Abstract
The invention discloses a sealing element made of composite materials. The sealing element made of the composite materials comprises a metal wire, argil, flexible graphite and binding agents which enable the metal wire, the argil and the flexible graphite to be bound together. The sealing element made of the composite materials has the characteristics of high strength, good high temperature and low temperature resistance and corrosion resistance, and widens the application range of ball valves. Particularly, the sealing element can meet the requirement of a refrigerating system in a high-temperature and high-pressure environment.
Description
Technical field
The invention belongs to technical field of sealing technology, be specifically related to a kind of composite material sealing part.
Background technique
At present, in field of sealing technology, widely use General Purpose Rubber as sealing material, but because resistance to temperature range is less, and easily produce deterioration phenomenon, working life is short, therefore, cannot meet the usage requirement of high temperature and high pressure environment, as CO
2the usage requirement of such Novel cooling medium refrigeration system applied environment.
Summary of the invention
In order to solve the problem, the invention provides a kind of composite material sealing part, advanced composite material (ACM) Sealing of the present invention, have that intensity is high, resistant of high or low temperature good, corrosion resistant characteristic, make the applied widely of ball valve, especially outstanding, the requirement of the refrigeration system of high temperature and high pressure environment can be met.
The binder that composite material sealing part of the present invention comprises wire, potter's clay, Expanded graphite and described wire, described potter's clay, described Expanded graphite is bonded together.
Composite material sealing part as above, described composite material sealing part is made up of wire, potter's clay, Expanded graphite and binder, and, the mass percent of described potter's clay is greater than described mass percent wiry, and described mass percent wiry is greater than the mass percent of described graphite.
Composite material sealing part as above, in described composite material sealing part, described mass percent wiry is 20% ~ 40%, the mass percent of described potter's clay is 45% ~ 65%, the mass percent of described graphite is 5% ~ 15%, and the mass percent of described binder is 1% ~ 5%.
Composite material sealing part as above, described binder is specially polyethyleneglycol.
Composite material sealing part as above, described wire is specially Stainless Steel Wire or nickel wire.
Composite material sealing part as above, the structure of described composite material sealing part is the cylindrical body of ring.
Composite material sealing part as above, described composite material sealing part is the open circles circular cylinder that circumference has opening portion.
Composite material sealing part of the present invention, owing to have employed novel compound proportioning, therefore there is intensity high, the characteristic of resistant of high or low temperature good (namely can be applicable to larger high/low temperature temperature range), good corrosion resistance, therefore, it is applied widely, such as, with field of refrigeration, it goes for multiple coolant refrigeration system, especially can meet the refrigeration system usage requirement of high temperature and high pressure environment.
Accompanying drawing explanation
Figure 1 shows that the stereogram of the specific embodiment one of composite material sealing part of the present invention;
Figure 2 shows that the stereogram of the specific embodiment two of composite material sealing part of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
Composite material sealing part of the present invention comprises wire, potter's clay, Expanded graphite and the binder by aforementioned metal silk, potter's clay, Expanded graphite good bond.Composite material sealing part adopts the reason of aforesaid wire, potter's clay, Expanded graphite and binder to be, wire can ensure the intensity of composite material sealing part.Potter's clay has the feature of fabulous plasticity, corrosion resistance, wear resistance, high temperature resistant low property.Expanded graphite has the little feature of resistant of high or low temperature, corrosion resistance, tightness and friction factor, has good lubricity.In this specific embodiment, aforesaid binder can be polyethyleneglycol.The effect of binder is make wire, potter's clay and Expanded graphite good bond on the one hand, and binder itself also has lubrication on the other hand.
As a kind of embodiment, in the present embodiment, composite material sealing part is made up of wire, potter's clay, Expanded graphite and binder.Further, the mass percent of potter's clay is greater than mass percent wiry, and mass percent wiry is greater than the mass percent of described graphite.Specifically, can be mass percent wiry be 20% ~ 40%, the mass percent of potter's clay be 45% ~ 65%, and the mass percent of described graphite is 5% ~ 15%, and the mass percent of described binder is 1% ~ 5%.Composite material sealing part adopts aforesaid composition proportion relation to be because if mass percent wiry is lower than 20%, can cause the strength deficiency of composite material sealing part 7, if higher than 40%, increase cost of production; If the mass percent of potter's clay is lower than 45%, increase cost of production on the one hand, affect plasticity and the resistant of high or low temperature of composite material sealing part on the other hand, if higher than 65%, affect the intensity of composite material sealing part.The proportion relation of foregoing soft graphite and binder, while the intensity ensureing composite material sealing part and resistant of high or low temperature, reduces the friction factor of composite material sealing part.In order to improve the intensity of composite material sealing part, aforesaid wire adopts Stainless Steel Wire or nickel wire.
Because its component determines it, composite material sealing part of the present invention, has that resistance to intensity region is wide, resistant of high or low temperature is good, the advantage of high pressure resistant, long service life.The working life of composite material sealing part is more than hundred times of common graphite filler and common plastics filler, and can be applicable to the high/low temperature temperature range of-40 DEG C ~+180 DEG C, and it even can meet the requirement of larger temperature range.Therefore, composite material sealing part applied range of the present invention, to be applied in refrigeration system, it can be applicable to, in most refrigeration systems, such as, go for requiring that high High Temperature High Pressure refrigeration system is (as CO to sealability
2in coolant system).
Figure 1 shows that the stereogram of the specific embodiment one of composite material sealing part of the present invention.
As shown in Figure 1, in the present embodiment, the structure of composite material sealing part is the cylindrical body of complete ring.When applying it as Sealing, only can use one, also can two or morely multiplely to use simultaneously.
Figure 2 shows that the stereogram of the specific embodiment two of composite material sealing part of the present invention.
As shown in Figure 2, in the present embodiment, the structure of composite material sealing part is the open circles circular cylinder that circumference has opening portion.Circumference carries out the design of opening portion, is the distortion adaptability in order to increase composite material sealing part, and can reduces the required precision adding internal footpath size in man-hour, and is convenient to assembling.
Composite material sealing part of the present invention, it has, and intensity is high, resistant of high or low temperature good (can be applicable to the high/low temperature temperature range of-40 DEG C ~+180 DEG C, it even can meet the requirement of larger temperature range), good corrosion resistance, therefore, it is applied widely, and to be applied to field of refrigeration, it can as the Sealing of valve in the refrigeration system of high temperature and high pressure environment.
The above is only a kind of embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
