Abstract
In order to solve the nonmetal sealing gasket bearing capacity deficiency on market, metallic gasket is easy to wear, working life is short, and affected by various factors, pipeline angle in application there will be deviation, the problem that installation precision is low, a kind of new type rubber gasket structure is proposed, comprise metal frame and rubber, it is characterized in that: rubber is evenly coated on metal frame outside, metal frame is comprised of with two journal stirrups that are arranged on its outer ring the lock washer body of ring, on two journal stirrups, be all provided with long positioning hole, lock washer body toroidal surface is provided with the rubber seal waterline of annular protrusion, this structure is by adopting metal frame and the vulcanization of rubber to be integral, metal frame provides rigid support pipeline pressure, rubber plays sealing and wear-resisting effect, bearing capacity is strong, wear-resistant, the life-span is long, the journal stirrup of this structure is provided with the positioning hole of certain angle, effectively play the effect that regulates sealing and compensation pipeline setting angle deviation, improved positioning precision, simple in structure, easy to use.
Description
Technical field
The utility model relates to pipeline auxiliary device technical field, especially a kind of new type rubber gasket structure.
Background technique
Pipeline is the visual plant in ore pulp and the transportation of other liquid and other medium, in practice, due to the impact of the factors such as pipeline processing precision and on-the-spot installation environment, pipeline there will be deviation when turning round in angle, this just need to proofread and correct angle with pad, to meet pipeline installation requirements.
Pad is two mechanical seals between object, conventionally preventing from being stressed between two objects, the leakage of naturally expanding with heat and contract with cold of corrosion and pipeline, at present, in the pipe joint joint of pipeline, conventionally can use pad, for sealing various media; Sealing gasket on market mainly contains metallic gasket and nonmetal sealing gasket, and in actual use, in pipeline, because metallic gasket is installed, produces gap one, easily causes fluid turbulence, and its metal part is not wear-resistant.Bearing capacity at nonmetal sealing gasket is limited, generally only uses during low pressure.
Summary of the invention
In order to solve, nonmetal sealing gasket bearing capacity on market is not enough, metallic gasket is easy to wear, working life is short, and affected by various factors, pipeline angle in application there will be deviation, problem that installation precision is low, a kind of new type rubber gasket structure is proposed, this structure not only good sealing effect, wear-resistant, the life-span is long, and simple in structure, easy to use, positioning precision is high.
A kind of new type rubber gasket structure, comprise metal frame and rubber, it is characterized in that: rubber is evenly coated on metal frame outside, metal frame is comprised of with two journal stirrups that are arranged on its outer ring the lock washer body of ring, on two journal stirrups, be all provided with long positioning hole, lock washer body toroidal surface is provided with the rubber seal waterline of annular protrusion.
Described positioning hole also can be set to plural circular hole.
Described rubber gasket can be also plain seal pad.
Beneficial effect: this structure is by adopting metal frame and the vulcanization of rubber to be integral, metal frame provides rigid support pipeline pressure, rubber plays sealing and wear-resisting effect, bearing capacity is high, wear-resistant, the life-span is long, the journal stirrup of this structure is provided with the positioning hole of certain angle, effectively play the effect that regulates sealing and compensation pipeline setting angle deviation, improved positioning precision, simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model lock washer journal stirrup is provided with long positioning hole.
Fig. 2 is the structural representation that the utility model lock washer journal stirrup is provided with two round positioning holes.
Fig. 3 is the structural representation of the utility model plain seal pad.
In figure: 1-rubber; 2-seals waterline; 3-metal frame; 4-lock washer body; 5-positioning hole; 6-journal stirrup; 7-flat gasket body.
Embodiment
As shown in Figure 1, 2, a kind of new type rubber gasket structure, comprise metal frame 3 and rubber 1, rubber 1 is evenly coated on metal frame 3 outsides, metal frame 3 is comprised of with two journal stirrups 6 that are arranged on its outer ring the lock washer body 4 of ring, on two journal stirrups 6, be all provided with long positioning hole 5, the rubber seal waterline 2 of annular protrusion is set on lock washer body 4 toroidal surfaces.
Described positioning hole 5 also can be set to two circular holes.
As shown in Figure 3, a kind of new type rubber gasket structure, comprise metal frame 3 and rubber 1, rubber 1 is evenly coated on metal frame 3 outsides, metal frame 3 is comprised of with two journal stirrups 6 that are arranged on its outer ring the flat gasket body 7 of ring, on two journal stirrups 6, be all provided with circular positioning hole 5, flat gasket body 7 toroidal surfaces are provided with the sealing waterline 2 of annular protrusion.
With DN125, PN6.3MPa pipeline is example, this specification respective flange has 8 uniform mounting holes altogether, the angle in adjacent two holes is 45 °, in the utility model, the positioning hole of sealing inclined pad is made as to long hole shape, angle ɑ=22.5 °, during installation, sealing inclined pad is arranged in the roughly direction that needs to regulate, then rotating gasket is finely tuned; In practice, can adjust as required the size of angle ɑ, as 15 °, 20 ° etc., also can establish two round positioning holes with identical angle and realize accurate adjustment angle direction, and can realize the angular adjustment of any direction.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
