High-pressure gas long pipe semitrailer back-end integration bus bar

Abstract

The invention relates to a high-pressure gas long pipe semitrailer back-end integration bus bar, belonging to the technical field of high-pressure gas cylinder semitrailers. The high-pressure gas long pipe semitrailer back-end integration bus bar comprises a rear-end plug, an O-shaped seal ring, a K-shaped check ring, a safety device, an escape pipe, a flared type mal stud fitting, an NPT 1/2 gas pass in and out ball valve, a cone seal welding point, a collection pipe, an NPT 1 master control ball valve, a quick-release coupling, an air bleeder, an interior blow-off pipe, an external pollution discharging device, escape pipe fixing rubber, a dust cap, an operation bin top plate, an air cylinder, a frame and a coiler. The invention solves the problems on rotation of the escape pipe of the semitrailer back-end integration bus bar during the transportation, sealing between the escape pipe and the top plate as well as rain and dust prevention and sewage discharge of the escape pipe of the safety device, and achieves the purposes of safety and reliability. The size of the operation bin in the length direction is controlled to be 380mm through accurate calculation in the design, the size of a steel cylinder is increased under the condition of no overweight and overlength, and the water capacity is increased.

Description

technical field [0001] The invention belongs to the technical field of high-pressure gas cylinder semi-trailers, in particular to a rear-end integrated bus bar of a high-pressure gas long tube semi-trailer. It is an update of the connecting structure of the rear-end operating device in the long-tube trailer. Background technique [0002] At present, with the application and promotion of long-tube trailers, some insurmountable problems have appeared in use. One is that the bursting disc explodes by mistake, which is low-pressure blasting, which affects the normal use of users; second, during operation, if the vent tube rotates, It is easy to cause loosening of the connection thread between the safety device and the end plug, and between the end plug and the gas cylinder, which brings hidden dangers to use. The inability to carry out sewage discharge operations on a regular basis also brings hidden dangers to the use of trailers. Contents of the invention [0003] The purp...
