    • A piezoelectric valve is provided to reduce power consumption compared to conventional solenoids and obtain rapid and precise response while reducing manufacturing cost. In a piezoelectric valve, an internal hole(19) is formed in a valve body(11) so that piezoelectric actuators(17a,17b) can be opposite to each other. Armatures(16a,16b) are slid by a guide(13) provided at the tip ends of the inner sides of the inserted piezoelectric actuators. A bolt(15b) and a connector(18) are engaged with the valve body. The bolt sets a displacement expanding space at the tip ends of the outer sides of the piezoelectric actuators. The connector is adapted to apply a voltage. One side of the valve body is engaged with a valve seat and the bolt. The armatures are vertically moved by the displacement difference of the piezoelectric actuators. A ground area(21) is provided at one end of the armature. The shape of one side of the ground section of the armature is concave and the shape of the other side of the ground section is convex.
    • 提供一种压电阀,以减少与传统螺线管相比的功耗,并获得快速准确的响应,同时降低制造成本。 在压电阀中,在阀体(11)中形成内孔(19),使得压电致动器(17a,17b)能够彼此相对。 电枢(16a,16b)通过设置在插入的压电致动器的内侧的末端处的引导件(13)滑动。 螺栓(15b)和连接器(18)与阀体接合。 螺栓在压电致动器的外侧的前端设置位移膨胀空间。 连接器适用于施加电压。 阀体的一侧与阀座和螺栓接合。 电枢通过压电致动器的位移差垂直移动。 地面区域(21)设置在衔铁的一端。 电枢的接地部分的一侧的形状是凹形的,并且接地部分的另一侧的形状是凸形的。

    • PURPOSE: A high differential pressure control valve for an offshore plant using multiple loaded discs is provided to improve pressure reducing effects by increasing the energy loss of fluid flowing in a disc body. CONSTITUTION: A high differential pressure control valve for an offshore plant using multiple loaded discs includes a disc body (40) formed by piling up multiple discs (10). Multiple first flow path grooves (21) are formed on one surface of each disc in multiple rows and are separated from each other. Multiple second flow path grooves (31) are formed on the other surface of each disc in the radial direction of the disc and are separated from each other. The second flow path grooves connect the first flow path grooves to each other.
    • 目的:提供使用多个装载盘的海上工厂的高压差控制阀,以通过增加在盘体中流动的流体的能量损失来改善减压效果。 构成:用于使用多个装载盘的海上工厂的高压差控制阀包括通过堆叠多个盘(10)形成的盘体(40)。 在多个盘的一个表面上形成多个第一流路槽(21)并且彼此分离。 在盘的径向上的每个盘的另一个表面上形成多个第二流路槽(31),并且彼此分离。 第二流路槽将第一流路槽彼此连接。
