The high-airtightness anti-clamping stagnation pressure wave protection valve comprises a mounting bottom plate, a plurality of first connecting through holes are vertically formed in the ends of the two sides of the mounting bottom plate, and a plurality of second connecting through holes are vertically formed in the positions, close to the first connecting through holes, of the two sides of the mounting bottom plate; and the plurality of first connecting through holes are fixedly connected with two short brackets through a plurality of first bolts respectively. A top plate is not needed for supporting, the reinforcing rib plates are adopted for guaranteeing the structural stability, the using amount of sectional materials is reduced, then the overall weight is reduced, the movable plate is opened in a side-opening rotating mode, the sealing rotating plate is guided and limited through the shaft rod, and compared with a traditional upper and lower sealing plate mode, a guide groove structure does not need to be additionally arranged; the sealing plug bush is arranged in the nut piece structure, the sealing plug bush is inserted into the through hole during installation, the through hole in the installation position is further sealed, and air tightness is guaranteed.
本发明公开了一种高气密性防卡滞压力波保护阀,包括安装底板,所述安装底板两侧端部垂直开设多个第一连接通孔,所述安装底板两侧靠近第一连接通孔位置垂直开设多个第二连接通孔,多个所述第一连接通孔通过多个第一螺栓分别固接两个短支架。本发明不需要顶板支撑,采用加强筋板保证结构稳定性,型材量使用减少,进而减轻了整体重量,并使用侧开转动的方式打开动板,通过轴杆对密封转板进行导向限位,对比传统上下密封板的方式,无需增设导向槽结构,从根源避免了导向槽卡死导致密封板卡滞的情况,本发明螺母件结构中设置了密封插套,在安装时,密封插套插在通孔内部,对安装处的通孔进行进一步的密封,保证了气密性。
