标准响应干式喷头采用 5mm 直径玻璃泡，快速响应喷头采用 3mm 直径玻璃泡，分为直立式、下垂式和隐蔽
式三类，干式喷头使用的典型场所是 :
■ 干式系统需要使用下垂式喷头的场所。
■ 湿式系统中喷头和其接管可能暴露在非采暖区域的场所，
■ 消防系统需要季节性停用，管网必须排水防冻的场所 ( 如旅游和休养胜地建筑物冬季不营业，消防系统为了防冻，管网必须排水 )。
The standard response dry nozzle uses 5mm diameter glass bubbles, while the quick response nozzle uses 3mm diameter glass bubbles, which are divided into three types: upright,hanging, and concealed. The typical places where dry nozzles are used are:
■ Where the drysystem requires the use ofpendant sprinklers.
■ In wet systems, sprinklers and their nozzles may be exposed to non-heatec areas.
■ Places where the fire protection system needs to be stopped seasonallyand the pipe network must be drained to prevent freezing (such as touristand recreational resort buildings that are closed in winter, and the fire protection system must be drained to prevent freezing).
