Abstract
The utility model relates to a claw-style flaring spinning fast joint which realizes a joint of the connection of a central spindle and flaring pipe fittings. A casing which is in detachable connection is arranged on the joint of the central spindle; a cutting sleeve is sheathed outside the casing which is displaced by the push of a cutting sleeve spring and fixed by locating screws; a plurality of claws which are hooked are arranged between the casing and the cutting sleeve; the claws can be opened and closed. The clasp or the release of the flaring pipe fittings is realized along the axial displacement of an L-shaped groove by the claws through the cutting sleeve; the lock or the stop of the connection is realized by the radial rotation along the L-shaped groove; the flaring pipe fittings are inserted by the opening and the closing of the claws, which is realized by a valve core arranged between the joint of the central spindle and the casing; the valve core is pushed by a valve core spring. The utility model has the advantages that the utility model avoids the defect of easily ejecting under high pressure, and meanwhile, the surface of the pipe fittings can not be damaged; the utility model has the advantages of safe use, simple and convenient operation, and rapid connection; the utility model can avoid the phenomenon of connection failure under vibrations or misoperation.
Description
Technical field
The utility model relates to a kind of fast connecting joint that the refrigeration industry pipeline vacuumizes, fills refrigeration agent, leak detection, especially a kind of Catche Flared Quick-Acting Joint.
Background technique
Carrying out pipeline at refrigeration industry vacuumizes or fills in refrigeration agent or the leak detection operation, must rely on fast connecting joint carries out indoor, outer machine pipeline connects, particularly to be link with the flared pipe fitting to leak detection pressure higher and when requiring not damage the connection occasion on pipeline surface again, more need a kind of jointing of seizing type to realize connecting fast purpose, and the existing monitoring tap that is used for the flared pipe fitting connection, be to realize connecting by the step surface of steel ball buckle flared pipe fitting, because steel ball and flared pipe fitting are to contact, easily eject during high pressure and easily cause the pipe fitting surface failure, dangerous.
Summary of the invention
Goal of the invention of the present utility model all provides a kind of safe in utilization, Catche Flared Quick-Acting Joint of not damaging the pipe fitting surface in the defective that overcomes prior art.
Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of Catche Flared Quick-Acting Joint, it comprises mandrel joint and connected flared pipe fitting, the mandrel joint is provided with the housing of detachable connection, it is characterized in that described housing is set with by the displacement of cutting ferrule spring push and by the fixing cutting ferrule of positioning screwn outward; But be provided with several claws that linked opening and closing between described housing and the cutting ferrule, this claw is realized the obvolvent of flared pipe fitting by cutting ferrule axial displacement or is loosened; Be provided with between described mandrel joint and the housing realize that claw is open can be by the valve core spring pushing tow along the spool of housing endoporus displacement.
Described cutting ferrule is provided with " L " type groove of realizing axial displacement and rotating locking.
Be provided with two pass " O " RunddichtringO between described mandrel joint and the flared pipe fitting.
Compared with prior art, but the utility model adopts obvolvent or loosens the claw of flared pipe fitting and spool pushing tow claw opens and is convenient to the technological scheme that flared pipe fitting inserts, overcome the defective that steel ball card button system point contact high pressure easily ejects, do not damage simultaneously the pipe fitting surface, safe in utilization, easy and simple to handle, connect fast, can also avoid connecting failure phenomenon under vibrations or the misoperation situation by locking.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Fig. 2 is the worm's eye view of Fig. 1.
Embodiment
To the utility model be described in further detail again with the accompanying drawing embodiment who provides below.
Shown in Fig. 1～2, Catche Flared Quick-Acting Joint is a jointing of realizing mandrel joint 1 and flared pipe fitting 9, is provided with double sealing circle 8 between the two, guarantees to connect sealing.Stair-stepping mandrel joint 1 is provided with the housing 2 of the detachable connection of screw thread, housing is set with the cutting ferrule 6 by the 4 pushing tow displacements of cutting ferrule spring outward, " L " type groove 10 is arranged on the cutting ferrule, realize the fixing of cutting ferrule and housing by positioning screwn 11, " L " type groove makes cutting ferrule displacement vertically realize the obvolvent of flared pipe fitting 9 or loosens, and reaches the locking cutting ferrule and prevents to connect and lost efficacy by radially rotating simultaneously.
But be provided with the claw 7 of 6 circumference uniform distributions that linked opening and closing between described housing 1 and the cutting ferrule 6, this claw is to the obvolvent of flared pipe fitting or to loosen be to realize flared pipe fitting is clamped the key that whether connects, housing outer surface is processed with annular groove, the boss shoulder on annular groove limit links claw and does not leave, claw back indent, can integral body shape the back and be divided into 6, be arranged on the circumferential surface of housing with the line cutting.Claw opens and flared pipe fitting could be inserted, realize claw open be spool (5), spool is located between mandrel joint and the housing, by the pushing tow of valve core spring 3 spool is realized along the displacement of housing endoporus.
Before flared pipe fitting 9 does not connect, cutting ferrule 6 axial displacement left, the farthest right position that this moment, positioning screwn 11 entered " L " type groove 10, the obvolvent face of cutting ferrule 6 ends moves to aligning claw 7 indent backs and is limited displacement, spool 5 is under valve core spring 3 thrusting actions, back down claw to suitable deployed position, guarantee that connected flared pipe fitting 9 inserts smoothly, promote spool when inserting and leave claw left, the valve core spring compression, this moment, claw was in free state, and cutting ferrule 6 eliminated the restriction just under the effect of cutting ferrule spring 4, move right, positioning screwn 11 enters the intersection location of " L " type groove 10, and cutting ferrule 6 obvolvent faces make the stepped portions of claw chucking flared pipe fitting 9 with regard to obvolvent on claw 7, promptly is in the coupled condition of Fig. 1.Allow positioning screwn 11 enter the radially position of " L " type groove 10 in order to prevent that vibrations or misoperation from causing continuous damage, cutting ferrule 6 can be rotated, cutting ferrule does not eject even also can guarantee to connect under vibrations or misoperation situation just by locking.
When needs broke away from connection, backward rotation cutting ferrule 6 was at first removed locking, promotes cutting ferrule then left, and flared pipe fitting just breaks away from connection under the spool pushing tow.
