异径橡胶软接头又叫作为橡胶大小头，橡胶渐缩管。橡胶软接头主要具有弹性好，位移量大，安装方便，平衡管道偏差等.点，该产品在泵中所安装的时刻，是用来防气蚀的，且泵进口的大小头一样应该.没有危险装，这是防止管道内气相在泵口积聚，形成大气泡儿进入了泵腔，损伤泵。只有一种物质情形下才可以底没有危险装。那就是大小头后面直接接进步弯曲的弯头。这种物质情形下气相没有可能积聚。异径橡胶软接头在流体流动方向(即中轴线方向)的伸长或压缩。该产品在安装时可产生横向、轴向、角向位移，不受管道不通心，法兰不公平行的限制。橡胶大小头也可以大大下降管道系统的震动和噪声，可根本上解决各类管路的接口位移，轴向伸缩及不齐心度等问题。
Reducer rubber joint also known as the rubber size head, rubber reducer tube.Rubber joint has good elasticity, the main displacement quantity is big, easy to install, balance pipe deviation, etc., the product is installed in the pump, is used to prevent cavitation, and the size of the pump head should be same. There is no danger, this is to prevent the pipe gas phase in the pump inlet accumulation, form big bubbles into the pump chamber, and damage to the pump.Only in the case of a substance can it be safely contained.That is the size of the head directly behind the progressive bending of the elbow.The gas phase is not likely to accumulate in this case.Elongation or compression of reducer rubber joints in the direction of fluid flow (i.e., in the direction of the central axis).The product can produce lateral, axial and angular displacement during installation, and is not subject to the restrictions of pipe impaction and unfair flange.Rubber size head can also greatly reduce the vibration and noise of the pipeline system, can fundamentally solve all kinds of pipeline interface displacement, axial expansion and misalignment and other problems.
