Description

Sealing connection device
Technical Field
The invention belongs to the technical field of sealing connection devices, and particularly relates to a sealing connection device.
Background
The high-energy liquid-phase fuel is thrown into the air through the explosive explosion throwing driving action, the high-energy liquid-phase fuel is atomized and mixed with the air to form a large-range active cloud cluster, and the active cloud cluster generates body detonation through secondary detonation of the explosive to release strong shock waves, so that the high-energy liquid-phase fuel weapon is one of the most powerful weapons.
The high-energy fuel filled in the body detonation warhead part contains liquid-phase materials, so that all parts in the body detonation warhead part, which are contacted with the high-energy fuel, need to have sealing performance, and mechanical interfaces of a shell, front and rear end covers, a loading port, a cable-passing line pipe, a throwing powder pipe and the like of the body detonation warhead part need to meet the sealing requirements.
The most common seal design for mechanical interfaces is an axial seal with an end face. Jiang Yu et al report in the literature "static seal design of an O-ring and its application to a vent valve" (guangdong chemical, 2017, vol 44, page 19, 148): the axial sealing structure of the end face is simple and widely applied. The O-shaped rubber sealing ring can simplify the installation steps and reduce the leakage risk caused by human factors. The end face axial sealing structure is composed of two parts, an end face axial sealing groove is machined in one part, an O-shaped rubber sealing ring is placed in the sealing groove, a cover plate part is installed, and the O-shaped rubber sealing ring is compressed and is tightly attached to the two parts at the same time, so that sealing is achieved.
However, the end face axial sealing structure has the following problems in the actual use process:
the body detonation warhead has a compact structure, the size of a sealing groove is very accurate, the diameter of the sealing ring has tolerance, the diameter error of the sealing ring with the diameter of 600mm is +/-3.2 mm, and when the diameter of the sealing ring is larger, the sealing ring has outward expansion stress in the sealing groove, so that local outward tilting is easily caused; when the diameter of the sealing ring is smaller, the sealing ring has inward expansion stress in the sealing groove, and local inward tilting is easily caused. And because of charging, part of the mechanical interfaces of the body detonation warhead need to be repeatedly disassembled, the sealing ring is lengthened after being compressed every time, the diameter of the sealing ring is gradually enlarged, and the effect is the same as that when the diameter of the sealing ring is larger.
In case the sealing washer is local perk in following the seal groove, the position of sealing washer perk will break away from the seal groove, and when installing the installation apron part again, the extrusion force of two machine parts will make the sealing washer cut off to lead to the sealing washer local destruction, and then lead to the body detonation warhead to leak, warhead inefficacy.
