   耐负压橡胶软接头有哪些要求？

   What are the requirements for negative pressure resistant rubber soft joints?

   耐负压橡胶软接头要求很高，单纯的橡胶是耐不行负压的，比方方说管道内径是0.1kg的负压，橡胶管体就会吸扁，跟管道向外的压力是绝对不同的，所以，负压内径必须增加负压导流筒，简单的说，负压导流筒就是在橡胶接头的内径增加一个碳钢的管子，但是接头的内径要比原来的内径小了，有了负压导流筒，橡胶接头就不会被吸扁，这样橡胶接头原来的隔振、伸缩效果也不会影响，一受到影响的就是接头的内径稍稍变小。

  Resistance to negative pressure high requirement of soft rubber joints, pure rubber is not negative pressure resistance, said fang fang, pipe diameter is 0.1 kg of negative pressure, the rubber hose body will absorb flat, it is absolutely different with that of the outward, so the negative pressure inside diameter must be increased negative pressure diversion cone, in short, the negative pressure diversion tube is in the inner diameter of the rubber joint increase a carbon steel pipe, but the inner diameter of the joint is smaller than the inner diameter of the original, with negative pressure diversion tube, rubber joint will not be flat, so that the rubber joint vibration isolation, expansion effect will not affect the original and the affected is the inner diameter of the joint is slightly smaller.
