Abstract
The utility model relates to an anti-theft sampling valve which is an anti-theft device for an oil production wellhead; the upper end of an oil inlet pipe is provided with a thread, and the lower end of the oil inlet pipe is welded on the upper end of an outer shell; the upper end of an oil outlet pipe is welded on the lower end of the outer shell, and the lower end of the oil outlet pipe is provided with a flange; the insides of the oil inlet pipe, the outer shell and the oil outlet pipe are communicated; an anti-theft valve is arranged in the outer shell; the anti-theft valve is welded on the outer shell; the left end of the anti-theft valve extends out of the outer shell, the front end of the anti-theft valve is provided with a sample inlet, and the rear end of the anti-theft valve is connected with a sampling tube; after being bent, the sampling tube extends out of the outer shell; the sampling tube and the outer shell are welded together; the outer end of the sampling tube is provided with a male thread; a password box is welded on the outer shell, and covers the anti-theft valve; a password plate is arranged on the password box; the password plate is hung on a shoulder in the password box; after a password is obtained, the password plate is separated from the password box by rotating a lock cylinder on the password plate; then an anti-theft key is used for opening the anti-theft valve, so that the sample inlet is communicated with the sampling tube, an oil sample in the outer shell can flow out of the sampling tube and is taken out, and a thief cannot steal crude oil from a sampling port of an oil well.
Description
Technical field
The utility model is a kind of anti-theft device of oil well mouth usefulness, is a kind of anti-theft sampling valve.
Background technology
In oil well production, need sampling place on the ground well head of oil well or the conveyance conduit, be used to take oil sample, so that the various compositions in the chemical examination oil well produced liquid.Sampling place is generally by a common valve control.At the scene, thief is easy to open valve from sampling and steals crude oil, causes substantial oil stolen, causes serious economy loss to the oil field.
Summary of the invention
The purpose of this utility model is a kind of anti-theft sampling valve of design, makes thief can not open the valve stolen, avoids crude oil stolen, reduces the oilfield economic loss.
The purpose of this utility model is achieved in that and comprises oil inlet pipe, password box, combination disk, antitheft valve, probe tube, shell, flowline, flange, there is screw thread the oil inlet pipe upper end, the oil inlet pipe lower end is welded on the shell upper end, the flowline upper end is welded on the shell lower end, there is flange the flowline lower end, oil inlet pipe, shell, flowline inside communicates, enclosure is installed antitheft valve, antitheft valve is welded on the shell, and antitheft valve left end stretches out shell, and antitheft valve front end has injection port, antitheft valve rear end connects probe tube, extend outside the shell after the probe tube bending, probe tube and shell weld together, and there is male thread the probe tube outer end, password box is welded on the shell, password box covers antitheft valve, and combination disk is installed on the password box, and combination disk hangs on the interior shoulder of password box.
The beneficial effects of the utility model are: combination disk hangs on the interior shoulder of password box, after obtaining password, combination disk is separated with password box by the lock on the rotation combination disk, and then open antitheft valve with anti-theft key, injection port is communicated with probe tube, oil sample in the shell could flow out removed from probe tube, thief can't obtain password, can't reach the purpose of stolen.Owing in the shell antitheft valve has been installed also,, thief also can't steal crude oil again even having destroyed combination disk.So thief can't be from oil well sampling theft crude oil.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 embodiment of the present utility model is described.
As shown in Figure 1, embodiment of the present utility model comprises oil inlet pipe 1, password box 2, combination disk 3, antitheft valve 4, probe tube 5, shell 6, flowline 7, flange 8, there is screw thread oil inlet pipe 1 upper end, so that be connected with wellhead assembly, oil inlet pipe 1 lower end is welded on shell 6 upper ends, flowline 7 upper ends are welded on shell 6 lower ends, there is flange 8 flowline 7 lower ends, flowline 7 is welding with flange 8, flange 8 is connected with back pressure valve on the flow line, oil inlet pipe 1, shell 6, flowline 7 inside communicate, the antitheft valve 4 of shell 6 inner installations, antitheft valve 4 is welded on the shell 6, reach seal request, antitheft valve 4 left ends stretch out shell 6, and antitheft valve 4 front ends have injection port 9, and antitheft valve 4 rear ends connect probe tube 5, extend outside the shell 6 after probe tube 5 bendings, probe tube 5 welds together with shell 6, reaches seal request, and there is male thread probe tube 5 outer ends, can connect by sample cock, password box 2 is welded on the shell 6, and password box 2 is coaxial with antitheft valve 4, and password box 2 covers antitheft valve 4, combination disk 3 is installed on the password box 2, combination disk 3 hangs on the password box 2 interior shoulders, makes combination disk 3 block antitheft valve 4, plays antitheft effect.
During oil well production, the well liquid of extraction is through oil inlet pipe 1, shell 6, flowline 7 flows out, during sampling, at first to rotate lock on the combination disk 3 with special tool, have six locks on the combination disk 3, do not hang on the password box 2 after making the lock dog rotation on lock right side, the direction of rotation of lock and angle are password, have only the operative employee talent to know, therefore, thief can not have been got combination disk, after the operator takes off combination disk, open antitheft valve 4 with anti-theft key again, the injection port 9 on the antitheft valve 4 is communicated with probe tube 5, the liquid stream in the housing 6 flows out removed from probe tube 5.
