充气螺旋闸门

MATERIAL REGULATING GATE VALVE （ GAS-FILLED TYPE ）

充气螺旋闸门是我公司根据气力输送工况需求最新研制的一种调节、切断型闸门，广泛适用于建材、冶金、矿山、轻工、玻璃等行业的气力输送系统。

This valve is the new designed product for adjusting and cutting off on the base of working condition of gas power transportation, which is widely used in the gas power transportation system in building material, glass, mining, light industry and metallurgy industries etc.

结构特点：

Structure characteristic:

充气螺旋闸门采用优质碳钢焊接而成，分上下两个通道，下通道为充气层，上通道为输送物料层，中间为透气层。螺旋型闸板可任意调节闸门开度，特别适用于无粘度的干燥粉料，细微颗粒料等。具有能耗小，无噪音，无污染，少维修，无卡阻，操作方便，使用寿命长等特点。

The valve is welded in fine carbon steel. The lower tunnel of valve is used to aerate, the upper tunnel is used to transport material and the middle layer is breather layer. The gate position can be adjusted by screw slide plate. The valve is suitable for no viscosity powder and small grain etc. it has the features of little energy consumption, no noise, no pollution, little maintenance, no obstruction, convenient operation, long service life etc.

Working principle

物料调节闸门由风机给予低压小容量空气经下通道入气口由充气层充气 ， 气体透过沸腾板均匀向上喷吹 ， 鼓动物料向上位移 ， 物料自重下落时由设备安装斜度而产生位移 ， 不断重复致使物料向前位移 。 调节闸门由丝杆闸板及密封副等组成，由人工转动手轮带动丝杆旋转，使闸门随着螺旋丝杆产生位移，起到任意调节或切断的作用。

The low pressure little volume air supplied by wind machine is aerated from inflation layer through lower tunnel intake. Then the gas blows upwards through boiling plate to drive the material move upwards. Because of the installation incline, material will fall in the effect of gravity. The unceasing repeating actions make the material move forwards. The valve is made up of slide plate and sealing pairs etc. rotate the hand wheel and the screw pole will rotate in the same time to drive the gate move, which has the function of adjusting or cutting off the valve freely.  

使用说明

Usage explanation

•  安装前请检查闸门内腔有无杂物附着，沸腾板受潮没有，如沸腾板受潮请更换后再进行安装，否则影响使用效果。检查各传动部分是否灵活可靠。法兰间连接需加装密封垫片后再均匀拧紧螺栓。

•  调试时，人工转动手轮，顺时针旋转为关，反之为开，运行无卡阻现象即可。

•  Check the valve if there is lumber inside the body or the boiling disc is damp. Exchange the boiling disc before install if it is damp. Otherwise it will affect the operation. Check the transmission part. Add sealed shim between the two flanges and then lock down the bolt equably.

•  Rotate the hand wheel by hand when debug the valve. Clockwise rotate of valve denotes closing, otherwise denotes opening. It will be all right if there is no obstruction.
