Description
Technical field
The present invention relates to a kind of pipe joint, particularly a kind of rapid pipe joint that is used for connecting the corrugated flexible metal tube that is used to carry gas-liquid.
Background technique
The mode of traditional gas appliances such as connection LP gas cylinder, fuel tube or gas cooker is: tighten with Drop-proof with galvanized wire by the rubber pipe connection and at the two ends of rubber pipe; This Placement exists many defectives: install and transposing inconvenience, under bending state, block gas circuit easily, the rubber pipe corrosion-resistant, easily aging, working life is short, gas leak phenomenon takes place easily, just because of this, explosive incident is revealed in the annual gas poisoning or the combustion gas that all can take place to cause because of above-mentioned reason in all parts of the country.
For solving the safe and reliable connectivity problem of gas pipeline, it is to be processed into the soft connecting tube with helical fissure metal tube that " the helical fissure metal hose connector " of our formerly Chinese utility model patent ZL97225276.2 number " plug-in type helical fissure metal hose connector ", ZL97225278.9 number and ZL01211062.0 number " a kind of modified model metallic hose " disclose three kinds of main bodys, and its two ends are welded with the thread connecting joint of metal; These three kinds of design proposals are owing to adopted the corrugated metal tube body, have certain flexible can be arbitrarily crooked and don't can bend, and it is convenient and reliable to be threaded, can thoroughly stop gas leakage, choke phenomenon, thereby eliminate because of combustion gas and reveal the accident potential that causes poisoning, explosive incident, practical effect is fine.
But, because in above-mentioned three kinds of technological schemes, the termination of corrugated flexible metal tube main body all must be welded with a metal joint, this just limits its length dimension, in case when dispatching from the factory, determine just can't change, more can't carry out freely reducing according to Len req at the scene.And existing various pipe joint is all at metal tube, plastic tube or composite pipe design, and not seeing has specially at the corrugated flexible metal tube design.For this reason, " a kind of rapid pipe joint that is used for corrugated flexible metal tube " that our Chinese invention patent formerly is ZL03129320.4 number discloses a kind of rapid pipe joint that can be used to free-hand connection corrugated flexible metal tube, this rapid pipe joint includes a joint body, it has one can hold the jack that corrugated flexible metal tube inserts from back to front, in this jack, be disposed with the profile of tooth dog collar vertically from front to back, seal ring and clamping sleeve, wherein the front-end face of profile of tooth dog collar is spacing by the step institute that the body jack is provided with in the corresponding part, the rear portion outer circumferential face that it is characterized in that described clamping sleeve is the conical surface shape that shrinks gradually, and include a stop collar that inserts from back to front in the body jack, its front inner wall has the conical surface that matches with described clamping sleeve rear portion periphery, the jack inwall relative fixed of its outer wall and body.This technological scheme has solved the difficult problem of the elongated degree corrugated flexible metal tube of on-the-spot installation main body effectively, and rapid pipe joint is quite reliable with being connected of corrugated flexible metal tube main body, even exert oneself the drawing corrugated flexible metal tube, also is difficult to pull; But, find that through practice because the side face sealing means that this technological scheme adopts, sealing effect is desirable not enough.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sealing effect better to be used for the rapid pipe joint of corrugated flexible metal tube at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: this rapid pipe joint that is used for corrugated flexible metal tube includes a joint body, this joint body has one can hold the jack that corrugated flexible metal tube inserts from back to front, it is characterized in that also including the sleeve that is screwed onto in the front end in the joint body jack afterbody, and the front end at this sleeve also is connected with the clamping sleeve that a front end has closing in portion, and the jack of described joint body has interior omoplate to position that should the clamping sleeve front end, and omoplate is provided with a ring packing plain cushion in this.
In corrugated flexible metal tube inserts the jack that sleeve inserts joint body then from back to front, ring packing plain cushion in the contiguous jack of corrugated flexible metal tube, at this moment, the front end closing in portion of clamping sleeve be inlay card on the node of the corrugated flexible metal tube of correspondence, thereby realize being connected between rapid pipe joint and the corrugated flexible metal tube; Then, the turn sleeve makes the reach of its opposing tabs body, and clamping sleeve promptly promotes corrugated flexible metal tube by its front end closing in portion and continues reach, until being tight against described ring packing plain cushion, thereby realizes end face seal.
Described clamping sleeve is good to adopt existing certain rigidity that certain flexible material is arranged again, for the consideration on the manufacture cost, can realize by embed metalwork on working of plastics.
Placement between described clamping sleeve and the described sleeve can adopt various prior aries, can be simply annular groove be set at the afterbody outer wall of clamping sleeve, and annular groove also being set in the front inner wall of sleeve, two grooves fasten mutually and connect one.
Be connected more firmly between the node for the front end closing in portion that makes clamping sleeve and corrugated flexible metal tube, described joint body omoplate position afterwards within it has the conical surface portion of expansion backward, like this, when the closing in portion of clamping sleeve moves forward to this conical surface portion, will receive the extruding of this conical surface portion and more tightly inlay card on the node of corrugated flexible metal tube; And for further enhanced leaktightness effect, the position after joint body is positioned at the ring packing plain cushion, before the conical surface portion is equipped with an O RunddichtringO, constitutes another sealing with the clamping sleeve front end that puts in place with reach.
In order to guarantee to dispatch from the factory when assembling, reason does not screw sleeve prematurely and influences and be connected with joint body, and described sleeve afterbody can have a flange, and snaps in an expanding ring between the rear end of this flange and joint body; And for further sealing, also can a sheathed O RunddichtringO before the tail flange of described sleeve, so as when sleeve opposing tabs body rotation reach with the rear end of joint body between another sealing of formation.
For the corrugated flexible metal tube that is with protecting cover outward, when connecting, its front end must be removed the part protecting cover, the length of exposed portions serve is positioned at clamping sleeve before for good to correct before inserting afterwards, like this, and after connection, the sleeve afterbody can be pressed on the periphery of protecting cover simultaneously, plays seal action better; In order further to strengthen sealing effect, also can be embedded a seal ring at the afterbody inwall place of sleeve, with and the outer wall (protecting cover) of corrugated flexible metal tube between form another sealing, also therefore limited the radially movable of corrugated flexible metal tube simultaneously.
The front end of described body can be designed to existing various connecting head form, and be threaded being used for as carving, or be designed to the link type being used for the sleeve rubber pipe with outside thread, or the like.
Compared with prior art, the present invention has substituted all face seals by end face seal, and sealing effect is strengthened greatly, and more additional seal means have further been strengthened sealing effect again.
