Abstract
An eccentric anti-theft sampling valve comprises a spring seat, a valve body, a spring, a valve ball, a valve seat, a sampling pipe and an eccentric blocking head, wherein the valve seat is mounted inside the valve body, a valve ball seat is disposed on a valve opening of the valve seat, the valve ball is pressed by the spring, the spring seat is connected with left threads of the valve body, the spring is seated on the spring seat, the eccentric blocking head is connected with right large threads of the valve body, small threads are arranged on left side of the right large threads of the valve body, the sampling pipe is mounted on the outside of the valve body, the sampling pipe is also positioned between the valve seat and the small threads, and the sampling pipe is communicated with the valve seat. Because the eccentric blocking head only can be detached by special tools, burglars can not use an existing tool to detach the eccentric blocking head to achieve the purpose of stealing oil. Further, the small threads are left-handed threads, and the burglars can not use the existing tool to be connected with the small threads to push the valve ball open, thereby the burglars can not steal crude oil even the eccentric blocking head is detached. Therefore, economic loss resulting from oil stealing by the burglars can be avoided, because the burglars are unable to steal the crude oil.
Description
One, technical field
The utility model is a kind of device of oil well mouth usefulness, is a kind of eccentric anti-theft sampling valve.
Two, 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.
Three, summary of the invention
The purpose of this utility model is a kind of eccentric anti-theft sampling valve of design, makes thief can not open the valve stolen easily, avoids crude oil stolen, reduces the oilfield economic loss.
The purpose of this utility model is achieved in that by spring base, valve body, spring, valve ball, valve seat, stopple coupon, eccentric block head to be formed, valve seat is installed in the valve body, the valve ball seat is on the valve port of valve seat, spring is pushed down valve ball, spring base is threaded with the left side of valve body, spring base is on spring base, eccentric block head is connected with valve body right side major thread, there is minor thread on the major thread left side, valve body right side, stopple coupon is installed in the valve body outside, stopple coupon is between valve seat and the minor thread, and stopple coupon communicates with valve seat.
Valve seat is that nylon material is made.
Minor thread is a left-hand thread (LHT).
Stopple coupon is welded on the valve body.
The beneficial effects of the utility model are: dismantling eccentric block head will just can finish with specific purpose tool, and thief can't be dismantled eccentric block head with existing instrument, can't reach the purpose of stolen; Because minor thread is left-handed spiral shell, thief also can't be connected with minor thread and pushes valve ball open with existing instrument, therefore, also can't steal crude oil even thief has been dismantled eccentric block head again.So thief can't be stolen crude oil, can avoid the economic loss that causes because of thief theft crude oil.
Four, description of drawings
Accompanying drawing is the wiring layout of the utility model embodiment.
Five, embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
By accompanying drawing as can be known, embodiment of the present utility model is by spring base (1), valve body (2), spring (3), valve ball (4), valve seat (5), stopple coupon (6), eccentric block head (7) is formed, valve seat (5) is installed in valve body (2) lining, valve ball (4) seat is on the valve port of valve seat (5), valve seat (5) is made for nylon material, sealing is reliable, spring (3) is pushed down valve ball (4), spring base (1) is threaded with the left side of valve body (2), spring (3) seat is on spring base (1), and eccentric block head (7) is connected with valve body (2) right side major thread, and there is minor thread (8) on the major thread left side, valve body (2) right side, minor thread (8) is a left-hand thread (LHT), can improve theftproof performance.Stopple coupon (6) is installed in valve body (2) outside, stopple coupon (6) is welded on the valve body (2), stopple coupon (6) is between valve seat (5) and the minor thread (8), and stopple coupon (6) communicates with valve seat (5), can make the oil sample on the pipeline emit removed chemical examination from stopple coupon (6).
The accompanying drawing state is a closed condition, and the oil in the pipeline can not flow out, and can't dismantle eccentric block 7 with existing instrument.When needs are taken a sample, remove eccentric block 7 with specific purpose tool, be connected with minor thread 8 with having then with the specific purpose tool of minor thread 8 identical screw thread button-types, the rotation specific purpose tool, specific purpose tool is walked to the left valve ball 4 is pushed away valve seat 5, and specific purpose tool is with plug for seal between valve body 2 right side major threads and the minor thread, oil sample in the pipeline flows out in the sample bucket through valve seat 5, stopple coupon 6, thereby finish sampling work,, will close the utility model once more with the sampling inverse operation.
Claims (4)
1. eccentric anti-theft sampling valve, by spring base (1), valve body (2), spring (3), valve ball (4), valve seat (5), stopple coupon (6), eccentric block head (7) is formed, it is characterized in that: valve seat (5) is installed in valve body (2) lining, valve ball (4) seat is on the valve port of valve seat (5), spring (3) is pushed down valve ball (4), spring base (1) is threaded with the left side of valve body (2), spring (3) seat is on spring base (1), eccentric block head (7) is connected with valve body (2) right side major thread, valve body (2) right side major thread left side minor thread (8), stopple coupon (6) is installed in valve body (2) outside, stopple coupon (6) is between valve seat (5) and the minor thread (8), and stopple coupon (6) communicates with valve seat (5).
