Description
[technical field]
The present invention relates to a kind of oil pumps, more particularly, to a kind of dynamic valve structure of thickened-oil pump.
[background technique]
Known, thickened-oil pump is to obtain oil well Crude Oil to be raised to the tool on ground by underground, mainly by sucker rod, dynamic
Valve " piston ", quiet valve, oil pipe and oil recovery horse head are constituted, and wherein the sucker rod lower end in oil pipe connects dynamic valve, move valve
In be equipped with through-hole, entered by exercising crude oil on the through-hole lower end necking down hole of the stifled dynamic valve of ball sealing in through-hole or ball by necking down hole logical
Hole simultaneously reaches dynamic valve top；It is equipped with hole in the middle part of quiet valve in oil pipe, is blocked up described in hole or the unlatching of quiet valve as another ball sealing
Hole；It drives sucker rod to move back and forth valve in oil pipe by horse head when operation, further makes in the oil pipe of quiet valve top
Crude oil is constantly assembled simultaneously, the final crude oil lifting obtained in oil pipe；Detailed process is: when dynamic valve uplink, quiet valve is by oil
The pressure effect of the dynamic above oil pipe of valve in pipe, ball just block the through-hole of dynamic valve, described in another ball uplink opening of quiet valve
Hole, crude oil enter the shoe cream room formed between dynamic valve and quiet valve；In the decline of dynamic valve, at this moment another ball sealing of quiet valve
The hole is blocked up, ball uplink leaves the necking down hole of mouth under dynamic valve through-hole, and at this moment the crude oil in shoe cream room is expelled to dynamic valve top,
Dynamic valve constantly pumps, and the ball of dynamic valve constantly replaces with another ball of quiet valve to be closed and open, former in well
It is oily constantly to enter oil pipe, thus on be advanced into oil pipe, finally reach ground.
Existing thickened-oil pump ball-type move valve and quiet valve there are ball self weight it is smaller cannot preferable plugging hole, sand or its
Its object will also result in the poorly sealed of hole, lack self-purification capacity, and the ball of quiet valve is often touched during dynamic valve downlink,
It is easy the decline for making deformation of ball further result in tightness.
