Abstract
The utility model relates to an aluminum-plastic connecting pipe and a pipe joint thereof. The aluminum-plastic connecting pipe and a pipe joint thereof are composed of a connecting pipe and joints used for connecting. The connecting pipe is a composite pipe which is composed of an inner plastic pipe, an outer plastic pipe, and a middle aluminum pipe. The joints are a connecting screw cap and a locking ring which are arranged outside the composite pipe. A sealing ring is installed on the outer wall of a joint plug which is arranged in the composite pipe. The aluminum-plastic connecting pipe and the pipe joint thereof have the advantages of easy bent, easy cutting, height resistance, low temperature, corrosion resistance, heat insulation, heat preservation, etc. The joints cause the connection of pipe to be labour-saving and time-saving, which is very convenient. The steel-plastic pipe with a flexible joint can be suitable for hot and cold pipe systems of an industry, a civil building, etc.
Description
The utility model relates to connecting tube and pipe connects, and mainly is applicable to hot and cold water gas pipeline system in industry and the civil building, for example cold and hot pipeline, shower, water tap, the Shui Zui of tap water, and the connection of water pipe such as toilet.
In pipelines such as water pipe, connecting tube commonly used, existing connecting tube kind is a lot, can be divided into steel pipe, aluminum pipe, copper pipe and plastic tube etc. by its material difference, for the ease of bending, metal bellows and plastic film capicitor is arranged again.According to the pipeline difference of using, the fitness for purpose connecting tube is not only hard but also can be crooked, has characteristics such as heat resisting and pressure resisting is corrosion-resistant simultaneously.But existing metal tube need be heated when bending, troublesome poeration, and performance change, and there are shortcomings such as intensity is relatively poor in bellows.Be that existing metal or plastic union pipe and pipe connect to adopt and be threaded on the other hand, make trouble, install inconveniently, it is time-consuming to require great effort.And existing connecting tube antiseptic property is relatively poor, damages easily under low temperature or high temperature, has influenced working life.
The purpose of this utility model provides a kind ofly makes connecting tube with composite material, easily crooked, stable performance, and heat-resisting cold-resistant scope is big, and corrosion resistance is strong; Match easy for installation is provided simultaneously, and laborsaving saving time connects firm pipe and connects.
The technological scheme that the utility model plastic-aluminum connecting tube and pipe thereof connect is: be made up of with the joint that is used to be connected connecting tube, its so-called connecting tube is that interior plastic tube, outer plastic tube and middle aluminum pipe are formed composite pipe, so-called joint is mounted in composite pipe outer coupling nut and clamp ring, be installed in the connector plug in the composite pipe, seal ring be installed at the outer wall of connector plug.
Plastic-aluminum connecting tube of the present utility model and pipe thereof connect, and its so-called clamp ring is a kind of trip ring, and open collar extension is enclosed within outside the pipe easily during installation.
Plastic-aluminum connecting tube of the present utility model and pipe thereof connect, and at the top of connector plug rubber washer are installed, and rubber washer seals to the top of tube and tube.
The utility model is that a kind of composite pipe made from plastics and aluminum alloy of three layers is as connecting tube.This connecting tube has the hard of metal tube, is easy to bending again and stretches, and does not have fragility in distortion, need not heating when crooked; Composite pipe cuts easily, easy construction, and energy and various pipe joint cooperate, and be easy to connect, firmly withstand voltage; Temperature resistant range is-40 ℃～110 ℃, and the acid-and base-resisting performance is good, and the sanitary index of material own is good; The heat preservation and insulation height, the heat conduction non-scaling, the conduction cooling no frosting, fire-resistant again difficult combustion, non-corrosive, long service life increases about 20 times than existing like product.This pipe joint structure is simple, when pipe is connected without tapping, in connector plug, seal ring are arranged, clamp ring is arranged outward, in the rotation of coupling nut, clamp effectively, it is firm to connect, the rapid operation saving of labor is very convenient.
Fig. 1 is that cross-sectional schematic is joined in the utility model plastic-aluminum connecting tube and pipe tipping thereof.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
The utility model relates to connecting tube and pipe connects, and connecting tube is formed composite pipe by interior plastic tube 6, outer plastic tube 4 and middle aluminum pipe 5, so be a kind of plastic-aluminum combined connecting tube.Pipe connecing is exactly the joint that connects between the tube and tube, the structure of this joint is to have to be installed in connecting tube (composite pipe) outer coupling nut 1 and clamp ring 3, the inner top of coupling nut has tapering, screw, compressing power to clamp ring 3 is big more, clamp ring is the annular shape of opening, thereby is subjected to external force pressure big more tight more to the tube outer wall contact.Being installed in has a connector plug 7 in the connecting tube, and seal ring 8,9 is arranged in the connector plug, and rubber washer 2 is arranged at the top, and connector plug is avoided crushing to pipe on the one hand, plays the seal action of pipe and pipe on the other hand.
Claims (3)
1, plastic-aluminum connecting tube and pipe thereof connect, formed with the joint that is used to be connected by connecting tube, it is characterized in that so-called connecting tube is that interior plastic tube (6), outer plastic tube (4) and middle aluminum pipe (5) are formed composite pipe, so-called joint is mounted in composite pipe outer coupling nut (1) and clamp ring (3), be installed in the connector plug (7) in the composite pipe, seal ring (8,9) be installed at the outer wall of connector plug.
2, plastic-aluminum connecting tube as claimed in claim 1 and pipe thereof connect, and it is characterized in that so-called clamp ring (3) is a kind of trip ring.
