FIELD: tool-making industry, in particular, direct action temperature controllers, possible use for automatic air temperature control in rooms fitted out with heating devices. ^ SUBSTANCE: temperature controller contains temperature sensor, mounted in a case, connected through a rod to a valve installed in heat carrier feeding pipeline and containing return spring, valve control unit, provided with two bushings, mounted coaxially and concentrically to the rod, inside bushings return spring is mounted together with supporting washer fastened on the rod. Temperature sensor case is connected to heat carrier feeding pipeline through replaceable layer. Valve holding device is mounted on the end of the rod, above the pass aperture of heat carrier pipeline wall. Locking device of the valve is made in form of bushing, supporting washer, packing layer and screw spring. Supporting washer and packing layer are rigidly held on external side of the bushing, and screw spring is held by one end in internal hollow of the bushing, while its outer end is held on the end of the rod. ^ EFFECT: decreased hydraulic resistance coefficient of the controller. ^ 3 dwg |
