QS-Y type rotary joint is a specialized fluid conveying component designed for the printing and dyeing industry and papermaking enterprises, mainly used for steam and hot water medium transmission in standard drying cylinders and other equipment

1、QS-Y type rotary joint – suitable for the printing and dyeing industry
The QS-Y rotary joint is specially designed for the standard drying cylinder in the printing and dyeing industry. It adopts a reliable spherical friction sealing structure. The rotary joint has a simple structure, can automatically adjust the center, and has an automatic compensator; There are two types of connecting threads, metric M36 * 4 and 45 * 3, and they are equipped with dedicated siphon hoses, making replacement and matching very convenient. Application parameter range: Temperature structure, it can automatically adjust center, automatic compensation degree ≤ 220 ℃, pressure ≤ 1.8 Mpa, speed ≤ 100 RPM.

2、Core Structure and Characteristics
Spherical sealing structure: The interior adopts a single or double spherical friction sealing design, combined with finely ground spherical and bottom surfaces to ensure a tight fit of the sealing surface. This structure allows the joint to automatically adjust its center within a certain angle range, adapting to equipment with lower rotational accuracy.
Maintenance free design: Some models (such as QS-YM series) use graphite rings as sealing elements, which have the characteristic of lifetime no need to add lubricants, achieving true maintenance free operation.
Simple structure: with a small number of internal parts (usually only four main parts), easy assembly, low failure rate, and convenient for quick replacement and maintenance.
Convenient matching: Equipped with a dedicated siphon hose, it not only solves the problem of condensate discharge, but also makes the replacement and matching of joints more flexible and convenient.
