Single core adjustable shrinkage hole

The plug-in single core adjustable shrinkage hole is mainly 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; According to the imperial system, there are 8 types of specifications, including 18 ", 20", 22 ", 24", 26 ", 28", 30 ", and 32", totaling 17 specifications. According to the degree of wear, the plug-in single core adjustable shrinkage hole is divided into two types: ordinary type and wear-resistant type.

1、 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

2、 When ordering a plug-in single core adjustable shrinkage hole, the following parameters should be provided:

Maximum working pressure (P): Pa;
