Description

Technical Field

[0001] The utility model relates to the technical field of the water circuit of a wall-mounted boiler, and more specifically, to a valve body heat insulation mechanism. Background Art

[0002] The domestic hot water (domestic water for bathing, washing vegetables, etc.) in the water circuit of a wall-mounted boiler is obtained by heat exchange between hot water and tap water through a heat exchanger, so that the temperature of the tap water rises. The tap water with the increased temperature is domestic hot water, which finally flows out from the terminal (such as a faucet, a shower head, etc.);

[0003] At present, most of the water circuits of wall-mounted boilers are designed in a modular manner. A valve body contains multiple water circuits. However, the water flowing in different water circuits may have different temperatures. In order to reduce the influence between water circuits with different temperatures in the valve body, a mechanism for heat insulation of the water circuit in the valve body is designed. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a valve body heat insulation mechanism. By setting a heat insulation pipe, the influence of the water temperature in the water passing channel on the water temperature of the water outlet at the domestic hot water outlet can be effectively reduced, and the accuracy of the water temperature of the water outlet at the domestic hot water outlet is effectively guaranteed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model discloses a valve body heat insulation mechanism, including a water outlet valve. The water outlet valve includes a domestic plate heat exchanger outlet, a first connection port, a second connection port, and a domestic hot water outlet. The domestic plate heat exchanger outlet is communicated with the first connection port, the second connection port is communicated with the domestic hot water outlet. There is a water passing channel inside the water inlet valve. The water passing channel is respectively communicated with the domestic plate heat exchanger outlet and the first connection port, and the water passing channel is blocked from the domestic hot water outlet. A heat insulation pipe is installed in the water passing channel, and the side wall of the heat insulation pipe is in sealing cooperation with the side wall of the water passing channel.

[0007] Further, the heat insulation pipe is located on the side of the domestic hot water outlet and the second connection port.

[0008] Further, the heat insulation pipe is made of plastic material.

[0009] Further, first annular grooves are provided at both ends of the side of the heat insulation pipe. Sealing rings are sleeved in the first annular grooves, and the side wall of the heat insulation pipe and the inner wall of the water passing channel are sealed through the sealing rings.

[0010] Further, a second annular groove is provided on the side of the heat insulation pipe. The second annular groove faces the domestic hot water outlet and the second connection port, and a closed cavity can be formed between the second annular groove and the water passing channel.

[0011] The beneficial effects of the present utility model are as follows:

[0012] During normal bathroom water discharge, since the water passage is close to the outlet of the bathroom plate heat exchanger, the water temperature in this flow channel is relatively high; the water flowing through the second connecting pipe and the bathroom hot water outlet is cooled after bypass servo mixing, so the water temperature in this flow channel is lower than that in the water passage. Therefore, by setting the heat insulation pipe, the influence of the water temperature in the water passage on the water temperature of the water discharged from the bathroom hot water outlet can be effectively reduced, and the accuracy of the water temperature of the water discharged from the bathroom hot water outlet is effectively guaranteed.

Detailed Embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 3 and Figure 4 shown, a valve body heat insulation mechanism includes a water outlet valve 2. The water outlet valve 2 includes a sanitary plate heat exchanger outlet 25, a first connection port 26, a second connection port 27, and a sanitary hot water outlet 28. The sanitary plate heat exchanger outlet 25 is communicated with the first connection port 26. The second connection port 27 is communicated with the sanitary hot water outlet 28. A water passing channel 29 is arranged inside the water outlet valve 2. The water passing channel 29 is respectively communicated with the sanitary plate heat exchanger outlet 25 and the first connection port 26. The water passing channel 29 is blocked from the sanitary hot water outlet 28. By arranging the water passing channel 29, it can effectively prevent the water coming out of the sanitary plate heat exchanger outlet 25 from directly flowing out of the sanitary hot water outlet 28.

