Abstract
The utility model relate to an oil extraction shaft mouth antifreezing sampling device which is formed by a valve body 10, a fixing base 14, a valve seat 13, a seal ring 11, a seal box 6, a valve rod 2, a press cap 3, a press ring 4, seal materials 5 and a hand wheel 1. Two ends of the valve body 10 are provided with connecting threads 9 which can be connected to an oil conveying pipeline of a shaft mouth. The oil extraction shaft mouth antifreezing sampling device can fully utilize hot oil in the oil conveying pipeline of the oil extraction shaft mouth, guarantees non-freezing and non-bonding of the valve rod 2 and the valve seat 13, can also be normally used in winter in an alpine region, avoids sampling troubles and unsafe factors caused by freezing, and brings great convenience to daily sampling operation. The oil extraction shaft mouth antifreezing sampling device can significantly improve work efficiency, reduces production cost, lightens labor intensity, and increases economic benefits of oil extraction production.
Description
Technical field
The utility model relates to a kind of anti-freezing sampling device of oil extraction in oil field well head.
Background technology
The oil extraction in oil field producing well assay that will regularly draw oil sample generally is to take laterally to pick out on the well head petroleum pipeline short circuit that is communicated with, and the front connects the sampling cock again.But these all can not adapt to the low temperature environment in winter, immobilising fluid is usually frozen and blocking pipeline causes and can't take a sample at ordinary times in short circuit and the sampling cock, need to adopt the ways such as hot water scalds, baked wheaten cake to solve, dredging a bite well often needs for a long time, and the well number is numerous, and operation is wasted time and energy, and the staff works in low temperature and strong wind atmosphere for a long time simultaneously, very easily cause personnel's frostbite, bring very large trouble and cause easily unsafe factor to work.
Summary of the invention
The purpose of this utility model is to provide a kind of production wellhead anti-freezing sampling device that also can normally use in the winter of extremely frigid zones, avoids freezing to cause trouble and causing unsafe factor because of sampling line.
For achieving the above object, the utility model is comprised of valve body, firm banking, valve seat, sealing ring, seal box, valve rod, pressure cap, pressure ring, sealing material, handwheel.Wherein there is connecting thread at the valve body two ends, and seal box is arranged at valve body top, and firm banking is arranged at the bottom.Sealing material and pressure ring are positioned at seal box inside, and are enclosed within on the valve rod, and pressure cap is threaded connection in the seal box upper end.Maximum gauge place, valve rod middle part is screw thread, can cooperate with the internal whorl on the seal box.There is cone the valve rod lower end, and the upper end is fixed with handwheel.Valve seat is connected on the firm banking of valve body, and the valve seat upper end is positioned at the middle part of valve body, and there is through hole at the center, and the center line of valve seat and the center line of the valve rod in the seal box are located along the same line, and between valve seat and the firm banking sealing ring are arranged.
The connecting thread at valve body two ends can be internal thread, also can be external screw thread, can also be an end internal thread one end external screw thread.
Adopted after the said structure, hand wheel rotating moves downward valve rod by screw thread, and the cone of valve rod lower end stretches in the through hole at valve seat center, seals up through hole, can carry out daily production.Surround because cone and valve seat are arranged in petroleum pipeline deep fat liquid, therefore can not freeze sticking dead.During sampling, because the through hole at valve seat center is vertical, sample fluid has also avoided raffinate to freeze to stop up without delay under action of gravitation.
Description of drawings
Accompanying drawing is the sectional view of a kind of specific embodiment of the utility model production wellhead anti-freezing sampling device.
The specific embodiment
As shown in drawings, the utility model is comprised of valve body 10, firm banking 14, valve seat 13, sealing ring 11, seal box 6, valve rod 2, pressure cap 3, pressure ring 4, sealing material 5, handwheel 1.Wherein there is connecting thread 9 at valve body 10 two ends, and seal box 6 is arranged at valve body 10 tops, and firm banking 14 is arranged at the bottom.Sealing material 5 and pressure ring 4 are positioned at seal box 6 inside, and are enclosed within on the valve rod 2, and pressure cap 3 is threaded connection in seal box 6 upper ends.Maximum gauge place, valve rod 2 middle part is screw thread, can cooperate with the internal whorl on the seal box 6.There is cone 8 valve rod 2 lower ends, and the upper end is fixed with handwheel 1.Valve seat 13 is connected on the firm banking 14 of valve body 10, valve seat 13 upper ends are positioned at the middle part of valve body 10, there is through hole 12 at the center, and the center line of the valve rod 2 in the center line of valve seat 13 and the seal box 6 is located along the same line, and between valve seat 13 and the firm banking 14 sealing ring 11 is arranged.
In daily production, handwheel 1 rotates, and by screw thread valve rod 2 is moved downward, and the cone 8 of valve rod 2 lower ends stretches in the through hole 12 at valve seat 13 centers, seals up through hole 12, prevents the fluid outflow in the petroleum pipeline, guarantees to produce normally.Surround because cone 8 and valve seat 13 are arranged in the valve body 10 inner deep fat liquid that constantly flow, how low therefore no matter manage outer temperature, and valve rod 2 and valve seat 13 can not freeze sticking dead.When needing sampling, reverse rotation handwheel 1, valve rod 2 upwards rises, the through hole 12 of valve seat 13 and the internal communication of valve body 10, the fluid in the petroleum pipeline can flow out by through hole 12, finishes sample collection work.Because the through hole 12 at valve seat 13 centers is vertical, sample fluid has also been avoided raffinate to freeze through hole 12 and has been resulted in blockage without delay under action of gravitation.
In order to adapt to on-the-spot needs; the connecting thread 9 at valve body 10 two ends; it can be internal thread; it also can be external screw thread; it can also be an end internal thread one end external screw thread; even valve body 10 can also be directly to be welded on the petroleum pipeline, and such conversion is all within protection domain of the present utility model.
