Abstract
The utility model relates to an expansion-compensation arrangement made of the polytetrafluorethylene, comprising a polytetrafluoroethylene corrugated tube and a flange disc, wherein, the shape of the polytetrafluoroethylene corrugated tube is a shrug narrow shape; the outer surface is coated with a metallic layer which is tightly attached with the outer surface; the ratio of the distance of the wave crest and the trough and the wave length is equal with or larger than 1. The expansion-compensation arrangement made of the polytetrafluorethylene overcomes the defect that the common expansion-compensation arrangement made of the polytetrafluorethylene does not bear the higher positive and negative pressure. The utility model is the ideal connection equipment of the pipeline for industries such as the chemical industry, the petroleum and the colorant.
Description
The utility model relates to a kind of tefloncompensator.
Tefloncompensator be industries such as present chemical industry, oil, dyestuff the pipe-line equipment that generally uses, it is to constitute behind polytetrafluoroethylbellows bellows two ends configuration flange plate.Though this tefloncompensator has good antiseptic property,, can not bear higher positive/negative pressure owing to be subjected to the restriction of itself material property, when malleation is too high, compensator is broken, easily interior again suction when negative pressure is too high, the normal production of influence need.
The purpose of this utility model is to provide a kind of tefloncompensator that can bear higher positive/negative pressure.
For realizing above-mentioned purpose, the outer surface of the utility model polytetrafluoroethylbellows bellows coats the metal layer that fits tightly with it, to strengthen its anti-malleation ability, correspondingly, for improving anti-negative pressure ability, the utility model becomes narrow shape to the Waveform Design of the polytetrafluoroethylbellows bellows of outer surface covered with metal layer.Like this, the rigidity of this polytetrafluoroethylbellows bellows tube wall just will be far longer than the polytetrafluoroethylbellows bellows of general energy prolate waveform, and its anti-negative pressure ability has also just increased.
Below, detailed content of the present utility model is described in conjunction with the accompanying drawings and embodiments.
Accompanying drawing is the utility model structural representation.
The utility model includes polytetrafluoroethylbellows bellows (1), and flange plate (2) coats the metal layer (3) that fits tightly with it at the outer surface of polytetrafluoroethylbellows bellows (1).As stainless steel, to strengthen its anti-malleation ability, simultaneously, the Waveform Design of the polytetrafluoroethylbellows bellows of covered with metal layer (3) is become narrow shape, and the ratio that makes distance and wavelength between crest, trough is more than or equal to 1.At this moment, thus the rigidity of polyfluortetraethylene pipe increases greatly can bear high negative.After the two ends of polytetrafluoroethylbellows bellows are equipped with flange plate (2), carry out flange and handle, form flange gasket (4), flange plate (2) is provided with the bolt hole (5) of the usefulness that is connected with pipeline.
The utility model has coated the metal layer that fits tightly with it at the outer surface of common tefloncompensator, the waveform of design has improved the rigidity of polytetrafluoroethylbellows bellows again, therefore the ability of anti-positive negative pressure strengthens greatly, having overcome the not high defective of common tefloncompensator withstand voltage properties, is chemical industry, oil, the desirable pipeline connection device of dye industry.
Claims (2)
1, a kind of tefloncompensator is made of polytetrafluoroethylbellows bellows and flange plate, and the waveform that it is characterized in that polytetrafluoroethylbellows bellows (1) is a narrow shape, and outer surface is coated with the metal layer (3) that fits tightly with it.
2, tefloncompensator according to claim 1 is characterized in that the crest of narrow shape polytetrafluoroethylbellows bellows, the distance between trough should be more than or equal to 1 with the ratio of wavelength.
