Technical solution and its benefits are clearer.It describes embodiment below with reference to attached drawing to be exemplary, it is intended to solve
The present invention is released, and is not considered as limiting the invention.
As shown in Figure 1 and Figure 2, a kind of gas and hot water equipment of band expansion gas tank, comprising: combustion chamber 3 is arranged described
Burner 4, heat exchanger 2 in combustion chamber 3, and the water supply line being connect with the heat exchanger 2；It is characterized in that,
Expansion gas tank 1 is connected on the combustion chamber 3, the expansion gas tank 1 includes: cabinet and is arranged in the intracorporal bullet of the case
The inner cavity of the cabinet is separated into combustion gas chamber 9 and precharge of gas chamber 7, the combustion gas by property film 8, the elastic film 8
Chamber 9 is connected to the combustion chamber 3, is pre-charged with gas in the precharge of gas chamber 7.
Wherein, the elastic film 8 is high-temperature resistant rubber film, such as fluorubber film.
The expansion gas tank 1 is made of high temperature resistant elastic material, such as thermoplastic elastomer (TPE) TPE or fluorubber.
The precharge of gas chamber 7 is equipped with the gas supply port 6 for inflation, and the gas supply port 6 is equipped with can
The lid of disassembly, the lid being such as connected through a screw thread, the lid connected by pluggable mode.
Preferably, the connection being equipped on the combustion gas chamber 9 for being connected to the combustion gas chamber 9 and combustion chamber 3 is logical
Road 10.
The gas is one or more of nitrogen, air, inert gas.
It is further preferred that the gas and hot water equipment with expanding baloon further includes shell, the combustion chamber 3 and institute

Portion.
Blower 5 is connected on the combustion chamber 3.
The gas and hot water equipment is gas heater or burnt gas wall hanging furnace.
Combustion gas chamber 9 is connected to the combustion chamber 3 of water heater, and pressure is equal to pressure in combustion chamber 3 in combustion gas chamber 9,
When water heater shifts gears burning or unstable gaseous-pressure, pressure generates variation in combustion chamber 3, and pressure acts on expansion gas tank
On 1 elastic film 8, elastic film 8 in precharge of gas chamber 7 preliminary filling gas generate active force, show compression or
Stretching chamber volume makes film two sides to reach a new dynamic equilibrium, stablizes combustion chamber pressure, guarantees flameholding.
For example burn from low-grade variation in combustion to top grade, combustion gas sharply increases, and 3 pressure of combustion chamber becomes larger, the pressure of increase
Power can act on elastic film 8, compress precharge of gas chamber 7, it is ensured that more gases and pressure can be accommodated, to reach new
Balance.After pressure reduces in combustion chamber 3, the gas meeting elasticity of compression film 8 of preliminary filling is mobile to combustion gas chamber 9, reaches
Until equalization point.Therefore, no matter how combustion chamber room pressure changes, by expanding gas tank 1, it is made to be held in a balance
State.Expand gas tank can only pressure in balance combustion cavity indoor pressure a period of time jumpy, for entire burned
3 pressure balance of combustion chamber effect in journey is unobvious.
