Description
Technical field
The present invention relates to field of mechanical technique, fastening structure in particularly a kind of ring flange.
Background technology
Flange is called ring flange or bead, and flange is the part for making pipe be connected with each other with pipe, is connected to pipe end, flange
Connection refers to be connected with each other the releasable connection as one group of combined sealing structure by flange, pad and bolt three.Flange point spiral shell
Line is connected（Screwed connection）Flange, welded flange and clip flange.Flange connection is because its connection sealing is good, stabilized structure, strong
High, easy to use, low cost and other advantages are spent, are widely used in building trade, urban water supply, boilers and pressure vessel, oil row
The industries such as industry, supply, chemical industry, grocery trade, fire-fighting, pharmaceutical industry, power station, water conservancy, HVAC.
There is the through hole for being easy to connection on flange, but general this through hole is all columned through hole, poor sealing,
And have the phenomenon of shank of bolt protrusion, existing flange fixing structure for the bolt inserted in through hole in fastener cycle
Pad, can be such that keeper does not fasten, if by nut overtorquing, the pressure that flange applies to sealing ring is also bigger,
Ring wear can be aggravated, the service life of sealing ring is reduced；And if nut is not tightened, flange disengagement, sealing ring can be caused
It is extruded the generation for the accident such as carrying out.
The content of the invention
The invention aims to solve the above problems, devise shank of bolt in a kind of fastener cycle and do not protrude, seal
Fastening structure in the good ring flange of performance.
Realize above-mentioned purpose the technical scheme is that, fastening structure in a kind of ring flange, including ring flange, positioning
Part, it is horn-like that the disk body of the ring flange is additionally provided with least one provided with a circle seal groove, on the disk body of the ring flange
Perforate；The upside of the perforate is provided with the sealing ring being engaged with perforate, and sealing ring can be just put into the horn mouth of perforate,
Strengthen sealing property, the upside of the sealing ring is provided with the flat shim being engaged with perforate, flat shim be used for protecting keeper with
Connection between perforate, fastens keeper.
Further, described keeper one end is helicitic texture, and the other end is solid flanges structure.
Further, the keeper is to split nut or bolt.
Further, provided with the helicitic texture being engaged with keeper inside the perforate.
Further, the perforate is uniformly distributed on ring flange disk body on the contrary according to the difference of its quantity.
Bolt or external diameter to split nut are corresponding with the internal diameter of perforate, are screwed into when in use by bolt or to split nut
In perforate of the portion with sealing ring and flat shim, there is no shank of bolt protrusion in fastener cycle, will not leak outside screw thread after fastening, seal
Property it is good, repeatability is strong.
Fastening structure in the ring flange made using technical scheme, its advantage is, 1, ring flange
Disk body is provided with a circle seal groove so that ring flange connection is that sealing is good；2nd, the disk body of ring flange is provided with least one
There are sealing ring and flat shim, simple in construction and good airproof performance in horn-like perforate, perforate；3rd, it is to split nut and bolt
Threaded one end structure, other end solid flanges structure, so either selected in fastening to split nut or bolt all without
Form the phenomenon that shank of bolt is protruded, good seal performance, favorable repeatability.
