Problems solved by technology
[0002] Most of the check valves currently used in air conditioners are composed of a tubular valve body, a valve seat, a valve core and a fixed bracket. It must be vertically upward during use and installation, and a slight deviation may cause gas leakage, while the ball or cone valve core is easy to wear the sealing contact surface after a period of use, reducing the airtightness of the valve core
In addition, because the valve seat and the valve body are fixed by tin welding, the solder joints are easy to melt when exposed to high temperature, and the check valve needs electric welding during installation, which generates high temperature, so if the welding time is longer, it is easy to Melting due to heat transfer to solder joints, resulting in gas leakage hazards

The invention relates to a one-way valve for an air conditioner. The one-way valve comprises a tubular valve body, a valve base positioned in the valve body, a valve element and a fixed bracket; the valve base and the valve body are combined; the valve base is provided with a groove in a contacted section with the valve element, and a magnet is embedded in the groove; an annular groove is formed in the side wall of the valve base; and the valve element is a circular steel piece with a triangular edge. The one-way valve is convenient for installation and use, and can be effectively opened and closed in one direction without being influenced by high temperature generated in installation.
Description
technical field [0001] The invention relates to a one-way valve, in particular to a one-way valve for an air conditioner. Background technique [0002] Most of the check valves currently used in air conditioners are composed of a tubular valve body, a valve seat, a valve core and a fixed bracket. It must be vertically upward during use and installation, and a slight deviation may cause gas leakage, and the ball or cone valve core will easily wear the sealing contact surface after a period of use, reducing the airtightness of the valve core. In addition, because the valve seat and the valve body are fixed by tin welding, the solder joints are easy to melt when exposed to high temperature, and the check valve needs electric welding during installation, which generates high temperature, so if the welding time is longer, it is easy to The heat is transferred to the tin soldering point to cause melting, which brings about the hidden danger of gas leakage.
