Description

Technical Field

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

[0002] With the increasing demand for water resource management and the rapid development of smart water systems, traditional mechanical water meters are gradually being replaced by more accurate and feature-rich ultrasonic water meters. An ultrasonic water meter is a smart water meter that combines ultrasonic measurement technology. It mainly detects the time difference caused by the change in speed when the ultrasonic beam propagates in the water upstream and downstream, analyzes and processes the data to obtain the water flow rate, and then calculates the amount of water flowing through the pipe.

[0003] However, in some residential areas or industrial facilities, in order to achieve accurate water metering and management, it is often necessary to monitor and regulate the water supply in real time. The existing solution is usually to install valves on the water meter pipe.

[0004] However, ultrasonic water meters with valve control functions on the market generally suffer from poor sealing performance at the connection between the valve and the water inlet of the meter body. Especially after long-term operation, due to design defects or further aging of the sealing materials, water leakage is prone to occur, affecting the accuracy of the water meter, resulting in the inability to accurately measure water consumption and wasting water resources. In view of the above, it is necessary to develop a valve-controlled ultrasonic water meter. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing valve-controlled ultrasonic water meters are prone to poor sealing and leakage after long-term use, which affects the accuracy of metering and leads to water waste. Therefore, a valve-controlled ultrasonic water meter is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A valve-controlled ultrasonic water meter includes an ultrasonic meter body and a control valve mounted on the ultrasonic meter body. It further includes: a first sealing ring disposed on the ultrasonic meter body, wherein a connecting pipe is fixedly connected to the water inlet end of the ultrasonic meter body, and the first sealing ring is sleeved on the connecting pipe. When the connecting pipe is inserted into the interface of the control valve, the first sealing ring undergoes elastic deformation and abuts against the inner wall of the interface of the control valve; a second sealing ring is fixedly connected to the interface of the control valve, the edge of the second sealing ring being petal-shaped and forming an annular corrugated structure. Fasteners are provided on the connecting pipe, which are used to fix the control valve and the connecting pipe, causing the second sealing ring to undergo elastic deformation and seal the connection between the control valve and the connecting pipe.

[0008] To secure the control valve and the ultrasonic transducer and provide a sealing effect at the connection, preferably, the fastener includes a locking sleeve fixedly fitted on the connecting pipe, and a movable sleeve movably fitted on the control valve, wherein the locking sleeve and the movable sleeve are connected by a threaded component, and when the connecting pipe is inserted into the interface of the control valve, the second sealing ring abuts against the surface of the locking sleeve.

[0009] To achieve locking of the locking sleeve and the movable sleeve, the threaded component further includes a screw head fixedly connected to the movable sleeve, and the locking sleeve has a screw groove, with the screw head threadedly connected to the screw groove.

[0010] To improve the stability of the first sealing ring, preferably, the connecting pipe has a groove, and the first sealing ring is fixedly connected in the groove.

[0011] To ensure a tight seal, preferably, both the second sealing ring and the first sealing ring are made of fluororubber.

[0012] To facilitate insertion of the connecting pipe into the interface of the control valve, preferably, the port of the connecting pipe is provided with a rounded corner.

[0013] To facilitate the assembly and connection of the control valve and the connecting pipe, preferably, the diameter of the connecting pipe is smaller than the inner diameter of the control valve interface.

[0014] To ensure a tight fit between the first sealing ring and the inner wall of the control valve interface, preferably, the outer diameter of the first sealing ring is larger than the inner diameter of the control valve interface.

[0015] To facilitate the management and control of the water meter, the control valve is preferably an electric ball valve, an electric butterfly valve, or an electric regulating valve.

[0016] To further improve the friction of the movable sleeve surface, multiple protrusions are fixedly connected to the movable sleeve, and the multiple protrusions are arranged in a ring on the outer wall of the movable sleeve.

[0017] Compared with the prior art, this utility model provides a valve-controlled ultrasonic water meter, which has the following beneficial effects:

[0018] 1. This valve-controlled ultrasonic water meter, through the cooperation of the connecting pipe, the first sealing ring, the locking sleeve and the screw head, can fix and seal the water inlet connection between the control valve and the ultrasonic meter body, thereby reducing the possibility of water leakage.

[0019] 2. This valve-controlled ultrasonic water meter, through the second sealing ring, can also form a double seal with the first sealing ring, further improving the sealing performance at the connection between the control valve and the ultrasonic meter body. In addition, the second sealing ring with a petal-shaped corrugated pattern can also increase its contact area with the locking sleeve, which means that there is a larger surface at the seal to prevent fluid from passing through, thereby avoiding water leakage, preventing water waste, and ensuring the accuracy of water flow measurement by the water meter.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model solves the problem that existing valve-controlled ultrasonic water meters are prone to poor sealing and leakage after long-term use due to material aging or design defects, which affects the accuracy of metering and leads to water waste.

Therefore, they should not be construed as limitations on this utility model.

