產(chǎn)品詳情：
工作原理：
物料從上部料斗下落到星形葉片之間，然后隨葉片旋轉(zhuǎn)至旋轉(zhuǎn)閥下部，壓縮空氣從端蓋下部吹入，挾帶落下的物料形成氣固兩相流進(jìn)入氣力輸送管線。
應(yīng)用范圍：
在氣力輸送系統(tǒng)中作為可控加料裝置使用
特別適用于粘附性高、流動(dòng)性差的粉狀物料的氣力輸送
使用條件：
壓力0.15MPa
壓差0.15MPa
120℃
材料：
閥體：鑄304/鑄鋼
轉(zhuǎn)子：SS304/碳鋼
可選結(jié)構(gòu)與附件：
軸裝式減速機(jī)
集氣斗
特點(diǎn)：
▲加大進(jìn)料口設(shè)計(jì)，填充效率高
▲壓縮空氣直接吹掃轉(zhuǎn)子葉片，有效分離粘附在葉片上的物料
▲合理的轉(zhuǎn)子間隙，漏氣少，效率高
▲優(yōu)化設(shè)計(jì)的物料加速通道，壓損小，效率高
▲迷宮吹氣密封，軸端無(wú)漏料
▲軸承外置，壽命長(zhǎng)

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
