Abstract
The utility model relates to a pipe member which is used for connecting pipes, more specifically a pipe member of a composite metal-plastic pipe. The pipe member of a composite metal-plastic pipe is composed of a clamping head body, an elastic open ring, an inner bush and a sealing ring, wherein, the clamping head body is an open structure in round tubular shape. The inner diameter of the clamping head body is matched with the outer diameter of a composite pipe, and both ends of the clamping head body are provided with bolt holes. The elastic open ring is in annular shape, and the outer wall of the elastic open ring is provided with a double-cone surface. The inner wall of the elastic open ring is provided with two flanges of which the cross sections are in sawtooth shape. An elastic opening is in diagonal cut joint mode. Both ends of the inner liner are small, and the middle part of the inner liner is a relatively large tubular shape. The outer diameter of the two small ends is matched with the inner diameter of the composite pipe. Each small end is provided with an annular groove, and an annular sealing ring is installed in the groove. The sealing ring is matched with the inner wall of the composite pipe. The inner bush is provided with an annular groove at the position corresponding the elastic open ring. The pipe member is used for connecting composite pipes. The utility model overcomes a plurality of defects of a traditional pipe member, such as small bearing capacity in axial direction, complicated structure, troublesome installation, etc.
Description
Technical field
The utility model relates to the pipe fitting that a kind of pipeline connects usefulness, definite a kind of composite metal-plastic pipe pipe fitting of saying so.
Background technique
The composite metal-plastic pipe pipe fitting of known technology has the flared type of employing Placement, and the FERRULETYPE of employing Placement is also arranged.The Placement of flared type is simple in structure, connects reliably, can bear higher axial force, but it need use special-purpose flaring tool; General screw thread FERRULETYPE Placement is easy for installation, need not special tool, but be only applicable to the connection of φ 63 following tubules, too big owing to the nut size for φ 63 above composite pipes, pipe fitting cost height, and setting tool heaviness make construction very inconvenient.Simple clamp band type connects, and just axially has clamping force at fastening screw trip bolt, when the flange on the collet body inner arc surface acts on compound pipe end like this, can not apply active force to composite pipe in whole circumference, thereby make the reliability reduction of pipe fitting connection.
Summary of the invention
Goal of the invention:
The purpose of this utility model be to provide a kind of simple in structure, be easy to install, connect again simultaneously reliable, compressive strength is high, installation and removal composite metal-plastic pipe pipe fitting very easily.
Technological scheme:
The composite metal-plastic pipe pipe fitting is made up of collet body, elastic opening ring, neck bush, seal ring.Wherein: collet body has adopted pipe shape opposite opened structure, its internal diameter and composite pipe external diameter coupling, and the collet body two ends have bolt hole; It is circular that elastic opening ring is, and it is planar that its outer wall is bipyramid, and it is zigzag flange that its inwall has the twice cross section, and elastic opening adopts the diagonal cut joint form; Neck bush is less, the middle big slightly pipe shape in two ends, the external diameter at its less two ends and the internal diameter of composite pipe coupling, and dug ring groove, and installing ring RunddichtringO in the groove, seal ring cooperates with the composite pipe inwall; Neck bush is having annular groove with the elastic opening ring corresponding part; All parts adopt nonpoisonous anti-corrosive paint spraying or anti-corrosion measures such as plating, chemical plating, and overall corrosion resistance can be extremely strong.
Beneficial effect:
After adopting said structure, make the pipe fitting connection overcome traditional composite pipe and bear many shortcomings such as axial force is little, complex structure, installation trouble with pipe fitting, its combination property is very superior, is a kind of composite metal-plastic pipe pipe fitting easy to utilize.
Description of drawings
Fig. 1 is the long splice composition during pipe fitting uses.
Fig. 2 is the structural drawing of elastic opening ring.
Among the figure: 1 collet body, 2 elastic opening rings, 3 neck bushs, 4 seal rings.
Embodiment
Be further described below in conjunction with drawings and Examples:
As shown in Figure 1, the composite metal-plastic pipe pipe fitting is made up of collet body (1), elastic opening ring (2), neck bush (3), seal ring (4).Wherein: collet body (1) has adopted pipe shape opposite opened structure, its internal diameter and composite pipe external diameter coupling, and the collet body two ends have bolt hole; It is circular that elastic opening ring is, and it is planar that its outer wall is bipyramid, and it is zigzag flange that its inwall has the twice cross section, and elastic opening adopts the diagonal cut joint form; Neck bush (3) is less, the middle big slightly pipe shape in two ends, the external diameter at its less two ends and the internal diameter of composite pipe coupling, and dug ring groove, and installing ring RunddichtringO (4) in the groove, seal ring (4) cooperates with the composite pipe inwall; Neck bush (3) is having annular groove with the elastic opening ring corresponding part; All parts adopt nonpoisonous anti-corrosive paint spraying or anti-corrosion measures such as plating, chemical plating, and overall corrosion resistance can be extremely strong.
Use the process that pipe fitting connects composite metal-plastic pipe:
The two composite pipe end special tool enlargings that earlier desire connected during installation, two compound pipe ends all put elastic opening ring (2), insert the flared end of a composite pipe at an end of the neck bush that will install seal ring (4) (3), again the flared end of another composite pipe is installed to the other end of neck bush (3); To be pushed to composite pipe joint recess to elasticity open type ring (2), at last chuck spare (1) be got final product with bolton pipe fitting joint.Because elastic opening ring (2) has adopted the diagonal cut joint form, the coupling mechanism force that chuck spare (1) is gone up bolt can be distributed to composite pipe metal layer outer surface by elastic opening ring (2), makes pipe fitting and pipe strong bonded; In the bipyramid face form that the outer wall of elastic opening ring (2) adopts, can make elastic opening ring location automatically when mounted; At the inwall of elastic opening ring the twice cross section being arranged is zigzag flange, and the clamping force of transmitting by collet body (1) makes elastic opening ring (2) and the metal layer outer wall interlock of composite pipe end produce corresponding deformation, pipe fitting is connected can bear higher thrust load; Neck bush (3) can make composite pipe end metal layer that distortion leeway is arranged having annular groove with elastic opening ring (2) corresponding part, on neck bush (3) outer surface seal ring (4) is housed and cooperates with the composite pipe inwall, realizes effectively sealing.
Claims (1)
1, a kind of composite metal-plastic pipe pipe fitting is characterized in that: this pipe fitting is made up of collet body (1), elastic opening ring (2), neck bush (3), seal ring (4); Wherein: collet body (1) has adopted pipe shape opposite opened structure, its internal diameter and composite pipe external diameter coupling, and collet body (1) two ends have bolt hole; Elastic opening ring (2) is circular, and it is planar that its outer wall is bipyramid, and it is zigzag flange that its inwall has the twice cross section, and elastic opening adopts the diagonal cut joint form; Neck bush (3) is less, the middle big slightly pipe shape in two ends, the external diameter at its less two ends and the internal diameter of composite pipe coupling, and dug ring groove, and installing ring RunddichtringO (4) in the groove, seal ring (4) cooperates with the composite pipe inwall; Neck bush has annular groove in (3) and elastic opening ring (2) corresponding part.
