Description

A kind of steel wire plastics composite pipe link

Technical field

The utility model relates to a kind of steel wire plastics composite pipe, is specially a kind of steel wire plastics composite pipe link.

Background technique

At present, the connecting means of known steel wire plastics composite pipe is mainly the connection of iron flange dish, withholds the pipe fitting connection.Above connecting means is by iron flange dish, bolt, nut and sealing gasket two tubing to be linked together.Link must be worked into tubing in job shop, and pipe fitting and tubing transport simultaneously in the transportation process, and metal pipe element causes damage to tubing easily, increases cost of transportation simultaneously.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that above connection exists, a kind of steel wire plastics composite pipe link is provided, avoid effectively store, in the transportation process pipe fitting to the damage of tubing, reduced cost of transportation, this link separates with composite pipe, utilize link that composite pipe is fused in twos at the connection scene, and simple to operate, easy to connect.

The design proposal that the utility model is taked is: a kind of steel wire plastics composite pipe link, comprise pipe collar, seal ring, backup ring, opposite opened anchor clamps, and it is characterized in that the pipe collar internal diameter A at described pipe collar middle part is suitable with described steel wire plastics composite pipe external diameter; The pipe collar internal diameter B at the pipe collar two end part of symmetry forms the ring cavity that supplies seal ring and backup ring to fill in greater than described steel wire plastics composite pipe external diameter through between B and steel wire plastics composite pipe in the pipe collar; The flange edge of the oriented outer lug of pipe collar two ends afterbody of symmetry; The both end sides of pipe collar respectively has the opposite opened anchor clamps of one pair of symmetry, and the opposite opened anchor clamps are provided with the flange catching groove corresponding with aforementioned flange edge with the pipe collar connecting end; The intrados diameter of opposite opened anchor clamps is slightly less than described steel wire plastics composite pipe external diameter, and the ripple pawl of fastening effect has been arranged on the inner arc diametric plane; The place of splitting of opposite opened anchor clamps has the radially outer anchor clamps of splitting to connect retaining, and this is split the anchor clamps connection and has blocked screw.

More specifically, for installing and locating, can be provided with the positioning retainer ring that with described pipe collar be connected as a single entity of internal diameter in the centre of described pipe collar less than steel wire plastics composite pipe external diameter.

The axial section of described seal ring is " Y " or " U " type, when installing like this seal ring is filled in easier formation selfsealings in the ring cavity that forms between pipe collar and the steel wire plastics composite pipe.

Placement: earlier two joint steel wire plastics composite pipes are put behind seal ring and the backup ring being inserted in the pipe collar, and make the end of the two steel wire plastics composite pipes that insert be in the centre of pipe collar; Again seal ring and backup ring are tucked in the described ring cavity; Flange catching groove with the opposite opened anchor clamps is buckled on the flange edge at described pipe collar two ends again, by bolt the opposite opened anchor clamps is connected the retaining fastening at last and promptly finishes connection.

Above-mentioned Placement is more suitable in the connection of the steel wire plastics composite pipe of elevated pressures.The connection of the highest pipeline applicable to nominal pressure 3.5Mpa.

Described pipe collar is metallic parts.Seal ring is a rubber product.

The seal ring baffle ring is used for bearing the pressure of liquid in pipe to seal ring.Longitudinal pulling force when the opposite opened anchor clamps bear two composite pipe pressure-bearings.

The beneficial effects of the utility model: utilize pipe collar, seal ring, backup ring and composite pipe outer wall to realize sealing, longitudinal pulling force when utilizing the opposite opened anchor clamps to bear the composite pipe pressure-bearing, and can realize that link and steel wire plastics composite pipe separate, and connect together the steel wire plastics composite pipe with link more in twos at the piping erection scene.Need not in job shop, link and composite pipe to be connected as a single entity.Avoid the damage that link causes composite pipe in storage, transportation process effectively, and can reduce cost of transportation, operation is also simple, convenient.
