Description
Technical field
The present invention relates to a kind of automatic compensation conduits, and in particular to a kind of automatic compensation conduit of medium and solar energy heat conducting pipe
Road.
Background technique
Existing plate pressure-bearing formula solar energy heat-transferring medium (anti-icing fluid) heat conductive circulation pipeline, loine pressure are variations
, increase as the temperature rises；Therefore, most of producer uses pressure expansion tank, top exhaust valve, pipeline pressure at this stage
The components such as power valve, come variations in line pressure caused by adjusting because of circulation line heat-conducting medium (anti-icing fluid) temperature change.
And exist simultaneously heat transfer medium (anti-icing fluid) and defect be easily lost, such as: 1., temperature increase when, loine pressure increase
Greatly, each interface easily reveals heat transfer medium (anti-icing fluid).2., top exhaust valve operation when heat transfer medium (anti-icing fluid) easily a small amount of row
Except out.
After heat transfer medium (anti-icing fluid) loss, expansion drum can have a small amount of compensation, compensate for not after expansion pressure tank release
?.There is vacuole because lacking heat transfer medium (anti-icing fluid) in circulation line, will lead to and follows bad system operation irregularity, or even not work
Make, substantially reduce heat-conducting effect, causes the reduction of solar energy heating efficiency.
Under normal condition, solar energy is mounted on roof, and it is extremely inconvenient to be regularly maintained, and increases use cost indirectly.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of balance overpressure, automatic compensation pipes
The pipeline of interior medium.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of automatic compensation conduit of medium, main line is the closure pipeline of series circulation pump, by bye-pass, in circulating pump into
Mouth end and outlet end parallel connection fluid reservoir；And the bye-pass of outlet end is equipped with closure valve.
Above-mentioned fluid reservoir is gerotor type fluid reservoir.
Above-mentioned fluid reservoir connects sealant supplement cylinder；It is equipped with liquid level sensor in fluid reservoir, controls the solenoid valve of feed tank fluid infusion.
A kind of solar energy heat conducting pipeline, in main line and main line including a kind of above-mentioned automatic compensation conduit of medium
Concatenated solar heat-collection plate and water tank pass through the heat transfer medium transferring heat energy in main line.
Solution in above-mentioned fluid reservoir includes: heat transfer medium, anti-icing fluid.
It is respectively equipped in main pipeline at above-mentioned solar heat-collection plate and in water tank the temperature sensing connecting with control device
Device, control device drive circulating pump according to temperature difference.
The invention has the beneficial effects that:
Closed main line is changed to open type pipeline by the automatic compensation conduit of a kind of medium of the invention, when operation at circulation line
It can be discharged from branch (input end) in the minute-pressure state provided by circulating pump because of the liquid expansion that heat transfer medium heating generates, when
After temperature reduces or swelling disappears, then there is circulation to be pumped back to and fill into, keeps the heat transfer medium in main line to be constantly in and fill
It is full of state；The loss of heat transfer medium after long-time use can also be pumped back to by circulation and be filled into；Solve overpressure balance,
And the defect that heat transfer medium compensation is difficult；Compared with prior art, the components such as top exhaust valve, expansion drum and pressure valve are eliminated,
Production cost is reduced, the failure rate of operation is greatly reduced, reduces the phenomenon of the failure and maintenance cost of later maintenance, is improved
The collecting efficiency of solar energy has very strong practicability and wide applicability.

Fig. 1 is a kind of structural schematic diagram of solar energy heat conducting pipeline of the invention.
Attached meaning marked in the figure is as follows: 1, main line, 2, bye-pass, 3, circulating pump, 4, collecting plate, 5, water tank, and 6, close
Close valve, 7, fluid reservoir, 8, liquid level sensor, 9, solenoid valve, 10, feed tank.
Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
A kind of solar energy heat conducting pipeline is made of, circulating pump the concatenated solar heat-collection plate of main line, water tank, circulating pump
Heat transfer medium in driving main line circulates transferring heat energy.
It is respectively equipped in main pipeline at solar heat-collection plate and in water tank the temperature sensor connecting with control device,
Control device drives circulating pump according to temperature difference.
As shown in Figure 1, the automatic compensation conduit of medium of the invention, by accessing main line, and and circulating pump by bye-pass
Gerotor type fluid reservoir in parallel is constituted, the input end and the main line after solar heat-collection plate that access port is respectively placed in circulating pump
(outlet end), and the bye-pass of outlet end is equipped with closure valve.
Fluid reservoir also connects sealant supplement cylinder；It is equipped with liquid level sensor in fluid reservoir, controls the solenoid valve at the fluid infusion of feed tank.
According to the period and season used, the solution in fluid reservoir and sealant supplement cylinder includes: heat transfer medium, anti-icing fluid.
In use, bye-pass is kept to be immersed in the solution in fluid reservoir, control device is according to the temperature of temperature sensor
Difference opens circulating pump, and the heat transfer medium in main line circulates transferring heat energy.It is filled since the heat transfer medium in main line is in
Full state, therefore, under normal circumstances, the solution in fluid reservoir will not be pumped into main line by circulation, and through a long time makes
With rear, heat transfer medium or anti-icing fluid loss, for example, loine pressure increases when temperature increases, each interface reveals heat transfer medium
(anti-icing fluid)；Prevent there is capacity gap, then circulation is pumped into molten in the fluid reservoir of part from being full of main line in heat transfer medium
Liquid is filled.
It uses for a long time in order to prevent, the solution evaporation or usage amount in fluid reservoir are excessive, lead to the solution in fluid reservoir
Liquid level face be lower than branch junction, circulating pump cannot be pumped into solution in time, or be pumped into air；When the liquid level in fluid reservoir is lower than one
When determining height, control device controls the fluid infusion that solenoid valve opens feed tank, storage is replenished in time according to the feedback of liquid level sensor
Amount of solution in flow container.
Gas is generated if long-play, in main line or needs replacing whole heat transfer mediums, openable closure valve, row
The heat transfer medium of gas or whole in empty main line, required new medium are pumped into supplement by circulating pump out of fluid reservoir.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
