Abstract
The utility model relates to a cooling system preventing a normal-pressure hot-water boiler from being too hot. The cooling system is characterized in that a cooling water pipe penetrates through the top inside a water cover, the inlet of the cooling water pipe is connected with tap water, the outlet of the water pipe is connected with a temperature control switch, and temperature control switch can be turned on or off according to the temperature of the water outlet. The cooling system has the advantages of being safe, efficient, simple in pipeline, convenient to use, low in cost and the like.
Description
Technical field
The utility model belongs to heating equipment technical field, relates to a kind of normal-pressure hot-water boiler technical field, particularly a kind of biomass fuel normal-pressure hot-water boiler technical field.
Background technology
Normal-pressure hot-water boiler is also unpressurized hot water boiler, boiler body is the unpressurized hot water boiler in normal pressure running status all the time, its main feature is exactly not pressure-bearing of boiler, there is no potential safety hazard, be mainly used in for the warm hot water of producing, can heat zonule, can solve central heating fault and cause large area to stop warm problem.But in continuous heating process, water jacket top can form vapor film and constantly strengthen, current most of normal-pressure hot-water boiler all need be provided with atmosphere entry at top, to prevent the pressure of overheated generation, there is the potential danger of superheated steam from atmospheric communicating pipe ejection, prevent overheated measure even if there is boiler to possess, but such measure generally exist hysteresis quality and expense higher, be difficult to large-area popularization.
Summary of the invention
The purpose of this utility model be to provide a kind of prevent from being heated for a long time in boiler water jacket produce pressure cause potential danger overheated cooling system, the utility model is to realize by following technical scheme.
A kind of cooling system that prevents that normal-pressure hot-water boiler is overheated, its water jacket is enclosed in burner hearth surrounding, it is characterized in that described water jacket inner top is penetrated with a cooling water pipe, described cooling water pipe entrance connects running water, pipe outlet place is connected with temperature detect switch (TDS), can open and close according to the temperature signal of boiler water outlet.
Described cooling water pipe is coil-like steel pipe.
Described cooling water pipe outer wall has thread-like structure.
The utility model uses cooling water pipe through water jacket top, high-temperature-hot-water in water jacket is lowered the temperature in its periphery, form condensation, control water temperature, eliminate the steam pressure in water jacket, and adopt temperature detect switch (TDS) automatically to control flowing of cooling water, have safe and efficient, pipeline is simple, easy to use, the feature such as with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation that prevents the overheated cooling system of normal-pressure hot-water boiler of the present utility model.
Fig. 2 is the structural representation of coil-like cooling water pipe.
Fig. 3 is cooling water pipe outer wall thread shape structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Prevent the cooling system that normal-pressure hot-water boiler is overheated, as shown in Figure 1, comprise burner hearth 1 and water jacket 2, water jacket 2 is enclosed in burner hearth 1 surrounding, and water inlet pipe 3 is arranged at the bottom of water jacket 2, and outlet pipe 4 is arranged at top.Fuel is in the interior burning of burner hearth 1, and its heat is absorbed by water jacket 2, and water temperature is raise.Water jacket 2 inner tops are penetrated with a cooling water pipe 5, and this cooling water pipe 5 is coil-like steel pipes, and these cooling water pipe 5 outer walls in water jacket 2 regions are processed with thread-like structure, increase the heat exchange area of cooling water pipe.Cooling water pipe 5 entrances connect running water, exit is connected with temperature detect switch (TDS) 6, this temperature detect switch (TDS) 6 belongs to closed type switch, can open and close according to the temperature signal of boiler water outlet, in the time detecting outlet pipe 4 water outlet temperature and reach overtemperature (getting 95 ℃ in this example), temperature detect switch (TDS) 6 is opened, running water enters cooling water pipe 5, after absorbing heat, discharge from outlet, thereby reach cooling effect, can effectively prevent the generation of superheated steam in normal-pressure boiler; In the time detecting outlet pipe 4 water outlet temperature lower than overtemperature, temperature detect switch (TDS) 6 cuts out, and running water stops entering cooling water pipe 5.
Claims (3)
1. a cooling system that prevents that normal-pressure hot-water boiler is overheated, its water jacket is enclosed in burner hearth surrounding, it is characterized in that described water jacket inner top is penetrated with a cooling water pipe, described cooling water pipe entrance connects running water, pipe outlet place is connected with temperature detect switch (TDS), can open and close according to the temperature signal of boiler water outlet.
2. the cooling system that prevents that normal-pressure hot-water boiler is overheated according to claim 1, is characterized in that described cooling water pipe is coil-like steel pipe.
3. the cooling system that prevents that normal-pressure hot-water boiler is overheated according to claim 1 and 2, is characterized in that described cooling water pipe outer wall has thread-like structure.
