    摘要: A leak detection system (50) including a flow accelerator for directing and accelerating leaking gas toward a sampling probe (70). A probe input tube (72) is inserted into one end (62B) of a larger diameter adapter tube (60) to position the end of the tube (72) past a suction opening (62D). The other end (62A) of the adapter tube is positioned to receive leaking gas. A suction is applied to the suction opening, which tends to draw the leaking gas into the adapter tube end (62A). Some of the leaking gas is drawn into the suction opening, and some into the end of the sampling tube. The suction causes the leaking gas to be accelerated toward the sampling probe input port. The suction can be created by a venturi (66C) through which is passed a gas under pressure. The acceleration of the gas through the venturi creates the suction. The flow accelerator significantly reduces the time required to locate small gas leaks.
