Fire-fighting automatic pressure relieving device

消防自动泄压装置

Abstract

The utility model discloses a fire-fighting automatic pressure relieving device which mainly comprises a fixed frame, a cover plate and a pressure adjusting device, wherein the cover plate is connected with the upper part of the fixed frame by a hinge; and the pressure adjusting device is arranged at the connecting position of the bottom part of the fixed frame and the cover plate. Due to the fire-fighting automatic pressure relieving device, the opening and the closing are realized by rotation of a U-type bearing plate of the cover plate around a hinge fixed on the fixed frame. The fire-fighting automatic pressure relieving device is provided with the pressure adjusting device which consists of an adjustable ball latch seat and an adjustable ball latch plug. The adjustable ball latch seat is arranged on the fixed frame, and the adjustable ball latch plug is arranged on the cover plate. By adjusting a set screw on the adjustable ball latch seat, a spring is compressed and the control of clamping force to the adjustable ball latch plug is realized, thus reaching the set opening pressure value of a protective area.
本实用新型公开了一种消防自动泄压装置,主要包括固定架、盖板和压力调节装置,盖板通过铰链连接在固定架的上部,压力调节装置设置在固定架底部与盖板的相接处。由于本实用新型消防自动泄压装置,开启和关闭是通过盖板的U型支承板,绕固定在固定架上的铰链旋转来实现的。该实用新型消防自动泄压装置安装了压力调节装置,压力调节装置由可调滚珠碰锁座和可调滚珠碰锁插销组成。可调滚珠碰锁座安装在固定架上,而可调滚珠碰锁插销设置在盖板上。通过调节可调滚珠碰锁座上的紧定螺钉,使弹簧压缩,实现对可调滚珠碰锁插销的夹紧力大小控制,从而达到防护区的设定开启压强值。
