Abstract
The invention discloses a polytetrafluoroethylene corrugated pipe. The polytetrafluoroethylene corrugated pipe comprises an upper end flange, a lower end flange and a pipe body; the pipe body is arranged between the upper end flange and the lower end flange; the pipe body comprises an anti-sticking layer, an inner polytetrafluoroethylene layer, a glass fiber layer, an outer polytetrafluoroethylene layer and a rubber layer in the order from inside to outside; the anti-sticking layer is glued with the inner polytetrafluoroethylene layer by virtue of hot pressing; the glass fiber layer is fused between the inner polytetrafluoroethylene layer and the outer polytetrafluoroethylene layer; the rubber layer is connected with the outer polytetrafluoroethylene layer by use of a thermoplastic adhesive layer; a compression spring is arranged at the corrugated part of the pipe body. In this way, the polytetrafluoroethylene corrugated pipe is good in corrosion resistance and high in strength; the lines are not glued to each other due to the influence of the use environment and then cannot be broken; meanwhile, during drawing operation, the external force can be reduced and the corresponding power energy source can be saved.
Description
Technical field
The present invention relates to plastic article, particularly relate to a kind of polytetrafluoroethylbellows bellows.
Background technique
The mechanical property religion of teflon is soft, has again good corrosion resistance, high-lubricity and high wear resistance simultaneously, therefore conventional the and various pipeline of production.
Bellows is one of goods of teflon, polytetrafluoroethylbellows bellows of the prior art all can meet Production requirement in structure and intensity, but in use long or temperature is too high time, cause bellows ripple and easily occur bonding between ripple, cause bellows interior to break; Mutually extrude between ripple and ripple simultaneously, undulations surrounding is worn and torn and breaks, reduce the working life of bellows.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of polytetrafluoroethylbellows bellows of kind of the present invention, there is good corrosion resistance, intensity is high, the impact of Environmental Conditions can not be subject between ripple with ripple and produce bonding, ripple is caused to break, when operating when stretching simultaneously, can external force be reduced, save corresponding power source.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of polytetrafluoroethylbellows bellows, comprise and connect end flange, lower end flange and body, described body is arranged between upper flanges and lower end flange, institute's body comprises the adherent layer set gradually from inside to outside, interior polytetrafluoroethylene floor, glass fibre layer, outer polytetrafluoroethylene floor and rubber layer, described adherent layer and interior polytetrafluoroethylene floor form by being hot bonding, affiliated glass fibre layer clinkering is between interior polytetrafluoroethylene floor and outer polytetrafluoroethylene floor, described rubber layer is connected with outer polytetrafluoroethylene floor by thermoplastic adhesive's layer, described body ripple place is provided with Compress Spring.
In the present invention's preferred embodiments, described Compress Spring and body axis being parallel are arranged.
In the present invention's preferred embodiments, the thickness of described interior polytetrafluoroethylene floor is 3mm, and the thickness of described outer polytetrafluoroethylene floor is 4mm.
In the present invention's preferred embodiments, described body thickness is 15mm.
The invention has the beneficial effects as follows: a kind of polytetrafluoroethylbellows bellows of the present invention, there is good corrosion resistance, intensity is high, the impact of Environmental Conditions can not be subject between ripple with ripple and produce bonding, ripple is caused to break, when operating when stretching simultaneously, can external force be reduced, save corresponding power source.
