RVB-直吹式粉料旋转阀

产品详情：

工作原理：

物料从上部料斗下落到星形叶片之间，然后随叶片旋转至旋转阀下部，压缩空气从端盖下部吹入，挟带落下的物料形成气固两相流进入气力输送管线。

应用范围：

在气力输送系统中作为可控加料装置使用

特别适用于粘附性高、流动性差的粉状物料的气力输送

使用条件：

压力0.15MPa

压差0.15MPa

120℃

材料：

阀体：铸304/铸钢

转子：SS304/碳钢

可选结构与附件：

轴装式减速机

集气斗

特点：

▲加大进料口设计，填充效率高

▲压缩空气直接吹扫转子叶片，有效分离粘附在叶片上的物料

▲合理的转子间隙，漏气少，效率高

▲优化设计的物料加速通道，压损小，效率高

▲迷宫吹气密封，轴端无漏料

▲轴承外置，寿命长

Product details:

working principle:

The material falls from the upper hopper into the space between the star shaped blades, and then rotates with the blades to the lower part of the rotary valve. Compressed air is blown in from the lower part of the end cover, carrying the falling material to form a gas-solid two-phase flow and entering the pneumatic conveying pipeline.

Application scope:

Used as a controllable feeding device in pneumatic conveying systems

Especially suitable for pneumatic conveying of powdery materials with high adhesion and poor flowability

Usage conditions:

Maximum pressure 0.15MPa

Maximum pressure difference of 0.15MPa

Maximum 120 ℃

Material Science:

Valve body: cast 304/cast steel

Rotor: SS304/carbon steel

Optional structures and attachments:

Shaft mounted reducer

Gas collection hopper

characteristic:

▲ Increase the design of the feed inlet for high filling efficiency

Compressed air directly blows the rotor blades, effectively separating materials adhered to the blades

▲ Reasonable rotor clearance, minimal air leakage, high efficiency

Optimized material acceleration channel with low pressure loss and high efficiency

▲ Maze blowing seal, no leakage at the shaft end

▲ External bearing, long service life
