Steam valve opening and closing control system, steam valve opening and closing control method and tobacco processing equipment

Abstract

The invention relates to a steam valve opening and closing control system, a steam valve opening and closing control method and tobacco processing equipment, wherein the control system comprises a steam valve (4) and a pneumatic control branch; a reversing valve (3) is arranged on the pneumatic control branch; when the reversing valve (3) is switched to the first state, compressed air is introduced through the pneumatic control branch so as to open the steam valve (4); when the reversing valve (3) is switched to the second state, ordinary pressure air is introduced through the pneumatic control branch so as to close the steam valve (4). Through the control system, the opening and the closing of the steam valve can be more convenient and faster; the operation difficulty of persons can be reduced; the reliability and the safety of the steam valve opening and closing can also be improved; in addition, the opening and closing in-place degree of the steam valve has specific standards; afterthe closing, the steam supply can be completely cut off, so that the service life of the valve is prolonged; the energy source waste is reduced.

Description

technical field [0001] The invention relates to the technical field of tobacco processing equipment, in particular to a steam valve opening and closing control system and method, and tobacco processing equipment. Background technique [0002] In the tobacco industry, especially silk production, most of them do not need continuous production throughout the day, and the equipment needs to be shut down for cleaning and maintenance every day, every week, every month, or even every year. When shutting down, the main steam valve on each tobacco processing equipment must be closed, so the valve opening and closing operations are frequent. [0003] In the prior art, the steam valve is usually manually opened and closed, which is laborious to operate, and the standard of closing is not in place, and the strength of the operator is different. These factors will make the steam valve unable to completely cut off the steam supply after the steam valve is closed, reducing the service life...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the steam valve is usually manually opened and closed, which is laborious to operate, and the standard of closing is not in place, and the strength of the operator is different. These factors will make the steam valve unable to completely cut off the steam supply after the steam valve is closed, reducing the service life of the valve, causing Energy waste

Moreover, the opening process of the main steam valve should be slow to avoid water hammer, which requires operators to have sufficient experience, negligence will cause personal injury and equipment damage, and there are potential risks
