kimray火焰监测器ht-18pg资料下载kimray火焰监测器ht-18pg系列的，【作用】正作用；指挥器输出压力(黄色)随温度上升而增加。只要温度超过设定的，输出将维持在供应压力。如果指挥器火焰熄灭，压力减小至零。【应用】作为一个安全关闭的指挥器或是作为一个高温堆栈关闭器【温度范围】-30°fmin至2100°fmax -34°cmin至1149°cmax【供气压力】5~30pisgmax 0.35~2.11kg/m2max【操作】这个温度调节器由一个控制指挥器火焰的不锈钢钢管组成，不锈钢管是由一个低膨胀合金杆连接到一个组合波纹管。在不锈钢钢管的长度上的变化控制着指挥器阀座。这指挥器阀座由连续两个不锈钢球硬性连接在一起。1球位置是输出压力出口(黄色到大气压)，2球位置是供气压力入口(紫色到黄色)假定在ht12pg上的设定温度在系统温度上。1球出口开而2球入口关闭。则输出压力(黄色)在0psig或负压。随着在该系统中温度的上升,不锈钢钢管或外管长度上增加去直接移动温度调节器的组合波纹管,从而*时间关闭在1球的位置(黄色到大气压)和开启在2球的位置(紫色到黄色),这将导致输出压力(黄色)增加,反之,则开启1球位置(黄色到大气压)和关闭2球位置(紫色到黄色),这将导致输出压力为0，这需要保持一个安全阀打开。 吴
kimray火焰监测器ht-18pg资料下载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.
