The present invention relates to the field of blast furnace front control auxiliary technology, in particular to a control system for switching valve tables, comprising: a pressure oil pipeline through which the pressure oil selects the oil circuit through a valve table selection block, and The pressure oil is delivered to the first valve table or the second valve table; the valve table selection block, the valve table selection block includes a first electromagnetic reversing valve and a second electromagnetic reversing valve, and the first electromagnetic reversing valve and the second electromagnetic reversing valve The second valve table is connected, the second electromagnetic reversing valve is connected with the first valve table; the second ball valve and the fifth ball valve, the first valve table is directly connected with the pressure oil pipeline through the second ball valve, so The second valve table is directly connected to the pressure oil pipeline through the fifth ball valve. The control system and control method for valve table switching of the present invention effectively solve the problem in the prior art that when one valve table of the double valve table fails, switching to the other valve table is not timely, which is likely to cause safety hazards.
Description
A control system and control method for valve table switching technical field The present invention relates to blast furnace front control auxiliary technical field, relate in particular to a kind of control system for valve table switching and control methods. Background technique The valve table is an important part of the hydraulic system in front of the blast furnace, and it is controlled by a series of hydraulic valve groups, using It is used to realize the action of equipment such as opening machine and mud gun, so as to realize the opening and blocking of molten iron. Usually in the hydraulic system, the valve table is composed of control elements, and in actual production, there will be two valve tables that are mutually Standby situation, to prevent damage to one of the valve tables to avoid production safety and stability, when the system is working, the ball valve is in a constant state. In the open state, both valve tables have power sources and have th...
