Abstract

Disclosed is a plastic square elbow which comprises two pipe heads which form a right angle with each other, wherein British standard pipe threads are respectively arranged on the two pipe heads, and the pipe heads are made of rigid polyvinyl chloride (PVC-U) materials. The plastic square elbow is formed by injection molding with the pipe heads, the process is simple, the cost is low, the plastic square elbow can be used for connecting zinc-plating pipes in a right angle mode, the connection in a hot melting mold between plastic water pipes can be changed in the connection through threads simultaneously, and installation and maintenance are convenient.

Description

A kind of plastics elbow bend
Technical field
The utility model relates to the pipe fitting technical field, relates in particular to a kind of elbow that water pipe connects usefulness that is used for.
Background technique
Plastics are different with traditional material, and the paces of technological progress are faster, and the new technology, new material, the new process that constantly occur make the advantage of the relative traditional material of plastic water pipe more and more outstanding.The plastic water pipe material is compared with traditional galvanized pipe, has advantages such as price is low, in light weight, and weight generally is merely the 1/6-1/10 of metal tube, and corrosion resistance, shock resistance, tensile strength are preferably arranged, and compressive strength also meets the demands.The plastic water pipe internal surface is more smooth than galvanized pipe, friction factor is little, fluid resistance is little, can reduce the water delivery energy consumption more than 5%.Galvanized pipe uses for a long time in addition, can occur getting rusty and the appearance of impurity, makes the quality of pipeline descend.Therefore increasing galvanized pipe and pipe fitting are replaced by plastic water pipe and pipe fitting, are widely used in each occasion.
The plastics elbow bend comprises two tube heads at right angle each other at present, when the right angle connects between two plastic water pipes, adopts the hot melt Placement to connect, and is when water pipe keeps in repair, very inconvenient.This plastic water pipe elbow bend interaction is relatively poor, and weatherability is poor, is prone to wear out, and can not use on other water pipes such as galvanized pipe to connect.The plastic water pipe elbow bend that use is also arranged, its two tube heads are embedded in tapped metalwork, and this structure need embed metal insert when making, complex manufacturing technology, cost is high.
The model utility content
The purpose of the utility model is in order to solve the deficiency of above-mentioned existing technology, a kind of water pipe elbow bend to be provided, and its cost is low, and technology is simple, and the right angle that can be used for water pipes such as plastic water pipe, galvanized pipe connects, beautiful shape, and installation and maintenance are convenient.
The technological scheme that technical problem adopted that the utility model solves is:
A kind of plastics elbow bend comprises two tube heads at right angle each other, it is characterized in that two tube heads are provided with screw thread.Above-mentioned screw thread is with the tube head straight forming.
Above-mentioned screw thread is an internal thread.
Above-mentioned screw thread is an outside thread.
Above-mentioned screw thread one end is an internal thread, and the other end is an outside thread.
As preferably, above-mentioned screw thread is a pipe thread made in Great Britain.
As preferably, above-mentioned tube head is the tube head of PVC material.
As preferably, above-mentioned tube head is the tube head of PVC-U material.The PVC-U pipe fitting is to be that raw material wanted in literary composition with health grade PVC (PVC) resin, adds an amount of non-toxic stabilizer, oiling agent, bulking agent etc. through plastic extruder extruding and moulding and injection machine molding and forming.
The beneficial effect of the utility model is: the utility model adopts and tube head molding and forming screw thread; Its processing technology is simple; Cost is low, and the right angle that can be used between the galvanized pipe connects, and can change simultaneously to adopt hot melting mode to connect between plastic water pipe; Employing is threaded, and installation and maintenance are convenient.
Description of drawings
Below in conjunction with accompanying drawing and embodiment model utility is further specified.
Fig. 1 is the utility model first embodiment's a structural representation.
Fig. 2 is the utility model second embodiment's a structural representation.
Among the figure: 1, tube head 2, internal thread 3, outside thread.
Embodiment
Embodiment 1
In Fig. 1, a kind of plastics elbow bend is the PVC-U material, comprises in 1, two tube head of two tube heads at right angle each other being provided with internal thread 2, and internal thread 2 is an internal thread made in Great Britain.
Embodiment 2
In Fig. 2, a kind of plastics elbow bend is the PVC-U material, comprises that 1, two tube head of two tube heads at right angle is provided with screw thread each other, and screw thread one end is an internal thread 2, and the other end is an outside thread 3.
Above-mentioned two model utility embodiments adopt the screw thread with the tube head moulding, and its processing technology is simple, and cost is low; Can be used for the direct connection between the galvanized pipe; Can change simultaneously and adopt hot melting mode to connect between plastic water pipe, employing is threaded, and installation and maintenance are convenient.
At last, it is also to be noted that what more than enumerate only is the specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive from the disclosed content of the utility model or associate all should be thought the protection domain of the utility model.
