Description

Technical Field

[0001] This utility model belongs to the field of electronic water meter technology, specifically relating to a sealing connection structure for the meter head of an electronic water meter. Background Technology

[0002] Water resources are an indispensable resource for human life and social development. As a key measuring instrument for measuring water usage, water meters play a vital role in water resource management, water supply system operation, and water fee measurement. They not only provide water supply departments with accurate water usage data to rationally plan water resource allocation and water supply facility construction, but also provide users with clear water usage measurement basis, promoting users' awareness of water conservation. With social development and the acceleration of urbanization, the requirements for the accuracy, reliability, and stability of water meters are becoming increasingly higher.

[0003] Existing electronic water meters mostly use sealing rings to seal the connection between the outer casing and the meter head. When exposed to changes in external temperature, the sealing rings expand or contract with the temperature change, which affects the connection between the outer casing and the meter head. This can easily lead to moisture entering the meter head and corroding its internal electronic components, thus affecting the use of the water meter. Therefore, a new sealing connection structure for the meter head of electronic water meters is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing connection structure for the meter head of an electronic water meter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a meter head sealing connection structure for an electronic water meter, comprising an electronic water meter body, a sealing component provided in a groove on the inner wall of the electronic water meter body, a first drying plate provided at the top and bottom of the sealing component, a meter head provided on the inner side of the sealing component, a rubber sealing ring provided on the outer side of the bottom of the meter head, a sealing groove provided on the outer side of the rubber sealing ring, the sealing component including a spring washer, an elastic metal sheet provided on the inner side of the spring washer, a silicone sealing ring provided on the inner side of the elastic metal sheet, and a sealing protrusion provided on the inner side of the silicone sealing ring.

[0006] In a preferred embodiment, the sealing protrusion is made of silicone and is adapted to and connected to the sealing groove.

[0007] In a preferred embodiment, the interior of the electronic water meter body is connected to the meter head via threads, and a connecting pipe is connected through the bottom of the meter head.

[0008] In a preferred embodiment, the rubber sealing ring is made of rubber, the silicone sealing ring is made of silicone, and the rubber sealing ring and the silicone sealing ring are in contact and connected.

[0009] In a preferred embodiment, a second drying plate is placed on top of the meter head, and a top cover is provided on top of the second drying plate. The bottom of the top cover is connected to the electronic water meter body by threads.

[0010] In a preferred embodiment, the top of the top cover is spherical, the bottom of the electronic water meter body is spherical, and the second drying plate is adapted between the bottom of the top cover and the top of the meter head.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention provides continuous pressure and adaptability for sealing through the use of spring washers and elastic metal sheets. The spring washers generate a certain elastic restoring force, ensuring that the sealing assembly remains tightly fitted to the meter head and the main body of the electronic water meter. The elastic metal sheets enhance the strength and stability of the sealing structure, maintaining the reliability of the seal under temperature changes or external forces. When the sealing material expands or contracts, the elastic force of the spring washers can adjust the sealing pressure, ensuring that the sealing assembly remains tightly fitted and preventing seal failure due to thermal expansion and contraction. The matching design of the sealing groove and sealing protrusion makes the seal more precise and tight. The sealing protrusion can be embedded in the sealing groove, increasing the contact area and sealing performance, thereby effectively preventing water penetration.

[0013] This invention effectively absorbs moisture inside the water meter through the configuration of a first drying plate and a second drying plate. The first drying plate, located at the top and bottom of the sealing assembly, prevents external moisture from entering the sealing area and absorbs any small amount of moisture that may have already seeped into the vicinity of the sealing assembly. The second drying plate, placed between the top of the meter head and the top cover, further absorbs moisture inside the meter head, keeping the internal environment of the meter head dry. The spherical design of the top cover and the bottom of the electronic water meter body increases the stability of the structure. The spherical structure can disperse external forces and improve the water meter's impact and pressure resistance. The combination of elastic metal sheets and spring pads can buffer external vibrations and impacts, allowing the sealing assembly to maintain a stable sealing effect even in vibrating environments.
