Abstract
The utility model relates to a full teflon everting dynamic seal, which belongs to the technical field of a sealing device. A framework is fused on an outer end surface of a seal lip, and an O-shaped ring is arranged on the framework. The seal lip is pulled into a horn shape, and is carved with a derotation thread groove. The utility model has the advantages of various corrosive fluids resistance, reliable seal, zero leakage, simple structure, convenient installation and operation, low manufacture cost, long service life, and wide purpose. The utility model can be widely used for dynamically sealing various chemical pumps, food pumps, drug pumps, other type pumps, and various strong corrosive fluids.
Description
The utility model relates to the type dynamic seal of turning up of a kind of full teflon, is used for all kinds of pumps, seals, and belongs to the seal arrangement technical field.
Before the utility model is made, in prior art, be used for all kinds of chemical pumps, food pump, the motive sealing of Teat pipette and other all kinds of pumps and all kinds of severe corrosive fluids.It mainly adopts the lip seal or the mechanical seal of fluorine rubber.The Sealing manufacture cost height of this kind structure, expensive, the easy leakage of price, installation, use inconvenience, working life is short.
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple in structure, easy to install and use, and sealability is reliable, the type dynamic seal of turning up of the full teflon of the various corrosive fluids of ability.
Main solution of the present utility model is achieved in that it mainly encloses 3 by seal lip 1, skeleton 2, O shape and forms.Skeleton 2 fusions are on seal lip 1 exterior edge face, and O shape circle 3 is installed on the skeleton 2.
Description of drawings:
Fig. 1 is the utility model structural front view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model seal lip 1 is made up of the polytetrafluoroethylmaterial material of filling, modification, and bulking agent adopts organic filler.Seal lip 1 pulls into horn shape, and its inwall is carved with derotation thread groove 4 and is enclosed within on the ceramic jacket, can stop a last fluid to ooze out.According to the sense of rotation of axle, the derotation thread groove can be carved into left-handed or dextrorotation.Skeleton 2 adopts another kind of filled polytetrafluoroethylene material to form.Skeleton 2 fusions are on seal lip 1 exterior edge face, and it plays fixedly lip effect.Rubber o-ring 3 is installed on the skeleton 2, and it can keep the axial pressing force of Sealing, and is not loosening after guaranteeing to be pressed on the pump housing.
Compared with the prior art the utility model has the following advantages:
1, the various corrosive fluids of ability; 2, sealing is reliable, and can accomplish to leak is zero; 3, its work Temperature is-200～+ 300 ℃, and being sealed fluid pressure is 0.6～1.0MPa; 4, simple in structure, installation makes With convenient; 5, low cost of manufacture, long service life; 6, the purposes scope is wide, can be widely used in all kinds ofization The movable sealing of worker's pump, food pump, Teat pipette and other type of pump and all kinds of strong corrosive fluids.
