Description
The technical field is as follows:
the utility model relates to a coal coking production technical field, concretely relates to a misloading prevention device for coke oven gas exchange cock.
Background art:
the coke oven heating gas exchange cock needs to be periodically disassembled for cleaning and maintenance due to the reason of working environment, when the coke oven heating gas exchange cock is installed again, when an identifier is fuzzy or an installer is neglected in operation, the phenomenon of wrong installation of the cock direction can occur, stagnant gas leaks, even explosion accidents can occur when the cock is serious, and huge potential safety hazards exist; however, this structure has the following disadvantages: the square of cock spanner needs frequent wrench in the use, and square bulge is the impetus that mainly receives the shearing force, and the junction stress of square bulge and cock is too big, leads to square bulge to be very easily worn and torn even produce the phenomenon of rupture, simultaneously, because the space is less, there is the difficulty in the welding of locating pin, and the size of locating pin is little, the alignment difficulty of locating pin and opening during the installation, the installation effectiveness is low.
The utility model has the following contents:
the utility model aims to provide an anti-misloading device for a coke oven gas exchange cock.
The content of the utility model is as follows: the wrong installation preventing device comprises a valve body and a cock wrench, wherein a cock core is installed in the valve body, a first screw hole and a second screw hole are formed in the outer end surface of the cock core, the first screw hole and the second screw hole are different in aperture, a first positioning column is connected in the first screw hole in a threaded mode, a second positioning column is connected in the second screw hole in a threaded mode, the first positioning column and the second positioning column are different in outer diameter, a first positioning through hole and a second positioning through hole are formed in the cock, the first positioning through hole is in clearance fit with the first positioning column, the second positioning through hole is in clearance fit with the second positioning column, and both ends of the first positioning column and the second positioning column are provided with hexagonal grooves.
Further, the thread turning directions of the first screw hole and the second screw hole are opposite.
Furthermore, the outer edges of the top ends of the first positioning column and the second positioning column are provided with guide angles.
The utility model has the advantages that: the utility model discloses simple structure utilizes the location structure of two points formula to guarantee the uniformity of cock and cock handle installation, and the position spiro union of two locating pins is in the terminal surface rather than the side, and installation space is big, and the locating pin size is big, and the location is more accurate, installation and dismantlement convenient and fast, even the locating pin breaks off, also can easily take off, and convenient and fast is changed to the locating pin, is worth using widely on a large scale.
Description of the drawings:
fig. 1 is a perspective view of the present invention;
fig. 2 is a cross-sectional view of the present invention;
in the figure, a valve body 1, a cock wrench 2, a cock core 3, a first screw hole 4, a second screw hole 5, a first positioning column 6, a second positioning column 7, a first positioning through hole 8, a second positioning through hole 9 and a hexagonal groove 10.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, the anti-misassembly device for the coke oven gas exchange cock comprises a valve body 1 and a cock wrench 2, wherein a cock core 3 is arranged in the valve body 1, a first screw hole 4 and a second screw hole 5 are arranged on the outer end surface of the cock core 3, the first screw hole 4 and the second screw hole 5 have different apertures, a first positioning column 6 is screwed in the first screw hole 4, a second positioning column 7 is screwed in the second screw hole 5, the outer diameters of the first positioning column 6 and the second positioning column 7 are different, a first positioning through hole 8 and a second positioning through hole 9 are formed in the cock wrench 2, the first positioning through hole 8 is in clearance fit with the first positioning column 6, and the second positioning through hole 9 is in clearance fit with the second positioning column 7, both ends of the first positioning column 6 and the second positioning column 7 are provided with hexagonal grooves 10; the screw thread directions of the first screw hole 4 and the second screw hole 5 are opposite; and guide angles are arranged on the outer edges of the top ends of the first positioning column 6 and the second positioning column 7.
The working principle is as follows: during installation, the first positioning through hole 8 and the second positioning through hole 9 are respectively sleeved in the first positioning column 6 and the second positioning column 7, so that the uniqueness of assembly is realized, the error installation is prevented, when the first positioning column 6 and the second positioning column 7 are broken under the action of shearing force for a long time, the hexagonal groove 10 positioned at the inner end is exposed, the positioning column can be easily taken out, and the positioning column can be replaced with a new positioning column.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
