A remote control device for manually operating a hydraulic reversing valve

Abstract

The invention provides a remote control device for manually controlling a hydraulic directional valve. The remote control device comprises a control box, a valve opening device and a valve closing device, wherein the valve opening device and the valve closing device are fixed at two ends of the hydraulic directional valve, and both the valve opening device and the valve closing device comprise an iron core. An electromagnetic coil is orderly wound on the outer surface of each iron core, the electromagnetic coil of the valve opening device and the electromagnetic coil of the valve closing device are serially connected with a change-over switch and then connected onto a control power supply in the control box, a striker linearly reciprocating is arranged in the iron core, and a striking end of the striker corresponds to a valve core of the hydraulic directional valve. The hydraulic directional valve can be remotely and manually controlled in a blast furnace control chamber, technicians are helped to rapidly find out failure causes while the furnace top valve can be normally opened and closed, normal running of equipment is restored, smooth distribution of a blast furnace is guaranteed, the production cost of the blast furnace is reduced, and economic benefits are created for enterprises.

Description

technical field [0001] The invention relates to a remote control device for manually operating a hydraulic reversing valve. Background technique [0002] The valve equipment on the top of the furnace is very critical in the ironmaking process of the blast furnace. The switching action of the valves on the top of the furnace is mainly driven by the hydraulic system on the top of the furnace. . During the production process of the blast furnace, the valves on the top of the furnace operate frequently and in an orderly manner, among which the hydraulic valve table and hydraulic reversing valve play a key role. However, in actual production, sometimes due to the loss of automation control signal, hydraulic transmission failure, mechanical structure failure and other reasons, the furnace top valve cannot operate normally, and the furnace top cannot be fed and distributed, and the blast furnace can be reduced or even shut down in a short period of time. , which affects the condi...
