Description
Technical field
The utility model relates to a kind of valve stem spacing structure, 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, some producer is poisoning dated at product descritption, this valve closes on earth refunds 1/4 or 1/2 again, but misoperation phenomenon still happens occasionally in practical operation.
Model utility content
The utility model object provides a kind of valve stem spacing structure extending valve working life to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of valve stem spacing structure, comprises valve body, valve seat, valve rod and flashboard; Described valve body and valve seat fixedly mount; Described valve rod is arranged in valve body; Described stem bottom is welded with limiting stopper; Described flashboard is welded on limiting stopper other end; Wear-resistant pad is provided with between described limiting stopper and valve body; Described flashboard is arranged between valve body part and limiting stopper and is provided with spring.
Preferably, described flashboard is provided with lubrication groove with the valve seat place of matching.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of valve stem spacing structure of the utility model scheme, by at stem bottom welded limiting block with flashboard is welded on limiting stopper other end, wear-resistant pad is provided with between limiting stopper and valve body, be arranged between valve body part and limiting stopper at flashboard and be provided with spring, when valve pass puts in place, limiting stopper top is on valve body, spring is played a supporting role, flashboard cannot be continued descending, avoid the conflict of power between valve rod and flashboard, ensure that the normal use of valve, decrease the damage of misoperation to valve seat and flashboard.
Accompanying drawing explanation
