Abstract
The utility model provides hydrogenated nitrile-butadiene valve rubber of a mud pump. The hydrogenated nitrile-butadiene valve rubber of the mud pump comprises a valve body and a conical ring surface. The conical ring surface is arranged on the lower surface of the valve body, an elastic support sheet is solidified inside the valve body, is positioned on the inner side of the conical ring surface and is a thin-walled ring with an arc-shaped section, and the protruded direction of the arc-shaped section of the elastic support sheet faces the conical ring surface. The hydrogenated nitrile-butadiene valve rubber has the advantages that the arc-shaped support sheet which is made of elastic materials is solidified in the valve rubber and faces the conical ring surface with a sealing effect, so that the elastic strength of a valve can be greatly improved; the hydrogenated nitrile-butadiene valve rubber has characteristics of abrasion resistance and high-temperature resistance of hydrogenated nitrile-butadiene materials and has characteristics of elasticity and toughness of elastic steel, and accordingly the sealing performance of the valve can be improved; the abrasion loss is 0.2CC, accordingly, the hydrogenated nitrile-butadiene valve rubber is abrasion-resistant and is favorable for popularization and utilization, and the service life of the hydrogenated nitrile-butadiene valve rubber can be prolonged.
Description
Technical field
The utility model relates to petroleum production engineering seal member field, is specifically related to the fine slush pump valve of hydrogenation fourth rubber.
Background technology
Along with drilling technology, the particularly development of the new technology such as high-pressure jet drilling, near-balance drilling, clump formula directional well, horizontal well, new technology, slush pump also faces more and more higher pressure, vibration, its condition of work is very severe again simultaneously, operating mode is complex also, to slush pump valve reliability and safety more and more higher requirement is proposed, the first cause losing efficacy is abrasion resistance and the sensitivity to temperature difference of current common valve, mounting condition is poor again, therefore comparatively responsive to improve the shock and vibration causing because of jig frequency; Life-span of consumable accessory is short and easily lost efficacy and cause security incident suddenly.
Summary of the invention
In order to overcome the deficiency of background technology, the utility model provides the fine slush pump valve of hydrogenation fourth rubber to address the above problem.
The technical solution of the utility model is: the fine slush pump valve of hydrogenation fourth rubber, comprise the taper anchor ring below valve body and valve body, and in valve body interior, the inboard of taper anchor ring, is solidified with elastic support sheet.Elastic support sheet is that a cross section is the thin-walled ring of arc.
The cross section of described elastic support sheet is arc, its arc bloat direction towards taper anchor ring.
The utlity model has following beneficial effect: by adopting the arc support chip that elastomeric material is made to be solidificated in valve rubber intracutaneous, towards the taper anchor ring sealing, strengthened greatly the elastic strength of valve, have the Wear-resistant, high-temperature resistant of the fine material of hydrogenation fourth concurrently, simultaneously elasticity and the toughness of flexible steel, improved the sealing performance of valve, and abrasion loss is 0.2CC, there is wear-resisting characteristic, extended application life, favourable promoting the use of.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
1-valve body in figure, 2-taper anchor ring, 3-elastic support sheet.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the fine slush pump valve of hydrogenation fourth rubber, comprises valve body 1 and valve body 1 taper anchor ring 2 below, and in valve body 1 inside, the inboard of taper anchor ring 2, is solidified with elastic support sheet 3.
Described elastic support sheet 3 is that a cross section is the thin-walled ring of arc.
The cross section of described elastic support sheet 3 is arc, its arc bloat direction towards taper anchor ring 2.
By adopting the arc support chip that elastomeric material is made to be solidificated in valve rubber intracutaneous, towards the taper anchor ring sealing, strengthened greatly the elastic strength of valve, have the Wear-resistant, high-temperature resistant of the fine material of hydrogenation fourth concurrently, elasticity and the toughness of flexible steel of while, the sealing performance that has improved valve, increases the service life, favourable promoting the use of.
Because this utility model has adopted hydrogenation nitrile rubber as main encapsulant, more than thering is high pressure resistant 30MPa, the feature of high temperature resistant 180 ° of above oil resistants, and abrasion loss is 0.2CC, have wear-resisting characteristic, this product improves more than 10 times than common nitrile rubber application life.
