Medical Center oxygen supply system from the central station of oxygen, pressure relief devices, piping, valves and other components of oxygen quickly socket terminals. Central station is at the heart of medical oxygen gas stations Medical Center oxygen gas supply system, the oxygen inside the station via pipelines and transported to the rapid decompression device socket terminal each ward each ward, and then through the humidifier after oxygen for the patient, It is safe, fast, convenient medical gases, is a modern medical equipment in recent years, rapid development. Pressure gauge pressure gauge structural principle by the measurement system, indicating system, magnetic electrical contact device, housing, adjustment device and junction boxes (plug seat) and other components. General pressure gauge is used for measurement of copper and copper alloys corrode gas, negative pressure of the liquid medium, stainless steel pressure gauge for measuring corrode stainless steel gas liquid medium plus or minus pressure medical gas equipment and signals when the pressure reaches a predetermined value, connected to the control circuit, to achieve automatic control of the alarm was the purpose. Electrical contacts operating principle is based on the Bourdon tube measuring system under pressure measured media, forcing the end of the spring tube to produce the corresponding elastic deformation of a displacement of the medical gas installation works, by means of the lever and the transmission gear mechanism to amplify, by instruction (with contact) by fixed gear on the measured value indicated on the dial. At the same time, when it and the contacts (upper or lower) to set the pointer on the contact (moving off or moving together) instantaneous, resulting control system circuitry to disconnect or connect, to achieve automatic control and hair The purpose of the alarm signal.
