Abstract
The utility model relates to a shock attenuation valve rod, including shell, disk seat and valve rod, the disk seat is installed inside the shell, valve rod one end is connected on the disk seat, and the other end stretches out the shell, the welding of valve rod bottom has the stopper, the stopper sets up in the disk seat, can follow the disk seat inner wall and remove, be equipped with damping spring between stopper and the disk seat, still be equipped with the guide post between disk seat and the shell, the stopper can remove along the guide post, still be equipped with wear pad between valve rod and the disk seat, the utility model discloses the scheme is through installing the disk seat inside the shell, and valve rod one end is connected on the disk seat, and the other end stretches out the shell, and the welding of valve rod bottom has the stopper, is equipped with damping spring between stopper and the disk seat, and during the use, when the valve rod atress, the decompression is slowed down via damping spring to be stressed, and the valve rod vibrations buffering power of unloading guarantees that the disk seat cushions, great improvement the life of valve rod.
Description
Technical field
The utility model relates to a kind of damping valve rod, belongs to plate valve technical field.
Background technique
Plate valve flashboard is pushed to outlet valve valve seat realization sealing by the pressure of valve inlet place medium, so firmly fasten plate valve not only can not play good seal action, on the contrary valve seat and flashboard are damaged to some extent, impact sealing, in using process, the unnecessary vibrations produced greatly reduce working life, and in real work, this phenomenon happens occasionally.
Model utility content
The utility model object provides one can reduce machine vibration to overcome the deficiencies in the prior art, the damping valve rod increased the service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of damping valve rod, comprises shell, valve seat and valve rod; Described valve seat is arranged on enclosure; Described valve rod one end is connected on valve seat, and the other end stretches out shell; Described stem bottom is welded with limiting stopper; Described limiting stopper is arranged in valve seat, can move along valve base inner wall; Damping spring is provided with between described limiting stopper and valve seat; Also directional post is provided with between described valve seat and shell; Described limiting stopper can move along directional post; Also wear-resistant pad is provided with between described valve rod and valve seat.
Preferably, described valve rod is provided with seal ring with the shell place of matching.
Preferably, described shell is made up of alloy.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of damping valve rod of the utility model scheme, by valve seat is arranged on enclosure, valve rod one end is connected on valve seat, and the other end stretches out shell, stem bottom is welded with limiting stopper, damping spring is provided with, during use, when valve rod is stressed between limiting stopper and valve seat, pressure slows down decompression via damping spring, valve rod vibrations buffering unloads power, guarantees that valve seat cushions, improves the working life of valve rod greatly.
