Description

Technical Field

[0001] The invention belongs to the technical field of valves, and in particular relates to an electric temperature control valve. Background Art

[0002] An electric thermostatic valve is an electrically driven temperature control valve. A typical application of flow control valves in temperature control applications (such as heating). Its basic principle is to control the outlet temperature of a heat exchanger, air conditioning unit, or other heating or cooling equipment, or the primary hot (cold) medium, by controlling the inlet flow. When the load changes, the flow is adjusted by varying the valve opening to eliminate the effects of load fluctuations and restore the temperature to the set value. Electric thermostatic valves use a motor as a driving element. The controller receives temperature signals or commands from the management system, drives the valve core, and changes the valve opening to regulate flow. In the heating sector, electric thermostatic valves are typically installed at household entrances to adjust the flow of hot water delivered to each household, thereby regulating heat distribution.

[0003] Existing electric temperature control valves generally include a valve body and an electric actuator, which uses an electric actuator to drive the valve core to deflect. However, with the development of integrated technology, in the current heating system, it is difficult to meet the needs of only balancing the hot water flow / heat entering the house. On the user side, multiple groups of heat exchange components (heat exchange plates or floor heating pipes) are usually arranged in different areas. For users, it is an obvious need to distribute heat to each area to achieve a temperature balance effect. However, in current technology, regional temperature control after entering the house usually requires manual adjustment of multiple valves, which is not only cumbersome and laborious to operate, but also difficult to adjust to the appropriate state. Of course, temperature balance is a dynamic process. It is impossible for users to adjust multiple valves frequently, and appropriate technical means need to be developed and designed. In summary, it is necessary to develop and design electric temperature control valves to solve the above-mentioned technical problems. Summary of the Invention

This effectively prevents particulate matter in the household water source from flowing into the subsequent heat exchange components in each user area. The external filter is easy to disassemble and assemble, so this electric temperature control valve is easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0023] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The electric temperature-controlled valve of the present invention includes a central valve body 19, with a left valve body 3 disposed on its left side and a right valve body 12 disposed on its right side. The central valve body 19, the left valve body 3, and the right valve body 12 can be fabricated from a single metal block, such as an aluminum alloy block. To facilitate installation and use of the electric temperature-controlled valve, mounting holes are provided at the lower end of the left valve body 3 and the upper end of the right valve body 12 (these two mounting holes are positioned diagonally opposite each other). The electric temperature-controlled valve is secured to the bracket using bolts located within these mounting holes.

[0024] A water inlet connection 4 is provided at the bottom front portion of the left valve body 3. An internal flow channel 22 is provided within the interior of the middle valve body 19. The water inlet connection 4 and the internal flow channel 22 are interconnected. An internal thread is provided on the inner wall of the water inlet connection 4. The end of the water supply pipe is connected to the water inlet connection 4. Water entering the interior through the water inlet connection 4 flows into the internal flow channel 22.

[0025] A pre-flow valve core 7 is installed within the main water inlet port 4, and a pre-drive motor 1 for driving the pre-flow valve core 7 is mounted on the left valve body 3. The pre-drive motor 1 drives the pre-flow valve core 7 to deflect, thereby adjusting the opening and thus the flow rate of the total water supply. In this embodiment, a left cleaning port 6 is provided on the bottom outer side of the left valve body 3, which is connected to the main water inlet port 4. A left blind plug 5 is installed on the left cleaning port 6. When necessary, the left blind plug 5 can be removed to clean the dirt inside.

[0026] Multiple sets of upper and lower interfaces 11 and 8 are provided at the front of the middle valve body 19, and multiple water outlet interfaces 21 are provided at the rear of the middle valve body 19. Each lower interface 8 is connected to the internal flow channel 22, and each upper interface 11 is connected to each water outlet interface 21. The water supply in the internal flow channel 22 flows out from each lower interface 8, then flows in from each upper interface 11, and finally flows out from each water outlet interface 21. Therefore, the water supply entering through the main water inlet interface 4 forms a multi-channel output, which is supplied to the heating components in multiple different areas of the user. The inner wall of each water outlet interface 21 is provided with an internal thread, and the end of the water pipe is connected to the water outlet interface 21.

