Abstract
A removable wear resistant elbow structure is used for the fastening of the elbow of the transmission pipeline for solid or liquid hard and heavy material, belonging to the technical field of the manufacture of the elbow of the transmission pipeline for hard and heavy material. The utility model adopts a removable design proposal and provides a removable wear resistant elbow structure with changeable pipe wall, comprising an elbow body, an elbow cover plate and a window at the bending part of the elbow. The bending degree of the elbow cover plate is the same as that of the elbow window, and the elbow cover plate and the elbow window are connected by a bolt, thus solving the problems that the existing elbow needs to be changed wholly after being worn and avoiding the waste. The utility model adopts the removable plate structure which can be changed rapidly if being worn, and at the same time, the removable plate are thickened or made of abrasion resistant material, so as to prolong the service life of the removable plate and reduce the cost of anti-wear performance.
Description
Technical field:
A kind of removable wear bend pipe structure is used for the swiftly flowing solid-state and liquid reinforcing of heavy substance conveyance conduit bend pipe firmly, belongs to the manufacturing technology field of hard heavy substance conveyance conduit bend pipe.
Background technique:
In the prior art, be used to carry the conveyance conduit of various media, owing to landform and the reason that the position is set all need to turn, the elbow material that is used for these pipelines at present all is and the straight tube identical materials basically, especially for the pipeline of carrying swiftly flowing solid-state and liquid two-phase material, use and the making of straight tube identical materials in pipe bent position, because at the turning, the material that flows is subjected to stopping of bend fast, so wear phenomenon is very serious; The technology that addresses this is that at present is 99224133.2 by the patent No., 94215395.2, CN85104756A, 02151748.7 and 00235090.4 patented technology is representative, mainly be the thickness that increases wearing part, select high-abrasive material for use, with the three kinds of technology of structure that change bend pipe, these technical measures can effectively be improved the wear condition of bend pipe, prolong the working life of pipeline, but, no matter take which kind of measure, because flowing medium washes away fast, pipe bent position is the weak link of pipeline all the time, increase the thickness of bend pipe and adopt high-abrasive material also just temporarily to prolong the time of using, but its manufacture cost also raises greatly simultaneously, and, can only change bend pipe in case the whole bend pipe in worn out back just can not use; Particularly when carrying out air drilling, the landwaste that the down-hole is taken out of washes away very serious to the sediment outflow pipeline elbow in well site, change the workload that bend pipe need cost a lot of money, and can carry out the replacing of bend pipe but also will stop to bore; In addition, because bend pipe is an integral body,, cause waste so local leakage also will all be changed.
Goal of the invention:
The purpose of this utility model is the problem that can not make full use of whole bend pipes at prior art, adopts removable design proposal, and a kind of dismantled and assembled abrasion-proof bent tube structure with replaceable tube wall is provided.
Realize like this during the utility model: the utility model comprises the bend pipe body, the bend pipe cover plate, curved section at bend pipe is offered window, the bend pipe cover plate is a crooked globoidal structure, the bend pipe cover plate is identical with the bend pipe window tortuosity of offering, and four limits of bend pipe cover plate are greater than four limits of bend pipe window, and the tube wall partial design of the easy wear and leakage of bend pipe is become the detachable plate structure, the Placement of dismounting plate and bend pipe can adopt bolt to be connected, and also can adopt the Placement of clip to connect; The dismounting plate is thickeied, perhaps selected for use high-abrasive material; The beneficial effects of the utility model and advantage are: adopted the disassembled and assembled freely plate structure, so in case wear and leakage appears in the dismounting plate, just can be rapidly with it replacing, simultaneously, owing to only the bend pipe cover plate has been carried out thickening or has selected high-abrasive material for use, so both prolonged the working life of dismounting plate, reduced the abrasionproof processing cost again.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a sectional view of the present utility model.
Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing: the utility model comprises bend pipe body 4, bend pipe cover plate 2 and bolt 1, bow face curved section at bend pipe body 4 is offered the bend pipe window, and terraced steps is set on bend pipe window four limits, bend pipe cover plate 2 is crooked globoidal structures, bend pipe cover plate 2 is identical with the bend pipe window tortuosity of offering, also be provided with and the corresponding terraced steps of bend pipe window on four limits of bend pipe cover plate 2 flexure planes, adopt bolt 1 to be connected between bend pipe cover plate 2 and the bend pipe window, bow face two ends at bend pipe cover plate 2 are provided with snap-ring groove 3, flexure plane and bend pipe cover plate 2 two ends snap-ring grooves 3 corresponding positions at bend pipe body 4 also are provided with snap-ring groove, and bend pipe cover plate 2 also can adopt clip to be connected with the bend pipe window; Mode of execution is: select for use high-abrasive material to make the bend pipe cover plate 2 of thickening, ready bend pipe cover plate 2 trapezoidal lifted the rank alignment to be arranged in the terraced steps on bend pipe window four limits, bend pipe cover plate 2 is fixed on the installation of just having finished bend pipe cover plate 2 on the bend pipe window by bolt 1 then, in order to improve the speed of changing bend pipe cover plate 2, also clip can be placed in the snap-ring groove 3 around the flexure plane of bend pipe cover plate 2, bend pipe cover plate 2 is fixed on the bend pipe body 4; In wellbore construction, perhaps after one section well has been bored, washed out by landwaste if find bend pipe cover plate 2, in the time of can not continuing to use again, bend pipe cover plate 2 be unloaded, change standby bend pipe cover plate, and can continue after fixing to implement to creep into.
Claims (5)
1. a dismantled and assembled abrasion-proof bent tube structure comprises bend pipe body and bend pipe cover plate, it is characterized in that: the bow face curved section at the bend pipe body offers the bend pipe window, and the bend pipe cover plate is a crooked globoidal structure, and the bend pipe cover plate is connected by bolt with the bend pipe window.
