TEMPERATURE CONTROL Russian patent published in 2010 - IPC F16K27/10 F24D19/10 

FIELD: heating.

SUBSTANCE: temperature control includes housing with ball-shaped middle part, inlet and outlet connection pipes. On opposite end from inlet connection pipe there is a threaded connection pipe. Temperature control valve is screwed into it. The above connection pipes are interconnected with inner cavity of ball-shaped middle part. Inner surface of inlet connection pipe is provided with cylindrical section of large diametre and cylindrical section of small diametre. The above sections are located in serried from the centre of ball-shaped middle part of the housing to the end of inlet connection pipe. Between ball-shaped middle part and cylindrical section of large diametre of inlet connection pipe there is conical surface converging towards the end of inlet connection pipe. Between cylindrical section of large diametre of inlet connection pipe and cylindrical section of small diametre of inlet connection pipe there is smaller conical surface converging towards the end of inlet connection pipe. Ball-shaped middle part of the housing, inlet connection pipe and threaded bar form one integral pressed part made from welded material. Outlet connection pipe is put into ball-shaped middle part of the housing and attached to that part of the housing by welding. Temperature control valve has working conical surfaces. They are located in series from one valve end towards its middle part. Conical surface of the valve are located so that they can interact with the appropriate conical surfaces of the housing.

EFFECT: improving operating reliability of the housing.
