.The concentricity of the threaded part and the polished rod part overcomes the long-term problems of easy distortion and easy damage to the rolling die in the domestic thread rolling process.
.The turning part is formed in one step using CNC technology, with high precision and smooth turning. Good sealing performance.
.The end groove adopts forging process, which has high efficiency and low cost.
< r, r, , . < r#>Characteristics of traditional valve stem:
< r, r, , . .The traditional valve stem thread uses a spiral flying knife, and the thread accuracy is inaccurate. The traditional chipless thread rolling is used to wear the rolling die, which is easy to deform and twist.
< r, r, , .. Polished rod The accuracy of grinding machine is not high and it takes a long time.
< r, r, , .. The inverted part is clamped twice and turned around to pull down the seal. The concentricity is poor and the inverted seal is easy to leak.
< r, r, , . .The end part is indexed by a milling machine indexing plate, which is slow to process, has many procedures, and takes a long time.
