VALVE BODY WITH RING STEM GUIDE Russian patent published in 2017 - IPC F16K27/06 

FIELD: machine building.

SUBSTANCE: valve includes a housing having a central portion and two connecting pipe, which project from the central portion. Inside the central part of the valve body is a bore. The valve body is arranged at the valve seat and the valve is connected with the spindle, a guide sleeve located on the valve spindle. The valve body is made from a tubular plastic deformation method. The tubular element is performed with the inner edge of the cutout. Through the notch obtained by plastic deformation of the ring member in place cutout. Resulting in the formation of the spindle guide bushing. The notch has an edge whose shape allows rotation in the direction of the edge from the central portion of the valve body after the formation of the annular member. Thus, the end face forming operate spindle guide sleeve. Further, the cutout comprises at least one protrusion that before carrying out plastic deformation is in the plane of the recess.

EFFECT: reducing the number of operations of cut and cutting material before mounting the valve seat and the valve body, which is set before the final finish of the valve body.
