Abstract
The utility model relates to a valve shaft support sleeve for a valve. The valve shaft support sleeve comprises a bearing cover, a bearing support and a self-aligning ball bearing, wherein the self-aligning ball bearing is embedded in the bearing support, the bearing cover is butted against the self-aligning ball bearing and is connected with the bearing support through a screw bolt, and the inner diameter of the self-aligning ball bearing is matched with the outer diameter of the end part of a valve shaft. The valve shaft support sleeve has the advantages that the self-aligning ball bearing is adopted, the grinding between the valve shaft and the valve shaft support sleeve is avoided, the damage to the valve shaft is reduced, and the service life of the valve shaft is prolonged.
Description
Technical field
The utility model relates to a kind of valve shaft supporting sleeve for valve.
Background technique
Common valve generally includes valve body, valve plate, valve shaft, valve shaft supporting sleeve, valve shaft gland etc.Valve plate is arranged on valve shaft, and valve shaft supporting sleeve is arranged on valve body, and valve shaft is connected with valve shaft supporting sleeve, causes valve shaft to drive valve plate, and valve opening and closing is flexible.
See Fig. 1, existing valvular valve shaft is directly installed in valve shaft supporting sleeve, and valve is stopped by external force when work, valve shaft directly grinds valve shaft supporting sleeve, opens and closes and has resistance, works long hours and there will be valve shaft, supporting sleeve wear phenomenon, valve shaft distortion when serious, valve cannot be opened.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of valve shaft supporting sleeve for valve, realizes in the situation that not damaging valve shaft and valve shaft supporting sleeve, and valve opens and closes flexibly, and extends the working life of valve shaft supporting sleeve.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of valve shaft supporting sleeve for valve, comprise bearing cap, bearings, selfaligning ball bearing, selfaligning ball bearing embeds in bearings, and bearing cap is resisted against on selfaligning ball bearing, and be bolted with bearings, described selfaligning ball bearing internal diameter and valve shaft outer end diameter match.
Compared with prior art, the beneficial effects of the utility model are:
Adopt selfaligning ball bearing, avoid grinding between valve shaft and valve shaft supporting sleeve, reduce valve shaft damage, extend the working life of valve shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of original supporting sleeve.
Fig. 2 is structural representation of the present utility model.
In figure: the original supporting sleeve of the 1-valve shaft 2-selfaligning ball bearing 3-bearings 4-original valve shaft 6-of bearing cap 5-.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 2, for the valve shaft supporting sleeve of valve, comprise bearing cap 4, bearings 3, selfaligning ball bearing 2, selfaligning ball bearing 2 embeds in bearings 3, bearing cap 4 is resisted against on selfaligning ball bearing 2, and be bolted with bearings 3, described selfaligning ball bearing 2 internal diameters and valve shaft 1 outer end diameter match.
In valve shaft supporting sleeve, increase by a selfaligning ball bearing 2, selfaligning ball bearing 2 internal diameters and valve shaft 1 end drive fit, increase selfaligning ball bearing 2 valve rotated freely, and valve opening and closing is flexible, there will not be valve shaft 1, the wearing and tearing of valve shaft supporting sleeve and damage phenomenon.
When being applied to some valvelets, can adopt deep groove ball bearing to replace selfaligning ball bearing 2.
The utility model adopts selfaligning ball bearing, avoids grinding between valve shaft and valve shaft supporting sleeve, reduces valve shaft damage, has extended the working life of valve, has improved the performance accuracy of valve.
