Abstract
The utility model provides a kind of low temperature spring energy-storage sealing ring, including sealed outer ring and the metal O-ring being arranged in sealed outer ring, the cross section of the sealed outer ring is U-shaped, with two pincers portions in forked, the caulking groove being open on the outside of radially is formed between the opposite side in described two pincers portions, the metal O-ring is embedded in the caulking groove of the sealed outer ring；The opposite side surfaces in two pincers portions of the sealed outer ring respectively along the metal O-ring it is circumferential at there are one or several annular grooves.Low temperature spring energy-storage sealing ring is after squeezing stress, the both sides of the annular groove respectively form a layer sealing surface after squeezing stress, to form multi-stage sealed effect, reduce influence of the microcosmic irregularity degree of valve body, valve seat sealing surface to valve seal performance, extend its sealing performance and service life, is also provided with better wiping ability.
Description
Technical field
The utility model is related to a kind of sealing rings, more particularly to low temperature spring energy-storage sealing ring.
Background technology
Shown in Figure 1, conventional springs accumulation of energy sealing ring sealing surfaces are smooth, lean on elastic potential energy and pressure energized seal,
Its narrow seal face, which is once worn, will lose sealing function.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of low temperature spring energy-storages simple in structure, sealing effect is good
Sealing ring.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
A kind of low temperature spring energy-storage sealing ring, including sealed outer ring and the metal O-ring that is arranged in sealed outer ring, it is described
The cross section of sealed outer ring is U-shaped, has two pincers portions in forked, opening is formed between the opposite side in described two pincers portions
Radially the caulking groove in outside, the metal O-ring are embedded in the caulking groove of the sealed outer ring；It is characterized in that：
The opposite side surfaces in two pincers portions of the sealed outer ring respectively along the metal O-ring it is circumferential at there are one or
Several annular grooves.
Wherein：The inner surface of the caulking groove is shiny surface.
Wherein：The metal O-ring is rolled by double-layer alloy steel band.
Compared with prior art, it is had the advantage that using the utility model of above-mentioned technical proposal：Low temperature spring
For accumulation of energy sealing ring after squeezing stress, the both sides of the annular groove respectively form a layer sealing surface after squeezing stress, more to be formed
Grade sealing effect, reduces influence of the microcosmic irregularity degree of valve body, valve seat sealing surface to valve seal performance, extends its sealing
Performance and service life are also provided with better wiping ability.
Description of the drawings
Fig. 1 is sectional view of the conventional springs accumulation of energy sealing ring when being pressurized in squeezing space；
Fig. 2 is sectional view of the utility model low temperature spring energy-storage sealing ring when being pressurized in squeezing space.
Reference sign：10- sealed outer rings；11- caulking grooves；20- metal O-rings；30- annular grooves；31- sealing surfaces.
Specific implementation mode
Shown in Figure 2, the utility model provides a kind of low temperature spring energy-storage sealing ring, including sealed outer ring 10 and setting
Metal O-ring 20 in sealed outer ring 10, wherein：
The cross section of the sealed outer ring 10 be U-shaped, have in forked two pincers portions, described two pincers portions it is opposite
The caulking groove 11 being open on the outside of radially is formed between side, the inner surface of the caulking groove 11 is shiny surface；
The metal O-ring 20 is rolled by double-layer alloy steel band, is embedded at the caulking groove 11 of the sealed outer ring 10
It is interior；
And the characteristics of the utility model, is：The opposite side surfaces in two pincers portions of the sealed outer ring 10 are respectively along the gold
Belong to O-ring 20 it is circumferential at there are one or several (being two in the present embodiment) annular grooves 30.
So set, when utility model works, low temperature spring energy-storage sealing ring is squeezing space (i.e. frame shape in Fig. 2)
After middle extruding stress, two annular grooves 30 form three-layer sealed face 31 after squeezing stress, rely on multi-stage sealed effect, reduce valve
Influence of the microcosmic irregularity degree of body, valve seat sealing surface to valve seal performance, extends its sealing performance and service life, is also provided with
Preferably wiping ability.
And the metal O-ring that double-layer alloy steel band rolls has larger preload elastic potential energy and broader deformation abundant safely
Degree, enough elasticity effectively increases the sealing performance of sealing ring, can reduce valve body, valve seat because of machining accuracy error or due to
Under ultralow-temperature operation conditions part contraction distortion it is non-uniform and generate harmful effect, so that valve seat piston effect is normally established, really
Protecting valve seat and ball seal pair has enough seal pressures, for establishing for sealing reliability of the ball valve under ultralow-temperature operation conditions
Basis.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope defined by claim, can many modifications may be made, variation or it is equivalent, but
It falls within the scope of protection of the utility model.
Claims (3)
