Description

Soupape darret pour conduites ä: fluide sous pression. La presente invention a pour objet une soupape darret pour conduites ä fluide saus pression, comportant un boitier ä passaltes d'entree et de sortie, un .siege cle soupape en- tre ces passaltes, un organe filetc- vissf@ dann un taraudage cl'une Partie du boitier et por- tant une bille de soupape au moyen dune cage amovible ouverte en hout, et une tige de manoeuvre pouvant, tourner, sann pouvoir se deplacer axialement. comportant un col- let de garniture conique ain:si qu'une saillie d'attaque reliee, ä .coulüssement, avec 1'or- gane porte-bille de telle Sorte que, en tour nant la tige de manceuvre, an puisse faire tourner 1'organe porte-bille dann son tarau- dage et 1e deplacer par Suite axialement pour rapprocher ou äcarte.r la bille de son siege. Shut-off valve for lines ä: medium under pressure. The subject of the present invention is a shut-off valve for pressurized fluid pipes, comprising a casing with inlet and outlet passages, a valve seat between these passages, a threaded member in a tapping cl' a Part of the case and carrying a valve ball by means of a removable cage open at the top, and an operating rod which can rotate, without being able to move axially. comprising a tapered packing collar as well as a leading protrusion slidably connected with the ball-carrying member so that, by turning the operating rod, it can rotate the ball-carrying member in its internal thread and subsequently move it axially to bring the ball closer to or away from its seat.

Le dessin ei-annexe represente, ä titre d'exemple, en coupe verticale, une forme d'execut:ion de la soupa.pe darret selon la presente Invention. The attached drawing represents, by way of example, in vertical section, a form of execution: ion of the soupa.pe stop according to the present invention.

Dans ce dessin, 1 designe 1e Passage cI'entree dune conduite ä relier ä une source fournissant un liquide sous Pression, par exem.ple, et 2 designe 1e passalte de sortie de cette conduite :a.llant ä un mecanisme ä actionner par 1e liquide sous pression. Ces passaltes cl'entree et de sortie pourraient etre inverses, mais il y a avantag:e ä clisposer 1e passalte cl'entree 1 derriere la soupape, car par cette disposition la pression du liquide tend ä. maintenir la s.oupape fermee. In this drawing, 1 denotes the entry passage of a pipe to be connected to a source supplying a liquid under pressure, for example, and 2 denotes the exit pass of this pipe: going to a mechanism to be actuated by the liquid under pressure. These inlet and outlet passaltes could be reversed, but there is an advantage in clamping the inlet passalte 1 behind the valve, because by this arrangement the pressure of the liquid tends to increase. keep the valve closed.

Entre c.es passaltes d'entree et de sortie est prevue une bille 3 formant 1'element ob- turateur de la soupape, suscept.ible d'etre re- glee en Position en se rapprochant .et en s'ecartant de son si@g:e 4 au moyen de 1'or- gane porte-bille 5 pourvu d'un filetalte et. au- quel 1,a bille est reteiiue au moyen dune Gage ou lanterne 6 qui y est r eliee dune maniere amovible et est ouverte en bout. Un bout,on-poussoir 6@, verrouille Sur 1'organe 5 au moyen dune 1--oupille 5il mainfient la bille 3 en pla.ce. L'organe filete 5 est atta- que inferieurement par une Partie ca.rree solidaire dune tige de lnanceuvre rotative 'i qui est. munie Tun collet de garniture co- nique V', lequel Fait j.oint etanehe avec un siege tronconique S prevu cl-ans une d.ouille 9, laduelle est reliee ri--ide:ment au boitier principal 11 gräee ä. un filetage 1U clont eile esst pourvue et qui est engage darrs un tarau- dag du boitie:r ii. Between these inlet and outlet passages is provided a ball 3 forming the obturator element of the valve, capable of being adjusted in position by approaching and deviating from its position. @g: e 4 by means of the ball carrier 5 provided with a filetalte and. in which 1, a ball is reteiiue by means of a Gage or lantern 6 which is r eliee therein in a removable manner and is open at the end. A bout, on-push 6@, locks Sur 1'organe 5 by means of a dune 1--oupille 5il mainfient the ball 3 in pla.ce. The threaded member 5 is attacked below by a Part ca.rree secured to a rod of rotary lnanceuvre 'i which is. provided with a collar of conical trim V', which is joint sealed with a frustoconical seat S provided for cl-ans a socket 9, the duelle is connected ri--ide:ment to the main box 11 gräee ä. a 1U thread is provided and which is engaged in a thread of the case: r ii.

La douille 9 presente un tarauclage Jans sa. partie interne recevarrt 1e filet.age. de 1'or- gane po:rte-bi11e :5, lequel est susceptible d'un mouvement de rotation dann ledit tarau- dage. Socket 9 has a Jans sa tapping. internal part receives the 1st thread.age. of the organ po: rte-bi11e: 5, which is capable of a rotational movement dann said tapping.

L'extremite exteine et carree 'ih de la tige de manoeuvre 'i est rigidement reliee ä un volant de manoeuvr-e 12 et est situee de fa- con que 1e collet d'et.ancheite 7a fasse joint Manche Sur son siege et puisse etre bloque dans cette position au moyen Tun contre- ecrou ä poi ;-nee i3.<B>Co</B> co-ntre-ecrou n'est pas toujours ne:cessaire, mais il est desi.rable de 1e pro voir, en particulier lorsque la sou- pape est susceptible d'Mre soumise ä des vi- brations. The external and square end 'ih of the control rod 'i is rigidly connected to a control wheel 12 and is located so that the sealing collar 7a makes a joint on its seat and can be blocked in this position by means of a counter-nut with poi;-nee i3.<B>Co</B> counter-nut is not always necessary, but it is desirable to see it , in particular when the valve is likely to be subjected to vibrations.

Cependant, par Suite de sa rotation, il. con imunique uri nrouvenrer:(, de rotation ä 1'organe 5 qui, airisi qz.i'on 1'a dit ei-dessus, porte la bille de soupape 3 dans la cage 6.

Une sou- pape construite ainsi qu'il a MP dit restera clams sa position de reglage en depit des vi- bra.tions et, en outre, le liquide sous@ pression est empeclte de fuir e'c de passec ä 1'arriere du collet conique 7a qui reste toujours Sur son siege. Use the valve in the following manner: Loosen the lock nut ä, handle t3 and an Rotate the operating rod 7 which however does not move longitudinally, the sealing collar 7a rotating on its seat B. However, by Continuation of its rotation, it. con imunique uri nrouvenrer: (, of rotation to the member 5 which, airisi qz.i'on said above, carries the valve ball 3 in the cage 6. Etamt gives that the o: rgane 5 works by its thread in the tapping of the fixed sleeve 9. this member moves originally and brings the valve ball closer or closer to its seat, according to what is desired, after which the valve can be locked - Press it back into the set position by the handle lock 13. A valve constructed as he said will remain in its set position despite vibrations and, in Furthermore, the pressurized liquid is prevented from leaking and passing through the back of the conical collar 7a which always remains on its seat.
