Combined control and regulating valve for liquids or gases

A valve for measuring and controlling at least one of temperature and pressure in a fluid medium channel comprising:

• a valve housing (2) defining said fluid medium channel therein and having a partition wall (5) dividing said fluid medium channel into an inlet (3) and an outlet (4);
• a valve bore (118) in said housing having a valve spindle (8, 15) extending therethrough in sealed engagement therewith, a valve body (7, 25) attached to an inner end of said spindle (8, 15), an outer diameter of said valve body (7, 25) being slightly smaller than an inner diameter of said valve bore (118), thereby defining an annular narrow gap (112) between an inner peripheral surface of said valve bore and an outer peripheral surface of said valve body;
• a valve opening passing through said partition wall (5) connecting said inlet to said outlet and having an edge located in said partition wall (5) defining a valve seat (6) for cooperation with said valve body (7, 25);
• a first passage (31) extending into said housing and having a first passage extension (30) extending said first passage (31) into communication with said outlet (4) on a side of said valve body (7, 25) remote from said valve seat (6);
• and
• a first measuring nipple (74) sealingly received in said first passage (31), for insertion of a measuring probe, through said first measuring nipple and into said first passage for measuring at least one of temperature and pressure at a location in said first passage (31), said first passage (31) being in communication with said outlet (4) via said first passage extension (30) and said narrow gap (112);
• wherein said valve body (7, 25) and said valve bore (118) are sized to provide said narrow gap (112) with a gap width sufficient to permit equalization of pressure of the fluid medium on both sides of said gap, yet narrow enough to prevent turbulence created in the region of said valve seat (6) from passing through said narrow gap into said first passage (31), to ensure accurate measuring results.
