Description
Technical Field
The invention relates to the field of cutters. In particular to a cutter for cleaning a flange water-textured surface sealing gasket.
Background
In the practical production application, the flange gate is installed on the pipeline, the flange on one side of the flange gate and the flange on the pipeline form a flange water texture surface, and the asbestos pad is installed between the flange water texture surfaces and fastened through the bolts to play a role in sealing the flange water texture surfaces. However, asbestos pads have a certain service life and when they fail, they need to be replaced with new ones. Before replacing a new asbestos pad, the old asbestos pad between the flange water texture surfaces must be cleaned, otherwise, the remaining asbestos pad can not keep the flange water texture surfaces flat, and the new asbestos pad can not play a role in sealing due to the fact that the flange water texture surfaces are not flat, and finally pipeline leakage is caused.
At present, when the asbestos pad is replaced, if the old asbestos pad needs to be thoroughly cleaned, the best method is to disassemble the whole flange gate so as to ensure good cleaning conditions. However, due to the limitation of the actual production process, the flange gate cannot be detached at will, and the old asbestos pad can be cleaned in the narrow space between the two flanges only after the bolts on the flange on one side of the flange gate are detached.
However, since the space between the two flanges is narrow, when non-professional tools such as a screwdriver and a saw blade are used for cleaning, the old asbestos pad attached to the water wave surface of the flange is difficult to clean due to the fact that an operator cannot exert force. Especially when the operation environment illumination is not enough, lead to the operator to clear up the degree of difficulty and increase, the clearance effect can't guarantee more. Therefore, the phenomenon that the flange water wave surface leaks quickly due to unevenness after a new asbestos pad is added is easy to occur due to poor cleaning effect.

The end surface of the fourth blade body 19 of the second fish-scale blade 13 may be in any shape, and in the embodiment of the present invention, the end surface of the fourth blade body 19 of the second fish-scale blade 13 is not specifically limited; for example, the end surface of the fourth blade body 19 of the second fish scale blade 13 may be triangular or quadrangular. Preferably, the end surface of the fourth blade body 19 of the second fish scale blade 13 is triangular.
It should be noted that, when the size and the structure of the first fish-scale knife 9 are the same as those of the second fish-scale knife 13, the end surfaces of the third knife body 18 and the fourth knife body 19 are also the same and are both acute triangles.
In another point to be described, the design of the scale blade of the first scale knife 9 and the design of the scale blade of the second scale knife 13 are beneficial to cleaning the old asbestos pad, so that the frictional resistance of the cutter for cleaning the flange water-textured surface sealing gasket is reduced, and the old asbestos pad is thoroughly cleaned.
In a possible implementation manner, the connection among the parts of the cutter for cleaning the flange water-textured surface sealing gasket can be any one, and in the embodiment of the invention, the connection among the parts of the cutter for cleaning the flange water-textured surface sealing gasket is not particularly limited; for example, the connection between the parts of the cutter for cleaning the flange water-textured surface sealing gasket can be integrally formed by injection molding or welding. Preferably, the connection between all parts of the cutter for cleaning the flange water-textured surface sealing gasket is integrally formed by injection molding.
In a possible implementation manner, the material of the first tool bit 10 and the material of the second tool bit 14 may be set and changed as needed, and in the embodiment of the present invention, the material of the first tool bit 10 and the material of the second tool bit 14 are not particularly limited; for example, the material of the first cutting head 10 and the material of the second cutting head 14 may be metallic iron, metallic copper, or an alloy. Preferably, the material of the first cutting head 10 and the material of the second cutting head 14 are alloys.
It should be noted that, when the material of the first tool tip 10 and the material of the second tool tip 14 are made of alloy, the hardness of the first tool tip 10 and the hardness of the second tool tip 14 are increased, which is beneficial to thoroughly cleaning the old asbestos pad, and simultaneously, the service lives of the first tool tip 10 and the second tool tip 14 are also prolonged.
When the cutter for cleaning the flange water-textured surface sealing gasket provided by the embodiment of the invention is used, as shown in fig. 3, after bolts on flange gates and pipeline flange surfaces are taken down from bolt holes 22, the flange plates are pried by a prying bar, water spraying treatment is carried out on an old asbestos pad, butter is coated on the upper boss 6 and the lower boss 7 of the limiting disc 1, then the cutter for cleaning the flange water-textured surface sealing gasket is placed into the flange plates on two sides, the upper boss 6 enters the flange plate 20 to be cleaned, and the lower boss 7 enters the flange plate to be cleaned on the other side. When the crow bar is loosened, the flange plates on the two sides can press and clean the cutter for the flange water-grained surface sealing gasket under the action of the original structural force. The scraping operation is firstly carried out by utilizing the first scraping knife 8 and the second scraping knife 12, the first knife handle 4 and the second knife handle 5 are rotated and force is applied to the flange water texture surface 21 to be scraped, and the old asbestos pad begins to be crushed under the action of the first knife head 10 and the second knife head 14 with conical structures. The first knife handle 4 and the second knife handle 5 are rotated reversely, the first fish scale knife 9 and the second fish scale knife 13 are tightly attached to the flange water texture surface 21, the attached broken old asbestos pads are shoveled away from the flange water texture surface 21 until only the friction sound between the knife for cleaning the flange water texture surface sealing gasket and the flange water texture surface 21 is heard in the whole rotating process, and at the moment, the old asbestos pads on the flange water texture surface 21 on the side are cleaned. And (3) prying the flange plates on the two sides by using a crow bar, taking out the cutter for cleaning the flange water-textured surface sealing gasket, reversely putting the cutter into the flange plates on the two sides, and cleaning the flange water-textured surface 21 on the other side until the flange water-textured surface is cleaned up. The cutter for cleaning the flange water-textured surface sealing gasket improves the cleaning efficiency of the flange surface. The crushing operation of the old asbestos pad is realized by the cone-shaped protruding structure of the first cutter head 10 and the cone-shaped protruding structure of the second cutter head 14, and the residual old asbestos pad is thoroughly removed while the friction resistance is reduced by the scale blades of the first scale knife 9 and the scale blades of the second scale knife 13, so that the leakage phenomenon caused by the unevenness of the flange water mark surface 21 is avoided.
The above description is only for facilitating the understanding of the technical solutions of the present invention by those skilled in the art, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
