Abstract

The invention provides an electromagnetic control remote pilot control valve. The electromagnetic control remote pilot control valve comprises a valve body, an oil return cavity, an oil inlet cavity,a control oil channel and a valve core cavity are formed in the valve body, a valve core mechanism and a ejector rod bush are arranged in the valve core cavity, the ejector rod bush is internally provided with a hollow ejector rod, a damping core is arranged in the hollow ejector rod, a convex block is arranged at the lower part of the damping core, damping springs are arranged on the periphery ofthe damping core, the lower ends of the damping springs are in contact with the damping core, a spring seat is arranged at the lower part of the hollow ejector rod, a through hole is formed in the spring seat, a valve core is arranged in the through hole, the upper end of the valve core extends into the hollow ejector rod to be in contact with the damping core, the middle part of the valve core is provided with a first boss, a second boss is arranged at the lower part of the valve core, an upper u-shaped groove is formed in the side wall of the first boss, a lower u-shaped groove is formed inthe side wall of the second boss, a pressure plate is arranged on the valve body, and a proportional electromagnetic valve is arranged on the pressure plate. The valve has the advantages that the operation performance is excellent, remote control can be realized, the balance of the output of the force of the proportional electromagnetic valve is realized, and the operation is gentle.

Description

technical field [0001] The invention belongs to the technical field of pilot valves, in particular to an electromagnetically controlled remote pilot control valve. Background technique [0002] The pilot valve is an auxiliary valve used to manipulate the control mechanism in other valves or components. At present, the pilot valve is operated by handle control. This kind of handle control has great limitations in remote control. The function of the handle valve is mainly used for remote pilot control. [0003] Therefore, the prior art still needs further improvement and development. Contents of the invention [0004] The object of the present invention is to provide an electromagnetically controlled remote pilot control valve, aiming at solving the limitation of the handle control in the prior art. [0005] The technical solution adopted is: an electromagnetically controlled remote pilot control valve, including a valve body, which is provided with an oil return chamber, ...
