Abstract
The utility model relates to a butterfly valve transmission mechanism for metallurgy. The butterfly valve transmission mechanism comprises two connecting plates, a copper sleeve, a locking nut, a penetrating shaft and a steel sleeve, the connecting plates are connected with the penetrating shaft through the locking nut, the copper sleeve is arranged on the outer side of the penetrating shaft at a joint of the connecting plates, the steel sleeve is arranged on the outer side of the penetrating shaft between the connecting plates, the inner diameter of the steel sleeve is larger than the diameter of the penetrating shaft by 2mm, wall thickness of the steel sleeve is 4-6mm, and length of the steel sleeve is smaller than an interval of the connecting plates by 5mm. Compared with the prior art, the butterfly valve transmission mechanism has the advantages that the butterfly valve transmission mechanism is simple in structure, convenient to use and scientific and practical, service life of a butterfly valve is effectively prolonged, maintenance cost of the butterfly valve is saved, transmission stability of the butterfly valve is improved, production efficiency is improved, and the accident that the penetrating shaft retreats from a penetrating shaft hole due to loosening of the copper sleeve after being heated is avoided.
Description
Technical field
The utility model relates to fly valve technical field, particularly a kind of metallurgy fly valve driving mechanism.
Background technique
Fly valve is a kind of of throttle valve, the structure of this valve is the principle of pulling according to pipe gear, its flow control component is one to have the disk at inclination angle, disk is fixed in axle, and control switching with revolvable axle, this valve constitution is simple, its valve body is pancake type, lightweight, do not take up space and be suitable for the use of throttling and switching, be particularly useful for the control of large flow, but due to fly valve kinematic link and to wear axle different from copper sheathing material, thermal expansion coefficient is different, after causing copper sheathing loosening after being heated, wearing axle exits from wearing axis hole, changed the normal running orbit of fly valve, cannot normally realize switching function, hot blast stove cannot normal operation, cause blast furnace staying.
Summary of the invention
The purpose of this utility model is to provide a kind of stability of transmission, the metallurgy of enhancing productivity fly valve driving mechanism.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of metallurgy fly valve driving mechanism, comprise connecting plate, copper sheathing, locking nut, wear axle and steel bushing, described connecting plate has two, and by locking nut with wear axle and link together, the axle outside of wearing of connecting plate joint is provided with copper sheathing, and the axle outside of wearing between two connecting plates is provided with steel bushing.
The internal diameter of described steel bushing is greater than wears shaft diameter 2mm, and the wall thickness of steel bushing is 4-6mm, and the length of steel bushing is less than two connecting plate spacing 5mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of metallurgy fly valve driving mechanism, there is feature simple in structure, easy to use, science is practical, effectively raise the working life of fly valve, saved the maintenance cost of fly valve, strengthened the stability of fly valve transmission, improved manufacturing efficiency, avoided copper sheathing to be heated wearing axle after loosening from wearing axis hole, exiting the generation of accident.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
1-connecting plate, 2-copper sheathing, 3-locking nut 4-wear axle 5-steel bushing
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of metallurgy fly valve driving mechanism of the utility model, comprise connecting plate 1, copper sheathing 2, locking nut 3, wear axle 4 and steel bushing 5, described connecting plate 1 has two, and by locking nut 3 with wear axle 4 and link together, axle 4 outsides of wearing that axle 4 outsides are provided with between 2, two connecting plates 1 of copper sheathing of wearing of connecting plate 1 joint are provided with steel bushing 5; The internal diameter of described steel bushing 5 is greater than wears shaft diameter 2mm, and the wall thickness of steel bushing 5 is 4-6mm, and the length of steel bushing 5 is less than two connecting plates, 1 spacing 5mm.
While using the utility model, first by copper sheathing 2, locking nut 3, wear axle 4 and steel bushing 5 is arranged on connecting plate 1 successively, during hot blast stove operation, loosening even if copper sheathing 2 is heated, because the thermal expansion coefficient of steel bushing 5 is different, prevented from wearing axle 4 and exited in connecting plate 1.
Above described in be only basic principle of the present utility model, not the utility model is imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
Claims (2)
