Question:

Can the stem and sphere of a ball valve be made into a whole? Did you do that? Seek specific analysis

Answer:

The ball and rod can of course be integrated (now this kind of valve is also a lot of it), and the split is different: one ball is generally mounted, and certainly, can only be in the form of a fixed ball valve (which might not be floating ball.). The advantage of this form is that the club is integral, with no stem ejection, no backlash, accurate drive, good rigidity and good assembly accuracy. The disadvantage is that the blank cost is high, processing equipment requirements. Generally speaking, one ball open ball valve is much more expensive.

1, the ball valve stem and sphere made of a whole, there is a certain degree of difficulty, and now basically did not do so. This is determined by the form of the structure.2, from the valve structure diagram can be seen below, if the stem and the ball valve as a whole closure, the closure assembly into the valve body, the valve structure must be more complex, to increase the new door rod sealing parts, the processing requirements are higher.

Top mounted ball valve. The stem is joined to the sphere.
