[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the present invention proposes a mixed water direct supply heating system, comprising a water network pipe 1 connected to a heating company, through which the heating company outputs hot water. A user water pipe 2, which provides heat to the user, has its return end connected directly to the heating company. The hot water in the water network pipe 1 is diverted to the user water pipe 2 to provide heat to the user's home. Simultaneously, the heated water in the user water pipe 2 cools down and flows back to the heating company. As the water network pipe 1 delivers hot water, the hot water is inevitably hot and needs to be mixed with cooler water before being delivered to the user water pipe 2 to prevent burns caused by excessive heat.

[0034] Furthermore, the above-mentioned heating system also includes a water mixing mechanism 3 installed between the water network pipe 1 and the user water pipe 2. The water network pipe 1 and the user water pipe 2 are both connected to the water mixing mechanism 3. The water mixing mechanism 3 is used to mix the water in the water network pipe 1 and the user water pipe 2, reuse the heat of part of the water in the user water pipe 2, avoid using cold water to mix with hot water in the water network pipe 1 to cool it down, reuse the temperature of the water in the user water pipe 2, and reduce heat loss. The water mixing mechanism 3 includes a mixing tank 31. A first liquid inlet pipe 32 is fixedly installed on the top of the mixing tank 31. The first liquid inlet pipe 32 is connected to the water network pipe 1. A second liquid inlet pipe 33 is also installed on the top of the mixing tank 31. The second liquid inlet pipe 33 is connected to the user water pipe 2. A water outlet pipe 35 is provided on one side of the mixing tank 31. The water outlet pipe 35 is connected to the liquid inlet end of the user water pipe 2. The water outlet pipe 35 facilitates the delivery of the mixed water to the user water pipe 2. The mixing tank 31 is equipped with multiple sets of mesh panels 34. After water from the water supply network pipe 1 and the user water pipe 2 enters the mixing tank 31 through the first and second liquid inlet pipes 32 and 33, it is then evenly mixed through the holes in the multiple sets of mesh panels 34. A pressure gauge 7 is mounted on the inner wall of the mixing tank 31 to monitor the water pressure. A thermometer 8 is also mounted on the inner wall of the mixing tank 31 near the outlet pipe 35 to monitor the water temperature.

[0035] For further information, see Figure 3 and Figure 4 The above-mentioned heating system includes a regulating mechanism 4 installed in the mixing water tank 31. The regulating mechanism 4 is used to adjust the liquid inlet amount of the first liquid inlet pipe 32 and the second liquid inlet pipe 33. The regulating mechanism 4 includes two sets of symmetrically arranged fixing sleeves 41. Both sets of fixing sleeves 41 are U-shaped. The two sets of fixing sleeves 41 are respectively arranged on the side of the first liquid inlet pipe 32 and the second liquid inlet pipe 33 close to the mixing water tank 31. The two sets of fixing sleeves 41 are fixedly connected to the inner wall of the mixing water tank 31. The positions of the fixing sleeves 41 are fixed. The water flowing into the first liquid inlet pipe 32 and the second liquid inlet pipe 33 all pass through the fixed sleeves 41. Two sets of fixing plates 42 are fixedly connected on both sides of the two sets of fixing sleeves 41, and the positions of the fixing plates 42 are also fixed. Four sets of positioning plates 43 are fixedly connected between the two sets of fixing plates 42 on the same side. Two sets of limiting rods 44 are fixedly connected between the two sets of positioning plates 43. The positions of the limiting rods 44 on the positioning plates 43 are fixed. The two sets of limiting rods 44 are slidably connected to limiting sleeves 45, allowing the limiting sleeves 45 to move smoothly under the limiting action of the limiting rods 44. An adjustment block 46 is fixedly connected between the two sets of limiting sleeves 45, allowing the adjustment block 46 to move smoothly under the limiting action of the limiting rods 44 and limiting sleeves 45. The adjustment block 46 is slidably connected to the fixed sleeve 41. As it slides, the adjustment block 46 is used to adjust the flow rate in the fixed sleeve 41, thereby adjusting the amount of liquid inlet to the first and second liquid inlet pipes 32 and 33.

[0036] Specifically, the above-mentioned heating system includes a pressure regulating assembly 5 installed on the mixing water tank 31, and the pressure regulating assembly 5 is used to adjust the water pressure in the mixing water tank 31. The pressure regulating assembly 5 includes two groups of first limit bars 51 fixedly connected to the inner wall of the mixing water tank 31. The two groups of first limit bars 51 are symmetrically arranged. The first limit bars 51 are L-shaped structures. A mounting plate 52 is slidably connected between the two groups of first limit bars 51. The mounting plate 52 is made of rubber to improve the sealing performance. The first limit bar 51 and the mounting plate 52 are used to ensure that the position where the servo motor 53 slides will not leak. A servo motor 53 is installed on the outside of the mounting plate 52. The output end of the servo motor 53 passes through the first limit bar 51 and is fixedly connected to a rotating rod 54. After the servo motor 53 is started, it drives the rotating rod 54 to rotate. A gear 55 is fixedly connected to the rotating rod 54. When the rotating rod 54 rotates, the gear 55 rotates synchronously. A gear 55 is positioned between the two sets of adjustment blocks 46. A set of racks 56 is positioned above each gear 55. Both sets of racks 56 mesh with the gear 55, and when the gear 55 rotates, it drives the adjustment blocks 46 to move. The two sets of racks 56 are fixedly connected to the two sets of adjustment blocks 46, respectively. When the racks 56 move, they drive the adjustment blocks 46 to move synchronously. The adjustment blocks 46 are provided with corresponding clearance slots 57, which allow the racks 56 to make way when the two sets of adjustment blocks 46 approach, preventing the racks 56 from hitting the adjustment blocks 46 when the two sets of adjustment blocks 46 approach. Simultaneously, when the gear 55 rotates, the two sets of racks 56 move in opposite directions, causing the two sets of adjustment blocks 46 to move in opposite directions. This allows the water inflow into the first and second liquid inlet pipes 32 and 33 to be adjusted, thereby regulating the water pressure in the mixing tank 31.

