Description

[根据细则37.2由ISA制定的发明名称]　双侧抗冲击波的抗爆阀及其阀体 技术领域
本发明涉及建筑的新风入口和排风出口的暖通设备，特别是存在潜在爆炸冲击波危害的建筑物的新风入口和排风出口的通风阀，尤其是一种能起到双侧抗冲击波防护的通风抗爆阀及其阀体。
背景技术
爆炸冲击波主要有两个阶段会产生较大破环：第一阶段是爆炸发生时爆炸中心点随之放出几万个大气压的冲击波。冲击波以球面形式高速向四周移动，此冲击波所对物体具有很大的冲击破环力。随之冲击波移动距离的增加，冲击波的压力会迅速衰减；第二阶段是爆炸中心点的空气由于波动的惯性作用，发生空气收缩产生负压，伴随而来的是一次强负压波。负压波产生时，建筑内气压大于室外气压，从而对通风阀产生自内而外的推力。一定强度的负压波同样会对建筑物内设施造成破环，特别是在通风阀靠爆炸中心很近的时候。
如图1、图2所示，现有技术的双侧抗冲击波通风阀，多采用1个到3个截面为方形、圆形或其他形状的阀芯B2，通过前后平行运动的方式进行关闭和开启通风通道。正常通风时，阀芯B2处于中间平衡位置，提供通风功能。当发生爆炸冲击时，施加于阀芯B2的冲击波压力使阀芯关闭，阻挡冲击波进入建筑物或通风系统受保护的一侧；当冲击波从正压转为负压时，阀芯向另一侧运动，减小通风通道，直至负压使阀芯关闭通风通道。但现有的抗冲击波通风阀采用大阀芯设计，其开口B3长度长，结构强度低，因此抗高强度冲击波能力有限(目前最高抗爆能力为高反射压12bar，持续70ms左右)；此外，其单个阀芯重量大，在一定冲击波的冲量下获得的初始速度慢，导致关闭时间长，因而会有较大一部分冲击波能量透过阀体，对受保护侧人员和设施存在一定的风险。
技术问题
本发明的发明目的之一是，提供一种能提高抗爆强度的阀体。
本发明的又一发明目是，提供一种能提高抗爆强度及反应速度的阀体组。

发明的有益效果
有益效果
现有技术抗冲击波通风阀采用大阀芯设计，阀体中供通风通道的开口长度长，单个阀芯重量大，结构强度低，阀芯在冲击波的冲量下获得的初始速度低。
而采用本发明的所能实现的有益效果为：
1)框体内设两相交的支撑体，支撑体上间隔设有贯通槽(现有技术中用于通风的开口)长度较短，故而单个阀芯重量和体积大幅减小，由于阀芯重量减低，在冲击波的冲量下获得的初始速度快，关闭通风通道的时间变短，大大提高了在冲击波到来时阀芯的反应速度。现有技术中，在10bar反射压力下，阀芯反应速度为1ms，本发明阀芯的反应速度为0.5ms。
2)相同规格的抗爆阀，本发明单个阀芯重量仅为现有技术单个阀芯重量的1/10。
3)本发明中承受冲击的部分由两相交的支撑体和框体共同形成三角支撑排架，大大提高了抗爆主体的抗爆性能，现有技术的同类型双侧抗冲击阀仅能抗反射压峰值为12Bar的冲击波的多次冲击，本发明可以承受反射压峰值为60Bar的冲击波的多次冲击，抗爆等级大大提高。
