Abstract
The utility model relates to a sampling valve for oil pipeline which comprises a pipeline, a welded pipe, a valve body, a press cap and a valve stem; wherein the welded pipe is arranged in the pipeline, the valve body is connected with the welded pipe, the valve stem is mounted in the valve body, the external screw thread of the valve stem is connected with the internal screw thread of the valve body, the press cap is connected with the external screw thread of the valve body, the left taper surface of the valve stem is in contact with the left internal taper surface of the valve body and an intercommunication groove is provided at the lower side surface of the valve body. When sampling, the valve stem is rotated, the left taper surface of the valve stem leaves the left internal taper surface of the valve body, the raw oil in the pipeline flows out through the intercommunication groove of the lower side surface of the valve body. Because the volume in the intercommunication groove of the lower side surface of the valve body is small, the sample of raw oil can be directly gotten without the need for emptying and does not cause waste of raw oil or the environmental pollution. The sampling is convenient and fast.
Description
One, technical field
The utility model is the detection device on a kind of petroleum pipeline, particularly a kind of petroleum pipeline sample cock.
Two, background technique
Petroleum pipeline is when conveying crude oil, to chemically examine the crude oil sampling in the pipeline at any time, between present sample cock and the probe tube front end certain volume space is arranged, for improving sampling quality, guarantee the accuracy of chemical examination, sample examination again be to bleed off behind the crude oil in this part space during sampling earlier, crude oil waste and environmental pollution caused, sampling work trouble.
Three, summary of the invention
The purpose of this utility model is a kind of petroleum pipeline sample cock of design, makes its direct sample, can not cause crude oil waste and environmental pollution, and sampling work is convenient, fast.
The purpose of this utility model is achieved in that by pipeline, welded tube, valve body, pressure cap, valve rod to be formed, welded tube is installed in the pipeline, valve body connects with welded tube, valve rod is installed in the valve body, the valve rod outside thread connects with the internal thread of valve body, pressure cap connects with the outside thread of valve body, and valve rod left end conical surface contacts with the inner conical surface in a valve body left side, and the valve body downside has UNICOM's groove.
The beneficial effects of the utility model are: almost do not have volume space between sample cock and the probe tube front end, can directly get crude oil sample, do not need emptying, can not cause crude oil waste and environmental pollution, sampling work is convenient, fast.
Four, description of drawings
Accompanying drawing is the utility model embodiment's a erection drawing.
Five, embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
Embodiment of the present utility model is made up of pipeline 1, welded tube 2, valve body 3, pressure cap 4, valve rod 5, welded tube 2 is installed in 1 li of pipeline, valve body 3 connects with welded tube 2, valve rod 5 is installed in the valve body 3, valve rod 5 outside threads connect with the internal thread of valve body 3, pressure cap 4 connects with the outside thread of valve body 3, and valve rod 5 left end conical surfaces contact with valve body 3 left inner conical surfaces, and valve body (3) downside has UNICOM's groove.
During sampling, rotary valve rod 5, valve rod 5 left end conical surfaces leave valve body 3 left inner conical surfaces, crude oil in the pipeline 1 goes out from UNICOM's concentrated flow of valve body 3 downsides, because the volume of UNICOM's groove of valve body 3 downsides is very little, so can directly get crude oil sample, does not need emptying, can not cause crude oil waste and environmental pollution, sampling work is convenient, fast.Valve rod 5 backways are spacing by pressure cap 4.The effect of welded tube 2 is after valve body 3 damages, and can take off valve body 3 and change.
Claims (1)
1, a kind of petroleum pipeline sample cock, form by pipeline (1), welded tube (2), valve body (3), pressure cap (4), valve rod (5), it is characterized in that: welded tube (2) is installed in pipeline (1) lining, valve body (3) connects with welded tube (2), valve rod (5) is installed in the valve body (3), and valve rod (5) outside thread connects with the internal thread of valve body (3), and pressure cap (4) connects with the outside thread of valve body (3), valve rod (5) left end conical surface contacts with the left inner conical surface of valve body (3), and valve body (3) downside has UNICOM's groove.
