Description
Technical field
The present invention relates to a kind of oil pumps, more particularly, to a kind of quiet 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, move it is all
That " 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, are moved in valve
Equipped with through-hole, through-hole is entered by necking down hole by exercising crude oil on the through-hole lower end necking down hole of the stifled dynamic valve of the ball sealing in through-hole or ball
And reach dynamic valve top；It is equipped with hole in the middle part of quiet valve in oil pipe, the hole of quiet valve is blocked up by another ball sealing or opens the hole；
It drives sucker rod to move back and forth valve in oil pipe by horse head when operation, further makes the crude oil in the oil pipe of quiet valve top
Constantly simultaneously, the final crude oil obtained in oil pipe is lifted for aggregation；Detailed process is: when dynamic valve uplink, quiet valve is by oil pipe
The pressure effect of the dynamic upward oil pipe of valve, ball just block the through-hole of dynamic valve, and another ball uplink of quiet valve opens the hole, former
Oil enters 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 blocks up institute
Hole is stated, 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, moves all
You constantly pump, and the ball for moving valve constantly replaces with another ball of quiet valve to be closed and open, and crude oil is not in well
It is disconnected 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.
Summary of the invention
In order to overcome the shortcomings in the background art, the present invention discloses a kind of quiet valve structure of thickened-oil pump, using weight compared with
The inserted link of big plugging block controls the fuel feed hole of quiet valve, and the self-cleaning of inserted link is obtained using inserted link control and the friction of fuel feed hole hole wall,
Realize preferable sealing effect.
For achieving the above object, the present invention adopts the following technical scheme:
