[0019] Secondly, the utility model is described in detail in conjunction with the schematic diagram, and when the utility model implementation is described in detail, for the convenience of description, the sectional view of the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of the utility model protection here. In addition, the three-dimensional spatial dimension of length, width and depth should be contained in actual production.

[0020] In order to make the purpose, technical scheme and advantage of the utility model more clear, the implementation of the utility model will be described in further detail below with reference to the drawings.

[0021] Figs. 1-3 The whole structure schematic diagram of a novel active intervention type temperature control valve of the utility model is shown, please refer to Figs. 1-3 The novel active intervention type temperature control valve of the embodiment includes the shell 100, the water delivery main pipe 200 is arranged in the upper portion of the shell 100, the input end of the water delivery main pipe 200 is communicated with the water supply pipe and the output end is communicated with the cold water pipe input end of the water heater, the input end of the water delivery main pipe 200 is provided with the temperature sensor 300, the output end of the water delivery main pipe 200 is provided with the flowmeter 400, the water storage box 500 is arranged in the interior of the shell 100 and below the water delivery main pipe 200, the water inlet assembly 700 is connected between the top of the water storage box 500 and the water delivery main pipe 200, the water uniform sleeve 800 is arranged on the water delivery main pipe 200 and is close to the output end direction of the flowmeter 400, and the water delivery assembly 600 is connected between the water uniform sleeve 800 and the water storage box 500.

[0022] The water delivery assembly 600 includes a water guide pipe 610 having one end connected to the lower part of the inner cavity of the water storage box 500 and the other end connected to the water uniforming sleeve 800, a small liquid pump 620 arranged on the water guide pipe 610, and a check valve 630 arranged at the joint of the water guide pipe 610 and the water uniforming sleeve 800. The check valve 630 prevents the water in the water delivery main pipe 200 from flowing back to the water guide pipe 610 when the water delivery main pipe 200 normally delivers water. The water inlet assembly 700 includes a water guide pipe 710 having one end connected to the water delivery main pipe 200 and the lower end connected to the top of the inner cavity of the water storage box 500, and an electromagnetic flow valve 720 arranged at the joint of the water guide pipe 710 and the water delivery main pipe 200. The water storage box 500 is further provided with a liquid level meter. After some water is delivered, the water storage box 500 needs to be replenished with some water. When the water pressure and unit flow rate in the water delivery main pipe 200 return to the stable state, the electromagnetic flow valve 720 is immediately opened. The opening diameter is small to avoid affecting the water delivery of the water delivery main pipe 200. After opening, a continuous fine flow passes through the water guide pipe 710 into the water storage box 500. When the liquid level meter shows that the water storage amount in the box reaches the set value, the electromagnetic flow valve 720 is immediately closed, thereby ensuring normal intervention next time. Specifically, in the embodiment, when the water pressure suddenly decreases during use, the flow meter 400 immediately measures the unit delivery amount of the water delivery main pipe 200. At the same time, the water guide pipe 610 cooperates with the small liquid pump 620 to timely pump the standby water in the water storage box 500 to the water delivery main pipe 200, thereby filling the lost unit flow amount in the main pipe. After several seconds, when the flow measured by the flow meter 400 remains stable, the liquid pump gradually reduces the pumping amount and is closed. At the same time, the burner flame output is also gradually reduced and matched with the low water pressure to work under the cooperation of the control system. In this way, the water temperature output by the water heater can be effectively ensured to be in a lower temperature jump / temperature difference range, preventing the water temperature from suddenly rising to bring inconvenience to users, and improving the use experience of the temperature control valve.

[0023] Further, as a preferred, the two ends of the water uniforming sleeve 800 are fixedly connected to the end parts of the water delivery main pipe 200, the water uniforming sleeve 800 has a central flow channel 810 passing through the two water delivery main pipes 200 in the middle of the inner part, the inner part of the water uniforming sleeve 800 has a ring-shaped water collecting cavity 820, and a plurality of water outlet holes 830 are arranged on the ring-shaped partition plate between the ring-shaped water collecting cavity 820 and the central flow channel 810. On the basis of the above embodiment, in order to make the water delivered by the water guide pipe 610 into the water delivery main pipe 200 more linear and stable, the water output by the water guide pipe 610 first enters the ring-shaped water collecting cavity 820. Under the action of water pressure, the water accumulated in the ring-shaped water collecting cavity 820 is uniformly and dispersedly delivered to the water delivery main pipe 200 through the water outlet holes 830, thereby ensuring the linear output of water flow and being beneficial to the accurate measurement of the flow meter 400.

[0024] Further, the shell 100 has an access hole and an access cover 110 matched with the access hole on one side, and a junction box 900 is arranged outside the access cover 110.

[0025] Further, the water storage box 500 is provided with a water outlet and a cover 510 corresponding to the water outlet on one side of the bottom.

[0026] In summary, the new active intervention type temperature control valve in the embodiment can immediately measure the unit delivery amount of the water delivery main pipe 200 when the water pressure suddenly decreases during use, and at the same time, the water guide pipe 610 cooperates with the small liquid pump 620 to timely pump the standby water in the water storage box 500 to the water delivery main pipe 200, so as to make up for the unit water flow lost in the main pipe, and after several seconds (the specific time can be set according to the actual situation), when the flow measured by the flow meter 400 remains stable, the liquid pump gradually reduces the pumping amount and is closed, and at the same time, the burner flame output gradually reduces, and the low water pressure working is matched with the control system, so that the water temperature output by the water heater can be effectively ensured to be in a lower temperature jump / temperature difference range, and the sudden increase of the water temperature is prevented to bring inconvenience to the user.

[0027] Although the utility model has been described above with reference to the embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the features in the disclosed embodiments of the utility model can be combined in any way, and the combinations are not described in the specification due to the consideration of omitting the length and saving resources. Therefore, the utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
