Waste gas after heat exchange exists inside blast pipe jointly, and prior art is a kind of siphon trap type drainage arrangement, and it includes carrying one
The drainpipe of trap, is connected in flue, and caused condensed water is discharged along drainpipe after wall-hung boiler exchanges heat, and is deposited
Condensed water in water is curved can block flue gas, prevent flue gas from getting in.But when trap or drainpipe block,
Condensed water can not discharge from trap, and wall-hung boiler continues to operate, and condensed water will be full of drainpipe until flowing backwards meeting wall-hung boiler
In annular seal space, this may cause wall-hung boiler damage or even threaten personal safety.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided it is a kind of it is reasonable in design,
The condensed water supervising device for wall-hung condensing gas furnace simple in construction, that condensed water elimination can be monitored.
Technical scheme is used by the utility model：The utility model includes condensed water monitoring blast switch, passes through wind
Fan monitoring blast switch that signal wire and the condensed water monitoring blast switch that compresses switch are connected, by tracheae and the blower fan
Monitor the blast switch blower fan being connected and the B-grade condensation heat exchanger being connected with the blower fan, the B-grade condensation heat exchange
Smoke inlet, exhanst gas outlet and discharge outlet are provided with device, the smoke inlet is connected with the exhaust opening of the blower fan, described
Exhanst gas outlet is communicated to outside wall-hung boiler, and threeway, two other port point of the threeway are connected with below the discharge outlet
The first drainpipe and pressure pipe are not connected with, and the pressure pipe is connected with condensed water monitoring blast switch.
Further, the junction of the condensed water monitoring blast switch and the pressure pipe offers relief hole.
Further, the lower end of the drainpipe is connected with water seal, and the water seal includes trap and the second drainpipe, institute
The second drainpipe is stated with the trap to be connected.
The beneficial effects of the utility model are：Include condensed water monitoring blast switch because the utility model uses, pass through
Fan monitoring blast switch that blast switch signal wire and the condensed water monitoring blast switch are connected, by tracheae and the wind
Blower fan that machine monitoring blast switch is connected and the B-grade condensation heat exchanger being connected with the blower fan, the B-grade condensation change
Smoke inlet, exhanst gas outlet and discharge outlet are provided with hot device, the smoke inlet is connected with the exhaust opening of the blower fan, institute
State exhanst gas outlet to be communicated to outside wall-hung boiler, threeway, two other port of the threeway are connected with below the discharge outlet
The first drainpipe and pressure pipe are connected to, the pressure pipe is connected with condensed water monitoring blast switch, so, when
When first drainpipe blocks, the condensed water monitoring blast switch can disconnect automatically, so that the fan monitoring
Blast switch disconnects, and wall-hung boiler is stopped, and prevents that machine breakdown can be caused in wall-hung boiler annular seal space by condensing aqueous reflux.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, in the present embodiment, the utility model includes condensed water monitoring blast switch 1, passes through blast switch
Fan monitoring blast switch 3 that signal wire 2 and the condensed water monitoring blast switch 1 connects, by tracheae 4 and blower fan prison
The control blower fan 5 being connected of blast switch 3 and the B-grade condensation heat exchanger 6 being connected with the blower fan 5, the B-grade condensation change
Smoke inlet, exhanst gas outlet and discharge outlet are provided with hot device 6, the smoke inlet is connected with the exhaust opening of the blower fan 5,
The exhanst gas outlet is communicated to outside wall-hung boiler, is connected with threeway 7 below the discharge outlet, the threeway 7 two other
Port is connected to the first drainpipe 8 and pressure pipe 9, and the pressure pipe 9 is connected with condensed water monitoring blast switch 1
Connect.
In the present embodiment, the junction of the condensed water monitoring blast switch 1 and the pressure pipe 9 offers relief hole
10.The gas in the pressure pipe 9 is discharged in time, prevents that the air pressure in the pressure pipe 9 is excessive, destroys pipeline connection.
In the present embodiment, the lower end of first drainpipe 8 is connected with water seal 11, and the water seal 11 includes trap 12
And second drainpipe 13, second drainpipe 13 are connected with the trap 12.Condensed water is from second drainpipe 13
Discharge, the trap 12 can play a part of blocking flue gas, avoid flue gas from getting in.
Operation principle：
Under normal operating conditions, flue gas caused by wall-hung condensing gas furnace pass through the blower fan 5 after, most of flue gas from
It is discharged in the B-grade condensation heat exchanger 6 outside wall-hung condensing gas furnace, fraction flue gas is passing through the two level hot and cold heat exchanger 6
After be flowed into the pressure pipe 9, make condensed water monitoring blast switch 1 positive-pressure detection port and the negative-pressure detection port it
Between pressure difference reach preset value so that the condensed water monitoring blast switch 1 be kept closed；Flue gas is in the two level
When condensing heat exchanger 6 contacts, a part of condensed water can be produced, condensed water can be provided with from the lower end of B-grade condensation heat exchanger 6
Outside the first drainpipe 8 discharge wall-hung condensing gas furnace of connection.
But when first drainpipe 8 blocks, condensed water can not discharge from first drainpipe 8, cold
Condensate is full of after first drainpipe 8, and condensed water can be flowed at the low level of the pressure pipe 9, and condensed water flows into described take
After pressure pipe 9, the flue gas in the B-grade condensation heat exchanger 6 cannot propagate into the pressure pipe 9, and make the pressure pipe
The air pressure of 9 high levels can not be supplemented, so as to cause the positive-pressure detection port of the condensed water monitoring blast switch 1 to be examined with negative pressure
Default closure pressure difference is unable to reach between survey mouth, the condensed water monitoring blast switch 1 disconnects.Because the condensed water is supervised
Control blast switch 1 is connected by the blast switch signal wire 2 with the fan monitoring blast switch 3, so working as the condensation
When water monitoring blast switch 1 disconnects, the closure signal of the fan monitoring blast switch 3 can not pass through the blast switch signal
Line 2 feeds back, and wall-hung condensing gas furnace is stopped.
The utility model is applied to the technical field of the condensed water supervising device of wall-hung condensing gas furnace.
Although embodiment of the present utility model is described with practical solution, do not form the utility model is contained
The limitation of justice, for those skilled in the art, according to modification of this specification to its embodiment and the group with other schemes
Conjunction will be apparent from.
