. 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 turn-off part is formed in one step using CNC technology, with high precision and good turn-off sealing performance. 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, 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 rod part uses a grinder with inaccurate accuracy. High cost, long time consumption,
< 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, , . The end part Using a milling machine indexing plate for indexing is slow in processing, has many processes, and takes a long time.
< r, r, , < r#>Advantages of using valve products< r> and marine valve stems
< r, r, , .The opening and closing torque of the valve is small, and the opening is easy, labor-saving and time-saving.
< r, r, , .The surface is smooth and the coaxiality is good. The sealing performance is high.
< r, r , , .Tensile, torsional, high strength, enhanced valve life
