Dunnage bag fill valve device with integral combination baffle, plug retainer, and bladder separator |
摘要 |
An inflatable dunnage bag having a relatively thin-film, flexible, gastight bladder is provided with a fill valve device extending from the exterior of the bag to the interior of the bladder. The fill valve device includes a hollow housing which is mounted on one end by means of a flange to the outer surface of one wall of the bladder. Within the housing there is an orifice and a plug member which is spring-biased in sealing engagement against the orifice. The plug member extends beyond the end of the housing and into the bladder. A flange on the end of the plug member in the bladder is substantially parallel to, and spaced away from, the mounting flange/bladder wall interface to provide a separation of the bladder walls, to deflect the filling gas to prevent impingement upon the bladder wall opposite the housing, and to provide an anti-blowout stop thereby preventing the plug member from being blown out of engagement with the valve housing when the bag is subjected to high compressive loads.
