Abstract

Disclosed is an emptying avoidance theftproof sampler which comprises a valve body, a plunger body, a spring, a valve core, a valve base, a top-open plunger, a sampling plunger and a screw plug; one end of the valve base is connected with the valve body and the other end of the valve base is connected with the plunger body; the top open plunger is mounted in the plunger body; the sampling plunger is mounted in the top open plunger; the screw plug is mounted on the external end of the plunger body; the valve core is arranged on the valve base in the valve body; the spring is arranged between the inner end surface of the valve body and the valve core. The emptying avoidance theftproof sampler is provided with the functions of emptying avoidance and theft protection, and is widely applicable to the sampling systems in the oil wells.

Description

Exempt from the antitheft sampler of emptying
One, technical field
The utility model relates to the oil exploitation sample valve, particularly a kind of antitheft sampler of emptying of exempting from.
Two, background technology
The traditional oil well sample valve in oil field is generally common ball valve, is installed on the back pressure pipeline by traditional connected mode.This sample valve exists following shortcoming or deficiency: must take a sample after the first emptying when 1. taking a sample, so just cause the waste of petroleum resources and the pollution of environment; 2. theftproof performance is poor, is easy to be opened drain the oil or shed valve, causes environmental protection indemnity and cost environment protection treating expense simultaneously; 3. very big owing to destroying the workload of resuming production, increase enterprise's added burden; 4. reduce rate when driving a well, cause economic loss.
Three, summary of the invention
The purpose of this utility model provides a kind of improved antitheft sampler of emptying of exempting from, adopt dual piston structure, the shortcoming or the deficiency that can overcome effectively or avoid existing in the above-mentioned prior art are taked oil sample smoothly and effectively, avoid the emptying sampling effectively, stop theft and environment pollution.
The antitheft sampler of emptying of exempting from described in the utility model, comprise valve body, plunger body, spring, spool, valve seat, back down plunger, sampling plunger, plug, described valve seat one end is connected with valve body, the other end is connected with plunger body, the described plunger that backs down is installed in the plunger body, and the sampling plunger is installed on and backs down in the plunger, and the plunger body outer end is equipped with plug, on the valve seat in the valve body spool is installed, described spring is installed between valve body inner face and the spool.
Wherein, described plunger body middle part is provided with oil outlet, and the end is provided with internal thread.The described plunger that backs down is shoulder hole structure in being provided with, and its large aperture section is provided with internal thread, and the end is provided with external screw thread, and wall is provided with flowing hole, and section end, small-bore is provided with slot, contacts with spool, and large aperture end external screw thread is meshed with the plunger body internal thread.Described sampling plunger be one with back down the corresponding to stepped cylindrical body of plunger endoporus, reduced diameter section is packed in the plunger body, enlarged diameter section is provided with external screw thread, is meshed with the internal thread that backs down plunger.Described valve body is provided with oil-through hole.
The utility model has following advantage compared with prior art:
1, adopt the double plunger structure, the history of the emptying that is through with sampling reduces and pollutes and waste.
2, have triple anti-theft features, the incident of avoiding destroying and steal national resources is given birth to, and has avoided simultaneously owing to the extensive work that resumes production that destroys and theft causes, and has improved rate when driving a well.
3, have band and press sampled functions.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Five, the specific embodiment
Consult accompanying drawing, a kind of antitheft sampler of emptying of exempting from, comprise valve body 1, plunger body 7, spring 2, spool 4, valve seat 6, back down plunger 8, sampling plunger 10, plug 11, valve seat 6 one ends are connected with valve body 1, and the other end is connected with plunger body 7, back down plunger 8 and are installed in the plunger body 7, sampling plunger 10 is installed on and backs down in the plunger 8, plunger body 7 outer ends are equipped with plug 11, on the valve seat 6 in the valve body 1 spool 4 are installed, and spring 2 is installed between valve body 1 inner face and the spool 4.
Plunger body 7 middle parts are provided with oil outlet 9, and the end is provided with internal thread.Back down plunger 8 and be shoulder hole structure in being provided with, its large aperture section is provided with internal thread, and the end is provided with external screw thread, and wall is provided with flowing hole 12, and section end, small-bore is provided with slot 5, contacts with spool 4, and large aperture end external screw thread is meshed with plunger body 7 internal threads.Sampling plunger 10 be one with back down the corresponding to stepped cylindrical body of plunger 8 endoporus, reduced diameter section is packed in the plunger body 7, enlarged diameter section is provided with external screw thread, is meshed with the internal thread that backs down plunger 8.Valve body 1 is provided with oil-through hole 3.
