.The concentricity of the threaded part and the polished rod part overcomes the long-term problems of easy distortion and 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 sealing. Good 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 inaccurate. 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 adopts the precision of a grinder It is not high and 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, , . The parts are indexed using a milling machine indexing plate, which is slow to process, has many processes, and takes a long time.
< r, r, , < r#>Advantages of using bellows and electric valve stems in valve products
< r, r, , .The opening and closing torque of the valve is small, and it is easy to open, 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
