Embodiment Construction

[0023] FIG. 1 shows a radiator-mounted valve 1 which has a housing 2 in which a valve stem 3 is arranged, on which a valve plug 4 is mounted.

[0024] The valve core 4 cooperates with a valve seat 5 formed on a connecting piece 6 .

[0025] The spool 4 is pushed up from the valve seat 5 by means of an opening spring 7 . An operating rod 9 passing through the plug sleeve 8 acts in the closing direction, which operating rod can be pressed more or less deeply into the housing 2 by an operating device not shown in detail, such as a thermostatically operated bonnet, so that The gap between the valve plug 4 and the valve seat 5 is more or less closed.

[0026] The housing 2 has an outlet connection 11 which may have a fastening thread 12 .

[0027] The connecting piece 6 is inserted into a pipe connection 10, which is indicated by dashed lines. The connecting piece 6 has a through-opening 13 which leads from an inlet 14 to the valve seat 5 .

[0028] Alternatively, the connectin...

Abstract

The invention relates to a radiator built-in valve (1) comprising a connecting element (6), which has a body (19) and a sealing zone for sealing a contact area with a supply or discharge connection (10, 15). The aim of the invention is to increase the versatility of the built-in valve during its use. To this end, the sealing area has both a radially inward working first seal (16) as well as a radially outward working second seal (18).

Description

technical field [0001] The present invention relates to a radiator-inlet valve having a connecting piece having a main body and a sealing area for sealing the contact area with an inlet or outlet fitting. Background technique [0002] Such a radiator insert valve is known from DE 3600130 A1. Here, the connection piece is inserted into an inlet or outlet fitting. An O-ring is disposed between the connection piece and the fitting and prevents fluid from flowing away through the contact area between the connection piece and the fitting. [0003] Another possibility is disclosed in DE 20020024U1. There, the connecting piece is pushed onto the pipe connection from the outside. Furthermore, an O-ring forming a seal is arranged in the inner groove. In this way, the contact area between the pipe connection and the connecting piece can also be sealed. [0004] Under normal conditions, it is not visible from the outside what type of seal has been chosen in the radiator valve. If...
