Abstract

The invention provides a quick four-start thread conductor adapter. An internally threaded adapter comprises a four-start thread and a sealing groove, an externally threaded adapter comprises a four-start thread, an upper shoulder and a locking groove, wherein a locking block is mounted in the locking groove and fixed by lock screws. The quick four-start thread conductor adapter adopts a ternary sealing mode, the first seal is an end face seal which is adopted at the joint between the top surface of the internally threaded adapter and the external step surface of the externally threaded adapter, the second seal is a mechanical seal which is adopted on the inner side of the upper part of the thread of the internally threaded adapter and the side of the externally threaded adapter, and the third seal is an O-shaped seal ring seal which is adopted on the inner side of the thread of the internally threaded adapter. The quick four-start thread conductor adapter has the advantages that: the quick four-start thread conductor adapter is quick to mount; the structure is reasonable, the firmness of mounting can be ensured, the sealing effect of the quick four-start thread conductor adapter is good, and the quick four-start thread conductor adapter is safer and firmer; the quick four-start thread conductor adapter can prevent the phenomenon of reverse screwing in the process of construction, thus ensuring safe production and construction.

Description

Four-head spiral duct Quick Connect Kit
Technical field
The present invention relates to a kind of drilling well conduit, especially four-head spiral duct Quick Connect Kit.
Background technique
Along with the development of marine drilling technology, offshore petroleum rig is carried out comprehensively, to the requirement of marine drilling diversification gradually, need quality and efficiency to go forward side by side, existing cover pipe connection speed is slower, reach locking state consuming time longer, and can not be applicable to various marine environments; While, so just had higher requirement to the Security of connection speed, sealing and the use of cover pipe connection because structural damage easily causes life, property loss and environmental pollution in each stage of constructing and using.
Summary of the invention
The object of the invention is provides a kind of four-head spiral duct Quick Connect Kit for fear of above-mentioned deficiency.
Technological scheme of the present invention is: four-head spiral duct Quick Connect Kit, comprise that outside thread connection set and internal thread connection set form, internal thread connection set comprises that four-head screw thread and seal groove form, outside thread connection set comprises four-head screw thread, upper shoulder and locking slot form, wherein locking slot the inside is provided with locking block, and described locking block is fixed by lock screw; Four-head screw thread Quick Connect Kit adopts triple seal mode, one is heavily that internal thread connection set top end and the outer step surface of outside thread connection set contacting point adopt end face seal, double is that internal thread connection set screw thread upper inner face and outside thread connection set side adopt mechanical seal, and triple is that internal thread connection set screw thread inner side adopts the sealing of O RunddichtringO.
Described seal groove is up-narrow and down-wide.
One side of described locking block is also provided with square tooth.
The taper pipe thread joint of described four-head screw thread Quick Connect Kit tapering between 1:8-1:16.
Described taper pipe thread adopts water system thread standard.
Advantage of the present invention is: 1, four-head spiral duct Quick Connect Kit, on-the-spot joint connects the efficiency that has improved at least 4 times, installs faster.
2, rational in infrastructure, the up-narrow and down-wide structural feature of sealing Cao Caiyong, can ensure the soundness while installing, and its good sealing effect is safer firm.
3, locking block is convenient and swift, can after screw thread tightens, further lock pin and box sub, prevents the phenomenon of screw thread back-off in work progress, and construction guarantees safe production.
