Abstract
The invention discloses a soft package negative pressure sealing tester comprising a movable frame on which a vacuum chamber is fixed. A platen for positioning wrappage is arranged in the vacuum chamber; one end of a vapour-pressure type vacuum generator is communicated with the inner cavity of a vacuum chamber by a second manual valve with a locking press button, and the other end of the vapour-pressure type vacuum generator is communicated with a compressed air source by a first manual value with a locking press button; and the inner cavity of the vacuum chamber is also connected with a vacuum pressure gage. By adopting the above structure, the vacuum chamber and the control device of the soft package negative pressure sealing tester are integrally arranged on the frame, thus the tester is convenient to install, place or move and has convenient and visual operation.
Description
Technical field
The present invention relates to a kind of seal test device, particularly a kind of soft package negative pressure sealing tester.
Background technology
In the prior art, the general application of negative pressure principle of soft package negative pressure sealing tester, tested packing material is placed confined space, progressively increase the vacuum tightness of confined space, with reach set vacuum tightness whether bale broken gas leakage or bale broken gas leakage vacuum tightness value whether to surpass setting be discrimination standard, judge the sealing of packing material.For making the test effect apparent, generally tested packing material is immersed in the water, be convenient to observe the gas leakage situation of tested packing material.Yet common soft package negative pressure sealing tester vacuum chamber and control device are independent respectively not to become whole, installs, places or move difficulty, the placement of tested packing material or take out also inconveniently, control setting is complicated, operation with judge not directly perceived yet.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of easy to use, operate soft package negative pressure sealing tester intuitively.
In order to solve the problems of the technologies described above, a kind of soft package negative pressure sealing tester of the present invention, comprise movably vehicle frame, be fixed with vacuum chamber on the described vehicle frame, be provided with the pressing plate that is used for the packaging orientation thing in the vacuum chamber, have an end of vapour-pressure type vacuum generator manually to be with the locking press button valve to be communicated with the vacuum chamber inner chamber by second, the other end of vapour-pressure type vacuum generator is communicated with compressed air source by the first manual band locking press button valve, and described vacuum chamber inner chamber also is connected with pressure vacuum gauge.
As improvement of the technical scheme, described pressure vacuum gauge is that peak value keeps pressure vacuum gauge.
As further improvement in the technical proposal, described easy bottom is equipped with draining valve.
The invention has the beneficial effects as follows: this soft package negative pressure sealing tester is installed in vacuum chamber and control device one on the vehicle frame owing to adopted said structure, does not use power supply, is convenient to install, places or moves, more convenient operation, directly perceived.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Embodiment
With reference to Fig. 1, a kind of soft package negative pressure sealing tester of the present invention, comprise movably vehicle frame 1, be fixed with vacuum chamber 2 on the described vehicle frame 1, be provided with the pressing plate 3 that is used for the packaging orientation thing in the vacuum chamber 2, have an end of vapour-pressure type vacuum generator 4 manually to be with locking press button valve 5 to be communicated with vacuum chamber 2 inner chambers by second, the other end of vapour-pressure type vacuum generator 4 is communicated with compressed air source 7 by the first manual band locking press button valve 6, and described vacuum chamber 2 inner chambers also are connected with pressure vacuum gauge 8.This soft package negative pressure sealing tester is installed in vacuum chamber and control device one on the vehicle frame owing to adopted said structure, is convenient to install, places or moves, more convenient operation, directly perceived.
In the present embodiment, described pressure vacuum gauge 8 makes test result can keep being convenient to record for peak value keeps pressure vacuum gauge.The bottom of described vacuum chamber 2 is equipped with draining valve 9, is convenient to test the water in the vacuum chamber is discharged after finishing.Described vacuum chamber 2 tops are provided with vacuum room cover 10, and the bottom of this vacuum room cover 10 is provided with sealing joint strip 11.Described vacuum chamber 2 is made for organic glass, is convenient to test process and observes.Offer some through holes 31 on the described pressing plate 3, make the tested packing material of placement convenient and simple.
Before the test, connect compressed air source 7, add water to above plane on the pressing plate 3, press and connect second and manually be with locking press button valve 5, the passive pointer of pressure vacuum gauge 8 is transferred to smaller value toward vacuum chamber 2.Tested packing material is placed pressing plate 3 belows, builds vacuum room cover 10, pressed connect first manually band locking press button valve 6 open sources of the gas and begin test, observe tested packing material gas leakage situation and pressure vacuum gauge indicated value.If the pressurize pattern, then when pressure vacuum gauge alidade definite value, turn is closed the second manual band locking press button valve 5 and is turn-offed vacuum chambers, and turn is closed first and manually is with locking press button valve 6 again, the maintenance stipulated time, observes tested packing material gas leakage situation; If continue the pattern of vacuumizing, then when observing tested packing material and begin to leak gas bubbling, directly close the first manual band locking press button valve 6, the passive pointer indicated value of record pressure vacuum gauge 8.
