Embodiment
As shown in Figure 1, the bar 10 of water tap (not shown) comprises the outer body of rod 12 and extends axially axostylus axostyle 14.The lower end 16 of the outer body of rod 12 is provided with the outside thread that screws in the faucet body (not shown).First end 18 of axostylus axostyle 14 the most close lower ends 16 is provided with increased diameter head 20.Second opposed end 22 is provided with a plurality of longitudinal extension ribs 24 that separate along circumference on the axostylus axostyle 14.By screw 28 wafer type packing ring 26 is connected on the head 20.The handle (not shown) connects the rib 24 of second end 22, so that along clockwise or the manual rotary shaft 14 of counterclockwise direction, thereby open and close water tap.
Fig. 2 represents the embodiment of gasket assembly 30 of the present invention and typical water tap inserting member 32.The shape of inserting member 32 is short cylindrical shape pipe 34, and the excircle of pipe 34 is provided with the flange 36 that extends radially outward near upper end.Stopper 38 with smooth curved or curved upper surface 40 is extended upward vertically by flange 36.Form shoulder 42 on pipe 34 excircles between flange 36 and the stopper 38.
In order to close the water tap that adopts prior art packing ring 26 shown in Figure 1, be rotated in a clockwise direction axostylus axostyle 14, with packing ring 26 by on the upper surface 40 that is pressed in stopper 38.When contacting fully between the surface of packing ring 26 and the upper surface 40, form sealing and prevent that water from flowing through the central passage of inserting member 32, therefore water tap is closed.If continue to be rotated in a clockwise direction axostylus axostyle 14, then packing ring 26 more pushes hard the packing ring 26, the particularly anchor ring of packing ring 26 that further compresses by stopper 38 between stopper 38 and the head 20.Suppose that packing ring 26 does not break or lost efficacy, then limit water tap and close the compressibility that the factor of power is a packing ring 26.That is, as the people of rotary shaft 14 further during compression washer 26, then axostylus axostyle 14 promptly stops for closing turning clockwise that water tap carries out.Certainly these can be different and different according to everyone muscle power.
The outer rigid housing 46 that comprises elastomer seal 44 and arrangement elastomer seal 44 according to the gasket assembly 30 of the embodiment of the invention.Elastomer seal 44 has cylindrical wall 48 and first wall 50, cylindrical wall 48 has first axial end 49 and the second relative axial end 51, first wall 50 is radially extended internally by first axial end 49, forms the cavity 52 that liquid is flowed into by second axial end 51 with cylindrical wall 48.Shell 46 have bottom 54 and the skirt section 56 of extending vertically by the bottom to form a seat.The interior shape of shell 46 (i.e. Zuo shape) adapts to the external shape of elastomer seal 44.Skirt section 56 extends across second axial end 51 of cylindrical wall 48 vertically, ends at anchor ring 53, and the external diameter of the internal diameter of anchor ring 53 and elastomer seal 44 second axial ends 51 has common radially end points.As shown in Figure 3, when forcing or promoting gasket assembly 30 and at utmost lean against on the inserting member 32, skirt section 56 is in abutting connection with flange 36 and seating shoulder 42, the disconnection fully or the closed condition of corresponding water tap.
Elastomer seal 44 comprises antelabium or barrier film 58, and it crosses second axial end 51 and radially extends internally towards the hole 60 that liquid flows into cavity 52.Antelabium or barrier film 58 work with first wall 50 and cylindrical wall 48 and form circumferential groove 62 on Sealing 44 inboards.Groove 62 has two kinds of effects.The first, it provides and can apply hydraulic pressure and make antelabium (barrier film) 58 of elastomer seal 44 and adjacent portion by the outside zones of distortion of cavity 52.In this way, coming in the pass closed procedure that carries out on the stopper 38 by antelabium 58 and the adjacent portion that forces elastomer seal, hydraulic pressure itself helps the formation that seals.The another kind effect of groove 62 is that when more firmly being pushed against gasket assembly on the inserting member 32, it makes antelabium 58 and cylindrical wall 48 be tending towards reducing the size of groove 62 to enterolithic degree along diagonal.This is of value to the elasticity that enhancing itself has the elastomer seal 44 of natural elasticity.
First wall 50 and bottom 54 have the corresponding axial bore 64 and 66 of mutual aligning.When gasket assembly 30 used with bar 10, screw 28 passed hole 64,66, thereby gasket assembly 30 was fastened on the head 20 of axostylus axostyle 14.
54 inside, bottom is provided with around the hole 66 protrusion spine 68.First wall 50 has a thinning part 70, and this thinning part covers in spine 68.When screw 28 was fastened on gasket assembly 30 on the axostylus axostyle 14, the head of screw 28 was clamped in thinning part 70 in the spine 68.This helps elastomer seal 44 is fixed in the shell 46.But the elastomer seal 44 main press fits that form by the relative size of these parts are fixed in the shell 46.
The operation of gasket assembly 30 is described below.Reequip gasket assembly 30 by unscrewing screw 28, unload the disc washer 26 of prior art routine, make the shaft of screw 28 pass hole 64 and 66, then screw 28 is screwed in the head 20 of axostylus axostyle 14.Suppose the water tap connection, make water upwards flow through inserting member 32.In order to close water tap, be rotated in a clockwise direction axostylus axostyle 14.This moves down axostylus axostyle 14 vertically, and gasket assembly 30 is moved towards inserting member 32.When proceeding this and move, second axial end 51 of elastomer seal begins to contact the upper surface 40 of stopper 38.This has formed the initial off point of water tap.But some liquid also can be owing to hydraulic pressure flows through water tap.In order to close water tap fully, axostylus axostyle 14 further is rotated in a clockwise direction.As a result, by stopper 38 pressure elasticity Sealings 44.In addition, the antelabium 58 of elastomer seal and adjacent portion can form groove 62 thereby push along diagonal to internal strain.Simultaneously, in the cavity 52 and the hydraulic pressure of effect in the groove 62 with counterproductive, and be tending towards antelabium 58 is pushed against on the stopper 38.Therefore, by acting on the hydraulic pressure enhanced leaktightness effect in the elastomer seal 44.At last, when the people continued rotary shaft 14 along clockwise direction, skirt section 56 is the flange 36 of its anchor ring 53 contact seatings in shoulder 42 particularly.This has limited the downward vertically motion of gasket assembly 30.If someone attempts further to be rotated in a clockwise direction axostylus axostyle 14, then extra power is applied on the shell 46, prevents that elastomer seal 44 is subjected to excessive shearing force/tear edge.
Shell can be made by plastic materials such as acetal (ACETAL).But as selection, shell also can be made by metal or alloy, includes but not limited to brass.Elastomer seal 44 is made relatively good by rubber material, be that the rubber material of 60-100 is made by the shore hardness scope preferably.A kind of material of particularly suitable is a peace (SANTOPRENE) in the Top of Soviet Union.
Be apparent to those skilled in the art, in the scope of the invention that is limited by above-mentioned explanation and following claim, can carry out various modifications and change the foregoing description.
