FAQs
我可以使用这些柔性橡胶联轴器代替屏蔽无轮毂耦合吗?
如果它是上面的地面安装或维修,则不应更换屏蔽无枢轴联轴器,柔性橡胶耦合。柔性橡胶联轴器用于地下。无毂或屏蔽联轴器可在地上或地下使用,因为屏蔽为联轴器提供额外的强度。
柔性橡胶耦合看起来比无轮毂耦合要厚。盾牌上的屏蔽在No-Hub耦合上是什么?
The shield was designed for the no-hub couplings to adjust to variations in diameters of the pipes to be joined and for added strength. When the bands are tightened the corrugations squeeze together and line up to lock against each other. This puts pressure both parallel and crossways against the gasket which in turn tightens against the pipe providing a reliable positive seal. The shield keeps the pipe from shifting and possibly cutting or breaking through the gasket and the gasket creates the seal and prevents the pipe from pulling out.
What is a no-hub connection?
No-Hub连接允许用于将漏极组件连接到铸铁或钢管(非螺纹)的无轮毂连接。No-Hub联轴器由橡胶套筒和由软管夹固定的不锈钢带组成。一种变型,称为柔性管连接器,由具有两个可调节钢带的氯丁橡胶套管组成,用于连接不同的材料,如将新塑料管连接到现有的铸铁排水管时。
为什么有用于这些联轴器的管尺寸,但是它们适合的管道的相应外径是不同的?
No-hub couplings were designed primarily to fit cast-iron pipe, but can also fit many types of plastic and steel pipe; the size of such pipe is determined by the "nominal" (or approximate) inside diameter of the pipe. We list the approximate outside diameters, too, so you'll be able to determine whether or not they will fit your pipe.
我可以使用禁枢纽耦合来代替我的柔性橡胶耦合吗?
只要两个管道尺寸匹配到屏蔽的无轮毂耦合尺寸,那么是的,您可以。但是,如果它是上面的地面安装或维修,则不应更换具有柔性橡胶耦合的无轮毂耦合。柔性橡胶联轴器用于地下,但无枢纽联轴器可在地上或地下使用。
为什么当似乎柔性橡胶耦合较厚时,No-Hub耦合有屏蔽且可以做到相同的工作?
设计用于No-Hub耦合,以调整到要连接的管道的直径的变化。当带拧紧带的波纹线时,这导致垫圈的平行和十字路口都引起压力,这反过来抵靠管道提供可靠的正密封。屏蔽保持管道换档,可能切割或破碎垫圈,垫圈产生密封并防止管道拉出。没有集线器连接柔性管连接器
