Abstract
The utility model belongs to a pump connection device and in particular relates to a loose flange for connecting a connection pipe and a pump body of an abrasion pump used in industries including chemical engineering, metallurgy, coal, papermaking, pharmacy, environmental protection and the like. The loose flange is formed by an inner ring flange and an outer ring flange. An inner hole of the inner ring flange is provided with a taper communicated with a pump body connection pipe, an inner hole of the outer ring flange is matched with the external diameter of the inner ring flange to be installed, and the inner ring flange is in welded connection with the outer ring flange at a jointing position. The loose flange is simple in structure, and resolves the problems that the machining difficulty of a connecting hole arranged on the pump body is large, the assembling angle in assemble can not be adjusted, and the assembling requirements of users at site can not be satisfied.
Description
Technical field
The utility model belongs to a kind of pump class connection set, is specially adapted to the abrasion pump pump housing that industries such as chemical industry, metallurgy, coal, papermaking, pharmacy, environmental protection use and takes over the lap joint flange that is connected.
Background technique
At present, the abrasion pump finds that in its machine adds and assembles traditional pump housing and flange are an integral body, because the specific (special) requirements on the purposes, the hardness of the pump housing is very high, and the difficulty of processing of its pilot hole is very big; Be exactly in addition the pump housing and flange be an integral body because the pilot hole angle has been fixed,, caused can't satisfying sometimes client's assembled in situ requirement so in assembly process, be not easy to regulate.Therefore, at above two problems, should be in the transformation of carrying out on the basis of original pump housing on the corresponding construction.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of pump lap joint flange, it is simple in structure, and angle of assembling can't be regulated when having solved the difficulty of processing of attachment hole on the pump housing and assembling, can't satisfy the problem of curstomer`s site matching requirements.
The technological scheme that solution the utility model technical problem is taked is: flange is made up of inner ring flange and outer ring flange, the endoporus of inner ring flange has with the pump housing takes over the tapering that communicates, the endoporus of outer ring flange cooperates installation with the external diameter of inner ring flange, and is welded to connect at the two seaming position.
The fitting surface of described inner ring flange and outer ring flange is provided with corresponding nested step, and the outside of the two seam is along circumferentially being evenly distributed with a plurality of gap, and the electric welding link position is in the gap position.
Described inner ring flange be two halves to opening structure, inner ring flange and outer ring flange adopt interference fit.
The beneficial effects of the utility model are: the processing of lap joint flange, dismounting, adjustment are very all very convenient.The machine of greatly reducing adds and assembling difficulty, and has saved the time.
Description of drawings
Fig. 1 is a side-looking structural representation of the present utility model.
Fig. 2 is the structural representation of facing of the present utility model.
Among the figure: inner ring flange 1, attachment hole 2, outer ring flange 3, solder joint 4, the pump housing take over 5.
Embodiment
As shown in the figure: the endoporus of inner ring flange 1 has with the pump housing takes over 5 taperings that communicate, and the endoporus of outer ring flange 3 cooperates installation with the external diameter of inner ring flange 1, and is welded to connect at the two seaming position.The fitting surface of inner ring flange 1 and outer ring flange 3 is provided with corresponding nested step, and the outside of the two seam is solder joint 4 along circumferentially being evenly distributed with eight gap with the gap, and inner ring flange 1 and outer ring flange 3 are fixed as one.Inner ring flange 1 is that two halves are to opening structure, so that be assembled in the pump housing adapter 5 inner ring flange 1 and outer ring flange 3 employing interference fit.
During installation, earlier inner ring flange 1 is set to the pump housing and takes on 5, inner ring flange 1 and outer ring flange 3 are connected again, then six gap are carried out spot welding, the weld joint is polished flat gets final product at last.
Claims (3)
1. pump lap joint flange, it is characterized in that: flange is made up of inner ring flange and outer ring flange, the endoporus of inner ring flange has with the pump housing takes over the tapering that communicates, and the endoporus of outer ring flange cooperates installation with the external diameter of inner ring flange, and is welded to connect at the two seaming position.
2. by the described pump lap joint flange of claim 1, it is characterized in that: the fitting surface of inner ring flange and outer ring flange is provided with corresponding nested step, and the outside of the two seam is along circumferentially being evenly distributed with a plurality of gap, and the electric welding link position is in the gap position.
