The utility model content:
The purpose of this utility model is to provide a kind of regulative mode of stable hydraulic regime, and regulating the secondary net neither influences once net hydraulic regime, does not also change the regulative mode of the hydraulic regime of secondary net.
The utility model is implemented by following technical scheme: a kind of heat supply network heat exchange station secondary net matter regulating system, it comprises heat exchanger, the secondary pipe network water circulating pump, on the secondary net side return pipe of described heat exchanger, be provided with described secondary pipe network water circulating pump, it also comprises secondary net regulating system, described secondary net regulating system comprises control valve and control device, described control valve is a three-way control valve, on the described secondary net side return pipe between described secondary pipe network water circulating pump and the described heat exchanger, be provided with described three-way control valve, described three-way control valve one end is communicated with described secondary pipe network water circulating pump, the described three-way control valve other end is communicated with described heat exchanger, and described three-way control valve the 3rd end is communicated with the secondary net side outlet pipe of described heat exchanger; Described control device comprises temperature inductor and adjustment control, on described secondary net side return pipe and described secondary net side outlet pipe, be respectively equipped with described temperature inductor, described temperature inductor is connected with described adjustment control, described adjustment control is connected with described control valve, controls the water flow proportioning of described three-way control valve.
Described control valve comprises that secondary net side return pipe control valve is connected valve with secondary net side; On the described secondary net side return pipe between described secondary pipe network water circulating pump and the described heat exchanger, be provided with described secondary net side return pipe control valve; Described secondary net side connects valve one end and is communicated with described secondary net side return pipe between described secondary pipe network water circulating pump and the described secondary net side return pipe control valve; Described secondary net side connects the valve other end and is communicated with described secondary net side outlet pipe; Described adjustment control is connected valve with described secondary net side return pipe control valve respectively and connects with described secondary net side, control described secondary net side return pipe control valve is connected valve with described secondary net side water flow proportioning respectively.Advantage of the present utility model: overcome the defective that the hydraulic regime of net or secondary net was regulated or influenced once in existing heat exchange station heat supply, one germplasm regulating system is provided, regulate the secondary net and only change heat supply temperature, do not change water supply flow, can not cause user's appearance phenomenon uneven in temperature because of regulating secondary net heat supply temperature; Regulating neither influences once net hydraulic regime, does not destroy hydraulically balanced regulating system, and the hydraulically balanced adjusting of a webmaster net system is become simply, does not also change the hydraulic regime of secondary net.

Fig. 1 is the connection diagram of embodiment 1.
Fig. 2 is the connection diagram of embodiment 1.
The specific embodiment:
Embodiment 1: as shown in Figure 1, a kind of heat supply network heat exchange station secondary net matter regulating system, it comprises heat exchanger 1, secondary pipe network water circulating pump 2, on the secondary net side return pipe 3 of heat exchanger 2, be provided with secondary pipe network water circulating pump 2, it also comprises secondary net regulating system 4, secondary net regulating system 4 comprises control valve 5 and control device 6, control valve 5 is a three-way control valve 10, on the secondary net side return pipe 3 between secondary pipe network water circulating pump 2 and the heat exchanger 1, be provided with three-way control valve 10, three-way control valve 10 1 ends are communicated with secondary pipe network water circulating pump 2, three-way control valve 10 other ends are communicated with heat exchanger 1, and three-way control valve 10 the 3rd end is connected with secondary net side outlet pipe 7; Three control device 6 comprise temperature inductor 8 and adjustment control 9, on secondary net side return pipe 3 and secondary net side outlet pipe 7, be respectively equipped with temperature inductor 8, temperature inductor 8 is connected with adjustment control 9, adjustment control 9 is connected with three-way control valve 10, the water flow proportioning of control three-way control valve 10.
Embodiment 2: the heat supply network heat exchange station secondary net matter regulating system that a kind of and embodiment 1 are identical, and its difference is that as shown in Figure 2, control valve 5 comprises that secondary net side return pipe control valve 11 is connected valve 12 with secondary net side; On the secondary net side return pipe 3 between secondary pipe network water circulating pump 2 and the heat exchanger 1, be provided with secondary net side return pipe control valve 11; Secondary net side connects valve 12 1 ends and is communicated with secondary net side return pipe 3 between secondary pipe network water circulating pump 2 and the secondary net side return pipe control valve 11; Secondary net side connects valve 12 other ends and is communicated with secondary net side outlet pipe 7; Adjustment control 9 is connected valve 12 with secondary net side return pipe control valve 11 respectively and connects with secondary net side, control secondary net side return pipe control valve 11 is connected valve 12 with secondary net side water flow proportioning respectively.
Operation principle:
As shown in Figure 1 and Figure 2, on the secondary net side return pipe 3 between secondary pipe network water circulating pump 2 and the heat exchanger 1, be provided with control valve 5, backwater behind control valve 5 is divided into two-way, one tunnel interchanger 1 heating of reducing phlegm and internal heat, the secondary net side outlet pipe 7 of heat exchanger 1 is directly linked on another road without heat exchanger 1; Make the water supply of secondary net form through the hot water and the one tunnel direct Returning water of over-heat-exchanger 1 heating, and Total Water does not change by one the tunnel; Only be by control valve 12, changed two-way hot water or cold water's proportioning, thereby reached the purpose that changes secondary net supply water temperature.
For example, when reasons such as outdoor temperature are low, when needing to improve secondary net supply water temperature, by control valve 12 control water outlet proportionings, strengthen the water yield through over-heat-exchanger 1 one tunnel, also reduced cold circling water flow rate simultaneously, thereby improved the supply water temperature of secondary net, and total water supply flow does not change.
Therefore it is the matter regulative mode that a kind of alternating temperature degree does not change flow, to the not influence of hydraulic regime of secondary net, is to occur in secondary net side because regulate, and the once net of heat exchanger 1 does not participate in regulating, therefore to the once not influence of hydraulic regime of net.The confession that heat exchanger 1 is once netted (or returning) water comes the once hydraulic regime of net system of balance by the control valve of once netting.In case regulate, can be motionless.
