Abstract
The utility model relates to an air tightness checking device for a sensor checking machine. The air tightness checking device is used with the cooperation of a pressure detector and is used for detecting the air tightness of the installation of a sealing ring. The air tightness checking device comprises an air tightness checking ring, the air tightness checking ring is a hollow cylindrical structure, the upper end of the air tightness checking ring is provided with a connecting hole connected with the pressure detector, a lower opening of the air tightness checking ring is an inclined opening with a narrow inside and a wide outside, and the vertical cross section of the opening is in a isosceles trapezoid shape. The beneficial effects of the air tightness checking device for the sensor checking machine are that the structure is simple, the air tightness checking ring and the sealing ring are just fit with each other, and the measurement of the air tightness of the sealing ring is facilitated.
Description
Technical field
The utility model relates to the airtight testing fixture of a kind of sensor inspection machine.
Background technology
In sensor inspection machine, relate to the parts that multiple needs sealing arranges, its junction is usually provided with O-ring seal, and the sealing property that therefore detects O-ring seal is most important.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of sensor inspection machine airtight testing fixture.
The utility model solves the technical scheme that its technical matters adopts: the airtight testing fixture of a kind of sensor inspection machine, support the use with pressure detecting instrument, the sealing of installing for detection of O-ring seal, comprise airtight inspection ring, the cylinder-like structure that airtight inspection ring is hollow, its upper end is provided with the connecting hole being connected with pressure detecting instrument, and its lower ending opening is the interior narrow outer wide beveled that longitudinal cross-section is isosceles trapezoid.
The beneficial effects of the utility model are: simple in structure, airtight inspection ring and O-ring seal just in time agree with, and are convenient for measuring the air-tightness of O-ring seal.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. O-ring seal, 2. connecting hole.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The airtight testing fixture of a kind of sensor inspection machine as shown in Figure 1, support the use with pressure detecting instrument, the sealing of installing for detection of O-ring seal 1, comprise airtight inspection ring, the cylinder-like structure that airtight inspection ring is hollow, its upper end is provided with the connecting hole 2 being connected with pressure detecting instrument, and its lower ending opening is the interior narrow outer wide beveled that longitudinal cross-section is isosceles trapezoid.
When actual use, connecting hole 2 is connected with pressure detecting instrument, pressure detecting instrument applies 0.6MPa pressure in the chamber of airtight inspection ring, is continuously applied 12 seconds, if pressure drop value is no more than 0.02MPa, represent that O-ring seal 1 sealing is good, otherwise sealing is poor.
The small-bore place of airtight inspection ring lower ending opening just in time agrees with O-ring seal 1, and O-ring seal 1 is out of shape less, can not damage O-ring seal 1, and after detecting, facilitates O-ring seal 1 to depart from from the heavy caliber of airtight inspection ring lower ending opening, easy to use.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to claim scope.
Claims (1)
