Description
【Technical field】
Patent of the present invention is related to a kind of frost 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
When being filled with cold water in state, water circuit system, if whole machine installation is poured in down a chimney in cold balcony or extraneous cold wind by smoke exhaust pipe formation, it can lead
Pyrogenicity hydrophone internal temperature rapid drawdown, easily occurs pipeline bursting by freezing and leak.The antifreezing measures generally used at this stage have three kinds：
One is to use safety valve, i.e., when not in use empty Water route system of water heater, and the method can be effectively antifreeze but easy
There is pipeline bursting by freezing because user forgets；
Two be to use electric heating assembly, can perceive water route temperature by temperature controller, when it is less than closing point temperature, heating
Component carries out more comprehensively quick heating to water circuit system, and this method antifreezing effect is also the antifreeze of main flow at this stage preferably
Measure, but the component power, typically in 90W or so, the power consumption worked when long is larger, is calculated by 8 year service life, electric auxiliary heat
Operation cost at 600 yuan or so, cost is higher and hidden danger that can not be worked in the presence of having a power failure；
Three be to set up anti-down airduct, i.e., increase anti-down wind pipe component between smoke exhaust pipe and water heater, and cigarette is ensured with check valve
Extraneous 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 use rubber seal scheme in design of Sealing Structure more, but rubber seal reliability is low, no
Wear-resisting and easy aging, is chronically at slip and squeezed state, 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.
