Four Vacuum Chambers Helium Leak Testing Equipment for Small Four - way Valve
This system is suitable for air-tightness detection of four-way valve to ensure the airtightness of the product.
According to the basic principle of helium leak detection, with helium as the tracer gas, helium is filled into the workpiece in the vacuum chamber, and then the helium leak detector can accurately and quickly judge the leakage of the workpiece.
Equipment Characteristics:
1 . The system has 4 vacuum chambers.
2 . With helium recovery device, which can save cost of the use of helium
3 . Automatically control the test process
4 . High precision , easy operation and fast test cycle
Technical Parameters: (will be customized according to client's requirements)
| Workpiece | Small four-way valve |
| Vacuum chamber | 4, (2 chambers on each side of Assembly Line) |
| Detectability | 2 workpieces in each chamber |
| Fixture | 2pcs |
| Helium Pressure for Indicating Leakage | 4.15Mpa(Downward adjustable) |
| Gas pressure for gross leak | 4.150MPa (Downward adjustable) |

Operaiting process
The system has 4 vacuum chambers. The operator puts the workpiece into the fixture in the vacuum chamber, then turn on the button, the door of vacuum chamber is close and workpieces will be clapped automatically. The system can automatically complete the whole process like large leakage and strength detection, air exhaust, helium filling, Helium recovery and so on.
