Description
Technical field
This application involves industrial pipeline sealing devices, and in particular to a kind of self-locking type industrial pipeline seal plug.
Background technique
Nuclear power station (nuclear power plant) is also known as nuclear power plant, be using nuclear fission (Nuclear Fission) or
Nuclear fusion (Nuclear Fusion) reacts the power plant of discharged energy production electric energy.Nuclear energy hair in business operating at present
Power plant is all to be reacted and generated electricity using nuclear fission.Nuclear power station is generally divided into two parts: utilizing the core of nuclear fission production steam
Island (including reactor assembly and primary Ioops system) and the conventional island (including steam turbine generator system) for utilizing steam-electric power use
Fuel be usually radioactivity heavy metal: uranium, plutonium.
Nuclear power station can substantially be divided into two parts: a part is the nuclear island that steam is generated using nuclear energy, including reactor assembly
With primary Ioops system；Another part is to utilize the conventional island of steam-electric power, including steam turbine generator system.Nuclear fuel is in reactor
The disintegration energy of interior generation mainly occurs in the form of thermal energy.It passes through carrier band and the conversion of coolant, finally uses steam or gas
Drive the power generation of turbine generation unit.All key equipments with hot of nuclear power plant are all mounted on reactor containment vessel workshop
It is interior, it is excessive to limit radioactive substance under loss of-coolant accident (LOCA) or other major accidents.In order to guarantee reactor core nuclear fuel any
In the case of until it is cooling and from burning fusing, nuclear power plant is provided with multinomial security system.
The plug installation environment requirement of the industrial pipeline end part seal of nuclear power station is relatively high, and installation site is narrow, can not
Have dangerous installation connection type by the band spark such as electric welding, in the prior art plug mainly using threaded connection by the way of
It realizes, but the mode poor sealing of the connection that is screwed of the prior art, and connective stability is poor, accomplishes if necessary
Good airproof performance is stablized again, then inconvenient dismounting and change.
Plug, also referred to as pipe cap, headkerchief, tube cover, silently, plug is the one kind for belonging to machanical fastener, as pipe
Track media blocks, the specific purpose tool for preventing medium from outflowing.Common plug is installed on pipe end external screw thread with the pipe fitting of lid plugging,
For closing pipe line, effect is identical as pipe plug, can directly be spun on pipe, not need other pipe fittings.Plug include convex plug,
The design of conical shell, reducer, flat cover and tightening mouth.
Plug involved in industrial pipeline is generally threadedly coupled at present or welded seal, plug are connected through a screw thread or weld
It connects and is fixed on industrial pipeline.It is poor for applicability by screw thread or the plug that connection is welded and fixed, it generally need to be postindustrial to cutting
Pipeline tapping polished, tapping, mantle fiber or welding specific purpose tool can be just sealed.However for field working conditions, there are spaces
In the environment of narrow, fire operation performance difficulty etc. has the limitation of all many conditions, inconvenience carries out tapping and weld job, more inconvenient
In being dismounted for multiple times inspection.
In order to solve this problem, easy-to-dismount seal plug is also used in the prior art, if notification number is CN
The patent of 203809948 U discloses a kind of novel pipeline and plug Hermetical connecting structure, as shown in Figure 1, including needing to connect
Anti-corrosion straight pipeline 5 and plug 1, be equipped with interior cone machine hole inside the connecting pin of the plug 1, interior cone machine hole ecto-entad is gradually
It is narrow, it is socketed tightening nuts 2, flat shim respectively convenient for squeezing seal gasket 3 and anti-corrosion straight pipeline 5, the joint of anti-corrosion straight pipeline 5
4 and cone seal rubber mat 3, the joint of anti-corrosion straight pipeline 5 be taken up in order of priority sequence cover screwing nut 2, flat shim 4 and taper
Seal gasket 3, poroid in cylinder inside the cone seal rubber mat 3, aperture is slightly larger than anticorrosive direct outer diameter tube, and outside is in
With the taper type of interior cone machine hole cooperation, plug 1 is inserted in from the interface of anti-corrosion straight pipeline 5 and by tightening nut 2 and its outer spiral shell
Line is fixedly connected, and tightening nuts 2 are equipped with the internal thread hole cooperated with 1 external screw thread of plug close to 1 one end of plug, and the other end is aperture
Slightly larger than the flat hole of 5 outer diameter of anti-corrosion straight pipeline, outside is in nut type, is tightened by tightening nuts 2, squeezes taper seal gasket 3
It is formed and is sealed with anti-corrosion straight pipeline 5.The novel pipeline and plug Hermetical connecting structure can be installed quickly, be not required to weld；Bolt
Quantity is few, and operation only needs a wrench, and the scene of construction is not got angry, and solderless slag pollutes in pipeline, is particularly suitable for prohibiting fire
Building site, guard system can carry out the cleaning of pipeline, maintenance and replacement at any time.
But the novel pipeline of above-mentioned patent disclosure and the leakproofness of plug Hermetical connecting structure are poor, are connected and fixed fastness
Not strong, though end flat shim 4 has the effect of sealing and anti-skidding, its taper inclined direction reaches direction setting towards pipe, cannot
It is formed self-locking.
