Abstract
A plastic connecting piece belongs to the technical field of connecting devices or other fitting parts specially applicable to the combined utilization of a plastic manufactured pipe or a plastic made pipe, and is convenient to connect and embed in a hidden way, and is durable. The plastic connecting piece provided by the utility model has the structural key point that at least two symmetrical bulges are arranged on the outer sides of the plastic connecting piece, and an alignment graduation is arranged on the plastic connecting piece.
Description
Technical field
the utility model is divided by International Patent Classification (IPC) (IPC) and is belonged to mechanical engineering, illumination, heating, weapon, explosion portion, engineering element or parts; For producing and keep the general measure of effective operation of machine or equipment; General adiabatic big type, pipe joint group, be specially adapted for the plastics manufacturing or the connection set or other accessory technical group fields that use with the pipe that plastics are processed; Relate in particular to a kind of plastic fastening.
Background technique
adopt the cold galvanizing steel pipe as supplying drainage, general working life less than 5 years with regard to corrosion, iron taste is serious.Plastic tube is compared with the traditional metal pipeline; Have from heavy and light, corrosion-resistant, compressive strength is high, safe and sanitary, resistance to water-flow are little, energy saving, saving metal, better people's living environment, long service life, characteristics such as easy for installation, received the favor of pipework circle and occupied considerable position.
adopt atactic copolymerized polypropene through being extruded as tubing to being three type PA tubes again, and injection moulding becomes pipe fitting, are the novel plastic pipeline products of Europe Application and Development at the beginning of the nineties.The PP-R pipe the characteristics such as general plastic tube is in light weight, corrosion-resistant, non-scaling, long service life, also has following main feature: (1) nontoxic, health except having.The raw molecule of PP-R has only carbon, protium, does not have harmful, poisonous element to exist, and not only is used for the hot and cold water pipeline, also can be used for the purified water for drinking system.(2) heat preservation energy-saving.PP-R pipe thermal conductivity is merely 1/200 of copper pipe for O.21W/mK.(3) better heat-resisting property.The Vicat softening point of PP-R pipe is 131.5 ℃.Maximum operating temperature can reach 95 ℃, can satisfy the usage requirement of water heating system in the building water supply and drainage standard.(4) long service life.The PP-R pipe under working pressure (P. N) the 1.OMPa condition, can reach more than 50 years 70 ℃ of operating temperatures working life; (20 ℃) can reach more than 100 years working life under the normal temperature.(5) easy for installation, connect reliable.PP-R has good welding performance, and tubing, pipe fitting can adopt hot melt to be connected with electric smelting, and easy for installation, joint is reliable, and the intensity of its connection part is greater than the intensity of tubing itself.(6) the recyclable utilization of material.The PP-R waste material is recycled in tubing, pipe fitting production after cleaning, fragmentation.The reclaimed materials consumption is no more than total amount 3%, does not influence quality of product.Can be widely used in: the cold and hot water supply system of building comprises central heating system; Heating system in the building, comprise floor, wallboard and panel type heating system; Purified water supply system capable of direct drinking; Central authorities' (concentrating) air-conditioning system; Industrial pipe-line systems such as conveying or discharging chemical mediator.
link in the market is the plastic pipe of circle basically for the outside.But in actual use, we find: (1) can only tighten with box spanner when pipe fitting is screwed, and is prone to cause pipe fitting surface breakdown and reduction in strength.(2) because the link external diameter is more a lot of greatly than connecting tube external diameter, and it is linear that peak is, when pipe fitting secretly buries, shallow in burial, through after a while, link position metope can ftracture; Buried deeply, constructional difficulties damages body of wall.(3) firm inadequately, the insufficient strength of link.(4) connect the bad grasp of torsion.
Summary of the invention
the utility model is exactly to the problems referred to above, a kind of connection is provided, secretly buries conveniently, durable plastic fastening.
are for realizing above-mentioned purpose; The utility model adopts following technological scheme; The utility model comprises plastic fastening, and the arranged outside of its structure outline plastic fastening has at least two symmetrical boss, and plastic fastening is provided with the aligning groove.
as a kind of preferred version, the said boss of the utility model is four, and symmetrically.
as another kind of preferred version, the said aligning groove of the utility model is arranged on the middle part of said boss.
as another kind of preferred version, the said plastic fastening of the utility model is straight-through plastic fastening.
as another kind of preferred version, the said plastic fastening of the utility model is the elbow plastic fastening.
in addition, the said plastic fastening of the utility model is the threeway plastic fastening.
secondly, the said plastic fastening of the utility model is the PP-R plastic fastening.
the utility model beneficial effect: (1) is durable.The arranged outside boss of the utility model plastic fastening is equivalent to be provided with reinforced block, has strengthened the pulling force of hot melt tie point.
(2) are easy to connect, not fragile.The utility model boss surface is the plane, and is symmetrically set; Like this, when connecting, available active open-end wrench chucking, plastic fastening is subject to damage not.In addition, the utility model plastic fastening is provided with the aligning groove, is convenient to the tubing alignment and connects, and makes connection torsion suitable.
Secretly bury conveniently
(3).The utility model boss surface is the plane, and the plane contact body of wall is not easy to crack, and dark buried depth degree is shallower than the round plastic link.
Description of drawings
are clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model are further elaborated.Should be appreciated that embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model example structure schematic representation.
Fig. 3 is another example structure schematic representation of the utility model.
Among
figure, 1 is that plastic fastening, 2 is boss for aiming at groove, 3.
Embodiment
