Embodiment
Be described further below in conjunction with accompanying drawing 1, accompanying drawing 2 pairs of the utility model.
This tubing pump, comprise pump lower contact 1, be connected to the standing valve below pump lower contact 1, the pump barrel 2 be fixed on above pump lower contact 1 is screwed by thread seal, be connected to the oil pipe 5 above pump barrel 2, flip sleeve is loaded on the piston 22 in pump barrel 2, be arranged at travelling valve in piston 22 and flip sleeve and be loaded on sliding sleeve 9 in pump lower contact 1, piston 22 upper end is provided with hoel of piston crown 14, it is connected to sucker rod 12 by the piston upper connection 11 that top is fixing, sliding sleeve 9 lower end is provided with spring 10, piston 22 and pump lower contact 1 side are respectively arranged with vent piston oilhole 19 and pump oil leak hole 6.The to-and-fro motion of normal condition lower sucker rod 12 front wheel driving piston 22, spring 10 promotes sliding sleeve 9 and is positioned at top and pump oil leak hole 6 is isolated with the inner chamber of pump lower contact 1.When sucker rod 12 ruptures, piston 22 moves down under gravity and presses sliding sleeve 9 slide downward, now spring 10 is compressed, pump oil leak hole 6 is opened, vent piston oilhole 19 and pump oil leak hole 6 are conducted, profit by draining successively from oil leak hole 19 and pump oil leak hole 6, prevent bumping type pin oil drain under conventional pump, when sucker rod 12 disconnected de-after, sucker rod and 12 pistons 22 drop on blocking impingement holes in pump, cannot throw bar draining, when having caused former well oil pipe, profit overflows and lands, and reduces discharge amount of pollution and workload of removing contamination.
Standing valve it can be comprised being screwed by thread seal and is fixed on standing valve seat 4 below pump lower contact 1, screwed be fixed in standing valve seat 4 inner chamber and bottom is provided with the standing valve cover 7 of through hole and the valve ball 8 be arranged in standing valve cover 7 that slides by thread seal for following structure, and standing valve cover side is provided with side oil outlet.Change side upward into by common tubing pump standing valve cover oil outlet to go out, avoid the foreign material such as silt particle dirt, iron wire iron rust, rubber and enter in standing valve cover, prevent pump from leaking.Travelling valve can for following structure it comprise two to be arranged in piston 22 inner chamber in the middle of round-meshed travelling valve seat 18 be set, be seated the travelling valve ball 15 that diameter on circular hole is greater than circular hole internal diameter respectively, in piston 22 inner chamber and the centre be positioned at above travelling valve ball 15 is provided with the nomadic valve cover 17 of oil outlet 20.Due to the two valve structures adopting two valve balls 8 to be all positioned at piston, and when it is up and down, nomadic valve cover 17 by valve ball 8 upper end carries out spacing to it, and the valve ball 8 preventing conventional construction to be positioned at piston upper end hits the situation generation that mill upper traveling valve cover easily ruptures.
