Description
Technical field
Field of mechanical technique is the utility model is related to, 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 divides spiral shell
Line connects（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 it is used for the bolt inserted in through hole in fastener cycle, have the phenomenon of shank of bolt protrusion, existing flange fixing structure
Pad, keeper can be made not fasten, if by nut overtorquing, the pressure that flange applies to sealing ring is also bigger,
Ring wear can be aggravated, reduce the service life of sealing ring；And if nut is not tightened, flange can be caused to disengage, sealing ring
It is extruded the generation for the accident such as carrying out.
Utility model content
The purpose of this utility model is to solve the above problems, and devises shank of bolt in a kind of fastener cycle and does not protrude,
Fastening structure in the ring flange of good seal performance.
Realize that above-mentioned purpose the technical solution of the utility model is, fastening structure in a kind of ring flange, including it is ring flange, fixed
Position part, the disk body of the ring flange are provided with a circle seal groove, are additionally provided with the disk body of the ring flange at least one horn-like
Perforate；The upside of the perforate is provided with the sealing ring being engaged with perforate, and sealing ring can just be put into the horn mouth of perforate
In, strengthen sealing property, the upside of the sealing ring is provided with the flat shim being engaged with perforate, and flat shim is used for protecting keeper
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, the helicitic texture being engaged with keeper is provided with 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 is corresponding to the external diameter of split nut and the internal diameter of perforate, is 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, sealing
Property it is good, repeatability is strong.
Fastening structure in the ring flange made using the technical solution of the utility model, its advantage is, 1, flange
The disk body of disk 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 horn-like perforate, there are sealing ring and flat shim, simple in construction and good airproof performance in perforate；3rd, to split nut and bolt
It is threaded one end structure, other end solid flanges structure, so either being selected in fastening to split nut or bolt all
The phenomenon of shank of bolt protrusion, good seal performance, favorable repeatability will not be formed.
