Abstract
The utility model relates to a device for testing internal pressure of a glass bottle. The device comprises a hollow pipe with two ends closed, an inner cavity of the hollow pipe is sequentially communicated with an evacuation pipe, an air inlet pipe and an output pipe from top to bottom, a first valve, a second valve and a third valve are arranged on the evacuation pipe, the air inlet pipe and the output pipe, respectively, and the output pipe is connected with the opening of the glass bottle in a fit way. The device for testing the internal pressure of the glass bottle is simple in structure and low in cost and can efficiently and accurately test that whether the internal pressure born by the glass bottle is qualified or not while safe operation of testers is guaranteed.
Description
Technical field
The utility model relates to compression testing device in a kind of vial.
Background technology
Vial is because the advantage that corrosion-resistant, resistance to oxidation and material are easy to get, usually for holding gas or liquid reagent.If but the pressure of gas or liquid is excessive, usually can damage vial, cause vial to burst, so that cause security incident.Therefore,, for the consideration to safety in production, enterprise often needs the vial to producing to compress into row test in bearing, and rejects substandard product.Compression testing device complex structure in existing vial, expensive, enterprise is difficult to bear, and therefore how to provide a kind of simple in structure, with low cost and measure compression testing device in efficient vial, is those skilled in the art's difficult problems urgently to be resolved hurrily.
Utility model content
the purpose of this utility model is to provide compression testing device in a kind of vial, and the utility model is simple in structure, with low cost, efficiently and accurately tested glass bottle whether bear interior pressure qualified.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Compression testing device in vial, described device comprises the hollow tube of two ends closure, the inner chamber of hollow tube is from top to bottom communicated with evacuated tube, draft tube and efferent duct successively, on evacuated tube, draft tube and efferent duct, be respectively equipped with the first valve, second valve and the 3rd valve, the bottleneck of efferent duct and vial is connected.
Preferably, the inner chamber of hollow tube is also communicated with water inlet pipe, and water inlet pipe is provided with the 4th valve.
Preferably, described device comprises protection container, and the efferent duct after connection and vial are positioned at protection container.
Preferably, described protection container is bucket.
Preferably, described hollow tube bottom is connected with bearing.
Preferably, described device also comprises tensimeter, and tensimeter is arranged on hollow tube top and is communicated with the inner chamber of hollow tube.
When work, the bottleneck of vial and efferent duct are connected, and by both junction sealings, then vial and part efferent duct are put into bucket, in bucket, fill water.Close second valve, open the first valve, the 3rd valve and the 4th valve, by water inlet pipe to water filling in hollow tube, current are in efferent duct input vial, in the time that water is discharged from evacuated tube, represent that water has filled vial emptying gas in vial, the air pressure that makes vial is conventional atmospheric pressure, close the first valve, the 4th valve this moment, open second valve and the 3rd valve, in hollow tube, pass into gas by draft tube, gas acts on vial inwall by efferent duct, and tensimeter shows the interior pressure that vial bears immediately simultaneously.In the time that tensimeter shows that air pressure numerical value is required to bear pressure by specification product, close second valve and stop passing into gas.Hold and press after certain hour, the vial in observation bucket, if bottle is intact, is specification product; If bottle bursts, be substandard product, but due to the protective effect of bucket, bottle bursts the safety that can not endanger tester.
Compared with prior art, tool has the following advantages the utility model: the utility model is simple in structure, with low cost, ensureing on tester's the basis of safety work, efficiently and accurately tested glass bottle whether bear interior pressure qualified.
Brief description of the drawings
Fig. 1 is the structural representation of the interior compression testing device of vial in embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, compression testing device in vial, described device comprises the hollow tube 1 of two ends closure, hollow tube 1 top is provided with tensimeter 10, bottom is connected with bearing 11, the inner chamber of hollow tube 1 from top to bottom successively with tensimeter 10, evacuated tube 2, draft tube 3, water inlet pipe 4 and efferent duct 5 are communicated with, evacuated tube 2, draft tube 3, on water inlet pipe 4 and efferent duct 5, be respectively equipped with the first valve 6, second valve 7, the 4th valve 8 and the 3rd valve 9, efferent duct 5 is connected with the bottleneck of vial 13, efferent duct 5 after connection is positioned at bucket 12 with vial 13, the in-built full water of bucket 12.
When work, the bottleneck of vial 13 and efferent duct 5 are connected, and by both junction sealings, then vial 13 and part efferent duct 5 are put into bucket 12, in bucket 12, fill water.Close second valve 7, open the first valve 6, the 3rd valve 9 and the 4th valve 8, by water inlet pipe 4 to the interior water filling of hollow tube 1, current are inputted in vial 13 from efferent duct 5, in the time that water is discharged from evacuated tube 2, represent that water has filled vial 13 emptying gas in vial 13, the air pressure that makes vial 13 is conventional atmospheric pressure, close the first valve 6, the 4th valve 8 this moment, open second valve 7, in hollow tube 1, pass into gas by draft tube 3, gas acts on vial 13 inwalls by efferent duct 5, and tensimeter 10 shows the interior pressure that vial 13 bears immediately simultaneously.In the time that tensimeter 10 shows that air pressure numerical value is required to bear pressure by specification product, close second valve 7 and stop passing into gas.Hold and press after certain hour, the vial 13 in observation bucket 12, if bottle is intact, is specification product; If bottle bursts, be substandard product, but due to the protective effect of bucket 12, even if bottle bursts the safety that can not endanger tester.
