Position flange.In the technical scheme, the water hole be through-hole, the water hole connecting tube and heat exchanging body is connected so that
Water flow can free in and out condenser, first seal groove and water seal cover and be sealed by sealing ring, prevent heat exchanging body Inlet and outlet water
The shell of place's leakage, second seal groove and water heater or condenser is sealed by sealing ring, prevents condensed water or flue gas
It is leaked from water heater or condenser, causes danger.The stop flange passes through water heater or the shell of condenser
Supporting surface is supported and is adjacent in installation condition and shell supporting surface and water seal cover supporting surface, guarantees the sealing of the first seal groove
The sealing ring of circle and the second seal groove remains sealing state.
Further, the water inlet end of the ontology is provided with third seal groove.The third seal groove and connecting tube are logical
Sealing ring sealing is crossed, prevents from leaking at condenser Inlet and outlet water.
Further, the water inlet end of the ontology is provided with connecting flange.The connecting flange passes through circlip or bolt
With connecting tube flange screw, guarantee that the sealing ring in third seal groove remains sealing state.
Further, first seal groove, the second seal groove and third seal groove are circle.Circular seal groove can be with
Connecting tube and sealing ring preferably cooperate.
Further, second seal groove includes the first flange and the second flange disposed in parallel, convex described first
Edge, the second flange are equipped with reinforcing rib between the ontology respectively.What is be arranged between first flange and the ontology adds
Strengthening tendons are also connect with the stop flange.Reinforcing rib can increase the intensity of entire connector.
Further, the connector is made of fire-retardant and high-temperature resistance plastice.Connector uses fire-retardant and high-temperature resistance plastice system
It makes, one-pass molding and corrosion-resistant, the high reliablity of energy.
Compared with prior art, the utility model has the beneficial effects that
(1) gas heater in the utility model with connector using three-layer sealed, realize respectively the sealing of heat exchanging body water channel,
Flue gas and condensation water-stop, condenser pass in and out water-stop, guarantee sealing reliability.
(2) gas heater in the utility model is manufactured with connector using high-strength anti-flaming high-temperature resistance plastice, once at
Type and corrosion-resistant, the high reliablity of energy.
(3) the gas heater joint structure in the utility model is simple, reduces manufacturing cost.
