Abstract
The utility model discloses a kind of high-temperature bearing hot-water heating system level pressure to expand water replanishing device, including cooling surge tank, expansion drum, nitrogen-making device, constant pressure supply water pump, replenisher tank；Cooling surge tank is connected to the bottom of expansion drum, which is pumped by constant pressure supply water be connected to replenisher tank simultaneously；It is connected at the top of expansion drum with nitrogen-making device, upper and lower position has liquid-level switch inside the expansion drum.The utility model can solve how in 100 degree or more of high temperature water heating system also it is ensured that the technical problem of pipeline safety.
Description
Technical field
The utility model relates to a kind of level pressure that hot-water boiler uses to expand water replanishing device.
Background technique
In closed-loop water system, water heating temperature is increased, and volume will increase, constantly increase so as to cause system pressure
Add.Specified leaving water temperature limitation when due to design, it would be desirable to which default is within the scope of certain pressure.More than this pressure model
It encloses, we want pressure release to guarantee pipeline safety.In 100 degree of hot-water heating systems below, we are by the way of bellows expansion drum
Level pressure, but in 100 degree or more of high temperature water heating system, since the ability to bear of leather bag in bellows expansion drum limits, and it is uncomfortable
Close bellows expansion drum.
Utility model content
The purpose of the utility model is to provide a kind of high-temperature bearing hot-water heating system level pressure to expand water replanishing device, and how is solution
Also it is ensured that the technical problem of pipeline safety in 100 degree or more of high temperature water heating system.
High-temperature bearing hot-water heating system level pressure expands water replanishing device, including cools down surge tank, expansion drum, nitrogen-making device, determines
Press small pump, replenisher tank；Cooling surge tank be connected to the bottom of expansion drum, the cooling surge tank simultaneously by constant pressure supply water pump and
Replenisher tank connection；It is connected at the top of expansion drum with nitrogen-making device, upper and lower position has liquid-level switch inside the expansion drum.
The constant pressure supply water pump shares two composition juxtapositions and is arranged between expansion drum and replenisher tank.
Also there is solenoid valve between the expansion drum and replenisher tank.
The beneficial effects of the utility model are: cooling surge tank and expansion drum play the role of absorption system swell increment, mend
Water pot and positioning small pump play the role of replenishment system water, and nitrogen-making device plays supplement nitrogen.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
1. cooling surge tank, 2. expansion drums, 3. nitrogen-making devices, 4. small pumps, 5. replenisher tanks, 6. electromagnetism in figure
Valve, 7. liquid-level switches.
Detailed description of the invention
Referring to FIG. 1, high-temperature bearing hot-water heating system in figure level pressure expands water replanishing device, including it is cooling surge tank 1, swollen
Swell 2, nitrogen-making device 3, constant pressure supply water pump 4, replenisher tank 5.Cooling surge tank 1 uses diaphragm type surge tank, the cooling surge tank 1
For existing tank body；Expansion drum 2 is also exploited with existing expansion drum 2；Existing nitrogen-making device 3 can be used in nitrogen-making device 3；Constant pressure supply water
Existing configuration can also be used in the cooperation of pump 4 and replenisher tank 5.
Cooling surge tank 1 be connected to the bottom of expansion drum 2, the cooling surge tank 1 simultaneously by two groups of constant pressure supply waters pump 4 and
Replenisher tank 5 is connected to；2 top of expansion drum is connected to nitrogen-making device 3, which has liquid-level switch 7.For
Facilitate control, can redesign a solenoid valve 6 between expansion drum 2 and replenisher tank 5.
The working principle of this equipment is: before system brings into operation, cooling surge tank 1 is full of water, and 2 water level of expansion drum is located at tank
At body lowest water level, when system brings into operation, the high-temperature water of the high-temperature water of expanded by heating i.e. 100 degree Celsius or more is squeezed by pipeline
It is pressed into cooling surge tank 1, cooling surge tank 1 can buffer impact of the hot water to valve pipeline, can also reduce to a certain degree
Hot water temperature.The water come out from cooling surge tank 1 travels further into expansion drum 2, and the water level in expansion drum 2 rises at this time, swollen
The nitrogen on 2 top of swell is extruded away, is discharged by pressure reducing valve, so that the pressure in pipe-line system be made to be maintained at default
Pressure limit in i.e. pressure reducing valve pressure limit.When the water level in expansion drum 2 is higher than peak level in expansion drum 3, liquid level
7 signal communication of switch, small pump 4 are started to work, until water level and pressure reach lower limit and refer to, when system operates normally, expansion drum 2
Water level is between lowest water level and peak level.
To keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, above in conjunction with the utility model
Attached drawing in embodiment clearly and completely describes the technical scheme in the embodiment of the utility model, it is clear that retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.
Therefore, the above detailed description to the embodiments of the present invention provided in the accompanying drawings is not intended to limit requirement
The scope of the utility model of protection, but it is merely representative of the selected embodiment of the utility model.Based in the utility model
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the range of the utility model protection.
