The testing device comprises a lower body and an upper body which are connected through a bolt; a spiral hole is formed in the center position of the upper end face of the upper body; an additionally arranged anti-deformation rotary knob is arranged inside a low-pressure chamber of the upper body, and rotationally arranged in the spiral hole of the upper body; an annular sealing groove is formed in the upper end face of the lower body; the central line of the sealing groove is arranged at the wall of the lower end face of the upper body; paraffin is cast into the sealing groove additionally formed in the internal part of the lower body, so that the air tightness of the testing device is reinforced; the anti-deformation rotary knob can prevent a panel sample from deforming under the action of high-pressure gas when a test panel is put into the testing device. The testing device disclosed by the utility model is reasonable in design structure, simple in structure, low in cost, convenient to operate, and applicable to the air tightness test of the panels with thicknesses.
Description
Technical field
The utility model relates to a kind of sheet material test device for air tightness, relates in particular to the bubble-tight test of plastics and rubber-like sheet material, belongs to testing apparatus class.
Background technology
Traditional test device for air tightness, is mostly to the bubble-tight test of membrane material, and at present, the bubble-tight proving installation of sheet material is perfect not.Due to the deformation quantity difference in the each use procedure of air packing, when when test, permeate filler uncontrollable and measurement with gap between test sheet material, cause the thickness that permeates filler to determine, can make to permeate filler contacts insufficient with sheet material, and plastics and rubber-like sheet material is the easy deformation of sheet material under higher gaseous tension, sheet edge there will be gas permeation to resemble, and traditional test device for air tightness is due to structure and design, and the sheet material that can not complete doing air tightness test does air tightness test.
Summary of the invention
For above-mentioned existing problems, the purpose of this utility model is to provide one can under gases at high pressure condition, prevent test sample plate deformation, the sheet material test device for air tightness again can sealing plate material edge gas oozing out.
To achieve these goals, technical scheme of the present invention is:
Proving installation of the present utility model comprises the lower body and the upper body that are bolted, the upper surface center position of described upper body is provided with threaded hole, the anti-deformation knob of setting up is comprised of screw rod and infiltration plate, screw rod is hollow form, and perforation infiltration plate, screw rod is fixedly connected with infiltration plate, the junction of screw rod and infiltration plate has air hole, anti-deformation knob is arranged in the low-pressure chamber of upper body, its screw rod spinning is in threaded hole, lower body has annular seal groove on upper surface, and the center line of seal groove is positioned at the Bian Bichu of lower surface, upper body.On the infiltration plate of described anti-deformation knob, be provided with equally distributed permeability hole.
Owing to having adopted above technical scheme, the utility model is set up anti-deformation knob and set up seal groove in the lower body of proving installation in proving installation, in the seal groove of setting up in lower body inside, pour into a mould paraffin, strengthened the sealing of proving installation, when test sheet material is put into proving installation and is tested, anti-deformation knob can prevent that sheet coupon height pressure chamber from deformation occurring while passing into gases at high pressure, the gas that sees through sheet coupon can enter the low-pressure chamber in upper body by the permeability hole in the infiltration plate of anti-deformation knob lower end, reduce the measuring error that deformation causes, paraffin in seal groove can prevent that gas from oozing out from sheet edge, by pressure differential method, can realize sheet coupon is done to impermeability detection, proving installation project organization of the present utility model is reasonable, simple in structure, cost is low, easy to operate, be applicable to the air tightness test of various thickness sheet materials.
