Description

Technical Field

[0001] This utility model relates to the field of mechanical process technology, and in particular to an automatic electric valve control water replenishment device for a centralized hot water supply system. Background Technology

[0002] In the operation of centralized hot water supply systems, fluctuations in user water usage and heat dissipation from pipes can easily lead to unstable system water levels. Traditional manual or mechanical water replenishment methods suffer from problems such as delayed response, insufficient accuracy, and high energy consumption, making it difficult to ensure stable and efficient system operation. This has created a demand for automatic electric valve-controlled water replenishment devices.

[0003] In existing technologies, when cold water is directly injected into the hot water tank during traditional water replenishment, the large temperature difference causes a sudden drop in local water temperature. Furthermore, the reliance on static valves makes it impossible to dynamically adjust the flow rate, leading to unstable water supply. This is mainly due to the lack of preheating treatment for water replenishment and a real-time dynamic flow control mechanism.

[0004] Therefore, an automatic electric valve control water replenishment device for a centralized hot water supply system is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic electric valve control water replenishment device for a centralized hot water supply system, which can solve the problems of sudden drop in water temperature caused by cold water dilution and unstable water supply caused by flow fluctuations.

[0008] Preferably, a linkage rod is fixedly connected to the top of the shield, and the linkage rod is slidably connected to both sides of the outside of the shield box.

[0009] Preferably, waterproof electronic telescopic rods are fixedly connected to the top of both sides of the shielding box, and lifting rods are fixedly connected to the top of the waterproof electronic telescopic rods. Lifting pull rods are rotatably connected to both sides of the lifting rods, and the two lifting pull rods are respectively rotatably connected to the opposite side of the two linkage rods.

[0010] Preferably, the adjusting assembly includes a first toothed plate, which is fixedly connected to the bottom of the top metering plate, and a second toothed plate is fixedly connected to the top of the bottom metering plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a quantitative heating mechanism, this application can achieve quantitative liquid replenishment through the quantitative heating structure of the lower water supply pipe, namely the adjustable volume temporary storage space formed by the outer electric heating sleeve and two sets of quantitative plates controlled by a waterproof servo motor and with adjustable spacing. By allowing cold water to enter the temporary storage space first, it is preheated according to the capacity before flowing into the hot water tank. This not only achieves quantitative liquid replenishment, but also avoids the problem of sudden drop in local water temperature caused by large temperature difference when cold water is directly injected into the hot water tank during traditional water replenishment. It achieves the effect of preheating and stabilizing water temperature.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] An automatic electric valve control water supply device for a centralized hot water supply system includes an upper water supply pipe 1, an electric valve body 2 fixedly connected to the bottom of the upper water supply pipe 1, a lower water supply pipe 3 fixedly connected to the bottom of the electric valve body 2, a quantitative heating mechanism 4 slidably connected to the inner side of the lower water supply pipe 3, and a flow control component 5 movably connected to the inner side of the quantitative heating mechanism 4. The quantitative heating mechanism 4 includes an electric heating sleeve 41, which is fixedly connected to the outer side of the lower water supply pipe 3. Sliding rails 42 are fixedly connected to both sides of the inner side of the lower water supply pipe 3. A quantitative plate 43 is slidably connected to the top and bottom of the inner side of the sliding rails 42. A water inlet 44 is opened on the inner side of the quantitative plate 43. An adjustment component 45 is movably connected to the opposite side of the two quantitative plates 43. The flow control component 5 is movably connected to the opposite side of the two quantitative plates 43.

[0026] In this embodiment: When the automatic electric valve body 2 is opened in the hot water supply system, cold water enters the hot water tank 7 through the lower water supply pipe 3. The lower water supply pipe 3 has an electric heating sleeve 41 on the outside and two sets of metering plates 43 on the inside. The lower water supply pipe 3 can be divided into three sections by adjusting the components 45 to move closer to or further away from the center of the lower water supply pipe 3. The opposite sides form a dynamic container with adjustable volume. The cold water is temporarily stored in the container. The electric heating sleeve 41 controls the heating temperature and time according to the capacity to achieve metered replenishment and preheating.

[0027] Specifically, such as Figure 5 As shown, the flow control component 5 includes two shielding boxes 51, and the two shielding boxes 51 are respectively fixedly connected to the opposite sides of the two metering plates 43. Both sides of the inner side of the shielding box 51 are slidably connected to shielding plates 52, and the shielding plates 52 are set on the outside of the water inlet 44.

[0028] Specifically, such as Figure 5 As shown, a linkage rod 53 is fixedly connected to the top of the shield 52, and the linkage rod 53 is slidably connected to both sides of the outer side of the shield box 51.

[0029] Specifically, such as Figure 5 As shown, waterproof electronic telescopic rods 54 are fixedly connected to the top of both sides of the shielding box 51. Lifting rods 55 are fixedly connected to the top of the waterproof electronic telescopic rods 54. Lifting rods 56 are rotatably connected to both sides of the lifting rods 55, and the two lifting rods 56 are rotatably connected to the opposite side of the two linkage rods 53 respectively.

