Description

Technical Field

[0001] The utility model relates to the technical field of heating pipe networks, and in particular to a wireless double-valve joint control locking device for a heating system. Background Art

[0002] The central heating system has the advantages of on-demand heating, convenient management, high heat source efficiency, energy saving, and reduced carbon emissions. In actual operation, the central heating system often has disputes over whether the heating fee has been paid and the actual room temperature differences between different heat users. Therefore, the central heating system is equipped with a heating locking device and an adjusting device to cut off the heating users who have stopped heating or have not paid the heating fee and whose actual room temperature is higher than the set temperature, reduce the energy consumption of the heating system, and ensure the normal heating of the remaining heat users. The current heating locking device generally uses a manual ball valve or a locking valve, which is installed on the supply and return water pipeline and does not have a remote operation function; the heating regulating device generally installs an intelligent regulating valve on the return water pipeline, and adjusts the heating supply by adjusting the valve opening to achieve the purpose of on-demand heating. The intelligent regulating valve is often powered by an external power supply. In some scenarios where it is inconvenient or there is no on-site wiring or power supply, the installation of the existing heating locking device is relatively inconvenient. In the actual heating process, for users who have stopped heating or have not paid their bills, it is often necessary to manually close the supply and return water lock valves on site. This workload is large, automated management cannot be achieved, and the company's labor costs are high. Utility Model Content

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0018] like Figure 1 As shown, the utility model provides a wireless double-valve joint control locking device for a heating system, comprising a water supply pipeline 1, a return pipeline 2, a control console 4, an electric main valve 5, an electric auxiliary valve 6, and a room temperature collector 3 at a heat user end; the return pipeline 2 is provided with an electric main valve 5, and the electric main valves 5 at multiple heat user ends are wirelessly connected to the control console 4; the control console 4 simultaneously sends instructions to multiple heat user ends or receives data, forming a centralized control of the user end; the electric main valve 5 and the room temperature collector 7 can be connected by a wire, or by a wireless connection; the room temperature collector 7 is installed in the heat user's room, and the heat user can set the temperature through the room temperature collector 7, and the room temperature collector 7 obtains the actual room temperature in real time and transmits the data to the control console 4.

[0019] The water supply pipeline 1 is provided with an electric auxiliary valve 6, and the control end of the electric auxiliary valve 6 is connected to the electric main valve 5 through a wire. Specifically, the electric main valve 5 is an electrically adjustable lock valve; the electric auxiliary valve 6 is an electrically driven stop valve; the water supply pipeline 1 is also provided with a shut-off valve 7 and an inlet water temperature sensor; the return water pipeline 2 is also provided with a shut-off valve 7 and a return water temperature sensor. The electric main valve 5 is powered by a battery, and the electric auxiliary valve 6 is electrically connected to the electric main valve 5, that is, the actuator of the double valve does not need to rely on connecting to an external power supply. The electric main valve 5 and the electric auxiliary valve 6 are connected by a standard connector, and the electric auxiliary valve 6 is powered by the battery of the electric main valve 5, which saves on-site wiring work, reduces installation costs, and has strong adaptability.

[0020] When the control console 4 controls the electric main valve 5 to be in a fully open or throttling state, the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and is in a fully open state; when the control console 4 controls the electric main valve 5 to be in a fully closed state, the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and is in a fully closed state.

[0021] The electric main valve 5 is wirelessly connected to the control console 4 via a NB module or a 4G module. The use of the NB-IOT module can provide a low-power, low-cost, and high-reliability connection.

[0022] The locking execution process of the electric main valve 5 and the electric auxiliary valve 6 of the utility model is as follows:

[0023] S1. When the heating system adopts the room temperature control mode, the room temperature collector 3 uploads the actual room temperature and the set temperature of the heat user to the electric main valve 5, and the electric main valve 5 receives the valve state of the electric auxiliary valve 6. The electric main valve 5 wirelessly uploads the received data to the control console 4. The control console 4 automatically compares the difference between the actual room temperature and the set temperature, and transmits the corresponding control instructions to the electric main valve 5 to control the electric main valve 5 to be in an open state, a throttling state, or a closed state; the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and switches to an open or closed state. Specifically, when the actual room temperature is 0.5°C lower than the set temperature, the electric main valve 5 increases by one gear until it is fully open. During this process, the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and is in a fully open state; when the actual room temperature is 0.5°C higher than the set temperature, the electric main valve 5 is fully closed, and at the same time, the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and is in a fully closed state.

[0024] S2. When the heating system adopts the opening control mode, the electric main valve 5 obtains the control instruction of the control console 4, and drives the electric main valve 5 to reach the corresponding valve opening or fully closed. Specifically, when the electric main valve 5 receives the fully closed control instruction, the electric main valve 5 is fully closed, and the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and is in the fully closed state, realizing the user's fee control locking function; when the electric main valve 5 receives the valve opening instruction, it drives the electric main valve 5 to reach the corresponding valve opening; no matter what the opening of the electric main valve 5 is, the electric auxiliary valve 6 receives the control instruction of the electric main valve 5 and is fully opened.

[0025] It can be understood that the electric auxiliary valve 6 and the electric main valve 5 form a double-valve linkage locking device; when the user stops heating or fails to pay the heating fee, the double valves can remotely lock the supply and return water, realize automatic management, and reduce the labor cost of the enterprise. The double valves are managed according to one address, and the opening or closing of the electric auxiliary valve 6 only executes the switch command of the electric main valve 5, and does not need to execute other logics by itself, which reduces the cost of the electric auxiliary valve 6.

[0026] The above is a preferred embodiment of the present invention, and the description of the specific embodiment is only used to better understand the concept of the present invention. For ordinary technicians in this technical field, several improvements or equivalent substitutions can be made according to the principle of the present invention, and these improvements or equivalent substitutions are also considered to fall within the protection scope of the present invention.
