Description

Technical Field

[0001] The invention relates to the technical field of valves, in particular to an electronic-grade powder resting angle valve and an assembly process thereof. Background Art

[0002] The valve core of the angle of repose valve is installed in the inner cavity of the valve body in a rotational manner around the axis of the valve stem. The valve body includes an upper valve body with an inlet conduit installed and a lower valve body with an outlet conduit installed. The angle of repose valve is used in the powder conveying pipeline. With the help of the angle of repose characteristics of the powder, the valve core blocks the feed port of the valve body through the rotation of the valve stem. In this operation process, the side scouring of the valve core by the powder changes to the front scouring. The powder accumulates in the valve core and blocks the feed port of the valve body, realizing the cutting off of the powder conveying.

[0003] Most of the traditional repose angle valve cores are non-replaceable or difficult to replace. Long-term use will cause erosion and wear, which will directly lead to scrapping. Traditional ones either have no guide pipe or guide plate at the outlet, or the local wear of the overall setting of the guide pipe will directly lead to the replacement of the entire thing, which will invisibly increase the service life.
