Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] combined with figure 1 and figure 2 , the flange 12 is pre-tightened to the glass window by the M6 ​​titanium alloy screw 4. The polytetrafluoroethylene gasket 3 plays the role of protecting the glass and adjusting the size and location of the glass during the pre-pressing process. The end of the shell is pre-tightened to the head cover 8 by M6 titanium alloy screws. There are two radial seal grooves on the side wall of the window seat hole, which are used to arrange two radial seal rings and retaining ring 3 to form the main seal; there is an end seal groove on the bottom plane of the conical surface of the window hole, which is used to arrange the end face seal Ring and back-up ring 5 form a secondary seal. Once two of the main radial seals fail and leak occurs, the fluid flow will turn 90° at the end face, and the frictional resistance can be reduced by ...

Abstract

A large depth ocean optical device capable of enhancing sealing comprises a glass window, a pre-tightening flange, a pressure resistant shell and a head sealing end cover. The large depth ocean optical device capable of enhancing sealing is characterized in that a sapphire pressure-proof conical optical glass is mounted in a window seat hole in the shell; an optical window flange applies a pre-tightening force to glass through a bolt; and the glass and the shell are sealed through an end surface O-shaped sealing ring and a retainer ring and a radial O-shaped sealing ring and a retainer ring. Apre-tightening force is applied between the head sealing end cover and the shell through a bolt; and the end cover and the shell are sealed by the radial O-shaped sealing ring and the retainer ring and the end surface O-shaped sealing ring and the retainer ring. A spherical cylindrical surface is matched with a pressure resistant flange, the pressure-proof glass and a pressure-proof end cover inappearance to realize pressure resisting. The large depth ocean optical device capable of enhancing sealing has the advantages that the sealing is simple and reliable; the structure is compact; deep sea large-depth 6000 m pressure resisting strength and stability are realized; and the large depth ocean optical device capable of enhancing sealing is suitable for carrying multiple optoelectronic system equipment.

Description

technical field [0001] The invention belongs to the technical field of pressure-resistant devices, and in particular relates to a large-depth ocean optical device with enhanced sealing. Background technique [0002] Deep-sea pressure-resistant optical devices generally arrange sealing rings and gaskets around the window glass, and then apply pre-compression force to these seals through pre-tightening flanges. After the optoelectronic equipment is installed, a seal is installed on the rear end of the housing to apply a pre-compression force through the end cover. [0003] The deep-sea anti-pressure device disclosed in the prior art, such as the patent No. CN200820066898.2 discloses a pressure-resistant sealing window. The O-ring arranged between the tapered glass cylindrical surface and the outer shoulder of the window hole is the first seal, and the second seal is realized by a polytetrafluoroethylene gasket between the glass cone surface and the pressure-bearing surface of...
