Abstract
The utility model relates to a test device for the air tightness of a steel drum which comprises a control cabinet, an air pump and a steel drum sealing joint. The air pump is arranged inside the control cabinet and is communicated with the steel drum sealing joint arranged on an upper cover of the steel drum in inserting mode. The output end of the air pump is communicated with a quick connector which is clamped tightly on an annular convex edge formed by the periphery of the upper end of the steel drum sealing joint and is communicated with the steel drum sealing joint. The test device for the air tightness of the steel drum has simple structure and low cost. During installation, the quick connector moves vertically and enables the steel drum sealing joint not to rotate, thereby avoiding the leakage and improving the accuracy of the measurement.
Description
Technical field
The utility model relates to the voltage-withstand test technical field, especially a kind of steel drum air tightness test device.
Background technology
The liquid type article, such as inflammability liquid such as common gasoline, diesel oil, all need transport by the steel drum of sealing, and the pressure in the steel drum can cause breaking of steel drum after surpassing certain limit, the liquid type article that leak will cause serious harm, so the pressure-resistant stopping property of steel drum is particularly important.
The normal at present withstand voltage air tightness test instrument structure of using is: comprise control box and steel drum sealing adaptor, the leading flank setting-in key-press module and the display module of control box, key-press module is connected the central control module in the control box with display module, central control module drives air pump and solenoid valve is realized supplying gas and exhaust, the output terminal of air pump connects a gas circuit sealing adaptor by tracheae, and the output terminal of this gas circuit sealing adaptor is mounted on the steel drum sealing adaptor that covers on the steel drum.The structure of steel drum sealing adaptor is: comprise a hollow tube, make the spanner screens that is used for the spanner chucking in the lower end of hollow tube, the hollow tube outer rim that is positioned at spanner screens top installs the snap ring that is used to block steel drum loam cake bottom surface, the movable clip of engagement suit on the made external thread of hollow tube outer rim above the snap ring, this clip is used to block steel drum loam cake upper surface.
Before test, at first on steel drum, cover boring, use special-shaped spanner that the steel drum sealing adaptor is installed in the made through hole of steel drum loam cake, again movable clip is tightened on the hollow tube that hollow tube stretches out steel drum loam cake outside, between this moment snap ring and the steel drum loam cake and between movable clip and the steel drum loam cake sealing gasket is installed all.After the steel drum sealing adaptor installed, engagement was tightened the gas circuit sealing adaptor to be communicated with the air pump in the control box on the external thread of hollow tube upper end at last.
In the said structure, the gas circuit sealing adaptor of An Zhuaning need mesh the upper end that is sleeved on hollow tube at last, and such rotary manipulation may make hollow tube rotate simultaneously, causes not tight that hollow tube combines with the steel drum loam cake thus, cause gas leakage, cause the error of steel drum voltage-withstand test.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low and the steel drum air tightness test device that can accurately measure.
A kind of steel drum air tightness test device, comprise control box, air pump and steel drum sealing adaptor, air pump is installed in the control box and is communicated with the steel drum sealing adaptor that is inlaid in the steel drum loam cake, it is characterized in that: the output terminal of described air pump is communicated with a quick connector, and this quick connector tightens the made annular ridge of steel drum sealing adaptor upper end outer rim and is communicated with the sealing of steel drum sealing adaptor.
And, the coaxial annular groove of making on the outer rim of made annular ridge below, described steel drum sealing adaptor upper end.
Advantage of the present utility model and beneficial effect are:
The utility model is simple in structure, cost is low, steel drum sealing adaptor upper end outer rim is made an annular ridge, this fin blocks the elasticity fixture block of quick connector inwall and the two sealing is communicated with, in order to improve the steadiness of connection, the coaxial annular groove of making on the outer rim below the made annular ridge in steel drum sealing adaptor upper end, this annular groove makes more solid that the elasticity fixture block of quick connector inwall clamps, in installation process, quick connector is to move up and down, the steel drum sealing adaptor is rotated, can not cause leakage, improve the accuracy of measuring.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged drawing of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of steel drum air tightness test device, shown in Fig. 1～2, comprise control box 1, air pump 4 and steel drum sealing adaptor 8, air pump is installed in the control box and is communicated with the steel drum sealing adaptor that is inlaid in steel drum 6 loam cakes, innovation of the present utility model is: the output terminal of air pump is communicated with a quick connector 7 by tracheae 5, and this quick connector tightens the made annular ridge 11 of steel drum sealing adaptor upper end outer rim and is communicated with the sealing of steel drum sealing adaptor.
Owing to need very firm being connected between quick connector and the steel drum sealing adaptor, the coaxial annular groove 12 of making on the outer rim on the steel drum sealing adaptor below the made annular ridge.
The course of work of the present utility model is:
1. at first on steel drum, cover boring, use special-shaped spanner to block the spanner screens 17 of hollow tube upper end, the steel drum sealing adaptor is installed in the made through hole of steel drum loam cake, again movable clip 10 is tightened on the hollow tube 13 that stretches out steel drum loam cake outside, lower seal pad 15 and last sealing gasket 14 are installed respectively between snap ring 16 and the steel drum loam cake and between movable clip and the steel drum loam cake.
2. the tester is installed on the upper end of hollow tube with quick connector, owing to be vertical plug-in mounting, can not screw the removable cover 9 that covers on the steel drum simultaneously because of rotation causes leakage.
3. the tester starts tester to finish the withstand voltage air tightness test of steel drum according to the display module 2 and the key-press module 3 set pressure numerical value of control box leading flank.
The utility model is simple in structure, cost is low, and in installation process, quick connector is to move up and down, and the steel drum sealing adaptor is rotated, and can not cause leakage, improved the accuracy of measuring, and operating process is convenient, has saved the running time.
