Abstract
The utility model relates to a wearproof bend head for wind powder pipes, which belongs to the technical field of pipelines and pipe pieces. According to the momentum theorem, the utility model adopts an isolating and flow guiding technique, namely adding an isolating and flow guiding plate in a bend head of a wind powder pipe to reduce function accumulation of impact caused by the centrifugal force of powder granules on the external bend of the bend head for a wind powder pipe, reduce the abrasion of the impact of powder granules, and can change the concentration abrasion position on the external bend of the bend head at the same time. The isolating and flow guiding plate is arranged between the upper wall and the lower wall of the inner part of the utility model, and the bend angle of the isolating and flow guiding plate is consistent with the bend angle of the utility model. With simple structure, the utility model can reduce abrasion in the utility model ideally and extends the service life of the utility model. The utility model has the advantages of easy production, practice and application.
Description
The utility model belongs to the pipe fitting technical field, mainly proposes a kind of wind powder pipe Wear-proof bend.
The wear phenomenon that relates to its elbow existence of pipeline of carrying some material powder is comparatively serious, comparatively thorny and be not resolved as the wearing and tearing of wind powder pipe elbow always, what propose manufactures with composite materials such as abrasion-resistant cast steel material, rubber, excurvation coating iron sheet at elbow waters measures such as cast stone, received certain effect, but it is also more serious to wear and tear, and the steel breakage is bigger.
The purpose of this utility model promptly produces thus, proposes a kind of wind powder pipe Wear-proof bend, makes it can solve the wear problem that existing elbow exists, and prolongs the working life of elbow, reduces the steel loss.
The utility model is finished the technological scheme that the invention task takes; According to theorem of momentum, adopt and isolate diversion technology, promptly in the wind powder pipe elbow, install the isolation guide plate additional; The wearing and tearing of wind powder pipe elbow mainly are the caused bump abrasive wears of accumulation by wind powder bump momentum in the wind powder pipe elbow excurvation, alternating stress is bigger, install the isolation guide plate in the elbow additional, can reduce on the wind powder pipe elbow excurvation powder centrifugal force and cause the accumulation of bump kinetic energy, reduce powder bump abrasive wear; Also can change concentrated abration position on the elbow excurvation after installing the isolation guide plate simultaneously in the wind powder pipe elbow additional, make the relative uniform wear of excurvation, also can improve the excurvation wear-out life; Isolate guide plate and be arranged in the elbow, up and down between the tube wall, its bend angle is consistent with angle of bend in elbow.
Can consider to isolate the position that guide plate is arranged at close excurvation in the elbow.
Can consider to isolate the guide plate wooden partition and the excurvation inwall is designed to zigzag structure.
The Wear-proof bend structural design that the utility model proposes is comparatively simple, but the existing wearing and tearing of minimizing elbow that can be comparatively desirable, prolongs the working life of elbow, is easy to manufacturing simultaneously and practices.
The accompanying drawing that the utility model embodiment provides is;
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the sectional drawing of Fig. 1.
Further be illustrated in conjunction with the accompanying drawings: as shown in drawings, the Wear-proof bend that the utility model proposes, mainly be on former elbow structure, in elbow, to install to isolate guide plate 2, its be connected in the elbow up and down between the tube wall (pourable or alternate manner moulding) become one structure with it, its bend angle is consistent with angle of bend, be arranged at the position of near partially excurvation 1 in elbow, the wooden partition and the bend pipe 1 excurvation inwall of isolating guide plate can be designed to zigzag structure.
The explanation that A, B in the accompanying drawing, C are 3; Mainly after installing the isolation guide plate additional, the change of concentrating abration position is narrated, the main wear point of its excurvation is at the A point, the A point is bearing the bump abrasive wear of whole powders in the pipe, elbow very short time is worn through, life-span is shorter, main wear point splits A, B 2 points simultaneously after installing the isolation guide plate additional, even the B point is worn out, but owing to isolate the kinetic energy effect of guide plate and powder 3, do not overlap with the A point by the powder wear point of isolating guide plate yet, and, make the relative uniform wear of excurvation thus at C point place.
Claims (3)
1, a kind of wind powder Wear-proof bend is characterized in that installing additional in elbow and isolates guide plate (2), and up and down between the tube wall, bend angle is consistent with angle of bend in elbow for it.
2, according to the described wind powder pipe Wear-proof bend of claim 1, feature is to isolate the position that guide plate (2) can be arranged near partially excurvation (1) in the elbow.
3, according to the described wind powder pipe Wear-proof bend of claim 1, feature is to be designed to saw tooth structure with isolating guide plate (2) and excurvation (1) inwall.
