60 service life of stick.
Some optional examples according to the present invention, coaming plate 70 are equipped with control valve, and control valve is configured to fill when pressure stabilizing
Unlatching when setting 100 in nominal situation is closed when stable-pressure device 100 is in emptying operating condition.It can guarantee heating rod in this way
60 is exposed, while avoiding dry combustion method, allows the water in water storage part 50 and between the water in shell 10 to a certain extent
Mutually circulation.
Other embodiments according to the present invention are connected with installing pipe at least one mounting hole 32, one of heating
Stick 60 may be mounted in installing pipe, for example, installing pipe can be extended downwardly along the vertical direction of shell 10, it can also be along shell
10 vertical direction tilts down extension, in this way, installing pipe forms water storage part 50, when 100 dehydration of stable-pressure device emptying, due to
Water is still stored in the water containing chamber of installing pipe, this way it is possible to avoid heating rod 60 is completely exposed and dry combustion method is caused to damage, thus
Realize the lasting pressure stabilization function of stable-pressure device 100.
Other embodiment according to the present invention, drainpipe 40 is connected with discharge outlet 31 and drainpipe 40 is at least partly worn
Discharge outlet 31 is crossed to enter inside shell 10, into shell 10 in form water storage between drainpipe 40 not and the internal perisporium of shell 10
Portion 50, this is, the open side height of water storage part 50 is equal with the most significant end of drainpipe 40, when 100 dehydration of stable-pressure device emptying,
Heating rod 60 in water storage part 50 still may be at the soaking state of water, cause dry combustion method to be damaged so as to avoid exposed
It is bad, and then realize and continue pressure stabilization function.
Other embodiment according to the present invention, water storage part 50 are formed as closed cavity, and heating rod 60 is set to water storage part 50
It is interior, and water storage part 50 by pipeline connection to end socket (such as upper cover 20 or lower head 30) or shell 10, as a result, will be steady
Pressure device 100 is set as split type structure, it is possible to reduce changes to the structure of 100 shell 10 of stable-pressure device, so that when pressure stabilizing fills
After setting 100 emptying dehydrations, has no effect on heating rod 60 and continue heating work, pressure needed for maintaining stable-pressure device 100.
In some examples of the invention, the part positioned at water storage part 50 of shell 10 there is cross-sectional area to increase prominent
Expand structure, in this way, to a certain extent, heating rod 60 can be made to be less susceptible to exposed, and can use and increase shell 10
Cross-sectional area, and then increase the volume of 60 top water area of heating rod.
In some optional examples of the invention, heating rod 60 can be vertical heating rod 60, consequently facilitating assembly, another
In some examples, heating rod 60 can be Horizontal Heating stick 60 or tilting heating rod 60, in this way, can make heating rod 60
