摘要： A valve housing has an upper and a lower elongated shell each having opposite end portions and a wider intermediate portion with the intermediate portion of the upper shell also being provided with an opening. Lateral edge faces are provided on the respective shells extending longitudinally thereof and abutting and welded to one another in a plane of separation. A first transverse rib of the the lower shell is arcuately curved intermediate one of the end portions and the opening and has an upwardly directed surface located in the plane of separation. A second transverse rib interiorly of the upper shell is arcuately curved from the first rib towards the opposite end portion and around the opening and has a downwardly directed face which merges with the respective lateral edge faces of the upper shell. A support ring is embraced by and welded to the ribs and has an other downwardly directed face partly overlying and welded to the upwardly directed surface with both of these faces having general planes inclined upwardly from the region of the upper surface and the plane of separation to a level above the latter. The transverse width of the edge faces is at least substantially uniform over the elongation of the shells and the respective inner margins of the edge faces are exposed and offset with reference to the support ring below the general planes of the faces so as to facilitate free access and passage of a welding beam to said edge faces and to the interface defined by the upwardly directed surface of the first rib and the other downwardly directed face of the support ring.
