It uses:
1, clean associated pipeline must be purged using preceding.
2, all to pass through acceptance(check), the pry regulator to put into operation should all reach requirement, and periodically be tieed up
Shield maintenance operation.
3, never Quick open valve door, equipment in violent valve opening gate pole pry regulator easy to damage；
4, it never is filled with excess pressure to outlet conduit, otherwise can damages pry regulator inner body.
5, setting pressure should follow principle from high to low, by one Xiang Jinhang of step 1 item, can not grasp
It is too urgent.
6, after pressure setting, it need to be detected and close pressure, verify its performance, if reach required value.
7, pressure setting can open outlet valve after meeting the requirements, and must not open outlet before this
Valve, to prevent unexpected generation.
8, in debugging process, No Open Flames, prevents electrostatic from generating, forbid collision, tap pipeline and
Equipment.
9, precision instrument should be noted that protection, big to prevent pressure oscillation, damage instrument.
10, when heat exchanger heats, this group of heater power source can only be used, the power supply of two groups of heaters cannot be opened simultaneously,
With the power supply of burnout-proof heater.
11, the reset operation of stop valve:
(1) stop valve must carry out manual reset operation after performing cutoff action in the duct.
(2) cutting reason should be found out before carrying out reset operation, is the failure of compression shock or pressure regulator in pipe network, arranged
Rear can be reset operation out.
(3) when carrying out stop valve reset operation, it is necessary to close the disengaging valve and outlet pressures table of regulator
Under needle valve.
(4) imported valve is slowly opened, outlet pressure is observed, pressure normally opens outlet valve afterwards.

2, the heat transferring medium in heat exchanger must be anti-icing fluid, and the model of anti-icing fluid is depending on the local lowest temperature.When
Minimum more than anti-icing fluid to use temperature, anti-icing fluid need to be put only, replace anti-icing fluid by (freezing point is at -40 DEG C).
3, when maintenance activity, power supply should be closed, need to first confirm that surrounding is detained without gas leakage or combustion gas.
4, when piping need to remove, internal gas should be emptied in advance.
5, when carrying out electrical repair and replacement electric fittings, it is necessary to be initially switched off power supply.
6, gas displacement should be re-started after repairing, and carries out the every of pry regulator restarting and prepares, details are such as
Under:
(1) airtight experiment: check that each interface, flange etc. have No leakage with suds.
(2) start pry regulator by gas supply program.
7, clean inside pressure regulator, when in gas medium containing relatively heavy dirt, should periodically to pressure regulator internal maintenance,
Cleaning periodically should be checked or be replaced to the rubber parts of easy swelling or aging, such as gasket seal, with guarantee safe way and
Normal use.
