Each enclosed cylinder seals corresponding accommodating cavity under shed via a cylinder seal circle；Described 1st a plurality of accommodating cavitys or so
Penetrate through successively, which forms left through hole and right through hole with vacuum valve body intersection；
1st a plurality of sealing test gas-tpe fittings, each sealing test gas-tpe fitting one end insertion is corresponding to be housed on cavity
Opening, the other end stretch out；
1st a plurality of action gaskets, each action gasket are arranged on corresponding described sealing test gas-tpe fitting one end
Bottom.
One plug and a vacuum source gas-tpe fitting, wherein, plug is arranged on left through hole, both right through holes first, vacuum source gas
It is another that pipe fitting is arranged on left through hole, both right through holes.
Preferably, the described 1st a plurality of accommodating cavitys are symmetricly set in vacuum valve body.
Preferably, the left through hole is located at the middle part at two horizontal end of vacuum valve body with right through hole respectively, what left and right through hole was formed
Through channel is located at the 1st a plurality of accommodating cavity tops.
Using the technical solution of the above, the utility model substitutes vacuum electromagnetic of high cost using the higher cylinder of sexual valence
Valve, reduces equipment cost；The utility model uses a cylinder solenoid valve indirect control multichannel vacuum break-make, simplifies control
Circuit, reduces power consumption.
Brief description of the drawings
Fig. 1 is the exploded view of the utility model；
Fig. 2 is the sectional view of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
With reference to Fig. 1 and Fig. 2, the utility model provides a kind of tightness testing clamp, including：
One enclosed cylinder group, is connected in series by the 1st a plurality of enclosed cylinders 2；
One vacuum valve body 1, is equipped with the 1st a plurality of accommodating cavitys being intervally arranged in it, each accommodating cavity upper and lower opening,
Each enclosed cylinder seals corresponding accommodating cavity under shed via a cylinder seal circle 3；Described 1st a plurality of accommodating cavitys or so
Penetrate through successively, which forms left through hole and right through hole with vacuum valve body intersection；
1st a plurality of sealing test gas-tpe fittings 6, each corresponding accommodating cavity of 6 one end of sealing test gas-tpe fitting insertion
Upper shed, the other end stretch out；
1st a plurality of action gaskets 4, each action gasket 4 are arranged on corresponding described 6 one end of sealing test gas-tpe fitting
Bottom.
One plug 7 and a vacuum source gas-tpe fitting 5, wherein, plug 7 is arranged on left through hole, both right through holes first, vacuum source
It is another that gas-tpe fitting 5 is arranged on left through hole, both right through holes.
Wherein, the described 1st a plurality of accommodating cavitys are symmetricly set in vacuum valve body 1.
