초록

A horizontal check valve has a swinging clapper (16) eccentric with a tapered valve seat (14) and carrying a floating ring seal. There is clearance between the clapper (16) and the passage wall at the bottom so that reverse flow urges the ring seal into the taper. The clapper (16) abuts an abutment surface (15) formed by the valve body (10) around the valve seat so that the hydrostatic forces exerted on the clapper (16) by the reverse fluid flow are reacted by the abutment surface and not by the tapered seat (14).

A check valve comprising a housing which forms a through passage which is to be connected into a fluid pipeline when the valve is in use, the housing including an annular valve seat which extends around the passage and tapers towards the upstream end of the passage in the context of the normal direction of flow through the passage, and an obturating member cooperable with the valve seat to close the through passage and displacable from the valve seat to allow fluid flow through the through passage, the obturating member carrying an annular seal which eff...
