[0027] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example

[0030] The following is in conjunction with the appendix Figure 1 and 2 An example of a dual-valve control system for a heating pipeline will be described, such as... Figure 1 and 2 As shown,

[0031] The system includes a supply water pipeline 2 and a return water pipeline 1 connected to the heat user end. The return water pipeline 1 is equipped with an electric main valve 11, and the supply water pipeline 2 is equipped with an electric auxiliary valve 21. The electric main valve 11 is equipped with an actuator 12, and the electric auxiliary valve 21 is equipped with an actuator 22. Actuator 12 has a first interface 13 and a third interface 14, and actuator 22 has a second interface 23. The first interface 13 connects to a concentrator 5, which in turn connects to a control console. The third interface 14 is connected to the second interface 23 via a connecting wire 3. The first interface 13 and the third interface 14 connect to the controller inside actuator 12, and the second interface 23 connects to the controller inside actuator 22.

[0032] The electric auxiliary valve 21 is an electric shut-off valve with two states: fully open and fully closed. The electric main valve 11 is an electric adjustable shut-off valve. The electric main valve 11 can be opened to different degrees according to the user's specific needs to adjust the indoor temperature.

[0033] The console controls the opening size of the electric main valve 11 of each household through the concentrator 5, and then controls the electric auxiliary valve 21 through the electric main valve 11. Specifically, when the electric main valve 11 has an opening, the control module in the actuator one 12 sends a forward current to the actuator two 22 through the connecting wire 3, the electric auxiliary valve 21 receives the forward current, and the electric auxiliary valve 21 is fully opened. When the electric main valve 11 has no opening, the control module in the actuator one 12 sends a reverse current to the actuator two 22 through the connecting wire 3, the electric auxiliary valve 21 receives the reverse current, and the electric auxiliary valve 21 is fully closed. This can reduce the number of connections of the point of the concentrator 5 to each household, and increase the number of households controlled by each concentrator 5. The electric main valve 11 can be adjusted in opening, without affecting the adjustment of the room temperature of the user.

[0034] The wired control of the electric main valve 11 and the electric auxiliary valve 21 by the console can avoid the trouble of replacing the battery of the electric main valve 11 and the electric auxiliary valve 21 in wireless control.

[0035] As shown in the drawings, the connecting wire 3 is connected to the third interface 14 and the second interface 23 through the quick connector 4. The connecting wire 3 includes a power wire 31 and a control wire 32. The quick connector 4 includes an opening 411 on the shell 41 and a fixed sheet 42 in the shell 41. The fixed sheet 42 is provided with a movable pressing sheet 43 on one side. The fixed sheet 42 and the movable pressing sheet 43 are arranged at the opening 411. The shell 41 is further provided with a rotating rod 44. The rotating rod 44 is provided with a protrusion 45 corresponding to the movable pressing sheet 43.

[0036] The electric main valve 11, the electric auxiliary valve 21, the water supply pipeline 2 and the water return pipeline 1 are located in the same pipeline well. However, due to the installation of the on-site workers, the relative positions of the electric main valve 11 and the electric auxiliary valve 21 are not always fixed. The power wire 31 and the control wire 32 are general wires. A certain length of wire can be cut according to the specific relative positions of the electric main valve 11 and the electric auxiliary valve 21. The two ends of the wire are connected to the quick connector 4. The copper core of the wire is pressed between the fixed sheet 42 and the movable pressing sheet 43. The fixed sheet 42 is connected to the electric plug of the quick connector 4 inserted into the third interface 14 and the second interface 23. Thus, the electric main valve 11 and the electric auxiliary valve 21 are connected. The use is simple and the effect is good.

[0037] As shown in the drawings, the room temperature collector 6 is further provided at the hot user end, which is used for the operator to observe the temperature of the user end, so as to facilitate the adjustment of the water temperature.

[0038] In the description of the utility model, the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "vertical", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to describe the utility model and do not require the utility model to be necessarily constructed or operated in a particular orientation, and therefore should not be construed as limiting the utility model. In the utility model, "connected" and "connected" should be understood broadly, for example, it can be connected, or it can be detachably connected; it can be directly connected, or it can be indirectly connected through an intermediate component. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0039] The above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change or the like made according to the technical essence of the utility model to the above embodiments still falls within the protection scope of the utility model technical scheme.
