Paddle 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, hub, safety interlock system, and opening and closing system.
This product absorbed advanced technology and adopted advanced design concepts. Compact, flexible, on the basis of ensuring the strength of the product reduced dimensions. The door is consist of two coaxial plates, the draw bolt cause locking plate rotating round the coaxial shaft to drive the blind flange to move in-line to close and lock the door. No- dynamic seal prevents damage of the seal and ensure sealing. The entire opening or closing process can be completed by one person without special tools within several minutes. Thus greatly reduces the labor intensity. It could be divided into vertical and horizontal types. The vertical type is mainly used to launch and receive pipeline pigs, and horizontal is for filter and the like.
