Description

Technical Field

[0001] This application relates to the field of water meters, and more particularly to an adjustable water meter. Background Technology

[0002] A water meter is an instrument used to measure and record water flow, commonly found in homes, commercial establishments, and public facilities. A water meter consists of a meter core and a meter casing. The meter core measures the flow of fluid passing through the meter. Currently, water meters are designed at the factory to ensure that the flow rate passing through the meter equals the value measured by the meter core, thus guaranteeing the meter's accuracy.

[0003] However, after prolonged use, the water meter core may become malfunctioning or damaged, leading to inaccurate meter readings. Generally, water meters with inaccurate readings are discarded, resulting in a waste of resources. Utility Model Content

[0004] In order to extend the service life of water meters, this application provides an adjustable water meter.

[0005] The adjustable water meter provided in this application adopts the following technical solution:

[0006] An adjustable water meter includes a housing, a retaining ring, and an adjusting component. One end of the housing is provided with a receiving groove, and the retaining ring is fixedly connected to the groove wall. The outer wall of the housing is provided with a first connecting port, a second connecting port, and an auxiliary port. The first connecting port, the second connecting port, and the auxiliary port are all connected to the receiving groove. The first connecting port and the second connecting port are respectively located on both sides of the retaining ring. The second connecting port is located on the side of the retaining ring closer to the bottom of the receiving groove, and the auxiliary port is located on the side of the retaining ring away from the second connecting port. The adjusting component slides within the auxiliary port, and the adjusting component is used to adjust the opening and closing and the size of the auxiliary port.

[0007] By adopting the above technical solution, when the water meter reading is inaccurate, the regulating component adjusts the opening and closing of the auxiliary port to compensate for the water volume, so that the water flow rate of the water meter is equal to the measured flow rate, thus extending the service life of the water meter.

[0008] Preferably, it further includes a first connecting pipe, which is fixedly connected to the outer wall of the housing and communicates with a first communication port.

[0009] By adopting the above technical solution, the various components of the water meter are manufactured separately and then assembled, which improves the manufacturing efficiency of the water meter, and the first connecting pipe facilitates the guidance of water flow.

[0010] Preferably, it further includes a second connecting pipe, which is fixedly connected to the outer wall of the housing and communicates with the second connecting port and the auxiliary port.

[0011] By adopting the above technical solution, the various components of the water meter are manufactured separately and then assembled, which improves the manufacturing efficiency of the water meter, and the second connecting pipe facilitates the guidance of water flow.

[0012] Preferably, the adjusting component includes an installation tube and a ejector pin. The second connecting tube has an installation port. The installation tube is coaxially and fixedly connected to the inner wall of the installation port. The ejector pin is connected to the inner wall of the installation tube and moves within the installation tube. The ejector pin is used to extend into the auxiliary port.

[0013] By adopting the above technical solution, the installation pipe is fixed on the second connecting pipe, and an installation port is opened to facilitate the installation of the installation pipe. The pin moves inside the installation pipe to adjust the opening and closing of the auxiliary port and the size of the opening, which facilitates the control of water volume compensation, so that the flow rate is equal to the metering and extends the service life of the water meter.

[0014] Preferably, the mounting tube and the auxiliary port are coaxially arranged.

[0015] By adopting the above technical solution, the ejector pin and the mounting tube are coaxially arranged, which in turn makes it coaxial with the auxiliary port, facilitating the adjustment of the size of the auxiliary port, making it easier to control, and improving the adjustment efficiency.

[0016] Preferably, the ejector pin is threaded to the inner wall of the mounting tube.

[0017] By adopting the above technical solution, the ejector pin can rotate and move inside the installation tube, which facilitates the adjustment of the ejector pin's position, enables control over the opening and closing and size of the auxiliary port, and improves adjustment efficiency.

[0018] Preferably, the ejector pin includes a connecting post, a sealing post, and an adjusting post. The connecting post is threaded to the inner wall of the mounting tube. The sealing post is coaxially fixedly connected to one end of the connecting post. The adjusting post is coaxially fixedly connected to the end of the sealing post away from the connecting post. The diameter of the sealing post is equal to the diameter of the auxiliary port. The diameter of the adjusting post decreases as it moves away from the sealing post. The adjusting post is used to adjust the size of the auxiliary port.

[0019] By adopting the above technical solution, when the sealing column is slidably connected to the inner wall of the auxiliary port, water cannot flow out of the auxiliary port. The adjusting column slides inside the auxiliary port to adjust the amount of water passing through the auxiliary port. The adjustment accuracy is high and it is easy to use.

[0020] Preferably, the adjusting component further includes a sealing ring, and the outer wall of the connecting column is coaxially provided with a sealing ring groove, the inner wall of the sealing ring is embedded in the sealing ring groove, and the outer wall of the sealing ring abuts against the inner wall of the mounting tube.

[0021] By adopting the above technical solution, the sealing ring reduces the probability of water leakage from the installation pipe, thereby reducing water waste.

[0022] Preferably, there are multiple sealing rings, and the multiple sealing rings are spaced apart along the axis of the connecting column.

[0023] By adopting the above technical solution, multiple sealing rings further improve the sealing accuracy and prevent water leakage.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the water meter reading is inaccurate, the regulating component adjusts the opening and closing of the auxiliary port to compensate for the water volume, so that the water flow rate of the water meter equals the measured flow rate, thus extending the service life of the water meter.

[0026] 2. Fix the installation pipe to the second connecting pipe and open the installation port to facilitate the installation of the installation pipe. The pin moves inside the installation pipe to adjust the opening and closing of the auxiliary port and the size of the opening, which facilitates the control of water volume compensation, so that the flow rate is equal to the metering and extends the service life of the water meter.

[0027] 3. When the sealing column is slidably connected to the inner wall of the auxiliary port, water cannot flow out of the auxiliary port. The adjusting column slides inside the auxiliary port to adjust the amount of water passing through the auxiliary port. The adjustment accuracy is high and it is easy to use.
