Differential pressure prevention fireproof floor drain core device and differential pressure prevention fireproof floor drain core device testing device
The invention discloses a differential pressure prevention fireproof floor drain core device and a differential pressure prevention fireproof floor drain core device test device. The differential pressure prevention fireproof floor drain core device comprises a main body, a floating body and a sealing assembly, the main body comprises a base and a cavity mounted on the base, the base comprises a top wall, and a first tubular part and a second tubular part which protrude out of the upper end and the lower end of the top wall, the first tubular part and the second tubular part are coaxially arranged, and inner cavities of the first tubular part and the second tubular part are communicated; the floating body is mounted in an inner cavity of the cavity, and the bottom of the floating body is used for sealing the first tubular part; the sealing assembly is connected with the base and used for sealing the second tubular part. The device can be directly mounted at the mounting position of an original fireproof floor drain without changing a site civil engineering structure, whether floor drain liquid can be sucked away or sprayed out in a room with pressure difference or not can be avoided, the integrity of a fireproof partition can be achieved, in addition, the function of solving various working conditions (positive and negative pressures of the room do not need to be considered) through the scheme type of one floor drain can be achieved, and the practicability is high. The application range is wide, and the applicability is high.
本发明公开一种防压差防火地漏芯装置及防压差防火地漏芯装置试验装置，该防压差防火地漏芯装置包括主体、浮体以及密封组件；主体包括底座以及安装于底座上的腔体，底座包括顶壁，以及突出于顶壁上下两端的第一管状部和第二管状部，第一管状部与第二管状部同轴设置且二者内腔连通；浮体安装于腔体的内腔，且浮体的底部用于密封第一管状部；密封组件与底座连接，用于密封第二管状部。该装置可在原防火地漏的安装位置直接安装，无需改变现场土建结构，在有压差的房间内能否放置地漏液被吸走或喷出，可实现防火分区的完整性，除此之外，还可实现一种地漏的方案类型解决多种工况(无需考虑房间的正负压)的功能实现，适用范围广，适用性强。
