Description

Technical Field

[0001] This utility model relates to the field of valve-controlled water meter technology, and in particular to a direct drinking water valve-controlled water meter. Background Technology

[0002] Chinese patent application CN202322068271.8 discloses a valve-controlled water meter; it includes a water meter body with a valve body at its bottom, and a telescopic assembly. Connecting pipes are fixedly connected to both sides of the valve body, and the telescopic assembly is located at the other end of the connecting pipes, connecting to a water pipe. The telescopic assembly includes a first pipe fixedly connected to the connecting pipes, a second pipe body inside the first pipe body, and the second pipe body being longer than the first pipe body. The second pipe body can move axially along the first pipe body within the first pipe body. A first locking component is located at the end of the first pipe body away from the connecting pipe, used to fix the second pipe body within the first pipe body. A second locking component is located at the end of the second pipe body away from the first pipe body. Its advantage is that the water meter can automatically adjust the length of the connecting parts, making installation more convenient.

[0003] After the aforementioned ring is tightened and fixed, the conical sealing ring will press against the second tube. Therefore, when adjusting the length of the second tube, the ring needs to be loosened, which is very inconvenient. Furthermore, the conical sealing ring alone cannot effectively seal the gap between the first and second tubes. Utility Model Content

[0004] To address the shortcomings of the comparative literature, this utility model provides a direct drinking water valve control meter, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a direct drinking water valve-controlled water meter, including a water meter body, a valve body installed below the water meter body, connecting pipes disposed on both outer sides of the valve body, and a first pipe body disposed on one side of the connecting pipe. A ring body is threaded onto the outer side of one end of the first pipe body, and a second pipe body is disposed inside the ring body. A first sealing ring is disposed on the inner side of the ring body and located outside the second pipe body. A second sealing ring is disposed on the outer side of one end of the second pipe body and located inside the first pipe body. A corrugated pipe is disposed between the first sealing ring and the second sealing ring and located between the first pipe body and the second pipe body. A fixing sleeve is threaded onto the inner side of one end of the second pipe body and located on one side of the second sealing ring. A nut is threaded onto the outer side of the second pipe body and located outside the ring body. A guide groove is provided on the outer side of the second pipe body.

[0006] Preferably, one side of the ring body is provided with L-shaped plates that are symmetrically distributed and located outside the nut.

[0007] Preferably, a hexagonal prism is provided on the outer side of the end of the second tube away from the ring.

[0008] Preferably, the inner side of the ring body is provided with a limiting boss that matches the guide groove.

[0009] This utility model has the following advantages:

[0010] 1. By rotating the nut, the second tube can be moved along its own axis, and the bellows can be stretched or compressed through the second sealing ring. This allows for direct adjustment of the length of the second tube extending beyond the outer side of the first tube, making the operation very convenient.

[0011] 2. The cooperation of the first sealing ring, the second sealing ring, and the bellows ensures that the second pipe body can always seal the gap between the first pipe body and the second pipe body during movement. Furthermore, the cooperation of the guide groove and the limiting boss can limit the second pipe body, preventing it from rotating during movement. This avoids the first sealing ring, the second sealing ring, and the bellows from twisting or deforming, thus effectively sealing the gap between the first pipe body and the second pipe body.

[0018] 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.

[0019] Please see Figures 1 to 5 A direct drinking water valve-controlled water meter includes a water meter body 1, a valve body 2 installed below the water meter body 1, connecting pipes 3 located on both outer sides of the valve body 2, and a first pipe body 4 located on one side of the connecting pipes 3. A ring body 5 is threaded onto the outer side of one end of the first pipe body 4, and a second pipe body 6 is fitted inside the ring body 5. A first sealing ring 7 located on the outer side of the second pipe body 6 is fitted onto the inner side of the ring body 5, and a second sealing ring 8 located on the inner side of the first pipe body 4 is fitted onto the outer side of one end of the second pipe body 6. The second sealing ring 8 seals the gap between the first pipe body 4 and the second pipe body 6. A bellows 9 is located between the first sealing ring 7 and the second sealing ring 8, allowing the second sealing ring 8 to move as it follows the second pipe body 6. Displacement compensation is achieved through the stretching or compression of the bellows 9, thereby ensuring that the first sealing ring 7, the second sealing ring 8, and the bellows 9 are always connected together while sealing the gap between the first pipe body 4 and the second pipe body 6. A fixing sleeve 10 located on one side of the second sealing ring 8 is fitted with the internal thread at one end of the second pipe body 6. The fixing sleeve 10 can press and fix the second sealing ring 8, so that the second sealing ring 8 can move synchronously with the second pipe body 6 during the movement. The fixing sleeve 10 can be removed to release the restriction on the second sealing ring 8, so as to facilitate the disassembly and assembly of the first sealing ring 7, the second sealing ring 8, and the bellows 9. A nut 11 located on the outside of the ring body 5 is threaded onto the outside of the second pipe body 6, and a guide groove 12 is opened on the outside of the second pipe body 6.

[0020] One side of the ring body 5 is provided with an L-shaped plate 13 that is symmetrically distributed and located outside the nut 11. The L-shaped plate 13 can limit the nut 11, so that the nut 11 can drive the second tube 6 to move along its own axis during rotation. This allows for quick adjustment of the length of the second tube 6 extending outside the first tube 4. The L-shaped plate 13 will not interfere with the installation of the nut 11, making it easy to assemble and disassemble the ring body 5 and the nut 11.

[0021] Among them, a hexagonal post 14 is provided on the outer side of the end of the second pipe body 6 away from the ring body 5. The hexagonal post 14 allows the second pipe body 6 to be limited by a wrench when connected to an external water pipe, ensuring that the second pipe body 6 will not rotate and preventing the ring body 5 from loosening, so that the first sealing ring 7 can seal the gap between the first pipe body 4 and the ring body 5.

[0022] The inner side of the ring body 5 is provided with a limiting boss 15 that is adapted to the guide groove 12. The cooperation between the guide groove 12 and the limiting boss 15 enables the ring body 5 to limit and support the second tube body 6 while limiting the second tube body 6, so that the second tube body 6 can only move along its own axis during the rotation of the nut 11.

[0023] Working principle: When adjusting the extension length of the second tube 6, use a wrench to rotate the nut 11. The rotation of the nut 11 can drive the second tube 6 to move along its own axis, while the second sealing ring 8 stretches or compresses the bellows 9. When the extension length of the second tube 6 is adjusted, stop rotating the nut 11. At this time, the nut 11 can limit and fix the second tube 6, and its extension length will not retract on its own.
