Description
Technical field
Negative and positive soft or hard two seal structures fittings body, relates to auto brake system pipeline field.
Background technique
Under prior art, on automobile and train straight air brake system pipeline and fittings body connect sealing configuration be substantially all together with sealed type, and most be FERRULETYPE sealing configuration.As shown in Figure 3, such sealing cone body structure that cooperatively interacts is all that rigidity seals firmly.If the joint conical surface has cut or lose circle phenomenon, or nylon hose loses circle and wall unevenness all may cause gas circuit compressed air to leak gas to guest performer.Cause automobile and whole train Brake System air pipe poor sealing performance, thus make gas receiver and air pipe air pressure decline numerical value greatly, cause postponing time of departure next day, and increase fuel oil spending, cause the blowdown of air to protect simultaneously.Time serious, also can there is degradation defect under braking force, thus form potential safety hazard.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides one to realize double seal, improves the negative and positive soft or hard two seal structures fittings body of automobile and whole train Brake System air pipe sealability and braking force.
The utility model solves the technological scheme that its technical problem adopts: this negative and positive soft or hard two seal structures fittings body, comprise negative joint and male connector that center has through hole, described male connector is offer near left end end circumference can the sealed groove of mounting O-shaped seal ring, on the right side of sealed groove, circumference is provided with the outer centrum of outwardly convex, and male connector right-hand member is provided with can the pagoda joint of connecting hose;
Described negative joint right-hand member has the circular hole that can hold male connector left end portion, and circular hole end is provided with conical bore; Male connector left end inserts in the circular hole of negative joint right-hand member, and O RunddichtringO seals with circular-hole internal-wall and connects, and negative joint outer ring and retaining ring link together, and retaining ring makes conical bore seal with outer centrum to connect.O RunddichtringO and negative joint realize soft seal and are connected, and outer centrum and negative joint realize firmly being tightly connected, and realize double seal, improve automobile and whole train braking system air pipe sealability.
Described retaining ring is attaching nut, and described negative joint outer ring is provided with outside thread, and retaining ring is threaded with negative joint.Be threaded and make assembling fast and flexible and can be for convenience detach.
The sectional shape of described outer centrum is the bevelled trapezoid shaped of the equal tool in the left and right sides, described retaining ring end has back-up ring, back-up ring inner ring is provided with a circle conical seal (contact) face, and on the left of outer centrum, inclined-plane seals with conical bore and connects, and on the right side of outer centrum, inclined-plane seals with conical seal (contact) face and connects.Outer centrum both sides army crosses and realizes sealing, and sealing effect is higher.
Compared with prior art, the beneficial effect that the technique scheme of this negative and positive soft or hard two seal structures fittings body has is:
1, O RunddichtringO and negative joint realize soft seal and are connected, and outer centrum and negative joint realize firmly being tightly connected, and realize double seal, improve automobile and whole train braking system air pipe sealability, prevent braking force from declining, raising vehicle safety performance.
2, owing to improve automobile and whole train Brake System air pipe sealability, as long as so the engine start when next day dispatches a car of automobile and train, can dispatch a car, thoroughly solve gas receiver and the air pipe large phenomenon of air pressure decline numerical value overnight that joint under prior art causes because of poor sealing performance, the time preventing postponing next day and dispatch a car; And the blowdown of saving fuel oil spending and decreasing air, protects environment.

Embodiment
Fig. 1 ~ 2 are most preferred embodiments of the present utility model, are described further below in conjunction with accompanying drawing 1 ~ 3 pair of the utility model.
With reference to accompanying drawing 1,2: negative and positive soft or hard two seal structures fittings body, comprises negative joint 1 and male connector 3 that center has through hole.Negative joint 1 i.e. socket connector, male connector 3 i.e. pin connectors.Male connector 3 is offer near left end end circumference can the sealed groove 301 of mounting O-shaped seal ring 2, and on the right side of sealed groove 301, circumference is provided with the outer centrum 302 of outwardly convex, and male connector 3 right-hand member is provided with can the pagoda joint 303 of connecting hose 4.Pagoda joint 303 connecting hose 4.
Negative joint 1 right-hand member has the circular hole that can hold male connector 3 left end portion, and circular hole end is provided with conical bore 101; Male connector 3 left end inserts in the circular hole of negative joint 1 right-hand member, and O RunddichtringO 2 seals with circular-hole internal-wall and connects, and negative joint 1 outer ring and retaining ring 5 link together, and retaining ring 5 makes conical bore 101 seal with outer centrum 302 to connect.Retaining ring 5 is attaching nut, and negative joint 1 outer ring is provided with outside thread, and retaining ring 5 is threaded with negative joint 1.The sectional shape of outer centrum 302 is the bevelled trapezoid shaped of the equal tool in the left and right sides, described retaining ring 5 end has back-up ring, back-up ring inner ring is provided with a circle conical seal (contact) face 501, on the left of outer centrum 302, inclined-plane seals with conical bore 101 and connects, and on the right side of outer centrum 302, inclined-plane seals with conical seal (contact) face 501 and connects.
As shown in Figure 3, on the automobile under prior art and train straight air brake system pipeline and fittings body connect sealing configuration be together with sealed type, and adopt FERRULETYPE to connect sealing, this sealing cone body structure that cooperatively interacts is all that rigidity seals firmly.If the conical surface of fittings body 6 or cutting ferrule 7 has scratching, lose the features such as circle, or nylon hose loses the feature such as circle, wall unevenness and all easily causes gas circuit compressed air to leak gas to guest performer, cause degradation defect under automobile and whole train Brake System air pipe poor sealing performance braking force.
And this negative and positive soft or hard two seal structures fittings body has soft or hard two seal structures, its principle is: when O RunddichtringO 2 and circular-hole internal-wall sealing place occurs going here and there leak gas time, the hard sealing that conical bore 101 and outer centrum 302 seal connecting part still keeps closed state.Otherwise hard sealing that conical bore 101 and outer centrum 302 seal connecting part occurs going here and there when leaking gas, when O RunddichtringO 2 and circular-hole internal-wall sealing place still keep closed state, therefore substantially increase automobile and whole train Brake System air pipe sealability and braking force.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
