Abstract
The utility model relates to a jacket type tube joint. The utility model has the structure that a joint body has a through hole, the inside diameter of the hole is slightly larger than the outside diameter of a connecting tube, the end of the joint body is provided with a stepped hole, a sealing ring and a jacket are arranged in the stepped hole, thread screws outside the stepped hole are connected with a joint cap. A vertical slot is arranged on the jacket, a circular channel is arranged at the root of the circular slot to form a holding jaw in the jacket, and the cross section of the sealing ring is trapezoidal. A fitting angle is arranged between the top of the holding jaw of the jacket and the bottom of the joint cap, a fitting angle is arranged between the bottom of the jacket and the sealing ring, and a fitting angle is arranged between the sealing ring and the inner end surface of the stepped hole of the joint body.
Description
The utility model relates to a kind of jacketed type pipe joint, and the connection that is used to carry the liquids and gases pipeline belongs to the pipeline fittings technical field.
In the metal tubes of carrying liquids and gases connects, use screwed pipe joint usually.When pipeline is installed, at first will be on pipe threading, apply sealing material again, give the internal thread that makes and be connected then with on the pipe joint, to finish the connection of metal tubes, not only work on the spot amount of this method is big, construction is inconvenient, and is not easy to after the pipeline connection adjust and overhaul.The design's purpose is at above-mentioned shortcoming, is intended to seek need not when a kind of pipeline connects on pipe threading and can realizes effective the sealing and fastening jacketed type pipe joint.
The Bite type fittings technical characteristics is with the effect difference in the utility model and the present pipe joint, Bite type fittings fastening and sealing are the pressure that cutting ferrule is subjected to joint cap, and the cutting ferrule cutting edge cuts under the cooperation of fittings body step hole inwall and interior step end face that tube wall finishes.Its shortcoming is a cutting ferrule.The manufacturing of fittings body, connecting tube requires all higher.In addition, service condition is also narrow, as when water, steam pipe road connect, and cutting ferrule and fitting surface corrosion thereof, sealing was promptly lost efficacy.So Bite type fittings is not widely adopted in connecting on ordinary water, steam pipe road, the fastening and sealing of the utility model jacketed type pipe joint is that chuck is moved down by the pressure of joint cap, the compressing rubber ring, the rubber ring stress deformation fits tightly with pipe outer wall and step hole inwall and finishes sealing, joint cap continues to exert pressure downwards simultaneously, the wedge that cooperates between joint cap and the chuck forces the claw that fluting forms on the chuck, inwardly shrinks and finishes fastening.
The utility model has the advantages that: simple in structure, easily manufactured, be connected firmly, seal reliable, need not at the construction field (site) pipe is put tooth, also sealing material has not alleviated working strength of workers, install and maintenance all very convenient.
The utility model structural feature is: pipe is that sealing of employing sidewall and jaw are fastening, the suitable distance so pipe can freely rotate in fittings body and advance and retreat; The fastening piece of pipe joint is outside Sealing, do not contact with the liquids and gases of carrying, therefore be difficult for corrosion, mounting or dismounting are convenient, the elastic deformation amount of rubber seal is big, so usage requirement is not high, it is suitable for common pipeline and connects, in inflammable, perishable, poisonous liquid, gas piping connect, can change rubber seal into the lead alloy seal circle and also can reach effect same.
Structure of the present utility model as shown in drawings, by joint cap 1, chuck 2, seal ring 3, fittings body 4 is formed.Now the utility model is described in further detail in conjunction with the accompanying drawings.
Accompanying drawing is a kind of straight-through jacketed type pipe joint structure schematic representation, and as shown in the figure: joint cap 1 is outer octagon, and an internal thread is arranged, the screw thread end has chamfering in, and several grooves are arranged on the chuck 2, and there is a ditch in the garden groove portion of moving back in the chuck, form jaw thus, the hardness of jaw is greater than the hardness of tube material; Jaw one end of chuck 2 have one with joint cap 1 in the same outer chamfering of chamfer angle, the other end has an interior chamfering to contact with the lateral angle of seal ring 3, seal ring 3 cross-section are trapezoidal, can increase tube wall sealing area and pressure like this, chamfering matches in 2 times chamferings of trapezoidal angle and chuck and fittings body 4 step holes, fittings body 4 has a step hole, chamfering is identical with the trapezoidal angle of seal ring in the step hole, the end has outside thread to be connected with joint cap 1, the centre is a through hole, the size of through hole is slightly larger than tube outer diameter, rotates freely in fittings body and advances and retreat to guarantee connecting tube.
This free flow coupling two-end structure is just the same, in fittings body 4 two ends step holes, place seal ring 3, the chuck 2 of rubber system during use, when screwing on joint cap 1, work, the pipe good saw directly inserts in the corresponding pipe joint, screw joint cap 1, thereby chuck 2 is subjected to the pressure of joint cap 1 to move forward compressing seal ring 3, can't be out of shape until seal ring 3, at this moment, the outer chamfering of claw is inwardly shunk to power by the wedge of chamfering in the joint cap 1 on the chuck 2, thereby with tube grip.
Claims (2)
1, a kind of jacketed type pipe joint, it is characterized in that: a through hole is arranged in the fittings body, its internal diameter is slightly larger than the connecting tube external diameter, there is a step hole end, built-in ring, chuck, the step hole outside has screw thread to be connected with joint cap, have vertical slot on the chuck, garden groove root has garden week ditch and forms jaw in the chuck, the cross section of seal ring is trapezoidal, chuck jaw top and joint cap bottom has one to cooperate the angle, has one to cooperate the angle bottom the chuck with between the close circle, has one to cooperate the angle between seal ring and the fittings body step hole interior edge face.
2,, it is characterized in that seal ring can make with rubber or lead alloy by the described jacketed type pipe joint of claim 1.
