Embodiment
The present invention is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the manhole mechanism on a kind of high-tension apparatus cylinder, including：With the manhole in equipment barrel
The annular manhole boss 1 of the fixed docking of side wall sealing, is provided with manhole cover 2 in manhole boss 1, the inner end in manhole boss 1
The back-up ring 12 for stopping manhole cover 2 is provided with, the outward flange of the outer end of manhole cover 2 is provided with a ring annular groove 21, annular groove 21
In be provided with seal washer 3, seal washer 3 can make to form sealing between manhole cover 2 and the inwall of manhole boss 1.Due to graphite plate
Root has the characteristic such as excellent resilience, high temperature resistant, high pressure resistant, therefore the seal washer 3 in the present embodiment uses graphite packing,
Sealing shield ring 31 is additionally provided with the outside of graphite packing.One is offered on the inwall of the manhole boss 1 in the outside of seal washer 3
The holding tank 11 being inwardly recessed is enclosed, 4 close block of baffle ring is in holding tank 11 and baffle ring 4 protrudes from holding tank 11, and baffle ring 4 is kept off
It is pressed on Sealing shield ring 31 so as to which graphite packing gear is pressed in annular groove 21.Baffle ring 4 is put together by four pieces of burst baffle rings 41,
The split seam 411 formed between four pieces of burst baffle rings 41 is mutually parallel, and each pair burst baffle ring 41 diametrically is mutually right
Claim.Baffle ring 4 is using the effect of burst split structure：It is easy to baffle ring 4 to be attached in holding tank 11 or torn open from holding tank 11
Go out.The block number of burst baffle ring 41 should not be excessive, is usually disposed as four pieces relatively suitably, and one piece of baffle ring 4 uses four pieces of burst baffle rings 41
The structure of split can effectively ensure that the thrust between baffle ring 4 and sealing gasket 3 is evenly distributed.For the ease of tearing open in the present embodiment
Unload, the installation hanger 42 used when being respectively connected with dismounting on every piece of burst baffle ring 41, each install is provided with use on hanger 42
In the tapped through hole 421 being connected with dismantling device.In addition, for the ease of the dismounting of four pieces of burst baffle rings 41, with every piece of burst
Dismounting through hole 110 is provided with corresponding to baffle ring 41 in the side wall of manhole boss 1, when dismantling burst baffle ring 41, by extracting tool
Such as thin iron staff, conflict is stretched to from dismounting through hole 110 on burst baffle ring 41, then inwardly tapping thin iron staff just can be by burst
Baffle ring 41 knocks out from holding tank 11, very easily can thus take apart burst baffle ring 41 from holding tank 11.
Being arranged with the inwall for the baffle ring 4 being put together by four pieces of burst baffle rings 41 can prevent four pieces of burst baffle rings 41 calm
The barrier assembly 13 of the interior abjection of groove 11 of receiving, as shown in figure 3, the barrier assembly 13 described in the present embodiment includes：One block exists
Support ring 5 on the inwall of baffle ring 4, a gap 51 is offered in support ring 5, one is provided with the support ring 5 at the both ends of gap 51
To connecting plate 6, it is connected between a pair of connecting plates 6 by a regulating bolt 7 with an adjusting nut 8, tightens adjusting nut 8
The spacing of gap 51 can be reduced, the increase of the spacing of gap 51 can be caused by unscrewing adjusting nut 8.The spacing of gap 51 is bigger, support
The tensile force to baffle ring 4 of ring 5 is bigger；The spacing of gap 51 is smaller, and support ring 5 is to the tensile force of baffle ring 4 with regard to smaller.It is actual
, can be by the tensile force that adjusts the spacing size of gap 51 to adjust between support ring 5 and the inwall of baffle ring 4 during use.
The outer end of manhole cover 2 is provided with some bolts hole 22, and the outer end cap gear of manhole boss 2 pins down cover plate 9, pins down lid
Some one-to-one installation through-holes 91 of bolt hole 22 with manhole cover 2 are provided with plate 9, for the ease of observing manhole boss
1 inside, pin down in the present embodiment and peep hole 92 is provided with cover plate 9.Screw threads for fastening has a spiral shell in each bolt hole 22
Bolt 10, the outer end of every bolt 10 are stretched out from corresponding installation through-hole 91, on the bolt 10 outside each installation through-hole 91
Locking nut 101 is provided with, on cover plate 9 is pind down, tightening up each locking nut 101 can make each 101 equal block of locking nut
Manhole cover 2 compresses seal washer 3 inner side that gear leans against baffle ring 4, in the presence of equipment barrel internal high pressure, manhole cover in advance
Seal washer 3 is sealed compression gear by 2 leans against the inner side of baffle ring 4 so that being sealed against each other between manhole cover 2 and manhole boss 1.
Make to produce pretightning force between manhole cover 2 and baffle ring 4 because the effect of bolt 10 and locking nut 101 is only that, therefore bolt 10
Diameter can greatly reduce, directly tightened using common tightening tool, such as spanner, this not only greatly facilitates manhole
Installation, maintenance and the dismounting of mechanism, have been greatly reduced the cost of manhole mechanism making, installation and maintenance；In equipment barrel
It is firm that high pressure to seal against each other between the inwall of manhole cover 2 and manhole boss 1, and the pressure in equipment barrel is bigger, close
Seal effect it is better, between manhole cover 2 and manhole boss 1 sealing will not because of temperature and pressure in equipment barrel fluctuation and
It is affected, this has been considerably improved the reliability of manhole mechanism sealing.
