The invention discloses a program-controlled double-plate constant pressure / constant flow valve, which comprises a valve body shell, a fixed valve plate and a movable valve plate, and is characterized in that the valve body shell is cylindrical, wherein both the fixed valve plate and a bearing bracket are fixedly arranged in the valve body shell; one end of a transmission shaft is supported against the fixed valve plate, and the other end of the transmission shaft is supported against the bearing bracket; a movable valve and a transmission gear are arranged on the transmission shaft; the outer surface of the valve body shell is fixedly provided with an electro-hydraulic push rod supporting frame; an electro-hydraulic push rod device is arranged on the electro-hydraulic push rod supporting frame; one end of a transmission rack is engaged with the transmission gear, and the other end of the transmission rack is connected with a motion output end of the electro-hydraulic push rod device; and a signal receiving device in the electro-hydraulic push rod device is connected with a signal probe through a signal line. The program-controlled double-plate constant pressure / constant flow valve can be widely applied to ventilation and dust removal pipelines in industries such as metallurgy, chemical industry, building materials and mines, the problem of air balance of a ventilation and dust removal system can be substantially solved, the application performance of a fan is improved, the ventilation and dust removal effect is improved, and the dust catching rate of the dust removal system is improved.
Description
technical field [0001] The invention relates to a control valve, which is applied to the air volume balance control of ventilation and dust removal systems in industries such as metallurgy, building materials, and mines. Background technique [0002] At present, the equipment used in the ventilation and dust removal industry for the air volume control of the multi-point ventilation and dust removal system is generally an electric butterfly valve, and sometimes a manual flapper valve is connected in series. With such a process configuration, manual operation is very difficult, especially for large-diameter flapper valves, and the adjustment performance of the electric butterfly valve itself is very poor. Therefore, it is difficult to balance the air volume of the entire ventilation and dust removal system. Control, affecting the ventilation and dust removal effect of the whole system. Contents of the invention [0003] The purpose of the patented technology of the present ...