[0037] Finally, the heating system further includes a thermostat assembly 6 disposed on the mixing tank 31. The thermostat assembly 6 is used to adjust the water temperature in the mixing tank 31. The thermostat assembly 6 includes two sets of movable plates 61 rotatably connected to the rotating rod 54. The two sets of movable plates 61 are respectively disposed on both sides of the adjustment block 46. Two sets of sliding bars 62 are fixedly connected to each side of the movable plates 61. The side of the sliding bar 62 away from the movable plates 61 is slidably connected to a second limiting bar 63. The second limiting bar 63 is an L-shaped structure. The arrangement of the sliding bar 62 and the second limiting bar 63 ensures smooth sliding of the movable plates 61. The second limiting bar 63 is fixedly connected to the side of the limiting sleeve 45 away from the adjustment block 46, and the second limiting bar 63 moves synchronously with the limiting sleeve 45. A mounting frame 64 is mounted on the side of one set of movable plates 61 away from the adjustment block 46. The rotating rod 54 is rotatably connected to the mounting frame 64, and the mounting frame 64 moves synchronously with the rotating rod 54 and the movable plates 61. A push rod motor 65 is installed on the outside of the mixing tank 31. The output end of the push rod motor 65 passes through the side wall of the mixing tank 31 and is fixedly connected to the mounting frame 64. The push rod motor 65 is used to drive the mounting frame 64 to move after startup, and at the same time drive the rotating rod 54 to move. When the gear 55 does not rotate, the two sets of adjustment blocks 46 can also move in the same direction, so that the water inlet amount of the first liquid inlet pipe 32 and the second liquid inlet pipe 33 can be adjusted according to the water temperature information monitored by the thermometer 8 to achieve the appropriate water temperature.

[0038] In this embodiment, hot water from the heating company enters the first liquid inlet pipe 32 through the water network pipe 1 and flows into the mixing tank 31. Simultaneously, warm water from the user's home in the user water pipe 2 enters the mixing tank 31 through the second liquid inlet pipe 33. The hot and warm water mix further as they pass through the holes in the mesh plate 34, resulting in a uniform water temperature in the mixing tank 31. Simultaneously, a pressure gauge 7 monitors the water pressure in the mixing tank 31. Due to varying ambient temperatures, the water in the water network pipe 1 can have varying temperatures upon reaching the mixing tank 31, resulting in varying water pressures. When the water pressure is low, the servo motor 53 is activated, driving the rotating rod 54, which in turn rotates the gear 55 and drives the two sets of racks 56 in opposite directions. The racks 56 drive the two sets of adjustment blocks 46 toward each other. The adjustment blocks 46 move smoothly under the restraining action of the limit rod 44 and the limit sleeve 45. The second limit bar 63 slides alongside the sliding bar 62 without affecting the position of the movable plate 61. This increases the amount of liquid flowing into the first and second liquid inlet pipes 32 and 33, thereby increasing the water pressure in the mixing tank 31. When the water pressure is high, the servo motor 53 is activated to rotate in the opposite direction, driving the two sets of regulating blocks 46 away from each other, thereby reducing the amount of liquid flowing into the first and second liquid inlet pipes 32 and 33, thereby reducing the water pressure in the mixing tank 31.

[0039] When the thermometer 8 senses that the water temperature in the mixing tank 31 is too low, the push rod motor 65 is activated, causing it to retract and simultaneously moving the mounting frame 64. Simultaneously, the rotating rod 54 also moves. Since the servo motor 53 is not activated at this time, the gear 55 does not rotate. Meanwhile, the movement of the rotating rod 54 drives the movable plate 61 and the adjustment block 46 to move synchronously, causing the two sets of adjustment blocks 46 to move synchronously toward the push rod motor 65. This increases the amount of liquid flowing into the first liquid inlet pipe 32 and decreases the amount of liquid flowing into the second liquid inlet pipe 33, thereby raising the water temperature in the mixing tank 31. When the water temperature in the mixing tank 31 is too high, the push rod motor 65 is activated to extend, causing the amount of liquid flowing into the first liquid inlet pipe 32 to decrease and the amount of liquid flowing into the second liquid inlet pipe 33 to increase, thereby raising the water temperature in the mixing tank 31.

[0040] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
