Split type adjustable shrinkage hole

1、 Overview:
The split type dual core adjustable shrinkage hole is used to adjust the resistance of the primary air duct on the powder feeding pipeline, so that the primary air velocity at the inlet of each powder feeding pipeline at the burner remains consistent. The specifications are formulated as follows: DN200-DN600, a total of 9 types; The specifications are formulated in English as follows: 18 ", 20", 22 ", 24", 26 ", 28", 30 ", and 32", totaling 17 specifications. According to the degree of wear, the split type dual core adjustable shrinkage hole is divided into two types: ordinary type and wear-resistant type.

2、 Main technical parameters:

The adjustment range is 30% to 100% of the cross-sectional area of the pipeline.

Working temperature: ≤ 350;

Connection methods: direct welding and flange type
