Gas distributor
Technical Field
The invention belongs to the technical field of instrument equipment, and particularly relates to a gas distributor.
background
The gas distributor is a common device in the instrument industry, and the internal pressure values of the device and the system are led to a pressure gauge or a pressure sensor through a positive/negative pressure leading pipe to be measured, then the internal pressure values are converted into flow, and finally signals are transmitted to a control system. The gas distributor used in the existing market has the problems of complex pipeline and more joints, so that the number of leakage points in practice is increased correspondingly. Measurement errors are easily generated, and the maintenance workload of the pipeline is correspondingly increased. Therefore, how to develop a new gas distributor that can reduce the gas leakage points of the equipment, thereby reducing the pipeline maintenance workload, and simultaneously ensuring the detection accuracy of the pressure sensor is a direction that needs to be studied by those skilled in the art.
