Parameters: maximum pressure: ≤ 1.8MPa maximum temperature: ≤ 220 ° C maximum speed: ≤ 100RPM Suitable medium: saturated steam, superheated steam, superheated water structural features: the siphon elbow is designed for low-speed (≤ 80RPM) dryer design , release heat and the condensate is discharged siphon device for steam heating. This structure using the hinge connection, easy to install, easy to maintain, between the use of elbows then after finishing the ball head and in contact with the inner hole sealed rely siphon own weight, easy to form a good static sealing, good sealing effect , rely on the siphon and the rotary joint to the differential pressure of the intake port is easy to achieve a siphon, to achieve good drainage purposes.
