| description | The utility model discloses a universal calibration cover for fixed gas alarm detection, which comprises a calibration cover body, the body is provided with a detection port, an air inlet and an air outlet, the detection port is step-shaped from outside to inside, and the caliber of the detection port is gradually reduced. When the calibration cover is used, various detection heads with differentsizes can be matched with the detection port, and detection of most of gas alarms can be realized through one calibration cover, so that the equipment carrying amount is reduced, and the time for looking for a proper calibration cover is also saved.
本实用新型公开了一种固定式气体报警器检测通用校准罩，包括校准罩本体，所述本体上设置有检测口、进气孔和出气孔，所述检测口自外向内呈台阶状且口径逐渐缩小。该种校准罩在使用时能够将各种不同尺寸的检测头与检测口配合，通过一个校准罩能够实现大部分气体报警器的检测，从而减少了设备携带量，也节省了为了寻找合适校准罩的时间。 |
