Abstract
An adjustable oil well sampling pressure-measuring burglarproof valve comprises a lock sleeve, a burglarproof lock cylinder, a valve body, a left sealing seat, a spherical valve core, a right sealing seat and an oil discharging pipe. The spherical valve core is installed in a valve cavity of the valve body and connected with the burglarproof lock cylinder, the lock sleeve wraps the burglarproof lock cylinder, the lower portion of the lock sleeve is fixed on the valve body, the left sealing seat is positioned on the left side of the spherical valve core and is in spherical surface contact with the spherical valve core, the right sealing seat is positioned on the right side of the spherical valve core and is in spherical surface contact with the spherical valve core, the spherical valve core is provided with a horizontal through hole, and the oil discharging pipe is installed on one side of the valve body. An adjusting ring is connected into a screw hole positioned in the left end of the valve body through a thread and presses the left sealing seat, the horizontal through hole of the spherical valve core is not communicated with the left sealing seat and the right sealing seat after the spherical valve core rotates, the burglarproof lock cylinder is in a lockout state at the time, and the spherical valve core can only be opened with a key matched with the burglarproof lock cylinder, so that stealers cannot open the adjustable oil well sampling pressure-measuring burglarproof valve without the key and cannot achieve the purpose of stealing oil.
Description
Technical field
The utility model is the anti-theft device that a kind of oil extraction in oil field well head is used, and is a kind of adjustable oil well sampling pressure-measuring valve for guarding against theft.
Background technology
In oil well production, on the ground well head of oil well or conveyance conduit, need to have sampling place, for taking oil sample or measuring line pressure, sampling is in order to chemically examine the various compositions in oil well produced liquid, pressure measurement is the unimpeded situation of understanding flow line.Sampling pressure-measuring place is generally controlled by a common valve.At the scene, thief is easy to open valve from sampling and steals crude oil, causes substantial oil stolen, to oil field, causes serious economic loss.
Summary of the invention
The purpose of this utility model is a kind of adjustable oil well sampling pressure-measuring valve for guarding against theft of design, makes thief can not open valve stolen, avoids crude oil stolen, reduces oilfield economic loss.
The purpose of this utility model is achieved in that and comprises lock tube, anti-theft lock, valve body, left seal receptacle, spherical valve core, right seal receptacle, drain line, spherical valve core is arranged in the valve pocket of valve body, spherical valve core is connected with anti-theft lock, lock tube encases anti-theft lock, the bottom of lock tube is fixed on valve body, the left side of spherical valve core is left seal receptacle, left seal receptacle and spherical valve core are sphere-contact, the right side of spherical valve core is right seal receptacle, right seal receptacle and spherical valve core are sphere-contact, on spherical valve core, have cross through hole, drain line is arranged on a side of valve body.
Adjustable ring is threaded connection in the left end screw of valve body, and adjustable ring compresses left seal receptacle.
The beneficial effects of the utility model are: after spherical valve core rotation its cross through hole not with left seal receptacle ,You seal receptacle UNICOM, now anti-theft lock is in locking state, can only be with just opening rotary spherical spool with the supporting key of anti-theft lock, therefore, thief does not have key cannot open the utility model, cannot reach the object of stolen.
Accompanying drawing explanation
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises lock tube 1, anti-theft lock 2, valve body 3, adjustable ring 4, left seal receptacle 5, spherical valve core 6, right seal receptacle 8, drain line 9, spherical valve core 6 is arranged in the valve pocket of valve body 3, spherical valve core 6 is connected with anti-theft lock 2, lock tube 1 encases anti-theft lock 2, the bottom of lock tube 1 is fixed on valve body 3, the left side of spherical valve core 6 is left seal receptacles 5, left seal receptacle 5 is sphere-contact with spherical valve core 6, the right side of spherical valve core 6 is right seal receptacles 8, right seal receptacle 8 is sphere-contact with spherical valve core 6, on spherical valve core 6, there is cross through hole 7, drain line 9 is arranged on a side of valve body 3.Adjustable ring 4 is threaded connection in the left end screw of valve body 3, and adjustable ring 4 compresses left seal receptacle 5, and rotating adjustment ring 4 can regulate the tightness degree that contacts of left seal receptacle 5, right seal receptacle 8 and spherical valve core 6, guarantees to seal reliably and with long-term.Left seal receptacle 5, right seal receptacle 8 are nonmetals, and plasticity is good, easily sealing, and it is convenient after damaging, to change.
During sampling, supporting key is opened anti-theft lock 2 could rotary spherical spools 6, make the setting-out of aliging with the duct of left seal receptacle 5, right seal receptacle 8 of cross through hole 7 on spherical valve core 6.With supporting key rotation, pin after anti-theft lock 2, the cross through hole 7 on spherical valve core 6 disconnects with the duct of left seal receptacle 5, right seal receptacle 8.
