Description
Technical field
The utility model relates to a kind of isolated plant that is used for the rubber gas permeability test.
Background technology
At present, the automotive wheel inner tube of a tyre mostly adopts the blended rubber of butyl rubber or butyl rubber and other rubber, these elastomeric materials do not need inflation except that requiring to have high-intensity stretch-proof, the tear-resistant performance, also requiring to have good air-tightness for a long time to guarantee doughnut.The rubber of understanding which kind of composition of which kind of production technology production has better impermeability, need do air-tight test to Related product.General test method is the globality test in the industry now, promptly whole inner tube of a tyre sufficient gas, and connects tensimeter, observes the pressure drop of whole the inner tube of a tyre in a period of time.In addition, also there is not other better mode, but low, the consuming time length of this method of testing precision, it is very inconvenient to operate.
Summary of the invention
In order to solve low, the consuming time length of above-mentioned method of testing precision, the very inconvenient technological deficiency that operates, the purpose of this utility model provide a kind of device that is used for the rubber gas permeability test, and it has characteristics simple in structure, simple to operation.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of device that is used for the rubber gas permeability test, this device comprise frame and the workbench that is fixed on the frame; Upper rack is provided with screw mandrel, and screw mandrel top is provided with the turn handle, and the bottom is fixed with upper pressure seat, and upper pressure seat inside is provided with the gas outlet, and the outer end, gas outlet is provided with and stops cover, and the gas outlet is connected to pressure-display device by the through hole and the pipeline of upper pressure seat inside; Workbench is provided with down pressing seat over against the position of upper pressure seat, down pressing seat inside is provided with air intake opening, air intake opening is connected to the air inlet source by the through hole and the pipeline of down pressing seat inside, and the air inlet source is provided with rain glass, and air intake opening is connected with pressure relief device by the through hole and the pipeline of down pressing seat inside simultaneously.
As preferably, described upper pressure seat is made of briquetting and pedestal, and briquetting is fixedlyed connected with screw mandrel, and pedestal is arranged on the briquetting below, is connected with briquetting is detachable; The through hole of described gas outlet and upper pressure seat inside all is arranged on the pedestal.
As preferably, described pressure-display device is a U type liquid level charactron, is provided with by-pass valve between U type liquid level charactron and the pipeline that the gas outlet is connected, and U type liquid level charactron bottom is connected with the liquid level adjustable pipe.
As preferably, described air intake opening outer end also is provided with and stops cover.
As preferably, the cover that stops of described gas outlet and air intake opening outer end is the screen cloth that mesh diameter is 0.5mm～10mm.
The utility model is owing to adopted above technical scheme, when measuring a circular specimen is put between air intake opening and the gas outlet, press down upper pressure seat by screw mandrel, closed air intake opening and gas outlet, the air inlet source adds certain pressure makes gas penetrate sample under pressure reduction, and gas passes sample and permeates to the gas outlet, low-pressure side volume (V) is certain, so its pressure can increase Δ P by P, as the gas volume that is penetrated into the gas outlet is Δ V, and then the volume of original gas is compressed to V-Δ V.The pressure changes delta P that adopts U type liquid level charactron to monitor the gas outlet can be calculated infiltration capacity Δ V:P * V=(P+ Δ P) * (the V-Δ V) of gas by following formula.The utlity model has characteristics simple in structure, simple to operation.
