Description
Technical Field
The utility model relates to an air tightness detection device, especially an air tightness detection bucket that cooperation circulating water vacuum pump used.
Background
For the packaging of pharmaceutical tablets, ensuring that the drug is not affected with moisture and deterioration in the effective period is the most basic requirement and the most important principle. The medicine packing materials are required to have enough tightness, the quality and the efficacy of the medicine can be ensured only by blocking all destructive factors such as external oxygen, light, heat and the like, people can take the medicine with confidence, a special air tightness detector is generally purchased for detection at present, the cost is high, the structure is complex, the maintenance is inconvenient, and an inventor develops an air tightness detection barrel matched with the use by utilizing the common circulating water vacuum in a laboratory according to the actual conditions of enterprise production.
Disclosure of Invention
In order to solve the problems, the invention provides an air tightness detection barrel matched with a circulating water vacuum pump, which adopts the following technical scheme:
the utility model provides an air tightness detection barrel that cooperation circulating water vacuum pump used, the staving is opened by last staving and lower staving and is connected the constitution, is provided with the aspirating hole on the staving, and the staving top is provided with the water inlet, and the staving bottom is provided with the outlet.
The top of the barrel body is provided with a pressure gauge.
The joint of the upper barrel body and the lower barrel body is provided with a sealing ring.

Compared with the prior art, the utility model discloses beneficial effect: the air tightness detection device has the advantages of low cost, simple structure, convenience in operation and maintenance, is matched with a circulating water vacuum pump for use, and fully utilizes the existing resources to complete air tightness detection.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the structure of the vacuum pump used with circulating water of the present invention;
in the figure, 1, a pressure gauge, 2, an air exhaust hole, 3, a lower barrel body, 4, supporting legs, 5, a water outlet, 6, a water inlet, 7, an upper barrel body, 8, an air exhaust pipe, 9, a circulating water vacuum pump, 10 and a buckle.
Detailed Description
Example 1
As shown in fig. 1-2, during the air tightness detection, the aluminum-plastic plate is placed in the barrel body, the upper barrel body 7 and the lower barrel body 3 are closed and fastened by the buckle 10, the cover of the water inlet 6 is opened, water with colors is injected into the barrel body, the cover is closed, two exhaust pipes 8 of the circulating water vacuum pump 9 are hermetically connected with the exhaust holes 2 on the barrel body, the circulating water vacuum pump 9 is opened, air in the barrel body is exhausted, the interior of the barrel body is changed into a negative pressure state, the aluminum-plastic plate is bulged at the moment, and whether water enters the barrel body or not is observed to confirm the air tightness.
Example 2
As shown in fig. 1, when the airtightness test is completed, the cover of the drain port 5 of the lower tub 3 is opened to allow water in the tub to flow out, and then the tub is cleaned.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
