Abstract
Provided is a quick connector falling prevention valve. Pawls of the quick connector falling prevention valve can prevent a quick connector from passing through a valve body from top to bottom, but a cable can freely pass. When a torpedo passes through the valve body from bottom to top, the torpedo can eject the pawls open after abutting against the pawls, the torpedo can smoothly pass through the valve body from bottom to top, and the pawls are closed immediately after the torpedo passes.
Description
Technical field
Patent of the present invention relates to oil field Cut-and-thread fishing field of operation, specifically a kind ofly prevents snap joint from surprisingly to fall the one way valve of well, it is arranged in the hydrophthalmia of drilling tool and plays protection snap joint and surprisingly to fall the effect of well, avoid secondary to salvage.
Background technology
At present, existingly prevent surprisingly the fall means of well of snap joint from being add safety collar in drilling tool water hole, its effect prevents snap joint to fall well, and ensure that torpedo in the head harness of down-hole is by safety collar, but often occur that the endoporus of safety collar is less than the situation of torpedo maximum outside diameter, cause torpedo to cannot get through safety collar, this is that punching fishing institute is unallowed, if do not install safety collar in drilling tool, only ensureing that torpedo passes through, just there is snap joint and surprisingly to fall the risk of well in that.
Summary of the invention
Patent of the present invention cannot normal through the deficiency of safety collar in order to overcome above-mentioned torpedo, provide a kind of prevent unexpected fall the anti-lost valve of snap joint of well, this anti-lost valve can either block the snap joint of the well that surprisingly falls, can ensure that again various torpedoes in the head harness of down-hole are back through anti-lost valve, improve the reasonability of Cut-and-thread fishing operation, safety, reliability.
Patent of the present invention for the technical scheme realizing its technical problem and adopt is: on the annular end face of a metallic cylinder, decile installs 3 or 4 ratchets, be easy to back down ratchet after pushing up ratchet during endoporus when there being torpedo, and can pass through smoothly, automatically closed again by rear ratchet at once, if but there is snap joint to fall down from above, closed ratchet will block it, snap joint is stoped to come off, the accident so both protecting snap joint falls well, torpedo can be allowed again to pass through smoothly, add the safety of operation, reasonability, reliability.
The object of patent of the present invention is: in the Cut-and-thread fishing operation process of oil field, provides more rational, practical, easily, safe and reliable instrument equipment.
The beneficial effect of patent of the present invention is: make Cut-and-thread fishing operation more convenient, safe and reliable, reduces risk.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the anti-lost valve of patent snap joint of the present invention is described further.
Fig. 1 is a of the anti-lost valve of patent snap joint of the present invention, b two states constructional drawing
In Fig. 1, a represents the anti-lost valve of snap joint of nature, 1 main body, 2 ratchets, 3 cable spaces, 4 ratchet rotating shafts, 5 cable channels
B represents ratchet by the anti-lost valve of snap joint during jack-up, 1 main body, 2 ratchets, 3 cable spaces, 4 ratchet rotating shafts, 5 cable channels
Detailed description of the invention
In Fig. 1 in a, 1 main body installs three 2 ratchets, 2 ratchets are fixed by 4 ratchet rotating shafts, three 2 ratchets control to only have cable upper and lowerly to pass through 3 cable spaces under this closure state, and cable can be advanced in 3 cable spaces by 5 cable channels beyond 1 main body, facilitate the anti-lost valve of patent one of the present invention snap joint to be in use arranged in drilling tool water hole and from hydrophthalmia and it is removed.
In Fig. 1 in b, in 1 main body, three 2 ratchets are by the state backed down, that down-hole torpedo is upwards pulled out by cable under this state, back down three 2 ratchets, at this moment 3 cable spaces become large, torpedo just by, torpedo just can by cable-pull, after torpedo passes through, three 2 ratchets are at once just closed, make 3 cable spaces get back to again the nature of the anti-lost valve of snap joint; Cable can upper and lowerly pass through, if the snap joint larger than cable size is fallen down from above, three 2 ratchets be just closed block, thus achieves and prevent snap joint to fall well, can allow again the object that down-hole torpedo passes through.
Claims (3)
1. the anti-lost valve of snap joint, one of its feature is: on the annular end face of a metallic cylinder, be provided with ratchet, blocks snap joint by valve body by ratchet, but cable can freely pass through.
2. the anti-lost valve of snap joint, two of its feature is: when having torpedo from below by after pushing up ratchet during valve body, can back down ratchet, and torpedo can from below upwards smoothly by valve body, and torpedo is at once closed by rear ratchet.
3. the anti-lost valve of snap joint, three of its feature is: on valve body, have cable channel, and cable can advance and release valve body from valve body.
