Abstract
The utility model discloses a wear-resistant polyethylene elbow pipe, which belongs to pipeline fittings. The elbow pipe is a connecting piece used for particle material transmission pipelines; two ends of the elbow pipe are connected with pipelines with same calibers and different directions; the middle part of the elbow pipe is a bent pipe in smooth transition; the pipeline elbow pipe is positioned on a section surface of a center line; outlines on the inner and the outer pipe walls form concentric arcs; circle radius of the center line of the elbow pipe is 1.5 times larger than the caliber of the elbow pipe; and connecting flange plates are arranged at the two ends of the elbow pipe. Because the turning radius of the wear-resistant polyethylene elbow pipe is big, the transmission is smooth, and the resistance is small, the service life of the wear-resistant polyethylene elbow pipe is greatly prolonged, and the longest service life can last for more than 3 years, so that the production efficiency can be remarkably improved, and the running cost of equipment can be reduced.
Description
1, technical field: the utility model relates to a kind of channel bend, especially for the channel bend of granule materials conveying.
2, background technique: granule materials with line transportation than low, because polyethylene pipe and bigger 5～6 times and be applied in a large number than steel pipe with the composite pipe wear-resisting property of polythene material with vehicle transfer efficiency height, cost.But, the existing elbow that is used for the pipeline of particle transport, because of the straight line technology of loosing core is adopted in molding and forming, it is positioned at, and outside tube wall profile line is a circular arc on the cutting plane of center line, inboard tube wall profile line then is 90 or 135 and spends to the wire clamp angle.The elbow turning radius of this structure is little, resistance is big, quick abrasion, general about two months is worn out tube wall and scrapping.Not only consume material also influences production because frequent shutdown changes accessory.
3, summary of the invention: the purpose of this utility model is a kind of wear resistant polyethylene channel bend of design, this elbow be used for granule materials carry that its turning radius is big, resistance is little, not easy to wear, long service life has overcome the defective that existing elbow exists.Adopted following technological scheme for reaching this purpose: the wear resistant polyethylene channel bend is the link that is used for the granule materials conveyance conduit, and two ends are connected with pipeline with the bore different direction, and the centre is slick and sly excessive bend pipe.The about both sides tube wall profile line that channel bend is positioned on the cutting plane of center line is an isocentric circular arc, and elbow center line radius of arc is greater than 1.5 times of channel bend bores.There is mounting flange at the channel bend two ends.
The wear resistant polyethylene channel bend is big because of the turning radius, and the smooth resistance of conveying material is little, thereby improves working life greatly.Long life can surpass 3 years, thereby significantly improves manufacturing efficiency, reduces the equipment operation cost.
4, description of drawings: Fig. 1 is the structural representation of wear resistant polyethylene channel bend.
5, embodiment: be further described below in conjunction with accompanying drawing.
The wear resistant polyethylene channel bend is the link that is used for the granule materials conveyance conduit, and two ends are connected with pipeline with the bore different direction, and the centre is slick and sly excessive bend pipe.On the cutting plane that is positioned at the channel bend center line, inboard tube wall profile line (2) is an isocentric circular arc with outside tube wall profile line (1), and the radius of arc of channel bend center line can be greater than 1.5 times of channel bend bores.The pipeline knuckle radius is strengthened, improve the mass transport smoothness and reduce wearing and tearing.In order to simplify the conventional not installation of flanged (FLGD) channel bend, save the flange welding sequence, there is mounting flange (3) at the channel bend two ends.Simultaneously, in use reduced the tube wall slit that welded flange produces, avoided because of producing the disadvantage that defeated material eddy flow and local out-of-flatness make the wearing and tearing aggravation.
Claims (1)
1. wear resistant polyethylene channel bend, it is the link that is used for the granule materials conveyance conduit, two ends are connected-6 with pipeline with the bore different direction, the centre is slick and sly excessive bend pipe, it is characterized in that: the inboard tube wall profile line (2) that channel bend is positioned on the cutting plane of center line is isocentric circular arc with outside tube wall profile line (1), and channel bend center line radius of arc is greater than 1.5 times of channel bend bores; There is mounting flange (3) at the channel bend two ends.
