Abstract
The utility model discloses an interference type wear resistant pipe elbow. The pipe wall at the outer arc of the elbow body is provided with small hole which is communicated with the inner cavity of the elbow body. The utility model is characterized in that the pipe wall at the outer arc of the elbow body is provided with small hole which is communicated with the inner cavity of the elbow body, when the gas through the small hole enters the abrasion area in the inner cavity of the elbow, the particle flowing in the area is interfered so as to block and damage the flow track of the high-speed particle flow and reduce the flow speed at the inner wall surface of pipe to form a protection air-cushion to slow down the wear of the elbow. In actual application, the position and quantity of the small hole can differ according to the diameter of the pipe elbow, and a small hole or two separate small holes can be arranged. The utility model has the advantages of simple structure, easy processing and basically does not increase the cost of the existing elbow. When the wear resistance measures are not needed, the small hole can be jammed and used as a general elbow.
Description
Technical field
The utility model relates to the pipeline connecting bend, especially relates to the wear-resisting pipe bend of using in a kind of conveying powder material pipeline of wind-disturbant type.
Background technique
In the powder feeding pipes system of coal-burning power plant, connecting bend is indispensable, during work, the pulverized coal flow that flows in the pipeline is when the elbow arc section, because action of centrifugal force, make wind powder melting concn strengthen at elbow inner chamber outer rim place, particle kinetic energy strengthens the striking force of tube wall thereupon, cause the transducer wall ' s abrasion at elbow cylindrical segmental arc place serious, greatly reduce the working life of elbow, the working life that makes wear-resisting pipe bend is well below former designing requirement, for addressing this problem, often take to increase the method for elbow external arc tube wall, but effect is undesirable.
The model utility content
The purpose of this utility model is to provide a kind of long-lived wind-disturbant type wear-resisting pipe bend.
For achieving the above object, the utility model can be taked following technical proposals:
The wear-resisting pipe bend of wind-disturbant type described in the utility model, it comprises the elbow body, it is characterized in that: offer the aperture that is connected with described elbow chamber body on the cylindrical segmental arc tube wall of described elbow body.
Described aperture is on two spaced apart cylindrical segmental arc tube walls that are located at described elbow body.
Advantage of the present utility model is to offer the aperture that is connected with described elbow chamber body on the tube wall of the exterior arc surface of elbow body, after the gas that feeds in the aperture enters elbow inner chamber eroded area, grain flow in this zone is interfered, thereby hinder and destroyed the flow trace of high-velocity particle stream, reduce the flow velocity of inner tube wall surface, form the protection air cushion, the wearing and tearing of elbow are alleviated; In actual applications, offer the position of aperture and size that quantity is looked the elbow caliber and different, can offer an aperture or offer two at interval.The wear-resisting pipe bend of wind-disturbant type described in the utility model is simple in structure, is easy to processing, does not increase the cost of existing elbow substantially, in the time need not adopting the abrasionproof measure, aperture can be blocked up and promptly can be used as general elbow use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, the wear-resisting pipe bend of wind-disturbant type described in the utility model comprises elbow body 1, spaced apartly on the cylindrical segmental arc tube wall of described elbow body 1 is provided with two apertures 2 with elbow body 1 intracavity inter-connection.
Claims (2)
1, the wear-resisting pipe bend of a kind of wind-disturbant type, it comprises elbow body (1), it is characterized in that: offer the aperture (2) with described elbow body (1) intracavity inter-connection on the cylindrical segmental arc tube wall of described elbow body (1).
2, the wear-resisting pipe bend of wind-disturbant type according to claim 1 is characterized in that: described aperture (2) is two, on the spaced apart cylindrical segmental arc tube wall that is located at described elbow body (1).
