Abstract

The directional injector check valve comprises a body containing a valve seat formed by the taper end of a bush with fluid flow ports and a guide opening for a stem fixed to the valve plate. The plate has a peripheral groove accommodating a toroidal joint forming a seal against the seat. The body outlet is screwed to accommodate the injector, which comprises a sleeve with an external end collar, and a tube with a head covering the collar. The head contains an oblique orifice connected to the interior of the body, and is adjustable for angle.

Description

L'invention concerne un clapet de retenue
Le clapet de retenue de l'invention se compose d'un corps recevant un siège de clapet pour un clapet et est caractérisé en ce que le siège de clapet est formé par 1 extrémité tronconique de la face interne d'une bague9 cette bague étant pourvue à son extrémité opposée d'orifices pour l'écoulement du fluide et d'un orifice axial pour le guidage d'une tige soli daire du clapet, ce clapet se composant d8un disque pourvu d'une gorge périphérique recevant un joint d'étanchéité torique s'adaptant sur le siège tronconique0
Suivant une autre caractéristique de l'invention, le joint torique est appliqué contre le siège tronconique par un ressort disposé autour de la tige de clapet et s'appuyant d'une part sur la bague, d'autre part sur une tête de la tige.The invention relates to a check valve.
The check valve of the invention consists of a body receiving a valve seat for a valve and is characterized in that the valve seat is formed by 1 frustoconical end of the inner face of a ring9 this ring being provided at its opposite end of holes for the flow of the fluid and an axial hole for guiding a solid rod of the valve, this valve consisting of a disc provided with a peripheral groove receiving an O-ring seal adapting to the tapered seat0
According to another characteristic of the invention, the O-ring is applied against the frustoconical seat by a spring arranged around the valve stem and resting on the one hand on the ring, on the other hand on a head of the stem .

Suivant une autre caractéristique de l'invention, le corps est réalisé en deux parties seassemblant par vissage, le joint torique étant serré par ses extrémités entre deux gorge3 internes iormees sur chacune des parties du corps
l'invention es représentée, à titre d'exemple non limitatif, sur les dessins ci-joints, dans lesquels
la figure 1 représente, en deux demi-coupes axiales, le clapet en position d'ouverture et en position de fermeture
- la figure 2 est une vlle en coupe suivant A-L de la figure 1.According to another characteristic of the invention, the body is made in two seassembling parts by screwing, the O-ring being clamped by its ends between two internal grooves 3 iormees on each of the parts of the body
the invention is shown, by way of nonlimiting example, in the accompanying drawings, in which
Figure 1 shows, in two axial half-sections, the valve in the open position and in the closed position
- Figure 2 is a sectional vlle along AL of Figure 1.

La présente invention a9 en conséquence, pour but la réalisation d'un clapet de retenue, notamment pour liquide, qui soit d'une bonne fiabilité et d 'une bonne étanchéité9 ce clapet assurant l'auto-nettoyage du siège qui le reçoit
Dans l'exemple représenté sur les dessins ci- joints le clapet de retenue se compose d'un corps réalisé en deux parties 1 et 2 qui sont pourvues l'une 1 d'un orifice de pénétration du fluide i l'autre 2 d'un orifice 21 de sortie de ce fluide.The present invention a9 consequently, for the purpose of achieving a check valve, in particular for liquid, which is of good reliability and good sealing9 this valve ensuring self-cleaning of the seat which receives it
In the example shown in the attached drawings, the check valve consists of a body made up of two parts 1 and 2 which are provided one with a fluid penetration orifice with the other 2 with an orifice 21 for the outlet of this fluid.

Ces deux parties s'assemblent par vissage en 3 sur un plan de jointoiement 4. These two parts are assembled by screwing in 3 on a jointing plane 4.

