Abstract
The utility model relates to a packing sealing device for a washing pipe of oil rig one end of which is connected with a flange and the other end of which is connected with a union, which is provided with a washing pipe (1). A slurry packing (3) is sealed and arranged at one end of the washing pipe (1) by an upper packing box (2) and all are fixed together into a whole body with an upper cover by a bolt (4); the slurry packing (3) is sealed and arranged at the other end of the washing pipe (1) by a lower packing box (9) and all are fixed together into a whole body with a central pipe by the union (10) in which ladder-shaped screw threads are arranged, and the whole body rotates along with the rotation of the central pipe. Compared with the prior art, the packing sealing device for a washing pipe of the oil rig designed by the utility model is easier to be disassembled and replaced when the phenomenon of heavy wear or damage occurs, thus shortening the replacing time of the sealing packing and improving the repairing efficiency. When the packing sealing device needs replacing, the packing sealing device can shorten the time for disassembly and replacement; therefore the operation is convenient.
Description
Technical field
The utility model relates to a kind of oil-well rig water tap of oil drilling equipment kind washing pipe packing_seal device.
Background technology
The water tap washing pipe is the vitals of sealed high pressure mud with the packing_seal device, the floating punch tubular type packing unit of domestic petroleum rig water tap employing at present, pass through last with union, following packing box is connected with central tube with gooseneck, when needing to change when the wearing and tearing of washing pipe and packing, water tap need be holded up and put surely, in the hammering, following packing pressure cap (being union), unclamp when concordant with washing pipe, can go out packing unit from support one layback behind the double swerve, then washing pipe is pulled out the component of changing serious wear again from the packing box upper end, this device has obtained extensive use because of the localized mode blocking.But according to its dismounting operating mode, its unloading process is not optimized, because being union, its upper and lower side connects, dismounting is with regard to difficult operation when the hammering space on top is spacious inadequately, and the connected mode in reason ninth of the ten Heavenly Stems makes washing pipe length lengthening, cause sealing device weight big, operation is difficult to realize during single replacing packing_seal spare, also causes the excessive height of whole water tap simultaneously.So the bottom that the hammering space is enough still connects with union, and top adopts flange to connect, there is spanner space demounting bolt just can satisfy the requirement of changing seal as long as that is to say top, do so not only and can reduce washing pipe packing_seal installation weight effectively, and can directly the packing_seal device just be pulled out packing unit from support one side, thereby alleviated the dismounting difficulty, shortened washing pipe and changed the time.This practical long problem of washing pipe dismounting and change time that solved effectively.
Summary of the invention
The utility model purpose is a kind of oil-well rig water tap washing pipe packing_seal device of design, changes the time to reduce sealed packing, improves maintenance efficiency.
Specifically, a kind of oil-well rig water tap washing pipe packing_seal device has a washing pipe (1), and it is to use packing box (2) at washing pipe (1) one end to be sealed and installed with mud packing (3) and to be fixed as one by bolt (4) and loam cake together; Be sealed and installed with mud packing (3) with packing box (9) down and the union (10) by built-in trapezoidal thread and central tube connect as one with the rotation of central tube and rotate together at the other end of washing pipe (1).
Mud packing (3) by spacer ring (6), go up grommet (7) and be sealed between packing box (2) and the washing pipe (1), and will go up packing box (2) and last grommet (7) connects as one with steady pin (5), by bolt they and loam cake are fixed together again.
Mud packing (3) is fixed on down in the packing box (9) by following grommet (8) and the union (10) by built-in trapezoidal thread and central tube connect as one with the rotation of central tube and rotate together.
The utility model compared with the prior art, an end of design be flange to connect an end be that the washing pipe that union connects is easier to dismounting and change with the packing_seal device in serious wear or after the phenomenon of damage is arranged, reduce the time that sealed packing is changed, improve maintenance efficiency.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment
The form of structure of the utility model sealed packing device mainly as shown in drawings this packing_seal device by washing pipe (1), go up packing box (2), mud packing (3), bolt (4), steady pin (5), spacer ring (6), go up grommet (7), down grommet (8), the union (10) etc. of packing box (9), built-in trapezoidal thread is formed down.The utility model is divided into two parts, and the upper end is made up of last packing box (2), mud packing (3), steady pin (5), spacer ring (6), last grommet (7) etc., by bolt (4) they and loam cake is fixed together after fitting together again; The lower end is by grommet (8), mud packing (3), following packing box (9) etc. are formed down, after fitting together again the union (10) by built-in trapezoidal thread connect as one with central tube, its concrete unloading process is: the union of the built-in trapezoidal thread of hammering (10), unclamp the back and promote it until flushing with washing pipe (1) lower end, the upper end is unclamped bolt with spanner and is pulled down, and can go out the washing pipe assembly from a thruster.So both satisfied the whole requirement that changes, and can not increase loam cake because of the upper end does not need to reserve the hammering space again, and the connected mode of bolt reduces the loam cake height than the connected mode compactness of union.In addition, be provided with lubricating cup, can make things convenient for the lubricating maintenance of packing at the A place.
