Description
Technical field
The invention belongs to marine system technical fields, and in particular to a kind of anti-seawater immersion with automatic Regulation function is close
Seal apparatus.
Background technique
Breather valve actuator is one of the important valve that submarine realizes floating dive, directly right due to sealing at its extension bar
Outer contacting seawater can make external seawater leak into Method for Inside Submarine's if sealing is bad, of a serious nature ship to be made to ruin people die.So right
Its Research on Seal is of great significance.Conventional seals are that O-ring is applied in combination with stuffing-box pattern, O-ring material and stuffing-box
Though there is the various different trades mark, it is rubber after all, very serious using its abrasion when long.It can generate different degrees of
Leakage, reduces the service life, need to frequently replace sealing material.
Summary of the invention
Present invention solves the technical problem that: the present invention provides a kind of anti-seawater immersion sealing dress with automatic Regulation function
It sets, when work varies with temperature pressure automatic adjustment, makes pressure control within a preset range, guarantees the leakproofness of product.
The technical solution adopted by the present invention:

Self-compensating pressure device, dustband；Oiling oil circuit and oil storage tank are opened up on a main housing；It is equipped between main casing and mandril general
Plug sealing, Ge Laiquan；Dustband is equipped at the top of main casing and ejector pin contact, self-compensating pressure device is mounted on main casing
On.
The self-compensating pressure device includes sealing ring, piston, disc spring group, pressure-pad, retaining ring；Piston is equipped with sealing
Circle, between piston and pressure-pad be equipped with disc spring group, pressure-pad and outside emit between be equipped with retaining ring.
The attachment of ejector pin contact seawater generated to outer portion can be carried out by dustband in actuator operational process
It removes, ensure that the finish of mandril motion parts.
The general plug is sealed into mainly to external seal, if general plug seal failure, there are also the first Doug Lai Quan also to have sealing to make
With if this sealing ring fails, pressure is higher than ambient pressure at oil storage tank at this time, and seawater is leaked less than in oil storage tank, increased
Whole aircraft reliability and service life.
The self-compensating pressure device, when the temperature increases, by changing seal chamber volume, automatic Regulation oil liquid pressure
Power.
Beneficial effects of the present invention:

Specific embodiment
In the following with reference to the drawings and specific embodiments to a kind of anti-seawater leaching with automatic Regulation function provided by the invention
Enter sealing device to be described in further detail.
As shown in Figure 1, a kind of anti-seawater with automatic Regulation function provided by the invention immerses sealing device, comprising:
Oil storage tank 1, general plug seal 2, lattice to enclose 3, self-compensating pressure device 4, dustband 5；Oiling oil circuit 8 is opened up on main casing 6
And oil storage tank 1；It is equipped with general plug between main casing 6 and mandril 7 and seals 2, lattice to enclose 3；The top and 7 contact position of mandril of main casing 6
Equipped with dustband 5, the installation of self-compensating pressure device 4 on a main housing 6.
As shown in Fig. 2, self-compensating pressure device 4 includes sealing ring 9, piston 10, disc spring group 11, pressure-pad 12, retaining ring 13；
Piston 10 is equipped with sealing ring 9, and disc spring group 11 is equipped between piston 10 and pressure-pad 12, and pressure-pad 12 and outer emit are equipped with retaining ring between 14
13。
The operation principle of the present invention is that:
In actuator operational process mandril 7 contact seawater to outer portion generate attachment can by dustband 5 into
Row is removed, and ensure that the finish of 7 motion parts of mandril.If ambient pressure is 3Mpa, set oil pressure at oil storage tank 1 to
3.5Mpa, in normal use process, general plug sealing 2 is main externally sealing, if 2 failure of general plug sealing, it is next that there are also the first Dougs
Circle 3 also has sealing function, if this sealing ring fails, pressure is higher than ambient pressure at oil storage tank 2 at this time, and seawater is leaked less than storage
In oil groove, whole aircraft reliability and service life are increased.
Environment temperature difference is larger when due to the work of breather valve actuator, when the temperature increases, due to Elastic Modulus for Metals
Very big, annular groove volume will not become larger therewith, then can increase with the rising oil liquid pressure of temperature at this time, annular groove oil pressure is excessively high unfavorable
It is sealed in Ge Laiquan 3, so self-compensating pressure device 4 is varied with temperature devising with the annular groove place of communicating, when temperature increases
When, by changing seal chamber volume, make its automatic Regulation.
The piston 10 of selection suitable area and suitable disc spring group 11, when the temperature increases, internal pressure increases, piston 10
Internal pressure can be changed and be converted into displacement, a constant volume can be discharged by the deformation oil liquid of disc spring group 11, reduce oil pressure, instead
It, temperature reduces, and since disc spring group 11 has precompressed, reduces a constant volume, increases oil pressure.It thus can reach pressure regulation purpose.
