Abstract
The utility model relates to an internal sealing valve seat ring of an oil field metering station multi-way valve. The valve seat ring is characterized in that the sealing work surface of the valve seat ring is provided with 1-2 small grooves, the sections of the grooves are V-shaped, U-shaped and small rectangle-shaped. The inner leakage rate of the multi-way valve upper valve body and the valve seat ring plane sealing is further reduced during the flow channel gating of the oil well multi-way valve improving the grade of inner sealing and enlarging the application scope of the multi-way valve in high oil & gas ratio oil wells and gas production oil wells.
Description
Affiliated technical field the utility model relates to the inner sealing seat ring structure of a kind of petroleum metering station multi-way valve, particularly when oil well multi-way valve runner gating, the internal leakage of multi-way valve upper valve body and seat ring plane sealing will further reduce, the seat ring that the sealing grade further improves.
Background technique
At present, existing seat ring working seal face does not have annular groove, and its sealed working face surfacing cemented carbide or ceramet are as patent ZL200420006528.1 and ZL200620167076.4.When multi-way valve runner gating, the multi-way valve upper valve body contacts with seat ring and forms the plane annular sealing strip, seat ring contact seal specific pressure is that the butterfly spring below seat ring provides, indoor clear water test pressure is 0.35～0.4MPa, seat ring internal leakage grade reaches GB/T4213-1992IV level level, can satisfy the requirement of conventional oil well and low oil-gas ratio well recovery metering.But require to reach VI level level for discharge in high oil-gas ratio oil well and the gas recovery well seat ring, existing multi-way valve seat valve ring seal leakage grade is difficult to reach the VI level, so can not meet the demands.
Summary of the invention
The purpose of this utility model is: high oil-gas ratio oil well and gas production oil well are higher to seat ring internal leakage class requirement, can not reach the shortcoming of VI level level at existing no annular groove seat ring internal leakage grade, the utility model has designed the circular groove type seat ring, increased slit seepage flow fluid resistance, improved interior sealing grade, enlarged the application area of multi-way valve at high oil-gas ratio oil well and gas production oil well.
The technical scheme in the invention for solving the technical problem is: open 1～2 road sulculus on existing seat ring sealed working face, the sulculus sectional shape is " V ", " U " and little rectangle, other parts are constant, when fluid passes through the outside seepage flow of plane gap in seat ring, increased the resistance link at the sulculus place, seepage discharge is reduced, thereby improved sealing effect.When indoor clear water test pressure was 0.35～0.4MPa, seat ring internal leakage grade reached VI level (GB/T4123-1992).
The beneficial effects of the utility model are: do not increase other costs, only need to open 1～2 road sulculus on original seat ring sealed working face, improved the sealing grade, enlarged the application area of multi-way valve at high oil-gas ratio oil well and gas production oil well.
Description of drawings
Accompanying drawing 1 is that the utility model master looks and partly cuts open figure.
Accompanying drawing 2 is the utility model plan view.
Embodiment
Below in conjunction with accompanying drawing and example the utility model is further specified.
Example one: on existing seat ring sealed working face, open 1～2 road sulculus, the sulculus sectional shape is " V ", " U " and little rectangle, other parts are constant, when fluid passes through the outside seepage flow of plane gap in seat ring, increased the resistance link at the sulculus place, reduce Leckage, thereby improved sealing effect.When indoor clear water test pressure was 0.35～0.4MPa, seat ring internal leakage grade reached VI level (GB/T4123-1992).
Claims (2)
1. a circular groove type seat ring is characterized in that opening 1～2 road sulculus on seat ring seal operation surface.
2. circular groove type seat ring according to claim 1 is characterized in that the sulculus sectional shape is " V ", " U " and little rectangle.
