Abstract
The invention discloses a sealing ring used for a petroleum machinery, comprising a ring body, wherein the ring body is made of alloy steel; an upper portion of the ring body is provided with a sleeve; a lower portion of the ring body is provided with a circular ring; the sleeve is provided with circular holes; the circular holes are arranged uniformly; and a groove is arranged on the bottom of the circular ring. The sealing ring has simple technology and smart design; the sealing ring can be used for the petroleum machinery conveniently; the sealing ring has good sealing property; and the sealing ring is made of alloy steel, so that overall performance is improved, and service life is prolonged; the technology and the manufacturing method are more conveniently; structure is simple; appearance is elegant; range of application is wide; production cost can be saved; design is novel; and the sealing ring is a new design proposal, and is suitable for being popularized and used.
Description
Technical field
The present invention relates to the petroleum processing field, particularly relate to the seal ring that a kind of petroleum machinery uses.
Background technique
Seal ring is the main Sealing of swivel joint, bears pressure medium and running shaft (outer tube), housing friction during operation, the working life of factor appreciable impact seal rings such as temperature, rotating speed and medium.Be that its end face is fitted and two ring-shaped work piecess of slide relative perpendicular to spin axis each other in the mechanical seal.Patent application document such as Chinese application number 201180003565.X discloses a kind of seal ring, its effect of torque that can more stably be reduced.Annular gap between the axle of axle sleeve that the sealing of sealing ring can rotate freely relatively and the axis hole that inserts this axle sleeve; Can be installed in the annular slot that is arranged at the axle surface, utilize the pressure of sealed object fluid, be pressed on the side of annular slot and the inner peripheral surface surface of axis hole respectively; With the sliding area of the side slip of annular slot; The recess that formation separates with the side of annular slot in the effect of pressure, produces opposing it is pressed in the power of active force of the side of annular slot; Recess has circular-arc its inboard along said sliding area and extends at circumferencial direction; Importing portion, it imports to this circular-arc portion from extending with the end of end upper reaches one side of sealed object fluid flow direction to said circular-arc of the said sliding area of sealed object zone adjacency with the sealed object fluid.But the using scope of this seal ring is limited, can not be applied in the special environment, and manufacture the technology more complicated, and the flexibility ratio of use is not strong, and the cost that uses is than higher, so be unfavorable for promoting the use of.
In sum, to the defective of existing technology, the seal ring that needs a kind of petroleum machinery to use especially, thereby the problem of mentioning more than solving.
Summary of the invention
The technical problem that the present invention mainly solves provides the seal ring that a kind of petroleum machinery uses, and the sealing that can solve traditional seal ring is not good, and makes than problems such as more complicateds.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the seal ring that provides a kind of petroleum machinery to use comprises ring body; Described ring body adopts alloyed steel to be made; The top of ring body is provided with external member, and its underpart is provided with annulus, offers above the described external member and is equipped with circular hole; Arrange evenly between described circular hole and the circular hole, the bottom of described annulus is provided with groove.
In preferred embodiment of the present invention, the shape of described ring body is tapered.
In preferred embodiment of the present invention, the diameter of described ring body is 300mm.
The invention has the beneficial effects as follows: technology of the present invention is simple, designs ingeniously, can be convenient to use on petroleum machinery, and good sealability is arranged; And adopt alloyed steel to be made again, and make whole performance all get lifting, increased the life-span of using, technology and making method are all more convenient; Simple in structure, profile is exquisite, and the scope of use is wide, has saved production cost; Modern design is a kind of new design proposal, and profit is promoted the use of.
Description of drawings
Fig. 1 is the structural representation of the seal ring of a kind of petroleum machinery use of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Seal ring as shown in Figure 1, that a kind of petroleum machinery of the present invention uses comprises ring body 100; Described ring body 100 adopts alloyed steel to be made; The top of ring body 100 is provided with external member 120, and its underpart is provided with annulus 110, offers above the described external member 120 and is equipped with circular hole 130; Arrange evenly between described circular hole 130 and the circular hole 130, the bottom of described annulus 110 is provided with groove 140.
In preferred embodiment of the present invention, the shape of described ring body 100 is tapered.
In preferred embodiment of the present invention, the diameter of described ring body 100 is 300mm.Technology is simple, designs ingeniously, can be convenient to use on petroleum machinery, and good sealability is arranged; And adopt alloyed steel to be made again, and make whole performance all get lifting, increased the life-span of using, technology and making method are all more convenient; Simple in structure, profile is exquisite, and the scope of use is wide, has saved production cost; Modern design is a kind of new design proposal, and profit is promoted the use of.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
