lock closure type heat exchanger is characterized by reliable sealing performance, easy dismantling and assembling, high utilization ratio of heat exchange area and small grounding.

螺纹锁紧环换热器具有密封性能可靠，拆装方便，换热面积的利用率高，结构紧凑，占地面积小等特点。

When serving as the lubricant, MF would maintain at the friction area because of the magnetic force. The lubrication effect is so excellent that MF has been widely used in mechanical sealing and lubrication.

磁性液体作为润滑剂时，能够在磁力作用下保持在摩擦区域中，润滑效果良好，因此被成功的应用于轴承机械的密封和润滑中。

If too much solder is used, it may flow past tube stop and clog sealing area.

如果使用的焊料太多, 那么有些焊料可能会流过管道阻挡部位,并堵塞密封区域.

The valve outlet sealing area is also flat. The nut fits on the nipple so the shoulder of the nipple rests on the pushing surface of the nut.

阀门排气口密封区域也是平的。螺母配合在管接口上，因而管接口靠在螺母的螺纹正面。
