Abstract

An adjustable safety coupling for fluidtight interconnection with an opposite nipple 12 comprises a valve housing 2 with a sleeve 6 which is rotatable externally thereon and a valve body 9 which is arranged in the housing and is spring-loaded towards its closing position, in which it bears against a valve seat 8 formed in the housing 2. The safety coupling also comprises a number of locking balls 15; 16 resting in a groove arranged on the inside of the sleeve 6, which balls are arranged so as, when the sleeve 6 is rotated, to interact with an inclined surface 14 of the groove of the sleeve 6 for displacement of the nipple 12 in relation to the housing 2 and operation of the valve body 9 and also securing of the nipple 12 in the housing 2, the balls 15; 16 being mounted in a radially displaced manner in two or more axially displaced rows of holes in the valve housing 2. The inclined surface 14 in the sleeve 6 interacts first with the row of balls 15 located closest to the insertion end and then successively with the subsequent rows of balls 16 for radial displacement of the nipple 12 and operation of the valve body 9. <IMAGE>

Description

15 20 25 30 35 40 465 793 en därav följande mycket fin regleringsmöjlighet av fluid- strömmen, genom att den ena gruppen kulor först kommer att dra med nippeln och när deras möjlighet att transportera nippeln vidare är avslutad, övertar nästa grupp kulor uppgiften och transporterar nippeln vidare. Ventilkroppen är av säkerhets- mässiga skäl placerat inuti och företrädesvis helt i bottnen av ventilhuset, så att möjligheten för utlösning av ventilen endast föreligger då en främmande kropp förs in i ventilhuset och ned i bottnen, vilket är ganska svart om det göres oav- siktligt. 15 20 25 30 35 40 465 793 a consequent very fine control possibility of the fluid flow, in that one group of balls will first pull with the nipple and when their ability to transport the nipple further is completed, the next group of balls takes over the task and transports the nipple further. For safety reasons, the valve body is located inside and preferably completely at the bottom of the valve housing, so that the possibility of triggering the valve only exists when a foreign body is inserted into the valve housing and down into the bottom, which is quite black if done unintentionally.

Enligt uppfinningen kan kopplingen vara anordnad så att nippeln under den första delen av förskjutningen ej påverkar ventilkroppen, och att i detta sammanhang således ventilkropp- en påverkas först när den andra kulraden samverkar med hylsans snedyta.According to the invention, the coupling can be arranged so that the nipple during the first part of the displacement does not affect the valve body, and that in this context the valve body is thus only affected when the second row of balls cooperates with the inclined surface of the sleeve.

Härvid uppnås säkerhet för att nippeln kan avlägsnas först när ventilen är stängd och därvid spärrar mot en fluids- tröm genom kopplingen.This ensures that the nipple can only be removed when the valve is closed and thereby blocks against a fluid flow through the coupling.

Uppfinningen beskrives närmare nedan med hänvisning till bifogad ritning, på vilken fig, 1 visar säkerhetskopplingen i ett axiellt snitt från sidan; fig, 2 visar säkerhetskopplingen i ett axiellt snitt fràn sidna med isatt nippelstycke; fig, 3 visar nippelstycket; och fig, 4 visar ventilhuset med hål för förskjutet monterade kulor.The invention is described in more detail below with reference to the accompanying drawing, in which Fig. 1 shows the safety coupling in an axial section from the side; Fig. 2 shows the safety coupling in an axial section from the side with the nipple piece inserted; Fig. 3 shows the nipple piece; and Fig. 4 shows the valve housing with holes for offset mounted balls.

Säkerhetskopplingen 1 består av ett ventilhus 2 som är försett med i axiell riktning förskjutna hål 3 för kulspärren 4 och som dessutom uppvisar en utvändig gänga för en hylsa 6.The safety coupling 1 consists of a valve housing 2 which is provided with holes 3 offset in the axial direction for the ball latch 4 and which also has an external thread for a sleeve 6.

