Description
Technical field
It the utility model is related to a kind of test fixture, and in particular to a kind of fuel nozzle rotary fluid branch pipe flow rate test folder
Tool.
Background technology
In industry gas turbine structure, the rotary fluid flow value in its fuel nozzle is important in gas turbine work
One parameter, it is necessary to be measured to its inner eddy flow body flow value before fuel nozzle is formally assembled into gas turbine, due to
Nozzle rotary fluid has multiple manifold configurations, needs to distinguish manufacturing flange pipe fitting one one according to branch pipe size when being tested
Individual installation test, not only wastes time and energy, and installation is repeated several times and gas leakage risk be present, and operating efficiency is low.
Utility model content
Purpose of utility model：The utility model is in order to solve the deficiencies in the prior art, there is provided a kind of fuel nozzle eddy flow
Body branch pipe flow rate test fixture, multiple branch pipe flows are realized by designing Special-shaped flange while are measured, reduce installation number, improve
Operating efficiency, while reduce gas leakage risk.
The technical solution adopted in the utility model：A kind of fuel nozzle rotary fluid branch pipe flow rate test fixture, including abnormal shape
Flange, multiple branch's curved tubes, there are multiple air inlets on the Special-shaped flange, described branch's curved tube one end is welded with circular method
Orchid, the other end are welded on the air inlet of correspondingly-sized size, and test fixture is fixed by Special-shaped flange and fuel nozzle, and is entered
The gas outlet of gas port and fuel nozzle corresponds, and multiple branches curved tube is connected realization with flow testing device by circular flange
Disposable multi-pipeline flow rate test.
Preferably, have bending section among branch's curved tube, the bending section is two-way 90 ° of bendings, bending length
For 100-120mm.
Preferably, the Special-shaped flange shape is consistent with the shape of fuel nozzle mounting surface.
Beneficial effect：A kind of fuel nozzle rotary fluid branch pipe flow rate test fixture disclosed in the utility model, passes through one
Individual Special-shaped flange and multiple branch's curved tubes coordinate the disposable measurement for realizing the multiple pipeline inward turning fluid flows of gas nozzle, will be different
The structure of type flange is designed to consistent with fuel nozzle configuration, it is ensured that seal during installation, the possibility of leakage is reduced, this
Outer disposable multi-pipeline measurement reduces installation and changes number, improves test jobs efficiency, while reduces test pipeline
Wear intensity, improve its service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of the utility model embodiment is carried out clear, complete
Description.
As shown in figure 1, a kind of fuel nozzle rotary fluid branch pipe flow rate test fixture disclosed in the utility model, is arranged on
On the fuel nozzle of gas turbine, branch testing is carried out to the flow of the rotary fluid in its each pipeline, concrete structure includes different
Type flange 1, wherein multiple branch's curved tubes 2 and circular flange 3, the contact surface of its planform of Special-shaped flange 1 and fuel nozzle
Shape is consistent, and its surface offers multiple air inlets, and a pair of the position of the air inlet and the gas outlet position 1 of fuel nozzle
Should, after Special-shaped flange and fuel nozzle are installed, the rotary fluid that air inlet and gas outlet be overlapped to be ensured in fuel nozzle is straight
Tap into Special-shaped flange.
The circular flange welded and installed is welded on Special-shaped flange in the end of branch's curved tube, branch's curved tube other end
On the air inlet of correspondingly-sized size so that rotary fluid enters each branch's curved tube, realizes multi-pipeline flow while tests.
There is bending section 4, the bending angle of the bending section is two-way 90 °, and bending length is among branch's curved tube
100-120mm, the setting of bending section enables three flanges are coplanar to arrange, while passes through air-flow smoothness.
Technology contents and technical characteristic of the present utility model are had revealed that as above, but those skilled in the art still may be used
A variety of replacements and modification without departing substantially from the utility model spirit can be made based on teaching of the present utility model and announcement, therefore, this
Utility model protection scope should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model
And modification, and covered by present patent application claim.
