Adjust the pneumatic valve solutions often get stuck or jams

(
An external gas or steam to wash using ordinary regulating pneumatic valve, some easy to precipitate, medium containing solid particles often cause congestion in throttling mouth, guide, can open the pneumatic valve cover bottom plug, external flushing gas or steam pipeline.
When blocked or jammed, open external pneumatic valve, gas or steam can be completed in fixed adjustment under the condition of pneumatic valve flushing work, make the normal operation of pneumatic valve.

Breaking-out pneumatic valve and clean welding slag, rust, pipeline'll stay under the throttle mouth, guiding parts, pneumatic valve cover balance hole blocked or jammed, pneumatic valve core surface, guide surface strain and scratches, seal surface indentation, etc.
This kind of phenomenon often occurred in early starts during and after overhaul was put into operation, is the most common fault.
Encounter this situation, must remove the pneumatic valve and clean, remove the slag content, such as sealing surface grinding damage should also, at the same time open the bottom cover, to rinse away from balance hole fall into the pneumatic valve under the residue inside the cover, and the pipeline to wash.
Before put into operation, to adjust the pneumatic valve fully open, the medium flows into normal operation again after a period of time.

To switch to other forms of regulating pneumatic valve such as the straight single, two-seater pneumatic valve into the sleeve pneumatic valve, pneumatic valve Angle, etc.
Single and double pneumatic valve throttling area and circular distribution, small gap, easy jam stuck;
Sleeve pneumatic valve throttling area of concentration distribution, for the window, big gap, slag content easily;
Through pneumatic valve is an inverted s-shape flow, upper and lower chamber should dead zone, provides the medium precipitation;
Angle of pneumatic valve is an inverted l-shaped flow, medium is like.
Elbow, self-cleaning performance is good, not easy sedimentation jam.
(
Pipeline strainer installed on the regulation of small diameter pneumatic valve, especially the small flow control, pneumatic valve, the throttle gap is very small, medium there must be no residue at all.
In this jam, the best line in front of the pneumatic valve installation of a strainer, to ensure that the media to go through.
