Grab 121, the grab 121 has the faceplate being fastened in the card slot, and the faceplate is abutted with the side wall of the card slot,
To prevent faceplate from skidding off from card slot.Further, the protrusion to card slot internal stretch can also be set at the notch of card slot
Portion.
The material of above-mentioned liner layer 20 can be high density polyethylene (HDPE), crosslinked polyethylene, nylon, polyamide, polyurethane or poly-
Vinylidene.Liner layer 20 can be squeezed by high density polyethylene (HDPE), crosslinked polyethylene, nylon, polyamide, polyurethane or Kynoar
It forms out, has the function of anticorrosion and antiseep, for keeping the integrality of internal conveying substance, not by outside contamination.
Above-mentioned resistance to compression armor 30 is mainly used to anti-internal pressure, that is, resists the conveying substance inside composite and flexible pipe 1
Radial pressure load can also resist part external pressure, can make composite and flexible pipe 1 in the use process of deep-sea, bear biggish
Pressure.It should be noted that resistance to compression armor 30 can be formed by connecting by stainless steel, titanium steel or carbon steel strip by button or lock,
As shown in Figures 4 to 6, it is preferred to use S type carbon steel steel band, c-type carbon steel steel band or T-type carbon steel steel band are by buckleing or locking connection
At.
Above by at least one layer of tension armor 41 of setting and abrasionproof between resistance to compression armor 30 and protection jacket layer 50
The combination layer 40 of layer 42 is mainly used for resisting in drawing force and part internal pressure, so that composite and flexible pipe 1 obtains torque,
Circumferential load and axial load are balanced, while can largely improve the resistance to corrosion of composite and flexible pipe 1 and resist tired
Labor ability.
In order to make to protect jacket layer 50 to have qualified intensity and sealing performance, the material of the protection jacket layer 50 is using polymerization
Object, it is specific enumerable for polyethylene, nano-polyethylene, polyvinyl chloride, polypropylene, polyurethane or polyamide etc., i.e. protection jacket layer
50 can be by extrusion moldings such as polyethylene, nano-polyethylene, polyvinyl chloride, polypropylene, polyurethane or polyamide.It is protected by setting
Jacket layer 50 can effectively prevent the chemical attack and biological corrosion of seawater, reduce the attachment of marine organisms, guarantee external fluid
Completely.
The material of the protection jacket layer 50 of the present embodiment preferably uses high density polyethylene (HDPE) (HDPE).High density polyethylene (HDPE) is one
Kind crystallinity height, nonpolar thermoplastic resin.High density polyethylene (HDPE) has good heat resistance, cold resistance and chemical stability,
The corrosion of acid and alkali resistance and various salts；Its dielectric properties, environmental stress crack resistance, wearability, electrical insulating property are preferable, also
Rigidity and toughness with higher, mechanical strength are good.
It should be noted that bonding between each layer of composite and flexible pipe 1 of the present embodiment by binder, pressure can also be passed through
