Abstract

The invention discloses a pilot controller. The pilot controller comprises a pilot valve body, a main valve body and a main valve spool which is arranged in a pilot balancing cavity of the main valve body. The pilot controller further comprises a first valve sleeve module and a second valve sleeve module which are arranged in the pilot valve body, a valve rod which is movably arranged in the first valve sleeve module and the second valve sleeve module and used for controlling the opening and closing of a pilot liquid passing cavity, and a driving device used for providing driving force for the valve rod to drive the valve rod to move and open and close the pilot liquid passing cavity. The pilot liquid passing cavity is arranged in the first valve sleeve module and used for providing oil liquid for the pilot balancing cavity. According to the pilot controller, the pilot controlling balancing cavity structure which is capable of bearing a working pressure of 50-80MPA is utilized, so that the working scope of a stop valve can be greatly improved, the rapid opening and closing can be realized and the controlling can be more convenient; a manual and electromagnetic dual-mode control mode is more convenient and more flexible, the remote control of the opening and closing of the pilot controller can be realized by the electromagnetic control mode and the safety factor can be improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic valves, and in particular, the invention relates to a pilot controller. Background technique [0002] In the hydraulic transmission machinery industry, such as construction machinery, mining machinery, and agricultural machinery, especially the mine hydraulic support is used as the switch and cut-off device for the main liquid supply of a single equipment, and the plane cut-off valve is mostly used as the total cut-off valve in the hydraulic system. . This kind of plane globe valve generally adopts a direct-acting valve core structure, that is, the rotary handle and the valve core are generally directly connected together. In this way, by rotating the threaded handle, the valve core is raised or lowered relative to the valve seat together with the handle, thereby realizing the functions of opening and closing. The single hydraulic support can be dealt with during the coal mining process. [0...
