Abstract
The utility model relates to a quick-connection joint for a casing-pipe used in an offshore oil and gas well. The utility model is composed of a male joint, a female joint, a clamping ring, a sealing ring, a rotating preventing pin, and twelve unlocking screws. The utility model uses an inserting and automatic locking structure. As long as the corresponding insertion between the male joint and the female joint is realized, firm joining can be realized without the requirement of rotation. When the utility model is welded at both ends of a casing-pipe, the connection of the casing-pipe is both fast and safe. The utility model is very suitable for specific requirements in the aspects of time and safety in the operation of offshore drilling. The utility model has the advantages of reasonable design, simple structure, easy and simply implemented operation, favorable performance of structure sealing, and capability of replacing imported products.
Description
Technical field the utility model belongs to the sleeve pipe jointing in the offshore drilling engineering, particularly offshore oil and gas casing fast connecting joint.
Background technology is present, and it generally is to adopt to be threaded or to weld that sleeve pipe in the offshore drilling engineering connects, and the operating time is long, particularly to major diameter sleeve pipe or the big more difficult operation of equipment of weight, connects quick, safety in order to make sleeve pipe, needs develop fast connecting joint.For example patent 96223035.9 oil well pipe thread joints, patent 96223036.7 oil well pipe thread joints, patent 96222992.X oil well pipe thread joint or the like also fail to address the above problem.
The technology contents the purpose of this utility model provides a kind of offshore oil and gas casing fast connecting joint, adopts and inserts and the automatic locking structure, only needs the male and female joint to insert relatively, need not rotate, and gets final product firm engagement.Be welded in the sleeve pipe two ends with it, make sleeve pipe connect not only quick but also safety, be highly suitable for the specific (special) requirements of Offshore Operation time and secure context.The utility model is made up of male and female joint, jump ring, sealing ring, stop pin and 12 release screws, female joint (1), male joint (2) are welded in the sleeve pipe two ends respectively, female joint (1), male joint (2) fitting face are equipped with two sealing rings (3), the jump ring that spring is made (4) is stuck in the draw-in groove of female joint (1) and male joint (2) cooperation, take the male and female joint that has engaged apart with 12 release screws (6), between female joint (1) and male joint (2), stop pin (5) is housed also.The utility model is reasonable in design, and is simple in structure, and operation is simple, and its sealing structure performance is good, and promotes the use of, but the import substitution product.
Description of drawings Fig. 1 is the utility model structural representation.
The specific embodiment is in the utility model, as shown in Figure 1, except that sealing ring with rubber manufacturing, jump ring with the spring steel manufacturing, other is as male and female joint, stop pin and 12 release screws, all available steel are realized by manufacturing technologies such as forging, machine, heat treatment, phosphatizations.The male and female joint is welded in the sleeve pipe two ends respectively, just can uses after the assay was approved through pressure testing.Using on the platform is plumbness, and female joint is last, and male joint is following, and mutually to after being inserted into the position, jump ring opens automatically the male and female joint is coupled together.If need take the joint that has engaged apart, only need be screwed into 12 release screws jump ring is compressed, the male and female joint just can draw back.Connect quick and safe, take apart also very simple.
