Background technology
Existing electric pressure cooking saucepan product all will carry out working pressure and detect before dispatching from the factory.The common way of enterprise is through in pot, adding water, become the accordance that water vapour comes testing pressure and pot body sealing through to boil water, thereby the working pressure and the cooking temp that guarantee product being controlled in the setting range.But this detection method length consuming time, enterprise need take bigger production site when producing in batches, consumes bigger electric energy, causes production efficiency low, and simultaneously, the steam of generation when test makes workman's working environment overheated etc.
The applicant has applied for a kind of anhydrous detection method; The pressure cooker of promptly through pressurized air assembling being accomplished leaks hunting and jumps the detection of disconnected value with pressure; In order to detect above-mentioned performance exactly; Therefore introduced the operation of before detection, pressure cooker being tamped in the method; It mainly acts on through pressure and eliminates product internal part, the particularly assembly problems such as burr between pressure displacement transmission metal parts, and the entire product reliable in structure is fixed, and the limitation of product structure secure fixation is lacked, can't be made to compensation product pressurising time in anhydrous detection (cold conditions) method partially.In the process of compacting, also to detect pot body simultaneously and whether leak gas, therefore need special compacting and leak-checking apparatus and compacting leak detection method.
Summary of the invention
Pressurized air compacting and leak-checking apparatus and compacting leak detection method that the technical matters that the present invention solves provides a kind of detection to be used for electric pressure cooking saucepan accurately.
The present invention is for addressing the above problem, and the technical scheme that is adopted is following:
A kind of pressurized air compacting and leak-checking apparatus that is used for electric pressure cooking saucepan; It is characterized in that: comprise electric pressure cooking saucepan; Pressure transducer and draft tube with the electric pressure cooking saucepan internal communication; Said pressure transducer is connected with the pressure display control device; The output terminal of pressure display control device is connected with first timing circuit, and the output terminal of first timing circuit is connected with second timing circuit and CS device respectively, and said CS device is arranged on the tracheae that connects source of the gas and electric pressure cooking saucepan air intake opening; Said first timing circuit is by the start-up control circuit triggers.
Be connected with the inflation test adaptor on the vent valve of said electric pressure cooking saucepan, said air intake opening and pressure transducer are connected on the inflation test adaptor.
Also be provided with pressure size CS between said CS device and the source of the gas.
The present invention crosses disclosed method: a kind of compacting leak detection method that is applied on said compacting of claim 1 and the leak-checking apparatus: it is characterized in that comprising the steps:
The first step; Connect the start-up control circuit; First timing circuit picks up counting according to the signal of start-up control circuit, and the CS device is opened in electric pressure cooking saucepan and inflated simultaneously, and the real-time pressure in the pressure display control device display voltage power pot also continues the surge pressure in the record pressure cooker;
In second step, when real-time pressure reaches the setting value of pressure display control device, and when satisfying first setting-up time between the timing of first timing circuit institute, the CS device breaks off, and stops in electric pressure cooking saucepan, to inflate; Simultaneously, the startup of second timing circuit picks up counting;
In the 3rd step, when satisfying second setting-up time between the timing of second timing circuit institute, the compacting operation is accomplished; The pressure display control device shows and the interior real-time pressure of record pressure cooker simultaneously;
In the 4th step, the pressure display control device is compared the real-time pressure that write down in the 3rd step with the surge pressure that the pressure display control device is write down, if difference less than setting range, then electric pressure cooking saucepan is air tight; If the about setting range of difference, then electric pressure cooking saucepan gas leakage.
Wherein: first setting-up time in the step 2 is 2s～6s.
The range of set value of pressure display control device is 70kPa～110kPa in the step 2.
Second setting-up time in the step 3 is 2s～10s.
Difference setting range in the step 4 is 0kPa～10kPa.
Among the present invention, pressure transducer is equipped with at inflation test adaptor top, and the inflation tracheae is equipped with in the side.Pressure transducer links to each other with pressure display control device (like digital manometer), and its function is to convert pressure signal to electric signal, the force value size is reacted on the display screen again; Tracheae receives the setting value size and CS device (like the solenoid valve) control of start-up control circuit (like start button), first timing circuit (like the time relay) and pressure display control device; When inner gas pressure reaches setting value; When inflationtime satisfies the first timing circuit setting-up time, start the pressurize compacting time simultaneously, in the pressurize compacting time of setting; If air leakage in the scope of setting, qualified products then.
Compare with existing technology; The present invention has following technique effect: the present invention's employing charges into compressed-air actuated mode and electric pressure cooking saucepan is tamped simultaneously and the detection of leaking gas in product; Thereby, thereby significantly reduced the input of relevant device for the anhydrous detection method of realization provides possibility.Technology of the present invention has also overcome electric pressure cooking saucepan industry high temperature and high pressure steam that generally adopt, that bring with the sealing of high pressure, high temperature vapor test products and has been prone to the problem that calcination operating personnel skin and bad border of operation become extremely hot because of heating, thereby has improved the comfortableness of operational security and operating environment greatly.The present invention simultaneously can adopt digital pressure gauge and pressure transducer, converts pressure signal into electric signal, shows through display screen, and the pressure that can show accurately in real time in the product container changes, and can read clearly.
