An outer pipe of the catapult is provided with parallel openings in the axial direction, an inner pipe is a spiral opening with the screw pitch being the length of one unit, and three spiral supporting sealing strips are arranged on the two sides of the spiral opening and the symmetrical positions of the opening. Rotary sealing pipes with return chamfers are arranged at the two ends of the outer pipe. And the piston is connected with the drag hook through the crossed inner and outer tube openings. Openings of the inner pipe and the outer pipe intersect to form sealing; the piston is connected with an external drag hook through an intersection; a rotary sealing pipe and a return spring are arranged at the joint of each section to ensure the sealing when the piston does not pass through; when the piston passes through, the piston attack angle impacts the return chamfer, the rotary sealing pipe rotates, the opening of the rotary sealing pipe is consistent with the opening of the outer pipe, and it is guaranteed that the piston passes through. Inner pipe steam and the outside are sealed through two layers of steel pipes and sealing strips embedded in the inner pipe, and high-pressure gas can be sealed. And each sealing surface is sealed between a soft material and a metal material, so that the sealing performance can be ensured, and high-pressure gas can be borne. The zipper seal is used for dust prevention and does not bear high pressure.
弹射器外管是沿着轴向平行开口的,内管是螺距为一个单元长度的螺旋开口,螺旋开口两侧及开口对称位置设置3条螺旋支撑封条。外管两端是具有回位倒角的旋转密封管。活塞通过内外管开口交叉开口连接拉钩。内外两管开口交叉形成密封,活塞通过交叉口连接外部拉钩;在每段连接处由旋转密封管及回位弹簧保证活塞没有通过时的密封;当活塞通过时,活塞冲角撞击回位倒角,使得旋转密封管旋转,使得旋转密封管的开口和外管开口一致,保证活塞通过。内管蒸汽与外界的密封靠两层钢管及镶嵌在内管上的密封条进行密封,可以密封高压气体。各个密封面都是软体材料和金属材料之间的密封,可以保证密封性能,并且承受高压气体。拉链密封用作防尘,不承受高压。
