Based on this basic structure, the utility model can also be made following optimization and limit:
Further, a side length direction of groove 91 of the present utility model is provided with elastic force scale value.
Further, connector 7 of the present utility model is preferably pin.
Further, connector 7 of the present utility model is processed with pointer with one end that groove 91 coordinates, and usesIn instruction elastic force scale value.
Further, the inner ring of bearing 4 of the present utility model is by being arranged on the nut 3 at rotating shaft 6 topsCompress, the outer ring of described bearing 4 compresses by the gland 5 being fixedly connected with bearing block 2.
Further, flexible member 8 of the present utility model can be spring or bellows.
Further, the outside of the utility model adapter 10 small ends 102 is also provided with protective sleeve 11,Can prevent that adapter 10 from producing frictionally damage to sealing ring.
Further, the material of protective sleeve 11 of the present utility model is F4, and this kind of material is convenient to processing,And can avoid well sealing ring to produce damage.
Compared with prior art, advantage is the utility model:
1, the utility model provides a kind of seal face grinding ratio pressure regulator, have continuously adjustable,Advantage easy to adjust.
2, the utility model is simple in structure, easy to use.
3, the utility model can clearly show specific pressure value.
4, the utility model long service life.
