How is the tooling for designing the valve seat and sealing ring of a triple-eccentric butterfly valve designed? Are there any pictures or diagrams, oh my god:'(
Hehe, that’s probably the core technology of that company’s products; take a look in the market and see how many companies are able to produce such valves.
It’s just three eccentricities; talking about core technology is a bit much! ! \"Butterfly Valve Design Technology and Atlas\", compiled by Zhu Peiyuan – this book contains detailed drawings! The original poster can add me on QQ at 1264186833; I’ll take pictures and send them to you
I’ve seen quite a lot of discussions about three-eccentric butterfly valves lately. Has the use of this type of valve become more common?
It is mainly used in the air separation industry for switching valves; it is less common in other areas.
The usage of triple-eccentric valves is quite widespread; they are employed in air separation, synthesis, purification, and desulfurization processes. Large-diameter butterfly valves are used frequently, as they offer a price advantage over ball valves, and moreover, butterfly valves possess regulation capabilities. However, the level of three-eccentric hard-sealing technology in China is still uneven; few products meet API598 standards, and there are virtually none that offer dual sealing for high temperature and high pressure conditions
This is the development direction for domestic front-end companies

At the moment, the largest diameter I can achieve here is 3 meters
Impressive, thumbs up! You can show it
