Be evenly equipped with four holes on the said central tube sidewall; Central tube is provided with equalizing valve outward, and equalizing valve comprises the centralizer body that is socketed on the central tube and covers said hole, and centralizer body is provided with brake pad outward; Be provided with spring between brake pad and the centralizer body; The centralizer body two ends are provided with the pressure ring of axial restraint brake pad, and the equalizing valve upper end is provided with hook, and said hook hangs over scraping on the pin of central tube side.
The invention has the beneficial effects as follows:
1) present device simple in structure, easy for installation, be convenient to the operation;
2) the present invention can prevent effectively that flushing fluid from getting into the stratum, pollutes even the obstruction oil reservoir, and the stratum is not had injury;
3) the present invention can maintain the seepage flow situation of layer inner fluid, thereby realizes the purpose of steady output of oilwell;
4) the present invention has the function of de-plugging simultaneously.
Below in conjunction with Figure of description the present invention is done further description.
