Piston type anti-blast-wave valve for ventilation opening of protective engineering
The invention discloses a piston type anti-blast-wave valve for a ventilation opening of protective engineering. The piston type anti-blast-wave valve comprises a door body, a door frame, a hinge, a lock and piston units, the door body is connected to the door frame through the hinge and is locked through the lock, the piston units are arranged on the door body at intervals, the door body comprises a door leaf base and a front panel, the front panel is arranged on the door leaf base, first ventilation holes are formed in the front panel at intervals, a spring supporting base is arranged on the door leaf base and is connected to the inner side surface of the front panel, the piston units are arranged on the front panel, and the inner ends of the piston units extend into the first ventilation holes and are connected to the spring supporting base. According to the piston type anti-blast-wave valve, the piston units are arranged as a closing component for bearing blast wave pressure and conducts linear motion inwards under the action of blast wave overpressure to close the valve, the beneficial effects of small ventilation resistance, high wave absorbing efficiency, wide resistance range and high environment applicability can be achieved, the impact of blast waves on the door leaf base can be effectively reduced; and a safe and reliable protection function is achieved.
本发明公开了一种防护工程通风口用活塞式防爆波活门，包括门体、门框、铰页、闭锁和活塞单元，门体通过铰页与门框连接，并通过闭锁锁闭，活塞单元间隔设置在门体上；门体包括门扇底座和前面板，前面板设在门扇底座上，前面板上间隔设有通风孔一；门扇底座上设有弹簧支撑座，弹簧支撑座连接在前面板的内侧面上，活塞单元设在前面板上，其内端伸入通风孔一中并连接在弹簧支撑座上。本发明设置活塞单元作为承载冲击波压力的关闭构件在冲击波超压的作用下向内做直线运动关闭活门，具有通风阻力小、消波效率高、抗力范围宽以及环境适用性强的优点，能够有效降低冲击波对门扇底座的冲击，实现安全可靠的防护功能。
