Abstract
The utility model one kind conveying anti-corrosion medium pipeline sampling manifold configuration, including conveyance conduit, connected between adjacent two sections of conveyance conduits by bolt through flange, polypropylene annulus is provided between the adjacent flange, annulus cross section size matches with flange sealing surface, the annulus wall, which is provided with to be provided with sampling branch pipe, the sampling branch pipe in through hole vertically with annulus tangent plane, the through hole, is provided with sample cock.The utility model uses and corrosion resistant annulus is installed between the flange of pipeline junction（Polypropylene）, and the method for sampling branch pipe is installed on annulus so that replacing sampling branch pipe is installed more convenient.
Description
Technical field
The utility model is related to chemical field, and in particular to one kind conveying anti-corrosion medium pipeline sampling manifold configuration.
Background technology
The rubber-lined pipe (for example power plant chemistry water process ion-exchanger imports and exports pipeline) that conveying has corrosive liquid must enter
During row sampling, then the sampling branch pipe and flange of same material are welded in line with rubber open front for the carbon steel piping, are served as a contrast through line with rubber unit
After glue processing, with sampling medium just can be obtained after steel flange and the connection of probe tube and sample cock, it is easy to examine.It is above-mentioned to take
Sample branch pipe arrangement, because the Guan Jing for sampling branch pipe is smaller, rubber liner quality is difficult to ensure that, Ananlysis of main cause is by rubber lined pipe
Diameter is very small（Typically less than it is equal to diameter 25mm pipeline）, in big pipeline tapping interface, during line with rubber operation, big pipe with
Line with rubber material between branch pipe（Offset plate 2-3mm is thick）There is whip stitch, line with rubber completes the interface of big pipeline and sampling branch pipe after vulcanization
Easily there is trickle gap（Electric spark is generally also difficult to find when examining）, in the state of corrosive medium is charged, corrosive medium
The interface of big pipe and branch pipe is penetrated into by whip stitch, causes big pipe or branch pipe local corrosion perforation occur（See Fig. 1）, this is just
It is that we are frequently found to cause the corrosion of whole pipeline because of the rubber liner quality problem of sampling nozzle, so as to be overhauled（Remove
There are crack or the bad glue come off, polishing repairing is carried out to corrosion steel pipe, again line with rubber again）Or change whole pipeline（Carry out
New line with rubber whole pipeline with sampling branch pipe is changed）, this not only have impact on by the normal fortune of conveying corrosive medium equipment
OK, and larger service conduits expense is caused, there is certain economic loss.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of conveying anti-corrosion medium pipeline sampling manifold configuration, is taking
Polypropylene annulus is installed between the flange between two segment pipes of sampling point, through hole, and the spiral shell in through hole are set on annulus outer wall
Line connection sampling branch pipe, it is to avoid in conveying corrosive medium pipeline upper shed sampling small pipeline line with rubber operation quality it cannot be guaranteed that
Problem.
The utility model is achieved through the following technical solutions：
Lead between one kind conveying anti-corrosion medium pipeline sampling manifold configuration, including conveyance conduit, adjacent two sections of conveyance conduits
Cross bolt to connect through flange, polypropylene annulus, annulus cross section size and flange are provided between the adjacent flange
Sealing surface matches, and the annulus wall is provided with through hole vertically with annulus tangent plane, the through hole and is provided with sampling branch pipe, institute
State and sample cock is installed on sampling branch pipe.
The utility model further improvement project is that the annulus thickness is 5 ~ 10cm.
The utility model further improvement project is that the through-hole diameter is 2 ~ 4cm.
The utility model further improvement project is that the through hole is connected through a screw thread silk screw thread inside and outside stainless steel hexagonal
The external screw thread of joint, the sampling branch pipe is connected through a screw thread the internal thread of silk nipple inside and outside stainless steel hexagonal.
The utility model further improvement project is that the external contacting surface of silk nipple and annulus is inside and outside the hexagonal
Plane, both are provided with rubber cushion in contact position.
The utility model compared with prior art, has the following advantages that：
First, the utility model uses and corrosion resistant annulus is installed between the flange of pipeline junction（Polypropylene）, and
The method that sampling branch pipe is installed on annulus so that install replacing sampling branch pipe more convenient.
2nd, the utility model is using silk nipple connection annulus and probe tube inside and outside stainless steel stainless steel hexagonal, it is to avoid
There is stripped thread when being directly connected to annulus in probe tube, is fastened while facilitating.
3rd, of the present utility model use is avoided in conveying corrosive medium pipeline upper shed sampling small pipeline line with rubber operation matter
Amount it cannot be guaranteed that the problem of.

Cross-sectional sizes match with the sealing surface of flange 2, and the wall of annulus 3 is provided with through hole 4 vertically with annulus tangent plane, the through hole 4
Inside it is provided with sampling branch pipe 5, the sampling branch pipe 5 and sample cock 6 is installed.The thickness of annulus 3 is 8cm.The through hole 4
A diameter of 3cm.The through hole 4 is connected through a screw thread the external screw thread of silk nipple 7 inside and outside stainless steel hexagonal, the sampling branch pipe
6 are connected through a screw thread the internal thread of silk nipple 7 inside and outside stainless steel hexagonal.Silk nipple 7 and annulus 3 inside and outside the hexagonal
External contacting surface be plane, both are provided with rubber cushion in contact position.
The conveying anti-corrosion medium pipeline pipeline pressure that normally uses of sampling manifold configuration described in Fig. 2 0.6Mpa with
Under, if to be used in the higher pipeline of pressure, high pressure resistant, corrosion-resistant material can be selected to make annulus.
