Abstract
The utility model discloses a device for detecting the air tightness, which is characterized by an air charging device, a manometer and an air tightness detecting tube, wherein one end of the air tightness detecting tube is connected with an air outlet of the air charging device, and the other end thereof is connected with a device to be detected; and the manometer is connected with the air charging device. The device has the advantages of convenient and reliable detection, simple structure and low cost, and can be extensively applied to detect the air tightness of various devices.
Description
Technical field
The utility model relates to the bubble-tight device of a kind of detection.
Background technology
Existing detect bubble-tight device, mostly complex structure, and cost height, and also operating of having is also cumbersome, is unfavorable for broader applications.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of airtight pick-up unit, and it is easy to detect reliable, and simple in structure, and cost is low.
The technical scheme that its technical matters that solves the utility model adopts is: this airtight pick-up unit, comprise aerating device, tensimeter, airtight detector tube, and the gas outlet of described airtight detector tube one end and aerating device is tightly connected, and the other end is connected with device to be measured; Described tensimeter is connected on the aerating device.
As further technical scheme of the present utility model:
In this airtight pick-up unit, between the gas outlet of described airtight detector tube one end and aerating device for being threaded.
In this airtight pick-up unit, between described airtight detector tube and the device to be measured for being threaded.
In this airtight pick-up unit, the outside surface of described airtight detector tube is provided with coaxial prism-shaped boss.
In this airtight pick-up unit, described prism-shaped boss is positive six prismatic boss.
The beneficial effects of the utility model are: it is easy to detect reliable, and simple in structure, and cost is low, and can be widely used in the impermeability detection of various devices.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment,
Fig. 2 is the cut-open view of airtight detector tube among the utility model embodiment,
Fig. 3 is the left view of Fig. 2,
Among the figure: 1 aerating device, 2 tensimeters, 3 airtight detector tubes, 4 positive six prismatic boss.
Embodiment
As shown in Figure 1, this airtight pick-up unit comprises aerating device 1, tensimeter 2, airtight detector tube 3, and described tensimeter 2 is connected on the aerating device 1.One end of described airtight detector tube 3 and the gas outlet of aerating device 1 are tightly connected, and between the two for being threaded, fitting operation is convenient and swift and impermeability good.The other end of airtight detector tube 3 and device to be measured are also by being threaded.Shown in Fig. 2,3, the outside surface of airtight detector tube 3 is provided with coaxial positive hexa-prism boss 4.During fitting operation, can use spanner to turn airtight detector tube 3, guarantee that the connection of thread at airtight detector tube two ends is tightr reliable.
After connecting with device to be measured, starting aerating device 1 be device inflation to be measured by airtight detector tube 3, after grasping inflation and reach certain pressure by tensimeter 2, stops to inflate.After leaving standstill a period of time, check tensimeter 2 again, if manometric index does not have to change then shows that the impermeability of tested device is fine.If the index of tensimeter 2 shows that pressure diminishes, show that then the tested device impermeability is bad, there is gas leakage to exist.
Claims (5)
