Abstract

A discharge tap (10) for liquid containers, in particular for connecting to the outlet neck or the outlet opening of a transportation and storage container for liquids, having a tap housing (11) in which a valve body being pivotable around a valve axle by means of a handle (12) for opening and closing a flow cross section of an outlet tube (13) is arranged, said handle being provided with a handle stop and a housing dome of the tap housing being provided with a housing stop, said handle stop and said housing stop being able to be locked relatively to each other via a securing device (16) for securing the locking position, the securing device (16) comprising a stop bolt (17) being able to be displaceable between a bolting position and an unbolting position in a translatory manner in direction of the valve axle.

1 . 1. A discharge tap ( 10 ,  51 ) for liquid containers, in particular for connecting to the outlet neck or the outlet opening of a transportation and storage container for liquids, having a tap housing ( 11 ,  80 ) in which a valve body being pivotable around a valve axle by means of a handle ( 12 ,  52 ) for opening and closing a flow cross section ( 25 ) of an outlet tube ( 13 ) is arranged, a housing dome ( 23 ,  53 ) being formed at the outlet tube for mounting a valve shaft ( 20 ) provided with the handle at its shaft end ( 21 ) and extending out of the outlet tube, said handle being connected to the valve shaft in a torque-proof manner and being arranged on the shaft end with a hub part ( 18 ,  56 ), said hub part being provided with a handle stop ( 25 ,  69 ) for defining a shut-off position of the valve body and the housing dome being provided with a housing stop ( 27 ,  61 ), said handle stop and said housing stop being able to be locked relatively to each other via a securing device ( 16 ,  77 ) for securing the shut-off position, wherein the securing device ( 16 ,  77 ) comprises a stop bolt ( 17 ,  71 ) which is held at a guiding device arranged at the hub part ( 18 ,  56 ) and can be displaced between a locking position and an unlocking position in a translatory manner in direction of the valve axle by means of the guiding device, said stop bolt ( 17 ,  71 ), when in the locking position, being positioned in an engagement arrangement with a first bolt stop and a second bolt stop for securing the shut-off position, wherein the first stop bolt is formed by a first housing stop formed at the housing dome ( 53 ) and the second stop bolt is formed by a second housing stop formed at the housing dome and the stop bolt ( 71 ) is received between the housing stops. 
     
     
         2 . The discharge tap according to  claim 1 , wherein the first stop bolt is formed by a first axial end ( 67 ) of an edge web ( 60 ) formed circumferentially at the upper edge ( 59 ) of the housing dome ( 53 ) and the second bolt stop is formed by a second axial end ( 72 ) of the edge web ( 60 ) arranged opposite the first axial end ( 67 ).
