Abstract
The utility model relates to a seal ring installed on mechanical seal equipment. The seal ring comprises a ring body, and a groove is arranged on the ring body along the middle axis of the ring body. The angle alpha formed by the center line of the section of the groove and the force bearing direction of the seal ring is from 30 DEG to 90 DEG. The seal ring has the advantage that the groove is arranged on the ring body of the seal ring to plug fluid media by using pressure of the fluid media. In addition, the seal ring is simple in structure, low in cost, and high in work reliability; and is suitable for high temperature, high voltage and strong corrosion fluid sealing.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to a kind of seal ring that is applicable to that high temperature, high pressure, deep-etching fluid-tight are used.
Background technique
At present, the seal ring that use in the mechanical seal field has O type rubber ring, the rubber-coated circle of FEP, polytetrafluoroethylene (PTFE) O type circle, polytetrafluoroethylene (PTFE) V-type circle etc., and its applicable situation is difference to some extent also.O shape rubber ring is only applicable to be lower than 180 ℃ occasion in temperature and uses.Import perfluorinated rubbers (KalreZ) is though O type rubber ring can be in the medium-term and long-term use of 327 ℃ of high temperature, but its price is the hundreds of times of General Purpose Rubber circle, rubber-coated circle of FEP and polytetrafluoroethylene (PTFE) seal ring decay resistance are stronger, but its matter is hard, rebound degree is low, yielding, unsteady weak effect.
The employed compensated loop seal ring of mechanical seal generally adopts rubber ring, but phenomenons such as in operating modes such as high pressure and deep-etching, extruding can appear in the General Purpose Rubber circle, swelling, influences the unsteady effect of compensated loop, obviously can't satisfy the usage requirement of mechanical seal long lifetime.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, cost is low, functional reliability is high, be applicable to high temperature, the seal ring of high pressure and deep-etching fluid-tight.
For achieving the above object, the technical solution adopted in the utility model is: a kind of seal ring, be installed on the mechanical seal device, described seal ring comprises circle body, described circle body upper edge wherein axial direction offers groove, and the center line in the cross section of described groove is 30 °-90 ° with the angle α that become by force direction of described seal ring.
Preferably, the cross section of described groove is a rectangle or trapezoidal.
Preferably, described groove comprises cell wall, bottom land, round-corner transition between described bottom land and the described cell wall.
Preferably, the degree of depth T of described groove is smaller or equal to the radius in the cross section of described circle body.
Seal ring of the present utility model in use, described groove need be positioned at the higher side of fluid medium pressure, utilizes the pressure shutoff flowing medium of flowing medium, realizes the sealing to high temperature, high pressure and deep-etching fluid.
Because technique scheme utilization, the utility model compared with prior art has following advantage: offer the pressure shutoff flowing medium that groove utilizes flowing medium because the utility model adopts on the circle body of seal ring, simple in structure, cost is low, functional reliability is high, is applicable to the sealing of high temperature, high pressure and deep-etching fluid.

Accompanying drawing 2 is an A of the present utility model portion zoomed-in view.
Accompanying drawing 3 is a B of the present utility model portion zoomed-in view.
Accompanying drawing 4 is a C of the present utility model portion zoomed-in view.
In the above accompanying drawing: 1, mechanical seal device; 2, circle body; 3, groove.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: referring to accompanying drawing 1 to shown in the accompanying drawing 5.
A kind of seal ring, be installed on the mechanical seal device 1, seal ring comprises circle body 2, circle body 2 upper edges wherein axial direction offer groove 3, the cross section of groove 3 is a rectangle or trapezoidal, groove 3 comprises cell wall, bottom land, round-corner transition between bottom land and the cell wall, and the degree of depth T of groove 3 is smaller or equal to the radius in the cross section of circle body 2.The center line in the cross section of groove 3 is 30 °-90 ° with the angle α that become by force direction of seal ring.
For example be installed on the seal ring of A, two positions of B, it is subjected to radial force, i.e. the power of the vertical direction in the accompanying drawing 1.Can see by accompanying drawing 2, be positioned at the A position seal ring circle body 2 upper edges wherein axial direction offer the groove 3 that the cross section is a rectangle, the center line in the cross section of groove 3 and the angle α that become by force direction of seal ring are that 45 ° and groove position 3 are in the higher side of fluid medium pressure.Can see by accompanying drawing 3, be positioned at the B position seal ring circle body 2 upper edges wherein axial direction to offer the cross section be trapezoidal groove 3, the center line in the cross section of groove 3 and the angle α that become by force direction of seal ring are that 90 ° and groove 3 are positioned at the higher side of fluid medium pressure.
Be installed on the seal ring of C position, it is subjected to axial force, i.e. the power of substantially horizontal in the accompanying drawing 1.Can see by accompanying drawing 4, be positioned at the C position seal ring circle body 2 upper edges wherein axial direction to offer the cross section be trapezoidal groove 3, the center line in the cross section of groove 3 and the angle α that become by force direction of seal ring are that 90 ° and groove 3 are positioned at the higher side of fluid medium pressure.
Above-mentioned seal ring adopts pure polytetrafluoroethylene (PTFE) or fills PTFE such as carbon graphite, glass fibre, titanium dioxide, to satisfy the sealing demand of medium under the different operating modes.
Because the application of technique scheme makes seal ring can utilize the pressure shutoff flowing medium of flowing medium, realizes the sealing to high temperature, high pressure and deep-etching fluid.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
