Description

Technical Field

[0001] The utility model relates to the technical field of gas wall-mounted boilers, and particularly relates to a plastic integrated waterway component for a gas wall-mounted boiler. Background Technique

[0002] There are many limitations in the design and installation of traditional gas wall-mounted boiler water systems. First of all, due to the extensive use of metal pipes and fittings, the entire water system is not only heavy, but also the installation process is complex. Professional technicians need to spend a long time for precise threaded docking, which not only increases the installation cost, but also limits the user's ability to install independently. Secondly, the use of metal materials may also cause rusting of the system after long-term operation, increasing the risk of leakage, and thus affecting the safety and service life of the system. Therefore, we have proposed a plastic integrated waterway component for a gas wall-mounted boiler. Content of the Utility Model