[0027] A post-flow valve core 2 is installed inside each water outlet interface 21, and multiple flow drive motors 9 for driving the post-flow valve core 2 are installed on the top of the middle valve body 19. A post-stop valve core 15 is installed inside each lower interface 8, and multiple stop drive motors 20 for driving the post-stop valve core 15 are installed on the bottom of the middle valve body 19. The flow drive motor 9 drives the post-flow valve core 2 to deflect, thereby adjusting the opening and adjusting the flow of each output. The stop drive motor 20 drives the post-stop valve core 15 to deflect, and the post-stop valve core 15 is either in a fully open state or in a fully closed state. When in the fully closed state, the water supply of this route is cut off. The purpose of setting the post-stop valve core 15 driven by the stop drive motor 20 is to quickly close the output of this route when abnormal water use in various user areas occurs (such as an increase in flow due to leakage).

[0028] In this embodiment, an upper connecting seat 10 is provided between the flow drive motor 9 and the top of the middle valve body 19, and the upper connecting seat 10 is connected to the top of the middle valve body 19 by screws; a lower connecting seat 18 is provided between the cut-off drive motor 20 and the bottom of the middle valve body 19, and the lower connecting seat 18 is connected to the bottom of the middle valve body 19 by screws.

[0029] An external filter 13 is installed between each group of upper interfaces 11 and lower interfaces 8. The function of the external filter 13 is to continuously filter the water supply of each line, thereby improving the cleanliness of the water supply of each line by filtering out the particulate matter contained therein, reducing the burden on subsequent heat exchange components, and alleviating scaling problems.

[0030] The external filter 13 comprises a filter housing and a filter screen located within the housing. The upper and lower ends of the filter housing are bent to the same side and connected to the upper and lower interfaces 11 and 8, respectively, using locknuts. This allows for convenient assembly and disassembly of the external filter 13, allowing maintenance personnel to easily remove and assemble the external filter 13 during maintenance operations. By replacing the external filter 13 with a new one, the electric temperature control valve maintains its effective filtering capabilities.

[0031] In this embodiment, a right cleaning port 17 is provided on the outside of the bottom of the right valve body 12, communicating with the internal flow passage 22. A right blind plug 16 is mounted on the right cleaning port 17. When it is necessary to release the scale-laden water source within the internal flow passage 22, the right blind plug 16 is removed, allowing the scale-laden water to flow out. Regular removal of the right blind plug 16 helps keep the interior of the electric temperature control valve clean and prevents flow problems caused by scale clogging the internal flow passage 22.

[0032] In this embodiment, a sensor interface 14 that is connected to the internal flow channel 22 is provided at the middle front part of the right valve body 12, and a temperature sensor and / or a pressure sensor is installed on the sensor interface 14. By adding a temperature sensor and / or a pressure sensor to this electric temperature control valve, the operating condition can be detected by detecting the internal thermometer pressure.

[0033] In this embodiment, the front drive motor 1, each flow drive motor 9 and each cut-off drive motor 20 are provided with a connection terminal, and the control harness of the controller is provided with a connection terminal. The corresponding connection terminals are plug-connected, such as Figure 4 As shown in FIG, the wiring terminals for the front drive motor 1 are located at the top of the body, while the wiring terminals for each flow drive motor 9 and each cutoff drive motor 20 are located at the front of the body. After the electric temperature control valve is installed on site, the control wiring harness of the controller is electrically connected to the electric temperature control valve via plug-in connections between the wiring terminals. The control commands of the controller and the detection signals of the temperature sensor and / or pressure sensor are transmitted through the control wiring harness.
