The invention relates to a control valve, in particular to a vacuum crane control valve, and solves the problems of resilience and instability of a vacuum control valve. Comprising a valve body, the upper portion of the valve body is an upper connector connected with a vacuum telescopic pipe, the lower portion of the valve body is a lower connector connected with a suction cup, a through valve cavity is formed in the portion, between the upper connector and the lower connector, of the valve body, the valve cavity is arranged in the axial direction of the valve body, and a rotating handle is arranged on the side face of one radial side of the valve body. A rotary intercepting piece is arranged on the side wall of the other side, opposite to the rotary handle, of the valve body, a linkage shaft is connected between the rotary intercepting piece and the rotary handle, the traditional constraint that springback is prone to happening, and an operation target is not clear is broken through, the linkage shaft is adopted for driving angle control of a mechanical turning plate and the rotary intercepting piece, and therefore the mechanical turning plate and the rotary intercepting piece are combined. Under the conditions of a simple and stable mechanical principle and angle control, an operation target is clear, and a good stability effect is achieved.
本发明涉及一种控制阀,特别涉及一种真空吊控制阀,解决了真空控制阀的回弹、不稳的问题。包括阀体,所述阀体上部为与真空伸缩管连接的上接口,所述阀体下部为与吸盘连接的下接口,所述阀体在上接口与下接口之间设有贯通的阀腔,所述阀腔沿阀体轴向设置,所述阀体在径向一侧侧面设有旋转手柄,且阀体在相对旋转手柄的另一侧侧壁上设有旋转截流片,所述旋转截流片与旋转手柄之间连接有联动轴,突破传统易回弹、操作目标不清晰的束缚,采用联动轴带动“机械翻板”结合“旋转截流片”的角度控制,在较简单稳定的机械原理及角度控制条件下,使操作目标明确,且有很好的稳定性效果。
