Description

Technical Field

[0001] This utility model relates to the field of heating pipe water supply technology, and in particular to a heating secondary network water supply device with energy-saving and resistance-reducing functions. Background Technology

[0002] The secondary heating network is a crucial component of the centralized heating system. It refers to the hot water pipe network from the heat exchange station in the heating community to the entrance of the user's building. In the heat exchange station of the secondary heating network, water from the primary network is exchanged with water from the secondary network, raising the temperature of the secondary network water before it is used by the residents. Because the water storage tank in the secondary heating network is filled with water to maintain the water pressure, the current water replenishment method mainly relies on staff to turn on the water pump to directly replenish the water. This method cannot achieve automatic water replenishment. Staff need to monitor the water pressure in the pipe network regularly and then replenish the water accordingly. This method has low automation and is labor-intensive and time-consuming. Secondly, the water temperature in the pipe network is relatively high. If hot water is directly added for replenishment, hot water needs to be kept on hand, which consumes a lot of energy. If cold water is added, adding a large amount of cold water in a short period of time will directly lower the water temperature in the heating pipe network.

[0003] In view of this, there is an urgent need for a heating secondary network water supply device with energy-saving and resistance-reducing functions to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a heating secondary network water supply device with energy-saving and resistance-reducing functions to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a heating secondary network water supply device with energy-saving and resistance-reducing functions, comprising:

[0006] The tank consists of a cover, an inlet pipe, an outlet pipe, a water supply pipe, and a water level control component. The cover is detachably connected to the top of the tank. The lower end of the water supply pipe penetrates the cover and is fixedly connected to it. The inlet pipe and outlet pipe are fixedly connected to the lower end of the curved side wall of the tank in symmetrical positions. The tank is equipped with a partition that divides it into a water supply chamber and a water storage chamber. A water supply hole is provided in the middle of the partition. The water level control component is movably connected to the water supply chamber.

[0007] Preferably, the water level control assembly includes a buoyancy block, an outer sleeve, an inner sleeve rod, a spring, a displacement plate, and a water seal plate. The outer sleeve is fixedly connected to the middle position of the buoyancy block, the displacement plate is slidably connected inside the outer sleeve, the lower end of the spring is fixedly connected to the bottom of the outer sleeve, and the upper end of the spring is fixedly connected to the bottom wall of the displacement plate. The inner sleeve rod penetrates the top wall of the outer sleeve and is fixedly connected to the displacement plate, and the inner sleeve rod is slidably connected to the outer sleeve. The water seal plate is fixedly connected to the upper end of the inner sleeve rod, and the water seal plate matches the water inlet hole.

[0008] Preferably, the buoyancy block is provided with at least one matching limiting rod, the lower end of the limiting rod is fixedly connected to the bottom wall of the water replenishment chamber, and the upper end passes through the buoyancy block and is fitted with it with a clearance.

[0009] Preferably, the buoyancy block is filled with a counterweight block that is fixedly connected to it.

[0010] Preferably, the cover body is provided with a water replenishment control component, which includes an elastic telescopic rod, a circular plate and a traction line. The circular plate penetrates the curved side wall of the water replenishment pipe and is fitted with it with a gap. One end of the elastic telescopic rod is fixedly connected to the curved side wall of the cover body, and the other end is fixedly connected to the circular plate. One end of the traction line is fixedly connected to the buoyancy block, and the other end passes through the side wall of the water replenishment pipe away from the elastic telescopic rod and is fixedly connected to the circular plate. The traction line is fitted with the water replenishment pipe with a gap.

[0011] Preferably, the diameter of the water supply pipe is greater than the maximum tensile length of the elastic telescopic rod.

[0012] Preferably, a blocking plate is provided at one end of the water supply pipe inside the tank. The blocking plate is hinged to the water supply pipe on one side, and an arc-shaped float is fixedly connected to the blocking plate on the side wall away from the water supply pipe.

[0013] Specifically, the water supply chamber has an outlet pipe and a filter screen installed at an angle on the lower end of one side wall. The filter screen has a sedimentation pipe and a collection tank that match its position. The upper end of the sedimentation pipe penetrates the bottom wall of the water supply chamber and is fixedly connected to it. Its lower end is threadedly connected to the collection tank.

