< r, r, , < r#>< r>Features of marine valve stems:
< r, r, , . Zhifei valve stem threads are self-extruded, with high thread strength and accurate precision.
.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 easy turning. The valve sealing performance is good.
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. The thread accuracy is inaccurate and the traditional chipless thread rolling is used to wear the rolling die, which is easy to deform and twist.
< r, r, , .The polished stem part is made of The precision of the grinder is not high and it takes a long time,
< r, r, , . The reverse sealing 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, , .The end part is indexed by a milling machine indexing plate, which is slow to process, has many processes, and takes a long time.
