Abstract

一种多向通风控制阀,属于隧道工程技术领域,其特征是:在三通或四通的出风管上开有两个通孔,两个通孔直线对应在出风管的中心线上,通孔外固定有钢套,转轴与圆形叶板固定,圆形叶板直径小于出风管直径,转轴穿过两个带钢套的通孔,并与出风管转动配合。有益效果是:易于选材、制作简单、操作方便,通过设置通风控制阀,对风向进行控制,改善了通风排烟效果,方便了施工,节约了工程成本,加快了施工进度。

Description

多向通风控制阀技术领域
[0001] 本实用新型属于隧道工程技术领域。 背景技术
[0002] 目前,在长大隧道施工过程中,经常需要通过斜井的方式增加工作面以增加施工 速度,因斜井的存在使得进入到两个或者更多个工作面的气流很小,致使隧道在施工时通 风排烟不畅,排烟效果不理想,工作效率低。发明内容
[0003] 本实用新型的目的是:提供一种多向通风控制阀,它专用在隧道施工过程中,高效 率地通风排烟。
[0004] 本实用新型的技术方案是:在三通或四通的出风管上开有两个通孔,两个通孔直 线对应在出风管的中心线上,通孔外固定有钢套,转轴与圆形叶板固定,圆形叶板直径小于 出风管直径,转轴穿过两个带钢套的通孔,并与出风管转动配合。
[0005] 本实用新型的有益效果是:易于选材、制作简单、操作方便,通过设置通风控制阀, 对风向进行控制,改善了通风排烟效果,方便了施工,节约了工程成本,加快了施工进度。附图说明
[0006] 图1是本实用新型通孔位置主视图;
[0007] 图2是本实用新型立体简视图。具体实施方式
[0008] 下面结合附图对本实用新型做进一步描述:
[0009] 如图所示,1是通孔、2是钢套、3是圆形叶板、4是转轴。
[0010] 首先在在三通或四通的出风管上开有两个通孔1,通孔1的大小以能使转轴4穿过 为宜,在通孔1外围焊接固定上管型钢套2,使通孔1在转轴4在穿过使用时不致毁坏,再将 圆形叶板3放入出风管内,并与转轴4固定,转轴4要直穿圆形叶板3中心点,在转轴4外 端可加固一个旋转把手,使其便于转动,随着叶板在出风管内的转动,即可调节出风管出风 的大小,使排烟管道得到更有效地利用。
