Description
Technical field
The present invention relates to the well-control equipment that a kind of drilling well well workover is used, relate in particular to a kind of throttling and adjustPress filtration device.
Background technology
Oil drilling is mainly will pass through than weighted mud or clear water by slush pump or pressure carFilter is transported to well inner screw drilling tool, thereby the rotation of the hydraulic motor in drive screw reaches brillThe object of well, original filtration device structure only has a kind of flow pressure, can not regulate, due toThe screw rod of different model has different requirements to flow pressure, can not be fine in the time changing drilling rodMate with drilling rod, labour intensity is large, inefficiency.
Summary of the invention
Technical problem to be solved by this invention is: a kind of throttling of controllable flow rate pressure is providedPressure regulation filter.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: throttling pressure regulationFilter, comprising: inlet union, the filter housing being connected with inlet union, with filterThe transition joint that the shell other end is connected, be connected with the other end of transition joint be connected outsideShell and the outlet connection being connected with the connected with outer casing other end arrange in described filter housingThere is relief piston, in described relief piston, be provided with chimney filter, on described chimney filter, evenly arrangeHave some filter openings, be fixedly installed tooth bar in the outside of described relief piston, described tooth bar with establishThe gear of putting on knob one end cooperatively interacts, and described knob is arranged on described transition jointUpper, the other end of described knob is connected with handle.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adoptsBe: between described filter housing and relief piston, be provided with the first sealing ring, described mistakeBetween filter shell and transition joint, be provided with the second sealing ring, described relief piston and chimney filterBetween be provided with the 3rd sealing ring and the 4th sealing ring, between described knob and transition joint, establishBe equipped with the 5th sealing ring, between described transition joint and connected with outer casing, be provided with the 6th sealingCircle.
Advantage of the present invention is: above-mentioned throttling pressure regulation filter, have simultaneously throttling, pressure regulation andFiltering function, can the requirement to flow pressure according to the screw rod of different model, at any time adjusting streamThe size of piezometric power, has reduced labour intensity, has improved operating efficiency.

Detailed description of the invention
Describe in detail particular content of the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, throttling pressure regulation filter, comprising: inlet union 1,The filter housing 2 being connected with inlet union 1, is connected with filter housing 2 other endsTransition joint 3, the connected with outer casing 4 being connected with the other end of transition joint 3 and be connectedThe outlet connection 5 that shell 4 other ends are connected is provided with tune in described filter housing 2Press piston 6, in described relief piston 6, be provided with chimney filter 7, even on described chimney filter 7Be provided with some filter openings 8, be fixedly installed tooth bar 9 in the outside of described relief piston 6, instituteState tooth bar 9 and cooperatively interact with the gear 11 being arranged on knob 10 one end, described knob 10Rotation is arranged in described transition joint 3, and the other end of described knob 10 is connected with handle 12Connect.
As shown in Figure 1 and Figure 2, in this example, in order to reach good sealing effectiveness, instituteBetween the filter housing 2 of stating and relief piston 6, be provided with the first sealing ring 13, describedBetween filter housing 2 and transition joint 3, be provided with the second sealing ring 14, described pressure regulationBetween piston 6 and chimney filter 7, be provided with the 3rd sealing ring 15 and the 4th sealing ring 16, describedBetween knob 10 and transition joint 3, be provided with the 5th sealing ring 17, described transition joint 3And between connected with outer casing 4, be provided with the 6th sealing ring 18.
When use, one end of throttling pressure regulation filter is connected with pressure car, and throttling pressure regulation is filteredThe other end of device is connected with helicoid hydraulic motor, and pressure car was pressed into mud from inlet union 1Filter shell 2 inside, pull handle 12, and handle 12 drives knob 10 to rotate, knob 10Driven gear 11 rotates, because gear 11 and tooth bar 9 are intermeshing, thus band carry-over bar 9Move backward the filter opening 8 exposing gradually on chimney filter 7 together with relief piston 6, mud is by filterHole 8 is filtered and is entered in chimney filter 7, and the filter opening 8 now exposing more multilist shows the mud that can filterJust more, the flow pressure in chimney filter 7 is also just larger, until all filter openings 8 expose, arrivesFull open position.
Above-mentioned throttling pressure regulation filter has throttling, pressure regulation and filtering function, Ke Yigen simultaneouslyRequirement according to the screw rod of different model to flow pressure, the size of adjust flux pressure, falls at any timeLow labour intensity, has improved operating efficiency.
