The most of the flue gas pipelines for conveying the dust are plug-in type valves, and the characteristics of the plug-in type valves are explained.
In actual production practice, particularly, the conveying of flue gas with dust is troubled by production managers and engineering technicians due to the fact that the production environment is severe, many faults exist, the maintenance is difficult, and the maintenance is difficult.
In the process of conveying the dust and the smoke, the dust is easy to accumulate and deposit on the pipe wall, the valve blade, the valve plate and the baffle.
Due to dust deposition and adhesion, the following phenomena are extremely likely to occur: the inserting plate groove is easy to block and difficult to open and close back and forth; the pipe wall of the spile rabbet is dusted, so that the valve cannot be tightly closed; the ash deposition of the inserting plate causes the reciprocating opening and closing resistance of the inserting plate to be large and the operation to be difficult; the valve has the disadvantages of multiple faults, easy damage, difficult maintenance, multiple replacement frequency, high cost and easy production stop.
If the electric control system is selected to control the opening and closing of the valve in the process, the electric control system is easy to break down, even the electric control component is overloaded and burnt, so that the valve is ineffective, and the production is easy to stop.
In addition to the above-described disadvantages, the process valve has the disadvantages of difficult maintenance, high cost, easy failure, environmental protection, safety accident, production stoppage and various direct and indirect economic losses.
