Description
Technical Field
[0001] The present technology relates to the field of antifreeze technology, and specifically is an antifreeze control device for user-segment pipelines and water meters. Background Art
[0002] With the increasing number of users, the intensification of extreme cold weather, the freezing of users' home tap water pipes (i.e. user section pipes) leading to water shortages, and the increasing phenomenon of water meter cracks have brought many inconveniences to people's lives and had serious negative impacts. At the same time, it has caused huge losses to water supply companies in terms of manpower and financial resources.
[0003] Different measures are taken for cold-proof and supply-guaranteeing work for pipe networks and equipment in different locations, for example, sand filling and grass paving are used for surface wells; wearing clothes and caps and covering films are used for exposed pipes and wall surfaces. Although this can solve a certain degree of freezing and cracking, once the temperature drops suddenly, the location is in a bad and humid environment in the shade, the wind speed is convective, and the insulation parts are damaged, and the water flow is stagnant at night, large areas of freezing of user-section pipes will still occur, resulting in no water and frozen water meters. The root cause of the problem is that the water in the pipes cannot be emptied in time.
[0004] Therefore, it is urgent to study a user section pipeline and water meter antifreeze control device to drain the water in the water meter and user section pipeline at a lower temperature in winter, thereby preventing the user section pipeline from freezing and water shortage and the water meter from freezing and cracking. Summary of the invention
[0005] The technical problem to be solved by the present technology is to provide a user section pipeline and water meter antifreeze control device in view of the deficiencies of the above-mentioned prior art. The user section pipeline and water meter antifreeze control device detects the ambient temperature in real time through the temperature sensing part of the temperature sensor controller, and then controls the electromagnetic three-way valve to switch the water flow direction through the automatic control part of the temperature sensor controller, thereby effectively controlling the water inlet and outlet of the user section pipeline, preventing the negative effects caused by the freezing of the user section pipeline and the explosion of the water meter, and at the same time, it can also enable users to use water at any time in this environment.
[0006] In order to achieve the above technical objectives, the technical solution adopted by this technology is:
[0007] A user section pipeline and water meter antifreeze control device mainly includes a temperature sensor controller, an electromagnetic three-way valve, and a ball suction and exhaust valve; one end of the user section pipeline is connected to the second interface of the electromagnetic three-way valve, the first interface of the electromagnetic three-way valve is connected to the municipal water supply network, the third interface of the electromagnetic three-way valve is connected to the rainwater well through a water pipe, the other end of the user section pipeline is connected to the water-using appliance, and the user section pipeline is provided with a ball suction and exhaust valve; the temperature sensor controller is connected to a power supply, and the automatic control part of the temperature sensor controller is connected to the electromagnetic three-way valve. The temperature sensing part of the temperature sensor controller is used to detect the ambient temperature around the water meter and send a signal to the automatic control part of the temperature sensor controller, and the automatic control part of the temperature sensor controller is used to receive the signal sent by the temperature sensing part and control the opening, closing, and exhausting actions of the electromagnetic three-way valve.
[0008] Furthermore, the electromagnetic three-way valve, the temperature sensing part of the temperature sensor controller and the water meter are all installed in the meter well.
[0009] Furthermore, a manual valve should be left on the user section pipeline.
[0010] Furthermore, the spherical suction and exhaust valve is located at a relatively high position of the user section pipeline close to the first water nozzle.
[0011] Furthermore, a start / stop button is additionally provided on the temperature sensor controller, and the temperature sensor controller is electrically connected to a power source via the start / stop button.
[0012] Furthermore, the temperature sensor controller is fixedly connected to a wall suitable for operation.