[0024] An insulating pipe 9 is installed in the water passing channel 29. The side wall of the insulating pipe 9 is in sealing cooperation with the side wall of the water passing channel 29. The insulating pipe 9 is located above the sanitary hot water outlet 28 and on the side of the second connection port 27. The insulating pipe 9 is made of plastic material, and the heat conduction effect of the plastic insulating pipe 9 is poor. During normal sanitary water outlet, since the water passing channel 29 is close to the sanitary plate heat exchanger outlet 25, the water temperature in this flow channel is relatively high; the water flowing through the second connecting pipe 6 and the sanitary hot water outlet 28 is mixed with water by the bypass servo 3 and the temperature is reduced, so the water temperature in this flow channel is lower than the water temperature in the water passing channel 29. Therefore, by arranging the insulating pipe 9, it can effectively reduce the influence of the water temperature in the water passing channel 29 on the water temperature of the water outlet at the sanitary hot water outlet 28, and effectively ensure the accuracy of the water temperature of the water outlet at the sanitary hot water outlet 28.

[0025] Wherein, first annular grooves 91 are arranged at both ends of the side of the insulating pipe 9, and sealing rings 300 are sleeved in the first annular grooves 91. The side wall of the insulating pipe 9 is sealed with the inner wall of the water passing channel 29 through the sealing rings 300.

[0026] A second annular groove 92 is arranged on the side of the insulating pipe 9. The second annular groove 92 is opposite to the sanitary hot water outlet 26 and the second connection port 27. The second annular groove 92 and the water passing channel 29 can form a sealed cavity. By arranging the second annular groove 92, it can further reduce the influence of the water temperature in the water passing channel 29 on the water temperature of the water outlet at the sanitary hot water outlet 28.

[0027] A valve body heat insulation mechanism for a multi-servo water circuit module, and the multi-servo water circuit module includes a water inlet valve 1, a bypass servo 3 and a main servo 4;

[0028] The water inlet valve 1 includes a domestic water inlet 11, a sanitary plate heat exchanger inlet 12, a heating plate heat exchanger outlet 14 and a water pump interface 15. The domestic water inlet 11 is communicated with the heating plate heat exchanger outlet 14, and the water pump interface 15 is communicated with the heating plate heat exchanger outlet 14. The water pump interface 15 can be connected to an external water pump (not shown in the figure);

[0029] As Figure 1 And Figure 5 Shown, the water inlet valve 1 further includes a water replenishing port 13. The water replenishing port 13 is communicated with the domestic water inlet 11. After the external tap water enters the water inlet valve 1 from the domestic water inlet 11, it can enter the sanitary plate heat exchanger inlet 12 and the water replenishing port 13 respectively.

[0030] As Figure 1 And Figure 2 Shown, the water outlet valve 2 includes a three-way servo 21, a heating hot water inlet 22, a heating hot water outlet 23, a heating plate heat exchanger inlet 24, a sanitary plate heat exchanger outlet 25 and a sanitary hot water outlet 28. The hot water enters the water outlet valve 2 from the heating hot water inlet 22. Through the three-way servo 21, the heating hot water inlet 22 is communicated with the heating hot water outlet 23 or the heating plate heat exchanger inlet 24. When the heating hot water inlet 22 is communicated with the heating hot water outlet 23, it can supply heat for the floor heating (not shown in the figure). When the heating hot water inlet 22 is communicated with the heating plate heat exchanger inlet 24, the hot water can enter the heat exchanger 100 to exchange heat with the tap water. The three-way servo 21 is a prior art, and the way of making the heating hot water inlet 22 communicate with the heating hot water outlet 23 or the heating plate heat exchanger inlet 24 through the three-way servo 21 is also a prior art. Therefore, its specific structure and working principle are not described in detail in this specification.

