1. Equipment composition

The helium distribution box is mainly composed of test box and pressure control system; the whole test box body is made of stainless steel plate, the whole outer surface is wire drawing, and the overall appearance is elegant; the main components of the test box: Strengthening structure inside the workbench, with manual pressure regulating valve, globe valve, pressure gauge and pipeline.

2. Equipment characteristics

The helium distribution box is mainly used for pressure regulation output through a precision reduction valve, the system is equipped with globe valve and decompression valve, which can be used for pressure holding and pressure relief, each channel is installed safety valve, and overpressure can be automatically relieved, the pressure detection is mainly displayed by the self-contained pressure gauge; the system pipelines are connected by stainless steel pipes, and the whole system has simple structure and easy operation.
