The present invention is achieved by the following technical solutions.
Oil drilling top is driven relief valve protection joint and is included protection adapter body, cartridge filter, sealing member 1, dismounting hole, screw, circlip, sealing member 2, backward L-shaped groove, protection adapter body is a tubular, two ends processing has screw thread, endoporus has one section of internal diameter less at mid portion, upwards radially two symmetrical screwed holes are had at this section of internal diameter smaller part, screwed hole is built with screw, protect near adapter body internal diameter smaller part and bottom hole is built with cartridge filter, in protection adapter body, the outside of two symmetrical screwed holes is counterbore, the outer position processing of counterbore has cannelure, groove is built with circlip, cartridge filter is the cylinder that one end is closed, the upper diameter of cartridge filter is bigger, the processing of its periphery top has two backward L-shaped grooves of symmetry, backward L-shaped groove has downwards cannelure, groove is built with sealing member 1, cartridge filter head with on outer lower face surface and bottom even be distributed have through hole.
On the periphery of cartridge filter top processing have symmetry two backward L-shaped grooves, its horizontal component is 90 degree, at the end of horizontal component, have a bit of transfer to upwards vertical.
Having a downward projection of cylinder bottom cartridge filter, the radial position at cylinder has handling hole.
Screw is hexagon socket cap head screw, and head end has processed downwards positive six square grooves, and the head face of cylinder has twice cannelure, and cannelure is built with sealing member 2, and screw interlude is screw thread, and end is the cylindrical section that diameter is less.
4 sealing members 2 are respectively charged in the cannelure of 2 screws, 2 screws are screwed in internal diameter smaller part two symmetrical screwed holes upwards in protection adapter body.
Sealing member 1 is loaded in the cannelure of lower external face of cartridge filter backward L-shaped groove; by dismounting hole, the cylindrical section of two of cartridge filter top outer round surface symmetrical backward L-shaped groove alignment screw ends is pushed in protection adapter body hole from bottom; after shifting the end onto; cartridge filter 90 degree is rotated clockwise by dismounting hole; strain then downward; relief valve protection joint installation is driven on oil drilling top, and method for dismounting is in contrast.
Oil drilling top being driven relief valve protection upper end of joint and top and drives the lower end of relief valve, the upper end of lower end and drilling rod is threaded connection, and slurry channel connection is complete, it is possible to the operation such as carry out normal drilling well, make a trip.
The invention have the advantages that this oil drilling top is driven relief valve protection joint and is integrated, cartridge filter is directly installed in inside protection joint, and simple and compact for structure, good reliability operates with easy to use, highly versatile, it is easy to safeguard.Manufacture and use are with low cost; long service life; suit large area to popularize use; the application of relief valve protection joint is driven on this oil drilling top; avoid the situation being further added by filter connector for filtering mud between safety joint bottom and drilling rod, improve the quality filtering mud, reduce drilling well risk; extend top and drive the service life of relief valve, reduce production cost.

Detailed description of the invention
In conjunction with Figure of description Fig. 1, Fig. 2, the present invention will be further described.
Oil drilling top is driven relief valve protection joint and is included protection adapter body 1, cartridge filter 2, sealing member 13, dismounting hole 4, screw 5, circlip 6, sealing member 27, backward L-shaped groove 8; protection adapter body 1 is a tubular; two ends processing has screw thread; endoporus has one section of internal diameter less at mid portion; upwards radially two symmetrical screwed holes are had at this section of internal diameter smaller part; being counterbore outside this screwed hole, the outer position processing of counterbore has cannelure.The cylinder that cartridge filter 2 is closed for one end, upper diameter is bigger, the processing of its periphery top has two backward L-shaped grooves 8 of symmetry, backward L-shaped groove 8 horizontal component is 90 degree, at the end of horizontal component, have a bit of transfer to upwards vertical, backward L-shaped groove 8 has downwards cannelure, cartridge filter 2 head with on outer lower face surface and bottom even be distributed have through hole, have a downward projection of cylinder bottom cartridge filter 2, the radial position at cylinder has handling hole 4.Screw 5 is hexagon socket cap head screw, and head end has processed downwards positive six square grooves, and the head face of cylinder has twice cannelure, and screw 5 interlude is screw thread, and end is the cylindrical section that diameter is less.
Being respectively charged in the cannelure of 2 screws 5 by 4 sealing members 27, screwed in by 2 screws 5 in protection adapter body 1 in internal diameter smaller part two symmetrical screwed holes upwards, the cylindrical section that screw 5 end diameter is less enters in the hole of protection adapter body 1;2 circlips 6 are loaded in the cannelure at the outside outer position of counterbore of screwed hole of protection adapter body 1.
Sealing member 13 is loaded in the cannelure of cartridge filter 2; by dismounting hole 4, the cylindrical section of two of cartridge filter 2 top outer round surface symmetrical backward L-shaped channel opening alignment screw 5 ends is pushed in protection adapter body 1 hole from bottom; after shifting the end onto; cartridge filter 290 degree is rotated clockwise by dismounting hole 4; strain then downward; relief valve protection joint installation is driven on oil drilling top, and method for dismounting is in contrast.
Oil drilling top is driven relief valve protection upper end of joint and pushes up the lower end driving relief valve, the upper end of lower end and drilling rod is threaded connection, slurry channel connection is complete, open slush pump, mud drives relief valve entrance oil drilling top and drives protection adapter body 1 endoporus the first half of relief valve protection joint from top, it flow to screw 5 and the top of cartridge filter 2, owing to the cannelure of 2 screws 5 is built with 4 sealing members 27, the cannelure of cartridge filter 2 is built with sealing member 13, play closure mud to leak outside and effect from the outside overflow of cartridge filter 2, the top of upwards vertically section is transferred to again owing to the roundlet shell of column of 2 screw being symmetrically installed 5 ends supports 2 backward L-shaped groove 8 horizontal component ends of cartridge filter 2 symmetry, so the position of cartridge filter 2 is fixing, will not be washed away by mud, mud enter cartridge filter 2 internal downwards by its head with on outer lower face surface and the through hole that is distributed of bottom even flow out, it is internal that foreign material stay cartridge filter 2, what flow out is the clean mud through filtering, clean mud flows into protection adapter body 1 endoporus the latter half, flow downwardly into drill pipe bore, normal drilling well can be carried out, the operation such as make a trip.
During trip-out stacks; top is driven the connection screwed apart of relief valve protection joint lower end and drilling rod upper end; by the handling hole 4 radially opened on cylinder downward projection of bottom filter cylinder 2, cartridge filter is unloaded; pour out the foreign material of inside; again through handling hole 4, cartridge filter is installed; connect drilling rod and namely can carry out normal operation, convenient and swift.
