The present invention is also provided with upper and lower centralizer 4 at urceolus outer rim radial equipartition.
Operating principle of the present invention is:
When plunger of the present invention arrives well head and clashes into upper fastener, the relative urceolus of plunger center-pole moves, urceolus compresses umbrella sheet, cooperation according to fitting face makes umbrella sheet draw in, tubular permanent magnet and temperature control magnetic sheet attracting, make state keep (state in Fig. 3), now the urceolus external diameter of plunger and the gap of oil pipe become greatly, and the resistance being subject to ascending fluid during whereabouts diminishes.And when plunger drops to shaft bottom, because temperature raises, magnetic temperature sheet loses magnetic conduction ability, permanent magnet loses gravitation because losing magnetic loop, move down at the relative urceolus of effect lower plunger center-pole of spring restoring force, the urceolus fitting face umbrella sheet root that is slidably matched makes umbrella sheet tilt (umbrella cover opens), and shutoff oil pipe cross section, and the elastic force of spring will make umbrella cover maintenance open (state in Fig. 1).Along with plunger is up, temperature declines, and the sector-meeting of magnetic temperature recovers magnetic conduction ability, but because there being certain distance (magnetic pull and distance square be inversely proportional to) apart from permanent magnet, magnetic pull can not overcome elastic force and make urceolus and center-pole generation relative displacement.Until when plunger arrives well head and clashes into upper fastener, center-pole is Compress Spring under inertia force effect, and make permanent magnet and magnetic temperature sheet collide, permanent magnet sucks again on magnetic temperature sheet.
The present invention is very suitable for gas well draining or gas-lift production, and the greatest drawback of the conventional plunger used at present is can only under closing well state, and when namely OIH gas does not move, could fall shaft bottom under gravity, be intermittent duty.And umbrella shape plunger is when umbrella closing, plunger cross-sectional area only has 1/3 of sectional area in tubing string or less, therefore can under the state of responding curve of well, deadweight is relied on to drop to shaft bottom, and downstream rate is faster, circulating cycle issue is more, realizes continuously-running duty, greatly improves the operating efficiency of pump.
