Description
【Technical field】
The utility model patent is related to a kind of novel anti-freezing valve.
【Background technology】
In northern China overwhelming majority area, the temperature in winter is generally less than 0 DEG C.When gas heater is in inoperative shape
State, when being filled with cold water in water circuit system, pour in down a chimney if whole machine installation is formed in cold balcony or extraneous cold wind by smoke exhaust pipe, can lead
Pyrogenicity hydrophone internal temperature rapid drawdown, pipeline bursting by freezing and leak easily occurs.The antifreezing measures generally used at this stage have three kinds：
First, using safety valve, i.e., Water route system of water heater is emptied when not in use, the method can be effectively antifreeze but easy
There is pipeline bursting by freezing because user forgets；
Second, using electric heating assembly, water route temperature can be perceived by temperature controller, when it is less than closing point temperature, heating
Component carries out more comprehensive quick heating to water circuit system, and this method antifreezing effect is preferable, and main flow at this stage is antifreeze
Measure, but the component power, typically in 90W or so, the power consumption to be worked when long is larger, is calculated by 8 year service life, the auxiliary heat of electricity
Operation cost at 600 yuan or so, cost is higher and in the presence of the hidden danger that can not work of having a power failure；
Third, setting up anti-down airduct, i.e., increase anti-down wind pipe component between smoke exhaust pipe and water heater, cigarette is ensured with check valve
External world's cold wind can not be entered inside water heater by smoke pipe while gas is smoothly discharged, the method prior art it is more ripe and
The generation of water heater freezing accident can be significantly reduced, but this method is only to prevent cold wind from pouring in down a chimney, and cold sun is arranged on for water heater
The situation of platform is typically used in combination without positive effect with this method with above two kinds.
Prior art uses rubber seal scheme more in design of Sealing Structure, but rubber seal reliability is low, no
It is wear-resisting and easy to aging, slip and squeezed state are chronically at, is easily failed because of aging.And in rubber seal scheme, often
Need to design enough support frames for rubber, add integrally-built complexity, further reduce reliability.
Due to above mentioned problem be present, it is necessary to solution is proposed to it, the utility model is exactly in this context
Make.
