The specific embodiment
Reach embodiment in conjunction with the accompanying drawings the utility model is prevented that the device of petroleum oil and the corrosion of sleeve pipe external screw thread is illustrated.
The utility model prevents that the structure of the device of petroleum oil and the corrosion of sleeve pipe external screw thread from including interconnective successively jet ring 1, car body 2, base plate 3.Described jet ring 1 is a hollow and annular body, evenly is provided with a plurality of through hole C on this ring bodies, and its diameter is 1.5mm-2.5mm.The perforate direction of each through hole C all is the acute angle angle with the center line of jet ring 1, and general the grasp is advisable at 0-60 °.Shown in Fig. 3 (a) and (b) and Fig. 4 (a) and (b), be provided with the through hole that is communicated with described hollow and annular body in a side of jet ring 1, on the periphery of the jet ring 1 of described through hole both sides, be respectively equipped with gudgeon 1-3.Shown in Fig. 3 (a) and (b), (c), described car body 2 includes gas circuit contiguous block 2-1, be fixed on wheel 2-2 on the car body 2, support the supporter 2-3 of jet ring 1 and push down the pressing plate 2-4 of jet ring 1.
Gudgeon 1-3 on the described jet ring 1 is fixed on pressing plate 2-4 on the supporter 2-3 by the pressing plate 2-4 on the car body 2, and the air parcel 1-4 on the described jet ring 1 is connected with gas circuit contiguous block 2-1 on the car body 2.
Actual conditions according to the scene, adopted commonplace medium---compressed air, finish the work that dries up, how to consider at short notice the adhesive force that promptly will overcome the external screw thread raffinate that dries up with very big external force with the external screw thread raffinate to the external screw thread raffinate.According to the mechanics formula of F=P*Q, adopt the gas jet principle, (flow velocity of unit interval is strengthened Q,, make F greater than adhesive force, thereby finish the work that dries up by increasing Q at each Φ C the external screw thread raffinate to increase F.Extraneous compressed air has certain angle A ° ring-type pore φ C to be ejected on the sleeve pipe external screw thread through the astragal on the jet ring, dries up the emulsion raffinate that adheres on it.
According to the layout of sleeve pipe product and production line, development one cover sets up the device of jet ring, finishes the work that dries up of external screw thread raffinate.The technical solution adopted in the utility model provides a kind of device (seeing accompanying drawing 1) that prevents the corrosion of petroleum casing pipe external screw thread.This device comprises: jet ring 1, car body 2, base plate 3 three parts.Wherein the jet ring is connected together with car body by bolt, according to the external diameter difference of steel pipe, and the jet ring 1 of replaceable different size.The effect of car body 2 is by the wheel 2-2 on the artificial promotion car body 2, moves back and forth at base plate 3 upper edge steel pipe axis directions.Car body 2 (seeing accompanying drawing 2) is made up of gas circuit contiguous block 2-1, wheel 2-2, supporter 2-3, pressing plate 2-4.The effect of gas circuit contiguous block 2-1 is that the compressed air with the external world is sent in the jet ring 1, and it is connected with air parcel 1-4 on the jet ring 1 (seeing accompanying drawing 3).The effect of wheel 2-2 is to finish the walking of rolling, and the effect of supporter 2-3 is that the jet ring is supported, and the effect of pressing plate 2-4 is the gudgeon 1-3 that pushes down on the jet ring 1, and jet ring 1 is fixed on the supporter 2-3.Ring 1-2 on the jet ring 1 (seeing accompanying drawing 3) considers mechanical processing technique and does.The core position of this covering device is a jet ring 1, according to the different size of sleeve pipe, has designed the jet ring of different size, and is basic identical with the power that guarantees to blow to thread surface, thus drying up the steel pipe external screw thread raffinate of different size.Jet ring body, as the scope at ° angle of A among Fig. 4 according to the scope of the different angles of thread with A ° of requirement at 0--60.The scope of Φ C is 1.5mm-2.5mm.
The device that prevents the corrosion of petroleum casing pipe external screw thread that processing back external screw thread sleeve pipe 4 to be dried up is made up of jet ring 1, car body 2, base plate 3 in position as shown in Figure 5 dries up processing emulsion residual on the rear thread.The core component of this device is a jet ring 1.Jet ring 1 and car body 2 are connected together by bolt, and when work, they move in base plate 3 upper edge tube axis directions under artificial push-and-pull, finish the work that dries up of full stand of thread.In addition, drying up employed medium is compressed air, extraneous compressed air is connected on the car body by the road, gas circuit contiguous block 2-1 on car body 2 enters in the jet ring 1, compressed air has the aperture C of certain angle at last through a plurality of and tube axis direction on the jet ring 1, be ejected into the sleeve pipe external threaded surface, finish the work of drying up.
On the mode of fixing jet ring, according to the practical layout of production line, can adopt the jet ring hung and move or the fixing mode that moves in plane, adapt to the requirement of production line.On control mode, can adopt automatic, semi-automatic or manual mode.What the utility model adopted is the fixing mode that moves in manual plane.
The fixing mode that moves in the manual plane that the utility model adopted is to move having the suspension of jet loop device, the jet ring can be suspended on the cantilever, by finishing the work of drying up along steel shaft to the moving jet ring.On control mode,, jet ring or car body can be driven with cylinder body or motor, increase several induced signals again and work out simple control program if adopt automated manner, chain with the device program that use at the scene, can finish automatic control.If chain the removing of adopting semi-automatic mode to control in just will controlling automatically can be realized.
