PURPOSE:To simplify structure, and to decrease cost, by integrally incorporating a discharge-regulating valve and a by-path valve into a tank of a radiator for heating, and by forming the discharge-regulating valve in a laminar valve perpendicular to the flowing direction of hot water. CONSTITUTION:Radiant tubes 12 are mounted between a hot-water inlet tank 1 and an outlet tank 15, the tank 1 is divided into two chambers by means of a valve seat plate 2 and an upper cover is used as a valve housing 1a. A through hole 2a is installed to the plate 2, and a laminar, fan-shaped discharge-ragulating valve body 4 is housed in a semicircular valve chamber 3 in a revolution-free form and in a shape that is opposed to the through hole 2a. Holes 4b for continuously changing flux by the angles of revolution are made to the valve body 4. A passage 19 is opened to the valve chamber 3, a by-path valve 22 opening when pressure rises is mounted on the way of the passage 19 and a by-path passage is made up through a pipe 12' from a hole 2e. |
