Abstract
A kind of threader that the present invention is provided, including threading mechanism and the seal that is filled in the threading mechanism；Wherein described threading mechanism includes：Mounting seat；Mounting post, one end of the mounting post is arranged in the mounting seat；Threading hole, through being arranged in the mounting seat and the mounting post, the inwall of the threading hole is to be obliquely installed to the threading hole.The threading hole is truncated cone-shaped.The seal is fluid sealant.Screw thread is provided with the outside of the mounting post.Compared with prior art, beneficial effects of the present invention are as follows：Cable can be caused external container from pressure vessel inside through wall, while ensureing the sealing at threading in the case of there is certain high temperature, high pressure inside pressure vessel.
Description
Technical field
The present invention relates to a kind of lead sealing equipment, the threading of specifically a kind of holding wire power line crossing high-pressure wall is filled
Put.
Background technology
In PWR nuclear power plant occurs major accident process, under the zirconium alloy cladding high temperature of reactor core part of fuel
A large amount of hydrogen can be all produced with vapor reaction and reactor core fused mass and concrete reaction.Hydrogen is in containment
In transport process, mix with water vapour with the air in shell, burning mixture can be formed in containment segment space.Certain
Under the conditions of, temperature, pressure load can be formed after mixed gas burning in container, and it is quick-fried that hydrogen gas mixture once occurs
Combustion even blast will also jeopardize the integrality of containment, cause the serious consequence that radioactive substance leaks.Therefore, to major accident
The research of hydrogen behavior and mitigation strategy in lower containment must obtain due attention.
For the behavior of hydrogen and mitigation strategy in research safety shell, effective method is the pressure in some scale at present
In container to the detonation of the Gas Mixtures Containing Hydrogen of different component, compound study.In order to directly reflect hydrogen detonation, be combined
When characteristic, it is necessary to be measured to signals such as the temperature in pressure vessel, pressure.In test, by thermocouple, pressure probe
Etc. detector arrangement inside pressure vessel, signal acquisition is carried out outside pressure vessel.Therefore the technique for needing design certain,
The sealing that associated cable draws guarantee pressure vessel simultaneously through pressure vessel wall is not destroyed.
The content of the invention
For defect of the prior art, preferably transmission of electricity and signal transmission can be reached it is an object of the invention to provide one kind
Effect, and the threader of the sealing property of pressure-resistant tank body is effectively ensured.
In order to solve the above technical problems, a kind of threader that the present invention is provided, including threading mechanism and it is filled in institute
State the seal in threading mechanism；Wherein described threading mechanism includes：Mounting seat；Mounting post, one end of the mounting post is set
In the mounting seat；Threading hole, the threading hole through being arranged in the mounting seat and the mounting post, the threading hole
Inwall to be obliquely installed.
Preferably, the threading hole is truncated cone-shaped.
Preferably, the seal is fluid sealant.
Preferably, it is provided with screw thread on the outside of the mounting post.
Compared with prior art, beneficial effects of the present invention are as follows：Cable can be drawn from pressure vessel inside through wall
To external container, while ensureing the sealing at threading in the case of there is certain high temperature, high pressure inside pressure vessel.
Brief description of the drawings
The detailed description made to non-limiting example with reference to the following drawings by reading, further feature mesh of the invention
And advantage will become more apparent upon.
Fig. 1 is threader structural representation of the present invention.
In figure：
1- mounting seat 2- mounting post 3- threading holes
Specific embodiment
Using specific embodiment, the present invention is described in detail below.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that to the ordinary skill of this area
For personnel, without departing from the inventive concept of the premise, some changes and improvements can also be made.These belong to the present invention
Protection domain.
The present invention proposes a kind of acrossing schemes simple and easy to apply, and the customization pipeline and pressure-resistant circuit of costliness are not used, adopts
With general holding wire and power line.
As shown in figure 1, a kind of threader that the present invention is provided, mainly by threading mechanism (including mounting seat 1 and mounting post
2), fluid sealant (not shown) composition.Wherein threading mechanism select general pressure-resistant screw, the line footpath passed through as required,
Screw is drilled, threading hole 3 forms interior big outer small truncated cone-shaped, can so effectively utilize autoclave inside and outside differential pressure to add
Strong sealing effectiveness；Fluid sealant (not shown) needs mobility preferable.
During installation, 1, ensure that holding wire/power line surface cleaning is dried, cable is passed through into threading hole 3；2nd, by fluid sealant
(not shown) is poured into threading hole 3, waits the solidification of fluid sealant (not shown).It is solid to ensure because threading hole 3 is more long
Change effect, by the way of repeatedly pouring into, single pours into a small amount of fluid sealant (not shown), after waiting it to be fully cured again
Pour into, until being completely filled with fluid sealant (not shown) in threading hole 3 and being fully cured.Cable is should be noted during encapsulating
The wall of threading hole 3 should not be touched, and the cable for passing through be more than one when cable between will not contact with each other；3rd, by threader
Structure is screwed onto on pressure vessel wall and shifts to an earlier date on ready screw thread.For ensure sealing effectiveness, it is necessary to by the radius of threading hole 3 it is larger one
It is placed on pressure upper side.
Specific embodiment of the invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can within the scope of the claims make a variety of changes or change, this not shadow
Sound substance of the invention.In the case where not conflicting, feature in embodiments herein and embodiment can any phase
Mutually combination.
