A liquid-spraying system comprises an elongated tubular conduit means adapted for the flow of liquid therethrough, a tube wall of liquid-tight, .elastically resilient material, liquid feeding means connected to one of the ends of the conduit means, closing means for at least substantially closing off the other end of the conduit means, and a large number of perforations of substantially circular cross sectional area through the tube wall and leading from the conduit interior to outside of the external tube wall surface.
The tube wall is made of a liquid-tight, elastically resilient material which is non-swelling in contact with water of a temperature of 60°C or higher and with organic extraction solvents, and wherein the perforations are uniform and have an outlet of at most about 0.8 mm2, being small enough to produce capillary forces between water and the material of the surrounding tube wall sufficient to substantially prevent water filling the conduit interior from flowing out of the perforations while the water in the conduit interior is under ambient pressure, but being sufficiently large and of such configuration as to permit ejection of the liquid jet substantially free from trickling, when the liquid in the conduit interior is under excess pressure at least of the magnitude derived from a water main.
一种液体喷射系统包括一个用于液体流经的细长管状导管装置,一个由液密弹性材料制成的管壁,一个与导管装置的一端相连的进液装置,至少用于基本封闭导管装置另一端的封闭装置,以及大量横截面积基本为圆形的穿孔,这些穿孔穿过管壁,从导管内部通向管壁外表面的外部。
管壁由液密、弹性回弹材料制成,这种材料在与温度为 60°C 或更高的水和有机萃取溶剂接触时不会膨胀,其中的穿孔是均匀的,出口面积最多约为 0.8平方毫米,小到足以在水和周围管壁材料之间产生毛细管力,从而在导管内部的水处于环境压力下时,基本上防止充满导管内部的水从穿孔中流出,但大到足够大,其构造允许在导管内部的液体处于至少来自自来水管的过大压力下时,基本上无滴漏地喷射液体。