A l'intérieur de la partie 1 est disposée une bague 5 qui serrée en un épaulement interne 12 de la-partie 1 et un siège interne 12 de la partie 2. Inside the part 1 is arranged a ring 5 which clamps into an internal shoulder 12 of the part-1 and an internal seat 12 of the part 2.

l'extrémité de la bague 5, située sur le plan de jointoiement 4, est pourvue d'une gorge 51 dans lequel est logé un joint torique 6, ce joint s'appliquant ainsi, lors du serrage des deux parties du corps, à la fois contre ces deux parties de corps et contre la bague 5, afin de réaliser l'étanchéité de l'assemblage des deux parties du corps entre elles9 ainsi que l'étanchéité de chacune de ees deux parties 1 et 2 par rapport à la bague 5. the end of the ring 5, located on the jointing plane 4, is provided with a groove 51 in which an O-ring 6 is housed, this seal thus applying, when the two parts of the body are tightened, to the both against these two body parts and against the ring 5, in order to achieve the sealing of the assembly of the two body parts between them9 as well as the sealing of each of these two parts 1 and 2 with respect to the ring 5 .

Cette bague 5, est pourvue, sur sa face interne, d'une extrémité conique 52 formant le siège de clapet et contre laquelle est destiné à venir s'appliquer le joint torique 7 du claquet proprement dit. This ring 5 is provided, on its internal face, with a conical end 52 forming the valve seat and against which is intended to come to apply the O-ring 7 of the valve itself.

Ce clapet est constitué par un disque 8 pourvu
d'une gorge annulaire péripherique 81 dans laquelle vient se loger le Joint torique 7, ce disque 8 étant pourvu d'un orifice taraudé axial dans lequel vient se visser une tige de clapet 9 pourvue d'une tête
Par ailleurs, la bague 5 est pourvue d'un fond 53 à son extrémité opposée à celle comportant le tronc de cône cette extrémité 53 (voir figure 2) étant pourvue d'un orifice axial 54 entouré par d'autres orifices 55, l'orifice axial 54 correspondant sensiblement au diamètre de la tige 9 qu'il reçoit à coulissement, tandis que les orifices 55 sont destinés à permettre l'écoulement du fluide.This valve is constituted by a disc 8 provided
an annular peripheral groove 81 in which the O-ring 7 is housed, this disc 8 being provided with an axial threaded orifice in which a valve stem 9 provided with a head is screwed
Furthermore, the ring 5 is provided with a bottom 53 at its end opposite to that comprising the truncated cone, this end 53 (see FIG. 2) being provided with an axial orifice 54 surrounded by other orifices 55, the axial orifice 54 corresponding substantially to the diameter of the rod 9 which it receives by sliding, while the orifices 55 are intended to allow the fluid to flow.

Entre ce fond perforé 53 et la tette 91 de la tige 9, est disposé ressort hélicoïdal 10 qui tend constamment à appliquer le joint torique 7 contre la surface tronconique 52. Between this perforated bottom 53 and the plate 91 of the rod 9, is disposed a helical spring 10 which constantly tends to apply the O-ring 7 against the frustoconical surface 52.

Ainsi, lorsqu'un fluide sous pression est amené par l'orifice 11, celui-ci exerce une pression sur le clapet 8 à l'encontre du ressort 10, ce qui sépare le joint torique 7 de la surface tronconique 52 pour permettre l'écoulement du fluide. Thus, when a pressurized fluid is brought in through the orifice 11, the latter exerts pressure on the valve 8 against the spring 10, which separates the O-ring 7 from the frustoconical surface 52 to allow the fluid flow.

Par contre, lorsque le fluide ne s'écoule plus par l'orifice 11, le joint torique 7 vient s'appliquer contre la surface tronconiquq 52 sous l'action du ressort 10, afin de constituer un montage étanche évitant le retour du fluide de l'orifice 21 vers l'orifice 11. On the other hand, when the fluid no longer flows through the orifice 11, the O-ring 7 is applied against the frustoconical surface 52 under the action of the spring 10, in order to constitute a sealed assembly preventing the return of the fluid orifice 21 towards orifice 11.

On constate par ailleurs que, lors de la fermeture de ce clapet, le joint torique 7 vient s'appliquer progressivement sur la surface tronconique pour repousser les impuretés qui auraient pu s'y déposer et réaliser ainsi un auto-nettoyage du clapet. It can also be seen that, when this valve is closed, the O-ring 7 is gradually applied to the frustoconical surface to repel impurities which could have deposited there and thus carry out self-cleaning of the valve.
