one. A gate valve structure for use in mains carrying a fluid, claimed gate valve structure comprising: a valve casing possessing a by way of-bore with spaced axially aligned ports and a valve chamber intermediate the ports and delivering unobstructed interaction among the ports, claimed valve chamber becoming outlined by a curved base wall offering a continuation of The underside of the by way of-bore, oppositely disposed planar facet walls diverging upwardly from explained curved base wall at a predetermined bundled angle, and an higher open up stop frequently rectangular in crosssection parallel for the axis with the through-bore, explained higher open conclude remaining defined by higher parts of said divergent aspect partitions and by divergent oppositely disposed walls extending typically transverse with the through-bore, mentioned base wall, divergent facet walls and at the least one of stated transversely extending partitions furnishing a steady surface area defining a valve seat; and also a generally flat valve gate member movable throughout the higher open up conclude of stated valve chamber into a shut posture blocking stated by way of-bore, reported gate member having a covering on the exterior thereof crafted from a deformable material, stated gate member getting a configuration in elevation significantly comparable to the crosssectional configuration of stated valve chamber transverse of mentioned by-bore and aquiring a seating surface provided by its covering complementary to the continual area defining said valve seat in mentioned casing, explained seating floor together with a minimum of a bead-like rib over a percentage of gate member''s periphery aquiring a curved base portion and diverging side portions, the diverging aspect parts of claimed bead-like rib aquiring a predetermined included angle somewhat under explained predetermined involved angle of your facet walls of stated valve chamber, whereby Make contact with happens to begin with involving the diverging facet parts of reported bead-like rib and the planar side walls of stated chamber to make certain ample compression therebetween no less than at some time suitable sealing is attained concerning the curved bottom portion of said bead-like rib and also the curved bottom wall of stated chamber.
