Abstract
The utility model provides a natural gas fairing, including inlet piping flange and export pipeline flange, it has the rectification flange to settle between inlet piping flange right side installation face and export pipeline flange left side installation face, it fixes the rectification flange between inlet piping flange and export pipeline flange at the fixing bolt between inlet piping flange and the export pipeline flange to wear the dress, the peripheral system of both ends face has sealed waterline about the rectification flange, on the terminal surface of rectification flange, the system has the through -hole that is outwards become radially arranged by the center. The utility model discloses simple structure, handling ease and installation, strong adaptability, convenient to use has thoroughly solved present natural gas flowmeter import straight tube channel ratio or measure unsafe defect.
Description
Technical field
This utility model belongs to natural gas facility technical field, specifically a kind of natural gas fairing.
Background technology
Commutator is not installed in the effusion meter import of natural gas facility at present, but needs the import straight pipeline of effusion meter to compare
Long thus cause the size of equipment bigger, and for air-flow, some effusion meter steadily requires that relatively strictly air-flow is not
The metering that stably also can cause effusion meter is inaccurate.Present in it, major defect is, unstable air-flow causes effusion meter to read
Number is inaccurate, ultimately causes trade settlement dispute.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of natural gas fairing.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of natural gas fairing, including inlet pipeline flange and outlet conduit flange, on the right side of inlet pipeline flange
It is mounted with rectification flange between installed surface on the left of installed surface and outlet conduit flange, is installed on inlet pipeline flange and outlet conduit
Rectification flange is fixed between inlet pipeline flange and outlet conduit flange by the fixing bolt between flange, left at rectification flange
The periphery of right both ends of the surface is shaped with sealing waterline, on the end face of rectification flange, is shaped with leading to by the arrangement of the outside radial in center
Hole.
And, the 70%-that sectional area sum is rectification flange face area of all through holes on described rectification end face of flange
80%, the diameter d of described through hole are 1st/to four/5th of rectification flange end face diameter D, and the thickness of rectification flange is
/ to three/2nd of described through-hole diameter d.
Advantage of the present utility model and good effect be:
This utility model uses simple in construction, is easy to processing and installation, strong adaptability, easy to use, thoroughly solves mesh
Front natural gas flowmeter import straight pipeline relatively or measures inaccurate defect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view of rectification flange in this utility model.
Detailed description of the invention
Implementing to be further described to this utility model below in conjunction with accompanying drawing, following example are illustrative, are not
Determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of natural gas fairing, as it is shown in figure 1, include inlet pipeline flange 1 and outlet conduit flange 3, in import
It is mounted with rectification flange 2 between installed surface on the left of installed surface and outlet conduit flange on the right side of pipe flange, is installed on inlet pipeline
Fixing bolt 4 between flange and outlet conduit flange rectification flange is fixed on inlet pipeline flange and outlet conduit flange it
Between, the periphery in rectification flange both ends of the surface 6 is shaped with sealing waterline 5, on the end face of rectification flange, is shaped with and is outwards become spoke by center
Penetrating the through hole 7 of shape arrangement, unstable natural gas, by air-flow being become steady after rectification flange, facilitates the meter of downstream flow meter
Amount, and the straight length of downstream flow meter can be reduced, reduce equipment cost.
In of the present utility model being embodied as, on described rectification end face of flange, the sectional area sum of all through holes is rectification
The 70%-80% of end face of flange area, the diameter d of described through hole be rectification flange end face diameter D 1 to four/5th/
One, the thickness of rectification flange is 1st/to three/2nd of described through-hole diameter d, and the rectification flange of this concrete structure exists
Repeatedly practise middle best results.
Operation principle of the present utility model
Natural gas enters from fairing suction flange and is flowed in rectification flange, and rectification flange is natural by instability
Gas, is adjusted to stable natural gas, by fairing outlet(discharge) flange transmission & distribution to natural gas flowmeter or downstream pipe network.
Claims (2)
1. a natural gas fairing, it is characterised in that: include inlet pipeline flange and outlet conduit flange, at inlet pipeline
Be mounted with rectification flange between installed surface on the left of installed surface and outlet conduit flange on the right side of flange, be installed on inlet pipeline flange with
