    • A cam valve in which a zero point adjustment of the valve is simply and easily made by finely vertically adjusting an actuator made up of a stepping motor and a cam mechanism. In the cam valve (1) of a stepping motor drive type, a stem (7) is vertically movably installed in a body (2) having an inflow path (2a), an outflow path (2b), a valve chamber (2c), and a valve seat (2d). The stem (7) is lowered by the actuator composed of the stepping motor (9) provided above the stem (7) and of the cam mechanism (10) for converting the rotational motion of the stepping motor (9) into linear motion and transmitting it to the stem (7). This causes a diaphragm (3) placed in the valve chamber (2c) or a valve body (30) placed at the lower end of the stem (7) to be in contact with the valve seat (2d). A lifting support mechanism (11) for liftably supporting the actuator is provided on a bonnet (5) covering the valve chamber (2c) of the body (2), and the lifting support mechanism (11) is provided with a fine height adjustment mechanism (12) for performing a fine adjustment of the height of the actuator relative to the stem (7).
    • 一种凸轮阀,其中通过精细垂直调节由步进电机和凸轮机构构成的致动器简单且容易地制造阀的零点调节。 在步进电机驱动型的凸轮阀(1)中,杆(7)可上下移动地安装在具有流入路径(2a),流出路径(2b),阀室(2c)的主体(2) ,以及阀座(2d)。 杆(7)由设置在杆(7)上方的步进电动机(9)和凸轮机构(10)所构成的致动器下降,用于将步进电动机(9)的旋转运动转换为直线运动并传递 它到茎(7)。 这使得放置在阀室(2c)中的隔膜(3)或放置在阀杆(7)的下端处的阀体(30)与阀座(2d)接触。 在覆盖主体(2)的阀室(2c)的发动机罩(5)上设置有用于可升降地支撑致动器的升降支撑机构(11),并且提升支撑机构(11)设置有精细的高度调节机构 (12),用于执行致动器相对于杆(7)的高度的微调。
