A kind of car end angle cock attachment structure used for rail vehicle, it is characterised in that：Including welded flange, transit joint, mounting flange, studs, plain washer, spring washer, nut, welded flange is connected with car end main line using welding structure, transit joint is located between welded flange and mounting flange, mounting flange, transit joint and welded flange are linked together by studs, plain washer, spring washer and nut, transit joint is connected through a screw thread with angle cock.The utility model is plane and the face of cylinder due to the mating surface of transit joint and welded flange and mounting flange, so angle cock can be adjusted with transit joint any angle when mounted, angle cock is set to be in the angle of design, studs, use cooperatively with plain washer, spring washer and nut, pass through torque pretension, it can prevent from releasing, it is easy for installation.
Description
Technical field
The utility model belongs to technical field of rail traffic, connects more particularly, to a kind of car end used for rail vehicle angle cock
Binding structure.
Background technology
Rail vehicle is provided with angle cock at car end train pipe and blast main, when for some reason（Such as it is in train
Afterbody, train solution are compiled or tested）, can be by operating knuckle plug when needing to block the compressed air supply in train pipe and blast main
Door is realized.The attachment structure of angle cock should it is easy for installation, prevent from releasing.
The angle cock of China's railway vehicle end uses screw connection structure with train pipe and blast main.Using screw thread
Attachment structure, angle cock setting angle is difficult adjustment when mounted, is not easy to install；In use as being threadedly coupled pine
It is de-, there is the risk leaked.
Utility model content
Technical problem to be solved in the utility model is to design a kind of attachment structure of angle cock so that angle cock
Simple installation, it is difficult to release.
In order to solve the above technical problems, the utility model provide a kind of car end angle cock attachment structure used for rail vehicle its
It is characterised by：Including welded flange, transit joint, mounting flange, studs, plain washer, spring washer, nut, welding
Orchid is connected with car end main line using welding structure, and transit joint is located between welded flange and mounting flange, passes through double end spiral shell
Post, plain washer, spring washer and nut link together mounting flange, transit joint and welded flange, transit joint and folding
Angle cock is connected through a screw thread.
The utility model is plane and the face of cylinder due to the mating surface of transit joint and welded flange and mounting flange, so
Angle cock can be adjusted with transit joint any angle when mounted, make angle cock be in design angle, studs, with
Plain washer, spring washer and nut are used cooperatively, by torque pretension, can prevent from releasing, easy for installation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 B direction views；
Fig. 3 is the sectional view of the line A-A along along Fig. 1.
Embodiment
Reference picture 1, Fig. 2, Fig. 3, the utility model embodiment include car end main line welded flange 1, transition and connect
First 2, mounting flange 3, studs 4, plain washer 5, spring washer 6, nut 7, I sealing rings 8 and II sealing rings 9 are constituted.Welding
Flange is connected with car end main line 11 using welding structure.Transit joint 2 is located between welded flange and mounting flange, by double
Header stud 4, plain washer 5, spring washer 6 and nut 7 can link together mounting flange 3, transit joint 2 and welded flange 1.
Transit joint 2 is connected through a screw thread with angle cock.I sealing rings 8 and II sealing rings 9 seal.Due to transit joint 2 with
The mating surface of welded flange 1 and mounting flange 3 is plane and the face of cylinder, so when mounted, angle cock 10 can connect with transition
First 2 any angle adjustment makes angle cock be in the angle designed.Studs 4 and plain washer 5, spring washer 6 and nut 7
Use cooperatively, by torque pretension, can prevent from releasing.
