Hydraulic oil suction self-sealing device
The invention discloses a hydraulic oil suction self-sealing device. The hydraulic oil suction self-sealing device comprises a limiting screw, an ejector rod fixing plate, an elastic element, an ejector rod, a sealing plate and a valve seat; the limiting screw is arranged at the end, away from the elastic element, of the ejector rod, and used for achieving movement of the ejector rod; the ejectorrod sequentially penetrates through the ejector rod fixing plate, the sealing plate and the valve seat, and the sealing plate is fixedly connected with the ejector rod; the elastic element is locatedbetween the ejector rod fixing plate and the sealing plate and is arranged on the ejector rod in a sleeving manner; an oil port 61 is formed in the valve seat in the axial direction; and the sealing plate 5 completely covers the oil port 61 when being in contact with the valve seat 6. The hydraulic oil suction self-sealing device aims at solving the problems that a butterfly valve is complex in structure and high in manufacturing cost.
本发明公开了一种液压吸油自封装置，包括限位螺杆、顶杆固定板、弹性元件、顶杆、封板和阀座；限位螺杆设于顶杆远离弹性元件的一端，用于实现顶杆的移动；顶杆依次穿设于顶杆固定板、封板和阀座，封板与顶杆固定连接；弹性元件位于顶杆固定板、封板之间且弹性元件套设于顶杆，阀座沿轴向开设油口61，封板5与阀座6接触时完全覆盖油口61。该液压吸油自封装置的目的是解决蝶阀结构复杂、制造成本高的问题。
