    • PURPOSE: A check valve is provided to discharge fluid smoothly by forming a space inside an opening/closing side. CONSTITUTION: An inlet(12), and an outlet(14) are formed inside a first housing(10) of a hollow pipe shape. One side of a second housing(20) is coupled with the outlet. A projection is formed on the inner circumference of the other side of the second housing. An opening/closing side(30) is moved between the first housing and the projection by the fluid pressure. A disk(34) and plural discharge holes are formed on the center of the upper side of the opening/closing side. The disk opens and closes the outlet.
    • 目的:提供止回阀,通过在开闭侧面形成一个空间来平稳地排放流体。 构成:在中空管状的第一壳体(10)内形成有入口(12)和出口(14)。 第二壳体(20)的一侧与出口连接。 在第二壳体的另一侧的内周上形成突起。 打开/关闭侧(30)通过流体压力在第一壳体和突起之间移动。 在打开/关闭侧的上侧的中心形成有盘(34)和多个排出孔。 磁盘打开并关闭插座。

    • PURPOSE: A check valve is provided to prevent the deformation of a spring as fluid is not contacted to the spring when an opening and closing valve is vertically opened and closed. CONSTITUTION: A check valve comprises an upper housing(110), a middle housing(150), an opening and closing valve(140), a lower housing(170), and a spring(160). The upper hosing has an inlet(110a) and an outlet hole(110b). The upper inner circumference of the middle housing is thread-coupled to the lower outer circumference of the upper housing. The opening and closing valve is coupled to the interior of the middle housing and is positioned under the upper housing to open and close a fluid passage according to the vertical movement. The upper outer circumference of the lower housing is thread-coupled to the lower inner circumference of the middle housing and has an outlet(170a) through which fluid passing through the opening and closing valve is discharged. The upper end of the spring is inserted in a space between the upper inner wall of the middle housing and the bottom outer circumference of the opening and closing valve. The lower end of the spring is inserted and coupled to a space(171a) between the lower inner wall of the middle housing and the upper end(171) of the lower housing to guide the movement of the opening and closing valve.

    • 目的:提供止回阀,以防止弹簧变形,因为当开关阀处于垂直打开和关闭状态时,流体不会与弹簧接触。 构成:止回阀包括上壳体(110),中间壳体(150),开关阀(140),下壳体(170)和弹簧(160)。 上部软管具有入口(110a)和出口孔(110b)。 中间壳体的上部内圆周线与上壳体的下外周螺纹连接。 打开和关闭阀联接到中间壳体的内部并且定位在上壳体的下方,以根据垂直运动打开和关闭流体通道。 下壳体的上外周线与中间壳体的下内周线螺纹联接,并且具有出口(170a),通过该开关阀的流体被排出。 弹簧的上端插入在中间壳体的上内壁和开闭阀的底部外周之间的空间中。 弹簧的下端插入并联接到中间壳体的下内壁和下壳体的上端(171)之间的空间(171a),以引导开关阀的运动。 (附图标记)(AA)操作中
