Container intracavity conducting, the internal diameter of the gas-guide tube are slightly larger than the plug outer diameter of sensor, and gas-guide tube for plug inside it
Free to slide, which is mounted on gas-guide tube upper end；Adapter is also installed, soft air pipe is by adapter and very on vacuum tank
The conducting of empty container inner cavity.
Further, the soft air pipe connects a vacuum pump.
Further, the vacuum tank is made of shell, cover board, sealing ring, fastening bolt；One side opening of shell,
Cover board lid in a manner of openable and closable closes on shell nozzle, and sealing ring is arranged between cover board and shell；The housing side is opened
There is mounting hole, the adapter is mounted in the mounting hole.
Further, the case top opens up gas port, and the gas-guide tube lower end assigns into the gas port.
Further, the cover board or shell are equipped with observation window.
After adopting the above scheme, the utility model is as follows for the seal process of absolute pressure transducer：
1）Plug is placed on the seal of sensor；
2）Vacuum tank is opened, sensor is fixedly mounted in vacuum tank, sensor seal is being directed at gas-guide tube just
Lower section；
3）Close vacuum tank and air valve, it is ensured that sealing；
4）Vacuum tank is inverted, plug is allowed to be fallen into gas-guide tube by gravity, close to air valve；
5）Vacuum pump is opened, ceaselessly gives evacuating atmosphere in vacuum vessel by soft air pipe, sensor internal is also at vacuum shape
State；
6）When vacuum degree reaches requirement, vacuum tank is turned over；
7）Plug（Steel ball）Under the effect of gravity, it falls on the seal of sensor, seals seal；
8）Stop that evacuating atmosphere in vacuum vessel is opened air valve, air is allowed to enter gas-guide tube, external pressure, which is greater than, at this time passes
Sensor air pressure inside, pressure difference cause plug to get lodged on seal not fall off；
9）Container is opened, sensor is taken out, is welded together using pressure drag electrode holder plug with sensor.
The beneficial effects of the utility model are：The vacuum sealing jig structure is simple, at low cost, easy to use, safety,
Realize the quick carry out vacuumize process to absolute pressure transducer, and when plug seals stomata, once in leakage sensor
There is no pressure difference outside, can find gas leakage at once, if sealing failure, can also repeat to seal.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
