矿用风筒分流器规格

矿用风筒分流器，该风筒分流器包括弧形插板、扇页闭合器、锁紧装置，扇页闭合器通过连接件连接在风筒的一侧，弧形插板通过锁紧装置与扇页闭合器连接，扇页闭合器连接有滑块，滑块来回滑动于弧形插板上设置的滑道内，使用该风筒分流器，既可以减少工人的劳动强度，又避免了过去拆接风筒时需要停风，给作业人员带来的安全隐患，进一步改善了井下工作环境。

一、矿用风筒分流器规格用途：用于煤矿、隧道、井下局部扇风机进行正压通风；

二、风筒结构及规格尺寸 风筒品种：风筒按涂覆布材料分为橡胶涂覆布正压风筒、塑料涂覆布正压风筒和橡塑涂覆布正压风筒。

矿用风筒分流器规格The present invention relates to a mine ventilation duct shunt, the shunt duct includes an arcuate flapper, fan page is closed, a locking device, fan pages closure via a connecting member on one side of the hairdryer, curved plug board through the locking device connected to the fan page is closed, fan pages closure connected to the slider, the slider slides back and forth in the slide set on the arc-shaped card, use the duct splitter, not only can reduce the labor intensity , but also to avoid the past disconnect duct need to stop the wind, giving workers the potential safety problems, to further improve the underground working environment.

矿用风筒分流风筒耐风压性：风筒经耐风压试验后不得产生风筒脱节、涂覆布撕裂、接缝开口等现象。风筒直径膨胀率不得大于3.0%. 1、耐风压测定：使风筒内压达到5000～5100Pa，并保持5min，观察风筒有无脱节、撕裂、接缝开口等异常现象； 2、膨胀率测定：在风筒耐风压测定的同时，用卷尺测量风筒周长，计算风筒直径膨胀率。
