    • There is provided a fluid control apparatus which enables reducing widths of lines for further reducing space occupied by the apparatus. Support flow-channel blocks 9 and 10 are constituted by large block portions 25 and 27 which have openings of fluid flow channels 9a and 10a abutted against openings of fluid flow channels 11c and 11d in extended flow-channel blocks 11a and 11b with seal portions 20 interposed therebetween and, also, are abutted against lower surfaces of the extended flow-channel blocks 11a and 11b, and small block portions 26 and 28 which have lower surfaces flushed with the large block portions 25 and 27 and have heights smaller than those of the large block portions. The small block portions 26 and 28 are provided with male-screw-members insertion holes 26a and 28a for mounting the support flow-channel blocks 9 and 10 to a base member 30.
    • 提供了一种流体控制装置,其能够减少线路的宽度,以进一步减少由装置占据的空间。 支撑流路块9和10由大的块部分25和27构成,其具有在延伸的流动通道块11a和11b中与流体流动通道9a和10a的开口抵接的流体流动通道9a和10a的开口,密封部分20 并且还与延伸的流动通道块11a和11b的下表面邻接,并且具有较低表面的小块部分26和28被大块部分25和27冲洗并且具有比 大块部分。 小块部分26和28设置有用于将支撑流动通道块9和10安装到基部构件30的阳螺纹构件插入孔26a和28a。

    • The present invention provides a fluid controller which enables fine adjustments of low flow rates and enables a user to set desired low flow rates. Low-flow-rate piston stop-position setting means 12, which sets a position at which a low-flow-rate piston stops in upward movement thereof, includes: a low-flow-rate control screw 31 which is screwed in a through screw hole 15a provided in the top wall 15 of a casing 4 in such a way as to provide a gap between itself and the upper end surface of a valve rod 5, a tapered portion 32 provided at the tip end portion of the low-flow-rate control screw 31, a stopper piston 33 which has, in an upper surface thereof, a tapered portion 34 facing to the tapered portion 32 with a predetermined interval interposed therebetween and also has a lower surface 33a for restricting the upper position at which the low-flow-rate piston 8 stops, and a plurality of force transmission spherical members 35 which are interposed between the tapered portion 32 of the low-flow-rate control screw 31 and the tapered portion 34 of the stopper piston 33 for transmitting force therebetween.
    • 本发明提供了一种流体控制器,其能够精细地调节低流量并且使用户能够设定所需的低流量。 低流量活塞止动位置设定装置12,其设定低流量活塞在其向上运动中停止的位置,包括:流量控制螺杆31,其被拧入通孔中 设置在壳体4的顶壁15中的孔15a,以便在阀杆5的上端面之间提供间隙,设置在低流量阀的顶端部的锥形部32, 速度控制螺钉31,止动活塞33,其上表面具有以预定间隔插入的锥形部分34,锥形部分34以锥形部分32为中心,并具有用于限制低位的上部位置的下表面33a 流量活塞8停止,以及多个压力传递球形部件35,其插入在低流量控制螺钉31的锥形部分32和止动器活塞33的锥形部分34之间,用于在其间传递力。
