Abstract
The utility model is a packing set of the sealing material, utilizing in the filler of the fossil, the pharmacy, the food and the like industrial manufacture. The utility model comprises an out-shell 1 and a core set 2, wherein the core set 2 is in the middle of the out-shell 1, and the cross section is circular or foursquare. The utility model has excellent bounce impact force, overcoming the problem that the packing set of the original polyfluortetraethylene rend thread with poor bounce impact force affects the sealing property, and the utility model can be widely used to seal the pump and valve in the industrial manufacture.
Description
Technical field
The utility model relates to a kind of packing of industrial production field packing seal material.
Background technique
Be used for petrochemical industry at present, pharmacy, gold is controlled in papermaking, pipelines such as machinery, valve, pump, the packing that the flange connections of pressurized container is used as static seal, as flexible graphite stuffing, carbon fiber packing, teflon isolate a packing etc., all require certain withstand voltage, heatproof, sealing premium properties that spring-back force is good.But they are made with homogenous material, single structure shape, and as tablet, square or rectangular, each difference to some extent of their performance.Along with constantly improving of requiring of product processes and raising that the technological process sealability is required, the structure of the packing that various sealing member materials are made is constantly improved, in the hope of improving sealability.Meeting the needs of production of maximum possible.It is good that teflon isolates a packing turbidity test, can be widely used in medicine, the production industry of food, but its compression and back elastic force is desirable not enough, awaits further raising.
Summary of the invention
The utility model to polytetrafluoroethylene isolate a thread packing use in spring-back force also have dissatisfactory defective, structure at it designs correction, a kind of packing that includes the design technology project of outer and core root is provided, it is to be shaped on its sanction face for circular, the core root of square or rectangular in the centre that the polytetrafluoroethyl-ne of ordinary construction shape shape weighing apparatus isolates a packing.
This model utility is provided with the core root in the centre, it is rigid to reduce it in the use, it is good to have spring-back force, giving under the little situation of tight power, sealability is better than teflon and isolates a packing, and the original superperformance that keeps teflon to isolate a packing, be applicable to the demanding occasion of turbidity test, as the using scope of production fields such as chemical industry, medicine, food.
Description of drawings
Fig. 1 is the utility model topology view.
1-outer 2-core root
Embodiment
Details are as follows for the mode that technology contents of the present utility model is implemented with reference to the accompanying drawings.
As shown in Figure 1: outer 1 material of the present utility model is taken teflon and is isolated silk or the fragrant opinion of poly-propionitrile glass mixing, silicone rubber core root 2 is set in its centre, braiding moulded section is banded packing, outer 1 cross section of the present utility model is rectangular tablet, or square, there is punching bar silicone rubber core root 2 outer 1 centre, and this core root cross section is rounded or square.The utility model is used for the pump of industries such as chemical industry, pharmacy, food, and valve flange packing sealing under-195 ℃ of-25 ℃ of temperature, has high sealing performance in the working pressure 35Mpa scope.
Claims (1)
1, a kind of packing, it includes outer and the core root, and the centre that it is characterized in that skin (1) is shaped on its sanction and looks like circle, the core root (2) of square or rectangular.