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

[0015] 1. In this utility model, the tank is divided into a water storage chamber and a water replenishment chamber by a partition inside the tank. The water in the water replenishment chamber can automatically replenish the water missing in the water inlet pipe and then be discharged through the water outlet pipe. The advantage of this setting is that the water replenishment process is continuous, that is, the proportion of water replenished in the unit volume of circulating water is small, avoiding the situation of sudden drop in water temperature caused by replenishing a large amount of water in a short period of time.

This not only effectively utilizes the heat of the circulating water, but also avoids the problem of a large temperature difference between the external water used for water replenishment and the circulating water.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see the appendix Figure 1-3 A heating secondary network water supply device with energy-saving and resistance-reducing functions includes:

[0024] The tank consists of a tank body 1, a cover 2, an inlet pipe 3, an outlet pipe 4, a water replenishment pipe 5, and a water level control component 6. The cover 2 is detachably connected to the top of the tank body 1. The lower end of the water replenishment pipe 5 penetrates the cover 2 and is fixedly connected to it. The inlet pipe 3 and the outlet pipe 4 are symmetrically fixedly connected to the lower end of the curved side wall of the tank body 1. The tank body 1 is provided with a partition 12 that divides it into a water replenishment chamber 10 and a water storage chamber 11. A water replenishment hole 120 is provided in the middle of the partition 12. The water level control component 6 is movably connected to the water replenishment chamber 10.

[0025] Specifically, the water level control component 6 includes a buoyancy block 60, an outer sleeve 61, an inner sleeve rod 62, a spring 63, a displacement plate 64, and a water seal plate 65. The outer sleeve 61 is fixedly connected to the middle position of the buoyancy block 60. The displacement plate 64 is slidably connected inside the outer sleeve 61. The lower end of the spring 63 is fixedly connected to the bottom of the outer sleeve 61, and the upper end of the spring 63 is fixedly connected to the bottom wall of the displacement plate 64. The inner sleeve rod 62 penetrates the top wall of the outer sleeve 61 and is fixedly connected to the displacement plate 64. The inner sleeve rod 62 is slidably connected to the outer sleeve 61. The water seal plate 65 is fixedly connected to the upper end of the inner sleeve rod 62, and the water seal plate 65 matches the water inlet hole 120.

[0026] The tank 1 is divided into a water replenishment chamber 10 and a water storage chamber 11. Under normal conditions, the water seal plate 65 is located at the water replenishment hole 120 and blocks it. At this time, the spring 63 is in a compressed state. In this state, the heat dissipation of the circulating water in the water replenishment chamber 10 is conducted to the baffle plate 12, and the baffle plate 12 provides appropriate insulation for the water in the water storage chamber 11. When the circulating water in the inlet pipe 3 has insufficient pressure, the water in the water replenishment chamber 10 will automatically replenish the water when it enters the outlet pipe 4, without the need to constantly monitor the water pressure. When the water level in the water replenishment chamber 10 is lower than the first critical value, the buoyancy block... As the water level drops, the outer sleeve 61 drives the spring 63 to descend with the buoyancy block 60. The spring 63 gradually releases its elastic force. During this process, the position of the water seal plate 65 remains unchanged. When the water level in the water replenishment chamber 10 is lower than the second critical value, the elastic force of the spring 63 is completely released, and the water seal plate 65 loses contact with the water replenishment hole 120. The water in the water storage chamber 11, which is in a heat preservation state, begins to enter the water replenishment chamber 10 and gradually raises the water level in the water replenishment chamber 10 until it drives the buoyancy block 60 back to the position of the first critical value, and forces the water seal plate 65 to contact the water replenishment hole 120 again and seal it.

[0027] Specifically, the buoyancy block 60 is provided with at least one matching limiting rod 600. The lower end of the limiting rod 600 is fixedly connected to the bottom wall of the water replenishment chamber 10, and its upper end passes through the buoyancy block 60 and is fitted with it with a clearance. Considering that the water in the water replenishment chamber 10 is in a flowing state, if the limiting rod is not used, the buoyancy block 60 may change position, causing the water seal plate 65 to be misaligned with the water replenishment hole 120, which in turn causes the water level control component 6 to lose its proper function. Therefore, the limiting rod 600 is used to limit the position of the buoyancy block 60 so that it can only move in the vertical direction.

