Cause damage to the gas valve
10/16/2013 4:33:34 PM
Affect the normal use of gas valve are many factors that can mainly be categorized into the following three kinds .
gas impact of temperament
a. If the gas contains a certain quantity of S02, H2S, aromatic hydrocarbons, tar and other substances, easily lead to damage of the rubber member .
b. If the gas contains a certain quantity of S02, H2S, H2O, O2 and other substances , will lead to copper , iron and other metal parts of the corrosion damage .
e. If the gas contains a certain amount of particles of dust , after prolonged use , it will affect the clearance sliding fit metal parts , resulting in equipment failure and malfunction .
d. If the gas contains a certain amount of particles of dust , and the flow in the large, high dust may cause damage to the casing and other components . The impact due to wear or damage caused by more common in the door station .
e. If the gas contains a certain amount of readily at room temperature, the phase change material, such as elemental sulfur, naphthalene , anthracene, light oil and other substances will produce fluid and the valve stem , cavity , diaphragm and other surface grain attachment , affect the normal use of the regulator .
actual use conditions of
a. If the inlet and outlet pressure is too large and the larger flow , will metal parts, especially the housing cavitation damage.
b. ambient temperature is too high , too low , in some cases dramatically reduced while the heating medium temperature caused by poor too low, will be on the film , and other rubber parts damage.
c. If improper equipment selection , equipment, the actual range of the rated through capacity through capacity difference is too large, moving parts of equipment likely to cause total or partial damage.
of the device itself
a. device defect structure itself .
b. equipment parts used material defects.
In the above affect the normal use of gas regulator factors , some can cause local damage can be repaired , while some will form an overall permanent damage to the device .
