   On   connaît   déjà des elapets automatiques d'ar- rête de vapeur à double effet, tel que celai représenté en coupe longitudinale et en coupe transversale sur les figures 1 et 2: la corps de ce clapet est constitué en deux moitiés 101 102, perlant les deux sièges 111 112 sur lesquels viennent s'appliquer les clapets 121 122, actionnés par des leviers de commande 131 132. 



   Les deux moitiés 101 102 du corps de   olapet,   ménagent entre elles un joint transversal 15, dont l'é- tanchéité est toujours difficile à assurer d'une façon complète., surtout aux pressions très élevées. 



   La présente invention a pour but de perfection- ner ces clapets connus, de manière à écarter ces   diffi-

 calté d'étanchéité de joint. 



   Elle concerne un clapet d'arrêt de vap eur à double effet caractérisé par ce que le corps de clapet en est une seule et même pièce, le siège de chaque cla- pet étant rapportée dans la tubulure correspondante de   ce   corps, pour permettre le montage des clapets dans le corps avant la mise en place de leurs sièges, cette dis- position de corps de clapet en une seule pièce   suppri-   mant tout joint dans la constitution de ce corps et évitant les difficultés d'étanchéité inhérentes   à   ces joints-. 



   Unclapet d'arrêt de vapeur à double effet con- forme à l'invention, est représenté   à   titre d'exemple sur le dessin ci-joint dans lequel les figures 3 et 4 sont respectivement une coupe axiale et une coupe trans-   versale   de ce clapet. 



    @ @ @ ..   



   Le corps de ,clapet   -10   est en une seule pièce et      présente deux tubulures 30  30 .   dans lesquelles sont montées, de façon amovible, des douilles 311 312, dont les extrémités forment les sièges 111 112 des deux cla- pets 121 122, qui   coulissant   sur l'axe central 32. 



     Le     diamètre   D c'alésage intérieur des tubulures 301 302 est choisi supérieur au diamètre extérieur d des clapets 121 122. 



   On peut donc faire le montage du dispositif de la manière   suivante:   on engage dans les tubulures 301 302   les/clapets     la 3,   122, ce qui est rendu possible par la différence des diamètres D- et d, et on monte ces cla- pets sur l'axe central   3%,puis   on engage à force les douilles 311 312 dans les tubulures 301   30 : 2   le montage est terminé. 



   On réalise ainsi nn obturateur   à   double clapet dont le corps   10   est en une seule pièce, ce qui permet évidemment de supprimer les joints 15 des clapets dou-

   Double-acting automatic steam shut-off valves are already known, such as that shown in longitudinal section and in transverse section in FIGS. 1 and 2: the body of this valve consists of two halves 101 102, beading them. two seats 111 112 on which the valves 121 122 are applied, actuated by control levers 131 132.



   The two halves 101 102 of the valve body form between them a transverse seal 15, the sealing of which is always difficult to ensure completely, especially at very high pressures.



   The object of the present invention is to improve these known valves, so as to eliminate these difficulties.

 seal seal.



   It relates to a double-acting vapor shut-off valve characterized in that the valve body is one and the same part, the seat of each valve being attached to the corresponding pipe of this body, to allow assembly. valves in the body before the installation of their seats, this arrangement of a valve body in one piece eliminating any seal in the constitution of this body and avoiding the sealing difficulties inherent in these seals.



   A double-acting steam shut-off valve in accordance with the invention is shown by way of example in the accompanying drawing in which Figures 3 and 4 are respectively an axial section and a transverse section thereof. valve.



    @ @ @ ..



   The body of the valve -10 is in one piece and has two pipes 30 30. in which are mounted, removably, sockets 311 312, the ends of which form the seats 111 112 of the two valves 121 122, which slide on the central axis 32.



     The diameter D of the internal bore of the pipes 301 302 is chosen to be greater than the external diameter d of the valves 121 122.



   The device can therefore be assembled as follows: the valves 1a 3, 122 are engaged in the pipes 301 302, which is made possible by the difference in the diameters D- and d, and these valves are fitted. on the central axis 3%, then the bushes 311 312 are forcibly engaged in the pipes 301 30: 2 assembly is completed.



   A double-valve shutter is thus produced, the body 10 of which is in one piece, which obviously makes it possible to eliminate the seals 15 of the double-valve valves.
