What type of control system is it that consists of one temperature controller, another temperature controller, and then two valves?
It should be two-way control, which allows for an expanded range of flow regulation; if opening the valve on one pipeline is not sufficient, then the valve on another pipeline can be activated.
It is quite common on steam drums: the vent lines on steam drums usually consist of two lines and two control valves. The difference is that pressure is used to control these two valves.
TIC2135 should be for range division; then what is the name of this overall control mechanism between TIC2134 and TIC2135?
There is a difference between the common three-charging adjustment sensation on the drum and this one as well
This control system is called: the TIC-2136 temperature and TIC-2135 temperature cascade proportional control system. That is, the main temperature of TIC-2136 and the secondary temperature of TIC-2135 are connected in a cascade configuration, with the secondary loop operating in a split-range mode; it is thus a system that combines cascade and split-range operations.
For example: 2135A/B is a mixing valve for cold/hot water, used to control the temperature of the mixed water. The mixed water is used to heat (or remove heat) from the process material, and the temperature of the material becomes 2136.
