TWO-VALVED NIPPLE FOR DRAWING-OFF LIQUEFIED GAS FROM A RESERVOIR |
摘要 |
The invention relates to a nipple comprising a sealing valve (20 min ) closed by a return spring (23) and a flow limiter (30 min ) cooperating with a calibrated spring (34) assuring the flow-limiting function. According to the invention in the lower part of the housing (10) a seat (12) is provided against which the sealing valve (20 min ) rests. The flow limiter (30 min ) is completely contained inside the volume defined by the housing. Furthermore, elastic means, such as a flexible washer (40), are interposed between the two valves to apply the flow limiter against its seat (11 min ) in fully closed position of the nipple. This arrangement makes it possible, in particular, to provide a simple metal-to-metal contact for the flow limiter, a thereby avoiding the adhesive problems encountered with elastomer joints. |
