Abstract
The utility model relates to the valve technical field, specifically to a valve with a novel valve stem. The valve stem is designed into a tapered-sectional structure according to stress, so that the section of the valve stem is small on the upper part and large on the lower part. The wall of the valve stem at the joint between the valve stem and a blocking nut is thickened. Moreover, the valve with a novel valve stem is cheap and light.
Description
Technical field
The utility model relates to valve technology field, especially a kind of valve of novel valve rod.
Background technique
The valve field valve rod is that each cross-sectional sizes is identical at present, because the suffered stress intensity of valve rod different cross section is inconsistent, if press the maximum stress design, then makes the valve rod cross section big, and the cost height takes place otherwise stress big position generation distortion, bending phenomenon occur.Valve mass is caused very big influence.
Summary of the invention
The utility model has overcome the prior art deficiency, invented a kind of variable cross section valve rod, by the following technical solutions: a kind of valve of novel valve rod, comprise actuator 1, support 2, valve gap 3, valve rod 4, spool 5, valve body 6, guide cylinder 7, valve seat 8, locking nut 9, the valve of described a kind of novel valve rod, the transmission device of valve rod 4 tops and actuator 1 links, bottom and spool 5 link, because bottom and spool 5 joints, thereby the big stress that produces of moment of torsion is big, so it is big with respect to cross section, valve rod 4 top in guide cylinder 7 following position sectional dimensions, simultaneously at valve rod 4 and locking nut 9 joint increased diameter and wall thickness, thereby both guaranteed that valve rod satisfied usage requirement, and reduced the material consumption of valve rod again and played the purpose of weight reduction.

Embodiment
As shown in the figure, a kind of valve of novel valve rod, the transmission device of valve rod 4 tops and actuator 1 links, bottom and spool 5 link, because bottom and spool 5 joints, thereby the big stress that produces of moment of torsion is big, so it is big with respect to cross section, valve rod 4 top in guide cylinder 7 following position sectional dimensions, simultaneously, guarantee that valve rod satisfies usage requirement, reduced the material consumption of valve rod and played the purpose of weight reduction at valve rod 4 and locking nut 9 joint increased diameter and wall thickness.
Claims (1)
1. the valve of a novel valve rod, be provided with actuator, support, valve gap, valve rod, spool, valve body, guide cylinder, valve seat, locking nut, it is characterized in that valve rod is big with respect to cross section, valve rod top in the following position of guide cylinder sectional dimension, described valve rod link to each other with locking nut position increased diameter and wall thickness.
