The invention discloses a different-pressure automatic shuttle valve, comprising valve body, through end cover, valve core ball, spring seat, spring, inlet end, outlet port. Cavity, which comprises large-diameter part and small-diameter part, is set in the valve body. The spring, of which one end is connected with outlet port and the other end is connected with spring seat, is set in the small-diameter part of cavity. The valve core ball on the spring seat is set in the large-diameter of cavity. Inlet and outlet ends are located at two ends of valve body.
本发明公开了一种压差式自动关闭阀，该阀包括阀体、通端盖、阀芯球、弹簧座、弹簧、进口端、出口端；阀体内部开有腔体，包括大径部分与小径部分；腔体小径部分安装有一端与出口端连接，另一端与弹簧座连接的弹簧；腔体大径部分有安装在弹簧座上的阀芯球；进口端与出口端分别位于阀体的两端。
When the pressure is low, the role of Poppet head pressure sufficient to overcome the pressure regulator spring force, Poppet Head is closed at this time there is no pressure on the oil through the damping holes on the balance of the piston movement, so a balance piston, the next two cavity pressure equal, balanced piston under the action of the spring force gently on the top of the seat, pressure port and overflow port unreasonable.
当压力较低时，作用在提动头上的压力不足以克服调压弹簧力，提动头处于关闭状态，此时没有压力油通过平衡活塞上的阻尼孔流动，故平衡活塞上、下两腔压力相等，平衡活塞在弹簧力的作用下轻轻地顶在阀座上，压力口和溢流口不通。
The utility model discloses a magnetic lift device which comprises a main magnetic lift part, a rotating pole bracket, a transmission supporting saddle, a left rotating pole and a right rotating pole. A turning plate yoke device is arranged on the upper surface of the main magnetic lift part, and the turning plate yoke comprises a yoke head, a yoke head base, a constringent spring, a pulling rope as well as a rope sling. The yoke head is arranged slidingly in the hollow cavity of the yoke head base, and the constringent spring is arranged at one end inside the yoke head. One end of the pulling rope is fixedly connected with the inner end of the yoke head, while the other end is fixedly connected with the rotating pole.
