Yongjia Zhifei valve stem

< r#>< r>Features of the large-diameter low-temperature gate valve stem: . Zhifei valve stem threads are self-extruded, with high thread strength and accurate precision.
.Concentricity of the threaded part and the polished rod part It is consistent and has overcome the long-term problems of easy distortion and damage to the rolling die in the domestic thread rolling process.
. The switch part is formed in one step using CNC technology, with high precision and good switch sealing performance.
. The end groove adopts forging forming process, which is highly efficient and low cost.
< r#>Characteristics of traditional valve stem:
. Traditional valve stem thread uses spiral flying knife, and the thread accuracy is not accurate so traditional valve stem thread adopts spiral flying knife. Chipless thread rolling is easy to damage the rolling mold, and is easy to deform and twist.
. The grinder used for the polished rod part has low accuracy and takes a long time.
The reverse part uses two clampings to turn around and pull down the seal, and the concentricity is poor. , the inverted seal is easy to leak.
.The end part is indexed by a milling machine indexing plate, which is slow to process, has many procedures, and takes a long time.
