Quick coupling device is named again rapid pipe joint, it is the vitals in Novel connecting pipe road, this class rapid pipe joint is mainly for making the connecting end of body in the situation that not using any instrument, rapid, easy and couple together reliably at short notice, can be fast, simple, insurance ground repeat to connect and disconnection almost any fluid or gas pipeline.At present, in industry, the conventional design of the fittings body of Quick pipe joint mainly adopts monolithic construction, this integral joint is simple in structure, also substantially can meet the transmission of fluid foods, still, when using monolithic construction pipe coupling to implement docking, due to the normal twisting force that produces of flexible pipe rotation, be subject under the twisting force that rotation produces from flexible pipe, likely cause that joint lock is loosening, finally may cause pipeline to get loose, thereby cause fluid leakage.
Model utility content
The technical problem that the utility model solves is to provide a kind of rotary moveable formula Quick pipe joint, adopt a kind of joint inner sleeve, coating device of separation, joint inner sleeve seals by seal ring, by joint overcoat, be connected and lock with rotation lock ring, joint inner sleeve can be rotated freely in overcoat, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of rotary moveable formula Quick pipe joint, by two connector unit docking that overlap joint coordinates mutually, formed, in its each connector unit, include joint overcoat and be sleeved on the joint inner sleeve in joint overcoat, on the outer side surface of described joint inner sleeve one side, being provided with the spacing rank butt joint of circle overcoat carries out spacing, and joint inner sleeve can rotate freely around central shaft between joint overcoat, and the joint overcoat of described two connector units is the hook hanging groove structure of mating in pairs, and put outward and be all set with a rotation lock ring at two joints, between described rotation lock ring and joint overcoat, by hierarchic structure, be set with overlap joint, and it is spacing in its active side, to be provided with clip spring structure.
The connection of this rotary moveable formula Quick pipe joint is that the rotary moveable formula Quick pipe joint docking coordinating by a pair of mutual overlap joint forms.The seal ring of joint inner sleeve has guaranteed connection procedure ne-leakage, by jump ring, the engaging of the spacing of rotation lock ring and joint overcoat and rotation lock ring has been realized the snap-lock of Quick pipe joint.Can rotate freely the interior nested structure of Moveable joint can be in pipeline docking operation, when the twisting force that exists flexible pipe rotation to produce, joint overcoat is motionless, and joint inner sleeve can rotate freely activity, can realize the rapid abutting joint of joint inner sleeve like this, and without the whole joint of unitary rotation, thereby make joint docking convenient and swift.After butt-joint locking, joint overcoat together can not produce twisting each other, thereby between two overcoats of the rapid pipe joint of pairing and rotation lock ring, loosening possibility reduces greatly, has significantly improved the reliability of the product of practicing midwifery soon.
In the utility model, in joint, being enclosed within end face seals by an O RunddichtringO, O type circle seal ring in joint inner sleeve can be selected Viton seal ring, FFKM seal ring, EPT rubber packing circle, nitrile rubber seal ring, butyl seal ring according to different operating temperature range, to guarantee tightness and the liquid-tight property of rapid pipe joint.
In the utility model, joint wall thickness is designed to 4mm, and to guarantee that this adapter system has good mechanical property and service behaviour, the installation of each component and work do not interfere, whole product performance are reliable and stable, can complete smoothly moulding, processing and guarantee handling safety.
In the utility model, for guarantee can to rotate freely between joint inner sleeve and joint overcoat and rotation lock ring when docking, between joint inner sleeve and joint overcoat and rotation lock ring there is the gap of 0.2-0.5mm in combination interface.
Beneficial effect: the utility model adopts the combined connecting structure of joint inner sleeve, overcoat separation, and it is simple in structure, easy to maintenance, and cost performance is high, possesses reliable operation simultaneously, the correct contraposition of system, connecting moves be sensitive and accurate, tear, connect advantage quickly and easily open; Simultaneously, utilization can rotate freely nested structure in joint, the joint docking inconvenience that the torsion that while having eliminated fluid foods conveying, flexible pipe rotation produces causes and the locking device that may cause are loosening, effectively to guarantee the mobile safety and reliability of pipeline fluid foods in joint part; Can also select by dimensional changes and the material of rotary moveable formula Quick pipe joint, realize the transmission of different fluid medium, to meet multiple industrial use.
