" SOUPAPE DE FORGE DES BOUES POUR CHAUDIERES"
Les soupapes à vis ont l'inconvénient de nécessiter un temps très long pour l'ouverture et pour la fermeture et par suite l'évacuation ne peut être rapide. De plus, le 1 chauffeur doit se rendre dans la
<Desc/Clms Page number 2>
fosse pour actionner la soupape.
Avec une soupape à fermeture brusque, l'éva- ouation peut se faire rapidement, mais une telle soupape est fermée par la pression de l'eau de la chaudière et par suite il arrive souvent que la fermeture n'est pas hermétique. C'est pourquoi il est recommandé dans le cas d'emploi d'une soupape à fer- meture brusque de disposer en avant de celle-ci, une soupape à vis.
La présente invention a pour objet une sou- pape qui fonctionne aussi bien comme soupape à fer- meture brusque que comme soupape à vis de manière à permettre une évacuation rapide des boues ainsi qu'une puverture et une fermeture effectuées à la main comme dans les soupapes à vis ordinaires. D'autre part, cette sou- pape ne nécessite pas l'adjonction d'une seonde sou- pape.
Aux dessins annexés on a représenté à titre d'exemple, une forme de réalisation de l'invention.
La commande de la soupape se fait normalement
<Desc/Clms Page number 3>
par abaissement de la pédale a, ce qui fait descendre la tige b et le plateau de la soupapeo Lorsqu'on abandonne la pédale, le ressort g rappelle le pla- teau e qui est de plus fermé par la pression de la chaudière. Si cette pression ne suffisait pas à fer- mer la soupape;) celle-ci pourrait être fermée à la main par rotation du Volent 0 comme dans une soupa- pe à via ordinaireo
A cet effet le volant est,Suivant l'in-
EMI3.1
ventiont, réuni à un maehon filetée qui dans la rotation du manshen e se visse vers le haut et appuie contre le collier g qui est fixé sur la tige b.
Par rotation du manchon :? en sens inverse on produit l'ouverture de la soupape ce qui est avantageux par exemple quand la tige est coincée dans son guide ou quand la chaudière doit être abandonnée pendant un certain temps et que la. soupape doit par suite rester ouvertes
Il est bien entendu que l'invention n'est pas limitée à la forme d'exécution représentée qui a été simplement donnée à titre d'exemple,

"SLUDGE FORGE VALVE FOR BOILERS"
Screw valves have the drawback of requiring a very long time for opening and for closing and consequently evacuation cannot be rapid. In addition, the 1st driver must go to the
<Desc / Clms Page number 2>
pit to operate the valve.
With a snap-closing valve, the evacuation can be done quickly, but such a valve is closed by the pressure of the water from the boiler and therefore it often happens that the closure is not hermetic. This is why it is recommended, in the case of a snap-closing valve, to have a screw valve in front of it.
The object of the present invention is a valve which functions both as a snap-on valve and as a screw valve so as to allow rapid evacuation of sludge as well as opening and closing carried out by hand as in the ordinary screw valves. On the other hand, this valve does not require the addition of a second valve.
In the accompanying drawings, an embodiment of the invention has been shown by way of example.
The valve is operated normally
<Desc / Clms Page number 3>
by lowering the pedal a, which lowers the rod b and the valve plate o When the pedal is released, the spring g recalls the plate e which is also closed by pressure from the boiler. If this pressure was not enough to close the valve;) it could be closed by hand by turning the Volant 0 as in an ordinary via valve.
For this purpose the handwheel is, According to the in-
EMI3.1
ventiont, joined to a threaded maehon which in the rotation of the manshen e screws up and presses against the clamp g which is fixed on the rod b.
By rotation of the sleeve:? in the opposite direction, the valve opens, which is advantageous, for example, when the rod is stuck in its guide or when the boiler must be abandoned for a certain time and the. valve must therefore remain open
It is understood that the invention is not limited to the embodiment shown which was simply given by way of example,
