Abstract
Disclosed is a sleeve combined seal element which belongs to the packing seal technical field. The seal element is mainly composed of a tensional spring forcing element (3) and a sleeve piece (4); the sleeve piece (4) is nested on the sealed surface; the tensional spring forcing element (3) used for transferring torque is nested on the other lateral surface of the sleeve piece (4); the sleeve piece (4) has radial deformation along with the radial displacement of the tensional forcing element (3) and implements the radial displacement element used for the axial end surface static seal through a pressing mechanism and a pressing sleeve (5) used for transferring torque. The sleeve combined seal element not only can solve the uneven radial pressure of the packing seal, but also can further improve the seal capacity of the seal element through adjusting the radial seal pressure and the radial seal gap; meanwhile, the functions of enabling the radial seal to be in the best state, no leakage in the axial end surface seal and the comprehensive combination seal technology are realized.
Description
Technical field
The utility model belongs to the packing seal technical field.
Background technique
Traditional packing seal is that the filler made from soft materials such as fiber crops, leather, asbestos, expanded graphites stops up sealed axle and stuffing box, or the gap between housing bore and the bar and stop the sealing technique of dielectric leakage.But because the packing seal texture material is soft, compactness is poor, adds only to depend on axial compression to produce radial seal pressure inequality, influences sealing effect and sealability.Glais ring, this special envelope waits the co-axial seal reliable performance, and effect is remarkable.But also there is inconvenience to regulate the deficiency of its radial seal pressure.
Summary of the invention
The utility model adopts intensity bigger, hardness is higher, more withstand voltage, wear-resisting, media-resistant, heat-resisting, from the better sealing material of sliding performance, (as: strengthen the engineering plastics and the alloys thereof such as teflon of modification, the various alloys of various impregnated materials of graphite etc.) combine with existing sealing technique, purpose is to provide a kind of sleeve type combined sealing component, this element not only can solve the problem of packing seal radial pressure inequality, and by regulating radial seal pressure, or the radial seal gap further improves the sealability of seal element, can keep radial seal to be in the optimum state simultaneously, the axial end static seal is leak free multi-functional, comprehensive combination sealing technology.
Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:
A kind of sleeve type combined sealing component, it mainly is made up of afterburning element 3 of torsional spring type and sleeve member 4, said sleeve member 4 is sleeved on sealed, but the afterburning element 3 of the torsional spring type of said transmitting torque be sleeved on the another side of sleeve member 4, sleeve member 4 is the radially variable bit unit.
Described sleeve type combined sealing component, it is characterized in that said sleeve member 4 can with other Sealing fitted seal.
The utility model can be used as seal element and produces series product, and utilizes the utility model can develop new products such as oil gas cylinder, plunger, plunger pump, various pipe joints.

Embodiment
The utility model is had many uses, and now only proposes four kinds of embodiments.
1, about the sealing of running shaft.
2, the sealing of reciprocating shaft.
3, the sealing in to-and-fro motion hole.
4, the principle assumption diagram of another kind of rotation axis seal.
The utility model mainly when utilizing torsion spring to be subjected to moment of torsion its diameter contract and be subjected to and spring spiral in the same way during moment of torsion, or expand when being subjected to oppositely to turn round with the spring rotation direction characteristic and be designed to, be similar to the afterburning element of torsional spring type of torsion spring and be combined in shaft sealing in the afterburning element of torsional spring type with or the sleeve member formation of outer hole sealing usefulness.
The afterburning element of torsional spring type preferably adopts rectangle or trapezoidal Spring Steel Wire, two end part are designed to have inner arm, radially outer arm, axial outer arm, spill, convex structure, and shaft sealing should have certain clearance with the afterburning element of torsional spring type, in when, with compensation compression deformation taking place, the afterburning element axial length of torsional spring type increment.
Be combined in the afterburning element of torsional spring type or outer sleeve member, be higher with a kind of hardness, intensity quality seal material big, that Young's modulus is bigger is made or preceding a kind of material and material very big with another kind of intensity, that Young's modulus is enough big are made and can be born the also compound or sleeve member that combines of the compression-member of energy radial shift (as have uniform axial groove, open uniform lobe, open structure such as uniform part mouth) of bigger thrust load.Be designed to leave the gap with sealed axle or hole, and the garden cylindricality is arranged, corrugated, cydariform, shape of a saddle etc., or can with the radial sealing surfaces structure of the combined coupling of other Sealings and axial static seal end face with plane, the garden conical surface, garden arc shaped surface, B shape face, concave surface, convex surface, preceding several mutual composite structures, or can with the sleeve member of the combined matching structure of existing Sealing.
When utilizing sleeve type combined sealing component to implement sealing, according to (from nearly side medium) fixed cover, sleeve type combined sealing component, but the clamping sleeve of transmitting torque, but the order of hold-down mechanism can be the clamping sleeve of transmitting torque and fixed cover transposing order according to the sealing needs, be assembled in axle with or the hole use in the seal arrangement.But but the clamping sleeve of fixed cover and transmitting torque all has the be complementary structure of transmitting torque of the axial static seal end-face structure that is complementary with sleeve member and the afterburning element of torsional spring type two ends arm, but clamping sleeve also has the Baltimore groove of transmitting torque, structures such as hole, but and it is fixing respectively or be stuck in the clamping sleeve of fixed cover and input torque the afterburning element of torsional spring type two ends arm
During debugging, but at first to seal the moment of torsion of required rotation direction to the clamping sleeve input of transmitting torque, and radial pressure by producing by the afterburning element of torsional spring type, force and be combined in when axle is close in the afterburning element of torsional spring type or the sleeve member diameter the during sealing of outer hole contracts that shaft sealing is used or the hole of expanding seals the elasto plastic deformation of usefulness, to regulate radial pressure contact seal or the sealing of radial clearance non-contact gap that sealing is paid, make radial seal be in the optimal seal state earlier, and when keeping this optimum state, guarantee that with hold-down mechanism the axial end static seal does not have leakage, lock this optimal seal state at last.Add and take break-in, cooling or measure such as lubricated, further improve its sealability.
In the utility model, be assembled in the sleeve member or the afterburning element of outer torsional spring type only is subjected to radial pressure and load not to bear thrust load.
Fixed cover can be integral with the supporting member of sealed axle, can be according to the welding of sealing needs, bonding, interference assembling, or screw is when adding Sealing and fixing shaft sealing, or become one with the bar such as the piston rod of hole sealing usefulness, or available pin, screw be secured on the bar, bears the moment of torsion from the afterburning element of torsional spring type.
Be combined in the afterburning element of torsional spring type in the utility model or outer sleeve member is a core component of the present utility model, it promptly is a Sealing, is again and the carrier of other Sealings of its combination, has functions such as location, guiding again.
