Abstract
The utility model discloses a kind of tubing of resistance to Slow Crack, including ontology, ontology ecto-entad sets gradually jacket layer, flexible layer, fixing layer and bottom, several reinforcing ribs are provided between jacket layer and bottom, reinforcing rib includes pressure resistance column and the fixed plate for being set to pressure resistance column both ends, two fixed plates are respectively arranged in jacket layer and bottom, it is provided with several among flexible layer and reinforces pearl, compared with prior art, by the way that multilayer is arranged, and different materials is used, increases the performance of tubing, the Slow Crack for slowing down tubing extends the service life of tubing.
Description
Technical field
The utility model relates to pipe material fields, and in particular to a kind of tubing of resistance to Slow Crack.
Background technique
With the development of industry, greenhouse effects are increasingly severe, and the temperature in summer is very high, and the temperature in winter is very low, summer
The excessive phase to winter and winter to summer is very of short duration, and day and night temperature is very big, and the tubing of plastics, which passes through, to be exposed to the sun and freeze,
The amplitude expanded with heat and contract with cold is big, be easy to cause tubing Slow Crack, reduces the service life of tubing.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of good resistance to slow of compression and tensile strength
Fast crackle tubing.
In order to achieve the above objectives, the utility model adopts the following technical solutions:
A kind of resistance to Slow Crack tubing, including ontology, ontology ecto-entad set gradually jacket layer, flexible layer, fixing layer
And bottom, several reinforcing ribs are provided between jacket layer and bottom, reinforcing rib includes pressure resistance column and is set to pressure resistance column both ends
Fixed plate, two fixed plates are respectively arranged in jacket layer and bottom, several are provided among flexible layer and reinforces pearl.
Preferably, the height of aforementioned reinforcing rib is greater than the sum of flexible layer and the thickness of fixing layer, and reinforcing rib runs through flexible layer
And fixing layer, play the role of support.
More preferably, aforementioned jacket layer is made of thermoplastic polyester, and thermoplastic polyester belongs to engineering plastics, has good
Elasticity, it is easy to process, it can be very good protection tubing internal structure.
It is highly preferred that foregoing soft layer is made up of polypropylene, polypropylene chemical stability is fine, and anticorrosion ability is good,
The good ductility having can protect jacket layer in the case where expanding with heat and contract with cold, prevent jacket layer because of parectasis or
Slow crack caused by hypersystole.
It is further preferred that aforementioned fixing layer is made of polyvinyl chloride, stablizes and protect flexible layer.
Specifically, aforementioned bottom is made of polyphenylene oxide, has good physical property, can be good at playing as bottom
The structure of tubing is stablized in supporting role.
More preferably, the thickness of aforementioned jacket layer, flexible layer and fixing layer is respectively less than the thickness of bottom, the thickness of flexible layer
Equal to fixing layer, bottom and jacket layer play the role of fixed support, too thin not to be fixed easily.
It is highly preferred that being coated with heat-resisting antifreezing dope on the outside of aforementioned jacket layer, increases heat-resisting and freeze-proof, prevent tubing chronic
Crackle extends the service life of tubing.
Tubing is divided into multilayer by having the beneficial effect that for the utility model, using different materials, to overcome different materials
Contraction, have good physical property and stable chemical property, can preferably protect tubing, extend the use of tubing
It service life, can be by the intensity of strong tubing by reinforcing rib and reinforcement pearl.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
The meaning of appended drawing reference in figure: 1, jacket layer, 2, flexible layer, 3, fixing layer, 4, bottom, 5, reinforcing rib, 6, reinforcement

Specific embodiment
Specific introduce is made to the utility model below in conjunction with the drawings and specific embodiments.
A kind of resistance to Slow Crack tubing, including ontology, ontology ecto-entad set gradually jacket layer 1, flexible layer 2, fix
Layer 3 and bottom 4, are provided with several reinforcing ribs 5 between jacket layer 1 and bottom 4, reinforcing rib 5 includes pressure resistance column and is set to anti-
The fixed plate at compression leg both ends, two fixed plates are respectively arranged in jacket layer 1 and bottom 4, and the height of reinforcing rib 5 is greater than flexible layer 2
The sum of with the thickness of fixing layer 3, reinforcing rib 5 runs through flexible layer 2 and fixing layer 3, plays the role of support, sets among flexible layer 2
It is equipped with several and reinforces pearl 6.
Jacket layer 1 is made of thermoplastic polyester, and thermoplastic polyester belongs to engineering plastics, has good elasticity, convenient for adding
Work can be very good protection tubing internal structure, and flexible layer 2 is made up of polypropylene, and polypropylene chemical stability is fine, anticorrosion
It works well, the good ductility having can protect jacket layer 1 in the case where expanding with heat and contract with cold, and prevent jacket layer 1
Because of slow crack caused by parectasis or hypersystole, fixing layer 3 is made of polyvinyl chloride, stablizes and simultaneously protects flexible layer 2, bottom
Layer 4 is made of polyphenylene oxide, has good physical property, can be good at playing a supporting role as bottom 4, stablizes tubing
Structure.
The thickness of jacket layer 1, flexible layer 2 and fixing layer 3 is respectively less than the thickness of bottom 4, and the thickness of flexible layer 2, which is equal to, to be fixed
Layer 3, bottom 4 and jacket layer 1 play the role of fixed support, too thin not to be fixed easily, and are coated with heat-resisting antifreezing dope on the outside of jacket layer, increase
Add heat-resisting and freeze-proof, prevent tubing slow crack, extends the service life of tubing.
Tubing is divided into multilayer by having the beneficial effect that for the utility model, using different materials, to overcome different materials
Contraction, have good physical property and stable chemical property, can preferably protect tubing, extend the use of tubing
It service life, can be by the intensity of strong tubing by reinforcing rib and reinforcement pearl.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
Technical solution obtained, all falls in the protection scope of the utility model.
