The flowing of the fluid between block 1 and block 2 is illustrated in greater detail in Fig. 4, it should be understood that between block 2 and block 3,
Between block 1 and bottom and between block 3 and cover piece, the flowing is similar.When these fluids penetrate into each gap I1
During with I2, these fluid sealing relation parts J1 and J2 contact.In the normal operating shown in Fig. 4, these seals J1 and J2 can be grasped
As causing：Seal J1 and J2 prevent fluid from being flowed towards annular space, and without mixing between these fluids.Such as exist
As being schematically shown in the Fig. 4, without flow of fluid into pipe portion 70, therefore detector 80 and alarm 82 are not actuated,
So as to which pipe portion 70 be represented by dashed line.
On the other hand, as shown in figure 5, let us now suppose that inner seal liner J1 is defective.Therefore, occur first-class
Body from gap I1 towards safe space E leakage.It should be noted that due to the seal J2 that still works be present, thus this
One fluid can not be contacted with appearing in the second fluid in the I2 of gap.The first fluid advances then along pipeline 18, and
Advance then along passage 43.
First fluid is then discharged via pipe portion 70 from shell towards detection part 80.Detection part 80 starts alarm 82,
Alarm 82 notifies operator to need the operation of pass hull closure.Operator is further informed the property for the fluid discharged in this way
Matter, to be able to carry out the complete replacement to first seal J1.
As shown in fig. 6, let us now suppose that outside seal J2 is defective, occur second fluid from gap I2 courts
Safe space E the second leakage.It should be noted that due to the seal J1 still to work be present, therefore the second fluid can not
Contacted with appearing in the first fluid in the I1 of gap.
The second fluid then advances via pipeline 18, passage 43 and pipe portion 70 towards detection part.Such as in previous occasion
Like that, operator is apprised of the failure, so as to the use of arrestment, and performs the replacement to second seal J2.
If the leakage of a kind of fluid or one other fluid occurs for the interface between block 3 and cover piece 5 up, flow
Body is discharged along pipeline 38,28 and 18 successively before being discharged via passage 43.If the interface between block 2 and 3
The leakage occurs, then fluid is discharged along pipeline 28 and 18 successively before being discharged via passage 43.Finally, if under
The leakage occurs for the interface between the block 1 of side and bottom 4, then fluid is directly discharged via passage 43.
Pipeline 18,28,38 and passage 43 form the discharge for being suitable for making the potential leakage of fluid proceed to housing exterior
Device.No matter these pipelines and the passage are machine-direction oriented or horizontal orientation, and they are all without leading into flow of fluid
In passage.
