A kind of anti-theft oil well exempts from emptying sampling valve, comprising: drain pipe (1), housing (2), spool (3), sealing shroud (4), dog screw (5), valve seat (6), copper sheathing (7).It is characterized in that: the housing (2) that described anti-theft oil well exempts from emptying sampling valve is cylindrical shape, through hole right-hand member undergauge is provided with internal thread, be connected with spool (3) external screw thread, left end is provided with external screw thread and is connected with valve seat (6) internal thread, fixed by dog screw (5), housing left end bottom is provided with oblique liquid outlet (0), and liquid outlet (0) is provided with oblique drain pipe (1).The utility model is applicable to the moisture laboratory sampling of oil well crude oil, easy to operate, opens valve and directly enrolls oil sample, and admission data is accurate, avoids oil, gas to lose and environment pollution, alleviates post labor strength, and have anti-theft feature, effectively prevent crude oil stolen.
Description
Technical field
The utility model relates to oilfield Wellhead crue oil sampler, and specifically a kind of anti-theft oil well exempts from emptying sampling valve.
Background technology
Oil well crude oil moisture chemical examination data is the daily production management of oil well and the necessary capsule information of underground dynamic analysis, and thus crude oil sampling is one of oil recovery work routine work every day.The dead oil remained in short circuit must be bled off before sampling, to ensure the accuracy of admission data, usually a pollutant discharge tube is put at well head, so also affect well site attractive in appearance, still cause certain oil, gas to lose, there is problem of environmental pollution, and add the labour intensity of post workman, and common sample cock is non-anti-theft, there is the stolen problem of crude oil.A kind of oil well exempts from emptying sampling valve, the patent No.: ZL201220465766.3, complex structure, and manufacturing cost is high, installs difficulty, and without anti-theft feature; A kind of sampling valve for oil pipeline, the patent No.: ZL201320544531.8, forward end seal poor performance, flowline area of passage is little, flowline level, has a small amount of dead oil, affects the accuracy of moisture analysis data, same without anti-theft feature.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of anti-theft oil well and exempts from emptying sampling valve.
The utility model is realized by following technical proposals:
Anti-theft oil well exempts from emptying sampling valve, comprising: drain pipe, housing, spool, sealing shroud, dog screw, valve seat, copper sheathing. the housing that described anti-theft oil well exempts from emptying sampling valve is cylindrical shape, through hole right-hand member undergauge is provided with internal thread, be connected with spool external screw thread, left end is provided with external screw thread and is connected with valve seat internal thread, fixed by dog screw, housing left end bottom is provided with oblique liquid outlet, and liquid outlet is provided with oblique drain pipe.
The port that above-mentioned anti-theft oil well exempts from the drain pipe in emptying sampling valve is elbow structure.
The above-mentioned anti-theft oil well spool of exempting from emptying sampling valve is six grades of multidiameter structures, and the first order is provided with frustum of a cone copper sheathing from left to right, and the third level is equipped with sealing shroud, and level V is provided with external screw thread, and the 6th grade is switch terminals.
The valve seat left end outside that above-mentioned anti-theft oil well is exempted from emptying sampling valve is provided with annular boss, and inside is provided with internal thread, and right-hand member outside is provided with the frustum of a cone, and inside is provided with tapered hole.
The beneficial effects of the utility model are: be applicable to the moisture laboratory sampling of oil well crude oil, easy to operate, open valve and directly enroll oil sample, admission data is accurate, avoids oil, gas to lose and environment pollution, alleviates post labor strength, and there is anti-theft feature, effectively prevent crude oil stolen.
