Description

One kind is got rusty bolt more changing device online
Technical field
The present invention relates to the flange pipe interconnection technique field of fluid conveying, more particularly to one kind bolt that gets rusty is replaced online Device.
Background technology
It is every that the union piece for being bolted while closing is used in two planar perimeters, generally referred to as " flange ", because And flange has obtained extensive hair application in various fields.Flanged joint is exactly that two pipelines are first individually fixed at a ring flange On, flange gasket is then added between two ring flanges, and finally two ring flanges are tensed with bolt makes it combine closely A kind of dismountable connector.
Due in long-time service or exposure and the air of bolt or nut, bolt or nut are by phenomenon of getting rusty.Spiral shell The reason for bolt or nut get rusty is as follows:1)Electrochemical corrosion, bolt or nut surface stockpile the powder containing other metallic elements The attachment of dirt or disparate metals particle, in wet air, the condensed water between attachment and stainless steel, is linked to be one by the two A micro cell, has triggered electrochemical reaction, and protective film is destroyed, so that chemical attack occurs for bolt;2)Organic acid corrosion, Bolt or nut surface are stained with machine thing juice, such as melon dish, noodle soup, in the case of having water oxygen, form organic acid, for a long time then Corrosion of the organic acid to metal surface;3)Chemical attack:In having the air of pollution, such as containing a large amount of sulfide, carbonoxide, oxygen Change air of nitrogen etc., to the cold condensate, form sulfuric acid, nitric acid, acetate solution point, cause chemical attack.
Since the corrosion of bolt or nut will reduce its intensity and service life, and influence flanged joint sealing performance, Security performance, unfailing performance, so that there are great security risk for the bolt to get rusty.For ensure flanged joint security and can By property, then need to replace the bolt to get rusty, however, having flange since the bolt that gets rusty tenses, flanged joint has pipeline;It is if right Get rusty bolt or nut is replaced, then need to carry out stopping transportation operation to the fluid in pipe using the prior art, after stopping transportation operation again To getting rusty, bolt is replaced.
But there are the following problems for the prior art:Due to needing stopping transportation to replace bolt, thus the normal of pipe downstream will be produced Tremendous influence is caused, and causes huge economic loss;Further, since stopping transportation is replaced, will also it increase bolt replacement of getting rusty Operating time.Therefore, it is the bolt or nut that get rusty on quick-replaceable flange pipe, there is an urgent need to a kind of online bolt with pressure Or nut more changing device.
The content of the invention
In order to overcome the disadvantages mentioned above of existing weaponry and equipment, get rusty bolt more changing device online it is an object of the invention to one kind, The device can realize that flange gets rusty with pressure, the online replacement of bolt, nut, and then realize the screw bolt and nut of flanged joint pipeline Quick-replaceable.
In order to achieve the above object, the technical proposal of the invention is realized in this way:
One kind is got rusty bolt more changing device online, including upper compression ring 1, compress gasket 2, lower compression ring 3, it is characterized in that:Upper pressure Tight that compress gasket 2 is provided between ring 1 and lower compression ring 3, upper compression ring 1 connects into one with lower compression ring 3 by turnbuckle 15 Body;
The upper compression ring 1 includes upper left compression ring 11 and upper right compression ring 12;Upper left compression ring 11 is with upper right compression ring 12 Bilateral symmetry;Upper left compression ring 11 is in semi-annular shape, and upper left compression ring 11 forms complete annulus with upper right compression ring 12; The upper surface of upper left compression ring 11 is designed with trapezoidal projected claw 13, and projected claw 13 extends radially and upper with upper flange 41 End contact;Rectangle cavity 14 is designed between projected claw 13 and projected claw 13;The upper surface design of projected claw 13 is perforative to be had Circular through hole, turnbuckle 15 make left compression ring 11 overlap simultaneously with bottom left compression ring 31 through left side circular through hole 17 Bolt is formed to be fastenedly connected;Turnbuckle 15 makes left compression ring 11 be overlapped with bottom right compression ring 32 through right side circular through hole 18 Together and form bolt and be fastenedly connected;
The compress gasket 2 is installed between compression ring 1 and lower compression ring 3;2 outer surface of compress gasket is arc-shaped, is compressed The inner surface of gasket 2 is provided with rectangular recess 21, and transition arc 22 is designed between rectangular recess 21;There is turnbuckle in rectangular channel 15 pass through;
The lower compression ring 3 includes bottom left compression ring 31 and bottom right compression ring 32, and bottom left compression ring 31 is with bottom right compression ring 32 Bilateral symmetry, bottom left compression ring 31 and upper left compression ring 11 are structure symmetrical above and below;Bottom left compression ring 31 is by tensing spiral shell Bolt 15 is connected with left compression ring 11 and upper right compression ring 12;Bottom right compression ring 32 is connected with upper left compression by turnbuckle 15 Ring 11 and upper right compression ring 12.
Compared with the prior art, the beneficial effects of the invention are as follows:(1)Get rusty bolt, nut can it is with pressure it is online replace so that The replacement operation of bolt of making to get rusty will not impact the normal production of pipe downstream;(2)Get rusty the replacement nothing of bolt, nut Stopping transportation operation is needed, because the time of replacement operation can be shortened.(3)Full mechanical, the bolt that gets rusty replacement with pressure are safe and reliable; (4)It is simple in structure, it is easy to manufacture, and then the production of the present apparatus, manufacture cost can be reduced.
