What is the function of a gas pressure regulator in a piping system?
a.To measure total gas consumption
b.To trap sediment before the appliance
c.To bond the piping electrically
d.To reduce and hold gas pressure to a stable, lower value for downstream piping or an appliance
Giải thích
A regulator takes a higher, sometimes variable, supply pressure and delivers a lower, steady outlet pressure that the piping and appliance are designed for. Service and line regulators are used where supply pressure exceeds what the appliances need, such as stepping a 2 psi system down at each appliance. Regulators are not meters, sediment traps, or bonding devices.
