Abstract
Disclosed is a plastic pipeline connector joint, which comprises a pipeline upper joint and a pipeline lower joint connected with each other on an axle center of the same cylinder, and is characterized in that: an annular lug is connected along the external surface of the plastic pipeline connector joint, is positioned between the pipeline upper joint and the pipeline lower joint, and is vertical to the axle center of the cylinder; and a straight-through passage positioned on the axle center of the same cylinder with the pipeline lower joint is connected on the external surface of the pipeline lower joint. More than two through holes are evenly distributed on the annular lug along the circumference of the lug. The utility model can realize functions of the connector joint for the connection of pipelines at both ends, and can also realize the connection of a branch pipeline mode. The plastic pipeline connector joint is simple, flexible, convenient and applicable.
Description
Technical field
The utility model relates to the installing area of pipeline, particularly a kind of plastic cement bonded joint.
Technical background
The connection of plastic cement pipeline generally has adhesive connection, flange connection etc. in the prior art.But when concrete the installation, the connection interface place often relates to the pipeline of distinct interface, prior art head it off underaction.In general, realize the jointing that the two ends pipeline connects, can not realize the jointing of lateral pattern simultaneously.In addition at the jointing of lateral pattern, or can only realize that adhesive connects, or can only realize that flange connects, the restriction in this use has increased the complexity that plastic pipe connects.
The model utility content
The purpose of this utility model is exactly at above-mentioned deficiency, designs a kind of jointing that can realize that the two ends pipeline connects, can realize a kind of plastic cement pipe connector lug of the connection of lateral pattern again.Its simple and flexible, convenient being suitable for.
In order to solve the problems of the technologies described above, the utility model comprises following technological scheme: a kind of plastic cement pipe connector lug, comprise interconnective in the heart pipeline upper connection of same cylinder axis and pipeline lower contact, it is characterized in that: between pipeline upper connection and the pipeline lower contact, perpendicular to the cylindrical body axle center, be connected with a ring bead along described plastic cement pipe connector lug outer surface; Described pipeline lower contact outer surface is connected with straight-through with the same cylinder of pipeline lower contact axle center.
The pvc material that described pipeline upper connection, pipeline lower contact, bead are one of the forming; Described pipeline lower contact outer surface is with straight-through bonding.
Described straight-through internal surface vertically is provided with a ring locator protrusions.
Described locator protrusions upper surface arrives the axial distance of bead lower surface to the axial distance of straight-through upper end less than it.
On the described bead, be evenly distributed with two above through holes along the bead circumference.
Described bead is provided with sealing gasket; Described sealing gasket is provided with the pilot hole that matches with through hole.
Be equipped with double-screw bolt in described through hole and the pilot hole, the other end of double-screw bolt is connected with nut.
Compared with prior art, the utility model perpendicular to the cylindrical body axle center, is connected with a ring bead along described plastic cement pipe connector lug outer surface between pipeline upper connection and pipeline lower contact.When the two ends pipeline connected, this ring bead played the location and the position-limiting action in upper connecting tube road.When the lateral pattern connected, the ring bead played the effect of connection.The user can be in needs directly perforate on main pipe, and bead is connected with main pipe by adhesive, and pipeline lower contact outer surface is with straight-through bonding, and is connected with lateral by adhesive with leading directly to, thus realization lateral connection mode.Also can be on bead at the utility model, along bead circumference some through holes that evenly distribute, so the user also can select the flange ways of connecting, changes piping erection according to actual needs at any time.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural drawing;
Fig. 2 is the utility model embodiment 2 a structural drawing.
Embodiment
The utility model embodiment 1 structure as shown in Figure 1, a kind of plastic cement pipe connector lug, comprise interconnective in the heart pipeline upper connection 1 of same cylinder axis and pipeline lower contact 2, between pipeline upper connection 1 and the pipeline lower contact 2, perpendicular to the cylindrical body axle center, be connected with a ring bead 3 along described plastic cement pipe connector lug outer surface, described pipeline lower contact 2 outer surfaces are connected with and straight-through 4 of pipeline lower contact 2 same cylinder axle center.Straight-through 4 purpose is the bond area that increases pipeline lower contact 2 and descending pipeline, strengthens the dynamics of pipe bonding.
In the utility model, described pipeline lower contact 2 outer surfaces are bonding with straight-through 4; Described straight-through 4 internal surfaces vertically are provided with an annulus morpheme projection 5; Described locator protrusions 5 upper surfaces arrive the axial distance of bead 3 lower surfaces to the axial distance of straight-through 4 upper ends less than it.
For convenient for production, the pvc material that described pipeline upper connection 1, pipeline lower contact 2, bead 3 are one of the forming; Described pipeline lower contact 2 outer surfaces are bonding with straight-through 4.
When the two ends pipeline connects, up-hill line and pipeline upper connection 1 adhesion, the inner surface diameter of up-hill line equals pipeline upper connection 1 outer surface diameter, and up-hill line is plugged on the surface of pipeline upper connection 1, and described ring bead 3 plays up-hill line location and position-limiting action.Pipeline lower contact 2 is connected by adhesive with straight-through 4, leads directly to 4 and is connected with descending pipeline by adhesive.
When the lateral pattern connected, ring bead 3 played the effect of connection.The user can be in needs directly perforate on main pipe, and bead 3 is connected with main pipe by adhesive, pipeline lower contact 2 with lead directly to 4 and be connected by adhesive, lead directly to 4 and be connected with descending pipeline by adhesive.
The utility model embodiment 2 structure is as shown in Figure 2: on bead 3, be evenly distributed with two above through holes 6 along bead 3 circumference; Described bead 3 is provided with sealing gasket 7; Described sealing gasket 7 is provided with the pilot hole 8 that matches with through hole 6; Be provided with double-screw bolt 9 in described through hole 6 and the pilot hole 8, the other end of double-screw bolt 9 is connected with nut 10, and other structure is identical with embodiment 1.
