Full-automatic water seal type double-seal explosion-proof floor drain
The invention discloses a full-automatic water seal type double-seal explosion-proof floor drain, belongs to the field of civil air defense engineering, and aims to provide a water seal type floor drain which can be automatically and reliably closed under the action of shock waves and is of a non-bell jar type structure, so that the water seal type floor drain can automatically prevent poison gas of the shock waves from entering a protection area in wartime. And meanwhile, the structural form of the device conforms to the specification of GB55020-2021 General Standard for Water Supply, Drainage and Water-saving for Building. The assembly comprises a drain body, a grate, an upper sealing cover, a connecting rod mechanism, a fixed connecting rod shaft, a lower sealing cover, a balance spring, a lock key, a V-shaped spring piece, an internal thread pin, a countersunk bolt and a T-shaped sealing ring. Compared with an existing explosion-proof floor drain, the explosion-proof floor drain can be automatically closed and automatically locked under the action of shock waves, and bidirectional reliable sealing can be achieved under the condition that the explosion-proof floor drain is stressed in one direction; the drain body and the bowl-shaped lower sealing cover form a good water seal, the water seal cannot be damaged under the condition that the upper sealing cover is detached, and odor and poison gas can be effectively prevented from entering a protection area.
本发明的名称为全自动水封式双密封防爆地漏，属于人防工程领域，旨在提供一种在冲击波作用下能够自动可靠封闭且非钟罩式结构的水封式地漏，使其在战时能够自动防止冲击波毒气进入防护区，同时其结构形式符合GB55020‑2021《建筑给水排水与节水通用规范》规定。本发明的组件包括漏体、箅子、上密封盖、连杆机构、固定连杆轴、下密封盖、平衡弹簧、锁键、V型弹簧片、内螺纹柱销、沉头螺栓、T型密封圈。与现有防爆地漏相比，本发明在冲击波作用下能够自动封闭和自动锁止，并能在其单向受力的情况下实现双向可靠密封；其漏体与碗形下密封盖形成良好水封，上密封盖拆除的情况下也不会破坏水封，可以有效防止臭气、毒气进入防护区域。
