Seal closure be provided with pressure detecting table, described stop valve is arranged between two pressure detecting tables；By pressure detecting table
The internal pressure of seal closure and the output pressure of compression pump are detected respectively, and whether both real-time judge pressure is unified, sentenced with this
Whether disconnected internal pressure is stable, and whether pressure reaction still leaks.
Used as a kind of improvement of the present utility model, the diameter of described elastic packing mouth is less than the opening diameter of seal closure,
Described gas-flow closure layer is fitted tightly over the inner side of elastic packing mouth.Seal closure is inhaled by the utility model by elastic packing mouth
It is attached on reactor housing, less elastic packing mouth diameter is conducive to improving the sealing of device, while passing through gas-flow closure
Layer carries out auxiliary seal, improves sealing effectiveness further.
As a kind of improvement of the present utility model, the described elastic sealing layer overall knot integrated with elastic packing mouth
Structure, the tight of elastic sealing layer are connected on the opening of seal closure；The overall structure of integration, good seal performance, it is difficult
Gas leakage, device detection is precisely.
The utility model has the advantage of：The utility model by the overall structure of sealing, by connecting rod by device
Seal closure adsorbs on the housing of any reactor housing；According to the arbitrary shape of reactor housing, the elasticity on seal closure is close
Sealing and support spring can with the shape of reactor shell random variation, seal adsorbed close is in the outer of reactor housing
Side, extracts the air in seal closure out by vacuum-pumping pipeline, when there is leakage in reactor housing, the vacuum inside seal closure
Can change, judge that reactor housing is leaked on the position in time.