[0028] Specifically, the buoyancy block 60 is filled with a counterweight block 601 that is fixedly connected to it.

[0029] Specifically, the cover 2 is provided with a water replenishment control component 7, which includes an elastic telescopic rod 70, a circular plate 71, and a traction line 72. The circular plate 71 penetrates the curved side wall of the water replenishment pipe 5 and is in clearance fit with it. One end of the elastic telescopic rod 70 is fixedly connected to the curved side wall of the cover 2, and the other end is fixedly connected to the circular plate 71. One end of the traction line 72 is fixedly connected to the buoyancy block 60, and the other end passes through the side wall of the water replenishment pipe 5 away from the elastic telescopic rod 70 and is fixedly connected to the circular plate 71. The traction line 72 is in clearance fit with the water replenishment pipe 5.

[0030] Considering that when water in the water storage chamber 11 flows into the water replenishment chamber 10, water in the water replenishment pipe 5 may continue to flow into the water storage chamber 11, and the temperature of the newly added water may differ significantly from that of the circulating water, a water replenishment control component 7 is set up to avoid this situation. When the water seal plate 65 descends to the second critical value along with the buoyancy block 60, the water seal plate 65 will move the circular plate 71 through the traction line 72, blocking the water replenishment pipe 5. As water in the water storage chamber 11 enters the water replenishment chamber 10, when the buoyancy block 60 returns to the first critical value, the water seal plate 65 gradually loses its pulling force on the traction line. During this process, under the elastic force of the elastic telescopic rod 70, the circular plate 71 returns to its initial position, and the water replenishment pipe 5 replenishes water into the water storage chamber 11 again.

[0031] Specifically, the diameter of the water supply pipe 5 is greater than the maximum extension length of the elastic telescopic rod 70. Considering that if the circular plate 71 loses contact with the water supply pipe 5 during a single movement, it may be unable to re-enter the water supply pipe 5 without external force, the extension length of the elastic telescopic rod 70 is limited. That is to say, during the return process of the elastic telescopic rod 70, a part of the circular plate 71 is always inside the water supply pipe 5.

[0032] Specifically, the water supply pipe 5 is provided with a blocking plate 50 at one end inside the tank 1. The blocking plate 50 is hinged to the water supply pipe 5 on one side, and an arc-shaped float 500 is fixedly connected to the blocking plate 50 on the side wall away from the water supply pipe 5. Considering that the water supply pipe 5 may continuously supply too much water to the water storage chamber 11, a blocking plate 50 and an arc-shaped float 500 are provided at the lower end of the water supply pipe 5. When the water level in the water storage chamber 11 reaches a certain height, the arc-shaped float 500 will push the blocking plate 50 to block the lower end of the water supply pipe 5, thus avoiding the problem of excessive water supply to the water storage chamber 11.

[0033] Specifically, the water replenishment chamber 10 is provided with a filter screen 13 installed at an angle on the lower end of one side wall of the water outlet pipe 4. The filter screen 13 is provided with a sedimentation pipe 14 and a collection tank 15 that match its position. The upper end of the sedimentation pipe 14 penetrates the bottom wall of the water replenishment chamber 10 and is fixedly connected to it. Its lower end is threadedly connected to the collection tank 15. A butterfly valve 16 is provided in the middle of the sedimentation pipe 14.

[0034] Considering that scale and rust from metal pipes may mix into the circulating water during the circulation process, if not cleaned in time, they will settle in areas of the pipeline where the water flow rate is low. Over time, this sedimentation will accumulate and create resistance to the flow of circulating water. Therefore, a filter screen 13 is installed in the water replenishment chamber 10. While replenishing water, some of the scale and impurities are filtered out and guided through the filter screen 13 into the collection tank 15 via the sedimentation pipe 14. Staff only need to replace the collection tank 15 periodically. Considering that the entire circulation pipeline cannot be shut off during the replacement of the collection tank 15, a butterfly valve 16 is installed in the middle of the sedimentation pipe 14. The butterfly valve 16 can be closed when replacing the collection tank 15.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
