Select seal ring material must possess enough intensity, hardness, wear resistance, corrosion resistance, temperature tolerance, shock-resistant toughness and fatigue strength etc., and to have good processability and rational Economy.Wherein, wear resistance, corrosion resistance and heat crack resistance are topmost requirements.
The structural type of seal ring is a lot, mainly determines according to usage requirement.What have is simple in structure, but sealing effect is undesirable.The complex structure that has has increased manufacture difficulty.And, in order to reach good sealing effect, have to sacrifice the working life of seal ring.
As: common rubber o-ring seal ring Applicable temperature is-45～+ 180 ℃, is not suitable for containing the particulate matter occasion; Graphite-seal ring is applicable to static seal more, does not contain the particulate matter occasion, and level can not satisfy axial motive sealing at present; Metal C type ring complex process, mould is expensive, requires the element precision height, is difficult to reach requirement.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of prior art, and a kind of eyes type seal ring is provided, and the seal ring ring body adopts metal material, can be under-196 ℃～+ 750 ℃ temperature and contain in the environment of particulate matter and use.Sealed material sealing effects such as the inner all right horsestone China ink of eyes type, tetrafluoro more.This structure make and processing technology all very simple, cost is low, itself has compensatoryly, improve working life greatly.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of eyes type of the utility model seal ring, comprise the seal ring ring body, described ring body is made of upper ledge and lower frame, and upper and lower frame is a symplex structure, upper ledge covers on the lower frame rhombus framework of the direction sealing of arching upward up and down respectively that forms a symmetry, is a cavity between the upper and lower frame.Upper and lower frame described in the utility model is the metallic material manufacturing.
Be provided with tetrafluoro circle or graphite circle in the cavity between the upper and lower frame described in the utility model.
Upper and lower frame described in the utility model joint is provided with tetrafluoro circle or graphite circle.
The utility model discloses a kind of sealing configuration that described eyes type seal ring is installed simultaneously, described sealing configuration comprises central shaft, central axle sleeve is equipped with limited ring, described limited ring is provided with a circle groove near the central shaft position, one circle eyes type seal ring is installed in the groove, be with a circle trim ring on the eyes type seal ring, described eyes type seal ring comprises the seal ring ring body, described ring body is made of upper ledge and lower frame, on, lower frame is a symplex structure, upper ledge covers and forms making progress respectively of a symmetry on the lower frame, the rhombus framework of the sealing that lower direction arches upward, on, it between the lower frame cavity.
The utility model adopts metal to do the seal ring ring body, improves serviceability temperature and life-span; And upper and lower socket of the eye adopts die stamping, good springiness, and technology is simple.
The utility model to being stuck, solves the complexity of compensation and technology by upper and lower framework; The utlity model has the elastic compensating socket of the eye body structure of optimization, power suffered when axle moves up and down is very little, has reduced the friction between axle and seal ring, increases the service life.
Be provided with tetrafluoro circle or graphite circle in the cavity between the upper and lower frame described in the utility model, increase elasticity.
The upper and lower frame of the utility model seal ring joint is provided with graphite circle or tetrafluoro circle, improves sealing effect.
The cut-out control that the utility model is applicable to high temperature, high pressure, corrosion protection and contains the various fluids of impurity such as solid particulate matter, slurry, fiber.
The sealing configuration that described eyes type seal ring is installed described in the utility model, trim ring is fixed on eyes type seal ring in the groove of position limit cycle, applying suitable pressure makes eyes type seal ring produce distortion, make it be close to axle and position limit cycle groove, seal ring and between centers have the tight power of certain desire when axle moves up and down, and make it reach sealing.
