Abstract

L'invention concerne une soupape de raccord d'un conditionneur d'air séparé comprenant deux tuyaux de raccord dont un à surface conique creuse et l'autre à surface convexe sphérique. Les deux surfaces entrent en contact linéaire grâce à un écrou du tuyau de raccord. Le diamètre le plus extérieur de la surface convexe est supérieur aux diamètre intérieur du tuyau de raccord extérieur et ≤ au diamètre extérieur du tuyau de raccord extérieur. L'écrou du tuyau de raccord peut bloquer directement le corps sphérique de la surface convexe et assembler les deux tuyaux de raccord de manière à augmenter le rendement et la fiabilité du produit.
