Description
Technical field
The utility model relates to the device that a kind of electric pressure cooking saucepan is tamped and leaked hunting after assembling is accomplished.
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.
Summary of the invention
Pressurized air compacting and leak-checking apparatus that the technical matters that the utility model solves provides a kind of detection to be used for electric pressure cooking saucepan accurately.
The utility model 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.
Be provided with first setting-up time in said first timing circuit, this first setting-up time is 2s～6s.
Be provided with setting value in the said pressure display control device, this range of set value is 70kPa～110kPa.
Be provided with second setting-up time in said second timing circuit, this second setting-up time is 2s～10s.
In the utility model, 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 utlity model has following technique effect: the utility model 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.The utility model technology 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 utility model can adopt digital pressure gauge and pressure transducer simultaneously, 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.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the entire work process synoptic diagram of the utility model.
Embodiment
Below in conjunction with figure and practical implementation case, set forth the concrete structure of the utility model in detail.
,, adapter 9 is inflated in pressure measurement inserted on the vent valve of tested electric pressure cooking saucepan 10, and keep closely cooperating each other, and other parts are connected by shown in Figure 1 after tested electric pressure cooking saucepan 10 assemblings are accomplished with shown in the accompanying drawing 2 with reference to figure 1.After connecting completion; Start-up control circuit 1; Like the power initiation button etc., at this moment first timing circuit 2 starts with pressure display control device 4, and CS device 6 (like solenoid valves) are opened simultaneously; By source of the gas compressed and supplied air after the big mini controller 5 of the pressure in CS device 6 the place aheads is regulated; Charge in the tested electric pressure cooking saucepan 10 through tracheae 11 and pressure measurement inflation adapter 9, the pressure signal in the tested electric pressure cooking saucepan 10 is through pressure transducer 8 detections and deliver to pressure display control device 4, and (this setting value is 110KPa to the real-time pressure value that tests out when pressure display control device 4 in this method less than its setting value; Setting value is selected in 70 ~ 110KPa scope as the case may be); And first timing circuit 2 (first setting-up time can not be 2～6s, is generally 3～5s), continues to tested electric pressure cooking saucepan 10 in, to inflate when not reaching first setting-up time time.Wherein pressure display control device 4 will continue to write down the pressure peak in the tested electric pressure cooking saucepan.Real-time pressure value in tested electric pressure cooking saucepan reaches the setting value of pressure display control device 4; And the time that the first timing circuit meter gets is when satisfying first setting-up time; CS device 6 breaks off, and stops in tested electric pressure cooking saucepan, to inflate, and starts second timing circuit 3 simultaneously and picks up counting; When timing circuit 3 time when satisfying second setting-up time; Second setting-up time can be 2～10s; Be generally 3～8s), the peak value that write down pressure value that is shown on the pressure display control device 4 and front compares, if its difference relatively is within 0～10KPa scope; Then tested electric pressure cooking saucepan 10 is air tight, otherwise tested electric pressure cooking saucepan 10 is underproof.The whole like this process of leaking hunting and tamping is accomplished.
