    Abstract: An adjustable gas injector (10) for injecting a gas into a liquid at a controlled rate. The injector (10) includes a housing (12) and a gas flow adjustment device (56). The housing (12) includes primarily a liquid inlet (14), a gas inlet (18), a gas/liquid mixture outlet (32), and a mounting device (44). A mixing chamber (36) is defined between the liquid inlet (14) and the mixture outlet (32). A liquid stream is directed through the chamber (36) where it is mixed with a gas. In the direction of flow, the mixing chamber (36) defines a first region (38) in which the diameter decreases, a throat (40), and a second region (42) in which the diameter increases. The gas inlet (18) opens into the chamber (36) proximate the throat (40). The gas inlet (18) defines first and second channels (26,30). The housing (12) defines an opening (52) collinear with at least a portion of the first channel (26) of the gas inlet (18). At least a portion of the opening (52) defines a threaded receptor (54). The gas flow adjustment device (56) includes a spring-biased-ball (58) seated within the opening (52) against the distal end (28) of the first gas inlet channel (26). A threaded insert (62) is engaged in the threaded receptor (54) to control the pressure applied to the spring (60), and thus control the flow rate of the gas into the chamber (36).

    Abstract translation: 一种用于以可控制的速率将气体注入液体的可调气体喷射器(10)。 喷射器(10)包括壳体(12)和气体流量调节装置(56)。 壳体(12)主要包括液体入口(14),气体入口(18),气体/液体混合物出口(32)和安装装置(44)。 混合室(36)限定在液体入口(14)和混合物出口(32)之间。 液体流被引导通过腔室(36),在那里与气体混合。 在流动方向上,混合室(36)限定直径减小的第一区域(38),喉部(40)和直径增加的第二区域(42)。 气体入口(18)在喉部(40)附近通向腔室(36)。 气体入口(18)限定第一和第二通道(26,30)。 壳体(12)限定与气体入口(18)的第一通道(26)的至少一部分共线的开口(52)。 开口(52)的至少一部分限定螺纹接收器(54)。 气流调节装置(56)包括抵靠在第一气体入口通道(26)的远端(28)上的位于开口(52)内的弹簧偏置球(58)。 螺纹插入件(62)接合在螺纹接收器(54)中以控制施加到弹簧(60)的压力,并且因此控制进入腔室(36)的气体的流速。
