Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2, structure of the present utility model is, including columnar shell 1, at shell 1
Outer wall top has rectangular window, and this rectangular window is installed with pressure compensator 2；Shell 1
Bottom flange (by high-strength stainless steel bolt) is connected with bottom 3, between bottom flange and bottom 3
Contact surface sealing ring 1 is installed, the sealing protection between shell 1 and bottom 3；At bottom
The bottom surface of 3 is installed with valve island 5, and valve island 5 is internal to be had and the passage of shell 1 inner space,
Valve island 5 passage is provided with tapping valve 6 and liquid feed valve 7, tapping valve 6 and liquid feed valve 7 respectively the most side by side
For control and compensation liquid into and out of the flow direction, valve island 5 is provided with sealing gasket 9 with the contact surface of bottom 3；
Air bleeding valve 8 is installed on the top cover 18 of shell 1, air bleeding valve 8 and shell 1 inner chamber (referred to as sealed compartment or
Equipment compartment) connection.
With reference to Fig. 2, the structure of pressure compensator 2 is, including protective cover 10, protective cover 10 inner chamber
Being provided with leather bag 11, leather bag 11 is sitting in protective cover as pressure compensated energy storage device, leather bag 11 bottom
On a rubber blanket 12 on 10 base plates, another rubber blanket 12 above leather bag 11 and protective cover 10
Cover plate 13 fixing connect, cover plate 13 is fixedly mounted on top cover 18；The spigot joint of leather bag 11 bottom is led to
Cross clamp nut 15 to be fixed on the base plate of protective cover 10, clamp nut 15 and the base plate of protective cover 10
Contact surface is provided with sealing ring 2 14；The spigot joint downward connection of leather bag 11 has stainless steel tube 16, rustless steel
Pipe 16 stretches in shell 1 inner chamber, for communication seals cabin and leather bag 11.
Protective cover 10 and shell 1 are integral by being welded and fixed, by complete for the rectangular window on shell 1
Block so that shell 1, top cover 18, bottom 3 and protective cover 10 surround a sealing cabin, it is simple to
Each Functional Unit device is installed in shell 1 inner chamber.
Shell 1 and protective cover 10 all use thin-walled steel plate to be welded as drum, shell 1 and protective cover
10 is all the thin-walled steel plate using thickness less than 8mm.
Leather bag 11 upper/lower terminal is respectively adopted a rubber blanket 12 and carries out resilient protection, its middle and upper part
Certain gap is left on rubber blanket 12 and leather bag 11 top, it is simple to leather bag 11 upwards upholds expansion, root
The corresponding volume of actually active spatial match leather bag 11 and the leather bag (embodiment of quantity according to shell 1 inner chamber
It is two groups of leather bags 11).
With reference to Fig. 3, cover plate 13 is fixed by screws on the top cover 18 of shell 1, cover plate 13 has
Multiple balancing orifices 17, the installation place of leather bag 11 (position of opening of balancing orifice 17 be distributed on), for will be anti-
The inner chamber of guard shield 10 turns on sea water, makes the pressure of outside sea water act directly on leather bag 11.
Work process of the present utility model is,
1) before subsea control modules enters water, by the liquid feed valve 7 on bottom 3 to shell 1 inner chamber and skin
Capsule 11 fills non-conductive liquid medium, the air in leather bag 11 must be emptied before topping up as far as possible, and beat
The air valve 8 that begins to rehearse empties the air in shell 1 inner chamber；Leather bag 11 and shell 1 inner chamber are full of liquid medium
After, close air bleeding valve 8.
2) in subsea control modules decentralization process, along with the increase of underwater penetration, in the pressure of extraneous sea water
Under power effect, sea water enters protective cover 10 inner chamber compressing leather bag 11 by balancing orifice 17, and leather bag 11 is not
After disconnected contraction, liquid medium of its interior filling is persistently passed in shell 1 inner chamber by stainless steel tube 16,
Make in shell 1 inner chamber intrinsic pressure is stepped up, until keeping consistent with external seawater pressure, so that
Shell 1 inner chamber is inside and outside without pressure reduction, uses conventional seals circle (sealing ring 1 and sealing ring 2 14) just may be used
To reach subsea control modules is sealed the effect of protection.
3) same, subsea control modules carries in removal process, along with the reduction of seawater pressure, shell 1
Liquid medium in inner chamber is constantly pushed back in leather bag 11 so that intrinsic pressure in shell 1 inner chamber progressively drops
Low, keep consistent with external seawater pressure all the time.
4), after subsea control modules disembarkation, open tapping valve 6 and air bleeding valve 8, shell 1 inner chamber is neutralized
Liquid medium emptying in leather bag 11, can open the cabin each Functional Unit device of maintenance.
