Abstract
The utility model relates to an unloading crane-form pipe for railway tank trucks, which is characterized in that a fast coupling (2) is provided at the front end of the opening of the unloading crane-form pipe in the utility model; the fast coupling (2) is connected to a locking fast coupling (3); the locking fast coupling (3) is connected to a metal corrugated pipe (5); the metal corrugated tube (5) is connected with a metal oil tube (6) via a flange; the front end of the metal oil tube (6) can be connected to a rotary coupling (7), or a rotary metal tube (8), or a bottom-terminal rotary coupling (9), or an O shaped sealing ring (10) according to needs.
Description
Technical field:
The utility model relates to rail tank car transportation technology field, unloads oil filling riser under a kind of rail tank car.
Background technology:
At present, the oil pipeline of existing petrochemical industry railway trestle loading and unloading oil product is made up of an oil proof rubber pipe, two simple steel flanges basically, and India rubber tube is connected with the main line of trestle and the loading and unloading joint of tank car respectively, finishes oil transportation work.The weak point of this structure is that India rubber tube can not conduct electricity, and, can't eliminate as producing static in the oil transportation process, and flashing causes fire when serious; Secondly, this oil resisting rubber hose, simple steel flange structure heaviness connect trouble, and the transport pipe butt joint is wasted time and energy, and is difficult to enhance productivity.
Summary of the invention:
Add simple steel flange to unloading the deficiency of oil transportation under the railway oil tank for overcoming existing oil proof rubber pipe, the utility model provides under a kind of new rail tank car and unloads oil filling riser, and this device adopts metal oil pipeline structure, and its no generation of static electricity moves flexibly, and is easy to connect quick.
The utility model adopts following technical scheme to realize the foregoing invention purpose;
The following oil filling riser that unloads of described railway trestle truck tanker, its front end that unloads the oil filling riser mouth down has a quick coupling, and what dock with this quick coupling is lock-bit quick coupling; What be connected with lock-bit quick coupling is metal bellow, and metal bellow is connected with metal oil conduit by flange, and the front end of metal oil conduit can connect swivel joint as required, rotating metallic pipe, lower port swivel joint and " O " RunddichtringO.
The lock-bit quick coupling that the following quick coupling of unloading oil filling riser of described railway trestle truck tanker is inserted mutually, it has a clamp handle, and has tightening seal washer.
The following metal bellow that unloads oil filling riser of described railway trestle truck tanker is connected with metal oil conduit by Lan Fa, and it has tightening seal washer.
The following swivel joint of unloading oil filling riser of described railway trestle truck tanker, it has backbone sealing ring, and the steel ball ball is arranged between swivel joint inner core and the housing, " O " RunddichtringO.
Owing to adopt technique scheme, the utlity model has following preceence:
1, metallic conduit can be eliminated the static that produces when oil product flows, and guarantees safety.
2, metal bellow can realize that the retractility contraposition connects, and accurately fast, light weight reduces labour intensity flexibly.
3, metallic quick coupling is pegged graft conveniently, can locate lockedly, increases work efficiency, and guarantees safety.
4, the spinner joint adopts the three seals measure, guarantees sealing effectiveness, improves service life.
