Tank car joint

Abstract

The invention discloses a tank car joint. The tank car joint comprises a joint body. The joint body comprises a female head and a handle. The handle is movably connected with the female head through abolt. Clamping jaws are symmetrically arranged above the female head along the axis. A corrugated clamping groove is formed in the upper end of the inner wall of the female head. A thread is arrangedat the lower end of the inner wall of the female head. A sealing gasket A is arranged below the clamping groove. A sealing gasket B is arranged above the thread. The sealing gasket A is arranged above the sealing gasket B. A certain distance is reserved between the sealing gasket A and the sealing gasket B. The handle is an anti-vibration handle, and the rotatable angle range of the handle is 0-45 degrees. The tank car joint is provided with the movable anti-vibration handle, handle looseness is avoided, and matched installation is made convenient and fast. According to the tank car joint, stable connection of the joint can be decided by high-precision machining, the sealing gasket A and the sealing gasket B are arranged and thus the overall sealing property is good.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a tank car joint. Background technique [0002] The pipe joint is a connection tool between pipes and a detachable connection point between components and pipes, and plays an indispensable and important role in pipe fittings. There are many kinds of pipe joints used for tank car pipeline connection. The traditional tank car pipe joints have low sealing performance, and the plug-type handle is conventionally used. The disadvantage is that the handle will loosen after a certain period of time and times of use; The lock handle, that is, the handle is fixed on the basis of the original bolt type. The disadvantage is that the handle with the lock must be kept clean, otherwise the lock groove will be easily blocked and it is inconvenient to unlock. [0003] Therefore, in the prior art, the sealing performance of tank car pipe joints is low, and the bolt-type handle is conv...

Problems solved by technology

[0004] Purpose of the invention: Aiming at the defects and insufficiencies of the prior art, solve the problem of low sealing performance of tank car pipe joints. The conventional use of pin-type handles has the disadvantage that the handle will loosen after a certain period of time and times of use; traditional tank car pipe joints also use locks The handle, that is, the handle is fixed on the basis of the original bolt type. The disadvantage is that the lock of the handle must be kept clean, otherwise the lock groove is easy to block and it is inconvenient to unlock. The applicant has improved through many practices and designed a tank car connector
