Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a water meter capable of being equipped with a sensor. Background Art

[0002] With the widespread adoption of water meter control systems, the installation of pressure and temperature sensors on water meters has also become increasingly common. Their primary functions are: if the pressure is detected as excessively high, it indicates a potential burst in the water supply system, requiring manual intervention; if the pressure is detected as too low, it indicates a leak in the section of the water supply system connected to the water meter, requiring on-site inspection and repair. If the temperature is detected as excessively high, there are generally two possible scenarios. One is that someone may have deliberately heated the water meter, softening the plastic and slowing the meter pointer. In this case, manual intervention is required, with a record kept as evidence. Another more common scenario is that water meters rated T30 are only rated for temperatures below 30°C, while T50 is rated for temperatures below 50°C. If the outdoor temperature exceeds the meter's operating range, manual intervention, such as ventilation and cooling the meter or installing a sunshade, is required. If the temperature is detected as low as 5°C, manual on-site insulation is required to prevent freezing.

[0003] Existing water meters are equipped with pressure and temperature sensors, typically fixed to water pipes or within the meter housing. However, the actual use of water meters can be challenging. For example, some water meters may not be initially installed, but later discover the need for sensor installation. Others may have sensors installed, but after a period of use, find they are ineffective and waste energy, requiring removal. Others may wish to replace the pressure sensor with a temperature sensor, or vice versa, or increase the number of sensors from one to two, such as a pressure sensor and a temperature sensor, or reduce the number of sensors from two to one. These existing water meters cannot be disassembled or replaced.

[0004] The prior art also has some water meters that are equipped with pressure sensors and temperature sensors and are replaceable, but they rely on a compression spring to compress the baffle seal or push open the spring to allow water to enter the pipe to detect the pressure and / or water temperature. During actual use, if the water quality is poor, there are many impurities or the water pressure is low, the compression spring is easily corroded and its performance is affected. In addition, the inside of the compression spring of the movable seal or between the baffle and the sealing surface of the valve body is prone to slag, resulting in seal failure and leakage. Its working stability is poor and its service life is affected. In particular, the compression spring and the sealing structure need to be repaired and replaced, and the water supply must be stopped and the water meter end cover must be removed, which makes it inconvenient to repair or replace them. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a water meter capable of installing a sensor, which has the advantages of convenient and quick disassembly and replacement of the sensor, tight sealing and stable and reliable operation.

[0006] The technical solution of the present utility model is to provide a water meter capable of installing a sensor, comprising a water meter body, a water cavity shell of the water meter body or an inlet and outlet water pipe having a water pipe connector connected to the water in the water meter body, an outer end of the water pipe connector being connected to the inlet end of a ball valve, and the ball valve further having an outlet end for detachably connecting to a sensor mounting seat.

[0007] After adopting the above structure, the water meter capable of installing a sensor of the utility model has the following advantages:

[0008] Pressure sensors and / or temperature sensors can be installed according to actual needs to transmit the detected pressure values ​​and / or temperature values ​​to the water meter control system so that manual on-site processing and resolution of related issues can be timely carried out.

[0009] Since the sensor mounting base for installing the sensor is detachably mounted outside the water meter body, it can meet various needs. If it is not initially installed, and you find that you need to install a sensor later, you can install it at any time after closing the ball valve. If you have installed a sensor initially but find that it is not effective after a period of use and need to remove it, you can remove it at any time after closing the ball valve. For example, if you want to replace the pressure sensor with a temperature sensor, or replace the temperature sensor with a pressure sensor, or increase the number of sensors from one to two, such as a pressure sensor and a temperature sensor, or reduce the number of sensors from two to one, you can close the ball valve at any time to meet the above installation, removal, replacement, addition, or reduction of sensors. The removal, replacement, and installation of sensors are all convenient and quick.

[0010] Since a ball valve is used as a fixed seal instead of the movable seal in the above-mentioned prior art, even if the water quality is poor, there are many impurities or the water pressure is low, it will not have any negative impact on the seal, nor will it cause the seal to fail and leak. The seal is tight, that is, the sealing performance is stable, reliable and durable, and it has good working stability and a long service life.

[0011] Since the sensor mounting seat where the sensor can be installed is outside the water meter body, such as the water cavity shell or the water inlet pipe or the water outlet pipe, and is detachably connected to the ball valve, it is convenient to disassemble and install, and the ball valve has good sealing performance, so it is very convenient to repair and replace.

