Purpose of the utility model is realized as follows:
A kind of device reducing motor-driven valve sealing axis frictional resistance, the sealing shaft flange lid including being provided with flange bolt 8
9, and be arranged under the motor-driven valve at sealing 9 center of shaft flange lid and seal axis 7, it is characterised in that: the sealing shaft flange lid 9
Bottom slot, and it is provided with graphite packing packing layer 1, sliding bearing 2 is equipped with above graphite packing packing layer 1；The sliding
It is provided with plane bearing 4 above bearing 2, graphite-seal ring 10 is provided on plane bearing 4, is provided with above graphite-seal ring 10
Bearing cap sealing surface 6；
Plane bearing upper end cover 5 is provided with above the plane bearing 4, lower section is provided with plane bearing lower cover 3；
The plane bearing upper end cover 5 is between graphite-seal ring 10 and plane bearing 2；Under the plane bearing
End cap 3 is arranged between sliding bearing 2 and plane bearing 4；
The 9 bottom slot ruler diameter of sealing shaft flange lid determines that graphite packing padding must according to bearing ruler diameter and height
Compression must be filled up, top graphite-seal ring 10 is concordant with bearing cap sealing surface 6；
The sliding bearing 2 is adjacent under sealing axis motor-driven valve and seals axis 7；
Plane bearing lower cover 3, plane bearing 4 and the plane bearing upper end cover 5 is successively to compress installation knot
Structure；
Metal wound gasket is added on the bearing cap sealing surface 6；
The 6 tick slot depth of bearing cap sealing surface is less than using metal wound gasket thickness.
Positive beneficial effect: the utility model is that a kind of structure is simple, convenient to install and maintain, and can be effectively reduced electronic
Valve seal axis friction, reduce motor-driven valve torque, can effectively prevent and reduces apparatus body corrosion, reduce maintenance of equipment expense with
Valve investment avoids having an impact system operation, also improves the competitiveness of enterprise.
