Abstract
The invention discloses a clamp protruding connecting tube, including a connecting piece body, a connecting nut, the end of the connecting piece body is provided with an external thread adaptive with the connecting nut, the connecting nut is provided with a limiting wall matching with the protruding ring of the protruding circular canal at the inner side of the inner thread, characterized in that, the annular cavity is provided with a fixing step on the outside wall relative to the elastic sealing ring. The invention has the advantage that, through the fixing step on the outside wall relative to the elastic sealing ring, the problem that the elastic sealing ring is over pressed or not enough by the protruding circular canal is solved, which makes the sealing of the product even better, and the service longer.
Description
Technical field
The present invention relates to a kind of conduit coupling, specifically be meant clip convex type pipeline joint component.
Background technology
Common pipe fitting connected mode has clamp-press type, the ring pressure type, the flange formula, bonded, carry screw-type, spigot-and-socket, the socket weld formula, the scrobicular ring formula, clamping hoop type, bolt-type, loose joint formula flange connects, welded type, block connected modes such as protruding, wherein the card convex type connected mode constitutes and presses ring fastening type and cooperate by waiting to connect bulge loop pipe and conduit coupling, be called for short " card convex type connection method ", it is good to have secure seal, erecting tools is lightly simple and easy, there is not electric noiseless action, low price, install and connect advantages such as efficient and convenient, solve conventional pipelines and connect the site operation difficulty, daily change safeguards that limitation is big, to workmen's specification requirement height, assembling connects difficulty rapidly, the on-the-spot instability that connects, be subjected to environment for use to influence installation quality or the like technical problem, therefore become the technique direction that industry is promoted mainly, be particularly suitable for the connection of thin-wall stainless steel pipe fitting.
Current, its structure of existing clip convex type pipeline joint component is: comprise the connector body, and form the attaching nut be threaded and cooperate with the connector body, the inwall of described nut is provided with and waits to connect the limited wall that the bulge loop card of bulge loop pipe is joined, and the end inwall of connector body is provided with annular cavity, on this cavity elastic sealing ring is installed, when it connects, wait to connect the bulge loop pipe and pass nut, the attaching nut is screwedly mounted on the connector body then, wait that bulge loop one side that connects the bulge loop pipe is connected on attaching nut's the limited wall this moment, opposite side forms at the crush seal ring and is fixed with sealing, but this clip convex type pipeline joint component is under the different temperatures situation, the situation of expanding with heat and contract with cold will inevitably appear, perhaps overtighten or loosening because of screw thread, thereby cause the closure size of standard configuration owing to expand with heat and contract with cold etc. former thereby cause the bulge loop pipe not enough, thereby cause product the problem that sealing descends to occur elastic seal ring excessive compression or extruding.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming and defect of prior art, and a kind of clip convex type pipeline joint component of simple in structure, easy to process, good sealing effect is provided.
For achieving the above object, technical scheme of the present invention is, comprise connector body, attaching nut, the lateral wall of the end of this connector body is provided with the screw thread adaptive with the attaching nut, the axial inboard of relative its inner thread of described attaching nut is provided with and waits to connect the limited wall that the bulge loop card of bulge loop pipe is joined, the end madial wall of described connector body is provided with annular cavity, this annular cavity is provided with elastic sealing ring, and the chamber wall in the outside of the relative resilient sealing ring of described annular cavity is provided with and waits to connect the positioning step that the bulge loop card of bulge loop pipe is joined.By this setting, wait that the bulge loop two ends that connect the bulge loop pipe are positioned at respectively on limited wall and the positioning step, prevented to expand with heat and contract with cold and connector body and attaching nut's thread looseness or tension and cause elastic sealing ring insufficient compression or excess compression situation, improved the sealing stability and the service life of elastic seal ring.
Further be provided with is that described attaching nut's the inboard of relative its inner thread is provided with the positive stop end with the termination butt of connector body.Because waiting to connect the bulge loop pipe is generally thin-wall stainless steel, therefore its bulge loop still might because of the connector body and the attaching nut is overtighten deforms, thereby cause elastic sealing ring decrement instability, make product hermeticity descend, and by this setting, connector body and attaching nut's the maximum amount of being screwed into is limited, improved the stability of sealing ring compression, improved the sealing property of product.
Further being provided with is to be provided with the locking thread packing ring between described connector body and the attaching nut.
Further being provided with is that described connector body is a straight pipe connector body, and this is provided with can also be that described connector body is a bend pipe connector body; This is provided with can also be that described connector body is a three-way pipe connector body.
The invention has the advantages that: the chamber wall in the outside of the relative resilient sealing ring by annular cavity is provided with and waits to connect the positioning step that the bulge loop card of bulge loop pipe is joined, prevent that elastic sealing ring is by the problem of being waited to connect bulge loop pipe excessive compression or extruding deficiency and bringing sealing to descend, make that the sealing effectiveness of product is better, the elastic sealing ring longer service life.
