.Threaded parts It is concentric with the polished rod part, overcoming the long-standing problems of easy distortion and damage to the rolling die in the domestic thread rolling process.
The switch-off part is formed in one step using CNC technology, with high precision and good switch-off sealing performance.
.The end groove adopts forging forming 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 not accurate. The traditional chipless thread rolling is easy to wear the rolling die, which is easy to deform and twist.
< r, r, , .The polished stem part uses a grinder with low accuracy. It takes a long time,
< r, r, , . The reverse part is clamped twice and turned around to pull down the seal. The concentricity is poor and the reverse seal is easy to leak.
< r, r, , . A milling machine is used at the end part. The indexing of the indexing plate is slow in processing, has many processes, and takes a long time.
