ErfindungGefahr gestattet. 



   Es ist aber auch möglich, die Abdichtung zwischen der Schliesskörperfläche   3"des Schliesskörpers   3 und der inneren Fläche   16'des   Gehäuseoberteiles 16 ohne Dazwischenlegung eines Dichtungsstückes zu erzielen. In diesem Fall müssen aber die   Berührungsflächen   vollständig bearbeitet sein. 



   Andere Varianten bestehen in der verschiedenen Formgebung des Loches 6 des Schliesskörpers, welches Loch z. B. sechseckig anstatt viereckig ist, sowie in der Anordnung eines einzigen Dichtungsringes 9 in der Auskehlung 11 der Spindel 7. 



   Es ist ebenfalls vorgesehen, dass das   erfindungsgemässe Ventil   als Mengenregler oder zu jedem andern beliebigen Zweck anwendbar ist.

Invention Danger Allowed.



   However, it is also possible to achieve the seal between the closing body surface 3 ″ of the closing body 3 and the inner surface 16 ′ of the upper housing part 16 without interposing a sealing piece. In this case, however, the contact surfaces must be completely machined.



   Other variants consist in the different shape of the hole 6 of the closing body, which hole z. B. is hexagonal instead of square, and in the arrangement of a single sealing ring 9 in the groove 11 of the spindle 7.



   It is also provided that the valve according to the invention can be used as a flow regulator or for any other purpose.

Claims

PATENT CLAIM: Valve, in particular for water and steam heating and for water pipes, e.g. B. as a volume regulating organ, with a directly externally threaded closing body which can be screwed into a valve body provided with a corresponding internal thread by means of a spindle, which can be removed during operation, the closing body maintaining its position relative to the valve body and the spindle with a retaining seal is provided, according to patent no.

225487, characterized in that in the open position of the valve the surface (3 ") of the closing body (3) remote from the valve seat is supported against a flange-like surface (16 ') of an upper housing part (16) attached to the valve body and protruding inward in the radial direction A seal (15) is inserted between the upper housing part (16) and the valve body (1) and extends in the radial direction, in particular up to the spindle (7), so that it serves as a stop for the closing body surface (3 ") facing away from the valve seat and an additional seal is created for sealing between the valve body fine thread (5) and valve body (1).
