Abstract
The utility model discloses a heat exchanging set which comprises a heat exchanger, a water circulation unit and a water replenishing unit. The water replenishing unit is provided with two to three water replenishing pipelines, each of the water replenishing pipelines comprises a water replenishing pump, a valve and a pipeline, one of the water replenishing pipelines is provided with a connection hose, and the pipelines on the two sides of the connection hose are provided with stop valves. By means of the heat exchanging set with the structure, when temperature of water in heating pipelines rises to generate the heat-expansion and cold-contraction effect, one end of the connection hose can be disconnected conveniently to discharge backflow water and release the water pressure in the heating pipelines, and potential safety hazards produced due to the rising of the water pressure in the heating pipelines can be prevented effectively.
Description
Technical field
The utility model relates to a kind of heat exchange unit, especially relates to a kind of heat exchange unit that comprises heat exchanger, water circle device and water replanishing device.
Background technology
The heat exchange unit of present heating system mainly comprises heat exchanger, water circle device and water replanishing device; A thermal source water inlet forms a thermal source backwater as thermodynamic medium through heat exchanger and after as the secondary heating water supply heat exchange of cold working media, the secondary heating water supply secondary heating backwater that formation temperature raises after heat exchange.The power resources that form secondary heating backwater after the secondary heating water supply heat exchange are in water circle device, and water circle device has provides the water circulating pump that forms secondary heating backwater after the secondary heating water supply heat exchange.Water replanishing device has 2-3 bar water pipe, and every water pipe comprises small pump, valve and pipeline, and water replanishing device links to each other with the demineralized water pipeline, and when in the secondary heating pipeline during lack of water, being fetched water from the demineralized water pipeline by water replanishing device covers in the heating pipeline.Demineralized water pipeline in present a lot of heating systems is provided with check valve; Be that demineralized water can only flow to heating pipe and can not flow to the demineralized water pipeline through water replanishing device by heating pipe through water replanishing device from the demineralized water pipeline; Can produce the effect of expanding with heat and contract with cold when but the water temperature in the heating pipeline raises sometimes; Water can take place by the situation that flows to the demineralized water pipeline in the heating pipeline through water replanishing device; Water can't flow to the demineralized water pipeline if the demineralized water pipeline is provided with check valve, causes heating pipeline hydraulic pressure too high, and there is potential safety hazard in the heating pipeline.
The utility model content
The technical problem that the utility model will solve provides a kind of can not causing the heating pipeline because of hydraulic pressure is too high and damages and then have a heat exchange unit that the heating pipeline in the heating system is had protective effect.
For solving the problems of the technologies described above; A kind of heat exchange unit of the utility model; Comprise heat exchanger, water circle device and water replanishing device, water replanishing device has 2-3 bar water pipe, and every water pipe comprises small pump, valve and pipeline; The pipeline of a water pipe in the said 2-3 bar water pipe has the connection flexible pipe, and this connection flexible pipe pipelines on two sides is provided with stop valve.
Adopt the heat exchange unit of said structure; Because the pipeline of a water pipe of water replanishing device has the connection flexible pipe, and this connections flexible pipe pipelines on two sides is provided with stop valve, so the demineralized water pipeline of working as in the heating system is provided with check valve; Demineralized water can only be from the demineralized water pipeline flows to heating pipe through water replanishing device and can not be by heating pipe when water replanishing device flows to the demineralized water pipeline; Water temperature in running into the heating pipeline raises and produces when expanding with heat and contract with cold effect, can break off an end that connects flexible pipe easily, discharges the water that refluxes; Hydraulic pressure in the venting heating pipeline can be avoided in the heating pipeline potential safety hazard because of hydraulic pressure rising industry effectively.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done to specify further.
Fig. 1 is the pipeline jointing construction sketch map of a kind of heat exchange unit of the utility model in heating system.
Fig. 2 is the pipeline structure enlarged diagram of the water replanishing device of a kind of heat exchange unit of the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2; A kind of heat exchange unit of the utility model; Comprise heat exchanger 1, water circle device 2 and water replanishing device 3, water replanishing device has 2-3 bar water pipe, and every water pipe comprises small pump 4, valve 5 and pipeline 6; The pipeline 6 of a water pipe in the said 2-3 bar water pipe has the flexible pipe 7 of connection, and this connection flexible pipe pipelines on two sides is provided with stop valve 8.When a kind of heat exchange unit of the utility model moves in heating system; The water inlet 11 of thermal source forms a thermal source backwater 12 as thermodynamic medium after heat exchanger 1 and 13 heat exchange of supplying water as the secondary heating of cold working media; The secondary heating water supply 13 secondary heating backwater 14 that formation temperature raises after heat exchange, water replanishing device 3 links to each other with demineralized water pipeline 15.
