Description
Technical field
The present invention relates to gas heater technical field more particularly to condensing type water heaters.
Background technology
Existing condensing gas-fired fast water heater, condensing heat exchanger mostly welds to form seal cavity using metal plate, close
Flue gas flow channel design is carried out again in envelope cavity, is limited to the formability of metal plate, and flue gas flow channel cannot be excessively complicated, therefore, greatly
After partial condensation heat exchanger enters condensing heat exchanger using flue gas at present, enter heat exchange from condensing heat exchanger lower part of the housing space
Device, flue gas are expelled directly out after heat exchanger exchanges heat, but flue gas can generate condensed water to the cold in heat transfer process, and condensed water is along changing
Hot face is dripped along gravity direction, when condensed water drippage direction is opposite with flue gas flow direction, easily forms liquid film, flue gas in heat-transfer surface
It cannot directly be contacted with heat-transfer surface, the heat exchange efficiency of heat exchanging body certainly will reduce.Furthermore the existing common aluminum heat exchanging body of shell-and-tube
It passes in and out water swivel to weld using aluminium and heat exchanging body, during using aluminum condensing heat exchanger, between metal shell and heat exchanging body easily
Potential difference is generated, causes heat exchanging body electrochemical corrosion phenomenon serious, easily causes condensing heat exchanger leak, this phenomenon is in China
The poor region of water quality, such as northwest and northeast and Basin of Huaihe River, performance is especially prominent, finally high using corrosion resistance
As heat exchanging body base material, the program shows preferably stainless steel material in terms of corrosion resistance, but stainless steel to be fabricated to it is closed
Space, it is necessary to weld means realization, including heat exchanging body welding and case weld, technology ensuring is more demanding, and because weld seam is deposited
In impurity, weld stress is more concentrated, and easily becomes the weak link of condensing heat exchanger.

Referring to Figure 30-32, water outlet connector 9 is identical with the structure of water supply connector 8 in the present embodiment, now with water outlet connector 9
For illustrate its structure, set on water outlet connector 9 there are three seal groove, be the first seal groove 90,92 and of the second seal groove respectively
Third seal groove 94, wherein the first seal groove 90, the second seal groove 92 are arranged at the water outlet Y of connector 1, and third seal groove
94 are arranged at the water inlet end X of connector 1, and the first seal groove 90, the second seal groove 92 and third seal groove 94 are circle.
Stop flange 91 is equipped between one seal groove 90 and the second seal groove 92, connection is additionally provided at the water inlet end X of water outlet connector 9
Flange 93.It is convex in first flange and second in the first flange and the second flange that the second seal groove 92 includes being arranged in parallel
Edge is equipped with reinforcing rib between the ontology respectively.The reinforcing rib set between the first flange and water outlet connector 9 also with it is described
Stop flange 11 connects, and reinforcing rib can increase the intensity of entire connector.
When water outlet connector 9 is installed, do not shown in figure with the water inlet end X of water outlet connector 9 water inlet pipes connecting.This
Field technology personnel prevent from letting out at condenser Inlet and outlet water it will be appreciated that third seal groove 94 is sealed with water inlet pipe by sealing ring
Leakage, and connecting flange 93 ensures that the sealing ring in third seal groove 94 begins by clamp spring or the flange screw of bolt and water inlet pipe
Sealing state is kept eventually.What is connect with 1 water outlet Y of connector is the water outlet 302 of the lower water seal cover 3 of heat exchanging body 4, the first seal groove
90 are sealed with the water outlet 302 of lower water seal cover 3 by the first sealing ring 95, prevent from leaking at 4 Inlet and outlet water of heat exchanging body.Second sealing
Slot 98 and the housing 1 of person's condensing heat exchanger are sealed by the second sealing ring 98, prevent condensed water or flue gas from being leaked from condenser,
Cause danger.The supporting surface for the housing 1 that the stop flange 91 passes through condensing heat exchanger is supported and in installation condition
It is adjacent to 1 supporting surface of housing and lower 3 supporting surface of water seal cover, ensures the first sealing ring 95 and the second seal groove of the first seal groove 90
92 the second sealing ring 98 remains sealing state.
Referring again to Fig. 1-6, after petticoat pipe 2 is connect with housing 1, smoke chamber 11 is led under housing 1 with leading smoke chamber on petticoat pipe 4
200 correspond to.Housing seal item 6 is equipped between petticoat pipe 2 and housing 1, housing seal item 6 is arranged on petticoat pipe seal groove 33 and petticoat pipe
In seal groove 23, shape is identical with the shape of petticoat pipe 2 and is substantially in "U" shaped.It is installed in the heat exchanging chamber 10 of housing 1
Have a heat exchanging body 4, the cylindrical diversion division 21 of petticoat pipe 2 is inserted among the exhaust gases passes 408 of heat exchanging body 4, the support column 24 of petticoat pipe 2 with
Heat exchanging body 4 connects, and plays support and positioning function.Referring to Fig. 6, thick dashed line represents the flow direction of flue gas in figure, and heavy line represents condensation
The flow direction of water after flue gas enters condensing heat exchanger from main heat exchanger, is led in smoke chamber 11 under housing flow up first, into
Enter petticoat pipe 2 on lead smoke chamber 200, since diversion division 21 can guide flue gas flow direction, flue gas can be flowed along diversion division 21, i.e. cigarette
Gas can only be flowed from the top down of condensing heat exchanger, ensure during heat exchange flue gas flow direction and condensation flow to consistent, so heat exchange
The heat-transfer surface of body is just not easy to form liquid film, also just improves the heat exchange efficiency of condensing heat exchanger, after the completion of flue gas heat exchange, flue gas
Enter the exhaust smoke hole of diversion division 21 from 4 bottom of heat exchanging body, discharge condensing heat exchanger, independently arranged exhaust smoke hole increases condensation and changes
The smoke extraction area of hot device.At the same time flow enters heat exchanging body 4 from water supply connector 8, (the axis side of heat exchanging body 100 upward first
To) from the water inlet 303 of lower water seal cover 300 into intake chamber 307, flow divides twice in intake chamber 307, flows into heat exchange together
First water inlet water flow passage 101 of body 100, another road flow into the second water inlet water flow passage 102 of heat exchanging body 100, when flow is from first
When water flow passage 101 of intaking flows into the first water-carrying groove 503 of upper gas sealing lid 500, flow can flow under the limitation of the first water-carrying groove 503
Into the first water outlet water flow passage 104.Identical, cross water when flow flows into the second of upper gas sealing lid 500 from the second water inlet water flow passage 102
During slot 504, flow can flow into the second water outlet water flow passage 103 of heat exchanging body 100 under the limitation of the second water-carrying groove 504, work as twice
Flow is discharged (the axis side of heat exchanging body 100 downwards of water flow passage 103 from the first water outlet water flow passage 104 and second of heat exchanging body 100
To) flow into the effluent trough 306 of lower water seal cover 300 after, twice flow collaborates one of flow again, is finally flowed out from water outlet 302, most
It is flowed out eventually from water outlet connector 9.During flow flowing and flow of flue gas, flow and flue gas have sufficient room and time into
Row heat exchange, improves heat exchange efficiency.
