Abstract
The utility model discloses an omega encircles seal structure with auxiliary seal circle, the right semi -ring that sets up including left semi -ring, with left semi -ring symmetry, left semi -ring and right semi -ring close the back periphery relatively and weld stitch fixation and connect two semi -rings, in the composition surface of left semi -ring and right semi -ring department, one side semi -ring is equipped with the boss, and the opposite side semi -ring is equipped with the recess that matches with the boss, the boss insert the recess in to the extrusion has the auxiliary seal circle in the recess. The utility model discloses an omega encircles seal structure with auxiliary seal circle, the periphery of two halves ring passes through welded connection, and faying face department clamping has the auxiliary seal circle. This sealing member centre gripping is between two subassemblies during the installation to half set method on the pass box is fixed with the bolt centre gripping. Be connected through the welding mode between every semi -ring and the subassembly. Have simple structure, convenient operation, sealed effectual, more be suitable for that few dismantlement or do not roll over is unloaded and the connection of high pressure and high temperature's big specification work piece is sealed.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly a kind of Ω ring sealing configuration with auxiliary seal ring.
Background technique
In manufacturing industry, sealed member is widely used, as all kinds of seal rings etc.Some sealed members there will be leakage when being subject to certain pressure, and existing various Sealing is not suitable for that two pieces is relatively fixing, seldom dismounting or the situation without the need to dismounting and high pressure-temperature.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, good sealing effect, the Ω ring sealing configuration with auxiliary seal ring that uses when to be particularly suitable for after installing without the need to dismantling, overcomes the deficiencies in the prior art.
Ω ring sealing configuration with auxiliary seal ring of the present utility model, comprise left semi-ring, with the symmetrically arranged right semi-ring of left semi-ring, left semi-ring and the right semi-ring rear perimeter edge that is involutory has weld seam to be fixedly connected with two described semi-rings;
At the mating face place of left semi-ring and right semi-ring, side is partly equipped with boss, and opposite side is partly equipped with the groove matched with boss, in the groove described in described boss inserts, and is extruded with auxiliary seal ring in groove.
Ω ring sealing configuration with auxiliary seal ring of the present utility model, the periphery of two semi-rings is by being welded to connect, and junction plane place clamping has auxiliary seal ring.During installation, this Sealing is clamped between two assemblies, and is gripped by the method on assembly half dish and bolt.Each semi-ring is connected by welding manner with between assembly.Have that structure is simple, easy to operate, good sealing effect, be more suitable for the connection sealing of the large-size workpiece of few dismounting or not demolition and high pressure-temperature.
Ω ring sealing configuration with auxiliary seal ring of the present utility model, manometer pressure be 30MPa, temperature is that the vessel flange sealing applications No leakage phenomenon of 500 DEG C occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: 1 is left connection part, and 2 is right connection part, be connected and fixed by the flange of termination and bolt after docking between two pieces.The Ω ring sealing configuration with auxiliary seal ring of the present utility model is had at the docking end clamping of two pieces, wherein 6 is left semi-rings, 4 is symmetrically arranged right semi-rings with left semi-ring, left semi-ring 6 and right semi-ring 4 rear perimeter edge that is involutory has weld seam 5 to be fixedly connected with two semi-rings, form cavity in the inner side of weld seam 5, the section of this sealing configuration is in approximate Ω shape.
At the mating face place of left semi-ring 6 and right semi-ring 4, side is partly equipped with boss 7, and opposite side is partly equipped with the groove matched with boss 7, and described boss 7 inserts in described groove, and in groove, be extruded with auxiliary seal ring 3.
During installation, this Sealing is clamped between two assemblies, and is gripped by the method on assembly half dish and bolt.Each semi-ring is connected by welding manner with between assembly.Have structure simple, easy to operate, install registration, good sealing effect, be more suitable for few dismounting or not demolition and high pressure-temperature large-size workpiece connection sealing.