[0030] In this embodiment: a flow rate adjustment structure consisting of two baffles 52 is provided on the outside of the metering plate 43. Specifically, a baffle box 51 is attached to the outer wall of the water inlet 44. The baffles 52 slide inside the baffle box 51. When the two baffles 52 are in contact, the baffle box 51 is solid and blocks the water inlet 44 to throttle the flow. When the opening needs to be increased, the waterproof electronic telescopic rod 54 on the outside of the baffle box 51 is activated, which moves the lifting rod 55 down. The lifting rods 56 distributed on both sides rotate outward, the opening becomes larger, and the baffles 52 are pushed to move to both sides to reduce the obstruction of the water inlet 44 and increase the opening, thereby adjusting the flow rate and velocity.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the adjustment assembly 45 includes a first toothed plate 4501, which is fixedly connected to the bottom of the top metering plate 43, and a second toothed plate 4502 is fixedly connected to the top of the bottom metering plate 43.

[0032] Specifically, such as Figure 3 , Figure 4As shown, a support box 4503 is fixedly connected to the inner side of the lower water supply pipe 3, and a waterproof servo motor 4504 is fixedly connected to the outer side of the support box 4503. A linkage gear 4505 is fixedly connected to the output end of the waterproof servo motor 4504. The linkage gear 4505 is located inside the support box 4503, and the linkage gear 4505 is meshed with the first toothed plate 4501 and the second toothed plate 4502 on opposite sides.

[0033] In this embodiment: by starting the waterproof servo motor 4504 on the outside of the support box 4503 at the center of the lower water supply pipe 3, the linkage gear 4505 located on the inner wall of the support box 4503 is driven to rotate. When the linkage gear 4505 rotates, the first toothed plate 4501 and the second toothed plate 4502, which mesh with it on both sides and are respectively connected to the two sets of metering plates 43, will move in opposite directions, so that the two metering plates 43 move closer to or away from the center of the lower water supply pipe 3 at the same time.

[0034] Specifically, such as Figure 1 As shown, a cold water pipe 6 is fixedly connected to the top of the upper water supply pipe 1.

[0035] Specifically, such as Figure 1 As shown, a hot water tank 7 is fixedly connected to the bottom of the lower water supply pipe 3.

[0036] In this embodiment: when replenishing water to the hot water tank 7 through the hot water supply system, cold water is transported by the upper cold water pipe 6 to the water replenishment system composed of the upper water replenishment pipe 1 and the lower water replenishment pipe 3 divided by the automatic electric valve body 2, and then flows into the hot water tank 7 to complete the water replenishment.

[0037] Working Principle: In the hot water supply system, the replenishment of hot water tank 7 is usually achieved by supplying cold water from the upper cold water pipe 6 to the replenishment system consisting of the upper replenishment pipe 1 and the lower replenishment pipe 3, which are divided by the automatic electric valve body 2, and then flowing into the hot water tank 7 to complete the replenishment. However, in this process, the direct entry of cold water into the hot water tank 7 will instantly dilute the hot water, causing a sudden drop in local water temperature, resulting in insufficient water temperature during the supply process. To avoid the above situation, when the automatic electric valve body 2 opens and cold water enters the hot water tank 7 through the lower replenishment pipe 3, a quantitative heating structure is provided on the outside and inside of the lower replenishment pipe 3. This mainly includes an electric heating sleeve 41 sleeved on the outside of the lower replenishment pipe 3, and a heating element located inside the lower replenishment pipe 3 that can be installed along the inner wall. The sliding rail 42 is composed of two sets of metering plates 43 that move closer to or further away from the center of the lower water supply pipe 3. These two sets of metering plates 43 divide the lower water supply pipe 3 into three sections, and the column formed by the opposite sides of the two metering plates 43 constitutes a dynamic container with adjustable volume. After cold water enters the container, it is temporarily stored, and the heating temperature and time are controlled according to the required capacity by the electric heating jacket 41 on the outside, so as to achieve the effect of metered liquid replenishment and preheating. The main way to achieve this is by starting the waterproof servo motor 4504 on the outside of the support box 4503 at the center of the lower water supply pipe 3, so that the linkage gear 4505 located at the output end of the waterproof servo motor 4504 rotates. The linkage gear 4505 is located on the support box 450. The inner wall of 3 is used to maintain support and limit its movement. When the linkage gear 4505 rotates, the first toothed plate 4501 and the second toothed plate 4502, which are connected to the two sets of metering plates 43 on both sides, will move in opposite directions. This achieves the effect of the two metering plates 43 moving closer to or further away from the center of the lower section water supply pipe 3, thereby achieving the purpose of metering and fulfilling the above requirements. Secondly, in order to regulate the flow rate and velocity of cold water entering the two metering plates 43, as well as the flow rate and velocity of hot water exiting the pipe, in addition to the original automatic electric valve body 2, a flow rate adjustment structure composed of double baffles 52 is provided on the outer side of the metering plates 43. The main distribution positions are as follows: a baffle box 51 is attached to the outer wall of the water inlet 44 of the metering plate 43, and the baffle 52 is attached to the outer wall of the water inlet 44. The device is slidably connected to the inner side of the shield box 51. When the two shield plates 52 are in contact, the shield box 51 is in a solid state, which blocks and seals the water inlet 44, thereby achieving the effect of throttling. When it is necessary to increase the opening to allow water inlet and outlet, the waterproof electronic telescopic rod 54 located on the outer extension of the shield box 51 is activated, causing the lifting rod 55 at the top of the waterproof electronic telescopic rod 54 to move downward. At this time, the two sets of lifting rods 56 arranged in a figure-eight pattern on both sides of the lifting rod 55 will rotate outward and increase the figure-eight opening. At the same time, the shield plates 52 are pushed to move to both sides to reduce the blocking area of ​​the water inlet 44 and increase the opening, thereby achieving the effect of regulating the flow rate and velocity. In summary, this realizes the innovation of the automatic electric valve control water replenishment device for the centralized hot water supply system.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
