On the one hand, when water tank 112 internal pressures surpassed authorized pressure, control tool 120 will be controlled the operation of steam raising plant 110, more particularly is exactly that control heater 114 is out of service.When the steam raising plant 110 of i.e. this invention heats water generates steam, in case foreign matters such as calcium carbonate stop up the vapor injection port 116 of water tank 112, when water tank 112 pressure inside surpass authorized pressure, control tool 120 will cut off the operation of heater 114, prevents that pressure from continuing to rise and steam raising plant 110 is impaired.

To the specifically visible Fig. 2 of the control tool of this invention, control tool 120 is to send the switching device formation that " starting on " signal stops the heater operation when surpassing authorized pressure by water tank 112 internal pressures.

That is to say that above-mentioned control tool is made of switching device, when water tank 112 pressure inside surpassed authorized pressure, switching device can send " starting on " signal made heater out of service.This switching device 120 is positioned at water tank one side 112, preferably is positioned at water tank 112 tops.This is that steam can rise to top, is convenient to sensed pressure when causing pressure to rise because of seething with excitement along with the water in the water tank 112.

Fig. 3 is the sectional view that carries out along with the III-III line, is the concrete structure figure that shows in detail according to switching device 120 first embodiment.

With reference to Fig. 3, switching device 120 has been equipped with first elastic wall 122 that expands along with water tank 112 internal pressures, with the contact switch that is each positioned at first elastic wall and water tank 112 opposite faces, this contact switch can have optionally contact with it along with first elastic wall expansion 122.

This just requires water tank 112 at least a portion will have the multiple wall construction of inwall shown in Figure 3 132 and outer wall 130.The part of inwall 132 is preferably installed first elastic wall 122 that expands along with water tank 112 internal pressures in the multiple wall.Because when the water tank internal pressure rises, first elastic wall 122 can and expand along with the pressure rising.

On the other hand, on the opposite face of the outer wall 130 of water tank 112 and first elastic wall a pair of contact switch 140 is arranged.Therefore, if water tank 112 internal pressures rise, risings of also can expanding of first elastic wall, contact switch 140 links to each other and sends " startup on " signal.In case contact switch 140 sends signal like this, control tool (not shown) will be received signal, stops the operation of heater 114, prevents that water tank 112 internal pressures from continuing to rise.

The steam raising plant 110 of present embodiment can be adjusted the material of first elastic wall 122, perhaps can regulate the outer wall 130 of installation contact switch 140 and the distance between first elastic wall 122, regulates the pressure that contact switch 140 sends signal then.Promptly the material of first elastic wall 122 will adopt the higher elastic material of coefficient of elasticity to make, or improves the pressure that links to each other with contact switch 140 by the distance of widening between the outer wall 130 and first elastic wall 122.
