Detailed Description

An embodiment of the invention will be described in detail below with reference to fig. 1, but the invention can be implemented in many different ways as defined and covered by the claims.

Referring to the attached drawing 1, production valve 8 and backpressure valve 7 are connected simultaneously to sampling valve 9, and the staff connects sample elbow 15 when the sample, closes backpressure valve 7, then opens sampling valve 9 and operates, and the utility model provides a split type well head sample separator, set up the transition container of constituteing by the sampling chamber 4 of middle part, degasification room 17 on upper portion and waste oil room 16 of lower part between sampling valve 9 and sample elbow 15, wherein, the body of sampling chamber 4 and degasification room 17 is the hollow cylinder as the space that holds the extraction liquid, the body of waste oil room 16 is hollow hemisphere, waste oil can not be accumulated and saved in its bottom, do benefit to the waste oil of giving off, sampling chamber 4 passes through bolt 3 with degasification chamber 17 and waste oil room 16 respectively and is connected, all set up seal gasket 2 between sampling chamber 4 and degasification chamber 17 and the waste oil room 16.

The utility model discloses a through set up a transition device between sampling valve 9 and sample elbow 15, the harmful gas who contains in the separation extraction liquid, make the sample that flows when gathering by sample elbow 15 smooth, avoid the sample splash, this design is through interconnect's sampling room 4, degasification room 17 and waste oil room 16 realize jointly, the three has different structure and function, but mutually support, realize the purpose of safe and stable sample jointly, this kind of split type design also does benefit to dismantlement and maintenance.

With reference to fig. 1, a straight pipe is arranged at the outer periphery of the sampling chamber 4 and is connected with a sampling valve 9; a sampling ball valve 13 is arranged on the outer periphery of the sampling chamber 4, and an outlet 14 of the sampling ball valve 13 is connected with a sampling elbow 15; a conical partition plate 5 is fixedly arranged inside the sampling chamber 4, and the bottom of the partition plate 5 is provided with an opening.
