Description

Technical Field

[0001] This utility model relates to the field of buffer technology, specifically a pressure-stabilizing buffer for a water tank inlet pipe that prevents fluctuations. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN220205046U, which discloses a pressure buffer for an industrial water supply pipeline, specifically relating to the field of pressure buffer technology. The buffer includes a circular shell, a head pipe, and an end pipe. The buffer structure designed in this invention consists of three parts: the end pipe, the circular shell, and the head pipe. Water enters and passes sequentially through the interiors of the end pipe, the circular shell, and the head pipe. By sequentially arranging a first buffer mechanism, a second buffer mechanism, and a third buffer mechanism inside the end pipe, the water pressure can be buffered in multiple stages upon entry, improving the buffering effect. The existing technical solutions described above have the following drawbacks: the spring is in direct contact with the water flow, and prolonged use inevitably leads to rust, affecting the spring's performance and resulting in poor buffering effect. Furthermore, disassembly is inconvenient, and repair is troublesome when damaged. Therefore, a pressure-stabilizing buffer for the inlet pipe of a water tank that prevents water fluctuations is proposed to solve the aforementioned problems. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a pressure-stabilizing buffer for the water tank inlet pipe to prevent fluctuations, which has the following beneficial effects:

[0015] This anti-fluctuation water tank inlet pipe pressure stabilizing buffer, through the setting of a support mechanism, a fixing mechanism, and a buffer mechanism, inserts the base into the bottom of the first pipe body, slides the U-shaped plate from the outside of the outer frame, so that the limiting block and the inclined surface of the wedge block are in contact. During installation, the base is pushed upwards, and when the wedge block contacts the limiting block, it will squeeze it outwards and drive the U-shaped plate to move. When the vertical plate moves to the top position, the right-angle plate is locked into the vertical plate, the wedge block is located on top of the limiting block and is in contact with it, and the tension of the telescopic spring pushes the U-shaped plate to return to its original position, completing the locking. It is confirmed that the limiting block and the wedge block are in tight contact without any loose gaps. During disassembly, simply pull the vertical rod, so that the connecting rod drives the U-shaped plate to compress the telescopic spring. The restriction on the vertical plate can be lifted, and the support and buffer mechanisms can be disassembled as a whole. Through the three-stage buffering of buffer block, buffer spring compression and support cylinder limiting, the impact energy is efficiently absorbed. When the water flow enters the first pipe and causes fluctuations, the buffer block directly contacts the water flow. Since the buffer block is attached to the inner wall of the first pipe, it can withstand the impact force of the water flow over a large area, disperse the impact energy of the water flow, and avoid excessive local stress, thereby effectively buffering the water flow fluctuations. The buffer spring is set inside the bottom cylinder and the movable cylinder to avoid direct contact with the water flow. The sealing ring effectively prevents water flow from leaking to the bottom of the buffer block, achieving the purpose of preventing the spring from rusting and facilitating disassembly.

Detailed Implementation

[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 1-6 This utility model provides a technical solution: a pressure-stabilizing buffer for a water tank inlet pipe to prevent water flow fluctuations, including a first pipe body 1. The first pipe body 1 serves as the main cavity for water flow buffering, providing installation space for the buffer mechanism 7 and guiding water flow from the inlet pipe 3 to the outlet pipe 4. A second pipe body 2 extending to the left side of the inner wall of the first pipe body 1 is fixedly installed. The inlet pipe 3 is movably installed on the top of the first pipe body 1. When water flows into the first pipe body 1 from the inlet pipe 3, the water flow is stopped at the bend between the first pipe body 1 and the second pipe body 2. The direction of the water flow will change. According to the principles of fluid mechanics, the change in the direction of the water flow will convert some of the kinetic energy in the water flow into internal energy, thereby reducing the flow velocity and impact force of the water flow. The buffering effect is further improved by the cooperation of the buffering mechanism 7. The outlet pipe 4 is movably installed on the left side of the second pipe body 2. The bottom of the first pipe body 1 is provided with a support mechanism 5 extending to its inner side. The front and rear sides of the first pipe body 1 are provided with fixing mechanisms 6 located outside the support mechanism 5. The inner side of the support mechanism 5 is provided with a buffering mechanism 7 that fits against the inner side of the first pipe body 1.

