- 产品描述 :
- FM认证FM认证湿式报警阀是喷淋系统最常用的报警阀,系统用于温度在4℃以上的应用场所。 准工作状态时,系统管道内充满有压水,水在喷头动作后立即喷出灭火。
- 湿式报警系统主要应用在仓库、工厂、医院、商店、购物中心、住宅建筑等场所。
- FM认证FM认证湿式报警阀是分离阀座圈,橡胶衬面阀瓣,水流报警止回阀。 M认证报警阀附件包括:系统压力表、旁通止回阀、主排水阀和报警试验阀等。 旁通止回阀可使水压增加而产生的少量而缓慢的水流进行系统侧管道,而不使阀瓣开启,以降低误报警的可能性。
- Wet systems are the most common fire sprinkler system. A wet system is one in which water is constantly maintained within the sprinkler piping. When a sprinkler activates this water is immediately discharged onto the fire. Wet systems are frequently installed in factories, warehouses, office buildings, retail stores, and residences where the potential for freezing does not exist.
