Description

Technical Field

[0001] The utility model relates to the technical field of sealing equipment, in particular to a sealing sleeve for a driving device of a missile launching tube. Background Technique

[0002] The missile launching tube is an important part of the missile weapon system. The bottom can be welded to the pressure-resistant shell of the submarine. After the missile is loaded into the launching tube and sits on the support ring, the missile tail, the wall of the launching tube and the pressure-resistant shell of the submarine jointly form a sealed space at the bottom of the tube. When the missile is launched, the ejection power system ignites, and the mixed gas of gas and steam is blown into the bottom of the tube through the power boss pipeline at the set flow rate and velocity to establish a pressure field at the bottom of the tube, thereby pushing the missile upward and ejecting the missile out of the launching tube.

[0003] The missile launch requires the assistance of a driving device at the bottom of the launching tube. During the installation process of the driving device, a sealing sleeve is needed to limit and seal the device. The existing sealing sleeves need to be customized according to the size of the driving device. Inevitably, errors will occur in the customized production of the sealing sleeves, which will affect the limitation and sealing of the driving device. Moreover, the lengths of the driving devices are different, and the existing sealing sleeves cannot be adapted, resulting in affecting the installation. Therefore, we provide a sealing sleeve for a missile launching tube driving device to solve the above problems. Content of the Utility Model
