The specific embodiment
Should comprise joint I 1 and joint II 2 for the snap joint of gas drilling.Joint I 1 consists of fittings body A3, safety valve 4, slip valve gap 5, handle 6, restoring spring 7, connecting bolt 8, on safety valve 4, by pin 9, be set with fittings body A3, on fittings body A3, be fixed with handle 6, between safety valve 4 and fittings body A3, restoring spring 7 is housed, on safety valve 4 inwalls, by restoring spring 7, slip valve gap 5 is housed.
The middle part of safety valve 4 is provided with trilobal cross cone valve 10, and the middle part on slip valve gap 5 is provided with valve opening 11, and slip valve gap 5 is slidably connected by valve opening 11 and trilobal cross cone valve 10.On the fittings body A3 termination inwall of slip valve gap 5 one sides, be provided with connecting bolt 8, for being connected of fittings body B13; Between slip valve gap 5 and safety valve 4, sealing ring 12 is housed.
Joint II 2 consists of fittings body B13, back-up ring 14 and cone valve 15, and on back-up ring 14, screw thread is provided with fittings body B13, in back-up ring 14, by valve seat 16 and back-moving spring 17, is movably installed with cone valve 15.Back-up ring 14 inside are provided with taper valve opening 18, and back-up ring 14 is flexibly connected with cone valve 15 by taper valve opening 18.
Joint I 1 is inserted and to be arranged in the fittings body B13 of joint II 2 by fittings body A3, being fixedly connected each other of back-up ring 14 external screw threads in the connecting bolt 8 of joint I 1 by fittings body A3 and fittings body B13; On the circumference of trilobal cross cone valve 10 and cone valve 15, be separately installed with sealing ring 12(referring to accompanying drawing 1).
In the time of should using for the snap joint of gas drilling, first joint I 1 and joint II 2 are installed in respectively to gas drilling control manifold and gas drilling continuous circulation pipe nipple two ends.During work, joint I 1 is inserted into by fittings body A3 in the fittings body B13 of joint II 2, by rotary handle 6, makes the connecting bolt 8 of fittings body A3 and back-up ring 14 external screw threads in fittings body B13 mutually coincide and tighten, thereby reaches the object of quick connection.In this course, the back-up ring 14 of joint II 2 contacts with the slip valve gap 5 of joint I 1, the increasing of tightening stroke along with the connecting bolt 8 of fittings body A3 and back-up ring 14 external screw threads in fittings body B13, trilobal cross cone valve 10 is laminating shape with cone valve 15, and slip valve gap 5 is progressively compressed and retreats by back-up ring 14, thereby trilobal cross cone valve 10 is progressively exited in valve opening 11, valve opening 11 is and opens shape (referring to accompanying drawing 2).
In the course of work, pressed gas in joint I 1 is entered in joint II 2 by valve opening 11, and cone valve 15 is formed to compressing, when the oppressive force to cone valve 15 of pressed gas is greater than the elastic force of back-moving spring 17, cone valve 15 is forced to exit in taper valve opening 18, make taper valve opening 18 be unlatching shape, thereby reach the object (referring to accompanying drawing 3) of gas transport.
In the time of should disconnecting for the snap joint of gas drilling, under the effect of restoring spring 7 and back-moving spring 17, slip valve gap 5 and cone valve 15 playback respectively, joint I 1 and joint II 2 form respectively self-closing sealing state, thereby reach control, there is back flow of gas, and Leakage Gas cause waste, even can initiation fire or the problem of explosion accident.
Should be for the snap joint course of work of gas drilling, gas flow is large, and pressure loss is little; And joint I 1 and joint II 2 form respectively self-closing sealing state, therefore greatly reduced potential safety hazard.Be specially adapted between gas drilling control manifold and continuous circulation pipe nipple, carry out being connected fast use.
