Description

Technical Field

[0001] The utility model belongs to the technical field of water meter protection, and in particular relates to an adaptive sealing structure of a modular water meter. Background Art

[0002] A modular water meter is a water meter design that breaks down the water meter into modules that can be replaced or upgraded individually. This design makes it more convenient and flexible to maintain and manage the water meter, as modules with specific functions can be replaced or upgraded as needed without having to replace the entire water meter.

[0003] When using existing water meters, the water meter is installed between two water pipes through a flange, and a rubber sealing ring or similar sealing material is added between the flanges to ensure the sealing of the flange connection. However, due to factors such as water pipe contraction (if the pipe contracts suddenly, the water flow rate will increase, thereby increasing the pressure) and water pipe bending (when water flows through a bend in the water pipe, the pressure will increase due to inertia and centrifugal force), the pressure in the water pipe will increase. In this case, there will be problems of water pipe leakage or seepage, thereby wasting water resources. Utility Model Content

[0004] In order to solve the technical problem that water pipe pressure increases, causing water pipe leakage or water seepage, the utility model provides an adaptive sealing structure of a modular water meter.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] An adaptive sealing structure of a modular water meter comprises a water meter body, two ends of the water meter body are respectively connected with a water inlet pipe and a water outlet pipe through flanges, two connecting plates are arranged inside the water meter body, a side of the connecting plate close to the water inlet pipe is connected with a frame, and a sealing ring is arranged inside the frame;

[0007] A mounting plate is fixedly connected to the middle of the connecting plate, and a center column is rotatably connected to the middle of the mounting plate. A plurality of pressure plates in a circular array are arranged on the outer side of the center column, and an impact plate is obliquely connected to the side of the pressure plate close to the water inlet pipe. A plurality of outer shells in a circular array are arranged at the position of the connecting plate corresponding to the pressure plate, and a triangular block is slidably connected in the outer shell, and a side of the triangular block away from the pressure plate is connected to one end of a plurality of springs, and the other ends of the plurality of springs are connected to a connecting block, and an end of the connecting block away from the spring is connected to an arc plate.

[0008] Preferably, one of the connecting plates is fixedly connected to the inner wall of one end of the water meter body close to the water inlet pipe, and the other connecting plate is fixedly connected to the inner wall of one end of the water outlet pipe close to the water meter body.

[0009] Preferably, the sealing ring corresponds to the connection of the flange and is tightly attached to the flange.

[0010] Preferably, the triangular block fits with an end of the pressure plate away from the central column.

[0011] Preferably, the outer side of the triangular block is connected with symmetrically arranged sliding blocks, and the outer shell is provided with symmetrically arranged sliding grooves at positions corresponding to the sliding blocks, and the sliding blocks are slidably connected in the sliding grooves.

[0012] Preferably, the arc-shaped plate is in close contact with the inner side of the sealing ring.

[0013] Preferably, a first baffle is connected to a position of the outer shell away from the protruding portion of the triangular block, a second baffle is connected to a position of the outer shell close to the protruding portion of the triangular block, and the pressure plate is located between the first baffle and the second baffle.

[0014] Beneficial effects of the utility model:

[0015] When the water pressure in the water inlet pipe increases, the interaction force between the water molecules in the pipe is enhanced, so that the movement speed of the water molecules increases, and the flow rate also increases accordingly, so that the water will impact the impact plate. Under the impact of water, the impact plate will rotate with the central column as the center of the circle. The rotation of the impact plate drives the pressure plate to rotate. The pressure plate will squeeze the triangular block during the rotation process, so that the triangular block slides into the shell. The triangular block will squeeze the spring during the sliding process. The spring will shrink and store the restoring force when squeezed, and at the same time, the squeezing force will be transmitted to the connecting block, and then transmitted to the arc plate by the connecting block, so that the arc plate squeezes the sealing ring, so that the sealing ring is closer to the connection of the flange, preventing water from leaking or seeping from the connection of the flange, and avoiding the waste of water resources;

[0016] After the water pressure in the water inlet pipe drops, the impact force of water on the impact plate becomes smaller, thereby reducing the extrusion force of the pressure plate on the triangular block, the extrusion force of the triangular block on the spring, and the extrusion force of the spring on the connecting block and the arc plate. Under the action of the spring restoring force, the spring is restored, and the spring reset drives the triangular block, the connecting block and the arc plate to reset. After the arc plate is reset, the sealing ring will not be squeezed, thereby avoiding long-term squeezing of the sealing ring, which leads to a decrease in the service life of the sealing ring. During the resetting process of the triangular block, it will drive the pressure plate to reset to prepare for the next sealing. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 - Figure 7As shown, an adaptive sealing structure of a modular water meter includes a water meter body 11, and both ends of the water meter body 11 are connected to a water inlet pipe 1 and a water outlet pipe 12 through flanges, which are used to install the water meter body 11 and count the water consumption through the water meter body 11;

[0033] Two connecting plates 2 are arranged inside the water meter body 11, one of which is fixedly connected to the inner wall of one end of the water meter body 11 close to the water inlet pipe 1, and the other connecting plate 2 is fixedly connected to the inner wall of one end of the water outlet pipe 12 close to the water meter body 11, and the connecting plate 2 is used to connect the adaptive sealing structure;

[0034] A frame 21 is connected to one side of the connecting plate 2 close to the water inlet pipe 1. A sealing ring 211 is arranged inside the frame 21. The sealing ring 211 corresponds to the connection of the flange and is tightly attached to the flange. The sealing ring 211 is used to seal the water inlet pipe 1, the water meter body 11 and the water outlet pipe 12 to prevent water leakage.

