Abstract
The utility model relates to a sampling valve at the oil extraction well mouth, comprising a valve housing which is connected to the well mouth oil pipe. The thread is arranged on the outside of the valve housing for connection with the well mouth oil pipe. The axial sampling oil channel is arranged on the inner valve shell. The oil inlet of the oil channel is a tapered bell mouth. The valve spindle is arranged on the oil channel, the front end of the valve spindle is arranged with a plugging head which corresponds to the oil channel inlet tapered bell mouth. Another end of the valve spindle is connected to the thread on the valve housing, the diameter of one section of valve spindle between the junction point and the plugging head are smaller than that of the sampling oil channel. The valve spindle out of the valve housing is arranged with a handle, a bypass oil outlet channel is arranged on the oil sampling channel. Compared to the existed technology, there is no residual dead oil in the oil extraction sampling oil channel, there is no dead oil freezing during sampling in winter. The operation is convenient.
Description
Technical field
The utility model relates to a kind of production wellhead sample valve.
Background technology
At present, existing production wellhead sample valve, comprise fuel-displaced elbow mouth, valve, nipple and plug, valve and well head oil pipe tie point have a segment pipe, always have dead oil after each sampling in this pipeline, when sub-sampling down, need drain the dead oil in this segment pipe earlier, could take a sample Deng after the green oil outflow, also can often freeze in the winter time, cause the sampling mouth to stop up because of this ducted dead oil.
Technology contents
The purpose of this utility model is to provide a kind of no dead oil to exist, in the winter time the production wellhead sample valve of taking a sample and can not stop up.
The utility model comprises a valve casing that can be connected with the well head oil pipe, valve casing is provided with the screw thread that can be connected with the well head oil pipe outward, be provided with axial sampling oil duct in the valve casing, this oil duct oil-in is the horn mouth that is the vertebra shape, be provided with valve core rod in the oil duct, the valve core rod front end has and the corresponding plug of oil duct oil-in vertebra shape horn mouth, the valve core rod other end is threaded with valve chest and one section valve core rod diameter of plug is arrived less than sampling oil duct diameter in the junction, on the valve core rod outside the valve chest handle is arranged, be provided with the bypass oil discharge passage at sampling oil duct middle part.
Above-mentioned bypass oil discharge passage is preferably two, is being in relatively on the valve casing on the same diameter line, and both sides pass-out oil passage is equipped with internal thread, on one of them bypass oil discharge passage plug is arranged, and preferably is provided with the sampling oil outlet on another bypass oil discharge passage.
During use valve chest of the present utility model is connected on the oil country tubular good, the valve core rod plug stretches in the oil-piping and gets final product, and rotating valve core bar handle can promote the valve core rod plug, makes the sampling oil duct be in the state of opening or closing.If establish two bypass oil discharge passages on same diameter line relative on the valve casing, one of them passage is blocked in the position of bypass oil discharge passage in the time of then being connected with oil country tubular good according to valve casing easily, keeps a passage.
Compared with prior art, the utility model recovers the oil, and the noresidue dead oil exists in the sampling oil duct, and sampling does not have dead oil yet and freezes easy for operation in the winter time.
Description of drawings
Fig. 1 is the structural representation of enforcement 1 of the present utility model.
Fig. 2 is the structural representation of enforcement 2.
1 is valve casing among the figure, and 2 is handle, and 3 is bypass oil discharge passage plug, and 4 is valve core rod, and 5 is the valve core rod plug, and 6 are the sampling oil outlet.
The specific embodiment
Embodiment 1:
The utility model comprises valve casing, valve casing is provided with the screw thread that can be connected with the well head oil pipe outward, be provided with axial sampling oil duct in the valve casing, this oil duct oil-in is the horn mouth that is the vertebra shape, be provided with valve core rod in the oil duct, the valve core rod front end has and the corresponding plug of oil duct oil-in vertebra shape horn mouth, the valve core rod other end is threaded with valve chest and one section valve core rod diameter of plug is arrived less than sampling oil duct diameter in the junction, on the valve core rod outside the valve chest handle is arranged, be provided with the bypass oil discharge passage at sampling oil duct middle part, the bypass oil discharge passage is two, be in relatively on the valve casing on the same diameter line, both sides pass-out oil passage is equipped with internal thread, on one of them bypass oil discharge passage plug is arranged, another bypass oil discharge passage is provided with the sampling oil outlet, can as required above-mentioned plug and sampling oil outlet be exchanged, and guarantees that oil outlet is all the time below valve.
Embodiment 2:
Difference from Example 1 has been to prolong the valve casing by valve core rod plug one end, and the valve casing external diameter that prolongs is smaller, and this fuel tap is applicable to the thin oil sampling.
Claims (3)
1, a kind of production wellhead sample valve, comprise a valve casing that can be connected with the well head oil pipe, valve casing is provided with the screw thread that can be connected with the well head oil pipe outward, it is characterized in that being provided with in the valve casing axial sampling oil duct, this oil duct oil-in is the horn mouth that is the vertebra shape, be provided with valve core rod in the oil duct, the valve core rod front end has and the corresponding plug of oil duct oil-in vertebra shape horn mouth, the valve core rod other end is threaded with valve chest and one section valve core rod diameter of plug is arrived less than sampling oil duct diameter in the junction, on the valve core rod outside the valve chest handle is arranged, be provided with the bypass oil discharge passage at sampling oil duct middle part.
2, production wellhead sample valve as claimed in claim 1, it is characterized in that described bypass oil discharge passage is preferably two, be in relatively on the valve casing on the same diameter line that both sides pass-out oil passage is equipped with internal thread, on one of them bypass oil discharge passage plug is arranged
