Embodiment Construction

[0030] The valve 1 designed as a heater valve has a valve housing 2 . The valve casing 2 has a first channel 3 and a second channel 4 . A valve seat 5 is arranged between the first channel 3 and the second channel 4 . The valve seat 5 bears against the end face 6 of the insert 7 , which is screwed into the valve housing 2 , with a metal seal, not shown in detail, acting as an interlayer. To this end, the insert 7 has an external thread 8 as a first fastening geometry, which meshes with an internal thread 9 in the valve housing 2 .

[0031] The actuating device housing 10 is screwed into the insert part 7 . The actuating device housing 10 has a valve element 11 fastened to a valve stem 12 which is loaded by an opening spring 13 in the direction away from the valve seat 5 . When the valve rod 12 and thus the valve part 11 are to move in the opposite direction, pressure is exerted on the actuating pin 14 , which extends through the stuffing box 15 . In order to actuate the ac...

Abstract

A valve (1) is provided, in particular a radiator valve, with a valve housing (2), which has a first channel (3), a second channel (4) and a path in between with a valve seat (5), and with a valve element (11) which is movable in the direction of the valve seat (5) and in an opposite direction and is held in an actuating housing (10) which is connected to the valve housing (2), wherein the first channel (3) is connected to a side of the valve seat (5) which faces away from the valve element. It would be desirable to be able to eliminate installation errors in a simple manner. For this purpose, it is provided that an insert (7) is arranged in the valve housing (2), said insert interrupting the path and having an auxiliary valve seat (20), the side of which facing the valve element (11) is connected to a first space (21) which is connected to the first channel (3) through the valve seat (5), and the side of which facing away from the valve element (11) is connected to a second space (22) which is connected to the second channel (4).

Description

technical field [0001] The invention relates to a valve, especially a heater valve, which comprises a valve housing and a valve member, the valve housing has a first passage, a second passage and a path with a valve seat between the two passages, the valve member can move towards the valve The seat moves in one direction onto the valve seat and in the opposite direction and is secured in an actuator housing connected to the valve housing, wherein the first channel is connected to the side of the valve seat facing away from the valve element. Furthermore, the invention relates to an insert for such a valve. Background technique [0002] A valve of this type is known, for example, from DE 1139707 B2. As the valve member moves closer to the valve seat, the valve member restricts flow through the valve. When the valve part moves away from the valve seat, the valve part releases a larger flow cross section. [0003] In such valves, the valve member should pass the valve seat a...
