Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a water meter that can be quickly connected. Background Art

[0002] Currently, all small-diameter water meters on the market utilize threaded connections. In the early days, when water meter cases were made of cast iron or copper, and when manual installation efficiency and quality requirements were low, the problems associated with traditional threaded connections were less pronounced. However, with the introduction of thin-walled welded stainless steel meter cases, compatibility issues with stainless steel pipe nuts have become increasingly prominent. These include misaligned engagement leading to meter leakage and difficulty removing the nuts, electrochemical corrosion from the same materials preventing removal, and damage to the electrolytic plating, which can lead to rust. Large threads require auxiliary tools such as large wrenches, making them difficult to use within the confined space of a water meter installation. Furthermore, tightening the pipe nut can cause the sealing gasket to rotate with it, making it susceptible to displacement and loss of sealing effectiveness. Utility Model Content

The arc-shaped flanges 3-2 are arranged on both sides of the upper and lower planes of the sealing gasket 3, and the cross-section of the arc-shaped flanges 3-2 is arc-shaped. At the same time, although the arc-shaped flanges 3-2 are arranged near the outer circle of the sealing gasket 3, the arc-shaped flanges 3-2 do not directly contact the outer circle of the sealing gasket 3.

[0068] In the above technical solution, the arc-shaped flange 3-2 can make the sealing effect better, and the rectangular flange 3-2 can cooperate with the water meter housing 1 for positioning to prevent the sealing gasket 3 from sliding.
