Description
Technical field
The utility model relates to a kind of metallic bellows helium Mass Spectrometer Method device, leak detection assistance platform device.
Background technology
Past, subject matter was in carrying out the leak detection process of metallic bellows, and the single-piece operating efficiency is low, adopted the rubber cushion cap seal, and sealing is poor.Carry out vacuumizing---leak detection---venting repeatedly, the utilization rate of equipment is too low, and has seriously reduced the serviceable life of this high-precision equipment of helium spectrum leak locator.
Summary of the invention
The purpose of this invention is to provide a kind of metallic bellows helium mass spectrum leak detection assistance platform, but multistation carries out forvacuum and helium mass spectrum leak detection simultaneously.
Metallic bellows helium mass spectrum leak detection assistance platform, comprise that helium mass spectrometer leak detector, vacuum take out system and multistation operator's console and vacuum piping in advance, it is characterized in that having on the worktable a plurality of boss arranged side by side, cavity and center pit are arranged in the boss, fixedly the strut and tie of corrugated tube is positioned at the center pit of worktable, the strut and tie center pit has radially pore, and the bottom is pore and vacuum line and leak locator pipeline connection that tensimeter and solenoid valve are all arranged radially, and the strut and tie lower end is connected with cylinder piston by pin.
The leak rate that the design is fit to middle-size and small-size precise corrugated pipe detects, comprise two circuits systems: the roughing pipe of helium mass spectrometer leak detector high vacuum pipeline and plug-in vacuum pump, can realize that by controlling tensimeter in each worktable pipeline and electromagnetic valve forvacuum carries out simultaneously with detecting.Each worktable is independently, adopts multistation line production along separate routes, realizes that multiloop uses simultaneously, also can partly use, and all the other are idle, save the time of personnel's measuring instrument, are applicable to the detection of part in batches.Realize automatic, the sealing reliably of corrugated tube by the position-limiting action of worktable inner cavity and strut and tie extruding rubber ring, also can not be shifted, improved stability in vacuum.Change the size of working plate port and strut and tie, can realize that the corrugated tube leak rate of variety classes port form detects.With plug-in vacuum pump measured piece is carried out forvacuum,, then can close plug-in vacuum pump loop, use flexibly if the measured piece cavity volume is little, but the multistation operation have and do not destroy tested corrugated tube, sealing is convenient.

Embodiment
Metallic bellows helium mass spectrum leak detection assistance platform device, stationary table is on support, as the location, seal the operating platform of tested corrugated tube, see Fig. 1, it is characterized in that a plurality of boss arranged side by side and control desk 3 are arranged on the worktable 1, see Fig. 2, cavity and center pit are arranged in the boss, with the strut and tie 7 that is with corrugated tube 9 and O-ring seal 10 center pit of packing into, strut and tie 7 center pits have radially pore 6, strut and tie connects three-way pipe 7 times, connects plug-in vacuum pump forvacuum system 4 and leak locator high pressure vacuum system 5 respectively, and strut and tie 7 lower ends are connected by the piston of pin with cylinder 11.In plug-in vacuum pump forvacuum system 4 and leak locator high pressure vacuum system 5 pipelines tensimeter and solenoid valve 2 are arranged respectively, solenoid valve 2 is connected with control panel button circuit respectively, control the circulation of vacuum pump or leak locator pipeline respectively or close, can monitor the strut and tie in each boss respectively, implement independent operation.
The operation instruction of this device:
1, testing fixture state guarantees that solenoid valve 1～solenoid valve 10 is in off state, opens helium spectrum leak locator and vacuumizes preheating, also opens plug-in vacuum pump simultaneously, and the piping inner chamber is carried out forvacuum.
2, cylinder is placed push mode, by the guide effect of strut and tie 7 upper ends and the position-limiting action of worktable 1 boss cavity inwall, tested metallic bellows 9 is enclosed within on the strut and tie 7, the straight wall of corrugated tube 9 leans against on the worktable 1 cavity inwall, be positioned on the worktable, operating switch places drop-down position with cylinder 11, and piston will promote strut and tie 7 and move down, 10 distortion of crush seal cushion rubber also are adjacent to corrugated tube 9 straight wall inside surfaces, realize positiver sealing.
3, the vacuum glue that takes a morsel is coated with 8 times round walls of sealing rubber plug and touches evenly, is pressed in tested corrugated tube 9 upper ends, with just hand steered, opens solenoid valve 2 simultaneously, and corrugated tube is vacuumized.In this process, guiding by strut and tie 7 upper ends and position-limiting action can prevent that the crooked and overcompression of corrugated tube from producing distortion.Then, carry out the operation of other stations successively.
4, close the solenoid valve of forvacuum pipeline earlier, open the solenoid valve of helium spectrum leak locator high pressure vacuum pipeline again, press " leak detection " button of helium spectrum leak locator, the first station corrugated tube is hunted leak.After finishing, press the tested corrugated tube that helium is composed " venting " button of leak locator and taken off first station, and close solenoid valve.
So the corrugated tube detection of other station is finished in operation successively.
Claims (2)
