The first type is a bolt type valve cover, which is connected by concave and convex surfaces and uses stainless steel strips and flexible graphite wrapped gaskets. Ring connections can also be used as needed. The second type is a welded valve cover, which is sealed by threads and welded directly. Rigid welding can also be used as needed. The third type is a self sealing valve cover, which is connected to the self sealing valve cover by threads.
