Abstract
The utility model discloses a packing box seal tightness test device, including membrane resultant pressure meter, constant voltage equipment, the rubber tube of ventilating, second valve and first valve, the packing box connects gradually membrane resultant pressure meter, second valve, constant voltage equipment and first valve through the rubber tube of ventilating, do you form constant voltage equipment membrane resultant pressure meter the rubber tube of ventilating packing box series circuit. The utility model discloses high, the easy operation of precision is counted to the mesolamella resultant pressure, the reading is directly perceived, through adopting constant voltage equipment, once only adjust pressure in the experiment, avoid packing box of every survey all to need pressure regulating power, improved work efficiency, the important is the harm that can avoid hypertoxic article healthy to operating personnel, has solved simultaneously because the defect of mercury gauge leads to the problem that mercury spills over when causing the maloperation.
Description
Technical field
This utility model belongs to field of sealing technology, and in particular to a kind of packing cratess leak tightness test device.
Background technology
For a long time, the sealing propertytest assay device of factory's packaging product metal box uses U-shaped bath of glass
Silver meter.The pressure (unit for kPa) of regulation is converted into into mercury column before test high and set in U-shaped hydrargyrum meter, according to mercury column
The stable time judges metal box whether gas leakage, judges whether the sealing of metal box is qualified with this.This detection test side
Method is to set up the sixties in last century, and precision is relatively low, reading is difficult, and each metal box is intended to weight in seal tightness test
New pressurization Adjustment Tests pressure.U-shaped glass mercury meter is easily damaged during long-term use, needs Jing often to change hydrargyrum meter.
Meanwhile, if misoperation in process of the test, easily make outside the hydrargyrum discharger in hydrargyrum meter, cause Poisons (hydrargyrum) to spill
Packaging scene, it is impossible to recycled, the healthy and environment of site operation personnel is had a negative impact.
Utility model content
The purpose of this utility model is to provide a kind of packing cratess leak tightness test device, solves using hypertoxic detection means
Inconvenience that (hydrargyrum) brings and the security hidden trouble for existing, also solve that existing detection means precision is relatively low, reading is difficult asks
Topic, improves work efficiency.
The technical solution of the utility model is：A kind of packing cratess leak tightness test device, it is characterised in that：Including film combined pressure
Power meter 1, constant voltage equipment 2, ventilation rubber tube 3, the second valve 5 and the first valve 6；Packing cratess are connected successively by ventilation rubber tube 3
Connect film resultant pressure meter 1, the second valve 5, the valve 6 of constant voltage equipment 2 and first；Form constant voltage equipment-film resultant pressure meter-ventilation rubber
Pipe-packing cratess series circuit.
Beneficial effect：Film resultant pressure meter high precision, easy to operate, reading are directly perceived in this utility model；By being filled using constant pressure
Put, disposable adjustment pressure in test, it is to avoid often survey a packing cratess and be required for pressure regulation power, improve work efficiency；Important
It is the harm that Poisons (hydrargyrum) can be avoided healthy to operator, while solving because the defect of mercury gauge is made
The problem for causing hydrargyrum to overflow when maloperation.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
To make the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
Describe in further detail.
This utility model provides a kind of packing cratess leak tightness test device, including film resultant pressure meter 1, constant voltage equipment 2, ventilation
Rubber tube 3, the second valve 5 and the first valve 6；
Packing cratess 4 are sequentially connected film resultant pressure meter 1, the second valve 5, the valve of constant voltage equipment 2 and first by ventilation rubber tube 3
Door 6；Packaging case lid is fabricated to dedicated test lid, has covered passage, and the passage is connected with ventilation rubber tube 3, forms constant pressure
Device-film resultant pressure meter-pneumatics trachea-packing cratess series circuit；
During detection, the first valve of compressed air 6 is first turned on, adjust the setting value of constant voltage equipment, allow air pressure slowly to rise, directly
Authorized pressure is reached to pipeline, the second valve 5 is closed, starts timing, at the appointed time, by the stable shape of film resultant pressure meter
Condition judges the whether qualified sealing to detect packing cratess of sealing of packing cratess judging packing cratess whether gas leakage with this.Such as
Fruit gas leakage, film resultant pressure meter reading is reduced, if air tight, film resultant pressure meter reading will stabilise at setting value.
The packing cratess can be the materials such as metal box, plastic box.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
