Abstract
The utility model discloses an oil extraction sampling valve for measuring wellhead pressure which comprises a valve body, a by-pass oil outlet duct, a valve plug rod, a handle and a sampling oil outlet, and is characterized in that: the by-pass oil outlet duct is provided with a pressure measuring gauge, and a channel of the sampling oil outlet is provided with a valve. When extracting oil and sampling to measure the pressure in winter, dead oil which freezes and blocks the duct does not exist in the oil liquid. Moreover, the utility model can measure the pressure at any moment during oil extraction and sampling, and has convenient use.
Description
Technical field:
The utility model relates to a kind of oil recovery sample valve, but especially the well head pressure of measuring well mouth pressure is measured the oil recovery sample valve.
Background technology:
Usually need to take a sample in the oil producing operation at present, present sample valve, as the disclosed production wellhead sample valve of Chinese patent CN2632308Y, comprise valve casing, valve casing is provided with the screw thread that can be connected with the well head oil pipe outward, be provided with axial sampling oil duct in the valve casing, bypass oil discharge passage and valve core rod and handle, this sample valve can solve dead oil blocking problem when recovering the oil sampling winter well, but because pressure meter is mounted on the oil pipeline, operation pipe Nei Yiyin has dead oil and freezes obstruction under the low temperature in the winter time, can't learn the well head pressure data conditions when forming sampling.
Summary of the invention:
The purpose of this utility model be to provide a kind of sampling of can either recovering the oil in the winter time, again can the measuring well mouth pressure well head pressure measure the oil recovery sample valve.
The utility model comprises a valve body, bypass oil road, valve core rod, handle and sampling oil outlet, is characterized in being provided with pressure measuring instrument on the bypass oil road, and sampling oil outlet passage is provided with valve.
Compared with prior art, when the utility model recovered the oil sampling and measuring pressure in the winter time, fluid freezed with regard to not having dead oil to stop up, and can record pressure at any time when recovering the oil sampling, and easy to use.
Description of drawings:
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
1 is the valve body handle shown in the figure, and 2 is end cover, and 3 is valve body, and 4 is the bypass oil road, and 5 is pressure measuring instrument, and 6 are the sampling oil outlet, and 7 is plunger valve.
The specific embodiment:
Embodiment 1:
With reference to accompanying drawing 1～2, comprise bypass oil road 4 and sampling oil outlet 6 on valve body 3, the valve body, be provided with pressure measuring instrument 5 on the bypass oil road, sampling oil outlet passage is provided with plunger valve 7, one end of valve body armrest handle 1 is provided with end cover 2, is provided with sealing mat in the end cover.During use, the plunger valve that the measuring well mouth pressure is closed oil outlet passage one side can be read the data on the pressure meter, and then opens plunger valve and go out oil sample with regard to desirable.
Embodiment 2:
Comparing difference be the to take a sample valve of oil outlet passage with embodiment 1 is gate valve.
