Valve controlled protection system with high reliability and long-running sexual

Axial fan to blast valve as research object, the check valve controlled protection system , aimed at the check valve itself does not affect the work of the case , in the blast when the normal flow of ventilation ducts , improve valve valves, reducing valve head loss , improve blast furnace steel production . Valve controlled  2 way manifold  parts protection system using electromagnets and three-phase AC motor as the driving force to enhance the valves, electric control part adopts PLC as the main control device to control the movement of the mechanical structure ;  Instrument manifold  ​​redundant monitoring module , to improve the system reliability ; prepared using the graphical programming software remote monitoring program to facilitate the operator to operate the control system and view historical data ; serial communication and the use of CAN bus technology to connect PLC  Instrument valve manifold , redundant monitoring module and a remote monitoring system. Valve controlled protection system with high reliability and long-running nature , and has expansion capability. The greatest feature of this system is the mechanical moving parts with our own security, which can be electrically controlled in the case of partial failure of the check valve can still ensure the work ; Meanwhile , PLC and redundant monitoring module via two communication systems simultaneously, improving reliability ; preparation RMON program good user interface , making the system easier for the operator to accept.
