Continuous, the long-time for demonstrate,proving equipment are carried out, and pipeline has to possess preferable anti-wear performance.
And traditional steel-structure tube either plastic pipe, in cereal transmits the course of work, continuous prolonged abrasion is held
It is worn out to be easily caused pipeline（Wherein steel-structure tube is usually 2 ~ 3 months, and plastic pipe is usually 1-2 months）, cause production line because of pipe
Road is abnormal and interrupts, and the pipeline worn out to these is changed also more troublesome in addition, is directly to weld steel in worn out position mostly
Plate or plastic plate carry out reinforcement repairing, and its damaged condition is still larger, it is necessary to often change, and interrupts continuous production, spills
Paddy or dust fall makes workshop hygiene difficult on the ground, and improves the production cost of enterprise, reduces production efficiency and life
Yield and quality.

Wear-resisting inner tube for wear resistant resin pipe, and the V of array setting is formed on the inner surface in the lower half section of this wear resistant resin pipe
Shape is raised, and the adjacent V-arrangement projection in these V-arrangement projections is two-by-two in groups, and set backwards with the raised opening direction of two V-arrangements of group
Put；Meanwhile one layer of cushion rubber layer is formed between wear-resisting inner tube and protection outer tube, on its interface with wear-resisting inner tube into
Type has one layer of cord fabric, and metal spiral skeleton is also formed in the cushion rubber layer.
In the utility model, the thickness of the wear-resisting inner tube is 3 ~ 5mm.
In the utility model, the raised setting of the V-arrangement is highly 3 ~ 5mm, and angle is 70 ~ 90 °, and both wings edge lengths are

In the utility model, the raised groove corner of the V-arrangement is set for arc-shaped transition.
In the utility model, the cushion rubber layer thickness is 5 ~ 8mm
In the utility model, the cord fabric is Kafra fiber weaving, and thickness is 0.8 ~ 1mm.
In the utility model, the protection outer tube is managed for CPVC, and its pipe thickness is 3 ~ 5mm.
Beneficial effect：Pipe structure of the present utility model can be replaced directly in production equipment to traditional delivery pipe
Change, improve the rub proofness of pipeline, extend the service life of pipeline, so as to reduce the production cost of enterprise.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to the preferred embodiment of Fig. 1, Fig. 2 a kind of high abrasion grain pipe, in the present embodiment, delivery pipe includes
Wear-resisting inner tube 2 and protection outer tube 6, wherein, protection outer tube 6 is that the CPVC that a layer thickness is 4mm is managed, the internal diameter of wear-resisting inner tube 2
For 500mm, the medial surface of protection inner tube 5 is molded over, is the wear resistant resin pipe that a layer thickness is 3mm, meanwhile, in wear-resisting inner tube 2
Medial surface on be provided with the V-arrangement projection 1 being arranged in array, the settings of these V-arrangement projections 1 is highly 4mm, angle be 80 ° and
Being set in groove corner for arc-shaped transition, both wings edge lengths are 50mm, are arranged in groups two-by-two, and with two V-arrangement projections 1 of group
Opening direction backwards to setting, and the spacing between adjacent V-arrangement projection 1 is 22mm.And in wear-resisting inner tube 2 and protection outer tube
It is 6mm cushion rubber layers 3 that a layer thickness is formed between 6, and it forms one layer of Kev and towed on interface with wear-resisting inner tube 2
The thickness for tieing up weaving is 1mm cord fabric 5, in addition, metal spiral skeleton 5 is also formed in cushion rubber layer 3, the gold
Category spiral skeleton 5 is alloy skeleton, has good intensity, and have splendid compatibility with the rubber in cushion rubber layer 3.
