Abstract

The invention discloses a pilot control device suitable for a pilot valve. The pilot control device suitable for the pilot valve comprises a pilot valve body and further comprises a valve sleeve assembly arranged in the pilot valve body, a valve rod movably arranged in the valve sleeve assembly and used for controlling a pilot liquid passing cavity to be opened and closed, and a driving device used for providing driving force making the valve rod move and the pilot liquid passing cavity closed for the valve rod, wherein the pilot liquid passing cavity is arranged in the valve sleeve assembly and used for providing oil liquid for a pilot balance cavity in the pilot valve. According to the pilot control device suitable for the pilot valve, by arranging the pilot liquid passing cavity in the valve sleeve assembly to be matched with the pilot balance cavity, fast starting and stopping of the pilot valve is achieved, control is more convenient and faster; and a manual and electromagnetic dual-mode control manner is more convenient, faster and more flexible, the electromagnetic control manner achieves remote control over the opening and closing of the pilot valve, and a safety coefficient is increased.

Description

technical field [0001] The invention belongs to the technical field of hydraulic valves, in particular, the invention relates to a pilot control device suitable for pilot valves. Background technique [0002] In the mechanical industry of hydraulic transmission, such as construction machinery, mining machinery, and agricultural machinery, especially the mine hydraulic support is used as the switch cut-off device for the main liquid supply of a single device, and the plane cut-off valve is often used as the main cut-off valve in the hydraulic system. . This kind of plane globe valve generally adopts a direct-acting spool structure, that is, the rotary handle is generally directly connected to the spool. In this way, by rotating the threaded handle, the valve core rises or falls relative to the valve seat together with the handle, thereby realizing the functions of opening and closing. In the process of coal mining, it is possible to deal with the problem of a single hydraul...
