Description

Technical Field

[0001] The utility model provides a heating device, belonging to the technical field of water valve equipment, and particularly relates to a heating device for an integral electric-controlled water valve. Background Art

[0002] Electric water valves are water valves that are controlled using electricity and are usually used in automated systems or where remote control is required. They use electric actuators to open and close the valve and can be operated by external signals or controllers. Electric water valves are widely used in industries such as industry, construction and agriculture to improve efficiency and precision while reducing human intervention. These valves are usually programmable and can be controlled on a schedule or integrated with other systems as needed.

[0003] In a low-temperature environment, the water inside the current electric water valve may freeze, causing the valve core to be unable to move normally or the valve body to be damaged. In addition, in some application scenarios, the water valve needs to be used at a lower temperature, but the water valve may be affected at low temperatures and its working efficiency may be reduced. By heating the water valve, the working temperature of the water valve can be increased to ensure that it can still work efficiently in a low-temperature environment. However, the existing electric water valve heating module is complex to process and assemble, has a short lifespan and cannot guarantee the heating effect, and is prone to short circuits.

[0007] Preferably, the top of the thermostat is connected with an inlet and outlet line placed between the outer shell and the heating film, and the inlet and outlet line extends to the outside of the outer shell.

[0008] Preferably, the control range of the thermostat is between 30°C and 50°C. When the temperature is less than 30°C, the circuit is closed to start heating, and when the temperature is greater than 50°C, the circuit is disconnected to stop heating.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a heating device for an integrated electric-controlled water valve, comprising an outer shell 1, an inner lining 2 disposed inside the outer shell 1, a flame-retardant high-temperature outer coating 5 disposed outside the outer shell 1, a heating film 3 attached to the outside of the inner lining 2, and a thermostat 4 disposed outside the bottom end of the heating film 3 disposed inside the outer shell 1

[0022] In this embodiment, by providing a heating film 3 with a temperature controller 4, a range of the heating temperature of the heating film 3 can be limited. An inner lining 2 is provided inside the heating film 3 to provide support for the heating film 3 to prevent the heating film 3 from folding, short circuiting, etc. The heating film 3 can provide a better heating effect, and at the same time, the internal structure is simple and the installation is more convenient.

[0023] like Figure 2 and Figure 3 As shown, the top of the thermostat 4 is connected with an input and output line 6 placed between the outer shell 1 and the heating film 3, and the input and output line 6 extends to the outside of the outer shell 1. The control range of the thermostat 4 is between 30°C and 50°C. When the temperature is less than 30°C, the circuit is closed and heating starts. When the temperature is greater than 50°C, the circuit is disconnected and heating stops. The heating film 3 and the thermostat 4 and the input and output line 6 are electrically connected, and the input and output line 6 is externally connected to a power source.

[0024] In this embodiment, the utility model adopts a graphene heating film to increase the life of the heating device; a thermostat 4 is added to automatically turn on and off the heating according to the external temperature; an inner lining 2 (copper or stainless steel) is adopted to give the product a certain internal support, effectively preventing the internal folding of the heating film 3; a flame-retardant high-temperature outer coating film is used on the outside to prevent the occurrence of open flames; the thermostat 4 includes electronic components such as a power supply and a control unit, which are used to receive the temperature signal of the heating film and control the opening and closing of the internal circuit, thereby achieving precise control of the water valve temperature.

[0025] When in use, ensure that the electric water valve is installed in the required position and connected to the pipeline system. Check the outer shell, lining, heating film, thermostat and inlet and outlet wires of the heating device to ensure that they are intact; connect the inlet and outlet wires 6 to the external power supply to ensure that the power connection is normal and the heating device can be powered normally; adjust the control range of the thermostat 4 according to actual needs. Normally, the temperature is set between 30℃ and 50℃, which can be adjusted according to the ambient temperature and use requirements; when the temperature is lower than the set minimum temperature (30℃), the thermostat 4 automatically closes the circuit to start heating. The heating film 3 starts to work and provides heat to the water valve; the thermostat 4 will continuously monitor the temperature of the heating film 3 and control the heating according to the set temperature range. Once the temperature reaches the set maximum temperature (50℃), the thermostat 4 automatically disconnects the circuit to stop heating to avoid overheating; during the operation of the heating device, the electric water valve can operate normally, whether it is automatically or manually controlled. The heating device ensures that the water valve does not freeze in a low temperature environment, improving its working efficiency and reliability; regularly check whether the various components of the heating device are working properly, such as whether the heating film is damaged, whether the thermostat is accurate, etc. If there is any damage or abnormality, repair or replace it in time to ensure the normal operation of the heating device. Through the above steps, the heating device can be effectively used to heat the electric water valve, ensuring its normal operation under various environmental conditions and improving its performance and reliability.

[0026] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
