Abstract
The utility model discloses a kind of oil pipe control valve sealing configuration for petroleum production building site, comprise oblique needle bearing, interior transition seal washer, sealed cover, valve shaft seal ring, valve body and valve shaft, described valve body is set on described valve shaft by described oblique needle bearing, described sealed cover is fixedly connected with on described valve shaft and with described valve body by described valve shaft ring set, and described interior transition seal washer is arranged between described sealed cover and described oblique needle bearing.Compared with prior art, the utility model adopts the joint of multi-sealed connection set sealing valve shaft and valve body, thereby guarantees in pipeline oil-proof, but also the working life that can improve control valve, reduce maintenance maintenance, save cost, there is the value of applying.
Description
Technical field
The utility model relates to a kind of petroleum production stand-by plant, relates in particular to a kind of oil pipe control valve sealing configuration for petroleum production building site.
Background technique
Oil claims again crude oil, be a kind of thickness, dark brown liquid.There is petroleum storage upper crustal some areas.Main component is the mixture of various alkane, cycloalkane, aromatic hydrocarbon.The one-tenth oil machine reason of oil has biogenic deposit to become oil and two kinds of theories of petrochemical industry oil, and the former more widely accepts, think oil be ancient times ocean or lake in the very long evolution formation of biology process, belong to fossil fuel, non-renewable; The latter thinks that oil is to be generated by the carbon of itself in the earth's crust, irrelevant, renewable with biology.Oil is mainly used as fuel oil and gasoline, is also that many chemical industry products are as the raw material of solution, chemical fertilizer, pesticide and plastics etc.Yet oil, in the process of exploitation, just needs the transportation of pipeline to oil, on pipeline, just need some control valves, valve of the prior art does not all have this special use, therefore, existing valve easily spills liquid from the place of valve shaft mostly, uses inconvenience, is difficult to promote.
Model utility content
The purpose of this utility model provides a kind of oil pipe control valve sealing configuration for petroleum production building site with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises oblique needle bearing, interior transition seal washer, sealed cover, valve shaft seal ring, valve body and valve shaft, described valve body is set on described valve shaft by described oblique needle bearing, described sealed cover is fixedly connected with on described valve shaft and with described valve body by described valve shaft ring set, and described interior transition seal washer is arranged between described sealed cover and described oblique needle bearing.
Further, between described sealed cover and described valve body, by fixing bolt, be fixedly connected with outer transition seal washer, the end of described valve shaft is provided with fixing pin and valve shaft dog point.
The beneficial effects of the utility model are:
The utility model is a kind of oil pipe control valve sealing configuration for petroleum production building site, compared with prior art, the utility model adopts the joint of multi-sealed connection set sealing valve shaft and valve body, thereby oil-proof in assurance pipeline, but also the working life that can improve control valve, reduce maintenance maintenance, save cost, there is the value of applying.
Accompanying drawing explanation
