Abstract
The utility model relates to a connecting component for a metal plastic composite pipeline, which is composed of a connecting component body and a pressing nut. The inner diameter of the connecting component body is consistent with the inner diameter of the pipeline to be connected. The end part of the connecting component body and the front end of the inner part of the pressing nut are made into the conical surfaces with a certain length and same conicity. The pressing nut is firstly sheathed on the pipeline and the end part of the pipeline is enlarged into a cone hole which is same to the conicity to be sheathed on the end part of the connecting component body and then the pressing nut is tightly screwed in connecting operation. The utility model increases the using rate of the flow capacity of the pipeline and avoids a water hammer phenomenon.
Description
The utility model relates to a kind of pipe joint, particularly a kind of composite metal-plastic pipe pipe joint.
At present, composite metal-plastic pipe obtains promoting in the building industry with its good performance gradually at home, becomes the substitute products of galvanized pipe.The pipe joint that generally adopts on the market, its working method with pipeline 4 insertion tube pipe connecting main bodys 1 inside, by tightening clamping nut 2, opening clip collar 3, seal ring 5, are realized the connection of pipeline as shown in Figure 1 again.This Placement requires the internal diameter of connected internal diameter of the pipeline greater than the pipe joint main body, so that connector main body inserts in the connected pipeline.The circulation internal diameter of pipeline has been dwindled in this design, makes pipeline lose its due design discharge, poly-right variation of circulation internal diameter, and easily producing the noise phenomenon is water hammer, and required link complex structure, processes loaded down with trivial details.
The purpose of this utility model is that design is a kind of simple in structure, rationally, can give full play to the design discharge of pipeline, avoids the composite metal-plastic pipe pipe joint of water hammer.
For achieving the above object, the utility model is taked following design proposal: this composite metal-plastic pipe pipe joint, be made of connector main body and clamping nut, the internal diameter of described connector main body is consistent with the internal diameter of the pipeline that will connect, and the end of connector main body is a conical surface; The interior forward end of described clamping nut has a conical surface, and the cone angle of this conical surface equates that with the cone angle of the described connector main body end conical surface its angular range is 35 °-55 °.
The utility model has the advantages that: the utility model the experiment proved that, because connector main body is identical with internal diameter of the pipeline, has improved the design discharge of pipeline greatly, has avoided the generation of water hammer especially; Reduce number of spare parts simultaneously, make processing simple.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is existing pipe joint structural representation
Fig. 2 is the utility model composite metal-plastic pipe pipe joint structural representation
Fig. 3 is the utility model composite metal-plastic pipe pipe joint clamping nut structural representation
Fig. 4 is the utility model composite metal-plastic pipe pipe joint agent structure schematic representation
As shown in Figure 2, the composite metal-plastic pipe pipe joint is made of connector main body 6 and clamping nut 7, and the internal diameter of connector main body 6 is consistent with the internal diameter of the pipeline 4 that will connect.
The structure of composite metal-plastic pipe pipe joint clamping nut as shown in Figure 3, the aperture of clamping nut is slightly larger than the external diameter of the pipeline that will connect, and its interior forward end is the conical surface with certain-length d.
The structure of composite metal-plastic pipe pipe joint main body as shown in Figure 4, the internal diameter of connector main body is consistent with the internal diameter of the pipeline that will connect.The conical surface with certain-length e is processed in its end, and the angle of the conical surface equates that with the cone angle of the inner conical surface of clamping nut angular range is 35 °-55 °.
When carrying out the pipeline connection, earlier clamping nut is enclosed within on the pipeline, the head of pipeline is expanded into certain-length with the identical taper hole of described clamping nut internal taper, be enclosed within again on the conical surface of connector main body end, tighten clamping nut, two conical surfaces compress pipeline, realize fastening and be tightly connected.
Compare with the flow of two groups of data below with regard to the utility model and existing pipe joint.
(a) with connect 1/2 " the internal diameter b=12mm of aluminium-plastic composite pipe is example.The insertion end wall thickness that the contrast link adopts is 1.8mm, and then link internal diameter c is 12-1.8 * 2=8.4mm
Its actual internal area
S1＝3.14×(c/2)
2＝3.14×(8.4/2)
2＝55.39mm
2
Link internal diameter of the present utility model equals the internal diameter b=12mm of aluminium-plastic composite pipe
Its actual internal area
S2＝3.14×(b/2)
2＝3.14×(12/2)
2＝113.04mm
2
Its flow has improved
(S2-S1)/S1＝(113.04-55.39)/55.39＝104.08％
(b) with connect 1 " the internal diameter b=20mm of aluminium-plastic composite pipe is example.The insertion end wall thickness that the contrast link adopts is 2mm, and then link internal diameter c is 20-2 * 2=16mm
Its actual internal area
S1＝3.14×(c/2)
2＝3.14×(16/2)
2＝200.96mm
2
Link internal diameter of the present utility model equals the internal diameter b=20mm of aluminium-plastic composite pipe
Its actual internal area
S2＝3.14×(b/2)
2＝3.14×(20/2)
2＝314mm
2
Its flow has improved
(S2-S1)/S1＝(314-200.96)/200.96＝56.25％
