Abstract
The utility model relates to a full teflon inverted dynamic seal, which belongs to the technical field of a sealing device. A seal lip is fused in a framework, 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 dynamic seal of a kind of full teflon i nternal lined type, 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 full teflon i nternal lined type dynamic seal 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.Seal lip 1 fusion is equipped with O shape circle 3 on the skeleton 2 in 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 by the polytetrafluoroethylmaterial material of filling, modification, and bulking agent adopts organic filler.Seal lip 1 pulls into horn shape, is carved with derotation thread groove 4 on the inwall and is enclosed within on the Ceramic shaft sleeve, and it can stop fluid to flow out along axial plane, and according to turning to of axle, the left-hand thread groove can be carved into left-handed or dextrorotation.Seal lip 1 fusion is in skeleton 2, and skeleton 2 adopts another kind of filled polytetrafluoroethylene material to form, and it plays the fixedly effect of lip.Rubber o-ring 3 is housed on skeleton 2, and O type circle 3 can play to keep and guarantee necessary axially elastic force after Sealing is clamped on the pump housing 1, and plays static sealing.
The utility model is the following advantage of tool compared with the prior art:
1, the various corrosive fluids of ability; 2, sealing is reliable, and can accomplish to leak is zero; 3, structure letter Single, easy to install; 4, low cost of manufacture, long service life; 5, its operating temperature is-200～+ 300 ℃, being sealed fluid pressure is 0.6～1.0MPa; 6, the purposes scope is wide, can be widely used in all kinds of chemical pumps, The movable sealing of food pump, Teat pipette and other type of pump and all kinds of strong corrosive fluids.
