Abstract
The utility model relates to the technical field of sealing packing, in particular to a combined wear-resisting packing ring. The combined wear-resisting packing ring comprises an annular packing ring body (1), a molybdenum disulfide coating coats the outer surface of the packing ring body (1), the packing ring body (1) comprises two base rings (11) and two back-to-back graphite sealing rings (12), the two base rings (11) are oppositely arranged, and the graphite sealing rings (12) are arranged between the two base rings (11). Compared with the prior art, the combined wear-resisting packing ring has the advantages that the sealing rings clamped between the symmetrical-arranged base rings are in tight connection with a sealing piece through the symmetrical-arranged base rings so that the self-lubrication and low-friction-coefficient characters of the graphite sealing rings can be expressed. In addition, the wear-resisting coating coats transition circular corners to improve the whole performance, therefore, the combined wear-resisting packing ring is suitable for the high-pressure large-line-number work environment, the mechanical using safety of equipment is effectively protected, and the service life of the equipment is effectively prolonged.
Description
Technical field
The utility model relates to the stuffing box packing technical field, particularly a kind of combination wear resistant filler ring.
Background technique
Carbon packing ring is a kind ofly to be applicable to oil, chemical industry and some have the environment of the strong corrosive medias such as soda acid, is installed on the mechanical seal product of various rotating equipments, reciprocating pump, valve etc.Common carbon packing ring is structure in the form of a ring, be Expanded graphite after shearing by mould be wound around the compacting form.Because the material behavior of graphite has the characteristics such as self lubricity is good, corrosion-resistant, produce and install relative conveniently, be one of environmental protection row stuffing box packing that current cost performance is higher.
Although the friction factor of graphite material is lower, at working condition requirements such as high strength, high line numbers, under high environment, work, or can produce wearing and tearing and then cause sealing to reduce and then cause leakage, often find that carbon packing ring damages in advance while changing packing ring, the corrosion phenomena that weight differs also occurs in the sealed member surface of its contact, cause the valve rod distortion of corroding, cause larger economic loss.
The model utility content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of rational in infrastructure, combination wear resistant filler ring of using safety, structural stability, wear resistant corrosion resistant is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of combination wear resistant filler ring described in the utility model, the packing ring body 1 that comprises ring-type, be coated with the molybdenum disulfide coating on the outer surface of body 1, described body 1 comprises two basic rings that are oppositely arranged 11, and is located at two graphite-seal rings 12 that arrange back-to-back between two basic rings 11.
Further, described basic ring 11 inner side ends are provided with annular projection, and seal ring 12 outside end faces are provided with the groove of the annular coordinated with basic ring 11.
Further, the seam crossing between described basic ring 11 outer rims and exterior edge face is provided with knuckle 2.
The utility model beneficial effect is: compared with prior art; the seal ring that the utility model makes to be located between it by symmetrically arranged basic ring forms tight the connection with Sealing; self lubricity and low coefficient of friction characteristic with the performance graphite seal; and knuckle and on knuckle wear-resistant coating to improve overall performance; make it to be applicable to the working environment of the high line number of High Voltage, effectively protect the machinery of equipment to use safety and life-span.
The accompanying drawing explanation
Fig. 1 is whole cross-sectional view of the present utility model.
In figure:
1, body; 2, knuckle; 11, basic ring; 12, seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of combination wear resistant filler ring described in the utility model, the packing ring body 1 that comprises ring-type, be coated with the molybdenum disulfide coating on the outer surface of body 1, described body 1 comprises two basic rings that are oppositely arranged 11, basic ring 11 adopts the aramid fibre compacting to form, and the seal ring 12 of being located at two between two basic rings 11 plumbago compactings that arrange back-to-back; Described basic ring 11 inner side ends are provided with annular projection, seal ring 12 outside end faces are provided with the groove of the annular coordinated with basic ring 11, basic ring 11 crush seal rings 12 and make seal ring 12 produce certain amount of deformation by annular projection, and then guarantee closely cooperating of seal ring 12 and black box, improved sealing effect, and fastening by it is carried out after packing ring is used a period of time, the working life that can effectively improve packing ring.
Seam crossing between described basic ring 11 outer rims and exterior edge face is provided with knuckle 2, and body 1 increases the tolerance intensity of exterior rim, the 5%-10% that the radius span of the knuckle on preferred body 1 is body 1 thickness when compacting by knuckle; Can avoid the corner inordinate wear of packing ring, improve the life-span of product, can also avoid body 1 to produce the situation that collapses quick-fried angle, limit, reduction in the numbers of seconds because colliding with.
The above is only better embodiment of the present utility model, and the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and is included in the utility model patent claim.
