FIELD: machine building. ^ SUBSTANCE: procedure for fabrication of case of valve consists in making pipe (210) of required length, and in forming first and second ends of said pipe. The first end is made with an orifice and flange. The second end is designed for connection to the second part of the valve case. Second part (220) has the first end with a zone of expansion, a channel and the second end. The first end of the second part has a flange and an orifice coming to the zone of expansion. The configuration of the channel facilitates regulation of the flow of liquid medium running through it. The second end adjoins the said channel and has a cut out section. Configuration of the cut out section ensures its conjugation with the section of the second end of the pipe. Connection of the second end of the pipe to the second end of the second part is made together with forming at least a section of the valve case. There is disclosed the valve case made according to the above described procedure. ^ EFFECT: reduced expenditures at fabrication of valve case. ^ 2 cl, 4 dwg |
