Description
One, technical field
The utility model relates to a kind of air-flow ST, particularly a kind of telescopic air-flow ST.
Two, background technology
The air-flow ST of general sampling formula gas flow measurement system is the roughly suitable device of size and dimension of measured object (for example heat interchanger) xsect in a kind of and the air channel; Because size, shape and the position of measured object vary; Such air-flow ST is because its sampling area and highly all be changeless; Thereby can not adapt to various measured objects fully, and can bring measuring error, cause to detect and lose standard.
Three, summary of the invention
The purpose of the utility model provides a kind of telescopic air-flow ST, it has, and simple in structure, adaptive faculty is strong, the sampling area and highly all scalable, can guarantee measurement result characteristics accurately and reliably.
The utility model addresses the above problem through following technical scheme: a kind of telescopic air-flow ST; By vertical airduct, laterally the holder of sliding seat, knurlied knob bolt and the lifting pedestal of airduct, band, lengthening airduct, plug, shade tube, lifting pedestal is assembled; The crosswind face of said vertical airduct has a plurality of mounting holes; Laterally airduct is horizontally through vertical airduct from these mounting holes; Laterally the vent of airduct crosswind face center is in the inside of vertical airduct; Vertically link together between the sliding seat of airduct and lifting pedestal and be inserted in the holder of lifting pedestal, the back of the sliding seat of lifting pedestal has one group to be used for spacing knurlied knob bolt, and it is the lengthening airduct that has breach that said horizontal airduct is provided with an end; Said vertical airduct or horizontal airduct also are provided with the shade tube and the plug of end sealing, and the windward side of said vertical airduct, horizontal airduct and lengthening airduct is provided with a plurality of thief holes.
Said horizontal airduct is 90 ° mutually with vertical airduct.
The mounting hole diameter of said vertical airduct is identical with the external diameter of horizontal airduct.
The holder of said lifting pedestal is inverse-T-shaped.
The sliding seat of said lifting pedestal is one to have the square tube of a plurality of spacing holes and be inserted in the holder of lifting pedestal.
Bundle through band between the sliding seat of said vertical airduct and lifting pedestal.
Said vertical airduct, horizontal airduct and lengthening airduct are pipe, and the uniform thief hole in a plurality of intervals that are arranged in a linear is arranged on the windward side.
One end of said lengthening airduct is the sleeve that can be inserted in horizontal airduct that has breach.
During use, if the size decreases of measured object can be taken the plug of horizontal airduct, be inserted in the shade tube, block a part of thief hole, the sampling area diminishes.If it is big that the size of measured object becomes, can be inserted in the lengthening airduct at the beam wind tube end, to increase thief hole quantity, the sampling area becomes big.Change like the measured object height and position, can adapt to through the height of regulating lifting pedestal.
The beneficial effect that the utility model reaches is:
Thief hole quantity can increase arbitrarily or reduce, and height can be regulated arbitrarily, makes the dynamic adaptive testing needs of sampling area ability of air-flow ST, no longer receives the restriction of size, shape and the position of measured object, and the inaccurate errors caused of taking a sample is reduced to minimum.And it is simple in structure, easy for installation.

Being labeled as among Fig. 3: thief hole 10, mounting hole 11, air vent 12.
Five, embodiment
Below through accompanying drawing and embodiment the technology of the utility model is constituted and to do further explain.
As shown in Figure 1; The said telescopic air-flow ST of the utility model is by vertical airduct 1, laterally the holder 9 of sliding seat 7, knurlied knob bolt 8 and the lifting pedestal of airduct 2, band 3, lengthening airduct 4, plug 5, shade tube 6, lifting pedestal is assembled.
The crosswind face of said vertical airduct 1 has a plurality of mounting holes 11; The diameter of mounting hole 11 is identical with the external diameter of horizontal airduct 2; Laterally airduct 2 is horizontally through vertical airduct 1 in these mounting holes 11; Both are 90 degree mutually, and all thief holes 10 are with plug 5 all towards the windward side at horizontal airduct 2 two ends and vertical airduct 1 upper end.
According to the size of measured object, the difference of shape, can the plug on the horizontal airduct 2 be replaced by shade tube 6, adjust its degree of depth of being inserted in horizontal airduct 2 to dwindle the sampling area; Also can be laterally being inserted in lengthening airduct 4 between airduct 2 and the plug 5, to increase the sampling area.On lengthening airduct 4, can also use shade tube 6 adjustment sampling areas.
As shown in Figure 2; The holder 9 of lifting pedestal is inverse-T-shaped; The sliding seat 7 of lifting pedestal is inserted in the holder 9 of lifting pedestal; Sliding seat 7 backs of lifting pedestal have one group to be used for spacing knurlied knob bolt 8, vertically are fixed together through the mode of band 3 with binding between the sliding seat 7 of airduct 1 and lifting pedestal.
As shown in Figure 3; The horizontal airduct 2 of each root all is horizontally through through the mounting hole 11 on the vertical airduct 1 crosswind face; Laterally the air vent 12 of airduct 2 crosswind faces center is in vertical airduct 1 inside; The holder 9 of lifting pedestal has a plurality of screws, and the screw of holder 9 of spacing hole and lifting pedestal that knurlied knob bolt 8 passes sliding seat 7 backs of lifting pedestal tightens.
According to the difference of the height of measured object, can unclamp knurlied knob bolt 8, the relative height between the sliding seat 7 of manual adjustments lifting pedestal and the holder 9 of lifting pedestal, to raise or to reduce the sample position, tightening knurlied knob bolt 8 at last again can be spacing.
