Description
Technical field
The utility model belongs to the sealing ring installing area of combination sealing, relates to the close of a kind of built-up pistonSeal ring apparatus for shaping.
Background technology
For needing hydraulic system that the device of power is provided, very high to sealing requirements, sealing is to preventThe effective way of revealing, sealed medium passes through close with the form of leakage, seepage, diffusion oftenSealing is revealed. Existing hermetically-sealed construction adopts traditional O type circle to add back-up ring form always, not yet sets foot inThis type of combination sealing form; For the sealing of stiffening device, can also adopt built-up piston sealing,Sealing device adopts the double acting structure with O RunddichtringO, and material is No. 55 composites, this materialMaterial possesses very high functional reliability and shape stability and good sliding capability and very high chemistryStability and thermally-stabilised; But the sealing ring of sealing device, in the time installing, easily causes damage.
Utility model content
The purpose of this utility model is to provide a kind of sealing ring apparatus for shaping of built-up piston, solves sealingRing easily causes the problem of damage in the time installing.
The technical solution of the utility model is: a kind of sealing ring apparatus for shaping of built-up piston, its featureBe: comprise fairlead 1 and shaping cover 2; The front portion of fairlead 1 is the cylinder with inner chamber,The external diameter of its internal diameter and piston matches, and the rear portion of fairlead 1 is cone, and fairlead is with inner chamberOne end be enclosed within the end of piston 3; Shaping is overlapped 2 front portions and is provided with two stepped holes, and 2 front ends are overlapped in shapingThe internal diameter in first step hole and the external diameter of sealing ring match, the external diameter of second step hole and fairleadMatch; It is the conical bore expanding outwardly that 2 rear end endoporus are overlapped in shaping, the smallest end internal diameter of conical bore withThe external diameter of sealing ring matches, for the shaping of sealing ring.
Beneficial effect: the utility model can carry out sealing ring shaping intact assembling, simple in structure,Operating maintenance is convenient, time saving and energy saving, has improved assembly quality.

Detailed description of the invention
For making the purpose of this utility model, content and advantage clearer, below in conjunction with accompanying drawing and realityExecute example, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of sealing ring apparatus for shaping of built-up piston, comprises and leadingTo cover 1 and shaping cover 2; Fairlead and shaping cover are used in combination fitting tight ring; As shown in Figure 2, guidingThe front portion of cover 1 is the cylinder with inner chamber, and rear portion is cone, and fairlead is with one end cover of inner chamberIn the end of piston 3; As shown in Figure 3, shaping is overlapped 2 front portions and is provided with two stepped holes, and 2 front ends are overlapped in shapingThe internal diameter in first step hole and the external diameter of sealing ring match, the external diameter of second step hole and fairleadMatch; It is the conical bore expanding outwardly that 2 rear end endoporus are overlapped in shaping, the smallest end internal diameter of conical bore and closeThe external diameter of seal ring matches, for the shaping of sealing ring.
As shown in Figure 1,3, in assembling process, sealing ring must be placed on to 8min in boiling water, closeSeal ring is set to the face of cylinder of fairlead from the taper seat of fairlead; Shaping cover 2 is enclosed within outside fairlead, leadsFront end face to cover aligns with the initiating terminal of the ditch shape groove of the installation sealing ring of piston, and shaping is overlapped 2 front ends and pushed awayRotary packing ring moves forward in the ditch shape groove of piston. In the process of promotion sealing ring, shaping cover is rightSealing ring plays shaping operation; After sealing ring installation, shaping cover can be enclosed within to work converselyBe rotated gently beyond the Great Wall, as shown in Figure 5, the outer surface of sealing ring carried out to shaping and static recovery,Be not less than 20min static recovery time.
Use the utility model can guarantee to be pressed in the sealed groove of piston harmless sealing ring, thenSealing ring is carried out to shaping, make sealing ring end-state realize set objective, meet the demands.
