Description
【Technical field】
The present invention relates to a kind of oil pump, more particularly, to a kind of quiet valve structure of thickened-oil pump.
【Background technology】
Known, thickened-oil pump is to obtain the instrument that oil well Crude Oil is raised to ground by underground, mainly by sucker rod, dynamic valve
" piston ", quiet valve, oil pipe and oil recovery horse head are formed, the dynamic valve of sucker rod lower end connection wherein in oil pipe, are set in dynamic valve
There is through hole, block up enforcement crude oil on the through hole lower end necking down hole or ball of valve by the ball sealing in through hole enters through hole simultaneously by necking down hole
Reach dynamic valve top；Hole is equipped with 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；Make
Drive sucker rod valve is moved back and forth in oil pipe by horse head during industry, further make crude oil in the oil pipe of quiet valve top not
Disconnected aggregation simultaneously, finally obtains the crude oil lifting in oil pipe；Detailed process is：When dynamic valve uplink, quiet valve is moved by oil pipe
The pressure effect of the upward oil pipe of valve, ball just block the through hole of dynamic valve, and another ball uplink of quiet valve opens the hole, crude oil
Into the shoe cream room formed between dynamic valve and quiet valve；When dynamic valve declines, at this moment another ball sealing of quiet valve blocks up described
Hole, ball uplink leave 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, move valve
Constantly pump, the ball of dynamic valve constantly replaces with another ball of quiet valve closes and open-top, and crude oil is continuous in well
Into oil pipe, thus on be advanced into oil pipe, finally reach ground.
Existing thickened-oil pump ball move valve and quiet valve there are ball dead 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,
Deformation of ball is easily set to further result in the decline of tightness.
【The content of the invention】
In order to overcome the shortcomings of in background technology, the present invention discloses a kind of quiet valve structure of thickened-oil pump, utilizes the larger envelope of weight
The inserted link of sprue 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, is realized
Preferable sealing effect.
For achieving the above object, the present invention adopts the following technical scheme that：
A kind of quiet valve structure of thickened-oil pump, including oil pipe, quiet valve, plugging block, dynamic valve and sucker rod, quiet valve are fixed on
Oil pipe lower part, is equipped with fuel feed hole in the central panel of quiet valve, and the lower end of plugging block is equipped with the inserted link for matching the fuel feed hole, envelope
Vertical hole is equipped with to lower part in the middle part of the upper surface of sprue, two inclined hole A are penetrated through the bottom hole in the vertical hole by two upper lateral part of inserted link；In oil pipe
The top of quiet valve is equipped with dynamic valve, coordinates plugging block inserted link to be opened with quiet valve fuel feed hole being equipped with the middle part of dynamic valve on vertical hole
When close or plugging mechanism that when plugging block inserted link and quiet valve oil inlet bore closure opens, the upper end connection oil pumping of the dynamic valve
The lower end of bar.
The quiet valve structure of the thickened-oil pump, upper conical face, the lower end of plugging block are equipped with the upper end outer rim of plugging block
Outer rim is equipped with inferior pyramidal face.
The quiet valve structure of the thickened-oil pump, the inferior pyramidal face outer rim in upper conical face to the lower end of plugging block, which is equipped with, is in
Radial a plurality of raised item A.
The quiet valve structure of the thickened-oil pump, is equipped with relative to closure between the lower end of plugging block and the upper end of inserted link
The necking segment of block.
The quiet valve structure of the thickened-oil pump, back taper A is equipped with the lower end outer rim of inserted link.
The quiet valve structure of the thickened-oil pump, the dynamic valve include dynamic valve pipe, necking down bar, thin bar and closure set,
The upper end of dynamic valve pipe is equipped with necking down bar, is equipped with thin bar in the upper end of necking down bar, and the upper end both sides of the thin bar are respectively equipped with convex
Rise, the connection screw thread of thin bar upper end is fixedly connected in the middle part of the connector bottom faces of sucker rod lower end has internal thread to what top was set
Blind hole, stand hole equipped with middle part to top in the middle part of the bottom faces of dynamic valve pipe, two inclined hole B stand hole by middle part and penetrate through respectively to contracting
The lower part both sides of neck, are cased with closure set on necking down bar.
The quiet valve structure of the thickened-oil pump, the outer edge surface clearance fit of the endoporus and necking down bar of the closure set.
The quiet valve structure of the thickened-oil pump, raised item B is respectively equipped with the both sides of thin bar, the two raised item B's
External profile diameter is equal with the external profile diameter of necking down bar, and protrusion is respectively equipped with raised item B upper ends.
The quiet valve structure of the thickened-oil pump, back taper B is equipped with the lower end outer rim of dynamic valve pipe.
The quiet valve structure of the thickened-oil pump, what is set respectively in raised item B upper ends is described raised on two raised item B
End punching, the head of a nail of the rivet forms the protrusion after being fixed by rivet.
Due to using technical solution as described above, the present invention has the advantages that：
The quiet valve structure of thickened-oil pump of the present invention, by the present invention in that substituting the ball of original quiet valve with plugging block, makes
Plugging block dead weight increases considerably, and the fuel feed hole of quiet valve is controlled using the inserted link of the larger plugging block of weight, using inserted link control with
The friction of fuel feed hole hole wall obtains the self-cleaning of inserted link, realizes the protrusion of preferable sealing effect, wherein plugging block outer wall surrounding
Bar A forms a plurality of line with oil pipe and contacts, and it is smooth further to obtain the slip of plugging block, and blocks middle part in the block and stand hole and two
" people " the font hole that inclined hole B is formed may insure that valve pipe lower part is moved in the unobstructed entrance of crude oil；The dynamic valve coordinated with the present invention
" Y " the font hole that the two inclined hole A set in pipe and vertical hole are formed may insure that crude oil smoothly enters dynamic valve pipe top, especially
It is that the closure used is sleeved on the travelling of necking down bar and thin bar outer rim so that crude oil can smoothly pass over " Y " font hole, outside thin bar
Dynamic valve pipe top is flowed between wall and closure set endoporus；In the inserted link of plugging block lower part each time and quiet valve oil inlet
The process that pulls and pushes in hole forms self-cleaning to inserted link；And dynamic valve pipe can also make the outer surface of necking down bar with being slidably matched for closure set
Obtain automatically cleaning；Since the dead weight that the present invention sets plugging block is larger, plugging block can bear the touching of dynamic valve pipe lower end and
It will not damage；Sealing effect of the present invention is preferable, and parts are global design, are hardly damaged, and service life is increased considerably.