[0012] Furthermore, the water chamber housing has a threaded through hole connecting the inside and outside of the water chamber housing. The external threads of one end of a first water pipe straight-through connector are threadedly connected to the internal threads of the threaded through hole and sealed. The other end of the first water pipe straight-through connector is connected to the inlet of the ball valve and sealed. The outlet of the ball valve is connected to the sensor mounting seat and sealed. With this structure, the connection between the ball valve and the water chamber housing and the connection between the ball valve and the sensor mounting seat is more convenient and faster, and the sealing performance is improved.

[0013] Furthermore, the sensor-mountable water meter of the present invention further includes a pipe elbow connector, wherein the internal threads at one end of the pipe elbow connector are threadedly connected to and sealed with the external threads at one end of a first pipe straight connector, the internal threads at the other end of the pipe elbow connector are threadedly connected to and sealed with the external threads at the inlet end of a ball valve, the internal threads at the outlet end of the ball valve are threadedly connected to and sealed with the external threads at one end of a second pipe straight connector, and the external threads at the other end of the second pipe straight connector are threadedly connected to and sealed with the internal threads at one end of a sensor mounting base. With the above structure, due to the use of the pipe elbow connector for connection, the ball valve and the sensor mounting base are arranged parallel to the vertical surface of the water meter body, thereby enabling the sensor-mountable water meter of the present invention to have the advantages described above while relatively reducing the space occupied by the ball valve and the sensor mounting base. Furthermore, the connection between the ball valve and the water chamber housing and the connection between the ball valve and the sensor mounting base are made more convenient and faster, with better sealing performance, and the disassembly of the ball valve and the sensor mounting base is also more convenient.

[0014] Furthermore, a pressure sensor and / or a temperature sensor are mounted within the sensor mounting base. The pressure sensor is electrically connected to the water meter control system, and the temperature sensor is also electrically connected to the water meter control system. This structure not only satisfies the water meter control system's need to detect water pressure and temperature within the water meter, but also ensures a relatively stable and reliable connection structure.

[0015] Furthermore, the sensor's electrical connection to the water meter control system is wireless: the sensor mounting base includes a radio transmitter module that transmits the sensor's electrical signal to the water meter's remote control system. This structure meets the electrical connection requirements of a wireless remote water meter control system and further ensures operational stability and reliability.

[0016] Furthermore, the sensor and water meter control system are electrically connected via a wired connection: Multiple wires are connected to the top of the sensor mounting base, connecting the sensor's electrical signals to the water meter's wired control system. This structure meets the electrical connection requirements of a wired water meter control system and further ensures operational stability and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these specific embodiments are intended to facilitate understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various specific embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown.

[0028] The present invention provides a water meter capable of being installed with a sensor, including a water meter body 1. A water pipe connector 4, such as a first water pipe straight connector 41, is provided on a water cavity housing 11 or an inlet and outlet water pipe of the water meter body 1, communicating with water within the water cavity housing 11 or the inlet and outlet water pipes, i.e., the water in the water inlet pipe or the water outlet pipe. The outer end of the water pipe connector 4, such as the first water pipe straight connector 41, is connected to an inlet end 21 of a ball valve 2. The ball valve 2 further includes an outlet end 22 for detachably connecting to a sensor mounting base 3.

[0029] There is a threaded through hole 111 on the water chamber housing 11 that connects the inside and outside of the water chamber housing 11. The external thread at one end of a first water pipe straight-through joint 41 is screwed and sealed with the internal thread of the threaded through hole 111. The other end of the first water pipe straight-through joint 41 is connected to the inlet end 21 of the ball valve 2 and sealed. The outlet end 22 of the ball valve 2 is connected to the sensor mounting seat 3 and sealed.

[0030] The water meter of the utility model capable of installing a sensor also includes a water pipe elbow joint 42, the internal thread of one end of the water pipe elbow joint 42 is screwed and sealed with the external thread of one end of the first water pipe straight joint 41, the internal thread of the other end of the water pipe elbow joint 42 is screwed and sealed with the external thread of the inlet end 21 of the ball valve 2, the internal thread of the outlet end 22 of the ball valve 2 is screwed and sealed with the external thread of one end of a second water pipe straight joint 43, and the external thread of the other end of the second water pipe straight joint 43 is screwed and sealed with the internal thread of one end of the sensor mounting base 3.

