Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

Referring to fig. 1 to 4, an embodiment of the present invention provides a seal ring for a petroleum machine, where the seal ring for the petroleum machine includes: sealing washer body 1 and solid fixed ring 2.

In the embodiment of the present invention, please refer to fig. 1 and fig. 3, the fixing ring 2 is disposed in the sealing ring body 1, and a plurality of evenly distributed bumps 2a are fixed on the top side and the bottom side of the fixing ring 2.

It should be noted that: when the sealing ring is used in the later period, when the connecting part extrudes the sealing ring body 1, the fixing ring 2 in the sealing ring body 1 can support and guide the external sealing ring body 1 to a certain extent, so that the sealing ring body 1 can expand along the vertical direction of extrusion force, and the phenomenon that the sealing ring body 1 is distorted and deformed due to the rotation of the connecting part in the installation process of the sealing ring body 1 can be reduced;

in the present embodiment, the fixing ring 2 is made of an elastic steel material, so that the fixing ring 2 can increase the supporting strength of the sealing ring body 1, and further reduce the deformation or fracture damage of the sealing ring body 1 to a certain extent.

In an embodiment of the present invention, please refer to fig. 1 and fig. 2, a first mounting groove 1a is formed inside the sealing ring body 1, and an inner wall of the first mounting groove 1a is fixedly connected to an outer wall of the fixing ring 2. A plurality of clamping grooves 1b are formed in the inner wall of the first mounting groove 1a, the clamping grooves 1b are uniformly distributed in the first mounting groove 1a in an annular manner, as shown in fig. 2, the positions of the clamping grooves 1b correspond to the positions of the lugs 2a, and the inner wall of each clamping groove 1b is attached to the outer wall of the corresponding lug 2a.

It should be noted that: through first mounting groove 1a, can make solid fixed ring 2 smooth install in sealing washer body 1, simultaneously through a plurality of lugs 2a and draw-in groove 1 b's joint laminating, can make solid fixed ring 2 more stable with being connected of sealing washer body 1, but the phenomenon of displacement appears in solid fixed ring 2 of greatly reduced in sealing washer body 1.

In the embodiment of the present invention, please refer to fig. 3, a second mounting groove 2b is disposed inside the fixing ring 2, the longitudinal section of the fixing ring 2 is flat, and the fixing ring 2 is also made of elastic steel.

It should be noted that: through establishing solid fixed ring 2 to the platykurtic, consequently the later stage when carrying out mechanical connection, when adapting unit extrudees sealing washer body 1, the solid fixed ring 2 of platykurtic structure is when receiving the extrusion force to deform, can be more even extrude the sealing washer body 1 of outer wall setting, can make the inflation of sealing washer more even.

In the embodiment of the present invention, please refer to fig. 4, a plurality of support rings 3 that are fixedly connected and distributed annularly are disposed inside the second mounting groove 2b, and each support ring 3 is also made of elastic steel.

It should be noted that: through fixing the inside a plurality of support rings 3 that set up of ring 2, in the use that carries out this sealing washer body 1, when dismantling the maintenance to mechanical part, when the junction of machinery removes the extrusion back to sealing washer body 1, the elasticity of the support ring 3 accessible self that elastic steel made increases the effect that solid fixed ring 2 kick-backs and reset, consequently also can make the more outstanding of reseing of sealing washer body 1.

The utility model provides a sealing washer that oil machinery used's theory of operation as follows:

through at 1 inside solid fixed ring 2 that sets up of sealing washer body, and gu be connected through a plurality of evenly distributed's fixture block between fixed ring 2 and the sealing washer body 1.

Therefore, in the later stage, when the sealing ring is used, after the worker sleeves the device at the connecting position of the pipeline, when the connecting part extrudes the sealing ring body 1, the fixing ring 2 in the sealing ring body 1 can support and guide the external sealing ring body 1 to a certain extent, so that the sealing ring body 1 can expand along the vertical direction of the extrusion force, and the phenomenon that the sealing ring body 1 is distorted and deformed due to the rotation of the connecting part in the installation process can be reduced.

And because solid fixed ring 2 adopts the elastic steel to make, therefore solid fixed ring 2 can increase the support intensity of sealing washer body 1, and then can reduce the phenomenon that fracture or deformation damage appear in sealing washer body 1 to a certain extent.

Simultaneously through the setting of the solid fixed ring of elasticity 2, when adapting unit is extrudeing sealing washer body 1, gu fixed ring 2 is when receiving the extrusion and warp, can extrude sealing washer body 1 from inside to outside, when the outer wall of sealing washer body 1 offsets with the connecting piece, through the solid fixed ring 2 of inside to the extruded cooperation of sealing washer body 1, can make the inseparabler of the inner wall laminating of sealing washer body 1 outer wall and connecting piece, consequently can increase the sealed effect of inflation of sealing washer body 1 on a certain journey.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention can be used in other related technical fields, either directly or indirectly, and the same principle is included in the protection scope of the present invention.
