Description
Technical field
The utility model relates to a kind of petroleum machinery parts, particularly a kind of well mouth of oil well two-way oil return apparatus.
Background technology
In routine duties, oil wells in field is carried out oil well heat through original well liquid heat cycles device commonly used and is washed the work such as pipeline, oil wells in field mark product.When carrying out these work, all need the upper flange of back-pressure gate is dismantled, then loosen the resistance oil nozzle sleeve clamp hoop screw, on turn over vertical conduit, remove old mat, add new pad at import and export again, it is long that this operation trouble is stopped the well time, affected rate when driving a well, affected output, and winter also insulation to be pounded, caused unnecessary workload, increased workman's labour intensity.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of well mouth of oil well two-way oil return apparatus is provided, and easy to connect rapid, good sealing effect has reduced workman's labour intensity, has improved rate when driving a well, and has increased crude output.
Its technical scheme is to comprise that oil nozzle linkage, resistance oil nozzle sleeve linkage, sealing device, oil nozzle linkage outlet connection and resistance oil nozzle sleeve linkage inlet union form, one end of oil nozzle linkage is provided with the screw thread identical with oil nozzle, and the other end is provided with oil nozzle linkage outlet connection; One end of resistance oil nozzle sleeve linkage is provided with the screw thread identical with resistance oil nozzle sleeve, and the sidewall downside is provided with resistance oil nozzle sleeve linkage inlet union; The other end at the resistance oil nozzle sleeve linkage is provided with sealing device; The oil nozzle linkage is penetrated in the resistance oil nozzle sleeve linkage, add sealed packing in sealing device; The entrance of instrument is communicated with oil nozzle linkage outlet connection by high pressure line, and the outlet of instrument is communicated with resistance oil nozzle sleeve linkage inlet union by pipeline;
Produced Liquid enters in instrument through oil nozzle linkage outlet connection, then enters the annular space of oil nozzle linkage and resistance oil nozzle sleeve linkage through resistance oil nozzle sleeve linkage inlet union.
The sidewall of above-mentioned resistance oil nozzle sleeve linkage inlet union is provided with the emptying gate.
Right-hand member processing step Glan, gland and the pressure cap of above-mentioned sealing device.
The beneficial effects of the utility model are: this device is easy to connect rapidly, good sealing effect, when oil well needs heat to wash pipeline or mark product, the oil nozzle linkage is penetrated in the resistance oil nozzle sleeve linkage, add packing in sealing device, realize sealing, Produced Liquid enters various instruments through outlet like this, enter oil nozzle linkage and resistance oil nozzle sleeve linkage annular space through import again, then enter the well head two-way oil return flow process of production flow line; Need not again the upper flange of back-pressure gate be dismantled, loosen the resistance oil nozzle sleeve clamp hoop screw, on turn over vertical conduit, remove old mat, add the work of new pad, reduced unnecessary workload.