Ventilhuset är vidare försett med en packning 7, som tätar mot nippelns huvud 12a, och en tätningsyta 8 mot ventil- huset 9, vilket är försett med en packning 10 för anliggning mot ytan 8, samt en skruvfjäder 11, vilken säkerställer att ventilkroppen stänger när nippeln 12 uttages. Ventilkroppen är tillika försedd med utströmningshàl 13, genom vilka en fluid kan uttränga vid öppen ventil. Hylsan 6 har invändigt en snedyta 14, vilken vid rotationsrörelse av muffen förskjutes axiellt över kulorna 15 och 16 och pressar den första gruppen kulor 15 in mot snedytan 18 och låser i ett spår 17 i nippeln 12 samt därefter den andra gruppen kulor 16 och eventuellt flera. Ventilhuset kan vidare vara försett med en backventil vid 21. 10 15 20 25 793 muffen när En ansats 19 på hylsan 6 verkar som stoppqšög den kommer till anslag mot ventilhusets yta 20, varvid i detta läge inses att ytan 14 pressar kulorna 15 och 16 helt in i spåret 17, och varvid i detta läge ventilen är öppen och nippeln fasthàllen. I detta läge är det vidare möjligt att direkt fastlàsa kopplingen, så den ej omedelbart kan åtskil- jas. Medel för denna fastlàsníng visas ej.The valve housing is further provided with a gasket 7, which seals against the nipple head 12a, and a sealing surface 8 against the valve housing 9, which is provided with a gasket 10 for abutment against the surface 8, and a helical spring 11, which ensures that the valve body closes when the nipple 12 is removed. The valve body is also provided with outflow holes 13, through which a fluid can escape when the valve is open. The sleeve 6 has internally an inclined surface 14, which during rotational movement of the sleeve is displaced axially over the balls 15 and 16 and presses the first group of balls 15 against the inclined surface 18 and locks in a groove 17 in the nipple 12 and then the second group of balls 16 and possibly more . The valve housing may further be provided with a non-return valve at 21. the sleeve 19 When a shoulder 19 on the sleeve 6 acts as a stop eye it comes to abut against the surface 20 of the valve housing, it being realized in this position that the surface 14 presses the balls 15 and 16 completely into the groove 17, and in this position the valve is open and the nipple is held. In this position, it is also possible to lock the coupling directly, so that it cannot be separated immediately. Means for this locking are not displayed.

Vid sammankoppling föres nippelns huvud in i ventilhuset till anslag mot husets packning. Hylsan tilldelas därefter en rotationsrörelse, vilken förskjuter den mot ventilhusets tätningsyta 8, varvid snedytan 14 pressar kulorna, först kulorna 15 och sedan kulorna 16, genom hålen 3 till anliggning mot snedytan 18, vilket medför en axiell förskjutning av nippeln in i ventilhuset och en påverkan av ventilkroppen, vilket först sker vid en tidpunkt då kulorna ej längre tillåt- er uttagning av nippeln.When connected, the nipple head is inserted into the valve housing for abutment against the housing gasket. The sleeve is then assigned a rotational movement, which displaces it against the sealing surface 8 of the valve housing, the inclined surface 14 pressing the balls, first the balls 15 and then the balls 16, through the holes 3 to abut against the inclined surface 18, which causes an axial displacement of the nipple into the valve housing. of the valve body, which only takes place at a time when the balls no longer allow removal of the nipple.

Det kommer att inses att detta, att först en grupp kulor pàverkar nippeln till transport mot ventilkroppen och begyn- nande öppning av denna och att därefter nästa grupp kulor fullt öppnar ventilen, tillhandahåller en långt bättre reg- leringsmöjlighet än tidigare. Man kan samtidigt påverka hylsan riskfritt, ty om man vrider sà mycket att nippeln släppas är ventilen stängd.It will be appreciated that this, that first a group of balls affects the nipple for transport towards the valve body and initial opening thereof and that then the next group of balls fully opens the valve, provides a far better control possibility than before. At the same time, the sleeve can be actuated without risk, because if you turn it so much that the nipple is released, the valve is closed.

Det kommer att vara möjligt att ansluta olika extra utrustningar i kopplingens båda ändar, såsom en utströmnings- stuts, olika inre och yttre gängor för montering och dessutom backventilegenskaper.It will be possible to connect various additional equipment at both ends of the coupling, such as an outflow connection, various internal and external threads for mounting and also non-return valve properties.
