Abstract

PURPOSE:To prevent packing from damaging due to overtightening in installation by providing a pipe-like circumscribed duct contacting to piping flanges on both sides in installation, on outside of a valve box and fixing upper and lower bearings for the valve shaft to the circumscribed duct. CONSTITUTION:A valve body 20 im arranged in a valve box 10 cylindrical in shape. On the outer side of the valve box 10, is arranged a pipe-like circumscribed duct 30 contacting to piping flanges 40, 40' on both end faces in installation. Upper and lower bearings 70, 70' for the valve shaft are fixed to the circumscribed duct 30. Packings 80, 80' are mounted between the valve box 10 and the circumscribed duct 30 and between the valve box 10 and the piping flanges 40, 40'. According to this arrangement, as it is able to catch the tightening force on the piping flanges 40, 40' with the circumscribed duct 30, packings make seal on keeping elasticity continuously, so damage on the same is prevented, too.
