Specifically, as shown in FIGS. 3-5, the housing includes a bottom plate 31, and the bottom of the outlet valve 26 is disposed on the bottom plate 31, or the bottom of the outlet valve 26 is disposed adjacent to the bottom plate 31, to reduce the vertical dimension of the housing. Meanwhile, since the first living water pipeline 281 is communicated with the second water outlet hole 263, the first living water pipeline 281 can be prevented from bending and extending out of the housing, and thus the structure of the first living water pipeline 281 can be simplified; alternatively, it is avoided to provide an escape space for the first living water duct 281 between the bottom of the outlet valve 26 and the bottom plate 31, so that not only the structure of the first living water duct 281 but also the reduction of the vertical dimension of the housing is facilitated.

In the first embodiment of the control valve body, optionally, the blocking piece 27 is clamped or screwed to the first outlet hole 262.

In the first embodiment of the control valve body, optionally, the first living water pipeline 281 is a connection pipe, and the connection pipe is clamped or screwed to the second water outlet hole 263.

In the first embodiment of the control valve body, it should be noted that, no matter "the liquid storage container 24 is communicated with the first outlet hole 262, the blocking piece 27 blocks the second outlet hole 263", or "the blocking piece 27 blocks the first outlet hole 262, and the liquid storage container 24 is communicated with the second outlet hole 263", the basic water path of the heating and water heating apparatus 100 is not changed greatly.

In the second embodiment of the control valve body, the outlet valve 26 has an outlet hole communicated with the liquid storage container 24 and an inlet hole 261 communicated with the second flow passage, and the outlet hole is communicated with the inlet hole 261; the water inlet 261 is disposed on a side surface of the outlet valve 26 adjacent to the three-way valve, and the water outlet is disposed on a side surface of the outlet valve 26 away from the three-way valve. Thus, the distribution of the first living water pipe 281 can be easily designed by utilizing the space above the outlet valve 26, and the structure of the first living water pipe 281 can be simplified to facilitate the distribution of the living water pipes in the housing.

In order to facilitate understanding of the technical solutions and effects of the first and second embodiments of the control valve body, fig. 6 shows a schematic structural diagram of the control valve body when the liquid storage container is not provided in the basic design of the present invention, as shown in fig. 6, the outlet valve/26 b is integrally provided at one side of the three-way valve, the outlet valve/26 b has a first outlet 262b, a second outlet 263b and an inlet 261b, and the second outlet 263b communicates the inlet 261b and the first outlet 262 b; the water inlet 261b is disposed on a side surface of the outlet valve/26 b adjacent to the three-way valve, the first water outlet is disposed at the bottom of the outlet valve/26 b, and the second water outlet 263b is disposed on a side surface of the outlet valve/26 b away from the three-way valve.

It can be understood that, as shown in fig. 6, when the liquid storage container is not provided, the first outlet hole 262b can be directly extended downwards through a living water pipeline to communicate with the living water outlet. However, when the liquid storage container is provided, if the first living water pipeline is further communicated with the first water outlet 262b, the first living water pipeline needs to be bent upwards to communicate the first water outlet 262b with the liquid storage container, and the first living water pipeline is complex in distribution; if the first living water pipeline is communicated with the second water outlet hole, the structure of the first living water pipeline can be simplified.

The technical solutions and effects of the first and second embodiments of the control valve body are analyzed from the manufacturing process of the control valve body as follows.

Specifically, the three-way valve and the water outlet valve are integrally cast.

It can be understood that, in the process of integrally casting the control valve body, in order to reduce the casting difficulty, the first outlet hole 262/262b, the second outlet hole 263/263b and the inlet hole 261/261b are not directly cast, but a mother valve body without the first outlet hole, the second outlet hole and the inlet hole is cast first, and then the first outlet hole 262/262b, the second outlet hole 263/263b and the inlet hole 261/261b are machined on the mother valve body through machining (or other machining methods). It should be noted that, during machining, since the first water outlet hole cannot be directly communicated with the water inlet hole, the second water outlet hole needs to be machined so as to communicate the first water outlet hole with the water inlet hole; in the heating water heating device without the liquid storage container, the control valve body needs to block the second water outlet hole when in use.

Specifically, in the basic design of the present invention, as shown in fig. 6, since no liquid storage container is provided, the outlet valve can be directly communicated with the domestic water outlet through the first water outlet hole 262 b; in order to prevent water leakage, the second outlet hole 263b may be blocked by a blocking member (for example, the blocking member is fastened or screwed to the second outlet hole to block the second outlet hole).

And the utility model discloses heating hot water system has add the stock solution container for the stability that improves the hydrothermal temperature of life that heating hot water system provided, and further, for simplifying life water pipeline and heating system, can communicate first life water pipeline and second apopore to the first apopore of shutoff.

It can be understood that the utility model does not change the structure of the control valve body, but the function of the first water outlet hole and the second water outlet hole of the water outlet valve is exchanged, so that the connecting water path of the water outlet valve and the liquid storage container is simplified, and the liquid storage container is added under the condition that the water path distribution of the heating water heating device is not changed greatly; in addition, the universality of the control valve bodies of the warm water device provided with the liquid storage container and the warm water device not provided with the liquid storage container can be realized; meanwhile, the mold of the control valve body is universal, and the manufacturing cost is reduced.

It should be noted that, in order to achieve the above effects, only the second water outlet and the water inlet are machined during machining, and at this time, the second water outlet is the water outlet, and the water outlet is arranged on the side surface of the water outlet valve far away from the three-way valve. Therefore, the structure of the control valve body is basically unchanged, the connecting water path between the water outlet valve and the liquid storage container is simplified, and the liquid storage container is additionally arranged under the condition of not greatly changing the water path distribution of the heating hot water device; meanwhile, the mold of the control valve body is universal, and the manufacturing cost is reduced.

Further, as shown in fig. 1, the heating system 10 further includes a heating circulation pump 14, and the heating circulation pump 14 is used for driving a liquid circulation flow in the heating system.

Alternatively, the heating circulation pump 14 is provided to the first heating line 181.

Further, as shown in fig. 1, the hot water system 20 further includes a domestic water circulating pump 22, and the domestic water circulating pump 22 is used for driving the domestic water in the hot water system 20 to flow.

Alternatively, as shown in fig. 1, the live water circulation pump 22 is provided in the third live water line 283.
