Abstract

The utility model relates to a sampling bucket with a threaded cover. The sampling bucket comprises a sample bucket and a bucket cover. The lower end of the bucket cover is provided with an internal thread. The upper edge of the sample bucket is provided with an external thread. The internal and external threads are single-line common coarse threads the same in diameter and thread form. After screwing, two ends and the threads function in sealing. The sampling bucket is well airtight, capable of effectively preventing pouring of oil samples, friendly to accurate sampling and friendly to environment. The sampling bucket has the advantages of simple and reasonable design and convenience in use.

Description

The sample bucket of threaded lid

Technical field

The utility model relates to a kind of sample bucket of oil production equipment auxiliary technical field, particularly a kind of threaded lid.

Background technology

Sample bucket is requisite utensil in the oil field equipment, is mainly used to splendid attire and chemically examines from the oil sample that the beam well well head takes out.At present the sample bucket that uses is that tin-plate is made, sample bung plug formula, and sealing effectiveness is relatively poor, and under strenuous exercise or the situation of toppling over, oil sample will flow out, and not only causes oil analysis inaccurate, and can cause environmental pollution.

The utility model content

It is better that the purpose of this utility model provides a kind of sealing effectiveness, can prevent from that oil sample from inclining to spread, and avoids causing the sample bucket of the threaded lid of environmental pollution.

Realize that the technical scheme that the purpose of this utility model is taked is: this sample bucket comprises sample bucket and sample bung, wherein, the lower edge of sample bung is negative thread, the upper edge of sample bucket is outside thread, internal and external screw thread is same diameter, with the common coarse-pitch thread of tooth form single line, when spinning together, two end faces and screw thread play sealing function.

The sample bucket of the threaded lid of making according to such scheme, sealing effectiveness is better, can prevent from effectively that oil sample from inclining to spread, and can not influence the sampling accuracy and cause environmental pollution.This sample bucket simplicity of design is reasonable, easy to use.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Referring to Fig. 1, the sample bucket of threaded lid of the present utility model, comprise sample bucket 1, sample bung 2 and screw thread 3, wherein, the lower edge of sample bung 2 is negative thread, and the upper edge of sample bucket 3 is outside thread, and two screw threads are same diameter, with the common coarse-pitch thread of tooth form single line, when spinning together, two end faces and screw thread play sealing function.When using at the scene, earlier sample bung 2 is screwed off, got oil sample after, sample bung 2 screw-in sample buckets 1 are tightened, what oil sample will be complete is sealed in the sample bucket 1.

Claims (1)

1. the sample bucket of a threaded lid comprises sample bucket and sample bung, it is characterized in that: the lower edge of sample bung is negative thread, and the upper edge of sample bucket is outside thread, and internal and external screw thread is same diameter, with the common coarse-pitch thread of tooth form single line.
