Description
Technical field
A kind of water pump extended life seal packing ring, for water-sealed pump, belong to seal washer technical field.
Background technology
Gasket seal or seal washer, as long as it is that a kind of place for having fluid for machinery, equipment, pipeline is exactly to use
Sealing spare part, using inside and outside, the material to seal.Gasket seal is with metal or nonmetallic tabular material, through cutting
To cut, the technique such as punching press or cutting is made, for the sealed connection between pipeline, the sealing between the parts and parts of machinery equipment
Connection.It can be divided into metallic packing and nonmetallic gasket seal by material.Metal has copper backing, stainless steel gasket, iron pad
Piece, aluminium backing etc..Nonmetallic has asbestos washer, non-asbestos pad, paper gasket, rubber sheet gasket etc..
Between seal washer is arranged on into two tie points, following weak point be present：
Due to constantly to tighten installed part during installation so that seal washer deforms between two installed parts, or even broken
Damage, installed part is because of reasons such as oxidations, it may appear that space, when seal washer deforms or damaged, installed part space occurs, will go out
The situation of existing leak.
The content of the invention
The purpose of this utility model is：Solves the deformation of existing seal washer or when space occurs in damaged, installed part, just
Occurring has the situation of leak, cause Sealing period and it is short the problem of；Provide a kind of water pump extended life seal packing ring.
The technical solution adopted in the utility model is as follows：
A kind of water pump extended life seal packing ring, including a round washer body, it is characterised in that：Round washer body
A cylindrical type packing ring is provided with inner ring edge, the inner and outer wall of cylindrical type packing ring is shape of threads.
Further, the outer ring that the round washer body includes the inner ring of inner circle side and is set in outside inner ring, inner ring ratio
Outer ring thickness 1-3mm, the inner ring are connected with outer ring.
Further, the upper surface or lower surface of the upper surface of the inner ring or lower surface and outer ring are in same level；Or
The upper and lower surface of outer ring is between the upper and lower surface of inner ring.
Further, the thickness of the cylindrical type packing ring is 0.5mm-1mm.
Further, the inner ring of the round washer body and outer ring include internal layer and the outer layer of wrapping inner layer, and internal layer is poly-
Urethane elastomeric material, outer layer are polytetrafluoroethyl coating films.
Further, the inner ring is connected with outer ring breakpoint.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
First, the utility model sets the one of a cylindrical type packing ring and two installed parts on the inner circle edge of round washer body
Inner and outer wall is engaged, and extends seal section, can be prevented that round washer body is damaged, be caused the situation of leak, and two
One cylindrical type packing ring is set between installed part, the inwall and an outer wall of seal section are not easy the corrosion of liquid body and space occur,
Installed part is effectively protected, also greatly extends Sealing period；
2nd, inner ring is thicker than outer ring in the utility model, and when may be such that two installed parts are tightened, outer ring just connects with two installed parts
Touch, tightening installed part will not make outer ring damaged and deform, can be further by outer ring when inner ring breakage has the situation of leak
Until the situation of preventing water leakage；
3rd, the thickness of cylindrical type packing ring is 0.5mm-1mm in the utility model, be in order to prevent cylindrical type packing ring blocked up,
Two installed parts can not be caused to install；
4th, round washer body is urethane rubber materials and polytetrafluoroethyl coating films in the utility model, is in order to anti-
Installed part is only tightened, makes packing ring deformation or damaged；
5th, inner ring is connected with outer ring breakpoint in the utility model, is to prevent inner ring to be badly deformed, does not have completely
During sealing function, it can only be sealed by the way that inner ring and cylindrical type packing ring are disassembled at breakpoint joint with outer ring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