[0025] The support mechanism 5 includes a base 51. The base 51, which extends to the inside of the first tube 1, is movably installed at the bottom of the first tube 1. Vertical plates 52 are fixedly installed on both the front and rear sides of the base 51. Two wedge-shaped blocks 53 are fixedly installed on the side of the vertical plate 52 away from the first tube 1.

[0026] The fixing mechanism 6 includes an outer frame 61. The outer frame 61 is fixedly installed on both the front and rear sides of the first tube 1. One end of the top of the vertical plate 52 extends to the top of the outer frame 61. The wedge block 53 is located inside the outer frame 61. A U-shaped plate 62 extending to the outside of the outer frame 61 is slidably installed on the inner side of the outer frame 61. Two limiting blocks 63, which are respectively attached to the bottom of the two wedge blocks 53, are fixedly installed on one side of the U-shaped plate 62. A telescopic spring 64 fixedly connected to the inner wall of the outer frame 61 is fixedly installed on the inner wall of the U-shaped plate 62. A connecting rod 65 extending to the outside of the outer frame 61 is fixedly installed on the inner wall of the U-shaped plate 62. One end of the connecting rod 65 is fixedly installed with a vertical rod 66 fixedly connected to the U-shaped plate 62. A right-angle plate 67 that is engaged with the vertical plate 52 is fixedly installed on the top of the U-shaped plate 62.

[0027] The top of the wedge block 53 is inclined, the bottom of the limiting block 63 is inclined, one side of the vertical plate 52 has a groove that matches the right angle plate 67, the interior of the outer frame 61 is hollow, the outside of the vertical rod 66 is wrapped with a sponge sleeve, and one side of the inner wall of the outer frame 61 has a through hole that matches the connecting rod 65.

[0028] The buffer mechanism 7 includes support cylinders 71. Two support cylinders 71 are fixedly installed on the inner bottom wall of the base 51. An extension plate 72 extending to the top of the support cylinder 71 is slidably installed on the inner side of the support cylinder 71. The mounting groove of the support cylinder 71 restricts the extension plate 72 to slide only vertically, preventing the buffer block 73 from shifting under pressure and causing sealing failure. A buffer block 73, which is in contact with the inner wall of the first pipe body 1, is fixedly installed between the tops of the two extension plates 72. It directly bears the impact of the water flow, absorbs part of the kinetic energy through its own deformation, and reduces the instantaneous pressure of the water flow. The maximum depth of the buffer block 73 is controlled by the depth of the mounting groove. The large downward displacement distance avoids excessive compression of the buffer spring 77. A sealing ring 74 is movably installed on the outer side of the buffer block 73. It is made of highly elastic material to adapt to the frequent deformation of the buffer block 73 and extend the sealing life. A bottom cylinder 75 is fixedly installed on the inner bottom wall of the base 51. A movable cylinder 76 extending to the top of the bottom cylinder 75 and fixedly connected to the bottom of the buffer block 73 is slidably installed on the inner side of the bottom cylinder 75. A buffer spring 77 is fixedly installed between the inner bottom wall of the bottom cylinder 75 and the inner top wall of the movable cylinder 76. The remaining impact force transmitted by the buffer block 73 is absorbed through elastic deformation, further smoothing the water pressure fluctuation.

[0029] The support cylinder 71 has an internal mounting groove that matches the extension plate 72, and the bottom cylinder 75 has a circular groove on its top that matches the movable cylinder 76.

