Description
Technical field
The utility model belongs to technical field of hydraulic mechanical equipment, and in particular to a kind of V-arrangement suitable for 60MPa super-pressure
Combination sealing arrangement.
Background technology
Hydraulic press is requisite pressing process equipment in industrial production, it is adaptable to moulding material it is compressing.With
Continuous increase of the user to pressing component demand, for hydraulic press, working cylinder effective diameter will be significantly increased, this
Just propose very special requirement to hydraulic machine working cylinder sealing structure.Because the cylinder body in hydraulic press is with the sealing of cylinder bottom
A kind of static seal, in plunger running, can produce higher pressure, and conventional hermetic circle can only bear 40MPa and following
Pressure, and conventional baffle ring is rectangle, pressurized rear particularly high pressure, the only power of axial direction, after sealing ring is pressurized vertically
Direction distortion is extruded in baffle ring and coupled face gap, easily causes sealing ring rupture, produces leakage.If producing hydraulic fluid leak,
Required operating pressure is not just reached, makes equipment to run well, cause hydraulic oil to be lost, environmental pollution.
Therefore, correct design and use sealing is the important guarantee that hydraulic test runs well.
Utility model content
The utility model aims to provide a kind of sealed reliable, and the V-arrangement suitable for 60MPa super-pressure of good leak-proof effect is combined
Sealing device.
Such technical scheme is adopted to solve above-mentioned technical problem the utility model：One kind is applied to 60MPa super-pressure
V-arrangement combination sealing arrangement, including right-angled trapezium groove, wedge baffle ring, v-ring and pressure ring, the one of the wedge baffle ring
Face is provided with the inclined-plane being engaged with the oblique waist of the right-angled trapezium of plunger, and another side is provided with the v-depression coordinated with v-ring,
Setting wedge baffle ring, v-ring and pressure ring are arranged in order from the oblique waist of right-angled trapezium groove to right angle waist direction.
Beneficial effect：The utility model simple structure, it is easy to installation and maintenance, to the eccentric load of cylinder body or cylinder bottom and partially
Heart motion has stronger adaptability, sealed reliable, good leak-proof effect, long service life.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Label in figure：1 ~ right-angled trapezium groove, 2 ~ wedge baffle ring, 3 ~ v-ring, 4 ~ pressure ring, 5 ~ support ring.
Specific embodiment
With reference to the accompanying drawings shown in 1 suitable for the V-arrangement combination sealing arrangement of 60MPa super-pressure, including right-angled trapezium groove 1, carve
Shape baffle ring 2, v-ring 3 and pressure ring 4, the one side of the wedge baffle ring 2 is provided with and is engaged with the oblique waist of the right-angled trapezium of plunger
Inclined-plane, another side be provided with v-ring 3 coordinate v-depression, the oblique waist from right-angled trapezium groove 1 is to right angle waist direction
It is arranged in order setting wedge baffle ring 2, v-ring 3 and pressure ring 4.
The width of described right-angled trapezium groove 1 is gradually little along depth direction.
Described v-ring 3 at least two, is provided with two-by-two one and matches somebody with somebody with v-ring 3 between v-ring 3
The support ring 5 of conjunction.
The side of described pressure ring 4 is provided with the V-arrangement point face coordinated with v-ring 3, and opposite side is designed to and right-angled trapezium
It is square that the right angle waist of groove 1 coordinates.
The cross section of described support ring 5 is V-arrangement.
The material of described v-ring 3 is canvas filler rubber.
The material of described wedge baffle ring 2 is QSn6-6-3 tin bronzes.
Described support ring 5 and the material of pressure ring 4 is phenolic resin.
Working method of the present utility model：When using, right-angled trapezium groove 1, next wedge are set in advance on plunger
Baffle ring 2 is put in right-angled trapezium groove 1, and makes the inclined-plane of wedge baffle ring 2 be close to the oblique waist of right-angled trapezium, v-ring
3rd, support ring 5 by being synchronously put in right-angled trapezium groove 1 after v-ring 3- support ring 5- shape sealing ring permutation and combination, and
Make in the v-depression of the embedded wedge baffle ring 2 in tip of v-ring 3, to place into pressure ring 4, make the embedded V in V-arrangement point face of pressure ring 4
V-ring 3 is compressed in shape sealing ring 3；When plunger motion produces pressure, the meeting stress of wedge baffle ring 2 compresses v-ring 3,
Make v-ring 3 plunger axle, radially have with coupled face good contact, pressure ring 4 pushes down v-ring 3 and prevents v-seal
Because displacement is squeezed, breakage causes hydraulic fluid leak to circle 3, and preferably protection sealing ring is injury-free.
The utility model fatigue resistance is big, sealed reliable, can effectively improve the service life of v-ring, reduces liquid
The damage thing rate that press is caused because of sealing problem.