[0031] As Figure 8 Shown, the sanitary plate heat exchanger inlet 12 is communicated with the sanitary plate heat exchanger outlet 25, and the heating plate heat exchanger inlet 24 is communicated with the heating plate heat exchanger outlet 14. Specifically, the sanitary plate heat exchanger inlet 12, the sanitary plate heat exchanger outlet 25, the heating plate heat exchanger inlet 24 and the heating plate heat exchanger outlet 14 can all be connected to the heat exchanger 100. The normal temperature tap water enters the heat exchanger 100 from the sanitary plate heat exchanger inlet 12, and the hot water also enters the heat exchanger 100 from the heating plate heat exchanger inlet 24. The normal temperature tap water and the hot water exchange heat in the heat exchanger 100. The heated tap water flows out of the heat exchanger 100 from the sanitary plate heat exchanger outlet 25, and the cooled hot water flows out of the heat exchanger 100 from the heating plate heat exchanger outlet 14. The hot water coming out of the heating plate heat exchanger outlet 14 finally discharges from the water pump interface 15;

[0032] The hot water flowing out from the water pump interface 15 is transported by the water pump to a boiler (not shown in the figure) for heating. After the heated and temperature - raised hot water flows out of the boiler, it enters the outlet valve 2 from the heating hot water inlet 22, realizing continuous heat exchange of normal - temperature tap water.

[0033] As Figure 1 , Figure 2 and Figure 8 shown, the outlet valve 2 further includes a first connection port 26 and a second connection port 27. The bypass servo 3 is respectively connected to the water replenishing port 13, the first connection port 26 and the main servo 4, and the main servo 4 is connected to the second connection port 27;

[0034] Specifically, the outlet valve 2 is connected to the bypass servo 3 through a first connecting pipe 5, the main servo 4 is connected to the outlet valve 2 through a second connecting pipe 6. The bypass servo 3 includes a third connection port 31, a fourth connection port 32 and a fifth connection port 33. The main servo 4 includes a sixth connection port 41. The first connecting pipe 5 includes an eighth connection port 51 and a ninth connection port 52. The water replenishing port 13 is connected to the third connection port 31, the fifth connection port 33 is connected to the sixth connection port 41, the eighth connection port 51 is connected to the first connection port 26, the ninth connection port 52 is connected to the fourth connection port 32. The main servo 4 further includes a seventh connection port 42, and both ends of the second connecting pipe 6 are respectively connected to the second connection port 27 and the seventh connection port 42;

[0035] The bathroom plate - heat exchanger outlet 25, the first connection port 26, the first connecting pipe 5, the bypass servo 3, the main servo 4, the second connecting pipe 6, the second connection port 27 and the bathroom hot water outlet 28 form a bathroom hot water outlet water path. The domestic water inlet 11, the water replenishing port 13 and the bypass servo 3 form a bathroom hot water cooling water path. The bathroom hot water cooling water path mixes with the bathroom hot water outlet water path inside the bypass servo 3 to form a mixing water path to reduce the water temperature of the bathroom hot water outlet water path. That is, in the bathroom hot water outlet water path, the water paths of the main servo 4, the second connecting pipe 6, the second connection port 27 and the bathroom hot water outlet 28 are mixing water paths mixed with normal - temperature tap water. Therefore, the water passing channel 29 is close to the bathroom plate - heat exchanger outlet 25, and the water temperature in this water passing channel 29 is relatively high; the water flowing through the second connecting pipe 6 and the bathroom hot water outlet 28 is cooled after mixing through the bypass servo 3, so the water temperature in this flow channel is lower than the water temperature in the water passing channel 29.

[0036] As Figure 1 and Figure 8As shown, a first temperature sensor 7 is installed on the side of the first connecting pipe 5, and the end of the first temperature sensor 7 is inserted into the first connecting pipe 5. A second temperature sensor 8 is installed on the side of the second connecting pipe 6, and the second temperature sensor 8 is inserted into the second connecting pipe 6. A third temperature sensor 200 is installed inside the water inlet valve 1, and the sensing part of the third temperature sensor 200 is located in the water replenishing port 13 to detect the water temperature at the water replenishing port 13. By providing the first temperature sensor 7, the water temperature before the tap water after heat exchange enters the bypass servo 3 can be detected. By providing the second temperature sensor 8, the water temperature before entering the second connection port 27 after mixing water in the bypass servo 3 can be detected. By providing the third temperature sensor 200, the water temperature of the normal temperature tap water before entering the bypass servo 3 can be detected.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
