If because the valve gasket, valve damage, or because other comprised, pressure to rise and exports more than a certain value, the safety valve will be semi-automatic open the exhaust. When the pressure sensor testing to directed valve pressure, the lower pressure valve valve opening decreased; After testing to reduce the pressure valve pressure decreases, and reduce the pressure valve valve opening, to satisfied stem requirements. Apply after reducing pressure valve when make gas pressure drop to experiment the required range, again through other stem valves are fine tuning, make the gas input using the system. It is to try to take care of reduced pressure valve and make the safe use of devices, and reduce the pressure valve revealed the fault signal device. Direct utility reduce pressure valve of high pressure chamber and the cylinder petition, low pressure chamber for gas exports, and to use the system. 2, oxygen gas reduced pressure valve office principle: ( The appearance of the oxygen gas reduced pressure valve and office principle) 。 The most commonly used to reduce the pressure valve as oxygen gas to reduce the pressure valve, for short of oxygen gas meter. Using the first open the cylinder when the master switch, and then clockwise (low pressure gauge pressure adjustment screw, the compress the main spring and transmission film, spring cushion block and top Marine valve stem and valve open. 1, in the physical chemistry experiments, often need to use oxygen gas, nitrogen, hydrogen and argon gas, etc. High pressure table of value for the pressure of the gas storage in the cylinder. Q: the knowledge of oxygen gas reduced pressure valve recommend: a: the office of oxygen gas reduced pressure valve by the pressure imposed after the valve stem. The low pressure table outlet pressure can be adjusted by the screw stem. Reduce the pressure valve is equipped with safety relief valve. Suitable for use in water, steam, air medium pipeline. These common are stored in a dedicated high-pressure gas all cylinders. 。 Out so imported high-pressure body by high pressure chamber after throttling pressure lowered into the low pressure chamber, and the export to the office. This kind of valve in the pipeline should be water there is no danger. Turn the adjusting screw, change the height of the valve to open, so to adjust out high body over limit and achieve the required pressure value. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
