Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, manhole mechanism on a kind of high-tension apparatus cylindrical shell, comprise: seal the manhole boss 1 of the annular of fixedly docking with the sidewall of the manhole in equipment barrel, manhole cover 2 is provided with in manhole boss 1, inner end in manhole boss 1 is provided with the back-up ring 12 for stopping manhole cover 2, the outward edge of manhole cover 2 outer end is provided with a ring annular groove 21, is provided with seal washer 3 in circular groove 21, and seal washer 3 can make to form sealing between manhole cover 2 and manhole boss 1 inwall.Because graphite packing has excellent rebound elasticity, the characteristic such as high temperature resistant, high pressure resistant, the seal washer 3 therefore in the present embodiment adopts graphite packing, outside graphite packing, be also provided with Sealing shield ring 31.The inwall being positioned at the manhole boss 1 outside seal washer 3 offers the receiving groove 11 that a circle is inwardly recessed, the tight block of baffle ring 4 is in receiving groove 11 and baffle ring 4 protrudes from receiving groove 11, and baffle ring 4 keeps off and is pressed on Sealing shield ring 31 thus is pressed in circular groove 21 by graphite packing gear.Baffle ring 4 is put together by four pieces of burst baffle rings 41, and the split seam 411 formed between four pieces of burst baffle rings 41 is parallel mutually, and often pair of burst baffle ring 41 is diametrically symmetrical mutually.Baffle ring 4 adopts the effect of burst split structure to be: be convenient to baffle ring 4 and be mounted in receiving groove 11 or split out from receiving groove 11.The block number of burst baffle ring 41 is too much unsuitable, usually be arranged to four pieces comparatively suitable, one piece of baffle ring 4 adopt the structure of four pieces of burst baffle rings 41 split effectively to guarantee the impacting force between baffle ring 4 and sealing gasket 3 is evenly distributed.For the ease of dismounting in the present embodiment, the installation hanger 42 used when every block burst baffle ring 41 is all connected with dismounting, each installation hanger 42 is provided with the tapped through hole 421 for being connected with dismantling device.In addition, for the ease of the dismounting of four pieces of burst baffle rings 41, the sidewall of the manhole boss 1 corresponding with every block burst baffle ring 41 is provided with and dismantles through hole 110, during dismounting burst baffle ring 41, by extracting tool as thin iron staff, stretch to from dismounting through hole 110 and conflict on burst baffle ring 41, then inwardly knock thin iron staff and just burst baffle ring 41 can be pounded out from receiving groove 11, so just can very easily burst baffle ring 41 be taken apart from receiving groove 11.
The inwall of the baffle ring 4 be put together by four pieces of burst baffle rings 41 is arranged with the barrier assembly 13 that four pieces of burst baffle rings 41 can be stoped to deviate from receiving groove 11, as shown in Figure 3, barrier assembly 13 described in the present embodiment comprises: the support ring 5 of a block on baffle ring 4 inwall, support ring 5 offers a gap 51, the support ring 5 at gap 51 two ends is provided with a pair connecting plate 6, be connected with an adjusting nut 8 by an adjusting bolt 7 between a pair connecting plate 6, tightening adjusting nut 8 can make gap 51 spacing reduce, unscrewing adjusting nut 8 can make gap 51 spacing increase.The spacing of gap 51 is larger, support ring 5 larger to the tension force of baffle ring 4; The spacing of gap 51 is less, and the tension force of support ring 5 pairs of baffle rings 4 is less.In actual using process, tension force between support ring 5 and baffle ring 4 inwall can be regulated by regulating the spacing size of gap 51.
The outer end of manhole cover 2 is provided with some bolts hole 22, the outer end cap gear of manhole boss 2 pins down cover plate 9, pin down cover plate 9 is provided with and somely one to one through hole 91 is installed with the bolt hole 22 on manhole cover 2, for the ease of observing the inside of manhole boss 1, pining down in the present embodiment on cover plate 9 and being provided with peep hole 92.In each bolt hole 22, equal screw threads for fastening has a bolt 10, the outer end of every root bolt 10 is all stretched out from the installation through hole 91 of correspondence, bolt 10 outside each installation through hole 91 is provided with locking nut 101, each locking nut 101 all block is pining down on cover plate 9, tightening up each locking nut 101 can make manhole cover 2 seal washer 3 be compressed in advance the inner side keeping off and lean against baffle ring 4, under the effect of equipment barrel internal high pressure, seal washer 3 is sealed compression gear and leans against the inner side of baffle ring 4 thus make mutually to seal between manhole cover 2 and manhole boss 1 by manhole cover 2.Because the effect of bolt 10 and locking nut 101 is only to make to produce pretightening force between manhole cover 2 and baffle ring 4, therefore the diameter of bolt 10 can reduce greatly, the tightening tool that direct use is common, as spanner tightens, this not only greatly facilitates the installation of manhole mechanism, maintenance and dismounting, also greatly reduces that manhole mechanism makes, the cost of installation and maintenance; It is firm that high pressure in equipment barrel to make between the inwall of manhole cover 2 and manhole boss 1 mutually to seal, and the pressure in equipment barrel is larger, sealing effect is better, sealing between manhole cover 2 and manhole boss 1 can not be affected because of the fluctuation of temperature and pressure in equipment barrel, and this just substantially increases the reliability of manhole mechanism sealing.
