Abstract

The valve component is rotatably located in a housing (16), and has a vertical shaft (18) extending outside the housing for coupling with a key grip (13) on a bar (11) extending to ground level. To permit coupling between the key bar and the valve shaft (18) from ground level, the bar (10), ahead of the key grip (13), has a converging, pref. conical guide surface (12), and in the key grip (13) is a lock component (14) for relative axial locking between the valve shaft and the key bar in one direction.

Description

458 865 10 15 20 25 30 35 Beskrivning av ritningen Uppfinningen kommer i det följande att närmare beskrivas med hänvisning till ett på bifogade ritning visat utföringsexempel. 458 865 10 15 20 25 30 35 Description of the drawing The invention will be described in more detail below with reference to an exemplary embodiment shown in the accompanying drawing.

Fig. 1 visar ett vertikalt snitt genom en nyckelstáng enligt uppfinningen samt en ventil till vilken den skall anslutas.Fig. 1 shows a vertical section through a key bar according to the invention and a valve to which it is to be connected.

Fig. 2 visar en ändvy av nyckelstàngen.Fig. 2 shows an end view of the key bar.

Beskrivning av utföringsexempel Den uppfinningsenliga nyckelstàngen innefattar en hylsdel 10, vilken är fästad till en stång ll. Hylsdelen 10 uppvisar vid sin fria ände en konisk öppning eller styryta 12, som övergår i ett hal 13 med orunt tvärsnitt, t.ex. ett fyrkantshàl, fungerande som nyckeltag. Hylsdelen 10 består av tvâ mot varandra fixerade halvor och i ett spår i fyrkantshàlet 13 är placerat en làsbricka 14 med ett antal fjädrande làstungor 15 som uppvisar skärkanter.Description of exemplary embodiments The key rod according to the invention comprises a sleeve part 10, which is attached to a rod 11. The sleeve part 10 has at its free end a conical opening or guide surface 12, which turns into a hall 13 with an orange cross-section, e.g. a square hole, acting as a keyhole. The sleeve part 10 consists of two halves fixed to each other and in a groove in the square hole 13 a locking washer 14 is placed with a number of resilient locking tongues 15 which have cutting edges.

Vattenledningsventilen, som är avsedd att manövreras medelst nyckelstàngen är betecknad med 16. Den består av ett ventilhus 17 i vilket ett ventilelement (ej visat) är vridbart lagrat kring en väsentligen vertikal axel och vars ventilaxel 18 sträcker sig utanför ventilhuset 17 och har ett mot nyckelstàngens nyckeltag 14 svarande tvärsnitt.The water supply valve, which is intended to be operated by means of the key bar, is denoted by 16. It consists of a valve housing 17 in which a valve element (not shown) is rotatably mounted about a substantially vertical axis and whose valve shaft 18 extends outside the valve housing 17 and has one against the key bar key tag 14 corresponding cross section.

Stàngen ll har en längd som svarar* mot det djup pà vilket ventilen 16 befinner sig och uppvisar lämpligen ett teleskopiskt parti, så att längden kan justeras.The rod 11 has a length corresponding to * the depth at which the valve 16 is located and suitably has a telescopic portion, so that the length can be adjusted.

Sammankopplingen mellan nyckelstàngens hylsdel 10 och ventilaxeln 18 kan ske från marknivá, genom den koniska styrytan 12 som söker upp ventilaxeln 18. Därefter kan nyckeltaget 13 styras in över ventilaxeln 18, varvid denna låses medelst làsbrickan 14, vars skärkanter skär in i ventilaxeln 18 och förhindrar isärkoppling mellan denna och hylsdelen 10. En nyckelstàng som lossnat från ventilaxeln kan således enkelt bytas ut från marknivà utan föregående schaktning ned till. ventilen. Den uppfinningsenliga nyckelstàngen kan naturligtvis även användas vid nyanläggningar. 458 865 3 Uppfinningen är naturligtvis inte begränsad till det visade utföringsexempel utan kan modifieras inom ramen för de efter- följ ande patentkraven .The connection between the sleeve part 10 of the key bar and the valve shaft 18 can take place from ground level, through the conical guide surface 12 which seeks out the valve shaft 18. Thereafter the key catch 13 can be guided over the valve shaft 18, which is locked by the lock washer 14. disconnection between this and the sleeve part 10. A key bar that has come loose from the valve shaft can thus be easily replaced from ground level without prior excavation down to. the valve. The key bar according to the invention can of course also be used in new installations. The invention is of course not limited to the exemplary embodiment shown but can be modified within the scope of the appended claims.
