Equipped with sealing ring 4, one end outer surface of sealing ring 4 and 2 inner surface of annular end cap cooperate, the other end of sealing ring 4
Outer diameter gradually becomes smaller along the center line of sealing ring 4, and one end of clamping cap 3 is an annular, the outer wall and pressure of the other end of sealing ring 4
The inner wall of one end of tight lid 3 is fitted close, and the internal diameter of one end of clamping cap 3 gradually becomes smaller along the other end center line of clamping cap 3,
The other end of clamping cap 3 is threadedly secured on annular end cap 2.
Sealing structure of the invention is mutually fitted close to realize sealing by sealing ring 4 and clamping cap 3, sealing ring 4
Other end outer diameter gradually becomes smaller, and 3 internal diameter of clamping cap matched with sealing ring 4 also gradually becomes smaller, close when cylinder initial sealing
The other end of seal ring 4 is sealed in clamping cap 3, with the pressure increase in cylinder 1, since clamping cap 3 is fixed, sealing ring
When 4 water in cylinder 1 applies pressure to it, it is tightly pushed into clamping cap 3, since 3 internal diameter of clamping cap is smaller and smaller, is made
Sealing ring 4 is obtained closely to be caught in clamping cap 3.It can thus be appreciated that sealing ring 4 is more tightly caught in as cylinder internal pressure increases
In clamping cap 3, keep the cooperation of the two all the more close, leakproofness is better, efficiently solves leak and sea cable water permeabillity test accuracy rate
Purpose.
When it is implemented, the inner wall of the other end of annular end cap 2 is equipped with second boss 21, second boss 21 and clamping cap
There are gaps between the end face of 3 one end；The longitudinal section of sealing ring 4 is truncated cone-shaped, and one end of clamping cap 3 has cavity, cavity
The insertion of sealing ring 4 for reverse frustoconic, truncated cone-shaped has in 3 one end of clamping cap of reverse frustoconic cavity.Second boss 21 and pressure
There are gap between the end face of one end of tight lid 3, the space of one deformation when this is squeezed to sealing ring 4 by end cap；Truncated cone-shaped it is close
The cooperation of the clamping cap 3 of seal ring 4 and reverse frustoconic cavity, further improves leakproofness.
When it is implemented, the longitudinal section of one end of clamping cap 3 is inverted wedge shape, the mutual wedge in one end of sealing ring 4 and clamping cap 3
Shape cooperation.Wedge structure is simple, when sealing ring 4 is by radial pressure, the angle of wedge on obcuneate clamping cap 3 insertion sealing ring 4 with
Gap between end cap so that clamping cap 3 cooperate with sealing ring 4 it is even closer.
When it is implemented, sealing ring 4 includes the first sealing ring 40 and the second sealing ring 41, an end face of the first sealing ring 40
Close to first boss 20, one end of the first sealing ring 40 is cylinder ring, and the other end of the first sealing ring 40 is hollow round table, first
The outer wall of one end of sealing ring 40 and the inner wall of annular end cap 2 cooperate, the outer wall and clamping cap 3 of the other end of the first sealing ring 40
One end inner wall interference fit, the end face of one end of clamping cap 3 and second boss 21 are opposite, and the interior of clamping cap 3 compresses without leave
It rises and is gradually reduced in one end of lid 3；Second sealing ring, 41 inner wall and sea cable outer wall cooperate；It is arranged on second sealing ring, 41 outer wall
One circle chamfering, 40 inner wall of the first sealing ring and 41 outer wall of the second sealing ring cooperate.Generally there are 3MM for sea cable oversheath diameter
Within deviation, sealing ring 4 is separated into the first sealing ring 40 and the second sealing ring 41, it is very convenient to be mounted in sea cable.The
One circle chamfering of setting on two sealing rings, 41 outer wall, the side of perfusion production when the setting of this chamfering improves the die sinking of the second sealing ring 41
Just.
When it is implemented, sealing ring 5, clamping cap are arranged between the outer wall of one end of the inner wall and annular end cap 2 of clamping cap 3
Groove 30 is set on the outer wall of 3 one end, and sealing ring 5 is embedded in groove 30.Solution is fitted close between sealing ring 4 and clamping cap 3
Certainly axial seal, and sealing ring 5 is embedded in the setting of groove 30, exactly solves transverse sealing.When have micro water from sealing ring 4 with
When flowing out in gap between clamping cap 3, the setting of sealing ring 5 is exactly second sealing defence line, and a sealing effect more step improves.
Preferably, it is connected between one end of annular end cap 2 and cylinder 1 by welding manner.The simple energy again of such setting
Effectively solve the problems, such as 1 leak of cylinder.
Preferably, sealing ring, which is made, breathes out furan structure.Breathing out furan structure is by sealing ring dimidiation, and general sea cable outer diameter slightly has
It differs, adds long length, the sealing ring of upper and lower two halves is more convenient to be fixed sea cable end and seal.
