Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing equipment, and particularly relates to a magnetic sealing gasket for the inner valve body of a water meter. Background Art
[0002] In fluid transmission systems such as water supply, heat supply, and gas supply, water meters are important metering devices. To ensure the accurate metering and sealing performance of water meters, the valve body sealing gasket is one of the key components. Traditional valve body sealing gaskets are usually made of materials such as rubber or polytetrafluoroethylene, but these materials have problems such as easy aging, easy wear, intolerance to high temperature, and intolerance to corrosion, which easily cause leakage and metering errors of water meters. To solve these problems, magnetic sealing gaskets are introduced into the valve body of water meters. The magnetic sealing gasket utilizes the magnetic force of magnetic materials to achieve a tight sealing effect, improving the sealing performance and metering accuracy of water meters. At the same time, due to the special properties of magnetic materials, the magnetic sealing gasket also has certain corrosion resistance and high temperature resistance, and can adapt to various complex water quality conditions and environmental temperatures. However, the sealing effect of the existing magnetic sealing gaskets for the inner valve body of water meters needs to be improved. Content of the Utility Model
