Abstract
The utility model relates to a coupling type tooth thread sealing ring flange, which relates to contact type connecting and sealing pieces for circular and elliptic pipe flange interfaces made of metals and nonmetals of all specifications. The utility model solves the problem of easy leakage of a traditional plane contact form in already present flange plates. The utility model provides a coupling type tooth thread sealing ring flange which does not change an integral structure of the existing flange plate with national unified standard, and can also realize effective sealing, wherein, a connecting surface of one flange plate and a connecting surface of a corresponding flange plate are respectively provided with closed type annular tooth threads, the tooth threads adopt a coupling type contact, the tooth threads can adopt regular ripple shapes, trapezoid shapes, rectangular shapes, etc., wherein, an included angle formed by two sides of the tooth threads on the connecting surface of one flange plate is slightly smaller than an included angle formed by two sides of the tooth threads on the connecting surface of the corresponding flange plate. The number of the closed type annular tooth threads on the connecting surface of the flange plate is equal to or more than two.
Description
Technical field: the utility model relates to the circle of the metal of all specifications, nonmetal making, oval piping flange interface contact-type connects Sealing.
Background technique:
Be used for the pipeline of fluids such as conveying gas or liquid, " leak volume " at " leak volume ", especially pipe joint place is the most important technical order in the pipework.The flange-interface place is the significant points of reaction engineering quality, and therefore, flange is to connect in the pipework and the vitals that seals.Conveyance fluid, particularly carry the leakage problem of the piping flange joint of the fluid with certain pressure, be that conveyance conduit is failed the problem that effectively solves for a long time always.At present, the sealing of flange, the performance of-----" pad " except sealing medium (as rubber pad, asbestos packing, ox-hide pad) exists certain problem, the structure of flange plate self be being provided with of seal ring unreasonable also be the major reason of sewing.The flange plate surface of using in China's pipework all is the plane type water wave seal ring of unification of the motherland standard.After the engineering connection is fastening, do not change the plane type contact form of flange plate.Add aging, the be full of cracks of sealing medium, problem such as impure concentrates in together, and has just caused pipe joint often to leak.
Summary of the invention: the purpose of this utility model is to change the existing traditional plane type contact form of flange plate, and a kind of overall structure that neither changes existing unification of the motherland standard flange is provided, and can realize the couplinkg type tooth literary composition seal ring flange of effectively sealing.
Above-mentioned purpose is to realize like this, accompanying drawings is as follows: a kind of couplinkg type tooth line seal ring flange, the flange plate that flange plate 1 connects surface and correspondence is connected and is respectively equipped with closed annular tooth line 2 on the surface, this tooth line adopts the couplinkg type contact, the shape of tooth line can adopt corrugated, trapezoidal, the rectangle of rule, also can adopt irregular other shape, the flange plate that angle should be slightly less than with it matches that one of them flange plate connects two limits formations of surperficial upper tooth line is connected the angle that two limits of surperficial upper tooth line constitute.
The such scheme that the utility model provides because the employing of tooth line is the couplinkg type that canine tooth intersects, is indicated through experiment to have the following advantages: the area of contact that 1, has increased flange.Flange fastening after, the tooth line makes corresponding surface become the integral body that you are among us and we are among you, thereby has significantly improved the sealability of flange self, has effectively solved the technical problem that flange plate is sewed.
Description of drawings:
Fig. 1 is a couplinkg type tooth line seal ring flange arrangement schematic representation;
Fig. 2 is the worm's eye view of Fig. 1.
Among the figure: the 1st, flange plate 2 is closed annular tooth lines
Embodiment: the utility model is that the inspiration that is subjected to " screw thread " is finished when the sealing of research pipeline thread interface.With the water wave seal ring on the present flange, make tooth line seal ring into, make flange plate by original plane type contact, become the couplinkg type contact.And inside and outside circle diameter, the thickness of existing unification of the motherland standard flange, the diameter of fixed bolt hole, the equal no change in position.
Further specify content of the present utility model and embodiment below in conjunction with the accompanying drawing illustrated embodiment:
Consult Fig. 1 and Fig. 2: flange plate 1 selects the A3 material, diameter is 152mm, the caliber specification is selected 59mm, pipe range 150mm, flange plate is connected the surface become the closed annular tooth line 2 in 3 roads through machined into, the tooth line is shaped as isosceles trapezoid, and the angle that one of them flange connects two limits formations of surperficial upper tooth line is about 90 °, the angle that corresponding flange connects two limits formations of surperficial upper tooth line is 86 °, and the degree of depth of tooth line is 2.5mm.Then flange plate is welded in the two ends of long tube, guarantees the tooth line couplinkg type assembling contact on two corresponding flange plate.Be coated with efficient sealed dose of the flat pipeline thread interface of full coat (or loading onto rubber cushion) in the tooth line.By the pipework technical requirements connect fastening after, be placed on the enterprising line space gas of check-out console and suppress.When pressure rose to 2.0Mpa, pressurize did not still have and sews in 24 hours.Though above-mentioned test is only suppressed caliber 50mm, infer that from mechanical withstand voltage properties diameter can suitably increase tooth line number of rings, the degree of depth of perhaps deepening the tooth line greater than 50mm.The degree of depth that can suitably reduce the tooth line less than 50mm.
The utility model is useful for the couplinkg type tooth line seal ring on all metals, nonmetal, round, ellipse, NBS, the non-standard flange dish.
Claims (2)
1. couplinkg type tooth line seal ring flange, it is characterized in that flange plate that a flange plate (1) connects surface and correspondence is connected is respectively equipped with closed annular tooth line (2) on the surface, this tooth line adopts the couplinkg type contact, the shape of tooth line can adopt corrugated, trapezoidal, the rectangle of rule, and the flange plate that angle should be slightly less than with it matches that one of them flange plate connects two limits formations of surperficial upper tooth line is connected the angle that two limits of surperficial upper tooth line constitute.
2. couplinkg type tooth line seal ring flange according to claim 1 is characterized in that said flange plate (1) connects lip-deep closed annular tooth line (2) and answers 〉=2 rings.
