5. a using method for quick connector, containing following steps;
Before using quick connector connecting bypass valve and high pressure line, one end of jack non-in female joint need be connected by union or other modes and high pressure line, this connecting portion when operation quick connector without the need to dismounting.
First one end of plug non-in male joint is connected with bypass valve by screw thread, then the plug of male joint is inserted in the jack of female joint, sealing is realized by the sealing ring in jack, and utilize steel ball or the locking of fixture block locking device, realize the rapid abutting joint of bypass valve and high pressure line, after grafting locking, also available anti-loosing device is held drilling rod short circuit body tightly and is prevented connector accidental release; Otherwise after unclamping anti-loosing device and steel ball or fixture block locking device, the plug of male joint can be extracted in the jack of female joint, and male joint is unloaded from bypass valve, realize bypass valve and high pressure line quick separating;
When using ball lock device, first locking sleeve a is pushed away to the direction of Compress Spring a, until the spacing shoulder a on the thrust surface of locking sleeve a and female joint a touches, now the groove of locking sleeve a just in time retreats to the position of mounting hole of steel ball, male joint a is inserted female joint a, steel ball is pushed in groove by male joint a, male joint a inserts in female joint a smoothly, when male joint a circular bead surface a and female joint a circular bead surface c touches, the installing hole just in time centering of male joint a steel ball draw-in groove and steel ball, release locking sleeve a, locking sleeve a is made to promote spring-go position next time at spring a, steel ball pushes in the steel ball draw-in groove of male joint a by the inclined-plane on locking sleeve a inboard wall groove, by male joint a and female joint a secure lock, to disconnect the connection of male joint a and female joint a, only need again to push away locking sleeve a to the direction of Compress Spring a, when thrust surface and spacing shoulder a touch, when groove retreats to the position of mounting hole of steel ball, male joint a and female joint a can depart from smoothly,
When using anti-loosing device, lock pin is first utilized left clip and right clip to be connected as a single entity and to embrace drilling rod short circuit body, then rotational lock nut, clip seat is moved to the direction away from drilling rod short circuit body under the promotion of turnbarrel circular bead surface e, clip holds drilling rod short circuit body gradually tightly, and the side wall surface of the compressive plane a of left clip and the compressive plane b of right clip and drilling rod short circuit body fits tightly.To unclamp clip, only locking nut need be reversed, clip seat is moved to the direction near drilling rod short circuit body under the promotion in locking nut backup face, and clip relaxes gradually, then extracts lock pin, left clip and right clip can smoothly and drilling rod depart from;
When using fixture block locking device, first make the L-type fixture block of female joint b and the L-type draw-in groove centering of male joint b, the plug b of male joint b is inserted in the jack b of female joint b, now L-type fixture block is inserted in L-type draw-in groove simultaneously, L-type fixture block pushing block, makes locking sleeve b slide to the direction of Compress Spring b; Position is limited when L-type fixture block is inserted into, namely when the end face a of L-type fixture block and the spacing shoulder b of male joint b touches, female joint b is rotated relative to male joint b, L-type fixture block and L-type draw-in groove realize engaging, now form locked groove at block correspondence position, locking sleeve b acts on spring-go position next time at spring b, and block is inserted in locked groove, and male joint b and female joint b is firmly locked; Throw off to make male joint b and female joint b, only locking sleeve b need be slided to the direction of Compress Spring b by external force, when block exits locked groove, the relative male joint b of female joint b is reversed, L-type fixture block is removed with L-type draw-in groove and is engaged, now the plug b of male joint b can be extracted in the jack b of female joint b, male joint b and female joint b departs from smoothly.
