Abstract
The utility model relates to a composite bell mouth joint of elastic sealing ring connection, comprising a polyolefin plastic joint base body. A ring shaped arch used for embedding a sealing ring in the cavity is arranged on the joint base body. One end of the joint base body is single layer while other parts of the joint base body is covered with polyvinyl chloride plastic reinforced layer, forming a composite layer. The utility model has the advantages of high intensity and rigidity. Since the sealing ring can be embedded in the pipe joint, the flexible connection can be provided between the pipes and the pipe joint. Thus, good sealed effect is achieved. The utility model is characterized in that the connections between pipes are very convenient and fast; various composite joints can be combined, such as triple joint, cross joint and elbow. The composite bell mouth joint of elastic sealing ring connection is very convenient for the engineering construction.
Description
Technical field
The utility model relates to the plastic tube pipe joint.
Background technique
Connection between the tubing can directly connect, and also can connect by pipe joint.For example can adopt thread connecting mode to connect by metallic pipe coupling between the metal pipe; Generally be to adopt welding manner directly to connect between polyethylene (PE) tubing.Polyethylene (PE) tubing be use at present tubing more widely.Need to place and operating personnel certain requirement be arranged all also by welding equipment for the direct welding between the polyvinyl piping materials, not only inconvenient operation but also to connect the needed time long.If adopt the polyethylene pipe joint to connect polyvinyl piping materials, but, under pressure, occur dilatancy easily because material is softer.
The model utility content
The purpose of this utility model be to propose a kind of have certain rigid and with the compound bellmouth joint of tubing elastic seal ring fast easy to connect connected type.
For achieving the above object, the technological scheme that the utility model is taked is as follows: it comprises TPO plastic joint matrix, joint matrix is provided with the ring-type donor that can set seal ring in the chamber, and an end of joint matrix is an individual layer, and remaining part is coated with the igelite reinforced layer and forms composite bed.
Above-mentioned joint matrix is an individual layer from a ring-type donor end far away.
The single-layer portions radial contraction of described joint matrix forms neck, and the joint matrix the other end is on this end end face of composite bed and on the sagittal plane of neck and is coated with reinforced layer.
TPO plastic joint matrix is polyvinyl plastics joint matrix or polypropylene plastics joint matrix.
Set seal ring in the ring-type donor of joint matrix.
The utlity model has following characteristics:
1, the utility model is taked to be coated with the igelite reinforced layer on the joint matrix at TPO plastic joint matrix, utilizes the big characteristics of the big rigidity of pvc material Young's modulus, makes joint have higher intensity, rigidity.
2, be provided with the space that seal ring is installed in interlocking in the joint matrix of the present utility model, be used for installing seal ring, tubing is connected by seal ring with joint matrix, being connected between tubing and the pipe joint is flexibly connected, to reach good sealing effect.
3, application of the present utility model makes connection between the tubing very convenient fast, only need manual tubing to be inserted just, and the utility model can make various built-up joints, as threeway, four-way, elbow etc., brings great convenience to engineering construction.

Embodiment
Shown in Figure 1 is that embodiment 1 has polyvinyl plastics joint matrix 1 or polypropylene plastics joint matrix 1, joint matrix 1 molding and forming.Joint matrix 1 has ring-type donor 1-1, and ring-type donor 1-1 is used to set seal ring.Joint matrix be individual layer from a ring-type donor 1-1 end far away, remaining part is coated with igelite reinforced layer 2 and forms composite beds.The single-layer portions radial contraction of joint matrix 1 forms neck 1-2, and joint matrix 1 the other end is on this end end face of composite bed and on the sagittal plane of neck and is coated with reinforced layer 2-1,2-2, guarantees that pipe joint is indeformable under working pressure.Igelite reinforced layer 2 is by the quadric injection mould moulding.
Shown in Figure 2 is that embodiment 2 sets seal ring in the ring-type donor 1-1 of the joint matrix 1 of pipe joint A, and all the other are identical with embodiment 1.
Fig. 3 is the application examples of single tube joint, welds one section polyethylene or polypropylene plastics tubing B on the termination of the individual layer end 1-2 of joint matrix earlier, and this part work can be finished in factory.When using, need only the tubing that needs connect be inserted into the seal ring from joint socket, finish connection in the building site.
Fig. 4 is the double-pipe joint that is welded by two pipe joint A.Fig. 4 is the three-way pipe that is welded by three pipe joint A.Fig. 5 is the elbow that is welded by two pipe joint A.When using, need only be inserted into the tubing that needs connect from joint socket and promptly finish connection the seal ring in the building site.
