Abstract
The utility model relates to a pipe joint, which comprises a pipe connecting portion, a valve connecting portion, an annular groove and an elastic ring, wherein the pipe connecting portion is arranged on one side of the pipe joint, the valve connecting portion is arranged on the other side of the pipe joint, the annular groove is arranged on the valve connecting portion, the elastic ring is embedded in the annular groove, and the outer surface of the elastic ring is protruded from the outer surface of the valve connecting portion. The pipe joint can be sealed by means of deformation of the elastic ring and close sealing fit of a socked joint body, so that the problem that conventional pipe joints are easy to be in gas leakage is solved. Meanwhile, the pipe joint is easy to assemble and has low requirement on part processing precision, and accordingly processing cost of the pipe joint is low.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of airbrake hose joint.
Background technique
Medium-sized or above lorry or passenger vehicle that China produces generally all adopt Pneumatic braking system, and pipe joint is the vitals that connects each element of Pneumatic braking system.At present being connected between automobile pressure braking system flexible pipe and the air brake valve adopted the FERRULETYPE joint more, seals by the hose coupling conical surface and FERRULETYPE fittings body cone match.For example Chinese patent ZL200720029524.9 discloses a kind of air-brake gladhand, and with reference to figure 1, this air-brake gladhand one side is the flexible pipe grafting part 2 that is provided with three teeth of falling the rifle 1, and opposite side is valve attachment portion 3.This pipe joint structure tolerance is not good, very easily because the machining accuracy error of pipe joint cause poor sealing and leak gas, can only be by improving machining accuracy, guaranteeing enough screw-down torques even be coated with sealer to solve sealing problem, leak rate height, technology cost height.
Problem at the aforementioned tube joint exists the utility model proposes a kind of new pipe joint.
The model utility content
Main purpose of the present utility model is to provide a kind of pipe joint, and this pipe joint can guarantee the excellent sealing of pipeline.
For achieving the above object, the utility model has been taked following technological scheme:
A kind of pipe joint comprises: pipe jointing part is positioned at described pipe joint one side; The valve joint is positioned at described pipe joint opposite side; And Sealing, being located on described valve joint, the sealing part seals between described valve joint and fittings body.
Further, described Sealing is an elastic ring body.
Further, also be provided with annular groove on the described valve joint, described elastic ring body is embedded in the described annular groove, and the outer surface of described elastic ring body protrudes in the outer surface of described valve joint.
Further, described valve joint is a conical surface body.
Further, described valve joint is a spherical surface body.
Further, pipe joint of the present utility model also comprises first fastening unit, is arranged at the outside of described valve joint, is used for described valve joint and fittings body are tightened together.
Further, described first fastening unit is a nut.
Further, pipe joint of the present utility model also comprises second fastening unit, is arranged at described pipe jointing part outside, is used for described pipe jointing part and flexible pipe are tightened together.
Further, described second fastening unit is the iron cover.
The utility model pipe joint is provided with Sealing at its valve joint, specifically, be to be provided with annular groove at the valve joint, in annular groove, be embedded elastic ring body and make the outer surface of this elastic ring body protrude in the outer surface of its valve joint, therefore, when this pipe joint with after the FERRULETYPE fittings body is connected, can closely cooperate and reach sealing by the distortion of this elastic ring body and FERRULETYPE fittings body, thereby solve the easily problem of gas leakage of conventional pipe joint.Simultaneously, the utility model pipe joint is easy to assembling, do not require very high part processing precision, so the technology cost is low.
Description of drawings
By description, will make that the technical solution of the utility model and advantage thereof are apparent below in conjunction with accompanying drawing to the utility model preferred embodiment.
Fig. 1 is the partial sectional view of prior art air-brake gladhand;
Fig. 2 is the utility model pipe joint one embodiment's a partial sectional view;
Fig. 3 is another embodiment's of the utility model pipe joint a partial sectional view;
Fig. 4 is the utility model pipe joint one embodiment's an assembly structure schematic representation;
Fig. 5 is another embodiment's of the utility model pipe joint an assembly structure schematic representation.
Embodiment
Below by specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail.Yet should be appreciated that the element of Miao Shuing, structure and feature also can be attached among other embodiment valuably in one embodiment under the situation that does not have further narration.
Fig. 2 is the partial sectional view of the utility model pipe joint one preferred embodiment, and this pipe joint comprises: pipe jointing part 21 is positioned at this pipe joint one side; Valve joint 23 is positioned at this pipe joint opposite side, and this valve joint 23 is a conical surface body; Annular groove 25 is arranged on the valve joint 23; Elastic ring body 27 (Fig. 1 is not shown) is embedded in the annular groove 25, and the outer surface of this elastic ring body 27 protrudes in valve joint 23 outer surfaces.
Fig. 3 is the partial sectional view of another preferred embodiment of the utility model pipe joint, and the difference of this pipe joint and last embodiment's pipe joint is that its valve joint 23 is a spherical surface body, and all the other structures are with last embodiment's pipe joint.
With reference to figure 4, in use, the utility model pipe joint 20 is connected with FERRULETYPE fittings body 52 by bite type tube nut 50 usefulness screw threads, the conical surface of valve joint 23 inserts in the taper hole of FERRULETYPE fittings body 52, closely cooperate and seal by the taper hole of the distortion of elastic ring body 27 and FERRULETYPE fittings body 52, pipe jointing part 21 overlaps 62 rivetings together with flexible pipe 60 by iron, and the other end of iron cover 62 is connected with the automobile brake pipeline.
With reference to figure 5, understand ground easily, when this valve joint 23 is spherical surface body, during use, the sphere of this valve joint 23 inserts in the taper hole of this FERRULETYPE fittings body 52, closely cooperates and seals by the taper hole of the distortion of elastic ring body 27 and FERRULETYPE fittings body 52, and the difference during with last embodiment's pipe joint use is, its valve joint 23 forms linear sealing with the taper hole of FERRULETYPE fittings body 52, and all the other structures are with last embodiment's pipe joint.
The pipeline that the utility model pipe joint not only can be used for the Automobile air braking system connects, and the pipeline that also can be used for the automobile power steering hydraulic system connects, and the pipe joint of two systems uses assembly method similar, does not repeat them here.
The utility model pipe joint is provided with annular groove at its valve joint, in annular groove, be embedded elastic ring body and make the outer surface of this elastic ring body protrude in the outer surface of its valve joint, therefore, when this pipe joint with after the FERRULETYPE fittings body is connected, can closely cooperate and reach sealing by the distortion of this elastic ring body and FERRULETYPE fittings body, thereby solve the easily problem of gas leakage of conventional pipe joint.Simultaneously, the utility model pipe joint is easy to assembling, do not require very high part processing precision, so the technology cost is low.
