[0002] A gas valve distribution box is a highly efficient and safe device for distributing high-purity gas from a single source to multiple applications. This device can regulate the gas pressure at the points of use in the distribution branches. VMB gas valve distribution boxes are widely used in semiconductor, photovoltaic, electronics, and medical manufacturing industries. In the transportation of electronic specialty gases, the introduction of VMB is a core unit for one-to-many, point-to-point branching, ensuring not only multi-point gas use but also gas safety. A Chinese utility model patent (publication number: CN218671615U) discloses a semi-automatic gas valve distribution box. Through the cooperation of a valve mounting plate and a support column, it allows for vertical adjustment during valve installation. The sliding round tubes at both ends of the fixed metal plate are fitted onto the support column, and then the position of the sliding round tubes is adjusted vertically as needed. The fastening bolts at the upper end of the sliding round tubes are then locked, firmly fixing the sliding round tubes to the support column. The gas valve is then installed on the fixed metal plate, and the positioning holes at the upper end of the fixed metal plate facilitate bolt fixing.
