Abstract
The utility model relates to a flexible pipe connector, belonging to pipe conveying fluid connector technical field, which deals with the problem of low bearing pressure of the prior flexible pipe connector. The utility model is characterized in that the utility model comprises a joint body matched with the flexible pipe; a sealing ring is arranged at the lateral side of the joint body; a connecting body and a pipe clip are sleeved on the outer wall of the joint body; an extending claw and a connecting sliding groove matched with the shape of the claw are arranged at the outer end of the connecting body; a tendon is arranged at the outer wall of the inner side of the connecting body; the middle spacing of the connecting sliding groove is greater than the spacing of the two sides. The utility model has the advantages of convenient installing-uninstalling operation, reliable working and withstanding pressure of more than or equal to 2.4MPa, and being used for oil transportation (gasoline, kerosene, diesel, oil and other categories).
Description
Technical field
The utility model relates to a kind of hose coupling, particularly a kind of be mainly used between flexible pipe and the flexible pipe and flexible pipe and other transfusion apparatus pipeline between the hose coupling that is connected.Belong to indusion tube joint technical field.
Background technique
At present, the domestic hose coupling that is used for the oils conveying is made of male coupling 3, cloudy end connector 6, eccentric handle 4 and seal ring 5, during use, flexible pipe 1 is set on male coupling 3 and the cloudy end connector 6, generally adopts galvanized wire 2 fixing.Its deficiency one is that the structural type of this hose coupling and intensity can not meet the demands when carrying liquid to bear elevated pressures (working pressure is greater than 1MPa); The 2nd, tie up the sealing that realizes between joint 3,6 and the sebific duct 1 by galvanized wire 2 between joint 3,6 and the sebific duct 1, galvanized wire 2 is tied up and is connected trouble, and the power of tying up is not easy to grasp.Tie up tension, galvanized wire 2 easily snaps, and also can damage flexible pipe.When working pressure during greater than 1MPa, galvanized wire 2 reduction in strength also produce fracture, cause leak of liquid; The 3rd, because joint 3,6 inside nominal diameters greater than 100mm, when pulling two handles 4, are operated relatively difficulty.
Summary of the invention
The purpose of this utility model provides a kind of dress at above-mentioned deficiency exactly, it is easy to operate to tear open, reliable operation, withstand voltage higher a kind of hose coupling.
Technical solution of the present utility model is: a kind of hose coupling, comprise a fittings body that cooperates with flexible pipe, and the side of this fittings body is provided with seal ring, and wall is set with connecting body and pipe clamp outward.The outboard end of connecting body be provided with the claw that stretches out with the chute that is connected of claw form fit, inboard outer wall is provided with muscle.Connect the spacing of the stage casing spacing of chute greater than its both sides.
Fittings body end described in the utility model technical solution can be provided with the groove that the inner ring side is an arc, and this groove inboard is provided with annular groove; The shape of seal ring matches with this groove and annular groove thereof, and coats its inner ring along face.
Pipe clamp described in the utility model technical solution can be formed by connecting by screw, and its inwall is provided with the pipe clamp muscle that end face is a conical surface.
The utility model is owing to adopt pipe clamp, fittings body, connecting body and seal ring etc. constitute hose coupling, during assembling, seal ring is packed in the groove of fittings body arc, fittings body one end is packed in the endoporus of flexible pipe, and flexible pipe is fixed on the fittings body by pipe clamp, thereby when using, only need the claw of connecting body is extend in the connecting body connection chute of another hose coupling, and the body that is rotatably connected is in claw to connect the inner end of chute, but the so just seal ring of pressed joint end of body, realize the sealing of end face between fittings body, and can bear higher pressure, finally realize being connected between flexible pipe and the flexible pipe.During dismounting, only need claw is withdrawed from from connecting in the chute, make between the connecting body and separate by the opposite direction body that is rotatably connected.Because the connection chute stage casing spacing on the connecting body can make between connecting body and the connecting body and produce self-locking greater than the spacing of both sides, prevent between connecting body and the connecting body loosening slippage when bearing high pressure and cause leak of liquid.Because the connecting body outer wall is axially arranged with equally distributed muscle, can increase the intensity of connecting body, the clamping of the special tool of the body of also being convenient to be rotatably connected, whether the muscle by two connecting bodys aligns and can judge also whether two connecting bodys are in the state of locking simultaneously.Owing to adopt fixedly flexible pipe of pipe clamp, the sealing reliability that is connected between flexible pipe and the hose coupling is improved greatly.The utility model compared with prior art has dress, it is easy to operate to tear open, reliable operation, and the characteristics of withstand voltage 〉=2.4Mpa are mainly used in the conveying of oils (gasoline, kerosene, diesel oil, machine oil etc.).Also can be used for the conveying of water and other non-corrosive liquid.Extensive use in occasions such as oil depot, gas station, oil carrier, naval vessels, oil carrier, field oil depot outer tube.

Embodiment
Extremely shown in Figure 5 as Fig. 2.Fittings body 10 is a tubulose, and its outer wall is provided with pipe clamp groove 11 and circlip groove 9, and connecting body 13 is sleeved on the outside of fittings body 10, and is fixing by axle-steel silk back-up ring 15, but opposing tabs body 10 rotates.Three claws 20 are symmetrically distributed, and extend laterally.The end of connecting body 13 is provided with and connects chute 12, and the edge of chute 12 is provided with breach, is convenient to claw 20 and enters.Chute 12 matches with claw 20.Connect the spacing of the stage casing spacing of chute 12 greater than both sides.Muscle 14 is evenly distributed on the connecting body 13 inboard outer walls.Pipe clamp 17 is made of three lobe pipe clamps and socket cap screw 18 and nut 19.The inwall of pipe clamp 17 is provided with three pipe clamp muscle 16, and is corresponding with the pipe clamp groove 11 of fittings body 10.The end face of pipe clamp muscle 16 is a conical surface 24, like this, can make its with fittings body 10 between form point and contact, flexible pipe 21 can be fixedly secured on fittings body 10, and sealability further improves.Fittings body 10 exterior edge faces are provided with groove 8, and groove 8 sides are arc, and groove 8 inboards are provided with annular groove.Seal ring 7 inner side surfaces are and groove 8 corresponding cambered surfaces 22, and its snap ring 23 is bumped into the annular groove of groove 8 inboards, coat its inner ring along face, can guarantee excellent sealing performance like this.
