Description

Technical Field

[0001] The utility model relates to the technical field of circulating water pumps, in particular to a reducing energy-saving variable-diameter pipeline structure for a circulating water pump. Background Art

[0002] Pipelines are usually used to transport fluids such as gases or liquids. During the process of transporting water flow, pipelines generally rely on equipment such as circulating water pumps to provide pressure to push the water flow to flow rapidly.

[0003] When the circulating water pump is in the closed state, the liquid may flow back due to gravity and pressure difference. This backflow not only causes energy loss in the system but may also trigger a series of problems, such as water hammer effect and equipment wear, thereby increasing the maintenance cost. The occurrence of the backflow phenomenon makes the pump consume additional energy to re-establish the system pressure when starting again, thus reducing the overall energy efficiency.

[0004] Therefore, we propose a reducing energy-saving variable-diameter pipeline structure for a circulating water pump. Content of the Utility Model

A slot is opened at one end of the energy-saving pipeline. First positioning grooves are opened at both the upper and lower ends of the energy-saving pipeline. An installation ring is provided at one end inside the energy-saving pipeline. Plug blocks are fixed at both the top and bottom of the installation ring. Second positioning grooves are opened on the plug blocks. Sealing plates are hinged on the inner walls of the installation ring. Blocking blocks are fixedly connected to the outer side walls of the bottoms of the plug blocks. Baffles are fixedly connected to both the left and right ends inside the inner cavity of the installation ring.

[0007] Preferably, installation frames are fixed at both ends of the energy-saving pipeline. Through holes and limiting grooves are respectively opened on both side walls of the installation frames. A pull rod slides in the through hole. A pull ring and a limiting plate are respectively fixed at both ends of the pull rod. A return spring is sleeved on the pull rod. A limiting rod penetrates through the limiting groove.

[0008] Preferably, the limiting groove, the limiting rod, the first positioning groove, and the second positioning groove are all of a cross-shaped structure and are mutually adapted.

[0009] Preferably, the sealing plate is of a semi-circular arc structure, and the blocking block is of a trapezoidal structure.

[0010] Preferably, the baffle is arranged at both the left and right ends inside the inner cavity of the installation ring and is located at the junction of the two sealing plates.

[0011] Preferably, one end of the limiting rod close to the limiting plate is fixedly connected to the limiting plate, and the upper and lower wall surfaces of the limiting plate are attached to the upper and lower wall surfaces of the inner cavity of the installation frame.

[0023] Embodiment: A reducing energy-saving variable-diameter pipe structure for a circulating water pump, as Figures 1-3As shown in the figure, it includes a circulating water pump 1 and a water outlet pipe 101. The water outlet end of the water outlet pipe 101 is connected to an energy-saving pipe 2. A plurality of guide columns 201 are circumferentially distributed on the inner cavity wall surface of the energy-saving pipe 2. At one end of the inner cavity of the energy-saving pipe 2 away from the water outlet pipe 101, there is an installation ring 3. Plug blocks 5 are fixedly connected to both the top and bottom of the installation ring 3. On the inner cavity wall surface of the installation ring 3, sealing plates 301 with a semi-circular arc structure are hinged. Trapezoidal blocks 6 are fixedly connected to the bottom of the plug blocks 5 and on the outer wall surface of the sealing plates 301. Baffles 7 are fixedly connected to both the left and right ends of the inner cavity of the installation ring 3 and at the junction of the two sealing plates 301. Without external force, the wall surface of the sealing plate 301 fits with the wall surface of the baffle 7. Slots 203 are opened at positions corresponding to the plug blocks 5 at one end of the energy-saving pipe 2 away from the water outlet pipe 101. Second positioning grooves 501 are opened on both plug blocks 5. First positioning grooves 202 are opened at positions on the upper and lower ends of the two energy-saving pipes and adapted to the second positioning grooves 501. Installation frames 4 are fixedly connected to the upper and lower ends of the two energy-saving pipes and at positions corresponding to the first positioning grooves 202. Through holes 401 are opened on one side of the two installation frames 4 away from the first positioning grooves 202. Pull rods 402 adapted to the through holes 401 are slidably arranged in the inner cavities of the through holes 401. Pull rings 403 are fixedly connected to the ends of the pull rods 402 located outside the installation frames 4. Return springs 404 are sleeved on the pull rods 402 and in the inner cavities of the installation frames 4. Limit plates 405 are fixedly connected to one ends of the pull rods 402 and in the inner cavities of the installation frames 4. The upper and lower wall surfaces of the limit plates 405 are in contact with the upper and lower wall surfaces of the inner cavities of the installation frames 4. Limit grooves 406 are opened on the side walls of the installation frames 4 away from the through holes 401. Limit rods 407 penetrate through the inner cavities of the limit grooves 406.

[0024] The working principle of the present utility model:

[0025] During use, under the impact force of the liquid, the two sealing plates 301 are in an open state, and the water flow passes through. When the circulating water pump 1 is turned off, the circulating water pump 1 no longer discharges water. At this time, the sealing plates 301 cooperate with the baffles 7 and are in a closed state, reducing the probability of water flowing back in the circulating water pump 1.

[0026] During use, by pulling the pull ring 403, the limit plate 405 squeezes and contracts the return spring 404. At this time, the installation ring 3 is taken out from the inner cavity of the energy-saving pipe 2, realizing the rapid installation and disassembly of the energy-saving pipe 2 and the installation ring 3.

[0027] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be oriented "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be oriented in other different ways (rotated 90 degrees or at other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0028] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0029] The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
