Abstract
The utility model discloses a medium-bore and small-bore pressure pipelines quick connecter which can connect the medium-bore and small-bore pipelines feeding the liquid or gaseous meson quickly without leakage. The pipeline quick connector includes a locking cavity body, a locking device, a sealing device, a sealing cavity body, and a stripe nut. The locking device is arranged in the locking cavity, the sealing device is arranged in the sealing cavity body, and the locking cavity body and the sealing cavity body are locked together through a stripe nut. The utility model overcomes the shortcomings of the present medium-bore and small-bore pressure pipelines connecting method and the rigorous connecting requirements, can connect the pipelines conveniently and quickly without the support of the power supply, is pressure resistant, and can realize non-leakage fast connection in one-time application.
Description
Technical field
The utility model relate to a kind of in, the Placement of small-bore conveying liquefied gas pipeline, especially under certain pressure, can make carry liquid, gas meson in, small-bore pipeline fast, do not have leak connect in, small-bore pressure piping quick connector.
Background technique
Present known pressure piping Placement, general flange plate, the screw of adopting tightens up connection or directly welding, the enforcement rigid condition of above-mentioned Placement is to finish by the support of " electric energy ", otherwise can't implement pipeline connects, and require with implementing process tighter to professional workforce's technical ability, the careless slightly phenomenon of doing over again that promptly produces, there are steady suffering from such as bad connection and welding bead slag inclusion, pore man-hour again in waste, cause leakage, simultaneously because the high temperature that welding produces is undesirable to the rotten lining pipeline connection effect of endangering.
Summary of the invention
The purpose of this utility model is the deficiency for the condition of contact of shortcoming that overcomes existing Placement and harshness, provide a kind of in, small-bore pressure piping quick connector, it can make pipeline do not rely on power supply support under quick and convenient connection and can withstand voltage, disposable installation do not have to leak firmly and connect.
The utility model solves the problems of the technologies described above the scheme that is adopted: this pipeline quick connector comprises locking cavity, locking device, seal arrangement, seal chamber, striped nut, described locking device is arranged in the locking cavity, seal arrangement is arranged in the seal chamber, and locking cavity and seal chamber are locked by a striped nut and connected; Described locking device bigger diameter end exceeds the locking cavity, and the seal arrangement bigger diameter end exceeds seal chamber.
Described locking device is made up of external conical sleeve bigger diameter end and an O type packing ring of a longitudinal opening.
Described striped nut has half-and-half anti-, positive internal thread.
It is outer tapered that described seal arrangement is, and section is the O type.
The beneficial effects of the utility model are, during it not only makes, required connection part reached safe quick connection purpose during small-bore pressure piping connected, and thoroughly in, small-bore pressure piping power consumption connects to become does not have the power consumption connection, flange is connected the high-quality resource consumption of producing become the waste metal resource reutilization, the utility model Placement is than flange plate Placement simultaneously, save and produce consumptive material weight, simplified site operation preparatory condition that pipeline connects and facility etc., the raising work efficiency, nothing is done over again, reduce production costs and mounting cost, the dismounting that saves labor is flexible, reuses, and is handsome in appearance, rational in infrastructure, produce very easily.It not only is applicable to the quick connection of pressure piping, is applicable to that more danger, rotten pipeline and general conventional pipeline connect.Because the variation of material and filler can be worked again in making, can guarantee that the disposable nothing in ground, underground pipes road of gaseous state, liquid meson is leaked reliable the connection under high temperature and low temperature.

Embodiment
Shown in accompanying drawing 1: this pipeline quick connector comprises locking cavity 1, locking device 2, seal arrangement 3, seal chamber 4, striped nut 5, described locking device 2 is arranged in the locking cavity 1, seal arrangement 3 is arranged in the seal chamber 4, and locking cavity 1 and seal chamber 4 are locked by a striped nut 5 and connected; Described locking device 2 bigger diameter ends exceed locking cavity 1, and seal arrangement 3 bigger diameter ends exceed seal chamber 4.
Described locking device 2 is made up of external conical sleeve 6 bigger diameter ends and an O type packing ring 7 of a longitudinal opening; Also can produce packing ring 7 and opening external conical sleeve 6 bigger diameter end disjunctors, opening external conical sleeve 6 is made outer inclined butterfly wing tooth or any flute profile.
Described striped nut 5 has half-and-half anti-, positive internal thread.
It is outer tapered that described seal arrangement 3 is, and section is the O type.
During use, locking device 2 is packed in locking cavity 1 chamber, seal arrangement 3 is packed in seal chamber 4 chambeies, to lock cavity 1 and seal chamber 4 with striped nut 5 then locks and connects, the packing ring 7 of locking device 2 links to each other with the bigger diameter end of seal arrangement 3, locking cavity 1 produces relative movement with seal chamber 4 under the 5 locking effects of striped nut, shortened the distance between locking cavity 1 and the seal chamber 4, because the relative movement of locking cavity 1 and seal chamber 4, make locking device 2 and the seal arrangement in the seal chamber 43 in the locking cavity 1 produce reverse power, make the opening external conical sleeve 6 of locking device 2 under the active force of locking cavity 1, become fastening by connecting leg body 8 to internal diameter generation footpath, and seal arrangement 3 expands at dual pressurized and plays sealing effect under the effect of seal chamber 4 and be subjected to the active force of locking device 2.
The utility model can produce separately directly, the L type is curved, vertical three connect and arbitrarily angled speed connects the pressure pipe fitting.Seal arrangement adopts the external conical shape of O type section, and (or other type body, sealing tapered sleeve materials are (rubbers, mould, metallic material) that the line transportation medium that connected with connection set decides.
It is two cover unifications that the utility model is used for that straight tube connects, i.e. two seal chamber 4 disjunctor productions dorsad lock two seal chambers, 4 locks that cavity 1 and disjunctor produce to two of the sealing-locking device of packing into even respectively with two striped nuts 5.Locking device 2 is packed locking cavity 1 back under the state of not stressing, exceed locking cavity 1, seal arrangement 3 exceeds seal chamber 4, and striped nut 5 should be locking cavity 1 and more than 1 times of seal chamber 4 spacings, seal chamber in the utility model 4 directly can be connected the processing of product disjunctor with pipeline, the seal arrangement 3 of packing into connects (chew as valve, water etc.) with will pack into the locking cavity 1 of locking device 2 of striped nut 5 then, can become novel pressure pipeline speed by-product.
