Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a valve-controlled water meter which is convenient for assembly and disassembly. Background Art

[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. The internal structure of a water meter can be divided into three parts from the outside to the inside: the shell, the sleeve, and the inner core. After the water comes out of the water inlet, it passes through the lower annular space of the shell, which is called the "lower annular chamber". Above this annular space is the "upper annular chamber" which is connected to the water outlet. The inner core is divided into three layers: upper, middle, and lower. The upper layer is visible from the glass window, which only has a pointer and a dial. The most important is the lower layer, which has a plastic wheel with many plastic blades on the edge of the wheel, called an "impeller". The position of the impeller is just in the rotating flow formed by the lower hole of the sleeve. The water flow impacts the blades around the wheel, generating torque, which makes the impeller rotate. The wider the faucet is opened, the faster the water flow, and the faster the impeller rotates.

[0003] The existing water meter connection method usually uses a threaded sleeve to connect the water meter to the pipeline. In order to ensure the sealing, the number of threads of the threaded sleeve is relatively long, and more time is spent on rotating the threaded connection part during the disassembly process, so that quick disassembly and assembly cannot be achieved. There are quick connectors in the existing technology, but due to the internal structure of the quick connector, it cannot be used in large-flow pipelines. To this end, we provide a valve-controlled water meter that is easy to disassemble and assemble to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a valve-controlled water meter that is easy to disassemble and assemble, comprising a valve-controlled water meter 1, wherein rotating grooves 2 are arranged at both ends of the valve-controlled water meter 1, a rotating ring 3 is rotatably connected inside the rotating groove 2, and a connecting disk 4 that is connected by a rotating clamp is fixedly installed at one end of the rotating ring 3 away from the valve-controlled water meter 1.

[0025] One of the rotating rings 3 is connected to and penetrated by a bellows 7, which is located outside the valve-controlled water meter 1. Such an arrangement enables the installation and connection of two pipes that are not on the same horizontal line.

[0026] The two ends of the valve-controlled water meter 1 are fixedly installed with connecting flanges 5, and the outer surface of the connecting flange 5 is sleeved with a sealing ring 6. The processing method of directly sleeve-connecting the connecting flange 5 between the valve-controlled water meter and the existing pipeline through the sealing ring 6 is faster.

[0027] The sealing ring 6 includes a bottom half ring 601 and a wrapping half ring 602 hinged on both sides of the bottom half ring 601. A rubber strip 603 is fixedly installed inside the sealing ring 6, and a clamping sleeve 604 is fixedly installed on the top of the wrapping half ring 602. The two clamping sleeves 604 are clamped together by a clamping shaft 605. Through such an arrangement, the sealing ring 6 can be sleeved on the connected port, thereby playing a sealing role.

[0028] The top of the wrapping half ring 602 is provided with a dislocated notch, and the end face of the rubber strip 603 is parallel to the end face of the notch. Such a setting can make the notch of the rubber strip 603 in a dislocated state and thus provide a more effective seal.

[0029] The end surface of the connection disk 4 is provided with a rotational plug-in slot 401 , and a rotational plug-in block 402 is fixedly mounted on the end surface of the connection disk 4 . By plugging adjacent rotational plug-in blocks 402 into the rotational plug-in slot 401 and rotating them, quick connection can be achieved.

[0030] Working principle: The valve-controlled water meter 1 can be connected to the waterway by plugging and rotating the connecting disk 4 with the existing connecting disk 4 through the rotating plug-in groove 401 and the rotating plug-in block 402, and the bottom half ring 601 is sleeved under the two connecting disks 4, and the rotating wrapped half ring 602 is sleeved on the outer ring of the connecting disk 4, and is clamped between the two clamping sleeves 604 through the clamping shaft 605 so that the two wrapped half rings 602 are close to each other and squeeze the rubber strip 603 for sealing.
