Description
Technical field
The utility model relates to a kind of double eccentric butterfly valve, is specially double eccentric butterfly valve valve rod regulation structure, belongs to the throttle valve technology field.
Background technique
At present, existing pair of eccentric butterfly valve, in its valve rod regulation structure, shaft length leaves surplus, needs repair again when assembling, and more loaded down with trivial details, precision is not high yet, so be necessary to improve.
Summary of the invention
The utility model provides a kind of double eccentric butterfly valve valve rod regulation structure at the problem that prior art exists, and this structure can be finely tuned in assembly process, is suitable for assembling, and can simplifies maintenance.
The purpose of this utility model realizes by following measure:
A kind of double eccentric butterfly valve valve rod regulation structure, it comprises valve body, valve plate, Sealing and upper and lower valve rod, and upper and lower copper sheathing, described upper and lower valve rod is set in valve body and valve plate both sides cooperation position, it is characterized in that: described lower valve rod outer end also is provided with a lower cover, fixedly connected with valve body on this lower cover and offset with lower valve rod, this lower cover outer end is provided with a groove, the center is provided with screw, one stud is assemblied in this screw, the inner end of this double threaded screw is relative with lower valve rod one end, the outer end interior angle nut that also is connected.
Be provided with a steel ball between described double threaded screw and the lower valve rod, and this steel ball places the screw front end of lower cover.
Also be installed with an anti-loosening nut on the described stud.
Described lower cover outer end also is pressed with a vinyl cover.
The utility model has following advantage compared to existing technology:
Bigbore butterfly valve is owing to self weighs greatly, and possibility valve plate equipment is not in place during assembling, in stem bottom, the free adjustment structure is housed, and can realize finely tuning when device.This double eccentric butterfly valve valve rod regulation structure is by being equipped with the controlling device that hardened steel ball connects stud in lower valve rod bottom, in assembling or when using later on, can the free adjustment stem position, and to reach designing requirement.Can finely tune in the assembly process, be suitable for assembling, maintenance is simplified, and prolongation in working life (point contacts with face, and frictional force is little) is economic and practical.
