Abstract
The utility model relates to a novel adjusting nut for an anti-reversion device, which comprises an anti-reversion end cap, an adjusting nut, a pump coupling, a screw and a shaft, and is characterized in that an outward-extending disk is arranged at one end of the adjusting nut, an installation hole is arranged on the disk, and the adjusting nut is connected with the anti-reversion end cap through a screw located in the installation hole. The novel adjusting nut for the anti-reversion device has the advantages that the debugging space and the installation space of the adjusting nut are increased, the pump coupling does not need removing, the novel adjusting nut can be installed and debugged on the original places, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of adjustment nut, particularly a kind of novel adjustment nut that is used for anti-reverse mechanism.
Background technique
Vertical sewage pump is easy to form counter-rotating when starting, so the counter-rotating will prevent starting mode of pump with anti-reverse mechanism the time.Adjusting nut is a part of anti-reverse mechanism, and its effect mainly contains two: the one, compress anti-reverse end cap, and the 2nd, adjust axial string quantity.Because adjusting nut one end is the pump coupling, when the distance between itself and the pump coupling is big inadequately, adjust axial string quantity, adjustment and operating space are not enough, then the pump coupling must be removed, this will bring inconvenience to Installation and Debugging and maintenance, influence working efficiency.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of the used adjustment nut of anti-reverse mechanism in the prior art, and a kind of novel adjustment nut that is used for anti-reverse mechanism is provided.The utility model designs a kind of novel adjustment nut that is used for anti-reverse mechanism, comprise anti-reverse end cap, adjust nut, pump coupling, screw, axle, it is characterized in that: on an end of adjusting nut, be provided with an overhanging disk, on disk, offer mounting hole, adjust nut and connect anti-reverse end cap by the screw that is positioned at mounting hole.The utility model has the advantages that to make debug space, the installing space of adjusting nut increase,, just can carry out Installation and Debugging in the original place, improved manufacturing efficiency so do not need the pump coupling of dismantling.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is the original structure schematic representation; Accompanying drawing 2 is a structural representation of the present utility model;
Embodiment
Comprise anti-reverse end cap 1, adjustment nut 2, pump coupling 3, screw 4, axle 5 among the figure, it is characterized in that: on an end of adjusting nut 2, be provided with an overhanging disk 6, on disk 6, offer mounting hole 7, adjust nut 2 and connect anti-reverse end cap 1 by the screw 4 that is positioned at mounting hole 7.At big disk 6 of the lower end of former adjustment nut 2 processing, uniform processing goes out three mounting holes 7 on disk 6, and processes tapped hole on anti-reverse end cap 1 corresponding center hole.Like this, when adjusting axial string quantity, adjust the space and compare before, net increase the end face height of disk of two different-diameters, debug space, installing space are increased,, just can carry out Installation and Debugging in the original place so do not need the pump coupling of dismantling, thereby solved owing to adjusting the distance very little adjustment problem that have influence on axial string quantity of nut between joining with pump, used and maintenance provides convenience to the user.
