Detailed description of the invention
Combine accompanying drawing below and detailed description embodiment of the present utility model is described.
The two circlip type Quick Connect Kit of drilling riser sleeve pipe, comprise female joint 2, male joint 7, demounting bolt 3, jump ring 4, sealing ring 5, location stop pin 6, female joint 2, male joint 7 points is welded in the two ends of sleeve pipe 1, female joint 2 and male joint 7 junction have draw-in groove 9 and 10, jump ring 4 is stuck in draw-in groove 9 and 10, draw-in groove 4 is nonstandard zigzag with the shape of jump ring 9 and 10, female joint 2 and male joint 7 fitting face are equipped with two sealing rings 5, be equipped with between female joint 2 and male joint 7 and locate stop pin 6, female joint 2 is opened and screw, corresponding with the position of draw-in groove 9, demounting bolt 3 withstands on jump ring 4 by screw, draw-in groove 9 and 10 and jump ring 4 are two, female joint draw-in groove 9 for top be inclined-plane, bottom is the groove at right angle, male joint draw-in groove 10 for top be inclined-plane, bottom is the groove of imploded arcs, female joint 2 is interference fit with the fitting face of male joint 7, between be provided with two sealing rings 5, it is 1/3 just right that screwhole position and draw-in groove 9 and 10 are had an appointment, and location anti-rotation cotter way 8 be low-angle toroidal, and locating stop pin 5 is rectangle.
Described jump ring 4, draw-in groove 9 and 10 adopt the non-standard sawtooth of about 3 °/30 °; Groove depth and groove width are than being 1:1-1:3.Described female joint draw-in groove 9 upper inclined surface adopts 15 °, and groove depth is 10mm; Male joint draw-in groove 10 upper inclined surface adopts 18 °, groove depth 19mm; Jump ring 4 A/F is adjusted to 90mm.Described sealing ring 5 is annular butadiene acrylonitrile rubber sealing ring, diameter dimension Φ 10 ~ 14mm.As shown in Figure 4,5.
Described fitting face precision is IT8 level, and maximum fit clearance is 0.285mm, and minimum fit gap is 0.08mm.
Explain the design feature of the present embodiment below in detail: the sealing means continuing to continue to use drilling riser sleeve pipe circlip type fast-assembling linkage, add the diameter dimension of sealing ring 5, Φ 10 ~ 14mm is increased to by original Φ 8 ~ 10mm, after making assembling, sealing surface increases, and is more practically applicable to the drilling engineering compared with territory, deep-sea.By interior linkage end face by machine control accuracy, realize mechanical seal; Twice large scale annular butadiene acrylonitrile rubber sealing ring 5 seals, and increases the sealing of linkage, and the position of two seals circle 5 not only facilitates machining but also can ensure the dual sealing functions when losing efficacy together.Make it use more reliable, more environmental protection, prevents property loss and environment pollution.Specifically see Fig. 1.
Jump ring 4 is key positions of Quick Connect Kit, plays the effect firmly connected.The connectivity robustness of double card spring 4 is better, and jump ring before has in-site installation difficulty, installs the problems such as rear difficult dismounting, the easy slippage of joint face, there is hidden danger.Through our repetition test research, adjust from each side of jump ring 4, as the small sizes such as gradient, camber, groove depth are improved, and add the effective width of jump ring 4, design more reasonably jump ring 4 shape, all can improve native defect, strengthen connectivity robustness, strengthen safety in utilization.Specifically see Fig. 2.The size shape of double card spring 4 more easily loads and unloads, and strengthens its connectivity robustness.There will not be phenomenon of trying to shirk responsibility, the fastness of better assurance device.
During the dismounting of double card spring Quick Connect Kit, more require the one-time-reach-place of demounting bolt 3.When Quick Connect Kit needs dismounting because of a variety of causes, adopt the mode of button top Circlip apparatus on demounting bolt 3 to carry out, demounting bolt before 3 all withstands on jump ring, exists and pushes up or pushed up phenomenon not in place, thus can not carry out quick-detachment smoothly.Demounting bolt 3 hole site of our design has an appointment 1/3 facing to interior linkage face, when ensureing that push up interior linkage face is obstructed when dismantling, be just in time when pushing up correct position, ensure to dismantle linkage smoothly fast, be more adapted to double card spring Quick Connect Kit.Concrete shape is shown in Fig. 2.
Location anti-rotation device be designed to 2 ~ 3, make linkage more firmly, more reliable.See Fig. 3.
The scope of application: being applicable to waterproof casing diameter is Φ 508mm ~ Φ 914mm, wall thickness 12.7mm ~ 45mm.Material is the grade of steels such as DH32, DH36, EH36 and X42 ~ X80.
