Abstract
The utility model provides a kind of combined drilling slurry pump valve bonnet seal circle, solves the problem that Sealing easily lost efficacy in high pressure, vibration, impact.This combined drilling slurry pump valve bonnet seal circle comprises body, body is made up of hydrogenation butadiene acrylonitrile rubber circle and the Steel Skeleton be wrapped in hydrogenation butadiene acrylonitrile rubber circle, described hydrogenation butadiene acrylonitrile rubber circle and the cross section of Steel Skeleton are rectangular configuration, the cross section of described hydrogenation butadiene acrylonitrile rubber circle is rectangular configuration, and its inner side surface is a recessed arc shaped surface.This combined drilling slurry pump valve bonnet seal circle is by the basis of general bowl RunddichtringO, in cushion rubber, Steel Skeleton is set, the consistency and elasticity of Steel Skeleton is utilized to compensate the deformation extent of cushion rubber when high pressure, vibration, improve sealing, and ensure under specific condition, ensure safety in production, and abrasion loss is 0.2CC, there is wear-resisting characteristic, favourablely to promote the use of.
Description
Technical field
The utility model relates to petroleum production engineering sealed member field, is specifically related to a kind of combined drilling slurry pump valve bonnet seal circle.
Background technique
Along with drilling technology, particularly high-pressure jet drilling, near-balance drilling, clump formula directional well, the new procesies such as horizontal well, the development of new technology, drilling mud pump is further to high-power, huge discharge and high pump pressure direction advance, as the drilling mud pump of rig " heart ", there are direct relation in its performance level and working life with bit speed and cost of production, its operating conditions is very severe again simultaneously, operating mode is complex also, more and more higher requirement is proposed to the reliability of drilling mud pump and Security, the first cause of the seal fails of drilling mud pump valve gap is that drilling mud pump power and discharge capacity are very large, installation conditions is poor again, therefore improve to because of jig frequency the impact caused, vibration is comparatively responsive, the life-span of easily damaged parts is short and easy inefficacy suddenly causes security incident.
Summary of the invention
In order to overcome the deficiency of background technique, the utility model provides a kind of combined drilling slurry pump valve bonnet seal circle to solve the problem.
The technical solution of the utility model is: this combined drilling slurry pump valve bonnet seal circle comprises body, and body is made up of hydrogenation butadiene acrylonitrile rubber circle and the Steel Skeleton be wrapped in hydrogenation butadiene acrylonitrile rubber circle.The cross section of hydrogenation butadiene acrylonitrile rubber circle and Steel Skeleton is rectangular configuration.
The cross section of described hydrogenation butadiene acrylonitrile rubber circle is rectangular configuration, and its inner side surface is a recessed arc shaped surface.
The utility model has following beneficial effect: this combined drilling slurry pump valve bonnet seal circle is by the basis of general bowl RunddichtringO, in cushion rubber, Steel Skeleton is set, the consistency and elasticity of Steel Skeleton is utilized to compensate the deformation extent of cushion rubber when high pressure, vibration, improve sealing, and ensure under specific condition, ensure safety in production, and abrasion loss is 0.2CC, there is wear-resisting characteristic, favourablely to promote the use of.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
1-body in figure, 2-Steel Skeleton, 3-arc shaped surface, 4-hydrogenation butadiene acrylonitrile rubber circle.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this combined drilling slurry pump valve bonnet seal circle, comprises body 1, and body 1 is made up of hydrogenation butadiene acrylonitrile rubber circle 4 and the Steel Skeleton 2 be wrapped in hydrogenation butadiene acrylonitrile rubber circle 4, and wherein, the cross section of hydrogenation butadiene acrylonitrile rubber circle 4 and Steel Skeleton 2 is rectangular configuration.
Described hydrogenation butadiene acrylonitrile rubber circle 4, its inner side surface is a recessed arc shaped surface 3.
Common valve gap seal ring at high pressure and vibration and under impacting all very strong condition working life short and easily lost efficacy, its reason is, the discontinuity of seal ring, pressure, vibration.Impact directly acts on inside the annulus of seal ring, so, this programme arranges Steel Skeleton 2 in conventional seals circle, Steel Skeleton 2 ensures that seal body part can not because of high pressure, vibration, plastic deformation is produced under the condition of impacting, simultaneously, the resiliently deformable of hermetic unit is unaffected, stressed from inner side surface (as shown in chain line two in figure) due to seal ring, pressure is on whole of inner side surface, distance edge section rigidity is better, intermediate portion rigidity is not enough, elasticity is had a surplus, so this face is designed to arc 3, under the Steel Skeleton 2 of liner acts on, arc 3 makes whole stress surface uniform elastic, time can give full play to sealing effect, ensure the deformation extent of cushion rubber in allowed limits, improve sealability.
Skeleton combined drilling slurry pump valve bonnet seal circle is by the basis of common bowl ring, the consistency and elasticity of Steel Skeleton 2 is utilized to compensate the deformation extent of cushion rubber when high pressure, vibration, improve sealing, and it is breakdown under extreme conditions to avoid whole cushion rubber to be not easy, ensure safety in production, favourablely to promote the use of.
Because this model utility have employed hydrogenation nitrile rubber as primary sealing material, there is high pressure resistant more than 30MPa, the feature of high temperature resistant more than 180 ° oil resistants, can normally work at drilling at the sea, land probing 1500-5000 rice well depth, and abrasion loss is 0.2CC, have wear-resisting characteristic, especially this product of oil-base mud improves more than 10 times than common nitrile rubber working life.
