Embodiment
Referring to Fig. 2, a kind of packing seal structure that the utility model embodiment provides comprises: seal arrangement and locking device; Seal arrangement comprises: housing 4, valve rod 8 and filler 7; Locking device comprises: gland 2, depression bar 1 and spring 3;
The inherent structure that valve rod 8 is the palpus seal arrangements such as water pump or valve, offer valve rod hole 14 on gland 2, valve rod 8 through gland 2 and housing 4, is positioned at housing 4 lumen centers successively; Filler 7 is placed in housing 4 inner chambers, is close to housing 4 inwalls and valve rod 8 walls, for filling the gap between valve rod 8 and housing 4, thereby realizes sealing; Spring 3 ring sets, on described valve rod 8, are placed on filler 7, by the compression compression filler 7 of spring 3; Gland 2 is placed on spring 3 and is fastened on housing 4 by depression bar 1; Thereby make filler 7 in stable impaction state.
Referring to Fig. 3 and Fig. 4, gland 2 is fastened on housing 4 by depression bar 1, and in housing 4 outer wall settings, about the centrosymmetric a pair of lug of housing 4, lug is flexibly connected by bearing pin 5 and depression bar 1, and depression bar 1 can rotate around bearing pin 5.Depression bar 1 rotates around bearing pin 5, by the fastening piece that is fixed on end, compresses gland 2.A kind of possibility moulding of the depression bar 1 that the utility model provides, its cross section is L-shaped; Depression bar 1 is around bearing pin 5 rotations, and its fastening piece is placed in the upper surface of gland 2, thus fastening gland 2.
Offer U-groove bevel 13 on the outer wall of gland 2, depression bar 1 rotates and is embedded in U-groove bevel 13, and the other end of depression bar 1 can compress gland 2 by fastening piece.Although fastening gland 2 that can be stable by the fastening piece of the types such as nut, dismounting inconvenience, easily corrosion damages simultaneously; For fear of these problems, preferred, depression bar 1 is divided into pull bar 10 and pressure handle 9; Wherein an end of pull bar 10 is offered pin-and-hole 11 for being movably connected by bearing pin 5 and lug; The other end of pull bar 10 and pressure handle 9 middle parts are fixedly linked, and when pull bar 10 rotates and is embedded into U-groove bevel 13 when interior around bearing pin 5, pressure handle 9 will be positioned at gland 2 upper surfaces, thereby, by the moving axially of restriction gland 2, carry out holddown spring 3, and then compress filler 7; The moulding of the depression bar 1 that therefore the utility model provides can also be T shape structure.
Also different according to the flexible early warning amount of the different springs 3 of the Environmental Conditions of seal arrangement, therefore for the ease of the early warning amount of control spring 3; Preferably, pull bar 10 is connected by screw thread with pressure handle 9, as required, and the distance of by rotation pressure handle 9, regulating pressure handle and lug.
When gland 2 sealing, pressure handle 9 is close to the upper surface of gland 2, still, likely because rock or other factors cause the pressure handle 9 even pull bar 10 that slides to break away from U-groove bevels 13, causes seal failure.Therefore, preferred, offer spill indent 12 at the top of gland 2, when pressure handle 9 compresses gland 2, pressure handle 9 is placed in indent 12, prevents that it from rocking, and then strengthens the steadiness compressed.
The utility model has been simplified the compression operation of packing seal structure by offer U-groove bevel and indent on gland; The pressure handle that adjustable stroke is set on depression bar is regulated the degree of compression, guaranteeing that dismounting is simple, in the time of easy to operate, has guaranteed sealing effect; Being used in conjunction with of spring and gland makes the stressed elastic force balance that simultaneously guarantees filler of uniform filling, avoids that the medium-term and long-term filler rigidity of existing seal arrangement is stressed causes its distortion to cause sealing effect to reduce.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
