Embodiment Construction

[0028] figure 1 A valve 1 for a radiator or another heat exchanger in a heating or cooling system is schematically shown. The valve 1 has a housing 2 . Housing 2 comprises an inlet 3 and an outlet 4 . The inlet 3 and outlet 4 may also be arranged at another angle than the one shown. Regardless, the housing can have different geometries, such as angled, rectilinear, right-angled, T-shaped, etc. geometries.

[0029] A valve seat arrangement with a first valve seat 5 and a second valve seat 6 is positioned between the inlet 3 and the outlet 4 .

[0030] The valve element 7 is arranged between the two valve seats 5 , 6 . The valve element 7 is mounted at the valve stem 8 . The valve stem 8 is loaded by a spring 9 . The valve stem 8 comprises an end 10 protruding out of the housing 2 so that the actuator A can act on the valve stem 8 in the opposite direction to the spring 9 . Actuator A controls the position of valve element 7 . The actuator A performs the function of dete...

Abstract

Provided is a valve (1), in particular a radiator valve, comprising a housing (2), an inlet (3), an outlet (4), a valve seat between the inlet (3) and the outlet (4) means (5, 6), and a valve element (7) movable relative to said valve seat means (5, 6), wherein detection means (A) are arranged for detecting the position of said valve element (7). In this valve, the closing point should be found in a simple way. To this end, said valve seat arrangement (5, 6) comprises at least a first valve seat (5) and a second valve seat (6), said first valve seat (5) and said second valve seat (6) At least one of them forms a reference valve seat, said valve element (7) being movable to contact at least said reference valve seat.

Description

technical field [0001] The invention relates to a valve, in particular a radiator valve, comprising a housing, an inlet, an outlet, seat means between said inlet and said outlet, and a valve movable relative to said seat means An element, wherein detection means are provided for detecting the position of said valve element. Background technique [0002] This valve is known from DE3900866C2. The valve element is driven via a gear arrangement by a motor acting on the valve element. A rotating disk is arranged between the gear arrangement and the valve element. The disk includes markings so that the rotational position of the disk can be detected. The rotational position can be used to calculate the position of the valve element. [0003] Another valve of the aforementioned kind is known from DE19742098C2. The valve element is driven by an electric motor. In order to detect the closing point of the valve element, the motor is controlled to a constant rotational speed. Th...
