Pnömatik kontrol alanında kullanılan solenoid valflerde oluşan iç akışların incelendiği bu çalışmada, valf pistonunun iki farklı konumu sonucunda oluşan ve akışkanın izlediği A ve B hatlarında, hat boyunca meydana gelen basınç değişiklikleri ve hız değişimleri analiz edilmiştir. A ve B hatları içinde valf üzerinde bazı tasarım değişiklikleri yapılarak bunların etkileri gözlenmiştir. Tasarım iyileştirmeleri ile sağlanan hız ve basınç dağılımında gözlenen değişiklikler, valfte oluşan akış kayıplarının azaldığı şeklinde yorumlanmıştır.
Bu çalışma, TÜBİTAK TEYDEB tarafından desteklenen 7160675 nolu proje kapsamında gerçekleştirilmiştir.

Determination of Design Parameters in Solenoid Valves Groups By Means of Flow Analysis
In this study, the flow characteristics of a solenoid valve used in the pneumatic controls were analysed and the pressure and velocity changes along the line in the A and B lines which are formed as a result of two different positions of the valve piston are introduced. Some design changes were made on the valve in lines A and B and their effects were observed. The changes observed in the speed and pressure distribution provided by the design improvements were interpreted as an improvement in the flow losses occurring in the valve.
