耐負(fù)壓橡膠軟接頭有哪些要求？

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

   耐負(fù)壓橡膠軟接頭要求很高，單純的橡膠是耐不行負(fù)壓的，比方方說管道內(nèi)徑是0.1kg的負(fù)壓，橡膠管體就會吸扁，跟管道向外的壓力是絕對不同的，所以，負(fù)壓內(nèi)徑必須增加負(fù)壓導(dǎo)流筒，簡單的說，負(fù)壓導(dǎo)流筒就是在橡膠接頭的內(nèi)徑增加一個碳鋼的管子，但是接頭的內(nèi)徑要比原來的內(nèi)徑小了，有了負(fù)壓導(dǎo)流筒，橡膠接頭就不會被吸扁，這樣橡膠接頭原來的隔振、伸縮效果也不會影響，一受到影響的就是接頭的內(nèi)徑稍稍變小。

  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.
