Abstract
The invention discloses a kind of blind flange, including: it is fixed on the flange circle of pipe end and solid ring flange body, there is on a week of described solid ring flange body and flange circle the bolt hole of multiple correspondence, there is on described flange circle multiple sealing grooved ring, the cross section indentation of the plurality of sealing grooved ring, there is on described solid flange multiple sealing bulge loop, the cross section indentation of the plurality of sealing bulge loop.By the way, present configuration advantages of simple, there is preferable sealing property.
Description
Technical field
The present invention relates to flange technical field, particularly relate to a kind of blind flange.
Background technology
Flange is a kind of fastening means, and Flange joint refers to be connected with each other as one group by flange, pad and bolt three
The releasable connection of combined sealing structure.Flange divides threaded (screwed connection) flange, welded flange and clip flange.Flange is even
Connect because its connection sealing is good, stabilized structure, intensity are high, easy to use, low cost and other advantages, be widely used in building row
Industry, urban water supply, boilers and pressure vessel, petroleum industry, supply, chemical industry, grocery trade, fire-fighting, pharmaceutical industry, power station, water
The industries such as profit, HVAC.Blind flange is the one in flange, is usually and is used for blocking pipe end, and existing blind flange need
Improve.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of blind flange, simple and reasonable, has preferably sealing
Performance.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of blind flange, including: Gu

Accompanying drawing, wherein:
Fig. 1 is the structural representation of blind flange one of the present invention preferred embodiment.
In accompanying drawing, the labelling of each parts is as follows: 1, flange circle, 2, solid ring flange body, 3, seal grooved ring, 4, seal convex
Ring.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiments that technical staff is obtained under not making creative work premise, broadly fall into the model of present invention protection
Enclose.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of blind flange, including: being fixed on the flange circle 1 of pipe end and solid ring flange body 2, described solid ring flange is originally
There is on a week of body and flange circle the bolt hole of multiple correspondence, described flange circle has multiple sealing grooved ring 3, the plurality of
Seal the cross section indentation of grooved ring, described solid flange has multiple sealing bulge loop 4, the horizontal stroke of the plurality of sealing bulge loop
Cross section indentation, during use, seals grooved ring 3 and sealing bulge loop 4 matches, extrude pad, good seal performance.
Preferably, described sealing grooved ring has five, the different diameters between the most adjacent two 2 millimeters.
Preferably, described sealing bulge loop has five, the different diameters between the most adjacent two 2 millimeters.
Preferably, it is provided with asbestos washer between described flange circle and solid ring flange body.
The invention has the beneficial effects as follows: blind flange of the present invention, simple and reasonable, there is preferable sealing property.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology neck
Territory, is the most in like manner included in the scope of patent protection of the present invention.