[0013] In the present technology, the temperature sensing part of the temperature sensor controller can be set near the water meter to detect the ambient temperature of the water meter in real time and send temperature information to the temperature sensor controller. The temperature sensor controller is provided with a display screen that can display the temperature. The temperature sensor controller determines whether the temperature reaches or is lower than the set value (for example, the freezing point temperature) according to the temperature sent by the temperature sensing part (i.e., the temperature sensing part). If it reaches or is lower than the set value, the automatic control part in the temperature sensor controller sends a control signal to the electromagnetic three-way valve. The initial state of the electromagnetic three-way valve is that the first interface is connected to the second interface. When the automatic control part in the temperature sensor controller sends a control signal to the electromagnetic three-way valve, the first interface of the electromagnetic three-way valve is disconnected from the second interface, and the second interface of the electromagnetic three-way valve is connected to the third interface. At this time, the water in the user section pipeline flows from the second interface of the electromagnetic three-way valve into the third interface, and flows into the rainwater well through the third interface and the water pipe. After the ambient temperature is lower than the set value, the automatic control part in the temperature sensor controller controls the electromagnetic three-way valve to switch the water flow direction, so that the water in the user section pipeline flows into the rainwater well through the electromagnetic three-way valve, and then the water in the user section pipeline and the water meter is emptied to prevent the water in the user section pipeline and the water meter from freezing. When the ambient temperature around the water meter reaches or is lower than the freezing point, when the user is in urgent need of water, he only needs to press the start-stop button on the temperature sensor controller to disconnect the temperature sensor controller from the power supply, and the automatic control part in the temperature sensor controller stops sending signals to the electromagnetic three-way valve, the electromagnetic three-way valve is powered off, and the electromagnetic three-way valve is reset to the initial state, that is, the second interface is disconnected from the third interface, and the first interface is connected to the second interface. The municipal water supply network flows to the water-using appliances (such as household faucets) through the electromagnetic three-way valve and the user section pipeline. Opening the household faucet can realize water use and realize smooth water supply for users. When there is no need to use water, press the start / stop button on the temperature sensor controller, the temperature sensor controller is connected to the power supply, and the temperature sensor controller starts to work. If the ambient temperature around the water meter is still at or below the freezing point, before the water in the user section pipeline freezes (it takes time for the water in the pipeline to freeze), the automatic control part in the temperature sensor controller can control the electromagnetic three-way valve to switch the water flow direction again, so that the water in the user section pipeline flows into the rainwater well, and the water in the user section pipeline and water meter is emptied to prevent the user section pipeline and water meter from freezing due to water accumulation. When the ambient temperature is above zero for a long time (such as spring, summer and autumn), you can press the start / stop button on the temperature sensor controller, or directly unplug the plug connecting the temperature sensor controller to the power supply to disconnect the temperature sensor controller from the power supply to avoid misoperation.
[0014] The beneficial effects of this technology are:
[0015] This technology is mainly used to solve the problems of freezing and waterlessness in user-segment pipelines and bursting of water meters due to freezing in winter when the temperature is low. This technology can effectively control the water inflow (i.e. providing water to users) and drainage (i.e. draining water to the rainwater well) of user-segment pipelines through temperature sensor controllers, ball-shaped air intake and exhaust valves, and electromagnetic three-way valves, to prevent the negative impacts of freezing caused by water in user-segment pipelines and bursting caused by freezing of water meters, so that users can use water smoothly. In addition, it can also reduce the immeasurable losses caused by freezing for water companies.
[0016] The spherical suction and exhaust valve in this technology has the functions of suction and exhaust, which solves the existence of atmospheric pressure, allows smooth water supply and drainage in the user section pipeline, and at the same time prevents damage to the user section pipeline caused by water hammer. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a structural schematic diagram of this embodiment. DETAILED DESCRIPTION
[0018] The specific implementation of the present technology is further described below according to the accompanying drawings:
[0019] A user section pipeline and water meter antifreeze control device, such as Figure 1 As shown, it includes a temperature sensor controller (including a temperature sensing part 6 for detecting temperature and an automatic control part 7 for controlling), an electromagnetic three-way valve 2, a water meter 3 and a user section pipeline 4.
[0020] One end of the user section pipeline 4 is connected to the second interface (B port) of the electromagnetic three-way valve 2, the first interface (A port) of the electromagnetic three-way valve 2 is connected to the municipal water supply network 1, the third interface (C port) of the electromagnetic three-way valve 2 is connected to the rainwater well 12 through a water pipe, and the other end of the user section pipeline 4 is connected to a water-using appliance, such as a household faucet 9. The user section pipeline 4 is installed with a water meter 3, a manual valve 5, and a ball-shaped air intake and exhaust valve 10. The automatic control part 7 of the temperature sensor controller is electrically connected to the electromagnetic three-way valve 2 to control the action of the electromagnetic three-way valve 2. The municipal water supply network 1 is generally buried, that is, it is below the antifreeze layer, and there is no need to consider the freezing problem.
[0021] The electromagnetic three-way valve 2 and the temperature sensing part 6 of the temperature sensor controller are both installed in the meter well, and are used to detect the ambient temperature of the water meter 3 in real time, and send temperature information to the automatic control part 7 of the temperature sensor controller. The temperature sensor controller is also provided with a display screen that can display the temperature. The automatic control part 7 of the temperature sensor controller determines whether the temperature reaches or is lower than the set value (for example, the freezing point temperature) according to the temperature detected by the temperature sensing part 6. If it reaches or is lower than the set value, the automatic control part 7 of the temperature sensor controller sends a control signal to the electromagnetic three-way valve 2. The initial state of the electromagnetic three-way valve 2 is that the first interface is connected to the second interface. When the automatic control part 7 of the temperature sensor controller sends a control signal to the electromagnetic three-way valve 2, the first interface of the electromagnetic three-way valve 2 is disconnected from the second interface, and the second interface of the electromagnetic three-way valve 2 is connected to the third interface. At this time, the water in the user section pipeline 4 flows from the second interface of the electromagnetic three-way valve 2 into the third interface, and flows into the rainwater well 12 through the third interface and the water pipe. After the ambient temperature is lower than the set value, the automatic control part 7 of the temperature sensor controller controls the electromagnetic three-way valve 2 to switch the water flow direction, so that the water in the user section pipeline 4 flows into the rainwater well 12, and then the water in the user section pipeline 4 is drained to prevent the user section pipeline 4 and the water meter 3 from freezing due to water accumulation.
