Four, description of drawings: accompanying drawing is the structural representation of a kind of embodiment of the present utility model.

Five, embodiment:

With reference to accompanying drawing, the utility model comprises gauge outfit 17, metering drive unit (left-half among the figure) and liquid gas part flow arrangement 1 (right half part among the figure) composition.Liquid gas part flow arrangement 1 is to be respectively equipped with a liquid outlet D who is connected with threeway import E on the container 11 of a sealing, the mixing import A that is connected with pipeline, with exhausr port 14, exhausr port 14 is connected by the vent valve interior with being fixed on container 11 of the wireway 12 in the container 11.Exhausr port 14 is provided with joint flange 13.Vent valve comprises valve seat 3, spool 6, spool support 7, valve core link rod 8 compositions.Spool 6 overlaps 5 fitted seal by the pole 4 of valve core link rod 8 hinges with valve seat.Valve core link rod 8 is connected with floating ball rod 2 in being vertically fixed on container 11 by fixed cover 9.Ball float 10 is fixed on the floating ball rod 2, and floating ball rod 2 is by sleeve pipe 15 location of upper and lower settings in the container 11.Container 11 bottoms are provided with base 16.

The metering drive unit is fixing as a whole by bolt link 32 and nut by threeway seat 37 upper flanges, piston chamber's shell 33 and gauge outfit seat 25 lower flanges.The both sides of threeway seat 37 are respectively equipped with into and out of interface E and 0, upwards connect with piston chamber, inwall at threeway seat 37 is with stationary bushing 35, be provided with two and outlet perforation flow-guiding mouth M and N up and down at the close outlet of stationary bushing 0 place, be provided with flow-guiding mouth F near on the stationary bushing 35 at import E place, in stationary bushing 18, be with commutation flow guiding head 36.The cross section of commutation flow guiding head 36 is " H " shape, is respectively equipped with flow-guiding mouth H, G and K, the L (aperture of all flow-guiding mouths is suitable) of two groups of symmetries on the sliding sleeve of both sides, and middle partition has extended upward pod apertures I.The top of pod apertures I is connected with intermediate conductor 31 and connects.Intermediate conductor 31 is housed in piston chamber's shell 33, and the upper end is connected with the gauge outfit driving mechanism, is with intermediate isolating plate 30 at the outer wall of intermediate conductor 31, and intermediate isolating plate 30 inside and outside sliding with the inner wall sealing of intermediate conductor 31 outer walls and piston chamber's shell 33 respectively cooperate.Upper and lower end portion at intermediate conductor 31 is provided with spring positioning and fixing piece and spring 29 respectively.The gauge outfit driving mechanism comprises gauge outfit seat 23, sliding shoe 22, gauge outfit contact 19, gauge outfit back-moving spring 21, gauge outfit sealing gasket, 20 and the sliding shoe locking mechanism.Gauge outfit seat 23 is connected with piston chamber shell 33 by flange 25 downwards, upwards connects gauge outfit fixed mount 18.Vertical direction is equipped with sliding shoe 22 in gauge outfit seat 23, has two groups of grooves on sliding shoe 22 outer walls, and level is equipped with locking mechanism at the low groove place.Locking mechanism comprises and the axis of rolling 27 of groove fit and rolling axle bed 28, back-moving spring 26.For the ease of installing, gauge outfit seat 23 is bolted to connection by two parts up and down.In order to increase sealing, sealing ring 24,34 is installed in the joint portion of junction.

The course of work of the present invention is: the liquid oils from oil well is carried out gas-oil separation through the oil gas shunt earlier; Gas and liquid just are separated into two parts up and down, and when amount of liquid was big, float upwards cut out gas switch, gas is obstructed, and liquid enters measuring container by the below outlet, floats when gas flow increases, the gas autocontrol switch is opened venting, and 0.05MPa pressure is arranged during owing to liquid process meter.So when the gas autocontrol switch was opened venting, liquid was in choked flow condition.At this moment the liquid level uprising gas reduces, and float rising autocontrol switch is closed, and liquid begins to flow.Control with this that liquid road is not flat, gas circuit is not gone rancid, keep the accuracy of metering.Gas is walked around meter by top vent valve and gas outlet and is entered export pipeline.Liquid dock with G by the F of lower part outlet through the commutation flow guiding head, enters the top of liquid measuring vessel by intermediate conductor, promotes the intermediate isolating plate to lower slider, forces the commutate K of flow guiding head of the liquid oils process of division board below to dock with M and enter export pipeline.When sliding into certain position under the division board, the sliding shoe that lower spring promotes to be connected on the centre pipe moves down, and makes commutation flow guiding head M, K choked flow, L, N conducting; G, F choked flow, H, F conducting, liquid oils enters the below of division board again, promotes the intermediate isolating plate and upwards slides, and the liquid oils above the division board is entered export pipeline by L, N after centre pipe refluxes.When the intermediate isolating plate upwards slided into fixed position, the sliding shoe that upper spring promotes on the centre pipe moved up, and the commutation flow guiding head commutates once more and returns to a circulation position.So come and go constantly circulation, the counter A that every circulation primary is installed in the centre pipe top remembers a number.Because the physical dimension of measuring container is fixed, the stroke of intermediate isolating plate is fixed, so that each circulation enters the volumetric flow rate of export pipeline is fixed.According to the numeration of counter, just can calculate total volumetric flow rate.If equipment goes wrong, hypertonia, protective device is opened automatically, pipeline is led directly to play a protective role.

When the commutation flow guiding head walks to top dead centre or lower dead center, its upper and lower all has a hole relative with the hole on the stationary bushing logical, and be that outlet of an import is logical simultaneously, to guarantee flowing of liquid oils, with the centre pipe top that the slip kink is linked, the sliding shoe of installation is to guarantee that the slip kink walks to top dead centre and lower dead center and can both be fixed on request on certain position and do not misplace.Must put in place in a flash when needing to move.This need be finished by the power assistant spring of the above and below that is installed in the intermediate isolating plate.Motivation package derives from the pressure promotion intermediate isolating plate of oil well and finishes.
