Sealing structure for low-speed pressurization wind tunnel section
The invention discloses a sealing structure for a low-speed pressurization wind tunnel section, which comprises a sealing ring and a sealing groove, a circle of sealing groove is installed at the sealing position of the low-speed pressurization wind tunnel section, the sealing ring is installed in the sealing groove, the sealing ring is hollow, the interior of the sealing ring can be inflated, and when the sealing ring is not inflated, the sealing ring is sealed by the sealing groove. The top of the sealing ring is recessed towards the middle, the top of the sealing ring is flush with the outer edge of the sealing groove, positioning strips are fixed to the inner walls of the two sides of the sealing groove respectively, a certain distance is reserved between the lower ends of the positioning strips and the inner plane of the bottom of the sealing groove, and integrated outwards-protruding reverse hook structures are arranged on the lower portions of the two side walls of the sealing ring. The reverse hook structure can be connected with the bottom end face of the positioning strip in a clamped mode and makes contact with the side wall of the sealing groove located at the lower end of the positioning strip. The sealing device has the advantages of simple structure, good sealing effect, high sealing ring positioning capability and low probability of extrusion damage.
本发明公开一种用于低速增压风洞截面的密封结构，包括密封圈和密封槽，在低速增压风洞截面的密封处安装有一圈密封槽，所述的密封圈安装在密封槽内，所述的密封圈为中空，其内部能够充气，当所述的密封圈未充气时，所述的密封圈的顶部向中间凹陷，并且密封圈顶部与密封槽外沿平齐，所述的密封槽的两侧内壁分别固定有定位条，所述的定位条的下端与密封槽的底部内平面有一定的距离，所述的密封圈的两侧壁下部设置有一体的外突的反钩结构，所述的反钩结构能够与所述的定位条的底部端面卡接，并与位于定位条下端的密封槽侧壁相接触。本发明具有结构简单、密封效果好、密封圈定位能力强，不易发生挤压破坏的优点。
