Abstract
The utility model discloses a leakage-proof mechanical sleeve, which consists of a main body and a main body nut, wherein the lower end of the main body nut is provided with external threads, and internal threads arranged on the sleeve main body are matched with the external threads. The leakage-proof mechanical sleeve is characterized in that the threaded end of the external threads of the main body nut is provided with a boss which is used for mounting a retainer ring, the upper end of the sleeve main body is provided with a boss which is provided with a sealing gasket, and after the external threads of the main body nut are matched with the internal threads of the sleeve main body, the retainer ring is abutted against the sealing gasket. The leakage-proof mechanical sleeve adopts a plane sealing manner and seals through contacting with the whole surface, so that the sealing manner is simple and good in effect, the safer sealing performance of pipes and pipe fittings is improved, and the coefficient of compressibility of the sealing gasket and the pipe fittings is designed. The sealing gasket is fully guaranteed to normally work and be normally used under the condition of expansion caused by heat and contraction caused by cold, the conditions that the sealing gasket is deadly pressed or be subjected to compressive strain and the like are avoided when the sealing gasket inside the leakage-proof mechanical sleeve and a corrugated pipe are connected, the use safety of the leakage-proof mechanical sleeve is improved, and the service life of the leakage-proof mechanical sleeve is long.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates to concretely the mechanical sleeve that a kind of rock gas pipe fitting connects anti-leak.
Background technique
Development due to modern industry, Household gas pipeline is progressively used < < combustion gas to carry with stainless steel ripple flexible pipe and pipe fitting > > replacement now, allow huge numbers of families use novel energy pipeline and the accessory of safer environmental protection, this product is promoted the use of now at home on a large scale, in use also progressively expose the defect that indivedual auxiliary products exist, also existing must be potential safety hazard simultaneously.
In the machinery sleeve of anti-leak in the past and stainless steel ripple flexible pipe Placement, initial stainless steel ripple flexible pipe is connected with anti-leak machinery sleeve the card edge type adopting, but what internal structure and corrugated stainless steel tubing joint adopted is plastics packings, utilize the main ripple of plastics toughness card, sealing means and to be a point go many places sealing as support, sealing means is also complicated.In using process as occur slight twisting, just may cause tubing and pipe fitting joint to occur gas leakage phenomenon, the time use long plastics packing will be progressively aging with lose toughness, the while also there will be the potential safety hazard of gas leakage.
Therefore, for above problem, be necessary that the structure of carrying out pipeline junction improves, to ensure rock gas safe handling.
Model utility content
The problem existing for above-mentioned prior art, the utility model provides a kind of anti-leak machinery sleeve, the problem that before solving, the sealed member life-span is short, sealing effect is poor, guarantee sealing gasket normal work use in the situation of expanding with heat and contract with cold, the sealing gasket of anti-leak machinery sleeve inner there will not be sealing gasket to kill while being connected with bellows, the situations such as compressive strain have also improved sealing gasket working life simultaneously, improve anti-leak machinery sleeve and use safety and long characteristic of life-span.
The technical solution of the utility model is: a kind of anti-leak machinery sleeve, comprise sleeve body and main body nut, main body nut lower end has outside thread, what coordinate with outside thread is the internal thread that sleeve body arranges, it is characterized in that: in main body nut male end, be provided with boss, described boss is used for installing collar, described sleeve body upper end is provided with boss, on boss, be provided with sealing gasket, after main body nut outside thread and sleeve body screw-internal thread fit, collar and sealing gasket face face connect.
Further, described collar is provided with boss structure, and boss end is by main body nut upper end.This structure is mainly in order to allow boss and bellows butt, limits it and proceeds mobile.
Further, described sealing gasket is the Gask-O-Seal of cylindricality.This structure principal security sealing is lined with enough compression rebound effects, guarantees that it frequently uses.
Further, be also provided with the annular wall of indent on described main body nut inwall, described annular wall is used for installing seal ring, and described seal ring has the bump protruding towards main body nut center.This structure is mainly used for installing seal ring and makes seal ring and bellows carries out fitted seal Leakage prevention.
Further, the outer ripple conformal of described bump and bellows.Further guarantee the good fit of seal ring bump and bellows, reach better sealing effect.
Further, the height of described sealing gasket is higher than the boss height of sleeve body upper end.This structure is exactly at main body nut, to coordinate rear collar and sealing gasket there is no butt and leak from screw-thread fit with sleeve body in order to prevent.
Further, under the screw thread not-go-end of described sleeve body female end, be also provided with the boss that is greater than sealing gasket external diameter.One space is set at this place is convenient to main body nut to be that sleeve body coordinates stepping down of rear thread end.
The beneficial effects of the utility model are: the utility model adopts by adopting plane sealing mode, with whole contact, seal, sealing means simple effects is good, improves the safer sealing of tubing and pipe fitting, and has designed the compressibility coefficient of sealing gasket and pipe fitting.Fully guarantee sealing gasket normal work use in the situation of expanding with heat and contract with cold, the sealing gasket of anti-leak machinery sleeve inner there will not be sealing gasket to kill while being connected with bellows, the situations such as compressive strain, also improved sealing gasket working life simultaneously, improved anti-leak machinery sleeve and use safety and long characteristic of life-span.
