Preferably, fluid sealant is adopted to carry out reinforcing sealing between described seal glass and described open port.
Preferably, described air-tightness detection device also includes a set pipe fitting, and described set pipe fitting is provided with multiple air inlet and a gas outlet, it is adaptable to have the accurate device of multiple gas outlet.
Air-tightness detection device described in the utility model, the open port of accurate device is undertaken sealing formation by seal glass and seals space by it, and adopt peristaltic pump to carry out evacuation work, by negative pressure measurement table, the air-tightness sealing space after evacuation is monitored, thus obtaining the airtight coefficient of accurate device, air-tightness detection device described in the utility model, simple in construction, easy to operate, the air-tightness result obtained by its detection is also more accurate, meets the accurate device requirement to precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of air-tightness detection device described in the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 1, embodiment of the present utility model provides a kind of air-tightness detection device, for detecting the air-tightness of the accurate device 2 with open port, described air-tightness detection device includes the seal glass 1 for open port is sealed, and the airway 3 being connected with the gas outlet of accurate device 2, the pipe bed of other end traverse one peristaltic pump 4 of described airway 3 the formation evacuation gas outlet 31 that extends out, the airway 3 between described peristaltic pump 4 and described accurate device 2 is provided with negative pressure measurement table 5.
Air-tightness detection device described in the utility model, it is for detecting the less accurate device of interior sealed space 2, owing to the sealing space of device is less, if adopting general evacuator, power is bigger, its testing result is comparatively rough, it is unable to reach the requirement of accurate device 2 precision, therefore, this utility model adopts peristaltic pump 4 that the sealing space of accurate device 2 is carried out vacuum pumping, peristaltic pump 4 is by rotating rotor, airway 3 is circulated and rolls, airway 3 inside is made to gradually form vacuum, the relative evacuator of speed of its evacuation is more applicable for accurate device 2, and the effect of evacuation to compare evacuator more excellent.Preferably, described peristaltic pump 4 starts building to make by the Power supply belt of a 24V.
For improving the result of air-leakage test further, fluid sealant between described seal glass 1 and described open port, is adopted to carry out reinforcing sealing.
Described air-tightness detection device is adopted to carry out air-leakage test step as follows:
nullFirst with seal glass 1, the open port of accurate device 2 is sealed，And coating fluid sealant seals further between seal glass 1 and described open port，A sealing space is formed between described seal glass 1 and described accurate device 2，Afterwards the gas outlet of airway 3 with accurate device 2 is connected，The other end of described airway 3 is through the pipe bed the rotor and pump case of peristaltic pump 4，And the formation evacuation gas outlet 31 that extends out，Airway 3 between described accurate device 2 and peristaltic pump 4 arranges negative pressure measurement table 5，When all parts assemble complete，Start power supply，Rotor in peristaltic pump 4 starts to rotate，By airway 3, the sealing space in accurate device 2 is carried out evacuation，After in sealing space, full form becomes vacuum，Check the display numerical value of negative pressure measurement table 5，And monitor whether numerical value changes，Numerical value after stable is recorded，Recover to seal the normal barometric pressure in space，Repeatedly it is carried out repeatedly evacuation test，Record negative pressure value，Take repeatedly the meansigma methods of negative pressure value，The airtight coefficient of this accurate device 2 can be accessed，Complete air-leakage test.
Owing to some accurate device 2 has multiple gas outlet, therefore, described air-tightness detection device also includes a set pipe fitting 6, and described set pipe fitting 6 is provided with multiple air inlet and a gas outlet, for the gas outlet of multiple accurate devices 2 is grouped as one, it is simple to air-leakage test.
Air-tightness detection device described in the utility model, the open port of accurate device 2 is undertaken sealing formation by seal glass 1 and seals space by it, and adopt peristaltic pump 4 to carry out evacuation work, by negative pressure measurement table 5, the air-tightness sealing space after evacuation is monitored, thus obtaining the airtight coefficient of accurate device 2, air-tightness detection device described in the utility model, simple in construction, easy to operate, the air-tightness result obtained by its detection is also more accurate, meets the accurate device 2 requirement to precision.
The above detailed description of the invention of the present utility model, is not intended that the restriction to this utility model protection domain.Any various other made according to technology of the present utility model design change and deformation accordingly, should be included in this utility model scope of the claims.
