Description
Technical Field
The utility model belongs to the technical field of sealing of metallurgical vacuum equipment, and particularly relates to an open sealing structure for an RH split type vacuum tank.
Background
The RH split type vacuum tank system comprises a hot bent pipe, a vacuum tank body and a suction nozzle. The vacuum tank body is respectively connected with the hot bent pipe and the suction nozzle, flange welding is adopted between the lower surface of the tank body and the suction nozzle, and the center distance and the verticality of the suction nozzle are ensured by positioning the flange; the upper surface of the tank body is connected with the hot bent pipe by a flange; the flange connection is sealed by means of the high-temperature-resistant O-shaped rubber ring, the sealing ring is fixed in the flange groove, and the flange is provided with a concave groove for installing the high-temperature-resistant O-shaped rubber ring.
The concave groove machining has the defects of high difficulty and high cost, and when the sealing structure is used, foreign matters such as steel slag and the like are easy to enter the concave groove, the sealing ring is easy to damage, the phenomenon of gas leakage which is difficult to find is caused, and the maintenance is inconvenient during operation.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the open sealing structure for the RH split type vacuum tank, and the technical effect of convenient maintenance during operation is achieved while the sealing effect is ensured by designing the open sealing structure.
The technical scheme adopted by the utility model is as follows: the utility model provides an open seal structure for RH split type vacuum tank, includes plane flange and the sealing washer of taking the location tang flange and setting up in location tang department that mutually support, form open sealing washer mounting groove in location tang department when plane flange and taking the location tang flange location to connect, the cross-section of sealing washer is the combination shape that upper semicircle, lower rectangle constitute, upper semicircle centre of a circle is established in the central point on the long limit of rectangle down.
Further, the ratio of the diameter of the upper semicircle to the length of the long side of the lower rectangle is 0.5-0.8:1.
further, the ratio of the section height of the sealing ring to the height of the installation groove of the open sealing ring is 1.17-1.5:1.
further, the sealing ring is made of silicon rubber with surface composited with ceramic fibers.
Further, the surface roughness of the sealing ring is 3.2-6.3.
The utility model has the beneficial effects that: the utility model adopts the open type sealing ring mounting groove formed by combining and mounting the flange with the positioning spigot and the plane flange, and the sealing ring is formed by an upper semicircle and a lower rectangle in the matched section, so that the sealing requirement is met, the on-site quick mounting of the sealing ring can be realized, more outer surfaces of the sealing ring can be observed during on-site maintenance, the foreign matters of the sealing ring can be conveniently cleaned, the on-site maintenance omission is reduced, and the maintenance efficiency is improved. The contact surface between the bottom surface of the sealing ring and the flange with the positioning spigot is increased, so that the sealing ring can better keep a fixed position; the upper surface of the sealing ring is semicircular, so that the easy-compression characteristic of the sealing ring is ensured; the flange does not need concave grooves, so that sundries are not easy to contain, and meanwhile, the process difficulty is reduced.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
The technical scheme will be clearly and completely described below with reference to the embodiments of the present utility model and the accompanying drawings.
Fig. 1 is a semi-sectional view of the installation state of the sealing ring 3 when the face flange 1 and the flange 2 with the positioning spigot are not pressed. The utility model provides an open seal structure for RH split type vacuum tank, includes plane flange 1 and the area location tang flange 2 of mutually supporting and sets up the sealing washer 3 in location tang department, plane flange 1 forms open sealing washer mounting groove in location tang department when taking location tang flange 2 location to connect, the cross-section of sealing washer 3 is the combination shape that upper semicircle, lower rectangle constitute, upper semicircle centre of a circle is established in the central point of the long limit of rectangle down.
The ratio of the upper semicircular diameter of the sealing ring 3 to the length of the long side of the lower rectangle is 0.5-0.8:1. the proportion is set to ensure the easy compression characteristic of the sealing ring 3, and the semicircular extrusion deformation amount is increased on the basis of not greatly changing the integral deformation of the sealing ring 3.
The ratio of the section height of the sealing ring 3 to the height of the installation groove of the open sealing ring is 1.17-1.5:1. the proportion is set to ensure good filling degree and friction force of the sealing ring 3 in the open sealing ring mounting groove, and the sealing performance of the sealing ring 3 is ensured as a whole.
The sealing ring 3 is made of silicon rubber with surface composited with ceramic fibers. The surface roughness of the sealing ring 3 is 3.2-6.3. The reasonable surface roughness setting can increase the frictional force between sealing washer 3 and the open sealing washer mounting groove, and then strengthen sealed effect.
In the concrete implementation, the flange 2 with the locating spigot and the flange 1 with the locating spigot are in locating connection with an open type sealing ring installation groove, so that the foreign matters falling on the periphery of the sealing ring 3 can be cleaned conveniently while the field installation and the inspection of the sealing ring 3 are facilitated.
The lower part of the cross section of the sealing ring 3 is rectangular, and the contact surface between the rectangular bottom surface and the contact plane of the positioning spigot is large, so that the sealing ring 3 can be well kept at the mounting position; the upper structure of the sealing ring 3 is semicircular, so that the better compressible characteristic of the sealing ring 3 is ensured, and when the section of the sealing ring 3 is installed in an open sealing ring installation groove, the better filling degree and friction force can be ensured, and the component connection sealing requirement of the RH split type vacuum tank is met.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
