Abstract
Provided is a link structure for angle door block at rail route vehicle end, the structure is characterized in that, the structure comprises a weld flange, a transition joint, a fix flange, a double head screw pillar, a flat pad ring, a spring pad ring, a screw nut, the weld flange and the vehicle end main pipe route adopt a weld structure to connect, the transition joint is located in the middle of the weld flange and the fix flange, through the double head screw pillar, the flat pad ring, the spring pad ring and the screw nut connect with the fix flange, the transition joint and the weld flange, the transition joint and the bend angle door block connect through a screw spiral line. The structure takes the fitting surface of the transition joint and the weld flange and the fix flange as plane surface and cylinder surface, adjusts the angle freely along with the transition joint of the bend angle door block during installation, turns the bend angle door block to a devised angle, the double head screw pillar is used coordinately with the flat pad ring, the spring pad ring and the screw nut, through the moment of force pretensions, and prevents loosening and installs readily.
Description
Technical field
The invention belongs to technical field of rail traffic, especially relate to a kind of car end used for rail vehicle angle cock and connect knot
Structure.
Background technology
Rail vehicle is provided with angle cock at car end train pipe and blast main, when for some reason（As being in train
Afterbody, train solution are compiled or are tested）The compressed air blocked in train pipe and blast main is needed to supply seasonable, can be by operating knuckle plug
Door is realized.The attachment structure of angle cock should easy for installation, prevent from getting loose.
The angle cock of China's railway vehicle end and train pipe and blast main are all using screw connection structure.Using screw thread
Attachment structure, the very difficult adjustment of angle cock setting angle when mounted, it is not easy to install；In use as threaded pine
De-, there is the risk that leakage occurs.
Content of the invention
The technical problem to be solved is to design a kind of attachment structure of angle cock so that angle cock is installed
Easy, be difficult to get loose.
For solving above-mentioned technical problem, the present invention provides a kind of car end used for rail vehicle its feature of angle cock attachment structure
It is：Including welded flange, transit joint, mounting flange, studs, plain washer, spring washer, nut, welded flange with
Car end main line adopts welding structure to connect, and transit joint is located between welded flange and mounting flange, by studs, puts down
Mounting flange, transit joint and welded flange are linked together by packing ring, spring washer and nut, transit joint and angle cock
It is threaded connection.
The present invention is plane and the face of cylinder due to the mating surface of transit joint and welded flange and mounting flange, so in peace
During dress, angle cock can make angle cock be in the angle of design, studs and plain cushion with the arbitrarily angled adjustment of transit joint
Circle, spring washer and nut screw connection use, and by moment pretension, can prevent from getting loose, easy for installation.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the B direction view of Fig. 1；
Fig. 3 is the sectional view of the line A-A along along Fig. 1.
Specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the specific embodiment of the invention include car end main line welded flange 1, transit joint 2,
Mounting flange 3, studs 4, plain washer 5, spring washer 6, nut 7, I sealing ring 8 and II sealing ring 9 form.Welded flange
It is connected using welding structure with car end main line 11.Transit joint 2 is located between welded flange and mounting flange, by double end spiral shell
Mounting flange 3, transit joint 2 and welded flange 1 can be linked together by post 4, plain washer 5, spring washer 6 and nut 7.Transition
Joint 2 and angle cock are threaded connection.I sealing ring 8 and II sealing ring 9 seal.Due to transit joint 2 and welding
The mating surface of flange 1 and mounting flange 3 is plane and the face of cylinder, so when mounted, angle cock 10 can be with transit joint 2
Meaning angle adjustment makes angle cock be in the angle of design.Studs 4 is made with the cooperation of plain washer 5, spring washer 6 and nut 7
With by moment pretension, preventing from getting loose.
