A guide part separated from the valve body (first flow control part) is in sliding contact with the housing, so that the valve body is not subjected to a force acting in the expansion and contraction direction of the valve rod. Therefore, even if the guide part is abraded due to the force in the expansion and contraction direction of the valve rod, the micro-flow characteristic does not change, and the change of the micro-flow characteristic of the height adjusting valve can be prevented for a long time.
由于使与阀体(第一流量控制部)分开的引导部与壳体滑动接触,所以阀体不受到作用于阀杆的伸缩方向的力。由此,即使受到阀杆的伸缩方向的力而使引导部发生偏磨损,也不会使微小流量特性发生变化,能够长期防止高度调节阀的微小流量特性的变化。
