Background technology
Footwear all will detect through certain quality before dispatching from the factory, the test event footwear gas permeability test that wherein relates to the footwear comfortableness does not have the instrument that directly can test at present both at home and abroad, it more is the gas permeability that the gas permeability of indirect utilization test footwear material characterizes product shoes, perhaps cut the certain specification sample from upper of a shoe, the test sample gas permeability characterizes the gas permeability of product shoes, above-mentioned alternative way exists error can not accurately characterize the shortcoming of product shoes gas permeability greatly, and the latter is destructively not accommodate that enterprise tests oneself and the third-party institution identifies property testing for the test product footwear.Development directly test product footwear gas permeability and do not destroy the censorship footwear instrument be the urgent work of shoe-making industry scientific worker.
Gas permeability for footwear material detects, existing leather air permeability tester, use the fixedly clamping device of specification, grip the circular leather sample of specification, the air chamber of clamping device inside connects the teat glass air inlet, and regulating teat glass delivery port and air inlet vertical range is 10mm, thereby the pressure reduction that keeps leather sample both sides 10mm water column, by discharging 100ml water in the test tube, and use stopwatch writing time, calculate the air permeability of unit interval unit are leather.Its shortcoming is that accuracy of instrument is lower, regulates the preparation complexity before the test; The test result error is big, and the different hand-held manual time-keeping errors of tester's reaction speed are big; The data computational processing is big, needs record and manual calculation data; The material sample of regulation shape specification can only be tested, the gas permeability of product shoes can not be tested and characterize.
Also have fabric air-permeability degree tester, it is source of the gas with the blower fan, with clamping device clamping fabric specification sample, blower fan extracts sample one side air, measure air mass flow with gas flowmeter,, write down to see through the fabric sample air mass flow when the fabric pressure differential reaches setting.Its shortcoming is that the blower pressure pulsation is big, air pressure de-stabilising effect test accuracy; The material sample of regulation shape specification can only be tested, the gas permeability of product shoes can not be tested and characterize.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of product shoes air permeability tester, and the permeability that it can accurately characterize into footwear has and measures accurately characteristics easy to use.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of product shoes air permeability tester, comprise gas generating unit 1, the outlet of gas generating unit 1 connects air pressure fixed pressure reducing valve 2, the outlet of air pressure fixed pressure reducing valve 2 is connected to the air hose 44 of welt clamping device 4 by pipeline behind gas flowmeter 3, described welt clamping device 4 comprises one one end standard-sized sheet mouth and the other end has the interior pipe 41 in a centre bore and an inclined to one side hole, on the centre bore of interior pipe 41 air hose 44 is set, on the hole testing tube 45 is set partially, testing tube 45 is connected to pressure tester 5, being socketed with an end outside the interior pipe 41 is bell-mouthed outer tube 43, an end of pipe 41 standard-sized sheet mouths in the horn mouth direction of outer tube 43 is pointed to also has sealing ring 42 between interior pipe 41 and the outer tube 43.
The utility model compared with prior art has the following advantages:
1) directly the test product footwear need not be materialsed and can not destroyed the censorship footwear.
2) can accurately characterize into the gas permeability of footwear.
3) installation cost is low.
4) simple to operate, easy to use.
5) adopt the constant voltage source of the gas, test process is steady, reliable results.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in Figures 1 to 4, the utility model is a kind of product shoes air permeability tester, comprise gas generating unit 1, the outlet of gas generating unit 1 connects, the outlet of air pressure fixed pressure reducing valve 2 is connected to the air hose 44 of welt clamping device 4 by pipeline behind gas flowmeter 3, described welt clamping device 4 comprises one one end standard-sized sheet mouth and the other end has the interior pipe 41 in a centre bore and an inclined to one side hole, on the centre bore of interior pipe 41 air hose 44 is set, on the hole testing tube 45 is set partially, testing tube 45 is connected to pressure tester 5, being socketed with an end outside the interior pipe 41 is bell-mouthed outer tube 43, an end of pipe 41 standard-sized sheet mouths in the horn mouth direction of outer tube 43 is pointed to also has sealing ring 42 between interior pipe 41 and the outer tube 43.
In the present embodiment, gas generating unit 1 adopts the air compressor that has air accumulator, the concrete QSAC-306 type air compressor of selecting, the inner employing of its gas circuit double filtration, the pure drying of gas of output, gas output is after air pressure fixed pressure reducing valve 2, air pressure fixed pressure reducing valve 2 can be selected the T-40 type, the T-41 type, the T-50 type, T-60 type or T-65 type adjustable precision pressure regulator, this a series of pressure regulator with the like product on the current market relatively, service behaviour is because of changes in flow rate, voltage supply changes caused sensitivity and stability and several respects factors such as repeatability the influence of output pressure all is better than like product.Adjusting by air pressure fixed pressure reducing valve 2 can obtain constant air-flow output, the high-precision gas flowmeter 3 of the constant pressure air airflow passes of output obtains the air flow rate size in real time, gas flowmeter 3 can be selected LZ series metal spinner flowmeter for use, its have simple in structure, reliable operation, applied widely, measure characteristics such as accurate, easy for installation, such as the LZD-15 metal-tube rotameter.And then be connected to the air hose 44 of welt clamping device 4 by pipeline, welt clamping device 4 can seal clamping to product shoes system mouth, the testing tube 45 of welt clamping device 4 is connected to high-precision pressure tester 5, and to obtain the footwear external and internal pressure in real time poor, but pressure tester 5 type selecting ZCYB-1000, when pressure differential less than when setting value, reconcile air pressure fixed pressure reducing valve 2 and increase the air mass flow that feeds in the footwear, when pressure differential greater than when setting value, reconcile air pressure fixed pressure reducing valve 2 and reduce to feed the interior air mass flow of footwear, setting value up to constant pressure differential.When footwear external and internal pressure difference constant and simultaneously by certain flow bubbling air in the footwear, the air that this moment, footwear appeared and the air of feeding reach dynamic equilibrium so, read the interior air mass flow of feeding footwear that gas flowmeter 3 is measured, can obtain the Air permenbility of this product shoes under this pressure differential.
The utility model adopts constant pressure air as source of the gas, utilizes unique welt clamping device clamping product shoes, has realized the direct test to product shoes, can not destroy product shoes, and test result is accurately stable.
