Abstract
The utility model relates to a combined sealing ring. The utility model is characterized in that the utility model comprises an engineering plastic base ring, one or two surfaces of which are respectively provided with a ring groove, wherein, one or double surfaces of the base ring are compounded with a non-asbestos fiber gland ring; one surface of the engineering plastic base ring can be also compounded with a metal material ring. The adoption of the structure makes the utility model has the characteristics of no leakage, attrition resistance, oil resistance, resistance to acidity and basicity and resistance to organic solvent; the utility model is suitable for pH value of zero to fourteen and temperature of-250 DEG C and 250 DEG C; the utility model is suitable for dynamic sealing devices, such as a split type piston, a ship screw shaft, a water turbine main shaft, etc., for corrosive high-temperature, cryogenic-and-cooling and high-pressure filling in which liquid phase and gaseous phase media of solid fine particles exist.
Description
Technical field
The utility model relates to seal element, and what be specifically related to is a kind of complex sealing ring that is combined by engineering plastics and packing.
Technical background
In the prior art, the machinery dynamic seal apparatus adopts the seal ring of leather, rubber, plastics usually, and operating modes such as medium that seals because of not exclusively being suitable for and temperature, pressure are leaked easily.For example: creep easily takes place in the leather not teflon in acid resistant alkali, rubber non-refractory, the plastics; When particularly having solid particle to exist in the sealing medium, the seal ring of described material often leaks because of Sealing is worn with regard to showing the not problem of abrasion performance, jeopardizes production, safety, causes economic loss and befouling environment.
The content of invention
Technical problem to be solved in the utility model is: a kind of complex sealing ring with characteristics such as zero leakage, abrasion performance, acid resistant alkali, organic solvent-resistants is provided.
For achieving the above object, the technical solution adopted in the utility model is such: promptly a kind of complex sealing ring is characterized in that: comprise the engineering plastics basic ring of one side or double-sided belt annular groove, wherein the one side of basic ring or the two-sided non-asbestos fiber packing ring that is compounded with; Or at a composite material ring of engineering plastics basic ring.
The utility model has the characteristics of zero leakage, abrasion performance, oil resistant, acid resistant alkali, organic solvent-resistant owing to described structure; Applicable media pH value 0～14, temperature-250 ℃～250 ℃; Be applicable to the liquid phase that there is solid particle, gas phase media, the device of moulding filler motive sealing of high temperature, deep cooling, the high pressure of corrosion is arranged.For example: on the equipment such as high pressure chemical industry plunger pump, reciprocating pump, the split type piston of heavy hydraulic cylinder, screw shaft of ship, hydraulic turbine main shaft.
Description of drawings
The utility model has following accompanying drawing:
Accompanying drawing 1 is the utility model basic ring embodiment's a structure sectional view;
Accompanying drawing 2 is the utility model combined sealing ring embodiment 1 a structure sectional view;
Accompanying drawing 3 is the utility model combined sealing ring embodiment 2 a structural representation;

In the accompanying drawing: 1-engineering plastics basic ring, 2-annular groove, 3-non-asbestos fiber packing ring, 4-metallic material ring.
Embodiment
Structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
Referring to accompanying drawing 1, the embodiment of (1) indefiniteness of engineering plastics basic ring among the figure shows: basic ring simultaneously has annular groove (2), and the cross section of annular groove is approximate trapezoidal.
Referring to accompanying drawing 2, in this embodiment, basic ring (1) two-sided has annular groove (2), and wherein the cross section of an annular groove is a concave arc shape, and the cross section of another annular groove is approximate trapezoidal; In being the annular groove of concave arc shape, cross section embedded the metallic material ring (4) that can match with the annular groove of concave arc shape.This embodiment is useful for the sealing of high temperature, high pressure.
Referring to accompanying drawing 3, in this embodiment, the one side of basic ring (1) has annular groove (2), and the bottom of non-asbestos fiber packing ring (3) is adhered in the annular groove, and the top exceeds notch.Between the two can bonding in forming die, typing.The motive sealing that this combined sealing ring is applicable to axle, cylinder body can realize the motive sealing zero leakage; Heavy wear, the axle of pulling or the dynamic seal apparatus of cylinder body are still had satisfied effect.The life-span of its zero leakage is more than 5-10 a times of leather, rubber, teflon seal ring.
Referring to accompanying drawing 4, in the present embodiment, in this embodiment, the one side of basic ring (1) has annular groove (2), and the bonding typing of non-asbestos fiber packing ring (3) is in basic ring (1) one side of trough of belt not.This combined sealing ring is applicable to end face seal, for example is used for the face seals of hydraulic turbine main shaft, the instead of rubber seal ring, and water leakage is little, and be more than 10 times of rubber seal ring working life.
Claims (5)
1, a kind of complex sealing ring is characterized in that: comprise the engineering plastics basic ring of one side or double-sided belt annular groove, wherein the one side of basic ring or the two-sided non-asbestos fiber packing ring that is compounded with; Or at a composite material ring of engineering plastics basic ring.
2, according to claims 1 described complex sealing ring, it is characterized in that: the one side of engineering plastics basic ring (1) has annular groove (2), and the cross section of annular groove is approximate trapezoidal.
3, according to claims 1 described complex sealing ring, it is characterized in that: engineering plastics basic ring (1) two-sided has annular groove (2), and wherein the cross section of an annular groove is a concave arc shape, and the cross section of another annular groove is approximate trapezoidal; In being the annular groove of concave arc shape, cross section embedded the metallic material ring (4) that can match with the annular groove of concave arc shape.
4, according to claims 1,2 described complex sealing rings, it is characterized in that: the one side of engineering plastics basic ring (1) has annular groove (2), and the bottom of non-asbestos fiber packing ring (3) is adhered in the annular groove, and the top exceeds notch.
5, according to claims 1,2 described complex sealing rings, it is characterized in that: the one side of engineering plastics basic ring (1) has annular groove (2), and the bonding typing of non-asbestos fiber packing ring (3) is in basic ring (1) one side of trough of belt not.
