Fig. 2 is the schematic diagram of container tightness detecting and controlling system.
Corresponding entitled of each reference in figure: 1-source of the gas, 2-filter, 3-fine motion pressure regulator valve, 4-electromagnetic valve, 5-is inverse
Stream valve, 6-air gauge.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
Implement such as shown in Fig. 1 ~ Fig. 2 for one of inventive container device for detecting sealability, including input gas circuit and control
System.
Input gas circuit includes filter 2, fine motion pressure regulator valve 3, electromagnetic valve 4 and reflux valve 5, when the import of filter 2 uses
It is connected with source of the gas 1, it is ensured that on the casing needing detection, carry out the gas output of controllable pressure.Electromagnetic valve 4 is three port two position electricity
Magnet valve, uses as control valve, electric time conducting input gas circuit, in dead electricity time cut-off input gas circuit.The output of input gas circuit
End is provided with the interface for being connected with testing container, and connection has for detecting gas in container pressure before reflux valve 5
Air gauge 6, reflux valve 5 enters testing container for only making gas so that in pressure maintaining period casing and air gauge 6 be one whole
Body, it is to avoid distorted signals.
As in figure 2 it is shown, control system includes start button SB1, stop button SB2, auxiliary reclay KM1, middle relay
Device KM2, inflationtime relay K T1, dwell time relay K T2, auxiliary reclay KM3 and qualified display lamp, gas leakage instruction
Lamp, above-mentioned each components and parts are combined into ventilating control part, holding pressure control part and result output part.Wherein respectively control part
The circle of circuit bottom represents binding post, is connecting object below circle.
Start button SB1 switchs as start button, obtains for control electromagnetic valve 4 and inflationtime relay K T1 simultaneously
Electricity；Stop button SB2 has three normally-closed contacts, connects with electromagnetic valve 4, air gauge 6, dwell time relay K T2 respectively；In
Between relay K M1 for realize the self-locking of start button SB1 and inflationtime relay electric, be used for realizing inflationtime
The electric contact that obtains of relay K T1 is normally opened contact；Auxiliary reclay KM2 is for realizing the self-locking of stop button SB2, continues in centre
Electrical equipment KM3 is for realizing the self-locking of the normally opened contact of inflationtime relay K T1.Switch uses auxiliary reclay to realize self-locking
The conventional techniques means of this area, concrete principle and structure the most no longer describe in detail.
Qualified display lamp and gas leakage display lamp are connected with the signal output part of air gauge 6, if pressurize detects after terminating
Air pressure be not less than setting value, air gauge 6 will to qualified display lamp output signal, point out testing result be qualified, if pressurize
The air pressure detected after end is less than setting value, then air gauge 6 will be to gas leakage display lamp output signal, and prompting testing result is leakage
Gas.
After start button SB1 is pressed, auxiliary reclay KM1, KM2 are energized and complete self-locking, power directly to air gauge 6,
And powered to electromagnetic valve 4 by the normally-closed contact of inflationtime relay K T1, inflation starts.The coil of auxiliary reclay KM1 is certainly
After lock, to the coil power supply of inflationtime relay K T1, after power-on time reaches setting value, coil electricity, now ventilating control
The normally-closed contact of inflationtime relay K T1 in part disconnects, and electromagnetic valve 4 dead electricity, inflation terminates；Meanwhile, holding pressure control portion
The normally-closed contact Guan Bi of inflationtime relay K T1 in Fen, auxiliary reclay KM3 is energized self-locking, dwell time relay K T2
Coil starts timing.After dwell time relay K T2 coil arrives setting value, its normally opened contact closes, now, and air gauge 6
The signal of telecommunication is conveyed to the qualified finger of correspondence by output signal (qualified or gas leakage) by the normally opened contact of dwell time relay K T2
Show lamp or gas leakage display lamp, complete air-leakage test.After detection end-of-job, pressing stop button SB2, corresponding element device breaks
Electricity, treats that next time presses start button SB1.Owing to this detection device have employed automatically controlled, remotely operation the most also can be conveniently realized.
Control system in i.e. above-described embodiment of embodiment of container tightness detecting and controlling system in the present invention, this
Place repeats no more.
In the above-described embodiments, electromagnetic valve 4 and inflationtime relay K T1 are switched by start button and control simultaneously, at this
In other embodiments of invention, it is also possible to open while realizing both by the break-make of the whole circuit of control system.It addition,
In above-described embodiment, result suggestion device is qualified display lamp and gas leakage display lamp, in other embodiments, result suggestion device
Can also replace with other forms, such as pressurize termination instruction lamp, testing staff learns that the dwell time arrives after receiving prompting, then
By observing pressure gauge reading or the reading by air gauge at the end of the pressurize of recording device records 6, result can be made
Final judgement.Furthermore, in other embodiments, air gauge 6 can also be constantly in "on" position.
