What problems should be paid attention to in the selection of star type ash discharge valve? Today, Tianlan environmental protection editor tells us:

1. When selecting the star type ash discharge valve, the output of the star type ash discharge valve should be determined first, and the appropriate diameter of the star type ash discharge valve should be selected according to the output. The diameter of normal star type ash discharge valve is round or square at the top and bottom. When it is not customized, it can be made into upper circle, lower circle, upper circle and lower circle.

2. When determining the basic model of the star type ash discharge valve, we need to pay attention to whether the working environment of the star type ash discharge valve has positive pressure or negative pressure. When there is wind pressure, the star type ash discharge valve must be air lock type. Generally, there is mechanical air lock, that is, the star type ash discharge valve and the valve body are mechanically finished. After finishing, the gap is small. When working, the material fills the gap to achieve the purpose of air lock . In addition, there is flexible air lock. According to different materials, wear-resistant canvas belt and thin stainless steel sheet can be selected and fixed on the impeller flange, 5-10mm beyond the flange. During the rotation process, the gap between the flange and the valve body can be blocked by the deformation of stainless steel sheet.

3. After the basic shape of the star type ash discharge valve is determined, whether the frequency conversion speed regulation is needed can be determined according to the specific feeding range. If the frequency conversion speed regulation is needed, the driving motor of the star type ash discharge valve can be selected as the frequency conversion motor, and the frequency converter is equipped to micro control the feeding amount in the later stage. The normal speed of star type ash discharge valve is generally between 24-43 rpm. When the feeding amount is very small, the two-stage motor can be selected to reduce the speed and adjust the feeding.
