礦用風(fēng)筒分流器規(guī)格

礦用風(fēng)筒分流器，該風(fēng)筒分流器包括弧形插板、扇頁閉合器、鎖緊裝置，扇頁閉合器通過連接件連接在風(fēng)筒的一側(cè)，弧形插板通過鎖緊裝置與扇頁閉合器連接，扇頁閉合器連接有滑塊，滑塊來回滑動于弧形插板上設(shè)置的滑道內(nèi)，使用該風(fēng)筒分流器，既可以減少工人的勞動強度，又避免了過去拆接風(fēng)筒時需要停風(fēng)，給作業(yè)人員帶來的安全隱患，進一步改善了井下工作環(huán)境。

一、礦用風(fēng)筒分流器規(guī)格用途：用于煤礦、隧道、井下局部扇風(fēng)機進行正壓通風(fēng)；

二、風(fēng)筒結(jié)構(gòu)及規(guī)格尺寸 風(fēng)筒品種：風(fēng)筒按涂覆布材料分為橡膠涂覆布正壓風(fēng)筒、塑料涂覆布正壓風(fēng)筒和橡塑涂覆布正壓風(fēng)筒。

礦用風(fēng)筒分流器規(guī)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.

礦用風(fēng)筒分流風(fēng)筒耐風(fēng)壓性：風(fēng)筒經(jīng)耐風(fēng)壓試驗后不得產(chǎn)生風(fēng)筒脫節(jié)、涂覆布撕裂、接縫開口等現(xiàn)象。風(fēng)筒直徑膨脹率不得大于3.0%. 1、耐風(fēng)壓測定：使風(fēng)筒內(nèi)壓達到5000～5100Pa，并保持5min，觀察風(fēng)筒有無脫節(jié)、撕裂、接縫開口等異?，F(xiàn)象； 2、膨脹率測定：在風(fēng)筒耐風(fēng)壓測定的同時，用卷尺測量風(fēng)筒周長，計算風(fēng)筒直徑膨脹率。
