Description
Technical field
The present invention relates to gas furnace and control technical field, particularly a kind of high energy efficiency gas furnace condensate water level protection device
And there is its gas furnace.
Background technology
What the single pressure tap mode of existing gas furnace condensate water level protection device use was tested is that internal pressure is with air
Pressure reduction between pressure, the most single pressure tap is connected with pressure-head switch, when condensed water covers pressure tap, although water can seal
A part of air pressure, the most still can transmit a part of pressure, thus when water level just above pressure tap when pressure switch also
Will not protect, pressure switch is in protection and the critical point do not protected, and the critical point causing combustion gas to be also at off and on comes
Echo moves, and period burning CO can raise rapidly, causes potential safety hazard；Meanwhile, the pressure within combustion system is due to fired state
And other reasons has difference, internal pressure can be caused inaccurate with the pressure reduction between atmospheric pressure, it is possible to there will be one
A little fluctuations and the situation of abnormal protection.
Summary of the invention
