Description of vacuum valve system for checking package tightness

application

Sealing control of the package is required during the production process to prevent damage to the goods. The package that may be leaked must be discovered in time and measures taken. This system is mainly used for checking the sealing of packaging in batch production or packaging.

design

First, the package is placed in a sealed chamber. Then, evacuate the inside of the chamber and then inject it into the helium. If the package has leaked, the helium will enter the package and the pressure inside the chamber will drop. Finally, the helium is extracted, the chamber is opened, and the package is taken out.

Features:

■ The valve body is made of metal aluminum
■ Sealing material is EPDM
■ Medium: neutral gas
■ Medium temperature: -10 ° C to 50 ° C
■ Load cycle: continuous operation
■ Connection port: the air source end is a threaded interface, and the vacuum end is a three-clamp interface.
■ Clean type: The valve and valve block combination for analysis is thoroughly cleaned and the organic content is ppb.
■ Vacuum valve can reach 1 x 10-8 mbar.l/s
■ The vacuum valve block can also reach 1 x 10-8 mbar. l/s
■ The expansion of the valve block has been considered. Depending on the level of automation, valves are sometimes added
