Description
Technical field
The utility model is related to sealing article more particularly to a kind of combined labyrinth and carbon gland gaskets.
Background technology
Gasket seal, which is a kind of is placed in the joint plane of pipeline, case or discrete, prevents medium osmosis
Seal, it is therefore an objective to the medium obstructed in pipeline or device leaks out.In the sealing system comprising gasket, medium is outward
The approach of leakage can be divided into boundary leakage and body leakage, and boundary leakage is by existing gap between gasket surface and flange face
Toward external leakage, body leakage is then that medium is leaked outward by hole existing for gasket internal structure.
In the prior art, it is farthest to reduce main body leakage, almost all of gasket seal product is monoblock type
Structure, therefore required making mold is also larger, especially to the gasket seal of some large-sizes, mold also correspondingly needs
Increase, not only Mold Making is costly, and due to being limited by cavity quantity, and production efficiency is also relatively low.Therefore, it is necessary to
A kind of combined labyrinth and carbon gland gasket is developed, in this way, multiple die cavitys can be arranged in a mold, is substantially reduced the size of mold, is reduced
Die cost improves the production efficiency of gasket seal.
Utility model content
The utility model is based on described in above-mentioned background technology, it is therefore an objective to a kind of combined labyrinth and carbon gland gasket is developed, if so, originally
The structure of one monoblock type die cavity of arrangement is only capable of in a mold, now, under the premise of not increasing die structure size, just
It can arrange multiple segmented die cavitys, greatly improve the production efficiency of gasket seal, while also reduce the manufacturing cost of mold.
The utility model is realized by the following technical solutions：
A kind of combined labyrinth and carbon gland gasket includes the pluggable circular body together of two structures unanimously, and the circle is originally
The center of body offers through-hole, it is characterised in that：It is provided with corresponding inserting column and bellmouth on the forward surface of two circular body,
The ring packing line concentric with the through-hole is provided on the side surface up and down of the circular body, the ring packing line is opposite
The hollow compression groove consistent with the ring packing line tracking is equipped in the circular body answered；The outer waist side of the circular body
Equipped with telescopic chute, the surface of the telescopic chute is coated with anticorrosion layer.
Further, the quantity of the ring packing line is at least two.
Further, the shape of the hollow compression groove is round either rectangle, quantity and the annular of hollow compression groove
Seal line quantity is consistent.
Further, the shape of the telescopic chute is trapezoidal.
Further, side surface is equipped with the sealing no more than ring packing line half height to the circular body up and down
Coating.The seal coating is nitrile rubber or silica gel.
Further, the inner surface of the through-hole is coated with self-lubricating layer, and the self-lubricating layer is polyimides, polyethers ether
One kind of ketone, polytetrafluoroethylene (PTFE).
Compared with prior art, the utility model has the beneficial effects that：
1, integral seal gasket in the prior art is used into sectionally assembled design, in this way, originally in a mold
In be only capable of the mould structure of one monoblock type die cavity of arrangement and can not increase mold knot now using after sectional design
Under the premise of structure size, so that it may arrange multiple segmented die cavitys, greatly improve the utilization rate of mold, reduce the production costs of mold
With greatly improving the production efficiency of gasket seal.
2, the utility model increases self-lubricating layer in the inner edge of ring body, is assembled convenient for the gasket seal；In annular
The side surface up and down of ontology is additionally arranged seal coating, seal line, can increase leakproofness；By in intrinsic hollow compression groove
And the telescopic chute of ontology waist side so that this gasket seal can get larger flexible deformation, reach a preferable seal pressure,
Auxiliary increases the leakproofness of the product again, thus greatly reduces slip.
Description of the drawings
Fig. 1 is utility model structural schematic diagram；
Fig. 2 is the sectional view of Fig. 1.
Specific implementation mode
The embodiments of the present invention are described in detail below, it can be by claim but the utility model is novel
It limits and the multitude of different ways of covering is implemented.
A kind of combined labyrinth and carbon gland gasket includes the pluggable circular body 1 together of two structures unanimously, and the circle is originally
The center of body 1 offers through-hole 2, and corresponding inserting column 7 and bellmouth 8, inserting column 7 are provided on the forward surface of any one circular body 1
After 8 grafting of bellmouth, two circular bodies 1 are combined into a complete gasket seal；After grafting again through aqueous colloidal without
Machine binder bonds.
The center of the circular body 1 offers through-hole 2, and the inner surface of the through-hole 2 is coated with self-lubricating layer 20, described
Self-lubricating layer 20 is one kind of polyimides, polyether-ether-ketone, polytetrafluoroethylene (PTFE)；It is set on the side surface up and down of the circular body 1
It is equipped with the ring packing line 3 concentric with the through-hole 2, the quantity of the ring packing line 3 is at least two；The ring packing
It is equipped with the hollow compression groove 6 consistent with 3 track of ring packing line in 3 corresponding circular body 1 of line；The circular body
1 outer waist side is equipped with telescopic chute 5, and the surface of the telescopic chute 5 is coated with anticorrosion layer 50.
