In the boss of portion's design.
The tight retaining ring of Zola and the right boss structure quantity tensed in retaining ring of being mounted on is 4~8.
The stretching screw is hex head screw, and head of screw is embedded in anti-rotation stop in the right hex-shaped recess for tensing retaining ring
It is dynamic.
The quantity of the stretching screw is 4-8.
The sealing ring uses O-ring seal.
The left pressure hull is segmented into one section of compressive cabin of submarine navigation device, is thin-wall tubular structure, internal both ends
There is boss structure for installing the tight retaining ring of Zola.
The connection segment is cylindrical structure, and there is seal groove at both ends, is equipped with sealing ring, and left pressure hull segmentation and the right side are resistance to
Pressure housing segments are socketed on connection segment both ends respectively.
The right pressure hull is segmented into one section of compressive cabin of submarine navigation device, is thin-wall tubular structure, internal both ends
There is boss structure for installing the tight retaining ring of Zola.
The beneficial effect of the utility model compared with prior art is:
Two pressure hull segmentations are connected to by the utility model by being segmented interior design connection structure in pressure hull
Together, it avoids and punches, slots on pressure hull, to improve the compressive resistance of entire shell, in addition also make entire water
Lower aircraft appearance is neat and artistic, reduces frictional resistance.
