Ozongeneratorer ¨ar v¨aldigt anv¨andbara vid reng¨oring och kan appliceras p˚a en m¨angd olika s¨att, bland annat rening av vatten. F¨oretaget Primozone utvecklar konkurrenskraftiga ozongeneratorer. Vid de system d¨ar ozonet tills¨atts direkt i vattnet kan ett bak˚atfl¨ode ske vid maskinfel. Generatorn ¨ ar mycket k¨anslig f¨or vatten och d¨armed beh¨ovs ett skyddande system. Primozone anv¨ander en mekatronisk skyddsventil f¨or att hindra eventuellt bak˚atfl¨odande vatten. I arbetet utvecklas en ny version av skyddsventilen ˚at Primozone d¨ar m˚alet ¨ar att reducera brister och ¨oka prestandan. Projektet resulterar i tv˚a skyddsventiler. En ren optimering av den nuvarande skyddsventilen ang˚aende bland annat pris, estetik, tillverkning, inkapsling och vikt- och materialminsking med samma prestanda. Den andra skyddsventilen erbjuder stora prestanda¨okningar och ¨ar f¨ordelaktig vid st¨orre system d¨ar annars flera skyddsventiler hade beh¨ovts anv¨andas. / Ozone generators are very useful in sanitation and can be applied in a variety of ways, including water purification. The company Primozone develops competitive ozone generators. In the systems where the ozone is added directly into the water, a backflow can occur in the event of machine failure. The generator is sensitive to water and therefore a protective system is required. Primozone uses a mechatronic protection valve to prevent any backflowing water. During this project a new version of the protection valve for Primozone is developed, where the goal is to reduce shortcomings and increase performance. The project resulted in two protective valves. One pure optimization of the current protection valve including price, aesthetics, weight, manufacturing ,encapsulation and material reduction with the same performance. The second protection valve offers high performance gains and is advantageous in larger systems where otherwise several safety valves would have been needed.
