Abstract
A rectangular sealing ring relates to the technical field of sealing devices, in particular to the technical field of sealing devices of tank mouths of tank containers. The rectangular sealing ring comprises a rectangular rubber inner-core sealing ring, and a polytetrafluoroethylene coating layer with thickness ranging from 0.20mm to 0.50mm and manufactured via hot pressing is coated at an outer edge of the rectangular rubber sealing ring. The rectangular sealing ring realizes the purpose of zero joint, zero casting fins, long service lift, high cost performance, temperature resistance, corrosion resistance and aging resistance.
Description
Technical field
The utility model relates to the technical field of seal arrangement, relates in particular to the technical field that is fit to tank container Jar opening sealer device.
Background technique
The present jar of general square RunddichtringO of case, its tetrafluoro joint part is because of being destroyed when high temperature welds, adhesion when directly having influence on the product use, its product mold mold joint is in the inside and outside both sides of sealed picture in addition, therefore the mold joint overlap inevitably appears in the inner ring of product, not only influence product appearance, and the product inboard is the use working surface of seal ring just, the mold joint overlap occurs and illustrate that this place obviously is out of shape and produces the crack, in use easily torn and leakage of chemical liquid takes place by jar case inner high voltage.
Summary of the invention
The utility model purpose provides a kind of non-joint, non-trimming, long service life, cost performance height, heatproof and anticorrosion aging-resistant rectangular seal.
The utility model adopts following technological scheme:
A kind of rectangular seal is characterized in that comprising rubber rectangular ring, and the outer rim of rubber rectangular ring is enclosed with the teflon-coated layer that the thickness of making through hot pressing is 0.20～0.50mm.
The utility model adopts technique scheme, compared with prior art have following advantage: the utility model has overcome the deficiency that joint bag fluorine square RunddichtringO is arranged, the product non-joint, smooth smooth, there is not overlap, make product appearance perfect, because of the clad non-joint, the adhesion of teflon and rubber body obviously is better than traditional product, effectively promoted the total quality of product, prolonged the working life of product, improved cost performance of product, heatproof and anticorrosion ageing resistance are enhanced.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of rectangular seal is characterized in that comprising rubber rectangular ring 1, and the outer rim of rubber rectangular ring 1 is enclosed with the teflon-coated layer 2 that the thickness of making through hot pressing is 0.20～0.50mm.
It is to be cut into teflon turning sheet material rectangular according to size that joint polytetrafluoroethyltank tank case square RunddichtringO is arranged, the butt joint of the rectangular ring head of teflon is coated on outside the rubber raw material through high temperature welding lopping, again through the rubber vulcanizing machine press vulcanization moulding of heating, so must stay the vestige of joint on the product.Again because of the mold joint of its vulcanization of rubber mould is inside and outside both sides at product, so after the formed product, the mold joint overlap has inevitably also just appearred in its inside and outside both sides.
The utility model polytetrafluoroethyltank tank case square RunddichtringO is that direct stamping-out goes out complete circle on polytetrafluoroethylsheet sheet, and the rubber mould mold joint is the end face at product, so there is not joint in product behind the product sulfidization molding, its inboard smooth smooth overlap that also do not exist.
