1. Slangbrottsventil för tryckslangar eller -ledningar (5) med omgivande skyddslang eller -ledning (14) och ett tryckmedium i ett utrynune (13) mellan tryck- och skyddsslangarna eller -ledningarna, vilken ventil har en ventilslid (1), som är förskjutbar utmed ett ventilhus (2) mellan ett öppetläge och ett genomströnuning genom ventilen förhindrande stängnings-läge och som är anordnad att stä under päverkan av nämnda tryckmedium för att av detta hällas i öppetläget mot verkan av en ventilsliden (1) i riktning mot stängningsläget efter-givligt päverkande belastningsanordning (17,55), vilken är anordnad att vid underskridande av ett undre gränsvärdestryck hos nämnda tryckmedium stänga ventilen, kännetecknad därav, att den har en tryckavlastningsanordning (19), som stär i förbindelse med nämnda utrymme (13) mellan tryck- och skyddsslangarna eller -ledningarna (15,14) och är anordnad att vid överskridande av ett Övre gränsvärdestryck i detta utrymme (13) avlasta trycket sä att ventilen stängs under in-verkan av belastningsanordningen (17,55).
2. Slangbrottsventil enligt patentkravet 1, kännetecknad därav, att den har en andra tryckavlastningsanordning (18; 80-82), vilken är anordnad att vid underskridande av det undre gränsvärdestrycket för tryckmediet i nämnda utrymme (13) avlasta detta tryck och därmed läta belastningsanordningen (17,55) förskjuta ventilsliden (1) tili stängningsläget.
3. Slangbrottsventil enligt patentkravet 2, kännetecknad därav, att den andra tryckavlastningsanordnin-gen (80-82) omfattar en i ventilsliden (1) utformad tryckav-lastningskanal (80), som mynnar pä ventilslidens (1) mot ven-tilhuset (2) vända sida med en mynning (81), vilken i venti-lens öppna läge är skild frän nämnda utrymme (13) medelst en tätning (82) , som är anordnad pä ventilhuset (2) i ett av det önskade undre gränsvärdestrycket bestämt läge, sä att ventilslidens (1) tryckavlastningskanal (80) förenas med nämnda utrymme (13), om undre gränsvärdestrycket underskrids.
