Abstract
The utility model relates to a sample valve without discharging empty of the crude oil pipeline. The sample valve comprises a valve body and a valve rod. The valve body is a pipe-box structure, two ends of the valve are provided with a disk seat and a plug respectively. And an annular boss is arranged in the valve body and a gear is arranged outside of the valve body. The gear is connected with the annular boss through the screw thread. The body of the outer periphery connects with a sampling pipeline and the valve rod, connected with the annular boss through the screw thread, is installed in the valve body. A valve core is arranged on the front end of the valve body. The sample valve can take samples from the crude oil pipeline directly. It is no necessary to empty crude oil in the pipe .Therefore the utility model can avoid the waste of crude oil and the pollution of environment and also lightens labor intensity. The sample valve is convenient to repair; the advantages are swift operation, safety and efficient sampling.
Description
Technical field
The utility model belongs to oil field oil recovery valve member technical field, and particularly a kind of crude oil pipeline is exempted from the emptying sample valve.
Background technology
The oil field is in carrying out oil extraction, and in the defeated process of the crude oil of well mouth of oil well extraction and collection, the extraction oil sample of need layouting is usually chemically examined, and to grasp the situation of down-hole oil reservoir and extraction fluid, in time takes measures, and guarantees normally carrying out of oil extraction.In the prior art, generally be on original pipeline, to connect the arm of draining the oil, and gate valve is set, when sampling, open valve and access oil sample.But, because the arm inner product of draining the oil has old crude oil, can not reflect in the pipeline situation of oil stream in real time, therefore when each sampling, must open valve and will drain the oil earlier and accumulate the whole emptying of crude oil in the arm, just can access oil sample then.Like this, not only time-consuming, and cause the pollution of crude oil waste and environment easily.Particularly in the winter time, the crude oil in the arm of draining the oil freezes easily, and the pipeline purging that often needs to build the pressure could be taken a sample after it is melted, and bothers very much, and brings potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of need not can directly access oil sample with the crude oil emptying in the arm of draining the oil, and conveniently crude oil pipeline is exempted from the emptying sample valve.
Realize that the technical scheme that the purpose of this utility model is taked is: this sample valve comprises valve body and valve rod, valve body is a pipe box shape structure, the one end has valve seat, and the other end is equipped with plug, is provided with annular boss in the valve body, the outside is provided with the retaining edge, and be coated with the attaching nut, and the outer circumferential sides of valve body connects and is communicated with the sampling drain line, and valve rod is installed in the valve body, and be connected with described annular boss by screw thread, the front end of valve rod is provided with spool.
Described valve rod adopts universal the connection with spool.
Described valve rod adopts two sections docking structures.
Described valve rod rear end is provided with handle.
Exempt from the emptying sample valve according to what such scheme was made, valve body is put in the crude oil pipeline, thereby can directly in crude oil pipeline, take a sample, need not to drain the oil and accumulate crude oil emptying in the arm, avoided the waste of crude oil and the pollution of environment thus, and alleviated labour intensity, it is convenient that this sample valve also has installation and maintenance, simple and quick, safe and reliable, sampling operating efficiency advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the emptying sample valve of exempting from of the present utility model has the valve body 1 of a pipe box shape, and the front end of valve body 1 is provided with valve seat 5, and the centre of valve seat 5 is provided with oil flow channel hole 6, and plug 11 is equipped with in the rear end of valve body 1, is provided with an annular boss 2 in the valve body 1.Be provided with retaining edge 9 in the outside of valve body 1, perhaps step structure made in the outside of valve body 1.Rear portion at retaining edge 9 is coated with attaching nut 3, is used for valve body 1 and drains the oil being connected of arm with crude oil pipeline, and the outer circumferential sides of valve body 1 connects and also is communicated with the drain line 10 of taking a sample, the derivation of the fluid that is used to take a sample.Be coated with valve rod 4 in valve body 1, this valve rod 4 is connected with described annular boss 2 by screw thread, and the front end of valve rod 1 is connected with the spool 7 that cooperates with valve seat 5, and turn valve rod 4 can realize exempting from the keying of emptying sample valve.Valve rod 4 can adopt universal the connection with spool 7, so that the closely cooperating of spool 7 and valve seat 5.Valve body 1 outside is stretched out in the rear end of valve rod 4, and its external part is equipped with handle 12.Valve rod 4 also can adopt two sections docking structures, and the docking site is adopted and is threaded, and holds out against by holding screw 8, when damaging when spool 7 and with valve rod 4 connecting portions, as long as change the leading portion of valve rod 4.
Operating principle: this exempts from the emptying sample valve in use, is inserted into petroleum pipeline and drains the oil in the arm, and the front end of exempting from the emptying sample valve is injected in the petroleum pipeline, attaching nut 3 is screwed with the arm of draining the oil again, and promptly finishes the installation of exempting from the emptying sample valve.When carrying out crude oil sampling, as long as turn handle 12, open and exempt from the emptying sample valve, crude oil in the petroleum pipeline is promptly flowed in the valve body 1 by the gap of the fluid access opening 6 on the valve seat 5 between valve seat 5 and spool 7, and through 10 outflows of sampling drain line, just can finish sampling, then if turn handle 12 will exempt from the emptying sample valve and close.Owing to exempt from the emptying sample valve and directly put in the crude oil pipeline, thereby need not and to accumulate crude oil emptying in the arm of draining the oil, just can take the crude oil sample that flows in real time in the crude oil pipeline, guarantee the accuracy of taking a sample.
