    • PURPOSE: Provided is an apparatus for controlling flow rate of a fluid to reach a proper level in order to preciously distribute the fluid into at least two streams with a desirable relative fixed ratio and to prevent elastic sealing parts from severe wear. CONSTITUTION: The apparatus(10) comprises valve block halfs(100, 102) spaced apart at an interval; spool type valve elements(12,14,16) arranged parallel to respective cylindrical bores(13,15,17) mounted into each of the valve blocks. The valve elements are arranged opposite to one another and reciprocally move on the block halfs(100, 102). The elements slide inside the bores(13,15,17) without any sealing means but, in order to prevent the fluid from introducing into the apparatus, have a center portion(21) with a diameter less than that of the bore. The center portion(21) extended from the half outward is enclosed by an elastic seal.
    • 目的:提供一种用于控制流体的流速达到适当水平的装置,以便将流体以优选的相对固定比例珍贵地分布到至少两个流中,并且防止弹性密封部件严重磨损。 构成:装置(10)包括间隔隔开的阀块半部(100,102); 平行于安装到每个阀块中的相应圆柱形孔(13,15,17)布置的阀芯型阀元件(12,14,16)。 阀元件彼此相对设置并且在块半部(100,102)上往复移动。 这些元件在没有任何密封装置的情况下在孔(13,15,17)内滑动,但是为了防止流体引入到装置中,具有直径小于孔的直径的中心部分(21)。 从半个外部延伸的中心部分(21)由弹性密封件包围。
