Valve for the control of fluids
A valve for controlling fluids, which has a plurality of components that are disposed in succession in the axial direction of the valve. On at least one of the components, a male thread is embodied in order to enter into engagement with a female thread of a lock nut. The lock nut serves to brace the components of the valve. A sealing element is disposed between the female thread of the lock nut and the male thread of the component.
1. A valve for controlling fluids, the valve comprising
a plurality of components ( 2 , 3 , 4 , 5 ) disposed in succession in the axial direction (X—X) of the valve,
a male thread ( 9 ) formed on at least one of said components ( 2 ),
a lock nut ( 6 ) having a female thread ( 10 ) which in the mounted state of the valve is in engagement with the male thread ( 9 ) of at least one component ( 2 ), in order to brace the components ( 2 , 3 , 4 , 5 ) against one another, and
a sealing element ( 8 ; 11 ; 17 ) disposed between the female thread ( 10 ) of the locknut ( 6 ) and the male thread ( 9 ) of the component ( 2 ),
wherein the sealing element is embodied as a plastic ring ( 11 ) or as a shrink-fit hose ( 17 ), and
wherein the plastic ring ( 11 ) comprises at least one protruding region ( 13 ) for positional fixation of the plastic ring.
2. The valve of claim 1 , wherein the lock nut 6 further comprises a flanged-over portion ( 16 ) for fixing the plastic ring ( 11 ).
3. A valve for controlling fluids, the valve comprising
a plurality of components ( 2 , 3 , 4 , 5 ) disposed in succession in the axial direction (X—X) of the valve,
a male thread ( 9 ) formed on at least one of said components ( 2 ),
a lock nut ( 6 ) having a female thread ( 10 ) which in the mounted state of the valve is in engagement with the male thread ( 9 ) of the at least one component ( 2 ), in order to brace the components ( 2 , 3 , 4 , 5 ) against one another, and
a sealing element ( 8 ; 11 ; 17 ) disposed between the female thread ( 10 ) of the lock nut ( 6 ) and the male thread ( 9 ) of the component ( 2 ),
wherein the sealing element is embodied as a plastic ring ( 11 ) or as a shrink-fit hose ( 17 ), and
wherein the lock nut 6 further comprises a flanged-over portion ( 16 ) for fixing the plastic ring ( 11 ).