[0028] Example:

[0029] Reference Figures 1-4 This utility model provides a valve-controlled ultrasonic water meter, including an ultrasonic meter body 1 and a control valve 2 installed on the ultrasonic meter body 1. The ultrasonic meter body 1 can be a Xintian Technology LXHY series or a Maituo Instrument MT-800 series. The control valve 2 is an electric ball valve, an electric butterfly valve, or an electric regulating valve, which facilitates the management of the water meter, enables remote opening and closing operations, and controls the flow of water. It also includes a first sealing ring 4 disposed on the ultrasonic meter body 1. A connecting pipe 3 is fixedly connected to the water inlet end of the ultrasonic meter body 1. The first sealing ring 4 is sleeved on the connecting pipe 3. A groove 41 is provided on the connecting pipe 3, and the first sealing ring 4 is fixedly connected in the groove 41, which improves the stability of the first sealing ring 4 and makes it less likely to fall off. When the connecting pipe 3 and... When the interface of control valve 2 is plugged in, the first sealing ring 4 undergoes elastic deformation and abuts against the inner wall of the interface of control valve 2. The port of the connecting pipe 3 is rounded to improve the assembly efficiency of the interface between the connecting pipe 3 and control valve 2. The second sealing ring 5 is fixedly connected to the interface of control valve 2. The edge of the second sealing ring 5 is petal-shaped and forms an annular corrugated structure. Both the second sealing ring 5 and the first sealing ring 4 are made of fluororubber, which has excellent heat resistance and chemical stability and is not easy to age and corrode, thus ensuring the sealing reliability of the water meter inlet connection. The connecting pipe 3 is provided with fasteners, which are used to fix control valve 2 and connecting pipe 3, so that the second sealing ring 5 undergoes elastic deformation and seals the connection between control valve 2 and connecting pipe 3.

[0030] Specifically, during use, the connection pipe 3, the first sealing ring 4, the second sealing ring 5, and the fasteners work together to double seal the water inlet connection between the control valve 2 and the ultrasonic meter body 1, thereby ensuring the sealing performance of the connection between the control valve 2 and the ultrasonic meter body 1. Furthermore, the second sealing ring 5, which adopts a petal-shaped corrugated pattern, can increase its contact area, meaning that there is a larger surface area at the seal to prevent fluid from passing through, thereby avoiding water leakage, preventing water waste, and ensuring the accuracy of water meter measurement.

[0031] The fasteners in the ultrasonic water meter include a locking sleeve 6 fixedly sleeved on the connecting pipe 3 and a movable sleeve 7 movably sleeved on the control valve 2. The locking sleeve 6 and the movable sleeve 7 are connected by a threaded component, which includes a screw head 8 fixedly connected to the movable sleeve 7. The locking sleeve 6 has a screw groove 81, and the screw head 8 is threaded into the screw groove 81. When the connecting pipe 3 is inserted into the interface of the control valve 2, the second sealing ring 5 abuts against the surface of the locking sleeve 6.

[0032] Specifically, during use, the locking sleeve 6, the movable sleeve 7, the screw head 8, and the screw groove 81 work together to fix the connecting pipe 3 and the control valve 2, preventing the connecting pipe 3 from coming loose from the interface of the control valve 2, improving the assembly stability of the control valve 2 and the ultrasonic meter body 1, and also providing extrusion pressure to the second sealing ring 5, causing it to undergo elastic deformation and fit tightly against the surface of the locking sleeve 6, thereby improving the sealing performance at the connection between the control valve 2 and the ultrasonic meter body 1.

[0033] The diameter of the connecting pipe 3 is smaller than the inner diameter of the control valve 2 interface, and the outer diameter of the first sealing ring 4 is larger than the inner diameter of the control valve 2 interface.

[0034] Specifically, by making the diameter of the connecting pipe 3 slightly smaller than the inner diameter of the control valve 2 interface, the control valve 2 and the connecting pipe 3 can be easily plugged and assembled, making the connection smoother. Furthermore, by making the outer diameter of the first sealing ring 4 slightly larger than the inner diameter of the control valve 2 interface, the first sealing ring 4 can fit tightly with the control valve 2, achieving a close fit between the first sealing ring 4 and the inner wall of the control valve 2 interface.

[0035] The aforementioned movable sleeve 7 is fixedly connected with a plurality of protruding strips 9, and the plurality of protruding strips 9 are arranged in a ring on the outer wall of the movable sleeve 7. The number of protruding strips 9 is 12 to 18, and preferably 15 in this water meter.

[0036] Specifically, by setting the convex strip 9, the friction on the surface of the movable sleeve 7 can be increased, so that the movable sleeve 7 can be rotated by applying force.

[0037] Working principle: When this valve-controlled ultrasonic water meter is in use, when the control valve 2 is connected to the ultrasonic meter body 1, the connecting pipe 3 is inserted into the interface of the control valve 2. At the same time, the first sealing ring 4 will be squeezed and produce elastic deformation, which will tightly adhere to the inner wall of the interface of the control valve 2, thereby achieving the first seal.

[0038] Furthermore, during connection, the surfaces of the second sealing ring 5 and the locking sleeve 6 abut against each other. Then, the movable sleeve 7 slides towards the locking sleeve 6 and rotates to make the screw head 8 threaded into the screw groove 81. This can lock and fix the connecting pipe 3 and the control valve 2, improve the assembly stability of the control valve 2 and the ultrasonic meter body 1, and also provide extrusion force to the second sealing ring 5, causing it to undergo elastic deformation and fit tightly against the surface of the locking sleeve 6, thereby achieving a second seal. The petal-shaped corrugated pattern of the second sealing ring 5 can increase the contact area between the second sealing ring 5 and the locking sleeve 6, meaning that there is a larger surface area at the seal to prevent fluid from passing through, thereby avoiding water leakage.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
