A valve seat is fixedly mounted in an inner cavity on the right portion of the valve body, the big end of the concentric reducer is fixedly mounted with the right end of the valve body, the small end of the concentric reducer is fixedly mounted with the left end of the sampling pipe, the right end of the sampling pipe is fixedly provided with the sample collecting head, a liquid inlet is arranged on the sample collecting head, the left end of the valve body and the right end of the hollow plug are fixedly connected, a mounting hole is arranged at the left end of the valve body, and a through hole is arranged at the left end of the valve seat. The liquid collecting type bidirectional switch antifreeze sampler is reasonable and compact in structure and convenient in use, can not be easy to be blocked but can collect more actual liquid samples because a sample collecting port can extend between an oil outlet vertical pipe and an oil nozzle bush to collect liquid samples on a turbulent section, and a front valve needle and a rear valve needle which are designed in the device can not be in misoperation so as to prevent oil splashing from a sampling nozzle, thereby reducing hidden dangers of environment pollution.
Description
One, technical field
The utility model relates to field produces wellhead sampling device, is the antifreeze sampler of a kind of liquid collecting formula two-way switch.
Two, background technology
The mode of oil field shaft mouth sampling at present has two kinds: the one, and gate valve control, by the open degree of the manual shift gate valve liquid of taking a sample, its advantage is non-leakage, but because the pipe nipple, gate valve, the sampling mouth that are connected with hollow plug all expose outside insulation can, freezes easily winter to block up and cause and can not take a sample; The 2nd, existing known common " antifreeze sampling liquid " is installed, its advantage is that sampling mouth, gate valve, pipe nipple, hollow plug are integrated in one, expose outside insulation can have only plug, the mouth small part of taking a sample, can reduce and freeze stifled phenomenon.But because the poor sealing performance between valve seat and the needle, easy seepage, to flow to one section horizontal channel with up-to-date style liquid and just arrive the sampling mouth, the sample liquid of horizontal segment can not in time drain behind the closing gate valve, easily cause winter freeze stifled, be unfavorable for the collection of sample liquid, and all there is common shortcoming in above two kinds of methods: its liquid of can only taking a sample under stabilization of fluidized, because fluid profit when flowing out the flow line standpipe closely begins to separate, most of water enters flow line from standpipe earlier, moisture few fluid slowly flow to the sampling mouth as analyzing liquid sample through the sampling passage, make moisture on the low sidely, cause and do not conform to the actual conditions, and the moisture former oil mass of calculating according to well head production fluid amount on the low side is just higher, the actual former oil mass of receiving with oil gathering station is not inconsistent, thereby has strengthened the well head oil mass and the oil gathering station oil mass is counted difference.To contain aqueous humor untrue because well head is obtained, just is unfavorable for individual well, block analysis.Oil well sampling liquid is regular work, maloperation occurs and the mouth splash fluid of taking a sample easily, thereby pollutes problem of environment.
Three, summary of the invention

Can according to actual needs the antifreeze sampler of above-mentioned liquid collecting formula two-way switch be made further optimization and/or improvements:
As shown in Figure 1, be installed with on the valve rod 2 of body cavity 11 right parts and be the narrow left tapered needle valve 16 in the left wide right side, like this, when valve rod 2 moves up, left side tapered needle valve 16 can be blocked the passage between valve seat 7 and the valve body 1, when valve rod 2 moved down, right tapered needle valve 13 can be blocked the passage between valve seat 7 and the concentric reducer, so just can not be because of the maloperation mouth 14 splash fluid of taking a sample.
As shown in Figure 1, body cavity 11 is the narrow toroidal in the left wide right side, is convenient to quick emptying sample liquid like this, and it is stifled to prevent that residual liquid from freezing.
As shown in Figure 1, for the ease of rotation valve rod 2, the left end of valve rod 2 is installed with handle 17.
As shown in Figure 1, the left end top of valve body 1 is installed with emptying plug 18, and like this, when sampling mouth 14 took place to stop up, turning valve body 1 was opened emptying plug 18 then, loads onto another sampling mouth 14 and can use.
As shown in Figure 1, in order to increase sealing, between the inwall of valve rod 2 and mounting hole 9, oil-resistant seal ring 19 is installed.
As shown in Figure 1, the left part of body cavity 11 has inner convex platform 20, between the left part of the valve seat 7 in through hole 10 outsides and the right part of inner convex platform 20 pad 21 is installed.
As shown in Figure 1, for the ease of installing and maintenance, be installed with valve seat 7 by screw thread in the inner chamber of valve body 1 right part, the right-hand member of the stub end of concentric reducer 4 and valve seat 7 is fixedly installed togather by screw thread, the little head end of concentric reducer 4 and the left end of stopple coupon 5 are fixedly installed togather by screw thread, the right-hand member of stopple coupon 5 is installed with collection sample head 6 by screw thread, in valve body 1 bottom outer lug boss 22 is arranged, and the inboard outside with outer lug boss 22 of the right part of hollow plug 3 is fixed together by screw thread.
As shown in Figure 1, the right-hand member of collection sample head 6 is equipped with sand filtering net, sand filtering net is installed can be prevented effectively that the grains of sand from entering sampler and causing and be not closed completely.
As shown in Figure 1, on valve body 1 right part, tapered thread 15 is arranged, unload the plug on the sampling passage, valve body 1 is fixedly mounted on the sampling passage by tapered thread 15.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The use of the utility model most preferred embodiment: unload the plug on the sampling passage, by tapered thread 15 the utility model is installed in the sampling pipe, to collect sample head 6 extends between flowline riser and the oil nozzle cover, collect sample liquid at turbulent face place, the sample liquid that is filtered out the grains of sand by sand filtering net is discharged from sampling mouth 14 behind stopple coupon inner chamber, concentric reducer inner chamber 12, valve base cavity, body cavity 11, gets the liquid back forward or reverse handle 17 that finishes and all can block passage.Do not need emptying row dead oil during following sub-sampling, because be grab sample, sample liquid is after stopple coupon oil and water separation, and water mostly is deposited on the bottom of concentric reducer inner chamber 12, does not influence sub-sampling down.
