Including equipment flange I, equipment flange II, weld ring II and weld ring I, weld ring I and equipment flange I welding, weld ring II and equipment flange II welding, it has the annular seal groove to open on equipment flange I's the ring I that welds, O type sealing washer is packed into in the annular seal groove, O type sealing washer compresses tightly it by welding ring II on the equipment flange II, be connected with double-screw bolt and nut between equipment flange I and the equipment flange II, extrude when screwing up the nut and weld ring I and weld ring II, thereby extrude O type sealing washer simultaneously and guarantee the good sealing performance of sealed face, weld ring I and weld ring II's contact segment welding. The utility model has the advantages that: through the O-shaped sealing ring welded sealing flange structure, the leakage problem of equipment during a hydrostatic test and after the equipment is driven to a field is effectively solved, and the safe and effective sealing of the equipment body is realized.
Description
Technical Field
The utility model relates to a chemical industry equipment technical field flange seal face transformation technique specifically is a there is O type sealing washer welded seal flange structure.
Background
In a plurality of chemical equipment, due to various reasons such as structural limitation, manufacturing factors or process requirements and the like, the diameter of the equipment is often large, when the pressure is medium and high pressure and the equipment flange is required to be provided, the sealing performance of the equipment flange is often the key point of the design and the manufacture of the equipment. The gasket-free welded seal needs higher-precision machining equipment and higher technical level of a manufacturing unit, and generally, leakage and sealing failure of a sealing surface are easy to occur when a hydrostatic test and field operation are carried out after the equipment is manufactured, so that the improvement of the gasket-free welded seal structure is very necessary for reducing the leakage of the equipment and ensuring the effective sealing, and the loss of various manpower, material resources and financial resources caused by solving the problem of the leakage of the equipment or the sealing failure in the field can be reduced by improving the gasket-free welded seal structure.
Disclosure of Invention
The utility model provides a because of make, processing equipment condition is limited, the unable sealed problem of equipment leakage when using no gasket welded seal flange structure has realized the good sealing of equipment body.
The utility model discloses an adopt following technical scheme to realize: the utility model provides a there is O type sealing washer welded seal flange structure, including equipment flange I, equipment flange II, weld ring II and weld ring I, weld ring I and equipment flange I welding, weld ring II and equipment flange II welding, it has the ring seal groove to open on equipment flange I's weld ring I, O type sealing washer is packed into in the ring seal groove, O type sealing washer compresses tightly it by welding ring II on the equipment flange II, be connected with double-screw bolt and nut between equipment flange I and the equipment flange II, extrude when screwing up the nut and weld ring I and weld ring II, thereby extrude O type sealing washer simultaneously and guarantee the good sealing performance of sealed face, weld ring I and weld ring II's contact segment welding.
The sealing flange structure with the O-shaped sealing ring for welding is characterized in that the right angle of the bottom of the annular sealing groove is rounded and smoothly transited.
The utility model has the advantages that: through the O-shaped sealing ring welded sealing flange structure, the leakage problem of equipment during a hydrostatic test and after the equipment is driven to a field is effectively solved, the safe and effective sealing of the equipment body is realized, and meanwhile, the failed O-shaped sealing ring is convenient to replace, so that the sealing structure can be safe and effective for a long time, and the safe and stable operation of the equipment is ensured.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged view of a portion a of fig. 1.
In the figure: 1-equipment flange I, 2-stud, 3-nut, 4-equipment flange II, 5-welding ring II, 6-welding ring I,7-O type sealing ring I, 8-O type sealing ring II.
Detailed Description
As shown in the figure, the O-shaped sealing ring welding sealing flange structure consists of an equipment flange I1, a stud 2, a nut 3, an equipment flange II4, a welding ring II5, a welding ring I6, an O-shaped sealing ring I7 and an O-shaped sealing ring II 8.
Two annular sealing grooves are radially formed in a welding ring I6 of an equipment flange I1, the right angle of the bottom of each annular sealing groove is in round and smooth transition, an O-shaped sealing ring I7 and an O-shaped sealing ring II 8 are arranged in each annular sealing groove, the upper parts of the O-shaped sealing ring I7 and the O-shaped sealing ring II 8 are pressed tightly by using a welding ring II5 on an equipment flange II4, a welding ring II5 is welded with an equipment flange II4, the welding ring I6 is welded with the equipment flange I1, the equipment flange I1 is connected with the equipment flange II4 by using a stud 2 and a nut 3, the nut 3 is screwed, the welding ring I6 and the welding ring II5 are pressed, the O-shaped sealing ring I7 and the O-shaped sealing ring II 8 are pressed simultaneously, good sealing performance of a sealing surface is guaranteed, and finally, a contact part of the welding ring I6 and the welding ring II5 is welded, and double insurance is.