[0030] During use, connect the inlet pipe 3 to the water source pipe, ensuring a tight seal with the threads or flange. Connect the outlet pipe 4 to the water tank inlet, again checking for a tight seal. Insert the base 51 into the bottom of the first pipe body 1, ensuring the wedge blocks 53 on both sides of the vertical plate 52 face outwards, so that the limiting block 63 fits against the inclined surface of the wedge block 53. Simultaneously, the right-angle plate 67 is inserted into the groove of the vertical plate 52. Pull the vertical rod 66, which, through the connecting rod 65, drives the U-shaped plate 62 to compress the telescopic spring 64. Confirm that the limiting block 63 and the wedge block 53 are in tight contact without any looseness or gaps. Confirm that the buffer block 73 is located in the middle of the first pipe body 1 without any offset or jamming. Check whether the pre-compression of the telescopic spring 64 and the buffer spring 77 meets the design requirements. Slowly open the water inlet valve and observe whether the movement of the buffer block 73 is smooth. There should be no abnormal vibration or impact sound. Use a pressure gauge to monitor the water pressure fluctuation range of the outlet pipe 4 to ensure that it meets the pressure stabilization requirements. Disassemble the buffer every 3-6 months to remove scale or impurities from the surface of the buffer block 73 and the sealing ring 74 to prevent seal failure. Check whether there are deposits in the support cylinder 71 and the bottom cylinder 75. If necessary, rinse with clean water. Check the elastic coefficient of the buffer spring 77 and the extension spring 64 annually. If the spring force decreases by more than 20%, it needs to be replaced. Check the wear of the wedge block 53 and the limit block 63. If the wear of the inclined surface causes the contact area to decrease, the parts need to be repaired or replaced. Apply 0.5MPa air pressure to the end of the inlet pipe 3 and observe the pressure drop after holding the pressure for five minutes. If the pressure drop is >0.02MPa, check whether there is a leak in the sealing ring 74 or the pipe connection.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] In summary, this anti-fluctuation water tank inlet pipe pressure stabilizing buffer, through the setting of support mechanism 5, fixing mechanism 6, and buffer mechanism 7, inserts base 51 into the bottom of the first pipe body 1, slides U-shaped plate 62 from the outside of outer frame 61, so that limiting block 63 and wedge block 53 are in contact. During installation, push base 51 upward, and when wedge block 53 contacts limiting block 73, it will squeeze it outward and drive U-shaped plate 62 to move. When vertical plate 52 moves to the top position, right angle plate 67 is inserted into vertical plate 52, wedge block 53 is located at the top of limiting block 63 and is in contact with it. The tension of telescopic spring 64 pushes U-shaped plate 62 to reset, completing the snap-fit. Confirm that limiting block 63 and wedge block 53 are in tight contact without loose gaps. During disassembly, simply pull vertical rod 66, so that connecting rod 65 drives U-shaped plate 62 to compress telescopic spring 64, which can release the restriction on vertical plate 52. The impact mechanism 7 is disassembled as a whole. Through the three-stage buffering of buffer block 73, buffer spring 77 compression and support cylinder 71 limiting, the impact energy is efficiently absorbed. When the water flow enters the first pipe body 1 and causes fluctuations, the buffer block 73 is in direct contact with the water flow. Since the buffer block 73 is attached to the inner wall of the first pipe body 1, it can withstand the impact force of the water flow over a large area, disperse the impact energy of the water flow, and avoid excessive local stress, thereby effectively buffering the water flow fluctuations. The buffer spring 77 is set inside the bottom cylinder 75 and the movable cylinder 76 to avoid direct contact with the water flow. The sealing ring 74 effectively prevents water flow from leaking to the bottom of the buffer block 73, achieving the purpose of preventing the spring from rusting and facilitating disassembly. This solves the problem that the spring is in direct contact with the water flow, and rust will inevitably occur after long-term use, affecting the use of the spring, resulting in poor buffering effect, inconvenience in disassembly, and troublesome repair when damaged.
