Operation

(1) Open the oxygen cylinder regulator or gassing operation must be slow. If the valve opening speed is too fast, the working portion of the regulator due to the adiabatic compression of the gas temperature is greatly improved, so that the parts may be made of an organic material such as rubber filler, a fibrous pad rubber membrane fire burn and can reducer completely burned out. In addition, due to the excessive discharge static sparks produced gas and pressure reducer with oil, etc., can cause a fire burning burn Regulator parts. 

(2) Notice prior to installation and open the cylinder valve regulator when: Before installing the regulator, oxygen cylinder valve slightly open, blowing dirt, to prevent dust and moisture into the pressure reducer. When opening the cylinder valve, valve outlets shall be aligned with the operator or others, to prevent high-pressure gas suddenly out of wounding. The outlet gas pressure reducer rubber pipe joints must be annealed wire or clamps tightened; prevent disengagement occurs after aspiration hazard. 

Note (3) regulator handling and at work: When handling the pressure reducer threaded fittings must be taken to prevent slip teeth, so not strong spin injection. In the course of the work must observe the pressure gauge value. Loosen the regulator should stop working before the regulator screw, and then close the oxygen cylinder valve and the gas pressure reducer inside slowly exhausted, so that you can protect the springs and pressure valves from damage. After work, we should remove the regulator on the cylinder, to be properly preserved.

Precautions 

(1) The Regulator must periodically school repair, pressure gauge must be regularly tested. This is done to ensure the accuracy and reliability of the regulator gauge readings. In use, there is an air leak is found reducer, pressure gauge action not working, etc., should be timely maintenance [1]. 

(2) freezing process regulator. Reducer found in the course of the freeze, thaw with hot water or steam, never use a flame or red iron baking. After heating regulator must blow off any remaining moisture. [1] 

(3) pressure reducer must be kept clean. May not contaminated grease, dirt on the pressure reducer, if oil must be used in order to wipe clean after.

Valve connection size:

The method is to make the throttle valve outlet pressure below the inlet pressure, outlet pressure and to maintain a nearly constant pressure control valve. An automatic line is reduced specialized working pressure means that it can be a high pressure liquid line before the valve to the valve to reduce the piping required level. 

Here the main transmission medium is water. Valves are widely used in high-rise buildings, urban water supply network of high pressure area, mines and other occasions to ensure that the water supply system in each point of access to appropriate service pressure and flow. Given the extent of the dropout rate and the waste water is almost the same pressure proportional to the size of the water supply system, thus reducing valve with improved system operating conditions and potential water-saving effect, according to statistics about 30% of its water-saving effect. 

  Many types of valve structure, a common past, a film type, the spring piston and so on. The basic role is to rely on the principle of pressure reducing valve flow channel to reduce local resistance to the flow of water pressure, water pressure drop range automatically adjusted by connecting valve film or import and export of water pressure on both sides of the piston. 

Also some new valves since 2007, such as fixed ratio pressure reducing valve. Fixed ratio decompression valve principle is to use floating piston pressure ratio control, import and export terminal side of the piston and the pressure ratio is inversely proportional to area ratio. This valve work smoothly without vibration; valve body without spring, so no spring corrosion, metal fatigue failure of consideration; good sealing performance does not leak, thus both reducing the dynamic pressure (water flow) and less static pressure (flow 0:00); especially the pressure is reduced without affecting the water flow. DN15 ~ DN100 valve usually has other specifications, before the valve, the pressure of work were<1MPa and 0.1 ~ 0.5MPa, pressure range error of ± 5% ~ 10%.