[0022] In this embodiment, the electromagnetic three-way valve 2 , the temperature sensing part 6 of the temperature sensor controller, and the water meter 3 are all installed and arranged in the meter well 11 .
[0023] In this embodiment, the manual valve 5 is a control component in the pipeline fluid delivery system. It is used to change the passage cross-section and the flow direction of the medium and has the functions of diversion, cutoff, regulation, throttling, etc.
[0024] In this embodiment, the spherical air intake and exhaust valve 10 is located at a relatively high position near the first water nozzle end of the user segment pipeline 4. The spherical air intake and exhaust valve 10 has the functions of air intake and exhaust, and can quickly release and replenish the air in the user segment pipeline 4, ensure the required air pressure in the user segment pipeline 4, solve the existence of atmospheric pressure, make the user segment pipeline 4 water supply and drainage smooth, and prevent the user segment pipeline 4 from being damaged by water hammer.
[0025] In this embodiment, a start / stop button is additionally provided on the temperature sensor controller, and the temperature sensor controller is electrically connected to the power supply 8 via the start / stop button. The start / stop button can control the on / off between the temperature sensor controller and the power supply 8.
[0026] In this embodiment, the temperature sensor controller is fixedly connected to a wall suitable for operation.
[0027] Working principle: During normal water supply, the first interface of the electromagnetic three-way valve 2 is connected to the second interface, the manual valve 5 is in the open state, and the municipal water supply network 1 flows to the household faucet 9 through the electromagnetic three-way valve 2 and the user section pipeline 4. When the household faucet 9 is opened, water can be used. When the temperature sensing part 6 of the temperature sensor controller detects that the ambient temperature around the water meter 3 reaches or is lower than the freezing point, the automatic control part 7 of the temperature sensor controller sends a control signal to the electromagnetic three-way valve 2, the electromagnetic three-way valve 2 is energized, the first interface of the electromagnetic three-way valve 2 is disconnected from the second interface, and the second interface of the electromagnetic three-way valve 2 is connected to the third interface. Since the height of the rainwater well 12 is much lower than the height of the household faucet 9, that is, the rainwater well 12 is at a low place, at this time, the water in the user section pipeline 4 flows from the second interface of the electromagnetic three-way valve 2 to the third interface, and all flows into the rainwater well 12 through the third interface of the electromagnetic three-way valve 2 and the water pipe, and the water in the user section pipeline 4 and the water in the water meter 3 on the user section pipeline 4 are emptied; after the ambient temperature is lower than the freezing point, the electromagnetic three-way valve 2 switches the water flow direction, so that the water in the user section pipeline 4 flows into the rainwater well 12 through the electromagnetic three-way valve, and then the water in the user section pipeline 4 is emptied to prevent the water in the user section pipeline 4 and the water meter 3 from freezing. When the ambient temperature around the water meter 3 reaches or is lower than the freezing point, and the user is in urgent need of water, he only needs to press the start-stop button on the temperature sensor controller, the temperature sensor controller is disconnected from the power supply 8, the automatic control part 7 of the temperature sensor controller stops sending signals to the electromagnetic three-way valve 2, the electromagnetic three-way valve 2 is powered off, and the electromagnetic three-way valve 2 is reset to the initial state, that is, the second interface is disconnected from the third interface, the first interface is connected to the second interface, and the municipal water supply network 1 flows to the household faucet 9 through the electromagnetic three-way valve 2 and the user section pipeline 4. The household faucet 9 is opened to use water. When water is not needed, press the start-stop button on the temperature sensor controller, the temperature sensor controller is connected to the power supply 8, and the temperature sensor controller starts working. If the ambient temperature around the water meter 3 reaches or is lower than the freezing point, the automatic control part 7 of the temperature sensor controller can control the electromagnetic three-way valve 2 to switch the water flow direction again, so that the water in the user section pipeline 4 flows into the rainwater well 12. When the ambient temperature is above zero for a long time (such as in spring, summer and autumn), you can press the start / stop button on the temperature sensor controller, or directly unplug the plug connecting the temperature sensor controller to the power socket to disconnect the temperature sensor controller from the power supply 8 to avoid misoperation.
[0028] The temperature sensor controller, the electromagnetic three-way valve 2 and the spherical intake and exhaust valve 10 can use the existing commonly used models to achieve the above functions. The circuit inside the temperature sensor controller and the electromagnetic three-way valve 2 and the circuit connection relationship between the temperature sensor controller and the electromagnetic three-way valve 2 also use the existing technology. The internal structure and processing software of the temperature sensor controller also use the existing technology and are not within the protection scope of this technology.
[0029] The protection scope of the present technology includes but is not limited to the above embodiments. The protection scope of the present technology shall be based on the claims. Any replacement, deformation, and improvement of the present technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present technology.
