A valve device

Abstract

This application provides a valve device, including a valve body having a valve cavity; an adapter portion fixedly connected to or integrally formed with the outer wall of the valve body; an interface portion having an interface channel communicating with the valve cavity; the interface portion being made of a different material than the valve body, with the interface portion being made of a material with lower strength than the valve body; and a connector detachably connecting the adapter portion and the interface portion. In this application, the interface portion being made of a different material than the valve body, with the interface portion being made of a material with lower strength than the valve body, makes the interface portion easier to machine, reducing costs; the adapter portion and the interface portion are detachably connected, allowing for the replacement of either the valve body or the interface portion individually if defects are found during inspection, eliminating the need for complete scrapping and saving costs; different interface portions can also be replaced according to usage needs, making the valve device more versatile; because the interface portion is made of a different material than the valve body, the interface portion is detachably connected to the valve body via the adapter, avoiding welding between the interface portion and the valve body and avoiding the risks associated with welding dissimilar metals.
