Description
Technical field
This utility model relates to tubing installation, technical field of construction, specifically, is a kind of tube connection piece.
Background technology
In current tubing work progress, need between two sections of adjacent tubing to be attached, through.When being connected with each other between tubing, connector is often inserted tubing by the mode of connection, then passes through the mode of compression and realizes connector and be connected with tubing, and then realizes the connection between tubing with tubing, connects.
The Chinese utility model patent that the patent No. is 96249125.X discloses a kind of pipe fitting being prone to comb and pipe connections, including pipe fitting and pipe connections, this pipe fitting periphery wall is provided with the prominent line of longitudinally convex expression, this pipe connections includes centrally located entity portion and is positioned at the connecting portion at two ends, the internal perisporium of this connecting portion is correspondingly provided with the prominent line insertion groove of recessed expression, periphery wall correspondence position at this connecting portion is provided with triangle indications, and the prominent line of expression on this pipe fitting is inserted in the prominent line insertion groove of expression of this pipe connections.
Although such scheme can play connect between tubing, the effect of connection, but the tube connection piece of traditional approach is directly exposed as easy as rolling off a log to be graded corrosion by extraneous moisture, salt outside, affects the reliability of tubing connection, affects construction quality.It addition, the connected mode fastness of such scheme is poor, tubing is, disconnection damaged in junction easily.
Therefore, it is thus achieved that a kind of corrosion resistance is strong, connect reliable tube connection piece becomes the target of emphasis that those skilled in the art study all the time and pursuit.
Utility model content
For solving the technical problems such as existing tube connection piece corrosion resistance is poor, the utility model discloses a kind of tube connection piece, improve the corrosion resistance of tube connection piece, tube connection piece is made to be difficult to be corroded by outside moisture or salinity, and be connected firmly between connector and tubing, good reliability, it is ensured that construction quality.
For realizing above-mentioned technical purpose, this utility model provides a kind of tube connection piece, including the joint that hollow pipe and hollow pipe extend to two ends respectively；Hollow pipe outer surface has anticorrosion layer, inner nosepiece wall to be embedded with rubber ring and quoit.
This utility model from moisture, salinity corrosion, increases the service life of tube connection piece, thus ensure that construction quality by anticorrosion layer protection hollow pipe.It addition, by rubber ring, quoit structure, it is achieved it is tightly connected between tube connection piece with tubing, connects.
Further, anticorrosion layer extends radially out the fin of bar shaped, and fin has the side that at least one is smooth, adjoining with anticorrosion layer surface.
Fin has assembles the effect that little water droplet, guiding hollow pipe surface dew or steam are dirty, reduces and even avoids the steam corrosion to tube connection piece, improves the corrosion resistance of tube connection piece.
Further, assembling the effect of little water droplet for strengthening fin, lug center line and hollow pipe axis angle are acute angle.
Further, fin cross section triangularity.
Further, including the two symmetrically arranged fins of row, often row's fin number is two or more.
Further, often in row's fin, plural fin be arranged in parallel.
Further, quoit is positioned at the inner side of rubber ring, and from hollow pipe mediad direction of both ends, rubber ring, quoit set gradually, and so arrange sealing effectiveness better.
Further, rubber ring, quoit diameter are identical.
Further, for protection blank area, joint outer surface has anticorrosion layer.
Further, joint external diameter is more than hollow pipe external diameter.
The beneficial effects of the utility model are: tube connection piece of the present utility model has the effect suppressing its generation surface corrosion phenomenon, and corrosion resistance is stronger, it is ensured that construction quality, and for the construction environment that moisture or salinity are more, effect of the present utility model becomes apparent from；And tube connection piece of the present utility model can be tightly connected tubing securely, connection reliability is higher.

Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model carried out detailed explanation and explanation.
As shown in Figure 1, 2, 3, this utility model provides a kind of tube connection piece, including the joint 10 that hollow pipe 1 and hollow pipe 1 extend to two ends respectively, hollow pipe 1 and joint 10 are structure as a whole, hollow pipe 1, joint 10 are generally adopted metal material, such as steel pipe or compo pipe, it is possible to use nonmetallic materials；For protection tube connection piece from corrosion; hollow pipe 1 outer surface has anticorrosion layer 5; anticorrosion layer 5 can be regarded as and is difficult to material layer that is oxidized or that be corroded; such as polytetrafluoroethylmaterial material layer; the mode that can pass through to spray or smear arranges anticorrosion layer 5 at hollow pipe 1 outer surface; and the anti-corrosion condition that can require according to tube connection piece, the position of the coating of anticorrosion layer 5, coated area size and coating thickness are reasonably set.Joint 10 is used for connecting tubing 4, joint 10 internal diameter is more than tubing 4 external diameter, tubing 4 inserts in joint 10, joint 10 inwall is embedded with rubber ring 3 and quoit 2, as shown in Figure 2, for convenience of crimping operation, this utility model is by the quoit 2 of conventional crimping tool squeezed joint 10 and joint 10 inwall, make joint 10, quoit 2 deforms upon, and then extruding rubber ring 3, rubber ring 3 compresses tubing 4, realize being tightly connected between joint 10 and tubing 4, make tubing 4, connected state it is between tube connection piece, part outside figure center tap 10 is the crimping tool of a kind of common type；For realizing being easier to, sealing more closely, as shown in Figure 1, from hollow pipe 1 mediad direction of both ends, rubber ring 3, quoit 2 set gradually, inboard is rubber ring 3 for quoit 2, outside, rubber ring 3 in the present embodiment, quoit 2 diameter are identical, it is easier to realizing being tightly connected, joint 10 external diameter is more than hollow pipe 1 external diameter.
As shown in FIG. 4,5,6, 7, for avoiding hollow pipe 1 surface sweating, hollow pipe 1 is caused corrosion, this utility model hollow pipe 1 outer wall is provided with fin 6, can process fin 6 by the mode of painting coating, and fin 6 suppresses tube connection piece to corrode by avoiding tube connection piece surface sweating.Specifically, such as Fig. 4, shown in 7, anticorrosion layer 5 extends radially out the fin 6 of bar shaped, fin 6 has the side that at least one is smooth, side is adjoining for path and anticorrosion layer 5 surface flowed down as water droplet, and the side of fin 6 has induction and produces the effect of dripping phenomenon, and little water droplet or steam can pool big water droplet in the side of fin 6 and drip, the water droplet on hollow pipe 1 surface is easier to dirty, thus solving the condensation trouble on hollow pipe 1 surface.For improving convergence effect, as shown in Figure 6,7, this utility model fin 6 centrage and hollow pipe 1 axis angle are acute angle, fin 6 cross section triangularity, including the two symmetrically arranged fins 6 of row, the number often arranging fin 6 is two or more, and often in row's fin 6, two or more fin 6 is arranged in parallel relation.
It addition, this utility model joint 10 outer surface has anticorrosion layer 5, reach the purpose of protection joint 10.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and simple modifications etc. made in this utility model flesh and blood, should be included within protection domain of the present utility model.
