Abstract
Provided is a new type of pipe fitting. An external pipe fitting and an internal pipe fitting assemble into an integration. The gap between the inner wall of the external pipe fitting and the external diameter of the internal pipe fitting is as thick as the wall of the pipe. The center of the internal pipe fitting is an air hole. The internal diameter and the external diameter of the pipe fitting are circulars. Thread teeth are arranged at both ends of the pipe fitting external diameter. The utility model with a good sealing performance and a strong tensile resistance and durability has a simple structure and is convenient and reliable to install and use. The utility model is mainly used for the PVC plastic pipe or the PE plastic pipe. The one type of pipe fitting can be used as two types of pipe fittings thus reducing (number of) the abnormity diameter variation pipe fittings. The utility model is suitable to the tap water pipe and the gas transmission pipe within 25 k pa.
Description
Technical field
The utility model belongs to a kind of combustion gas gas transmission pipe fitting.
Background technique
The combustion gas gas transmission pipe fitting that existing market is sold, every kind of model pipe fitting can only use same model tubing, and tightness, soundness instability, is connected with pipe fitting with common tubing, and Safety performance is poorer.Be connected with stainless steel pipe or copper pipe fitting with day Feng Guancai, safe mass is reliable, but the cost height, general family income is held product that can't stand high price, and copper, iron, aluminum pipe spare use a period of time, are easy to corrosion.Depend merely on O-ring seal or glue special sealing with plastic pipe, the tension poor durability is installed and used defectives such as inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to install reliable, good airproof performance, the novel pipe fitting that the tension durability is strong.
The purpose of this utility model is achieved in that a kind of novel pipe fitting, its main structure is that outer tube member and interior pipe fitting are combined as integral body, the outer tube member inwall is consistent with slit and tube wall thickness between the interior pipe fitting external diameter, interior pipe fitting center is a vent, pipe fitting internal diameter, external diameter are circular, and perhaps pipe fitting external diameter middle part sectional shape is square.Pipe fitting external diameter two ends are provided with worm tooth.The nut that is connected with worm tooth is set, the snap ring that is connected with pipe fitting, snap ring is provided with slit aperture.
The utility model is simple in structure, and is easy to install reliable, good airproof performance, and the tension durability is strong.Be mainly used in PVC plastic tube or PE plastic tube, a kind of model pipe fitting can be used as two kinds of model pipe fittings and uses, reduce special-shaped reducer pipe fitting, same model pipe fitting cost reduces by 4 times than metal pipe element, the industry standard that meets the NBS and the Ministry of Agriculture fully is applicable to that 25Kpa is with interior running water pipe and combustion gas pneumatic tube.

Embodiment
Below in conjunction with drawings and Examples present embodiment is further described.
A kind of combustion gas gas transmission novel pipe fitting, outer tube member and interior pipe fitting are combined as integral body, slit between outer tube member inwall and the interior pipe fitting external diameter, tube wall thickness according to national Specification is consistent, interior pipe fitting center is a vent, external diameter is that circle or pipe fitting external diameter middle part are abnormity in the pipe fitting, pipe fitting external diameter two ends are provided with worm tooth, when socket tubing, the pipe fitting nut are inserted in tubing one end, and then cover O-ring seal pipe fitting snap ring, tighten the pipe fitting nut in being inserted in pipe fitting, pipe fitting snap ring awl splay end is offered slit aperture, when tightening the pipe fitting nut, the pipe fitting snap ring inwardly shrinks locking tubing, improves the sealing of tubing and pipe fitting connecting head.
Fitting structure shown in the accompanying drawing 1, two ends, the left and right sides are interior pipe fitting external diameter 1, pipe fitting port 9; Two ends, the external diameter left and right sides are worm tooth 2; External diameter middle-end 3 is the light face.Left and right sides external diameter inwall and about in be 6 positions, pipe fitting slit between the pipe fitting external diameter; The pipe fitting center hole is interior pipe fitting vent 8.
Accompanying drawing 3, accompanying drawing 4 show the novel pipe fitting snap ring, lay when installing and using and be socketed in tubing one end, accompanying drawing 3 openings 10 should be best between 0.5mm～2mm apart from δ, accompanying drawing 4 openings 10 are 1/2 deeply, the opening external diameter is tapered, the other end tapering matches with chamfer angle in the pipe fitting two ends, and opening end 11 cooperates with an end of accompanying drawing 6, and the novel pipe fitting snap ring plays sealing and the effect of locking tubing.
Accompanying drawing 5, accompanying drawing 6 show the novel pipe fitting nut, and accompanying drawing 5 is a nut 13, and circular hole 12 is for covering the tubing position; Tooth matches with the worm tooth at pipe fitting two ends in the nut of accompanying drawing 6.
The novel pipe fitting structural principle that accompanying drawing 7, accompanying drawing 8, accompanying drawing 9 show is consistent with the structural principle of accompanying drawing 1, accompanying drawing 2, and just profile is different, and pipe fitting is installed with tubing, socketing method is identical, and the utility model is mainly used in the civilian pipe fitting of family.External diameter φ 10mm～40mm is between pipe fitting length L 30mm～90mm.
Novel pipe fitting is generally annotated with plastics and is pressed into shape, and flow is simple, the manufacturing efficiency height, and product cost is than low 4 times of same model, and it is convenient to install, change, the sealing height, the tension durability is strong.Novel pipe fitting can design produces through-type, curved, T type, Y type, L type, and novel pipe fitting does not need the glue special adhering and sealing, and is elegant in appearance, the iron of available forging casting method, copper, steel, aluminium processing and fabricating.
The utility model purpose provides external sealed in pipe fitting and the tubing, locking tubing is difficult for taking off head, gas leakage, connection gas transmission tubing is installed is not subjected to condition restriction, with an internal diameter φ 16mm pipe fitting, simultaneously can use external diameter φ 13mm, φ 14mm, φ 16mm flexible pipe or semihard tubing or hard tube material, one is φ 16mm gas transmission tubing, and the other end need become φ 13mm tubing, do not need special-shaped reducer pipe fitting, can connect on same pipe fitting, processing technology thereof is simple, mainly passes through castable.
