异径橡胶接头的主要功能及性能：异径橡胶接头又叫作为橡胶大小头，橡胶渐缩管。橡胶接头主要具有弹性好，位移量大，安装方便，平衡管道偏差等性能特点，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，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。

   Main function and performance of reducer rubber joint: reducer rubber joint is also known as rubber size head, rubber reducing pipe.Rubber joint mainly has good elasticity, large displacement, easy installation, balance pipe deviation and other performance characteristics, the product is installed in the pump moment, is used to prevent cavitation, and the size of the pump inlet head should be the same, this is to prevent the gas phase in the pipeline in the pump mouth, the formation of large bubble son into the pump cavity, damage 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.

   异径橡胶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。

   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.
