Abstract
The utility model relates to a slurry pump cover which comprises a cover body (1); an inlet (3) is formed in the cover body (1); a flange interface (2) is connected to the inlet (3); a mounting hole (4) is formed in the flange interface (2); the slurry pump cover is characterized in that the inlet (3) is connected with the flange interface (2) through a connecting part (5); the connecting part (5) adopts a tubular structure; one end of the connecting part (5) is communicated with the inlet (3), and the other end of the connecting part (5) is communicated with the flange interface (2); and the mounting hole (4) is an unthreaded hole. The utility model provides the slurry pump cover which is lower in maintenance cost.
Description
Technical field
The utility model relates to slag stock pump accessory technical field, specifically is meant a kind of slag stock pump lid.
Background technique
The slag stock pump is widely used in the existing technology; A slag stock pump slag input slurry mouthful place generally is provided with pump cover; With shown in the accompanying drawing 2, slag stock pump lid of the prior art comprises lid 1 ' like accompanying drawing 1, and lid 1 ' is provided with import 3 '; Be connected with flange-interface 2 ' in the import 3 ', the flanged surface of flange-interface 2 ' is provided with threaded mounting hole 4 '.The slag stock pump is connected in the slag stock tank through flange-interface 2 ', so also need connect one flanged connecting tube on the flanged surface of flange-interface 2 ' in use.The slag stock pump of this structure lid in the existing technology, flange-interface 2 ' are to be set directly on the end face of lid 1 ', when reality is used; Be used for flange-interface 2 ' on the connecting tube that is connected of flanged surface to be connected on the flange-interface 2 ' and can only fix through screw directly is screwed in the mounting hole 4 '; As everyone knows, coming connecting tube with flanged surface is in order to guarantee the sealing of pipeline, puts in place so need tighten during the screw rod on twisting flange; But repeatedly twist the risk that screw rod just has stripped thread repeatedly; Shown in accompanying drawing 1, if the 4 ' stripped thread of the mounting hole on the flange-interface 2 ', whole flanged surface just can't re-use; Can only pump cover all be changed, the maintenance cost of the slag stock pump lid of obvious this structure is too high.
The model utility content
The technical problem that the utility model will solve is to provide a kind of maintenance cost lower slag stock pump lid.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: a kind of slag stock pump lid, and it comprises lid; Lid is provided with import, is connected with flange-interface in the import, and flange-interface is provided with mounting hole; Described import links to each other with flange-interface through joint, and joint is a tubular structure, and an end of joint is communicated with import; The other end of joint is communicated with flange-interface, and described mounting hole is a unthreaded hole.
After adopting above structure, the utlity model has following advantage: described import links to each other with flange-interface through joint, and joint is a tubular structure, and an end of joint is communicated with import, and the other end of joint is communicated with flange-interface.This structure makes between flanged surface and the lid of flange-interface has had certain fit up gap; Flange-interface can be connected with flanged surface on the connecting tube through bolt like this; That is to say in the mounting hole on the flange-interface screw thread not to be set, get final product through nut check after directly screw rod being passed the flanged surface of flange-interface and connecting tube.The problem that can not have described mounting hole screw thread stripped thread like this even stripped thread also only can occur on the screw rod or nut of bolt, only needs to change bolt this moment and gets final product, and the maintenance cost of the slag stock pump lid of obvious this structure is lower.
As preferably, described joint and lid are one-body molded through casting technique.The steadiness that this structure can be guaranteed whole slag stock pump lid has also saved the welding process between joint and the lid simultaneously, has improved manufacturing efficiency.
Preferred as further, the length of described joint is 5～15cm.This length can adapt to most bolt, and assembling capacity is better.
Description of drawings
Fig. 1 is the structural representation of slag stock pump lid in the existing technology.
Fig. 2 is the A-A face cross-sectional schematic of slag stock pump lid in the existing technology.
Fig. 3 is the structural representation of slag stock pump lid in the utility model.
Fig. 4 is the A-A face cross-sectional schematic of slag stock pump lid in the utility model.
As shown in the figure: in the existing technology: 1 ', lid, 2 ', flange-interface, 3 ', import, 4 ', mounting hole, in the utility model: 1, lid, 2, flange-interface, 3, import, 4, mounting hole, 5, joint.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
In conjunction with accompanying drawing 3 and accompanying drawing 4, a kind of slag stock pump lid, it comprises lid 1; Lid 1 is provided with import 3, is connected with flange-interface 2 in the import 3, and flange-interface 2 is provided with mounting hole 4; Described import 3 links to each other with flange-interface 2 through joint 5, and joint 5 is a tubular structure, and an end of joint 5 is communicated with import 3; The other end of joint 5 is communicated with flange-interface 2, and described mounting hole 4 is a unthreaded hole.Described joint 5 is one-body molded through casting technique with lid 1.The length of described joint 5 is 5～15cm.Can the length of joint 5 be made as 10cm during practical implementation.
More than the utility model and mode of execution thereof are described, this description does not have restricted, also one of the mode of execution of the utility model just shown in the accompanying drawing, practical structure is not limited thereto.If generally speaking those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim,, all should belong to the protection domain of the utility model without creationary mode of structure similar and the embodiment of designing with this technological scheme.
