Abstract

The utility model relates to a back-end integration bus of a high-pressure gas long-pipe transport semi-trailer. A gas cylinder is fixed in a frame; a back-end plug is fixed on the back-end opening of the gas cylinder in a sealing mode; a safety device is fixed on the back-end plug in a sealing mode; a vent pipe is fixed on the safety device in a sealing mode; one channel of the back-end plug is communicated with a 90 degree elbow, a taper sealing welding joint and an NPT1/4' ball valve through an NPT1/2'gas inlet and gas outlet ball valve and a 450 degree coiled pipe in a sealing mode; the other channel of the back-end plug is communicated with an NPT1' total control ball valve and a collection pipeline through a rapid installing joint in a sealing mode; the NPT1/4'ball valve is communicated with a sewage discharge collection pipe through a 150 degree sewage discharge coiled pipe in a sealing mode. According to the back-end integration bus of the high-pressure gas long-pipe transport semi-trailer, the problems that a large diameter gas cylinder long-pipe semi-trailer is inconvenient to install, a drainage discharge pipeline is easy to leak, and welding seams are easy to crack are solved, the integration bus design is innovative, the drainage discharge pipeline is improved, and accordingly an safe and reliable integration bus pipeline is achieved.

Description

Long high-pressure gas pipe conveying semi-trailer rear end integration bus bar
Technical field
The utility model belongs to pressurized gas semitrailer technical field, particularly relates to a kind of six pipe long high-pressure gas pipe conveying semi-trailer rear end integration bus bars, is the innovation of operation equipment linkage structure in rear end in long-tube trailer.
Background technique
Along with the application of long high-pressure gas pipe conveying semi-trailer, novel long high-pressure gas pipe conveying semi-trailer constantly occurs.According to the structural change of new model, and the experience accumulation in production process, long high-pressure gas pipe conveying semi-trailer rear end integration bus bar structure is also being constantly brought forth new ideas.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of long high-pressure gas pipe conveying semi-trailer rear end integration bus bar, it is suitable for the rear end integration bus bar that six pipe high pressure gas long pipe semitrailers are used, having solved major diameter gas cylinder long tube semitrailer cylinder manifold installs inconvenient, blowoff line is easily revealed, and weld seam is the problem of cracking easily.The cylinder manifold design of innovation, the improvement of blowoff line, realized the safe and reliable of cylinder manifold pipeline.
The technical scheme in the invention for solving the technical problem is: gas cylinder is fixed in framework, the fixing rear end plug of sealing on the rear port of gas cylinder, and rear end seals fixing safety installations beyond the Great Wall, the fixing blow-down pipe of sealing on safety installations; Rear end plug passes through NPT1/2 " turnover balloon valve, 450 ° of coiled pipe one tunnels with 90 ° of elbows, bore seal welding joint and NPT1/4 " ball valve sealing communicates, separately lead up to ready-packaged joint and NPT1 " master control ball valve, gather line seal and communicate, described NPT1/4 " ball valve communicates with the sealing of blowdown gathering tube by 150 ° of blowdown coiled pipes.
1), adopt two kinds of symmetrical safety installationss the utlity model has following advantage:, guarantee in the situation that safety relief device is easy for installation, all air inlet and outlet end mouths of pipe upwards, install by convenient turnover air pipe; 2), turnover air pipe adopts 450 ° of coiled pipes, increases steel tube elastic, after 450 ° of coiled pipes are connected with 90 ° of elbows, total interface direction is downwards, facilitates the installation of whole turnover air pipe; 3), blowoff line adopts 150 ° of blowdown coiled pipes, strengthens blowoff line elasticity, also keeps steel tube elastic to prevent the tension failure of soldering point simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
