金屬松套式伸縮接頭

采用金屬鑄造或焊接組成，松套部位選用梯形圓環(huán)橡膠密封圈，在壓蓋和螺栓的作用下，利用橡膠的壓縮彈性變形原理，迫使密封圈變形于接頭本體接頭本體伸縮管外壁之間進行靜密封，金屬和密封圈嚴格按使用性能及用戶要求選用，材質(zhì)外部涂裝高強度防腐漆料，各部連接螺栓為高強度碳鋼或不銹鋼制作，因為本體與伸縮管之間有一定間隙，使它具有一定的軸向和徑向位移，在管道中能有效的補償和緩解管道盲板推力，又能便于水泵，閥門的安裝維修和更換，實為管道安裝及運行最為理想的配套產(chǎn)品。

產(chǎn)品適用范圍

因為該系列產(chǎn)品屬金屬制品，其有較高的抗拉和抗壓強度，軟密封性能優(yōu)越，裝卸方便等功能，被廣泛應(yīng)用于電力，冶金，給排水和污水處理等行業(yè)，主要作用于水泵與閥門和管道之間的連接，它在管道運行中有一定的多向位移作用，可以緩解管道運行中的盲板推力，對管道起到一定的保護，特別是對管道的安裝和維修提供了極大的便利，但是，在水泵出口處和管道轉(zhuǎn)角處應(yīng)采用傳力接頭，因為傳力接頭通過傳力螺栓能把啟泵時的盲板推力傳導(dǎo)到泵和管道各部位，避免推力集中于管道或泵的近端，發(fā)生沖擊力損傷設(shè)備。

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.
