Abstract
The utility model relates to an air permeability test instrument which comprises a pipe line. One end of the pipe line is connected with a product to be tested, and the other end is communicated with a compressed air generator. The compressed air generator comprises a motor and a cylinder driven by the motor. The product to be tested is arranged in an airtight cavity, an airometer for detecting air permeability conditions is arranged on the airtight cavity, and a barometer for displaying air pressure is arranged in the pipe line. The air permeability test instrument is skillfully designed and manufactured with low cost, is extremely convenient to operate, and has excellent test effect.
Description
Technical field
The utility model relates to the ventilative testing apparatus of a kind of test products.
Background technology
Ventilative for some product needed, therefore need test product.It is existing that the strong ventilative test of gas trace has the liquid of packing in the U of the employing type pipe at mesohigh, U type pipe two ends connect the detection method of product and mesohigh source of the gas respectively, this method need manually calculate ventilative total amount, and be unfavorable for long-time test, it is at some product exclusive testing mould customized that some testing apparatuss are arranged, also having some is relatively large equipment and import equipment, and cost is higher, and enterprise is difficult to bear.
The utility model content
The technical problems to be solved in the utility model provides a kind of modern design, ventilative tester that cost of manufacture is low.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize:
A kind of ventilative tester, comprise the pipeline that an end is communicated with product to be tested, the other end is communicated with a pressure gas generation device, described pressure gas generation device comprises one by motor and the cylinder by motor driven, wherein, in a product installation to be tested and the seal chamber, the air meter that detects ventilative situation is installed on the sealing cavity, the rain glass that shows gaseous tension is installed in pipeline.
Air pressure for the ease of the control test is provided with switch in pipeline.
For the ease of control cylinder, described motor is provided with the speed regulator of governor motor speed.
The utility model design is ingenious, and cost of manufacture is low, operates also very conveniently, and has good test effect.
[description of drawings]
Fig. 1 is the utility model example structure synoptic diagram.
[embodiment]
Defective at prior art exists describes in further detail of the present utility model for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing:
As shown in Figure 1, the scheme that discloses of present embodiment mainly is the improvement project at existing problem propositions such as testing cost height, testing complex when seal test.
Should comprise the pipeline 1 that an end is communicated with product to be tested, the other end is communicated with a pressure gas generation device 2 by ventilative tester, described pressure gas generation device comprises a cylinder 22 that passes through motor 21 and pass through motor driven, in a product installation to be tested and the seal chamber 5, the air meter 4 that detects ventilative situation is installed on the sealing cavity, the rain glass 3 and the switch 6 that show gaseous tension are installed in pipeline.For the ease of control motor 21, be provided with the speed regulator 7 of governor motor speed at motor 21.
During test, at first be installed on product 8 to be tested in the seal chamber 5 and block up in pipeline 1 end, make switch 6 be in closed condition, open motor 21, the piston that motor promotes cylinder 22 moves, gas in the compression cylinder 22, when rain glass 3 shows that air pressure in the pipelines 1 reaches the required air pressure of this product to be detected and requires, open switch 6, air-flow flows to product to be tested, after the time that requires when detecting, observe the reading of the demonstration of air meter 4, thereby judge whether sealing part product exists ventilative and how many Air permenbilities is by this product to be detected.
As seen, the utility model has promptly been realized the sealing of this series products is detected by easy structure, has promptly reduced the cost of such checkout equipment, and the operation of also being more convenient for is practical.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
