Abstract
The invention provides a piston type unloading-free sampling device. The piston type unloading-free sampling device comprises a quick coupling. The conical head side of the quick coupling is connected with a nut. The other side of the quick coupling is in threaded connection with a front plug. The front plug is in threaded connection with a cylinder barrel. The other side of the cylinder barrel is in threaded connection with a rear cover. A trapezoidal thread through hole is formed in the center of the rear cover and is in threaded connection with a screw rod. The screw rod is connected with a shaft check ring through a thrust bearing and a baffle ring. The excircle diameter of the baffle ring is larger than that of the thrust bearing. The outer cylindrical surface of the baffle ring is connected with a counter bore formed in the center of a piston in a clearance fit mode. The end face of the baffle ring makes contact with a step surface of the counter bore in the piston. The end of the shaft check ring is fixed by the screw rod and does not make contact with the counter bore in the piston. The end face, connected with the cylinder barrel, of the front plug is provided with a by-pass hole communicated externally, and the communication portion is provided with a needle valve. According to the piston type unloading-free sampling device, the problems that in the injection well sampling process in the past, polymer solution waste, environmental pollution and the like are caused by long-time unloading are solved, precision and representativeness of samples are improved.

On the end face that front plug in such scheme is connected with cylinder barrel, have by-pass prot and be communicated with outside, be communicated with position and be provided with needle valve; Bonnet center has trapezoidal thread through hole and is connected with threads of lead screw, replaces with, and bonnet center has through hole, and in through hole, interference fit connects copper sheathing, and copper sheathing adopts ormolu material to make, and copper sheathing center has trapezoidal thread and is connected with threads of lead screw; The axle head that leading screw is exposed at outside bonnet cuts into square head, and square head outer cover has torsion tongue piece, and torsion tongue piece endoporus and square head are connected, and two thin slices are extended in the outside of torsion tongue piece.
The present invention has following beneficial effect: solved in the past in Injection Well sampling process, due to long-time emptying, the polymer solution waste causing, with problems such as environment pollutions, has improved accuracy and the representativeness of sampling sample.
accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is another embodiment of the present invention structural representations.
1-nut in figure, 2-snap joint, plug before 3-, 4-piston, 5-thrust bearing, 6-leading screw, 7-bonnet, 8-square head, 9-cylinder barrel, 10-baffle ring, 11-needle valve, 12-by-pass prot, 13-copper sheathing, 14-torsion tongue piece.
the specific embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
By Fig. 1 in conjunction with shown in Fig. 2, piston type is exempted from emptying sampling device, comprise snap joint 2, the first side coupling nut 1 of circular cone of snap joint 2, plug 3 before snap joint 2 opposite sides are threaded, front plug 3 cylinder barrel 9 that is threaded, the cylinder barrel 9 opposite sides bonnet 7 that is threaded, bonnet 7 centers have trapezoidal thread through hole and are threaded with leading screw 6, piston 4 cylindricals are connected with cylinder barrel 9 endoporus matched in clearance, leading screw 6 is by thrust bearing 5, baffle ring 10 connects by shaft block ring, baffle ring 10 outside diameters are greater than the outside diameter of thrust bearing 5, baffle ring 10 outer cylinder surfaces are connected with the counterbore matched in clearance that piston 4 centers are outputed, baffle ring 10 end faces contact with the step surface of piston 4 counterbores, the leading screw 6 fixedly end of shaft block ring does not contact with the counterbore of piston 4, when piston 4 pressurized extruding baffle ring 10, leading screw 6 does not contact with piston 4, leading screw 6 can be rotated, the axle head that leading screw 6 is exposed at outside bonnet cuts into square head 8, each sealing place is provided with seal.
On the end face that front plug 3 is connected with cylinder barrel 9, have by-pass prot 12 and be communicated with outside, be communicated with position and be provided with needle valve 11.
Piston type is exempted from emptying sampling device and mainly by stainless steel material, is made, leading screw 6 is by medium carbon steel and through modified Quenching Treatment, this device adopts the mode of leading screw 6 propelling pistons 4, and for reducing leading screw friction in motion process, sampler bonnet place selects brass material to be connected with leading screw.
Further, bonnet 7 centers have trapezoidal thread through hole and are threaded with leading screw 6, replace with, bonnet 7 centers have through hole, in through hole, interference fit connects copper sheathing 13, and copper sheathing 13 adopts ormolu material to make, and copper sheathing 13 centers have trapezoidal thread and are threaded with leading screw 6, ormolu has reduced friction factor with being connected of leading screw 6, makes that sampling work is more laborsaving to save time.
Further, the axle head that leading screw 6 is exposed at outside bonnet cuts into square head, square head outer cover has torsion tongue piece 14, torsion tongue piece 14 endoporus and square head are connected, two thin slices are extended in the outside of torsion tongue piece 14, one holds sampler body, on the other hand twists torsion tongue piece 14 can complete sampling work, without by other instruments.
When continuous sampling, Injection Well well head polymer enters in sampler, we first open the needle valve 11 of sampler front end, discharge sampler entrance to the interior residual liquid of piston 4 these segment distances, prevent that last sampling residual liquid from affecting sample examination result, close needle valve 11 and start sampling, because intake wellhead pressure is large, the polymer samples taking out can promote piston and take exercises after 4, simultaneously, the stressed handle by operating personnel's manual rotation sampler of leading screw 6, make leading screw 6 drive piston 4 uniform motion backward, having guaranteed does not have shear stress in Injection Well sampling process, and this installs micro-emptying, every mouthful of well of post workman has shortened in 5 minutes by original 20 minutes sample time, effectively saved operating time when operating personnel sample, the problems such as the polymer waste in minimizing sampling process and environment pollution, protected environment, improved operating efficiency, solved in the past in Injection Well sampling process, due to long-time emptying, the polymer solution waste causing is with problems such as environment pollutions, accuracy and the representativeness of sampling sample have been improved.
