medical high pressure oxygen gas regulator oxygen regulator low prices

This series of pressure reducer using metal diaphragm and the mother of hard seal type, suitable for pure gas, the general standard gas, process gas and corrosive gas pressure reducer requirements.

I thoroughly remove the oil, water and dust at the location of the cylinder and piping system and the reducer, and once the impurities enter the gas pressure reducer, it will cause the polluting of the gas, obstruction of the gas passage or other troubles,

II If the thread on the pipe deformation, can not be installed with the gas pressure reducer, do not force connection, otherwise it will lead to management system and the gas pressure reducer on the damage, causing serious accidents.

Third, the operation

  1. Before the gas enters the pressure reducer, make sure that the piping system (including the pressure reducer) is purged or evacuated as required.

  2. Before the gas enters the pressure reducer, make sure that the pressure relief handle is in a fully unscrewed state (counterclockwise). Otherwise, the initial pressure at the initial stage of the air supply may damage the diaphragm, resulting in a pressure reducer Failure, serious will hurt the person.

  3, slowly open the valve on the inlet side of the valve, with soap or special detector on the pressure reducer at the connection leak detection.

  Note: When opening the air supply valve, the body may not be right or back to the pressure reducer.

 4, turn the pressure regulator clockwise pressure regulator, the pressure (or flow) transferred to what you need, and with soap or special detector on the pressure relief device at the connection leak detection.

   Note: If there is any abnormal mechanical vibration, noise, jamming or abnormal pressure increase during the supply of the reducer, it indicates that the pressure reducer has been faulty and should be stopped immediately.

Fourth, daily inspection

  1, gas pressure reducer no gas, confirm the pressure gauge pointer back to zero.

  2, in the gas pressure reducer containing gas, with soapy water (or household neutral detergent plus 10 to 20 times the water diluted solution) or a special detector to check the thread and the connection parts are leaked.

  3, after the gas, to confirm the gas pressure can be continuously adjusted.

  4, after the gas, to confirm that no gas leak from the safety valve.

Five, repair

If there is a series of circumstances, you need to replace the parts, at this time must not be disassembly, please contact the company or dealer.

1. When the gas pressure reducer contains gas, the gas leaks from the threaded connections.

2. When the gas pressure reducer does not contain gas, the pressure gauge pointer does not return to zero.

3. After the gas supply, the pressure can not be adjusted continuously.

4. After the gas supply, the pressure gauge pointer does not bounce

5. After the gas supply, the pressure is abnormally high.

6. Pressure gauge is damaged

Six important safety warning

This safety warning is valid for any media gas pressure reducer

I operator must be a qualified operator who has been trained.

II Before use, make sure that the pressure regulator is in a fully loose state (counterclockwise). Otherwise, the initial pressure of the air supply may damage the diaphragm, resulting in a major safety accident.

 III The need for periodic inspection of piping systems (including pressure reducers), especially when the piping system is subject to collision or vibration, should be leaked. To ensure the use of security.

 IV use of vibration, noise or other abnormalities found in the process, should immediately stop using.

 V The Company can advise on the material of the reducer according to the general material application form. But for the special media media, the company does not guarantee material compatibility, by the customer according to the sample of the material rotation and is responsible for their own.

Note:

I  The gas pressure reducer is shipped with the instruction manual / warranty card and certificate, please read the safekeeping.

II  The specifications of the gas pressure reducer are specified in the product warranty card product parameters.
