ADJUSTABLE FLUID JET APPARATUS

WIPO Patent Application WO/2012/058809

A1

An adjustable fluid jet apparatus comprises a driving device (6) with a control device, a nozzle (2), an extending joint (7) of the nozzle, a cavity (12) of a receiving chamber, a diffuser (13), a valve rod (3') and a needle valve (3). The shell of the cavity (12) of the receiving chamber is a three-way joint (1) with a T type, which includes a first opening (1a), a second opening (1b) and a third opening (1c). The first opening (1a) and the second opening (1b) are hermetically sleeved on the extending joint (7) of the nozzle and a conical inlet section (4a) of the diffuser. The valve rod (3') and the needle valve (3) pass through the extending joint (7) of the nozzle and the nozzle (2). The moving range of the end part of the needle valve (3) extends at least from the throat part (2a) of the nozzle into a mixing section (4). One end part of valve rod (3') is connected to the driving device (6) with a control device. The cross sectional area of the throat part (2a) of the nozzle and the mixing section (4) can be adjusted at the same time. The adjustable fluid jet apparatus can improve efficiency and has high machining accuracy.
