Off-tracking corrector valve

Abstract

The invention relates to the technical field of papermaking machine dry net off-tracking correcting equipment, and provides an off-tracking corrector valve. The off-tracking corrector valve comprises a corrector valve body and a detection baffle, the corrector valve body comprises a corrector valve housing, the corrector valve housing is provided with valve housing air inlet holes, the left and right sides inside the corrector valve housing are provided with valve housing air guide holes communicated with the valve housing air inlet holes, the corrector valve housing is internally rotationally provided with a corrector valve shaft, the left and right sides of the corrector valve shaft are provided with valve shaft air inlet holes, the two ends of the corrector valve shaft are both provided with valve shaft air outlet holes communicated with the corresponding valve shaft air inlet holes, and the detection baffle is fixedly connected to the middle of the corrector valve shaft through a connecting rod, and performs front-rear oscillation in the axial direction of the corrector valve shaft. The off-tracking corrector valve is controlled by a rotation type air channel, the air pressure stability is good, the detection reaction sensitivity is high, detects papermaking machine dry net at high-speed running in real time, compression air is quickly and accurately output and adjusted, and the pneumatic correcting mechanism can timely and accurately corrects a dry net.

Description

technical field [0001] The invention belongs to the technical field of deviation correcting equipment for a dry net of a paper machine, and in particular relates to a deviation corrector valve. Background technique [0002] In recent years, with the rapid development of the paper industry and the continuous growth of output, the operating speed of the paper machine has also been continuously improved, and higher requirements have been put forward for the deviation corrector of the dry web, including detection response sensitivity and Adjust the movement sensitivity to ensure that the dryer rollers run at high speed without stopping the paper and the wire, so as to ensure the normal operation of the paper machine. [0003] Most of the corrector valves of the current correctors use forward and backward moving valve shafts. When the dry net deviates, the valve shaft moves forward or backward to control the air pressure of the pneumatic correction mechanism, thereby controlling ...

AI Technical Summary

Problems solved by technology

[0003] Most of the corrector valves of the current correctors use forward and backward moving valve shafts. When the dry net deviates, the valve shaft moves forward or backward to control the air pressure of the pneumatic correction mechanism, thereby controlling the pneumatic correction mechanism. To adjust the dryer web, this kind of corrector valve has poor air pressure stability and low detection response sensitivity, which will also affect the adjustment movement sensitivity of the pneumatic correction mechanism. For the dryer web running at high speed, it is very easy to cause paper breakage and wire breakage Occurs, it is difficult to meet the needs of high-speed operation of the paper machine
