金属松套式伸缩接头

采用金属铸造或焊接组成，松套部位选用梯形圆环橡胶密封圈，在压盖和螺栓的作用下，利用橡胶的压缩弹性变形原理，迫使密封圈变形于接头本体接头本体伸缩管外壁之间进行静密封，金属和密封圈严格按使用性能及用户要求选用，材质外部涂装高强度防腐漆料，各部连接螺栓为高强度碳钢或不锈钢制作，因为本体与伸缩管之间有一定间隙，使它具有一定的轴向和径向位移，在管道中能有效的补偿和缓解管道盲板推力，又能便于水泵，阀门的安装维修和更换，实为管道安装及运行*为理想的配套产品。

产品适用范围

因为该系列产品属金属制品，其有较高的抗拉和抗压强度，软密封性能优越，装卸方便等功能，被广泛应用于电力，冶金，给排水和污水处理等行业，主要作用于水泵与阀门和管道之间的连接，它在管道运行中有一定的多向位移作用，可以缓解管道运行中的盲板推力，对管道起到一定的保护，特别是对管道的安装和维修提供了极大的便利，但是，在水泵出口处和管道转角处应采用传力接头，因为传力接头通过传力螺栓能把启泵时的盲板推力传导到泵和管道各部位，避免推力集中于管道或泵的近端，发生冲击力损伤设备。

Metal Loosing Expansion Joint

Product Performance

The product is manufactured through welding or metal casting, ａnd the loosing part is sealed by echelon ring rubber. Operated by gland ａnd bolt ａnd based on the principle of rubber’s elastic deformation under pressure,the seal ring will be deformed ａnd static seal will be done between joint body ａnd expansion pipe wall. According to clients demand ａnd product performance ,metal ａnd seal ring mate-rials will be selected strictly. High –strength antifouling paint is painted outside ａnd the joint bolt is made of high-strength carbon steel or stainless steel. Since there is some space between body ａnd expansion., so axes ａnd radial displacement will appear. Inside pipes, it becomes available to compensate ａnd release pipe blind plate propulsion ａnd makes it easy to maintain ａnd change pump ａnd valve. Therefore , it is an ideal matching product for pipes’ instal-lation ａnd operation.

Applicable Scope

The metal product is functioned with pull ａnd pressure resistance ａnd excellent seal performance ａnd easy installation. Hence it is widely used in power, metallurgy, drainage ａnd sewage disposal to connect pump, valce ａnd pipe, etc. It also has some multi-directional displacement during pipes’ operation so as to release blind plate propulsion ａnd protect pipes, expecially it makes it easy to install ａnd maintain pipes. However , force-transferring joints shall be used on the pipe corner ａnd pump exit, because, the joints can transfer blind plate propulsion from pump start to pump ａnd pipe through force—transferring bolt ａnd prevent pull to ventralize close to pipe or pipe or damage equipment by impact force. Other joints can be selected freely for other position. Our tenet: your trust is our honor ａnd we will manufacture high—quality products for you.
