Technical field
This utility model is related to hydraulic compensating device, particularly to a kind of pressure compensation device of deep-sea hydraulic system.
Background technology
In recent years, with world population sharp increase ecological deterioration, land resource is progressively deficient, and the research to deep-sea is increasingly subject to
To the attention of all circles, it is applied to the deepwater hydraulic system of the tasks such as sea floor exploration it is necessary to consider hydraulic pressure and seabed adverse circumstances pair
The impact of system, therefore, increasing underwater hydraulic system is also born therewith.
In the prior art, some underwater hydraulic systems to realize water using Underwater Pressure static organ or pressure compensator
The compensation of pressure；Also have the research worker of some underwater hydraulic systems in order to eliminate hydraulic pressure rigid by pressure compensated compensation hydraulic list
Unit is mixed with hydraulic system and is developed；For the pressure compensation of some underwater robots or underwater construction equipment, mesh
Before have some special pressure compensator products.These pressure compensation modes above-mentioned can eliminate the impact to system for the hydraulic pressure, but
It is with executor, hydraulic control component to be placed in this traditional approach in a pressure vessel that can bear hydraulic pressure can bring system
A series of problems, such as energy of heaviness, complex structure and special dynamic sealing and extra consumption system.In view of this, the present invention provides
A kind of structure is simple, seal request is low and can automatically adapt to the deep-sea hydraulic system pressure compensation dress of different pressures environment
Put.
Utility model content
In order to solve the problems, such as that pressure compensating system volume and weight of the prior art is big, seal request is high, this practicality
New provide a kind of pressure compensator.
In order to solve above-mentioned technical problem, this utility model employs the following technical solutions：
A kind of pressure compensation device of deep-sea hydraulic system, it includes 316L corrugated stainless steel tubing cavity, and inside cavity irrigates
Filling liquid, cavity two ends are respectively provided with flat head, one end flat head is located inside cavities and installs gripper shoe, in gripper shoe
Hydraulic component is installed, other end flat head is respectively provided with sea water inlet channel, sea water outlet conduit and filling liquid import
Pipeline.
Preferably, the filling liquid that this utility model provides is methyl-silicone oil.
Preferably, passing through Bolted Flanged Connection between corrugated tube cavity and two ends flat head, sealed by O-ring.
Preferably, the pressure compensator that this utility model provides, between its flat head and gripper shoe, pass through screw
Connect.
Preferably, the pressure compensator that this utility model provides, it is installed outside the flat head of gripper shoe one end
Setting underwater electrical connector.

This utility model provides a kind of pressure compensation device of deep-sea hydraulic system, and it includes 316L corrugated stainless steel tubing chamber
Body, inside cavity irrigates filling liquid, and cavity two ends are respectively provided with flat head, one end flat head is located inside cavities and installs
Gripper shoe, gripper shoe installs hydraulic component, other end flat head is respectively provided with sea water inlet channel, sea water outlet pipe
Road and filling liquid inlet pipeline.Compared with pressure compensating system of the prior art, there is advantages below in this utility model：First
First, the corrugated stainless steel tubing chamber that this utility model adopts can occur elastic deformation, is realized by the elastic deformation of bellows chamber
Pressure compensation, thus reach inside and outside pressing weighing, and then eliminates the impact of extraneous high pressure sea water；Furthermore, this utility model is using carrying
For pressure compensation device can be substantially reduced the volume of system, reduce seal request, make overall structure simple, material-saving；Finally,
It is connected using flange bolt between flat head and cavity, convenient dismounting, therefore whole device can better conform to different pressures
Abyssal environment.
Brief description
Fig. 1 is the structural representation of pressure compensation device of deep-sea hydraulic system provided by the utility model.
Specific embodiment
This utility model aims to provide a kind of pressure compensation device of deep-sea hydraulic system, is mended with solving pressure in prior art
Repay system bulk and weight is big, seal request is high problem.
In order that those skilled in the art can be better understood from this utility model, with reference to specific embodiment and attached
The utility model is described in further detail for figure.
A kind of pressure compensation device of deep-sea hydraulic system, it includes 316L corrugated stainless steel tubing cavity 1, and cavity 1 is internal to be filled
Note filling liquid 9 (methyl-silicone oil), cavity two ends are respectively provided with flat head 2, one end flat head is located inside cavities and installs
Gripper shoe 3, gripper shoe installs hydraulic component 4, other end flat head is respectively provided with sea water inlet channel 5, sea water goes out
Waterpipe 6 and filling liquid inlet pipeline 7；Wherein, pass through Bolted Flanged Connection between corrugated tube cavity and two ends flat head, lead to
Cross O-ring 8 to seal, be connected by screw between flat head 2 and gripper shoe 3, it is installed outside the flat head of gripper shoe one end
Side arranges underwater electrical connector 10, and hydraulic component described in the utility model can include valve and pump.
When bellows chamber is subject to extraneous seawater pressure, elastic deformation is occurred to lead to the methyl-silicone oil in bellows chamber to exist
Compressed in the presence of pressure.From physically, the total compression volume of methyl-silicone oil and subtracting of the cavity volume of corrugated tube
The difference of small size to be compensated by the deformation volume of corrugated tube.During this volume compensation, the external pressure of corrugated tube is outer
Boundary's seawater pressure, and intrinsic pressure be methyl-silicone oil in corrugated tube pressure, from upper analysis, this two pressure are equal
, therefore the interior external pressure of ripple tube body is balance.When hydraulic work system, the internal flow of hydraulic component is to pass through
The fluid equal with extraneous hydraulic pressure that sea intake pipeline flows into, and the external pressure of hydraulic component is also derived from methyl silicon in corrugated tube
The pressure of oil, from upper analysis, this two pressure are equal, therefore the interior external pressure of the hydraulic component encapsulating in corrugated tube
It is balance.Then, in corrugated tube and tube chamber, the interior external pressure of the hydraulic component of encapsulation has also all reached balance.
Above a kind of pressure compensation device of deep-sea hydraulic system provided by the utility model is described in detail.
Specific case used herein is set forth to principle of the present utility model and embodiment, and the explanation of above example is only
It is to be used to help understand method of the present utility model and central idea.It should be pointed out that the general technology people for the art
For member, on the premise of without departing from this utility model principle, this utility model can also be carried out with some improvement and modify, this
A little improvement and modification also fall in this utility model scope of the claims.
