quick opening Closure is applicable to the openings of pressure pipelines and pressure vessels. The end closure is a kind of mechanical device could be opened and closed quickly. It mainly consists of door, locking band, hub, safety interlock system, and opening and closing system.
This product absorbed advanced technology and adopted advanced design concepts, contracting and opening system. Compact, flexible, on the basis of ensuring the strength of the product reduced dimensions. When door locking achieved, there is no relative rotation between the seal face and seal. So easy to prevent damage of the seal and ensure sealing. The entire opening or closing process can be completed by one person without special tools within two minutes. Thus greatly reducing the labor intensity. This product is especially suitable for pipeline pig launcher and receiver, filter and the like.
