Detailed description of the invention
The particular content of the present invention is described in detail below in conjunction with the accompanying drawings with specific embodiment.
As it is shown in figure 1, multifunctional pumping rod preventer, including: blowout preventer for sucker rod housing 1, it is arranged on sucker rod blowout-prevention
Device, by the side door assembly 2 of housing 1 both sides, the U-shaped flashboard assembly 3 being arranged in blowout preventer for sucker rod housing 1, is arranged on sucker rod
The top connection 4 of preventer housing 1 upper end, is arranged on the lower contact 5 of blowout preventer for sucker rod housing 1 lower end, runs through and be arranged on oil pumping
Sucker rod passage 6 in bar preventer housing 1, top connection 4 and lower contact 5, is arranged with and its phase interworking in described top connection 4
The top nut pressure cap 7 closed, is provided with the upper conical centering guide channel cooperated with sucker rod in described top nut pressure cap 7
8, the top nut pressure cap 7 in described upper conical centering guide channel 8 is provided with wearing layer 9, described lower contact 5 is overlapped
It is provided with the lower nut pressure cap 10 cooperated with it, is provided with in described lower nut pressure cap 10 under cooperating with sucker rod
Taper centering guide channel 11, the lower nut pressure cap 10 in described inferior pyramidal centering guide channel 11 is provided with lower wearing layer
12, in the blowout preventer for sucker rod housing 1 of described U-shaped flashboard assembly 3 lower end, it is provided with the interface channel 13 being interconnected and lets out
Pressure passageway 14, the blowout preventer for sucker rod housing 1 between described interface channel 13 and pressure release passage 14 is provided with relief valve 15,
Described interface channel 13 is interconnected with the sucker rod passage 6 of U-shaped flashboard assembly 3 lower end, in the lower end of sucker rod passage 6 and well
Mutually
Connection, is interconnected outside pressure release passage 14 and well.
Above-mentioned multifunctional pumping rod preventer is when sucker rod realizes centering, and sucker rod inserts from top nut pressure cap 8, passes through
The sucker rod passage 7 in top connection 5, housing 1 and lower contact 6 is sequentially passed through, under arrival after the centering of upper conical centering guide channel 9
In nut pressure cap 11, in lower nut pressure cap 11 after inferior pyramidal centering guide channel 12 centering derive preventer.
Above-mentioned multifunctional pumping rod preventer is when carrying out pressure release, and the most U-shaped flashboard assembly 3 is closed, and borehole pressure will
When meeting or exceeding the rated pressure of preventer, opening relief valve 15, the partial pressure in well enters pressure release from interface channel 13
Passage 14 thus derive outside well, alleviate the pressure in well, it is ensured that borehole pressure is less than the rated pressure of preventer.
Above-mentioned multifunctional pumping rod preventer, is solved by upper conical centering guide channel and inferior pyramidal centering guide channel
The centering problem of sucker rod, arranges wearing layer simultaneously in upper conical centering guide channel and inferior pyramidal centering guide channel and increases
Add wear-resisting intensity, anti-bias, abrasion resistant effect good, it is possible to effectively to prevent sucker rod from damaging preventer when stretching into and extract out preventer
Internal shutter, improves the service life of preventer, it addition, install relief valve below ram block, reaches at borehole pressure
Can carry out pressure release before the rated pressure of preventer in advance, eliminate blowout hidden danger, safe and reliable, using effect is good.
