Figure 9 shows that the sealing device structure of another embodiment of the present invention, seal groove in the present embodiment is circular arc seal groove 43, O-ring seals 2 is provided with in circular arc seal groove 43, semicircle sulculus 6 is provided with bottom circular arc seal groove 43, the diameter d 2 of circular arc seal groove 43 is 0.5-1.2 times of O-ring seals 2 diameter of section d1, and the diameter d 3 of semicircle sulculus 6 is 0.1-0.4 times of O-ring seals diameter of section d1.、
Semicircle sulculus 6 plays the effect of release O-ring seals 2 Partial shrinkage amount, and stress is discharged, thus makes installation easier, also improves sealability simultaneously.
In above-described embodiment two-seven, the structure be not described is identical with the structure in embodiment one, repeats no more here.
The schematic diagram that Figure 10 shows that seal arrangement of the present invention is actual when using, for the structure of seal arrangement in embodiment one, during use, seal arrangement is arranged between sealing seat 3 and running shaft 4, the other end is fixed by gland 5, owing to adopting the design of multiple-sealed tooth 15, every tooth 15 of sealing together just forms effective sealing together, single seal arrangement is so just made to be provided with the identical sealing effect of multiple-sealed performance, therefore sealability is splendid, a certain amount of Lubricants can be stored in the groove formed between adjacent seals tooth 15, reduce surface friction drag, extend the operating life of seal arrangement.
Elastomer 2 forms magnitude of interference when initial installation, and the radial force therefore produced increases sealing tooth 15 and the contact stress between sealing seat 3 and running shaft 4, further increases sealability; Under the effect of hydrodynamic pressure P, the enclasping force of sealing tooth 15 increases, and sealability is better.
After seal ring 1 long-term work forms wearing and tearing, the magnitude of interference of elastomer 2 is discharged, and plays wear compensation effect, and thus sealing device has the ability of auto-compensation, substantially increases the operating life of seal arrangement.
Because elastomer 2 is surrounded protection by seal 1, under high pressure can not " be extruded ", therefore sealing device also has splendid voltage endurance capability.
In order to reach the optimum efficiency of sealing and lubricity, the height design of sealing tooth 15 can be ladder downward trend along the direction of hydrodynamic pressure P, namely, the magnitude of interference of sealing tooth 15 is made to be ladder downward trend along the direction of hydrodynamic pressure P, and by the structure of choose reasonable seal ring 1 and elastomer 2, material and its combination, its performance advantage can be given full play to.
In actual applications, adopt general plug envelope (teflon+stainless steel spring structure) of import can only use 7-10 days in strong acid media, constantly change Sealing; And after adopting seal arrangement of the present invention, reach working life 2-3 month even longer, be the 6-15 of original general plug seal structure doubly, and 1/3 of the price general plug envelope that is import, be that enterprise saves many costs while extending operating life.
The AH630 gas-liquid booster pump product that Shenzhen hydraulic pressure Co., Ltd produces, design system pressure 400MPa, speed 0.06m/s, use medium is water, serviceability temperature is normal temperature, because system pressure is higher, conventional seals product is difficult to be competent at (sealing load of conventional seals product only has 100-200MPa), after adopting high-performance multipurpose dentation Y shape combination sealing arrangement of the present invention, through installation delivery test, sealing device can meet the seal request of AH630 gas-liquid booster pump product completely.
Combination sealing arrangement of the present invention is by seal ring and elastomeric combination and arrange sealing tooth at seal ring outer wall, achieve excellent sealability, there is high pressure resistant, corrosion-resistant, that purposes is wide, the life-span is long feature, decrease the number of times changing Sealing under high pressure, deep-etching working environment, while saving cost of production, improve working efficiency.
The foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; the structure characteristic of the various embodiments described above mutually can combine, replace; form new embodiment; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
