Embodiment Construction

[0040] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0041] Such as Figure 1-Figure 8 As shown, the sealing ring replacement device of spherical crown type observation window in this embodiment includes a flange 21, on which a window seat 22 is installed through a plurality of O-rings 28, and a spherical crown type observation window is installed on the window seat 22 23. A pressure ring 24 is installed on the circumferential surface of the connection between the spherical crown observation window 23 and the window seat 22 through the pressure ring rubber pad 26 and the sealing device. At the same time, the pressure ring 24 is locked with the window seat 22 through the hexagon socket bolt 31; The circumferential direction of the window seat 22 is also installed with a plurality of replacement tooling 10 at intervals,

[0042] The structure of single replacement frock 10 is: comprise bearin...

Abstract

The invention relates to a spherical cap type inspection window seal ring replacing device and a replacing method. The replacing device includes a flange, a window seat is mounted on the flange through a plurality of O-shaped rings, a spherical cap type inspection window is mounted on the window seat, a compressing ring is mounted on the circumferential surface of the joint of the spherical cap type window and the window seat through a compressing ring rubber blanket and a sealing device, and meanwhile, the compressing ring and the window seat are locked through an inside hexagonal bolt; and aplurality of replacing tools are further mounted in the circumferential direction of the window seat at intervals, the replacing tools includes a supporting seat, the rear end of the supporting seatextends upwards to form a right-angle frame, a through hole is formed in one of the right-angle sides of the right-angle frame, a long bolt is mounted on the through hole, thus the through hole is connected with the window seat and the flange, locking is conducted through a first nut, the bottom of the front end of the supporting seat extends downwards to form a mounting sleeve, the mounting sleeve is internally loaded with a lead screw and is fixed through a second nut, a pressing plate is fixed to the bottom of the lead screw, and the bottom surface of the pressing plate abuts against the spherical cap type inspection window through a tool rubber blanket. Work is reliable, and dismounting is convenient.

Description

technical field [0001] The invention relates to the technical field of maintenance of manned submersibles, in particular to a replacement device and method for sealing rings of spherical crown observation windows, which are suitable for large-size spherical observation windows. Background technique [0002] In order to meet the needs of the occupants to maximize the observation field, the large-size spherical crown observation window has gradually become the standard design of manned submersibles. In order to prevent external sea (fresh) water from entering the manned compartment, a sealing ring is usually installed in the sealing groove formed by the spherical crown observation window, the metal window seat and the pressure ring. Due to the aging of the sealing ring, in order to ensure the sealing performance of the structure, the sealing ring needs to be replaced regularly. Since the spherical crown observation window is fixed only by the preload of the pressure ring, the...
