My company in the production of "wearable valve on the many years of anti-fouling cast valve were studied: the existence of a slurry transfer pipe wear and fouling so radically opposite two problems, relatively speaking, to solve wear problem than solving the scaling problem is easier, it is important fittings have sufficient hardness and wear resistance, there is not a high cost is feasible, but scaling problem is more complicated, we have to use surface water and oil affinity weak , by strong polymer material lining in a steel tube test tube in power plant ash fouling, dirt will not end up with, but soon it will be worn this material is gone, exposing the steel pipe, steel pipe inner surface and very fast knot of scale. This is because any wear and fouling soybean oil slurry duality, the particle size of the slurry is composed of media, it will be on the inner surface of the pipe corrosion flow, simultaneously by different chemical composition and physical properties of another possible scaling upper half of the pipe wall Qinghe power plant ash fouling, the lower part of the wear is an example. So entirely without fouling the material can be resolved to solve the knot material fouling problem, but not solve the problem of wear at the same time , in theory if they can find a rate equal to the scale of wear, the material is the critical point is the most ideal, but in fact with the change of the chemical composition and physical properties of the slurry, the critical point from the change, We have varied without changing the material slurry, so far no one can fundamentally solve the problem of scaling, based on the fact that we changed the direction of the development of an anti-fouling type cast stone wear ball in the world. No a malfunction and damage, and even a seal none replacement method is to add a two-way sealing of cast stone wear ball valve body inlet port and an outlet flushing sewage outfall, catchy take pressure pipes, under the mouth then scum, according valve control in valve opening and closing during the slurry flow path ends with the ball into the valve body when the valve is fully open or fully closed, front runner in between the body due to the self close action means completely cut off, then open the valve of import and export with water flush valve chamber, so they can not clear the ash deposition statement, each valve open or close a valve in turn are washed again, thus ensuring that the valve operation Flexible order to solve the junction flow channel before and after fouling the problem, an exemption from the erosion of the tedious, we have developed an intelligent automatic flush, anti-fouling ball. anti-fouling main cast stone ball wear Performance specifications nominal diameter DN (mm) 80-1200 Nominal pressure PN (Mpa) 1.0-20.0 for the media mud. ash slurry Crude oil water steam - such as the use temperature ℃ -40-120. -40-250 drive way manual electric pneumatic Scroll Ball wear anti-fouling cast stone main component material Nominal diameter DN (mm) material body.