[0035] The middle of the connecting plate 2 is fixedly connected with a mounting plate 3, and the middle of the mounting plate 3 is rotatably connected with a center column 31. The mounting plate 3 is used to connect with the center column 31, and the center column 31 is used to connect with the pressure plate 4.

[0036] A plurality of pressure plates 4 in a circumferential array are arranged outside the central column 31 to press the triangular block 42 so that the arc plate 46 presses the sealing ring 211;

[0037] An impact plate 41 is obliquely connected to one side of the pressure plate 4 close to the water inlet pipe 1. The impact plate 41 cooperates with the water flow to make the pressure plate 4 rotate clockwise.

[0038] A plurality of outer shells 43 in a circumferential array are provided at the position of the connecting plate 2 corresponding to the pressure plate 4, and a triangular block 42 is slidably connected inside the outer shell 43. The outer shell 43 is used to limit the position of the triangular block 42 to prevent the triangular block 42 from shifting;

[0039] The triangular block 42 is fitted with the end of the pressure plate 4 away from the central column 31, which can prevent the triangular block 42 from sliding freely in the housing 43;

[0040] The outer side of the triangular block 42 is connected with a symmetrically arranged slider 431, and the outer shell 43 is provided with a symmetrically arranged slide groove 432 at the position corresponding to the slider 431. The slider 431 is slidably connected in the slide groove 432. The slider 431 cooperates with the slide groove 432 to further limit the position of the triangular block 42, so that the triangular block 42 can slide smoothly in the outer shell 43, and prevent the triangular block 42 from warping.

[0041] The side of the triangular block 42 away from the pressure plate 4 is connected to one end of a plurality of springs 44, and the other ends of the plurality of springs 44 are all connected to a connecting block 45. The spring 44 is used to reset the positions of the triangular block 42, the pressure plate 4 and the impact plate 41. At the same time, compared with the direct connection between the triangular block 42 and the connecting block 45, adding the spring 44 between the triangular block 42 and the connecting block 45 can reduce the squeezing force of the arc plate 46 on the sealing ring 211, thereby extending the service life of the sealing ring 211.

[0042] The end of the connecting block 45 away from the spring 44 is connected with an arc plate 46, and the arc plate 46 is in close contact with the inner side of the sealing ring 211;

[0043] In specific use, when the water pressure in the water inlet pipe 1 increases, the interaction force between the water molecules in the pipe is enhanced, so that the movement speed of the water molecules increases, and the flow rate also increases accordingly, so that the water will impact the impact plate 41. Under the impact of water, the impact plate 41 will rotate with the central column 31 as the center of the circle. The rotation of the impact plate 41 drives the pressure plate 4 to rotate. During the rotation, the pressure plate 4 will squeeze the triangular block 42, so that the triangular block 42 slides into the shell 43. During the sliding process, the triangular block 42 will squeeze the spring 44. The spring 44 will shrink and store the restoring force when squeezed, and at the same time, the squeezing force will be transmitted to the connecting block 45, and then transmitted to the arc plate 46 by the connecting block 45, so that the arc plate 46 squeezes the sealing ring 211, so that the sealing ring 211 is closer to the connection of the flange, preventing water from leaking or seeping from the connection of the flange, and avoiding the waste of water resources;

[0044] After the water pressure in the water inlet pipe 1 drops, the impact force of water on the impact plate 41 becomes smaller, thereby reducing the extrusion force of the pressure plate 4 on the triangular block 42, the extrusion force of the triangular block 42 on the spring 44, and the extrusion force of the spring 44 on the connecting block 45 and the arc plate 46. Under the action of the restoring force of the spring 44, the spring 44 is restored, and the reset of the spring 44 drives the triangular block 42, the connecting block 45 and the arc plate 46 to reset. After the arc plate 46 is reset, the sealing ring 211 will not be squeezed, thereby avoiding long-term squeezing of the sealing ring 211, which leads to a decrease in the service life of the sealing ring 211. During the reset process of the triangular block 42, it will drive the pressure plate 4 to reset to prepare for the next sealing.

[0045] The first baffle plate 5 is connected to the position of the outer shell 43 away from the protruding part of the triangular block 42, and the second baffle plate 51 is connected to the position of the outer shell 43 close to the protruding part of the triangular block 42. The pressure plate 4 is located between the first baffle plate 5 and the second baffle plate 51. The first baffle plate 5 cooperates with the second baffle plate 51 to limit the rotation angle of the pressure plate 4 to prevent the pressure plate 4 from rotating arbitrarily and affecting the sealing of the sealing ring 211.