[0031] A pressure sensor and / or a temperature sensor is installed in the sensor mounting seat 3. It is not difficult to understand that here, or / and means: a pressure sensor is installed in the sensor mounting seat 3, or a temperature sensor is installed in the sensor mounting seat 3, or a pressure sensor and a temperature sensor are installed in the sensor mounting seat 3.

[0032] The pressure sensor is electrically connected to the water meter control system, and the temperature sensor is also electrically connected to the water meter control system, that is, the pressure sensor and the temperature sensor are each electrically connected to the water meter control system.

[0033] The electrical connection between the sensor and the water meter control system can be a wireless connection: the sensor mounting base 3 has a radio transmission module that transmits the sensor's electrical signal to the water meter remote control system. The pressure sensor and the temperature sensor each have a radio transmission module that transmits the sensor's electrical signal to the water meter remote control system.

[0034] The sensor and water meter control system can also be electrically connected via a wired connection: The top of the sensor mounting base is connected to multiple wires 3221 that connect the sensor's electrical signals to the water meter's wired control system. The pressure sensor and temperature sensor each have multiple wires 3221 connected to the water meter's wired control system.

[0035] The invention of the present utility model mainly lies in that the sensor mounting base 3 is detachably connected to the outlet end 22 of the ball valve 2. When the sensor needs to be installed, replaced, added or removed, the screws of the top cover 311 of the sensor mounting base 31 on which the wireless transmitter module is installed are loosened and the top cover 311 is removed, or the upper cylinder 321 of the sensor mounting base 32 on which the wired connection wire is installed are loosened and restored after the operation is completed.

[0036] The structures of the sensors within the sensor mounting base 3 are all conventional. For example, the pressure sensor, temperature sensor, and circuitry can be located in the upper portion of the sensor mounting base 3. The contacts, or probes, of the pressure and temperature sensors can be inserted into the water in the sealed lower water chamber within the sensor mounting base 3. For example, the pressure sensor and / or temperature sensor, as well as the wireless transmitter module, in the wireless connection structure can be electrically connected to a battery within the sensor mounting base 31, which houses the wireless transmitter module, and powered by the battery. For another example, the pressure sensor and / or temperature sensor in the wired electrical connection structure can be connected to the power supply of the water meter's wired control system via a power supply conductor, or power supply conductor 3221, and powered by the power supply conductor 3221. Furthermore, the pressure sensor and temperature sensor each have their own data conductor, or data conductor 3221, for electrical signal communication with the water meter's wired control system. The power and data conductors 3221 can be enclosed within the same cable 322.

[0037] The pressure sensor can be a conventional pressure sensor module, the temperature sensor can be a conventional temperature sensor module, and the conventional wireless transmitter module includes a pressure sensor transmitter module and a temperature sensor transmitter module. It is readily understood that the pressure sensor module, temperature sensor module, pressure sensor transmitter module, and temperature sensor transmitter module can be integrated into a single module.

[0038] It is not difficult to understand that in actual use, there is a situation where the outlet end 22 of the ball valve 2 is neither equipped with a sensor mounting seat 31 with a wireless transmitter module nor equipped with a sensor mounting seat 32 with a wired connecting wire, that is, there is no sensor mounting seat 3 at the outlet end of the ball valve, that is, no sensor is installed.

[0039] It is not difficult to understand that the connection and sealing described above refer to connection after the internal and external threads are screwed together to allow water to flow through, and sealing generally refers to sealing after the internal and external threads are tightened. Of course, sealing tape can also be wrapped around the internal and external threads to seal. For ease of expression, the first water pipe straight joint 41, the water pipe elbow joint 42, and the second water pipe straight joint 43 are collectively referred to as the water pipe connector 4. The water pipe elbow joint 42 is also called a water pipe elbow or an elbow. The water pipe straight joint is also called a water pipe straight or a straight. The inlet and outlet pipes are water inlet pipes or water outlet pipes. The threaded through hole is provided on the water inlet pipe and is connected to the water in the water inlet pipe, or the threaded through hole is provided on the water outlet pipe and is connected to the water in the water outlet pipe. Both are within the scope of protection of the present utility model.

The drawings are for illustration only. If there is any inconsistency between the drawings and the text description or between the drawings, the text description shall prevail.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
