Description
Technical field
The utility model relates to the well-control equipment that a kind of drilling well well workover is used, and relates in particular to a kind of throttling pressure regulation strainer.
Background technology
Oil drilling is mainly will be transported to well inner screw drilling tool by strainer than weighted mud or clear water by slush pump or pressure car, thereby the hydraulic motor in drive screw rotates the object that reaches drilling well, original filtration device structure only has a kind of flow pressure, can not regulate, because the screw rod of different model has different requirements to flow pressure, in the time changing drilling rod, can not well mate with drilling rod, labour intensity is large, inefficiency.
Utility model content
Technical problem to be solved in the utility model is: the throttling pressure regulation strainer that a kind of controllable flow rate pressure is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: throttling pressure regulation strainer, comprise: inlet union, the filter housing being connected with inlet union, the transition joint being connected with the filter housing other end, the connected with outer casing being connected with the other end of transition joint and the outlet connection being connected with the connected with outer casing other end, in described filter housing, be provided with relief piston, in described relief piston, be provided with chimney filter, on described chimney filter, be evenly provided with some filter openings, outside at described relief piston is fixedly installed tooth bar, described tooth bar cooperatively interacts with the gear being arranged on knob one end, described knob is arranged in described transition joint, 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 utility model adopts is: between described filter housing and relief piston, be provided with the first sealing ring, between described filter housing and transition joint, be provided with the second sealing ring, between described relief piston and chimney filter, be provided with the 3rd sealing ring and the 4th sealing ring, between described knob and transition joint, be provided with the 5th sealing ring, between described transition joint and connected with outer casing, be provided with the 6th sealing ring.
The utility model has the advantages that: above-mentioned throttling pressure regulation strainer, there is throttling, pressure regulation and filtering function simultaneously, can the requirement to flow pressure according to the screw rod of different model, the at any time size of adjust flux pressure, reduce labour intensity, improved operating efficiency.

In figure: 1, inlet union, 2, filter housing, 3, transition joint, 4, connected with outer casing, 5, outlet connection, 6, relief piston, 7, chimney filter, 8, filter opening, 9, tooth bar, 10, knob, 11, gear, 12, handle, 13, the first sealing ring, 14, the second sealing ring, 15, the 3rd sealing ring, 16, the 4th sealing ring, 17, the 5th sealing ring, 18, the 6th sealing ring.
The specific embodiment
Describe in detail particular content of the present utility model below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, throttling pressure regulation strainer, comprise: inlet union 1, the filter housing 2 being connected with inlet union 1, the transition joint 3 being connected with filter housing 2 other ends, the connected with outer casing 4 being connected with the other end of transition joint 3 and the outlet connection 5 being connected with connected with outer casing 4 other ends, in described filter housing 2, be provided with relief piston 6, in described relief piston 6, be provided with chimney filter 7, on described chimney filter 7, be evenly provided with some filter openings 8, be fixedly installed tooth bar 9 in the outside of described relief piston 6, described tooth bar 9 cooperatively interacts with the gear 11 being arranged on knob 10 one end, described knob 10 rotates and is arranged in described transition joint 3, the other end of described knob 10 is connected with handle 12.
As shown in Figure 1 and Figure 2, in this example, in order to reach good sealing effectiveness, between described filter housing 2 and relief piston 6, be provided with the first sealing ring 13, between described filter housing 2 and transition joint 3, be provided with the second sealing ring 14, between described relief piston 6 and chimney filter 7, be provided with the 3rd sealing ring 15 and the 4th sealing ring 16, between described knob 10 and transition joint 3, be provided with the 5th sealing ring 17, between described transition joint 3 and connected with outer casing 4, be provided with the 6th sealing ring 18.
When use, one end of throttling pressure regulation strainer is connected with pressure car, the other end of throttling pressure regulation strainer is connected with helicoid hydraulic motor, pressure car is pressed into filter housing 2 inside by mud from inlet union 1, pull handle 12, handle 12 drives knob 10 to rotate, knob 10 driven gears 11 rotate, because gear 11 and tooth bar 9 are intermeshing, thereby move backward the filter opening 8 exposing gradually on chimney filter 7 with carry-over bar 9 together with relief piston 6, mud is filtered and is entered in chimney filter 7 by filter opening 8, the filter opening 8 now exposing more multilist shows that the mud that can filter is just more, flow pressure in chimney filter 7 is also just larger, until all filter openings 8 expose, arrive full open position.
Above-mentioned throttling pressure regulation strainer has throttling, pressure regulation and filtering function simultaneously, can the requirement to flow pressure according to the screw rod of different model, and the size of adjust flux pressure, has reduced labour intensity at any time, has improved operating efficiency.
