kimray火焰監(jiān)測(cè)器ht-18pg資料下載action:direct action; pilot output pressure (yellow) increases withtemperature rise. as long as the temperature is above the set
point, the output will remain at supply pressure. if the pilot flamegoes out, the pressure decreases and drops to zero.
applications:
used as a pilot safety shutdown or as a high stack temperatureshutdown.
temperature range:
-30°f minimum to 2100°f maximum
-34°c minimum to 1149°c maximum
supply pressure:
5 psig minimum to 30 psig maximum.
operation:this thermostat consists of a stainless tube for monitoringthe pilot flame, which is connected by a low expansion alloyrod to a bellows assembly. the changes in the length ofthe stainless tube operate a pilot plug seat. the pilotplug consists of two stainless balls rigidly connected together.the seat at ball 1 is the output pressure vent (yellow toatmosphere). the seat at ball 2 is the supply pressure inlet(violet to yellow).
assume the set point on the ht 12pg is above the temperatureof the system. the vent at ball 1 is open and the inlet at
ball 2 is closed. output pressure (yellow) is at 0 psig or vented.
as the temperature rises in the system, the stainlesstube or outer tube increases in length to move the thermostatbellows assembly in a direction to first close the seat at ball 1(yellow to atmosphere) and open the seat at ball 2 (violet toyellow). output pressure (yellow) increases, opening a safetyvalve which was blocking gas supply for the burner and pilot lightsystem.
