Abstract
This invention provides a clamping tube element including a joint and a clamping cover, in which the joint includes an end and a core, the radial section of the end is greater than the core, said clamping cover is sleeved on the outer circle of the core and a connection structure is set between one end of the cover and the joint end, the joint is made of plastics.
Description
Technical field
The invention belongs to the pipe fitting technical field that tubing connects, particularly relate to a kind of clamp-press type pipe.
Technical background
Existing clamp-press type pipe is usually used in the connection of aluminium-plastic composite pipe, and it mainly comprises joint body, plastics back-up ring, chucking cover and seal ring.
The main deficiency of prior art is owing to do joint body with the copper metal material, stainless steel is made the chucking cover, contact with metal body or stainless steel chucking cover for fear of the tubing aluminium lamination, must add the electro erosion that a plastics back-up ring or protecting jacket prevent different metal, institute is so that the fitting structure complexity, the installation requirement height; And when using, be difficult to guarantee joint body, chucking cover, plastics back-up ring and connect steadiness between the tubing, promptly integrality is not strong, gets loose easily.
In order to overcome the not strong defective of integrality, existing pipe fitting is by being provided with getting loose between the parts that the stop ring annular knurl prevents pipe fitting on the joint body, but because process limitation, knurl depth is limited, be difficult to reach the spline effect, and chucking overlaps and joint body does not have direct anti-rotation, locking gear, is easy to generate during installation radially to rotate, and is easy to generate the seepage consequence after the rotation.
In addition, the joint body of existing clamp-press type pipe is provided with many zigzag fashion annular grooves, makes when tubing connects, and the zigzag fashion annular groove sharp angle of metallic material has axial tension easily the tubing internal layer to be caused to draw scratch, easily cause leakage, reduced the due intensity of tubing.
Whether and existing chucking cover will be reserved peep hole, be used for installation process observation tubing that tubing connects and be inserted into spacingly, has both made chucking nested structure complexity, also brings the inconvenience of installation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of " integrality " strong, simple in structure, easy for installation, little, the clamp-press type pipe that anti-loose leakage proof is remarkably productive weighing wounded property of tubing endoporus.
In order to realize the foregoing invention purpose, the technological scheme of employing is as follows:
A kind of clamp-press type pipe, comprise joint body and chucking cover, described joint body comprises body end and body core body, body end radially greater than the body core body, described chucking cover is placed in body core body periphery, and be provided with linkage structure between an end of chucking cover and the body end, described joint body adopts plastic material.
The present invention adopts plastic material to replace the joint body of original metal material; make pipe fitting not need to adopt labyrinths such as the plastics back-up ring of prior art or protecting jacket; just can reach than prior art is better and prevent the metal electro erosion; and the proportion of plastic material is lighter more than 4 times than metal, makes that also the cost of joint body is lower.
In the technique scheme, described body core outer surface is provided with seal groove, and pipe fitting also comprises the elastic seal ring that is arranged on the seal groove.By seal ring and seal groove, sealing when having guaranteed the pipe fitting application and the steadiness between accessory.
Described body core outer surface also is provided with and prevents the back-off sawtooth annular groove that axially pulls.When guaranteeing to be applied to the tubing connection, connect tubing and can not take place axially pull with joint body by back-off sawtooth annular groove.
Described body core outer surface also is provided with radially spline convex tendon.When guaranteeing to be applied to tubing and connect, connect tubing and can not take place radially pull with joint body by spline convex tendon radially.
Described body core body front end outer surface also is provided with waveform circular arc annular groove.Described waveform circular arc annular groove can be avoided the scratch pipe material inner wall when tubing connects, because the core body of joint body is provided with back-off sawtooth annular groove and reaches radially spline convex tendon, in order to reach the purpose of anti-slip, all must contact with the inwall of tubing, so when mounted, if firmly accidentally, often easy scratch pipe material inner wall, and the waveform circular arc annular groove of the present invention by being provided with, when tubing is planted installation, waveform circular arc annular groove can supply the certain elastic space that is subjected to squeeze deformation of body core body, and can recover deformation after installing, and avoids the scratch pipe material inner wall.
Linkage structure between described chucking cover and the body end adopts in body end and chucking cover protruding key and the keyway that coincide mutually is set respectively.
Further, described chucking cover adopts the stainless steel straight tube, and the two ends of stainless steel straight tube are provided with the importing horn mouth, and wherein at least one end is provided with and the identical keyway of the protruding key of body end.
The structure of protruding key and keyway makes that the chucking cover is more convenient when mounted with joint body, makes that also the integrality after installing is stronger.
Joint pipe fitting good connecting effect of the present invention, button " integrality " is better, simple in structure mutually between after joint body, tubing, chucking overlap and engage, installation is more convenient, and is little to weighing wounded property of tubing endoporus, anti-loose leakage proof is remarkably productive, solves prior art easily pine, leakage problems are installed.
The present invention can be applicable to any end or the above pipe fittings such as the above multichannel water knockout drum of straight joint, elbow, threeway or threeway joint that connect flexible pipe of an end, is applicable to that flexible pipes such as PE-X pipe, aluminium-plastic composite pipe connect.
