Abstract
The invention discloses a detection device and detection method for gas leakage of a rubber product. The detection device is characterized in that a sleeve body and a shell body are included, a rubber sleeve and one-way valves are arranged in the sleeve body, the sleeve body is sleeved with the shell body, a sensor and a light emitting tube connected with the sensor are arranged at the top of the shell body, more than two gas holes are formed in the top of the sleeve body, the one-way valves are arranged in the rubber sleeve and at the bottom of the sleeve body respectively, and a cavity which is used for containing the detected rubber product and has gas tightness after being inflated is formed between the sleeve body and the shell body. The detection device and detection method have the advantages that the structure is simple, the operation is easy and convenient, the sleeve body is arranged in the rubber product, the sleeve body is filled with a certain amount of detection gas, whether the rubber product is qualified or not is judged by detecting whether the special gas leakage happens or not through the sensor, a tiny hole in the rubber product can be detected, the aim of detecting gas tightness qualification of the rubber product fast and efficiently is achieved, an overflow valve is arranged at the top of the shell body, the gas is exhausted when pressure generated by the detection gas reaches a threshold value standard, and the situation that the pressure is too large and the device is damaged is avoided.
Description
Technical field
The present invention relates to the detection of rubber, specifically a kind of rubber gas leak detection device and detection method.
Background technology
At present, due to a variety of causes of rubber in manufacture process, may cause in rubber existing very small hole, the existence of these apertures can make that rubber leaks air, underproof situation, can not meet the demand in some special airtight occasions.
Summary of the invention
The object of the invention is for overcoming the deficiencies in the prior art, and provide a kind of simple in structure, rubber gas leak detection device and detection method easy and simple to handle.
The technical scheme that realizes the object of the invention is:
A kind of rubber gas leak detection device, in comprising, be provided with the body of gum cover and retaining valve and be set in external housing, be provided with sensor and the luminotron being connected with sensor in case top, body top is provided with 2 above pores, retaining valve is separately positioned in gum cover and body bottom, between body and housing, after inflation, is a bubble-tight cavity.
Also be provided with surplus valve in case top, the threshold values of surplus valve is greater than 1.05 atmospheric pressure of atmospheric pressure.
Described retaining valve is 3.
Described gum cover is interior airtight annulus gum cover.
Described body is plastics inner sleeve.
Described housing is hard shell.
Described sensor is special gas sensor, is prior art.
Rubber leak detection method of the present invention, comprises the steps:
(1) will be detected rubber and be placed between plastics inner sleeve and hard shell, in plastics, be placed in rubber;
(2) by being filled with gas in the inside airtight annulus gum cover of retaining valve, plastics inner sleeve and detected rubber are fixed on hard shell, and there is certain impermeability;
(3) be filled with and detect gas and air by retaining valve respectively, the mixed gas that detects gas and air enters in detected rubber by the pore at plastics inner sleeve top, detect the leakage that whether has special gas by sensor, and whether the color of observing the luminotron on sensor change, judge that whether rubber is qualified.
The invention has the beneficial effects as follows: simple in structure, easy and simple to handle, by place a body in rubber, and be filled with a certain amount of detection gas in body, utilize sensor to detect the leakage that whether has special gas, judge that whether rubber is qualified, can detect hole very small on rubber, reach the object of the airtight qualification of detection rubber rapidly and efficiently, case top is provided with surplus valve, in the time that the pressure of detection γ-ray emission reaches threshold values standard, and Exhaust Gas, avoid pressure excessive, damage device.
Accompanying drawing explanation
Fig. 1 is the structural representation of rubber gas leak detection device of the present invention;
Fig. 2 is the fundamental diagram of rubber gas leak detection device of the present invention.
In figure: 1. hard shell 2. sensor 3. surplus valve 4. plastics inner sleeve 5. annulus gum cover 6. the 1st retaining valve 7. the 2nd retaining valve 8. the 3rd retaining valve 9. pore 10. rubbers.
Embodiment
With reference to Fig. 1, a kind of rubber gas leak detection device of the present invention, by hard shell 1, be arranged on the plastics inner sleeve 4 in hard shell 1, be arranged on the surplus valve 3 at hard shell 1 top, special gas sensor 2 and the luminotron composition being connected with sensor 2, plastics inner sleeve 4 bottoms are provided with the annulus gum cover 5 of built-in the 1st retaining valve 6, the 2nd retaining valve 7 and the 3rd retaining valve 8, plastics inner sleeve 4 tops are provided with 6 pores 9, between plastics body 4 and hard shell 1, be detected the cavity of rubber 10 for placement, this cavity is by the 1st retaining valve 6, after the 2nd retaining valve 7 and the 3rd retaining valve 8 inflations, there is certain impermeability, surplus valve 3 is for detection of the detection gas as hydrogen, ammonia etc., the threshold values of surplus valve 3 is slightly approximately 1.05 atmospheric pressure than atmospheric pressure, in the time that the pressure of detection γ-ray emission reaches this threshold values, by surplus valve 3 Exhaust Gas, avoid pressure excessive, damage device.
With reference to Fig. 2, when detection, rubber 10 is placed between plastics inner sleeve 4 and hard shell 1, plastics inner sleeve 4 is placed in rubber 10, by pouring the gas of certain pressure in the inside airtight annulus gum cover 5 of the 1st retaining valve 6, guarantee that plastics inner sleeve 4, rubber 10 and hard shell 1 fit together closely, are fixed on hard shell 1 plastics inner sleeve 4 and rubber 10, and have certain impermeability; Be filled with and detect gas (as hydrogen or ammonia etc.) by the 2nd retaining valve 7 again, in the time reaching setting value, pour air by the 3rd retaining valve 8, the mixed gas that detects gas and air enters in rubber 10 by the pore 9 at plastics inner sleeve 4 tops, if there is aperture gas leakage in rubber 10, can in hard shell 1, distribute the mixed gas that detects gas and air, in the time that special gas sensor 2 detects the mixed gas of leakage, the color of the luminotron on sensor 2 changes, prove that rubber 10 exists gas leakage, rubber 10 is defective; If the luminotron color on sensor 2 does not change, prove that rubber 10 is air tight, product is qualified.The effect of surplus valve 3 is that the unnecessary gas that enters hard shell 1 is discharged, and avoids producing excessive pressure, damages this device.
